Auxiliary detection tool

The utility model provides an auxiliary detection tool. The auxiliary detection tool comprises a plurality of coupling jigs and a crank, the coupling jigs are used for being installed at the shaft ends of lead screws of different types respectively so that the dial indicator can be erected to detect the precision of the motor base. When one coupling jig is detachably connected with the crank, thecoupling jig is used for rotating the Z-axis lead screw or the Y-axis lead screw so as to assist in detecting the perpendicularity between the main shaft and the workbench; the crank comprises a rotating arm, a connecting rod and a handle; the rotating arm and the handle are arranged at the two ends of the connecting rod respectively. The coupling jig is in a stepped shaft shape, the small-diameter part of the coupling jig is used for being detachably connected with the rotating arm, and therefore cost is low. 本实用新型提供一种辅助检测工具，包括若干联轴治具、一个摇把；各联轴治具分别用于安装在不同型号丝杆的轴端，以架千分表检测电机座的精度；一个联轴治具和摇把可拆卸连接时，用于旋转Z轴丝杆或Y轴丝杆，以辅助检测主轴和工作台间的
