Assembly type prefabricated part auxiliary positioning device

The utility model belongs to the technical field of prefabricated part positioning, and particularly relates to an assembly type prefabricated part auxiliary positioning device which comprises a fixing block, rotating arms are symmetrically and rotationally connected to the two sides of the outer portion of the fixing block, a first threaded rod is in threaded connection with one side of the interior of each rotating arm, and a push plate is rotationally connected to one end of each first threaded rod. Limiting frames are arranged on the two sides of the outer portion of the fixing block. The utility model provides an auxiliary positioning device for an assembly type prefabricated part, and solves the problems that the existing prefabricated part is generally large in size and different in height and width during installation, so that stable positioning is inconvenient, and the prefabricated part shakes or inclines due to overlarge external force during assembly, so that the prefabricated part cannot be stabl
