Auxiliary positioning clamp for gear machining

The utility model discloses an auxiliary positioning fixture for gear processing, which comprises a chuck, a pull rod, a gland and a linear motion driving element, the chuck is of a hollow structure, the pull rod is arranged in the chuck, one end of the pull rod is fixedly connected with the gland, and the other end of the pull rod is fixedly connected with the linear motion driving element. According to the auxiliary positioning clamp for gear machining, when a gear is repeatedly clamped for multiple times, the clamping positions of each time are the same, and therefore the machining precision is guaranteed. And meanwhile, the gear can be prevented from being reversely installed through the positioning pin. 本实用新型公开了一种齿轮加工辅助定位夹具，包括：夹头，拉杆，压盖，直线运动驱动元件，所述夹头为中空结构，所述拉杆在夹头内部，所述拉杆的一端与压盖固定连接，另一端与直线运动驱动元件固定连接。本实用新型提供了一种齿轮加工辅助定位夹具，齿轮在多次重复装夹时，每次装夹的位置都相同，从而保证加工的精度。同时通过定位销能够防止齿轮装反的情况出现。
