Description

Technical Field

[0001] The present application relates to the technical field of parts polishing, and in particular to a clamp for polishing metal parts. Background Art

[0002] Most existing mechanical parts are manufactured using molds. After machining, some parts have rough surfaces that require grinding and polishing to meet factory standards. Traditional grippers lack versatility and are often only suitable for parts with regular shapes or require custom fixtures for unusual shapes. This results in different clamping methods for different types and sizes of metal parts. Companies need multiple gripping devices, increasing costs and management complexity. Adjustment and calibration are time-consuming when changing devices, impacting production efficiency. Utility Model Content

[0003] In order to solve the problem that traditional clamps have poor versatility and cannot adapt to different types of parts, the present application provides a clamp for polishing metal parts.

[0004] The present application provides a metal parts polishing clamp adopting the following technical solution:

[0005] A clamp for polishing metal parts includes a base with a guide groove, a moving assembly is arranged in the guide groove, the moving assembly includes a plurality of moving seats arranged in pairs in the guide groove, a linear actuator is provided on the moving seat, and a plurality of groups of clamping assemblies are provided on the moving seat, the clamping assembly includes two clamping plates arranged on the moving seat, a transmission assembly is provided between the two clamping plates, the transmission assembly includes two transmission members 2 respectively arranged on the corresponding clamping plates, and a rotatable transmission member 1 is provided on the inner side of the two transmission members 2, which is used to realize symmetrical linear motion of the two clamping plates with the rotation axis of the transmission member 1 as the center.

[0006] Preferably, a rotating shaft is provided on the movable seat, the transmission member is rotatably sleeved on the rotating shaft, a transmission plate is rotatably provided on the rotating shaft, and sliding grooves are provided at both ends of the transmission plate.

[0007] Preferably, the clamping plate is provided with a guide column, and the guide column is slidably arranged in the corresponding sliding groove.

[0008] Preferably, the clamping plate and the movable seat are provided with a guide structure for enabling the clamping plate to slide along the moving direction of the movable seat, and a rubber pad is provided at the end of the clamping plate.

[0009] Preferably, the first transmission member can be a gear, and the second transmission member can be a rack that matches the gear.

[0010] In summary, this application has the following beneficial technical effects:

[0011] By cooperating with the moving assembly, clamping assembly, transmission assembly, transmission plate and rubber pad, the linear actuator is used to drive the moving seat to move, so that the two clamping plates move and abut against the side wall of the part to clamp the part. If the clamping surface of the part is flat or symmetrical, the four clamping plates abut against the workpiece at the same time. If the part is special-shaped or the clamping surface is uneven and asymmetrical, one of the two clamping plates on the same side abuts against the side wall of the workpiece. At this time, the moving seat continues to move, and the transmission member 1 is misaligned with the abutting clamping plate. The transmission member 2 drives the transmission member 1 to rotate, so that the other clamping plate continues to move until it abuts against the workpiece, so that special-shaped workpieces can be clamped. Compared with the existing technology, it has a wide range of applications and high stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following is combined with Figure 1-3 This application is described in further detail.

[0017] The embodiment of the present application discloses a holder for polishing metal parts. Figure 1-3 A clamp for polishing metal parts, a base 1, the base 1 includes a support 101 with a guide groove, a connecting piece 102 is installed on the back of the support 101, and the connecting piece 102 can be fixed to the processing table of the polishing machine by bolts.

[0018] Reference Figure 2 The guide groove is provided with a moving assembly 2, which includes a plurality of linear actuators 201 mounted on the support 101. The linear actuator 201 can select suitable actuator components according to needs, such as a power telescopic cylinder or a screw. Figure 3In this application document, the linear actuator 201 uses a double-headed screw, with a movable seat 202 threadedly sleeved on both ends of the double-headed screw. A movable groove is provided on both sides of the double-headed screw on the support 101. A clamping assembly 3 is installed inside the movable groove. The clamping assembly 3 includes two clamping plates 301 installed on the movable seat 202. The clamping plates 301 and the movable seat 202 are installed with a guide structure. The guide structure includes a slider 203 installed on the movable seat 202. The bottom of the clamping plate 301 is provided with a sliding groove that is compatible with the slider 203. The slider 203 is slidably installed in the sliding groove, so that the clamping plate 301 can slide along the axial direction of the double-headed screw relative to the movable seat 202.

[0019] In order to prevent the surface of the metal parts from being damaged during the clamping process, the contact surface of each clamping plate 301 is covered with a layer of rubber pad 6, which not only increases the friction but also plays a buffering role, thereby protecting the parts from damage.

[0020] Reference Figure 2 A rotating shaft 204 is fixedly mounted on the linear actuator 201, and a transmission plate 5 is rotatably mounted on the rotating shaft 204. A guide post 302 is slidably mounted within each end of the transmission plate 5. The lower end of the guide post 302 is fixedly connected to the clamping plate 301. Using the principle of a lever and linkage, applying force to the guide post 302 at one end of the transmission plate 5 causes the transmission plate 5 to push the guide post 302 at the other end in a certain direction and limit the movement.

[0021] Reference Figure 1 A transmission assembly 4 is mounted between the two clamping plates 301. This assembly comprises two second transmission members 402, each mounted on a corresponding clamping plate 301. A rotatable first transmission member 401 is mounted within each second transmission member 402, enabling symmetrical linear motion of the two clamping plates 301 about the rotation axis of the first transmission member 401. The first and second transmission members 401 and 402 can be configured using suitable gears, rack combinations, friction wheels, or friction strips, as needed. In this application, the first transmission member 401 is a gear, and the second transmission member 402 is a rack compatible with the gear.

[0022] The implementation principle of the clamp for polishing metal parts in the embodiment of the present application is as follows:

[0023] When the linear actuator 201 is activated (the double-ended screw rotates), the two movable seats 202 are driven to move axially along the double-ended screw. Because the two clamping plates 301 of the clamping assembly 3 can slide relative to the movable seats 202 via a guide structure (a slider 203 provided on the movable seats 202 and a sliding groove provided at the bottom of the clamping plates 301 that matches the slider 203), when the movable seats 202 move, the clamping plates 301 also move with it.

[0024] When the clamping plates 301 contact the metal part, if the clamping surface of the part is flat or symmetrical, the four clamping plates 301 will abut against the workpiece at the same time to achieve preliminary clamping.

[0025] If the part is of special shape or the clamping surface is uneven or asymmetrical, when the movable seat 202 continues to move, one of the two clamping plates 301 on the same side may first abut against the side wall of the workpiece.

[0026] At this point, the transmission plate 5 is fixedly connected to the linear actuator 201 via the rotating shaft 204 and can rotate about it. Furthermore, both ends of the transmission plate 5 have slots within which slide guide posts 302 fixedly connected to the clamping plate 301. When the clamping plate 301 on one side stops moving, force is applied to the guide post 302 at one end of the transmission plate 5. Using the principle of a lever and linkage, the transmission plate 5 pushes the guide post 302 at the other end in the same direction, thus limiting the position.

[0027] At the same time, the transmission assembly 4 between the two clamping plates 301 starts to work. When one clamping plate 301 stops moving and the other clamping plate 301 needs to continue moving, the rack on the abutting clamping plate 301 drives the gear to rotate, which in turn drives the other rack to move, causing the other clamping plate 301 to continue moving until it abuts against the workpiece, completing the clamping of the irregular-shaped workpiece.
