Positioning clamp for thread machining of connecting rod of mechanical press

The utility model discloses a mechanical press connecting rod thread machining positioning clamp which structurally comprises an installation base, a limiting table, a positioning device and a connecting rod. When the mechanical press connecting rod thread machining positioning clamp is used, a clamping groove is fixedly connected to the installation base in an inserted mode through an inserting block, and the clamping groove and the limiting table are matched with each other to clamp the connecting rod in parallel; when the connecting rod penetrates and stretches into the clamping groove, the clamping abutting piece is fixed into the clamping groove through the two fixing plates in the connecting rod, and the connecting rod needing to be machined penetrates and stretches into the clamping abutting piece to be subjected to thread machining treatment. 本实用新型公开了一种机械压力机连杆螺纹加工定位夹具，其结构包括安装座、限位台、定位装置、连杆，本实用新型在进行使用时，卡槽通过插块固定插接在安装座上，卡槽与限位台互相配合可以来将连杆进行平行卡持，连杆在贯穿伸入卡槽时，其内部的两块固定板将卡持抵件固定在卡槽内部，将需要加工处理的连杆贯穿伸入卡持抵件来进行螺纹加工处理。
