Abstract

The invention specifically provides a clamp for a thin-walled part with a lightening hole. The problem that an existing thin-walled part with the lightening hole easily deforms, influences the production efficiency and enables waste to be severe during machining is solved. The clamp comprises a rectangular connecting base plate connected with each hydraulic chuck main claw, wherein the middle of the connecting base plate is provided with an adjusting hole, the end face of one end of the connecting base plate is provided with a stepped hole communicated with and perpendicular to the adjusting hole, a column-shaped chuck rod penetrates the adjusting hole, the side wall of one end of the chuck rod is provided with a key groove opposite to the position of the stepped hole, the side wall of the other end of the chuck rod is provided with a clamping alveolar socket, a positioning screw in threaded connection with the stepped hole and in contact with the bottom end of the key groove is screwed in the stepped hole, a positioning block is arranged under the clamping alveolar socket and provided with a stepped hole I, and a fastening screw connected with the connecting base plate is screwed in the stepped hole I. The clamp enables the part deformation possibility to be reduced by higher than 90%, and the production, research and development input cost is reduced.

Description

technical field [0001] The invention relates to an auxiliary device for machining of auto parts, in particular to a fixture for thin-walled parts with weight-reducing holes. Background technique [0002] The auto parts machining industry is facing small profit margins, and customers have higher and higher requirements for products. Thin-walled parts with weight-reducing holes are a new direction that machining companies are constantly exploring. [0003] Existing processing of thin-walled parts with weight-reducing holes mostly uses hydraulic clamping devices to clamp the outside for processing. During the processing, the deformation probability of parts is relatively high, and the utilization rate is low, which affects production efficiency and causes cost. waste. Contents of the invention [0004] In order to solve the problem that the existing thin-walled parts with weight-reducing holes are easily deformed, affect production efficiency and cause serious waste during p...
