Jig

The invention provides a jig which is used for grinding points of machine tool stand column assembly and comprises a fixing plate used for being fixedly connected with a stand column and a rocker hinged to the fixing plate. The fixing plate extends outwards to form two hinge arms, the rocker is hinged between the two hinge arms through a hinge shaft, the upper section of the rocker is used for applying pulling force, and the lower section of the rocker is used for abutting against a bed body. The grinding point jig is designed according to the lever principle, easy grinding point operation is achieved, the working efficiency is improved, the labor cost is reduced, one-to-one actual matching grinding of the machine tool stand column and the machine tool body can be achieved through the grinding point jig, and the assembly precision is guaranteed. 本发明提供了一种治具，用于机床立柱装配的研点，包括用于固定连接立柱的固定板，以及铰接在固定板上的摇杆。固定板向外延伸出两个铰接臂，摇杆通过一铰接轴铰接在两个铰接臂之间，摇杆的上段用于施加拉力，下段用于抵靠床身。此研点治具设计利用杠杆原理，实现轻松研点作业，提升工作效率、降低劳动成本，利用此研点治具可实现机床立柱与床身一对一实配研磨
