Auxiliary positioning mechanism for mechanical parts

The utility model relates to the technical field of auxiliary positioning mechanisms, in particular to a mechanical part auxiliary positioning mechanism which comprises a fixing table, a sliding groove is formed in the middle of the upper surface of the fixing table, a first servo motor is fixedly connected to the middle of the upper end of the outer wall of the rear end of the fixing table, and the output end of the first servo motor is fixedly connected with a two-way threaded rod. And two threaded sleeves are arranged outside the two-way threaded rod in a sleeving manner. According to the auxiliary positioning mechanism for the mechanical part, the two-way threaded rod is driven to rotate through the first servo motor, so that the first mounting plate and the second mounting plate are driven to move relatively through the threaded sleeve, and the two ends of the part are clamped and positioned through the first clamping and positioning plate and the second clamping and positioning plate; and finally, an el
