Technical Field

The invention belongs to the field of machining, and particularly relates to an auxiliary supporting device and control equipment.

Background

For parts such as a box body, a box cover, a shell and the like, under the condition that the machining precision requirement is mostly one hundredth or several thousandths of a millimeter, the precision requirement of a product can be influenced by careless machining in the cutting process, the requirement on the machining speed is higher in the current production, and the cutting force generated in the larger and faster cutting process often exceeds the bending strength of a machined surface material, so that the precision of the product is influenced.

In order to prevent the processed surface from deforming downwards due to the influence of cutting force in the cutting process, an auxiliary supporting device can be arranged to support the processed surface on the reverse side of the processed surface so as to ensure that the processed surface does not deform at all in the processing process. However, since some special-shaped pieces, or blanks, or positions to be clamped are not datum planes, the conventional clamping method used in mass production has the problems of unreliable clamping, part deformation and poor precision consistency.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In practical application, when the part 1 to be processed needs to be supported, the lifting assembly drives the supporting assembly to lift on the guide assembly, when the lifting assembly rises to the lifting limit of the lifting assembly, the supporting assembly starts to eject, and when the supporting assembly meets the part 1 to be processed and generates certain resistance with the part 1 to be processed in the ejection process, the ejection is stopped and the locking is carried out, so that the part 1 to be processed is supported; the height of the support assembly can be fine-tuned by the adjustment assembly. In the embodiment of the invention, the supporting component is arranged to support the part 1 to be processed, so that the processed surface of the part is ensured not to deform in the processing process; the auxiliary supporting device can realize the auxiliary supporting operation with large stroke by arranging the lifting assembly and the guide assembly; through setting up adjusting part, can finely tune the height of supporting component for this supplementary strutting arrangement can adapt to the support operation to different specification parts.

As shown in fig. 1, as a preferred embodiment of the present invention, the support assembly includes:

an auxiliary oil cylinder 3; the auxiliary oil cylinder 3 is connected with the guide assembly through the adjusting assembly;

a first piston rod 2; the first piston rod 2 is connected with the auxiliary oil cylinder 3.

Specifically, the auxiliary cylinder 3 drives the first piston rod 2 to ascend and descend, and when the first piston rod 2 contacts with the part 1 to be processed and generates resistance of about 10N, the auxiliary cylinder 3 stops the first piston rod 2 from being ejected out and locks the first piston rod 2. The auxiliary cylinder 3 raises the first piston rod 2 within a range of 1 to 6 mm.

As shown in fig. 1, as a preferred embodiment of the present invention, the lifting assembly includes:

a second piston rod 6; the second piston rod 6 is connected with the supporting component through the adjusting component;

a stroke cylinder 8; the second piston rod 6 is connected with the stroke oil cylinder 8.

Specifically, the stroke oil cylinder 8 drives the second piston rod 6 to lift, and the second piston rod 6 drives the supporting component to lift on the guiding component through the adjusting component. When the stroke oil cylinder 8 drives the second piston rod 6 to ascend to the ascending limit of the second piston rod 6, the supporting assembly starts to eject.

As shown in fig. 1, as a preferred embodiment of the present invention, the guide assembly includes:

a guide 5; the guide 5 is connected with the adjusting component;

a guide sleeve 7; the guide piece 5 is arranged in the guide sleeve 7 in a sliding mode.

As shown in fig. 1, as a preferred embodiment of the present invention, the adjusting assembly includes:

a connecting piece 4; the auxiliary oil cylinder 3 is fixedly arranged on the connecting piece 4; the connecting piece 4 is connected with the guide piece 5;

a nut 16; the nut 16 is arranged between the second piston rod 6 and the connecting piece 4; the nut 16 is connected with the connecting piece 4;

a screw 17; the screw 17 is connected with the second piston rod 6; the nut 16 is arranged on the threaded rod 17.

In particular, the coupling element 4 is moved by adjusting the nut 16 on the screw 17, so that the coupling element 4, and therefore the height of the support assembly, is changed.

As shown in fig. 1, as a preferred embodiment of the present invention, the auxiliary supporting device further includes:

a cylinder block 9; the stroke oil cylinder 8 is arranged in the oil cylinder seat 9; the guide sleeve 7 is arranged on the oil cylinder seat 9; the stroke oil cylinder 8 is connected with the guide piece 5 through the oil cylinder seat 9 and the guide sleeve 7;

a clamp body 10; the oil cylinder seat 9 is arranged on the clamp body 10.

As shown in fig. 2, an embodiment of the present invention further provides a control apparatus including any one of the auxiliary supporting devices, the control apparatus further including:

a hydraulic station 14 for powering the support assembly and the lifting assembly;

a sequence control valve 15; when the lifting assembly rises to the self-rising limit, the sequence control valve 15 is conducted, and the hydraulic station 14 provides power for the supporting assembly through the sequence control valve 15, so that the supporting assembly supports the part 1 to be processed.

Specifically, when the auxiliary supporting device works, the hydraulic station 14 enables pressure fluid to enter the stroke oil cylinder 8 to push the stroke second piston rod 6 to ascend. During the raising of the second piston rod 6, the pressure of the pressure fluid is not sufficient to open the sequence control valve 15. When the second piston rod 6 rises to the rising limit of the second piston rod, the pressure of the pressure liquid is increased, the sequence control valve 15 is conducted, and the pressure liquid enters the auxiliary oil cylinder 3 to push the first piston rod 2 to rise. When the first piston rod 2 returns, the pressure of the pressure fluid decreases, the sequence control valve 15 is closed, and the second piston rod 6 returns along with the return of the pressure fluid to the hydraulic station 14.

As shown in fig. 2, as a preferred embodiment of the present invention, the control apparatus further includes:

an electromagnetic directional valve 11 for controlling the flow of pressure fluid out of or into the pressure station;

and a pressure relay 13 for adjusting the pressure of the pressure fluid.

Specifically, when the auxiliary supporting device works, the electromagnetic directional valve 11 is electrified and connected, and the pressure liquid enters the stroke oil cylinder 8 through the electromagnetic directional valve 11. When the first piston rod 2 is returned, the pressure fluid is returned to the hydraulic pressure station 14 through the electromagnetic directional valve 11. The check throttle valve 12 enables the pressure fluid to flow only in one direction, and avoids backflow of the pressure fluid.

In conclusion, when the part 1 to be processed needs to be supported, the stroke oil cylinder 8 drives the second piston rod 6 to ascend and descend, and the second piston rod 6 drives the supporting component to ascend and descend on the guiding component through the adjusting component. When the stroke oil cylinder 8 drives the second piston rod 6 to ascend to the ascending limit of the second piston rod 6, the auxiliary oil cylinder 3 drives the first piston rod 2 to ascend and descend, and when the first piston rod 2 is in contact with the part 1 to be processed and generates resistance of about 10N, the auxiliary oil cylinder 3 enables the first piston rod 2 to stop ejecting and lock the first piston rod 2. At this time, the nut 16 is adjusted to move on the screw 17, so that the connecting piece 4 moves, and the connecting piece 4 further changes the height of the supporting component, so that the auxiliary supporting device can adapt to the supporting operation of parts with different specifications.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
