[0002] At present, in the processing of daily non-standard steel structures, in order to ensure the quality of steel parts, reduce the labor intensity of workers and improve the production efficiency of factories, pneumatic clamps have been widely used.

[0003] After inquiry, the publication number: CN215617586U discloses a positioning fixture for stamping part processing. In this technology, it is disclosed that "it includes a positioning assembly, a first clamping assembly and a second clamping assembly. The threaded sleeve is fixed at one end above the support frame, the rotating handwheel is fixed at one end of the threaded rod, and the buffer positioning plate is fixedly connected to one side of the connecting plate. The first screw rod and the second screw rod are fixedly connected between them. One end of the first screw rod is connected to the output end of the motor, one end of the second screw rod is rotatably connected above the support frame, the connecting sleeve is threadedly sleeved on the first screw rod and the second screw rod, and the adjusting clamping plate is hinged to one end of the connecting sleeve and other technical solutions, which have the technical effects of being beneficial to positioning the stamping part, reducing the offset of the stamping part, improving the clamping effect on the stamping part, and being beneficial to clamping stamping parts of different heights".

[0004] Regarding the above related technologies, the inventor believes that firstly, in the clamping head structure of the existing clamping assembly for stamping parts, the clamping head is generally set in a fixed shape. Since the shapes of different stamping parts are different, using one type of clamping head to clamp and fix the stamping part cannot achieve a good clamping effect, and there is no quick-release component, so it is not convenient to replace the clamping head in the clamping assembly structure according to the actual situation; secondly, the existing clamping assembly does not have a structure for turning the stamping part. In order to better process the stamping part, sometimes it is necessary to change the clamping direction of the placed stamping part. Currently, it is generally manual, which is time-consuming and laborious, and there is no turning mechanism, so it is not convenient to quickly change the clamping direction of the stamping part. Summary of the Utility Model

[0005] The purpose of the present application is to provide a positioning and clamping assembly for stamping parts to improve the problems that the existing clamping assembly structure is not convenient to replace the clamping head in the clamping assembly structure according to the actual situation and is not convenient to quickly change the clamping direction of the clamped stamping part.

[0006] A positioning and clamping assembly for stamping parts provided by the present application adopts the following technical solutions:

[0007] A positioning and clamping assembly for stamping parts, including a bottom shell. A steering mechanism is arranged inside the bottom shell. Both sides of the top end of the bottom shell are fixedly connected with support seats. The top ends of both support seats are fixedly connected with cylinders, and the output ends of both cylinders are fixedly connected with vertical plates. One end of both vertical plates is provided with a quick-release assembly, and one end of both quick-release assemblies is fixedly connected with a clamping head.

The rotation of the worm gear drives the round rod to rotate. The rotation of the round rod drives the first pulley to rotate. The rotation of the first pulley in cooperation with the conveyor belt and the second pulley makes the vertical rod rotate. The rotation of the vertical rod drives the placement table to rotate, so that the direction of the stamping part on the placement table is changed, and the clamping head clamps different positions on the stamping part to facilitate the processing of the stamping part.

[0011] Optionally, the two clamping heads are mirror-symmetrically distributed, and the internal structures of the two quick-release assemblies are the same.

[0012] By adopting the above technical solution, the mirror-symmetric distribution is convenient for the clamping head to better clamp the stamping part, and the same internal structure is convenient for the operation steps of the two quick-release assemblies to be the same.
