Technical Field

The invention relates to the technical field of assembly equipment, in particular to a tool device for keeping two workpieces in a relative position state.

Background

Tooling devices are known at least for holding a workpiece to be machined or assembled on a tooling mechanism.

To maintain the following description of the embodiments of the present invention clear and concise, a detailed description of known functions and known components of the invention have been omitted.

The invention aims to disclose a tooling device, which is used for keeping the relative fixed positions of two workpieces, such as a disc body 100 and a hub body 200 of a brake disc shown in figure 1. After operation of the tooling apparatus of the present invention, the two workpieces may be transported through assembly line 70 to the next workpiece for assembly in a fixed connection.

In the following, all the embodiments are described with the disc body 100 of the brake disc as a first workpiece and the hub body 200 of the brake disc as a second workpiece, however, this is not to be construed that the tooling device of the present invention is only used for operating the disc body 100 and the hub body 200.

As shown in fig. 2 to 21, a tooling device disclosed in an embodiment of the present invention includes: the worktable 40, the tooling mechanism 30, the top cover 60 and the driving mechanism 50. As shown in fig. 9, the table 40 is disposed below a preset position of the assembly line 70 in which a position for enabling the disc body 100 and the hub body 200 to be relatively fixed is held on the tooling mechanism 30. The tooling mechanism 30 is disposed on the assembly line 70 such that the tooling mechanism 30 can be transported to a predetermined position, i.e., above the worktable 40, by the assembly line 70. The tray 100 is placed on the tooling mechanism 30 by other means or manually before the tooling mechanism 30 is transported to the table 40. As shown in fig. 11, a first hollow portion 41 is formed on the working platform 40, the top sleeve 60 is opposite to the first hollow portion 41, the driving mechanism 50 is configured to drive the top sleeve 60 to move up and down, so that the top sleeve 60 can penetrate through the working platform 40 via the first hollow portion 41, as shown in fig. 12, the top sleeve 60 is configured to support the hub 200, and before the tooling mechanism 30 is conveyed above the working platform 40, the hub 200 is conveyed onto the top sleeve 60 via other devices, for example, as shown in fig. 9, the chuck 300 having a horizontal movement and vertical feeding function.

It should be noted that: before the tooling mechanism 30 is transported above the worktable 40, the driving mechanism 50 lowers the top sleeve 60 to drive the hub 200 to descend, aiming at: and the tooling mechanism 30 is avoided, so that the tooling mechanism 30 can be conveyed to the front of the working platform without interference.

In the present embodiment, as shown in fig. 5, the tool mechanism 30 has a through hole 13, the inner hole of the disk 100 is coaxial with the through hole 13, and the check mechanism 20 is provided in a position radially close to the region surrounded by the hole wall of the through hole 13. As shown in fig. 13 to 21, when the tooling mechanism 30 is transported to the upper side of the workbench 40 by the assembly line 70, the check mechanism 20 is used for allowing the hub 200 to pass through the through hole 13 when the top cover 60 of the hub 200 is lifted up through the first hollow portion 41 by the driving mechanism 50 and passes through the through hole 13, and supporting the hub 200 when the second workpiece is lifted up to the upper side of the check mechanism 20.

It should be noted that: the region enclosed by the wall of the bore 13 is understood to be a cylindrical region of cross-section corresponding to the bore 13, the length of which in the axial direction can be greater than the length of the bore 13 in the axial direction. That is, the check mechanism 20 may be provided above or below the through hole 13, and the position of the check mechanism 20 may be affected by the relative positional relationship in the axial direction required for the two workpieces. For example, in the disc body 100 and the hub body 200, the check mechanisms 20 are provided at the upper end and the lower end of the through hole 13, so that the relative positional relationship between the two can be more easily satisfied.

In the present invention, the driving mechanism 50 is used to drive the top sleeve 60 to ascend, and the check mechanism 20 provided on the tooling mechanism 30 is used to enable the second workpiece to be held on the tooling mechanism 30 in a relatively fixed positional relationship with the first workpiece horizontally conveyed to a preset position on the assembly line 70, and it is important that: when the second workpiece is mounted on the tooling mechanism 30, the first workpiece cannot be separated from the tooling mechanism 30 temporarily in order to avoid the second workpiece, so that the process of mounting the two workpieces on the tooling mechanism 30 becomes simple and efficient.

In an alternative embodiment of the present invention, as shown in fig. 5, the tooling mechanism 30 further includes a holding body 10, the through hole 13 is formed on the holding body 10, as shown in fig. 7, the disc 100 is placed on the holding body 10, and the check mechanism 20 is disposed on the holding body 10. As shown in fig. 5 and 7, the non-return mechanism 20 includes a stop block 21 and an elastic member 22, the stop block 21 can move horizontally and radially to partially extend into the area enveloped by the hole wall of the through hole 13 by moving radially and retract by moving radially outward, and the elastic member 22 is used for pushing the stop block 21 in a radially inward direction. In the present embodiment, a portion of the stopper 21 that can protrude into the region included in the hole wall of the through hole 13 is formed with a bearing surface 214 and an inclined surface 213 located below the bearing surface 214, and the inclined surface 213 is inclined radially outward from top to bottom.

The reason why the above-described embodiment enables the hub 200 to be held by the holding body 10 by being moved upward from below the holding body 10 is that:

as shown in fig. 13, when the tooling mechanism 30 is conveyed to the upper side of the workbench 40 by the assembly line 70, the hub body 200 which is already placed on the top sleeve 60 and is positioned below the tooling mechanism 30 moves upwards under the driving of the driving mechanism 50, as shown in fig. 14 to 21, when the hub body 200 passes through the through hole 13, the edge of the coupling block 201 of the hub body 200 first contacts with the inclined surface 213 of the stopper block 21, then the upward movement of the hub body 200 forces the stopper block 21 to move in the radial outward direction by sliding the edge of the upper end of the coupling block 201 on the inclined surface 213 to avoid the hub body 200, at this time, the elastic member 22 accumulates elastic potential energy, when the edge of the lower end of the coupling block 201 of the hub body 200 just departs from the stopper block 21, the stopper block 21 is released from the pressing of the coupling block 201 of the hub body 200, the elastic potential energy of the elastic member 22 is released to push the stopper block 21 to extend into the region enveloped by the hole wall of, the support surface 214 supports the bottom of the coupling block 201 of the hub 200, and at this time, the hub 200 and the disc 100 on the holder 10 are in a relatively fixed positional relationship, and at this time, the coupling block 201 of the hub 200 is opposite to the coupling block 101 of the disc 100 and is positioned below the coupling block 101 of the disc 100. In the present embodiment, the stopper 21 that can move in the radial direction, and the inclined surface 213 and the receiving surface 214 formed on the stopper 21 allow the hub 200 to pass through the through hole 13 from the bottom to the top and be received by the receiving surface 214 and held by the tool mechanism 30.

In an alternative embodiment of the invention, as shown in fig. 5, the non-return means 20 is located between the upper and lower ends of the bore 13. In this embodiment, the holding body 10 includes a plate 11 and a sheath 12, a through hole is formed in the middle of the plate 11, a flange 121 is formed on the lower end surface of the sheath 12 to detachably connect with the plate by a fastening member, and the inner hole of the sheath 12 is coaxial with the through hole, and the through hole and the inner hole of the sheath 12 form the through hole 13. In this embodiment, the tray 100 is sleeved on the sleeve 12, so that the tray 100 can be stably positioned on the holder 10; in addition, the sleeve body 12 increases the axial dimension of the through hole 13, which is beneficial to ensure that the combination block 201 of the hub body 200 can still be limited by the hole wall of the through hole 13 when the hub body 200 is supported by the bearing surface 214 of the stop block 21, thereby improving the positioning stability of the disc body 100 and the hub body 200. In the present embodiment, the workpieces having similar structures as the disc 100 and the hub 200 are provided with the sleeve body 12 to achieve this effect.

In an alternative embodiment of the present invention, as shown in fig. 5 and 6, a guide groove 14 (the upper side of the guide groove 14 is covered by a flange 121) is formed on the upper end surface of the plate-like body 11, and the guide groove 14 radially extends to penetrate the through hole 13. The stopper 21 includes a guide portion 212 and a stopper portion 211 which are integrally formed, the guide portion 212 extends into the guide groove 14, and the elastic member 22 is disposed in the guide groove 14 and between the groove bottom of the guide groove 14 and the guide portion 212. The stopping portion 211 is a portion of the stopping block 21 extending into the through hole 13 (or a portion of the stopping block extending out of the hole wall of the through hole 13), the supporting surface 214 is formed at the upper end of the stopping portion 211, and the inclined surface 213 is also formed at the stopping portion 211. In the present embodiment, as shown in fig. 5, the stopper portion 211 is formed to have a certain length in the axial direction, which allows the stopper portion 211 to have a long contact stroke with the first workpiece such as the hub 200 during the process of moving the first workpiece through the through hole 13, thereby contributing to the stability of the process of forming the through hole 13 in the first workpiece.

In a preferred embodiment of the present invention, as shown in fig. 6 in combination with fig. 5, the guide portion 212 is provided at both sides thereof with a stopper portion 2122, and when the stopper portion 211 is inserted into the through hole 13, the stopper portion 2122 contacts the stepped surface 141 formed at the guide groove 14 to restrict the stopper piece 21 from coming out of the guide groove 14 radially inward when the stopper piece 21 is not in contact with the coupling piece 201 of the hub body 200.

In a preferred embodiment of the present invention, as shown in fig. 5, a blind hole 2121 is opened radially inward at one end of the guide portion 212 facing the groove bottom of the guide groove 14; wherein: the elastic element 22 is a spring, and the spring part extends into the blind hole 2121; a ball 23 is also arranged between the spring and the groove bottom of the guide groove 14, and the ball 23 is partially located in the blind hole 2121 when the stopper 211 extends into the through hole 13. In this embodiment: the blind holes 2121 are arranged to save space for installing the spring; by providing the ball 23 and allowing the ball 23 to slide into the blind hole 2121, there is a guiding effect on the radial movement of the stop block 21 (as shown in fig. 20, most or all of the ball 23 slides into the blind hole 2121 after the stop portion 211 is retracted).

In order to improve the stability and uniformity of the support of the first workpiece, a plurality of non-return mechanisms 20 are circumferentially arranged along the center of the through hole 13, so that the first workpiece is supported by the support surfaces 214 on the plurality of circumferentially arranged stop blocks 21 after being penetrated through the through hole 13.

An alternative embodiment of the present invention provides a configuration for the drive mechanism 50. As shown in fig. 8 in conjunction with fig. 14 to 21, the driving mechanism 50 includes a first telescopic cylinder 51, a second telescopic cylinder 52, a first mounting plate 53, a second mounting plate 54, a tray 55, a first guide post 56, and a second guide post. The first mounting plate 53 is fixed below the table 40 by a plurality of first guide posts 56, the cylinder body of the first telescopic cylinder 51 is fixed at the bottom of the first mounting plate 53, and the telescopic rod 511 penetrates the first mounting plate 53. The second mounting plate 54 is disposed above the first mounting plate 53, the first guide column 56 penetrates the second mounting plate 54, the second mounting plate 54 can be lifted under the guidance of the first guide column 56, and the expansion rod 511 of the first expansion cylinder 51 is connected to the second mounting plate 54 to be lifted by driving the second mounting plate 54 to expand and contract. The top cover 60 is fixed to the second mounting plate 54 and is lifted by lifting and lowering the second mounting plate 54. The cylinder body of the second telescopic cylinder 52 is fixed at the bottom of the workbench 40, the telescopic rod 521 penetrates through the workbench 40, the tray 55 is arranged above the workbench 40, the telescopic rod 521 of the second telescopic cylinder 52 is connected to the tray 55, a plurality of second guide posts are fixed at the bottom of the tray 55 and penetrate through the workbench 40 so that the tray 55 can ascend and descend under the guidance of the second guide posts, the telescopic rod 521 of the second telescopic cylinder 52 is used for driving the tray 55 to ascend and descend, and the tray 55 is provided with a second hollow part 551 allowing the top sleeve 60 to penetrate through.

Next, the process of the tool device of the present invention for assembling the disc 100 and the hub 200 by the driving mechanism 50 is described as follows:

first, as shown in fig. 11, the extendable rod 511 of the first extendable cylinder 51 and the extendable rod 521 of the second extendable cylinder 52 are retracted, and at this time, the top cover 60 is at the lowest position along with the second attachment plate 54, and the tray 55 is also at the lowest position.

Then, as shown in fig. 12, the extension rod 511 of the first extension cylinder 51 is extended, the top cover 60 is raised to the uppermost position, the hub 200 is placed on the top cover 60 by the chuck 300 capable of performing the horizontal linear feeding and the vertical feeding, and the top cover 60 abuts against the bottom of the coupling block 201.

Then, when the extendable rod 511 of the first extendable cylinder 51 is retracted to escape the tooling mechanism 30 and the tooling mechanism 30 is transported to above the table 40 under the transport of the assembly line 70 as shown in fig. 13, the extendable rod 521 of the second extendable cylinder 52 is extended and the tray 55 is raised to support the plate-like body 11 of the tooling mechanism 30 as shown in fig. 14 and 15.

Then, as shown in fig. 16 and 17, the telescopic rod 521 of the second telescopic cylinder 52 is extended, the top sleeve 60 is raised to drive the hub 200 to rise to penetrate through the first hollow portion 41 and the second hollow portion 551, when the edge of the upper end of the combining block 201 on which the hub 200 rises contacts the inclined surface 213 of the stop block 21 of the tooling mechanism 30, the rising action of the hub 200 retracts the stop block 21 to avoid the combining block 201, so that, as shown in fig. 18 and 19, the hub 200 continues to rise and the outer end surface of the combining block 201 contacts the inner end surface of the stop block 21 (specifically, the stop portion 211) for a certain stroke.

The hub body 200 is further raised, and as shown in fig. 20 and 21, when the lower end of the coupling block 201 just releases the pressing on the stopper 21, the spring makes the stopper 21 extend out of the hole wall of the through hole 13 again, at this time, the hub body 200 stops rising, and the bearing surface 214 of the stopper 21 is opposite to the bottom edge of the coupling block 201.

Then, the extension rod 511 of the first extension cylinder 51 is retracted, the top cover 60 moves downward, and the hub 200 is supported on the support surface 214 of the stopper 21 by the coupling block 201 and is held by the tooling mechanism 30.

The extension rod 511 of the first extension and contraction cylinder 51 continues to retract and causes the ejection sleeve 60 to retract to the lowest position.

Then, the extendable rod 521 of the second extendable cylinder 52 is retracted to the lowest position, and at this time, the tray 55 is separated from the plate-like body 11, and the support of the tool mechanism 30 is released, and at this time, the tool mechanism 30 holding the disc body 100 and the hub body 200 at the same time is conveyed to the next step by the assembly line 70.

In some alternative embodiments, as shown in fig. 11, the positioning posts 552 are disposed on the tray 55, and the positioning slots are disposed at the bottom of the plate-shaped body 11, so that when the tray 55 supports the tooling mechanism 30, the positioning posts 552 extend into the positioning holes of the plate-shaped body 11 to position the tooling mechanism 30, thereby limiting the horizontal movement thereof.
