SPECIAL-SHAPED PART CLAMPING DEVICE

A special-shaped part clamping device comprises a clamping device, a base and a support frame, wherein the support frame is symmetrically fixed on the base, and the clamping devices are respectively oppositely fixed at the upper ends of the support frame. The clamping device comprises a mounting pipe, a jacking component, a locking component, an adjusting component and an elastic clamping component. According to the invention, the backstop wedge is fixedly clamped between two elastic clamping components by using the elastic clamping component, so that the end of the elastic clamping component is in contact with the irregular surface of the backstop wedge, the jacking component is rotated, the jacking component is abutted against the elastic clamping component, and the jacking component is locked by the locking component, so that the jacking component does not displace, so that the end of the elastic clamping component can be closely contacted with the irregular surface of the backstop wedge, and the backstop wedge is firmly clamped. When in use, the backstop wedges with different shapes and diameters can be clamped and fixed, which reduces the frequency of replacing clamping fixture, improves the production efficiency and reduces the input cost.
