Technical Field

[0001] The utility model relates to the technical field of workpiece clamping devices, in particular to a clamping device for clamp processing. Background Art

[0002] A clamp is a connection device for connecting grooved pipes, valves and pipe accessories. It is used to tighten quick connectors. Generally, the connector has gaskets, rubber, silicone and PTFE. For some control cabinets that need to control gas pipelines, the pipelines inside the control cabinet are often connected in multiple sections. In order to ensure the sealing of the connections, clamps with sealing rings are often required. During the production process of clamps with sealing rings, special grooves need to be stamped for installing sealing rings. Moreover, when producing clamps, batch production is often carried out, and the production must be uniform, that is, the position of the grooves formed each time should be roughly the same. In order to ensure that each groove is roughly the same, each clamp needs to be positioned before positioning, which is very troublesome. Utility Model Content

The threaded rod 4 is welded on the press 1, and the inside of the threaded sleeve 9 is threadedly connected to the surface of the threaded rod 4;

[0028] The clamping and positioning assembly is arranged on the press 1, and the clamping assembly includes two clamping plates 2, a special threaded rod 15, a gear 16, a motor gear 17 and a motor 18. The special threaded rod 15 rotates through a bracket outside the press 1, and the two clamping plates 2 are symmetrically threadedly connected to the special threaded rod 15. The thread of the special threaded rod 15 is half clockwise and half counterclockwise.

[0029] The threaded sleeve 9 rotates inside the connecting piece 12 , and the gear 13 is fixedly sleeved on the threaded sleeve 9 .

[0031] The electric telescopic rod 5 is mounted on the connecting piece 12 by means of screws, and the top rod 6 is mounted on the electric telescopic rod 5 by means of screws.

[0032] The top piece 14 is adhered to the top rod 6 , the surface of the top piece 14 is in contact with the mold 7 , and the surface of the top piece 14 is in contact with the surface of the clamp 3 .
