AI Technical Summary

Technical Problem

Traditional jigs for machining small beams lack positioning accuracy and have poor clamping stability, making it difficult to adapt to the irregular structure and material characteristics of electric bicycle beams, thus affecting processing quality and safety.

Method used

A small beam clamp was designed, which uses an inclined surface structure and a rubber clamping block in the clamp seat. The inclined surface self-locking effect enhances the clamping force, the protrusion restricts lateral displacement, and the arc-shaped part reduces stress concentration. The detachable locking block improves the installation efficiency.

Benefits of technology

It improves the positioning accuracy and clamping stability of small beam machining, reduces hole deviation and material damage, and enhances machining quality and safety.

Abstract

本实用新型涉及一种小梁夹具，包括夹具座、压紧块和锁紧块，所述夹具座上开设凹槽，所述凹槽内一端设置第一斜面，所述凹槽内另一端设置第二斜面，所述凹槽内两侧分别设置有突出部，当小梁置于所述凹槽内时，所述压紧块放置在小梁内，所述锁紧块设置在所述压紧块上方，所述锁紧块与所述夹具座可拆卸连接。本实用新型的小梁夹具通过夹具座凹槽内的第一斜面和第二斜面配合压紧块，利用斜面的自锁效应增强夹持力，确保小梁在受力时不会滑移或松动。同时凹槽两侧的突出部限制小梁的横向位移，提高稳定性。
