Assembling tool for electric caliper assembly

The utility model relates to an assembling tool for an electric caliper assembly. The assembling tool comprises a working table plate, an automatic detection system, a clamping and rotating device, a two-degrees-of-freedom regulation device and a screwing device. The clamping and rotating device is installed on the upper end face of the left of the working table plate. The two-degrees-of-freedom regulation device is installed on the clamping and rotating device. The screwing device is fixed to the two-degrees-of-freedom regulation device. The automatic detection system is installed on the upper end face of the right of the working table plate. According to the assembling tool, the problem of poor performance caused by thread assembly can be solved, and the screwing accuracy of threads is improved by the adoption of a torque-rotation angle control method; in other words, the control method comprises the steps that firstly, bolts are screwed to small torque, and then the bolts are screwed by a regulated rotation angle from the point. By the adoption of the method, the axial pre-tightening force accuracy of the bolts is high, large axial pre-tightening force of the bolts can be obtained, and the value of the axial pre-tightening force can be distributed adjacent to an average value in a centralized mode.
