AI Technical Summary

Technical Problem

Existing clamping devices are not effective at clamping irregularly shaped components, require an unstable clamping reference surface, and pose risks during the machining process.

Method used

The clamping device, which combines modules and bench vises, forms a cavity through the groove design on the left and right sides of the combined mold to constrain the irregular material with four degrees of freedom. The self-clamping structure of the irregular material's inclined surface ensures the stability of the reference surface.

Benefits of technology

It improves the stability of tapping irregularly shaped components, avoids mechanical defects such as non-perpendicular threads and large thread tolerances, and increases the yield rate.

Abstract

The application discloses a special clamping device for tapping of a special-shaped component and a tapping method, and relates to the technical field of special-shaped component tapping. The special clamping device comprises a module and a bench vice, the module comprises a left combined die and a right combined die, the left combined die and the right combined die are placed side by side in the jaw of the bench vice for clamping and limiting, recesses are arranged on the adjacent sides of the left combined die and the right combined die, two recesses are communicated to form a cavity for simultaneously accommodating two special-shaped materials and the cavity is upwardly open, and the parting surface in the left combined die and the right combined die clamps the special-shaped materials, and each cavity surface in the cavity serves as a constraint. The application realizes four-degree-of-freedom constraint of the module on the special-shaped materials by cooperation between the module and the bench vice and clamping of the module by the bench vice, and solves the problems that the existing clamping device has a poor clamping effect on special-shaped components, the clamping reference surface is unstable, and there are risks in the machining process.
