When the watch 70 is in different orientations, the parts inside the watch 70 may be displaced under the action of gravity, thereby affecting the accuracy of the travel time of the watch 70. The application provides a multi-functional position test machine of wrist-watch can be used to test the condition of walking time of wrist-watch 70 in each position to judge the accuracy of walking time of wrist-watch 70 in each position.

Example one

As shown in fig. 1 to 5, the multifunctional azimuth tester for a wristwatch includes a revolving mechanism 30, a rotating mechanism 40, a camera 50 and at least one work rest 20.

Wherein the work rest 20 may be used to mount the watch 70. The at least one workpiece rest 20 is rotatably mounted on a turntable 60, and the at least one workpiece rest 20 is disposed around a first axis 60a of the turntable 60.

The revolving mechanism 30 is in transmission connection with the rotating disc 60, and the revolving mechanism 30 can be used for driving the rotating disc 60 to rotate around the first axis 60a, so as to drive the at least one workpiece holder 20 to revolve around the first axis 60 a.

The rotation mechanism 40 is in transmission connection with the work holders 20, and any one of the work holders 20 is in transmission connection with the rotation mechanism 40. The workpiece holder 20 includes a second axis 201, and the rotation mechanism 40 is used for driving the workpiece holder 20 to rotate around the second axis 201.

The camera 50 is disposed corresponding to the at least one work rest 20, and the camera 50 can shoot the watch 70 mounted on the work rest 20 to obtain the travel time data of the watch 70.

In use, the workpiece holder 20 can be driven to rotate by the revolution mechanism 30 and the rotation mechanism 40, so that the watch 70 rotates to a preset direction for testing, that is, the watch 70 stays in the direction for a preset time period, and then the watch 70 can be shot by the camera 50, so as to obtain walking data of the watch 70 in the direction. It can be understood that, when the watch 70 is shot by the camera 50 to collect travel time data, the watch 70 at each position on the work rest 20 can be sequentially rotated by the rotation mechanism 40 to be opposite to the camera 50, so that the camera 50 can shoot and collect the data.

The revolution mechanism 30 can rotate the watch 70 to any direction in the revolution direction, and the rotation of 360 degrees can be realized. The rotation mechanism 40 can rotate the watch 70 to any direction in the rotation direction, and the 360-degree rotation can be realized. Therefore, the watch 70 can be rotated to more orientations under the cooperation of the revolution mechanism 30 and the rotation mechanism 40, so that more orientations of tests can be realized, and the detection data can be more reliable.

Therefore, the multifunctional azimuth testing machine for the watch provided by the application can realize the test of the watch 70 in a plurality of azimuths, so that the acquired data has higher reference value.

Example two

The embodiment provides a multifunctional azimuth testing machine for a watch, which can be used for detecting the accuracy of travel time of the watch 70 in multiple azimuths. It is understood that the present embodiment may be a further improvement on the first embodiment.

As shown in fig. 1 to 5, the multifunctional orientation testing machine for a wristwatch further includes a frame 10, and the frame 10 may be used to support other mechanisms of the multifunctional orientation testing machine for a wristwatch, and specifically, the revolving mechanism 30, the rotating mechanism 40, and the workpiece holder 20 may be directly or indirectly mounted on the frame 10.

In some embodiments, the rack 10 may have an inverted T shape, and the rack 10 may include a bottom plate 11 and a mounting plate 12 perpendicular to each other, wherein the bottom plate 11 may be disposed in a horizontal direction. The revolution mechanism 30, the rotation mechanism 40, the work rest 20, and the like are mounted on the mounting plate 12.

Referring to fig. 3 to 6, the revolution mechanism 30 may include a revolution motor 31 and a revolution shaft 32. The revolution motor 31 may be fixedly installed at one side of the mounting plate 12. The revolution shaft 32 is rotatably mounted on the mounting plate 12, two second bearings 35 are disposed between the revolution shaft 32 and the mounting plate 12, and the two second bearings 35 can be mounted in bearing holes in the mounting plate 12, thereby ensuring smooth rotation of the revolution shaft 32 relative to the mounting plate 12. The second bearing 35 may be disposed near the side wall of the mounting plate 12, and a retaining ring may be disposed at a side of the second bearing 35 near the side wall of the mounting plate 12 for limiting.

One end of the revolution shaft 32 is in transmission connection with the revolution motor 31, and the other end of the revolution shaft 32 is fixedly connected with the turntable 60, for example, the revolution shaft 32 and the turntable 60 can be relatively fixed through corresponding shaft keys and screws. In some embodiments, the revolution axis 32 may be parallel to the bottom plate 11. The revolution shaft 32 may extend from one side of the mounting plate 12 close to the revolution motor 31 to the other side of the mounting plate 12. Accordingly, the turntable 60 is disposed on a side of the mounting plate 12 away from the revolving motor 31. In one embodiment, the mounting plate 12 may also provide corresponding support for the revolution axis 32.

The revolution shaft 32 and the revolution motor 31 can be connected through gear transmission. Specifically, one end of the revolution shaft 32 close to the revolution motor 31 may be fixedly connected with a first straight gear 33, for example, the revolution shaft 32 and the first straight gear 33 may be fixedly connected through a shaft key and a screw, and the first straight gear 33 may be limited by a retaining ring, so as to prevent the first straight gear 33 from being separated from the revolution shaft 32. Correspondingly, the first output shaft 311 of the revolving motor 31 is fixedly connected with the second spur gear 34, and the second spur gear 34 is meshed with the first spur gear 33. The second spur gear 34 and the first output shaft 311 may be fixedly connected by a shaft key and a screw, and are limited by a retainer ring. Thus, the revolution motor 31 drives the revolution shaft 32 to rotate, and further drives the turntable 60 to rotate synchronously. In an embodiment, the turntable 60 may be parallel to the mounting plate 12, and the first axis 60a of the turntable 60 may be coaxial with the revolution axis 32.

In some embodiments, the rotation mechanism 40 may include a rotation motor 41 and a rotation shaft 46, and the rotation motor 41 may be configured to drive the rotation shaft 46 to rotate. The rotation shaft 46 is rotatably installed in the revolution shaft 32, and the revolution shaft 32 may be a hollow shaft. The rotation shaft 46 is coaxial with the revolution shaft 32, and both ends of the rotation shaft 46 protrude from the revolution shaft 32. Accordingly, two third bearings 47 are disposed between the rotation shaft 46 and the revolution shaft 32 to ensure that the rotation shaft 46 can rotate smoothly relative to the revolution shaft 32. In an embodiment, the third bearing 47 may be disposed near the end of the revolution shaft 32, and the third bearing 47 may be limited by a snap spring.

The rotation motor 41 is slidably installed at a side of the mounting plate 12 close to the revolution motor 31 such that the rotation motor 41 is close to or away from the rotation shaft 46. The rotation mechanism 40 further includes a clutch cylinder 42, and the clutch cylinder 42 is fixedly installed on one side of the mounting plate 12 close to the revolution motor 31. A sliding plate 43 is connected to an output end of the clutch cylinder 42, the sliding plate 43 is slidably mounted on the mounting plate 12, and the rotation motor 41 is fixedly mounted on the sliding plate 43. In operation, the clutch cylinder 42 can drive the sliding plate 43 to slide, and further drive the rotation motor 41 to move close to or away from the rotation shaft 46.

In an embodiment, when the rotation motor 41 is close to the rotation shaft 46, the rotation motor 41 may be in transmission connection with the rotation shaft 46. Specifically, the third spur gear 44 is fixedly connected to the second output shaft 411 of the rotation motor 41. A fourth spur gear 45 is fixedly connected to one end of the rotation shaft 46 close to the rotation motor 41, and the third spur gear 44 can be in meshed connection with the fourth spur gear 45. In use, the rotation motor 41 can be driven by the clutch cylinder 42 to approach the rotation shaft 46, so that the third spur gear 44 is meshed with the fourth spur gear 45, and the rotation shaft 46 can be driven by the rotation motor 41 to rotate.

In some embodiments, the end of spinning shaft 46 remote from spinning motor 41 is drivingly connected to workpiece holder 20, and workpiece holder 20 may be mounted to the side of turntable 60 remote from mounting plate 12. Specifically, one end of the rotation shaft 46, which is far away from the rotation motor 41, protrudes out of the revolution shaft 32, and extends to one side of the turntable 60, which is far away from the mounting plate 12. A first bevel gear 48 is fixedly connected to an end of the rotation shaft 46 away from the rotation motor 41, that is, the first bevel gear 48 may be disposed on a side of the turntable 60 away from the mounting plate 12. Illustratively, the rotation shaft 46 and the first bevel gear 48 can be fixed relative to each other by a second shaft key 461 and a screw. In one embodiment, the first bevel gear 48 may be coaxial with the rotation shaft 46, and the first bevel gear 48 may be rotated synchronously by the rotation shaft 46.

In some embodiments, the connecting shaft 22 is fixedly disposed at one end of the workpiece holder 20 close to the rotation shaft 46, and the second bevel gear 49 is fixedly disposed at one end of the connecting shaft 22 close to the rotation shaft 46, for example, the connecting shaft 22 and the second bevel gear 49 may be fixedly connected by a first shaft key 221 and a screw. The second bevel gear 49 may be in meshing connection with the first bevel gear 48, such that the first bevel gear 48 may drive the second bevel gear 49 to rotate, and further drive the connecting shaft 22 and the work rest 20 to rotate. In one embodiment, the connecting shaft 22 may be perpendicular to the rotation axis 46, and correspondingly, the second axis 201 of the work rest 20 is perpendicular to the first axis 60a of the turntable 60.

In one embodiment, the connecting shaft 22 is rotatably mounted on the turntable 60, and accordingly, the work piece carrier 20 is rotatably mounted on the turntable 60 via the connecting shaft 22. Specifically, a mounting seat 61 is convexly arranged on one side of the turntable 60 away from the mounting plate 12, and the connecting shaft 22 penetrates through the mounting seat 61 and is rotatably mounted relative to the mounting seat 61. The work carrier 20 and the second bevel gear 49 are provided on both sides of the mount 61. In addition, the mounting seat 61 can also provide corresponding support for the connecting shaft 22.

Two first bearings 222 may be disposed between the connecting shaft 22 and the mounting seat 61, and the two first bearings 222 may be mounted in bearing holes of the mounting seat 61, thereby ensuring smooth rotation of the connecting shaft 22 relative to the mounting seat 61. In an embodiment, a side of the first bearing 222 close to the workpiece holder 20 may be limited by a retaining ring (not shown) on the connecting shaft 22, and a side of the first bearing 222 close to the second bevel gear 49 may be limited by a bearing end cap 223, so that the first bearing 222 may be prevented from freely swinging, and the connecting shaft 22 may be ensured to smoothly rotate relative to the mounting seat 61. The bearing end cover 223 may be fixedly assembled to the mounting seat 61 by screws.

As shown in fig. 1 and 2, in some embodiments, the multi-functional orientation testing machine for watches includes four workpiece rests 20, namely a first workpiece rest 20a, a second workpiece rest 20b, a third workpiece rest 20c, and a fourth workpiece rest 20d, the four workpiece rests 20 being evenly spaced about the first axis 60 a. It can be understood that, a corresponding connecting shaft 22 and a corresponding second bevel gear 49 are connected to any one of the workpiece holders 20, and correspondingly, four second bevel gears 49 connected to four workpiece holders 20 are all connected to the first bevel gear 48 in a meshing manner, that is, the first bevel gear 48 can simultaneously drive the four workpiece holders 20 to rotate. The corresponding positions on the rotary table 60 are provided with an equal number of mounting seats 61 for respectively mounting the workpiece racks 20 at the corresponding positions.

In other embodiments, the multifunctional orientation testing machine for watches can be further configured to have one, two, three, five, etc. workpiece racks 20, and the workpiece racks 20 can be in transmission connection with the same first bevel gear 48, i.e. the rotation mechanism 40 can simultaneously drive a corresponding number of workpiece racks 20 to rotate.

In the embodiment, each of the four workpiece racks 20 is provided with a corresponding number (not shown) so as to identify the four workpiece racks 20 during the testing process.

The four mounting surfaces 21 can be arranged around the second axis 201 of the work rest 20, and the four mounting surfaces 21 are sequentially connected, and two adjacent mounting surfaces 21 can be perpendicular to each other.

In one embodiment, a mounting surface 21 has a plurality of resilient mounting brackets 211 mounted thereon, and the resilient mounting brackets 211 can be used to hold and secure the watch 70. Illustratively, one, five, ten, sixteen, twenty-five, thirty, forty, etc. elastic mounting brackets 211 may be provided on one mounting surface 21, and correspondingly, a corresponding number of watches 70 may be simultaneously mounted on one mounting surface 21. When the multifunctional direction testing machine is used, the multifunctional direction testing machine can complete the testing of a plurality of watches 70, so that the testing efficiency is improved. In one embodiment, the resilient mounting bracket 211 may comprise a pair of resilient clamping blocks disposed opposite to each other to clamp the watch 70, and may also be adapted to different sizes of watches.

In some embodiments, the camera 50 may be disposed opposite the turntable 60 with the viewing side of the camera 50 facing the turntable 60 side to facilitate the camera 50 in photographing the watch 70 on the work rest 20. The camera 50 may be fixedly mounted by a mounting base (not shown) and fixed relative to the housing 10.

In an embodiment, the camera 50 may be disposed coaxially with the first axis 60a, and the four work holders 20 are all within the viewing range of the camera 50, so that the camera 50 can shoot the watch 70 on the corresponding mounting surface 21 of the four work holders 20 at the same time.

It will be appreciated that the multi-function orientation testing machine may also include a control unit (not shown) for controlling the operation of other components of the multi-function orientation testing machine. The control unit may include a controller, a processor, and a memory. During operation, the camera 50 can also send the collected travel time data to the control unit, and the control unit can compare the collected travel time data with the standard time source and store the collected travel time data and the comparison result.

In an embodiment, the plurality of elastic mounting brackets 211 on the four workpiece racks 20 may be numbered, so as to identify each elastic mounting bracket 211 during the test process, so as to correspond to a corresponding watch 70, so as to obtain the test result corresponding to each watch 70 in the following.

In use, the watch 70 may be mounted on the resilient mounting 211 with the front of the watch 70 facing away from the workpiece holder 20. It will be appreciated that the front of watch 70 may refer to the side that the user sees when viewing time. The watch 70 is driven to rotate to each preset direction through the revolution mechanism 30 and the rotation mechanism 40, so that the watch 70 is tested for the travel accuracy of each preset direction.

Specifically, the clutch cylinder 42 drives the rotation motor 41 away from the rotation shaft 46, so that the third spur gear 44 is separated from the fourth spur gear 45. The revolution motor 31 is activated to rotate the four workpiece rests 20 in the revolution direction to the first preset direction of the first test stage, for example, the four workpiece rests 20 may be made to correspond to 12 o ' clock direction, 3 o ' clock direction, 6 o ' clock direction and 9 o ' clock direction one by one, wherein the first workpiece rest 20a may be made to correspond to 12 o ' clock direction.

The revolution motor 31 is turned off, the clutch cylinder 42 is started, and the rotation motor 41 is connected to the rotation shaft 46 in a transmission manner. The rotation motor 41 is activated to drive the four work holders 20 to rotate around their own second axes 201, and in the rotation direction, the watch 70 is rotated to the second preset direction corresponding to the first test sub-stage, for example, one mounting surface 21 in the work holder 20 may correspond to the camera 50, for example, the first mounting surface 21a may correspond to the camera 50.

The watch 70 may then be left in the preset orientation for a preset period of time for a timed test, such as three hours, four hours, five hours, six hours, eight hours, etc. After the timing test of the first test sub-stage is completed, the camera 50 may first collect travel time data of the first mounting surface 21a, and the control unit compares the collected travel time data with the standard time source and stores the data. And then, starting the rotation motor 41 to drive the workpiece holder 20 to rotate, so that the other three mounting surfaces 21 on the workpiece holder 20 sequentially correspond to the cameras 50 respectively, so that the cameras 50 can carry out travel time data acquisition on the watches 70 on the corresponding mounting surfaces 21, and meanwhile, the control unit finishes comparison with a standard time source and data storage.

After the data acquisition of the first testing sub-stage is completed, at this time, the fourth mounting surface 21d corresponds to the camera 50, and the positions of the four mounting surfaces 21 in the same workpiece holder 20 are all changed, that is, the watches 70 on the mounting surfaces 21 are respectively rotated to the second preset direction corresponding to the second testing sub-stage. The rotation motor 41 is turned off, and the wristwatch 70 is stopped at this position for a preset time period to perform the timing test of the second test sub-stage. After the timing test is completed, the travel data of the watch 70 in each mounting surface 21 can be collected through the camera 50, and the collected data is compared with a standard time source by the control unit and is stored.

Subsequently, the work rest 20 may be rotated, and the timing test may be performed while the third mounting surface 21c and the fourth mounting surface 21d are sequentially made to correspond to the camera 50, and corresponding data acquisition, comparison, and storage may be performed to complete the detection of the first test stage of the wristwatch 70, i.e., the wristwatch on the work rest 20 completes the test in the four rotation directions.

The clutch cylinder 42 is activated to disconnect the rotation motor 41 from the rotation shaft 46. The revolution motor 31 is started to rotate the four workpiece holders 20 by 90 ° correspondingly, and in the revolution direction, the four workpiece holders 20 are respectively rotated to the corresponding first preset direction in the second testing stage, for example, the first workpiece holder 20a is rotated from 12 o 'clock direction to 3 o' clock direction. Subsequently, the operations in the first test stage may be repeated.

The first workpiece holder 20a is sequentially rotated to the 6 o 'clock direction and the 9 o' clock direction by the revolution mechanism 30, that is, the third stage test and the fourth stage test are sequentially performed, and the third stage test and the fourth stage test may be the same as the first stage test operation, and are not described again here.

In other embodiments, when the revolving mechanism 30 revolves the workpiece holders 20, the workpiece holders 20 may be oriented in other directions. When the rotation mechanism 40 rotates each work holder 20, the corresponding mounting surface 21 is also oriented in another direction. The operator may also select a number of preset orientations as desired and rotate the watch 70 in sequence to the corresponding preset orientations for testing.

In other embodiments, the rotation motor 41 is close to the rotation shaft 46 through the clutch cylinder 42, so that the third spur gear 44 is in meshing connection with the fourth spur gear 45. The rotation motor 41 is turned off to make the rotation shaft 46 self-lock. The revolution motor 31 is started to drive each work carrier 20 to revolve. When the work rest 20 revolves, the second bevel gear 49 is moved along the tooth surface of the first bevel gear 48, and the second bevel gear 49 is rotated by the meshing action of the first bevel gear 48 and the second bevel gear 49, that is, the work rest 20 is rotated, whereby the revolving mechanism 30 and the rotating mechanism 40 are interlocked. In an embodiment, the wrist watch 70 may be sequentially rotated to a plurality of predetermined orientations for testing, and for example, when one of the mounting surfaces 21 in the work rest 20 is rotated to be opposite to the camera 50, the revolving motor 31 may be stopped, so that the wrist watch 70 performs timing tests at corresponding positions, and walking data of each wrist watch 70 may be collected through the camera 50.

In other embodiments, the clutch cylinder 42 can drive the self-driven motor 41 to approach the rotation shaft 46, so that the third spur gear 44 is meshed with the fourth spur gear 45. The revolution motor 31 and the automatic transmission motor 41 are started simultaneously, so that the workpiece holder 20 revolves and automatically transmits under double driving, the workpiece holder 20 is sequentially rotated to a plurality of preset positions for testing, the camera 50 can be used for tracking and monitoring, travel time data of the watch 70 in each preset direction can be collected, and the control unit processes the data. In the embodiment, the revolution motor 31 and the rotation motor 41 may be controlled to operate by the control unit.

In summary, the multifunctional orientation testing machine for a watch provided in the embodiments may include at least the following advantages:

the test device can realize the test in fixed directions (12 o 'clock direction, 3 o' clock direction, 6 o 'clock direction and 9 o' clock direction) and also can realize the test in non-fixed directions;

through automatic control, the test accuracy can be improved, and the measured data is more accurate and reliable;

and thirdly, the data of all directions can be acquired in real time, and the test accuracy is improved.
