Assembling tool for electric clamp assembly

The invention relates to an assembling tool for an electric clamp assembly. The assembling tool comprises a working table, an automatic detection system, a clamping rotary device, a two-degree-of-freedom adjusting device and a tightening device, wherein the clamping rotary device is arranged on the upper end face of the left part of the working table; the two-degree-of-freedom adjusting device is arranged on the clamping rotary device; the tightening device is fixed on the two-degree-of-freedom adjusting device; the automatic detection system is arranged on the upper end face of the right part of the working table. By adopting the assembling tool, the problem of poor performance caused by thread assembly can be solved; the thread screwing accuracy is increased by adopting a torque-corner control method, namely, a bolt is screwed to a point to generate small torque, and is screwed by a specified corner from the point. By adopting the method, the axial pre-tightening accuracy of a bolt is high, great axial pre-tightening force of the bolt can be obtained, and the numerical value can be intensively distributed around an average value.
