A positioning pin is fixed at the center of the top surface of the assembly plate. A chute is opened at the edge of the top surface of the assembly plate. A claw is provided in the chute. The number of claws is not less than three and is rotationally symmetrically distributed. A limiting block is fixed on one side of the claw. A connecting rod is provided at the bottom of the limiting block. One end of the connecting rod is rotatably connected to the limiting block, and the other end of the connecting rod is connected to a driving component.

[0006] Preferably, the driving component includes a motor, a threaded shaft and a displacement block. The motor is arranged on the bottom plate and is located directly below the assembly plate. A threaded shaft is fixed on the output end of the motor.

[0007] Preferably, the threaded shaft is vertically arranged, and a displacement block is sleeved outside the threaded shaft. The displacement block is in threaded cooperation with the threaded shaft.

[0008] Preferably, grooves corresponding to the number of connecting rods are provided on the outer side wall of the displacement block. A rotating shaft is provided in the groove. The connecting rod penetrates into the groove and is rotatably connected to the displacement block through the rotating shaft.

[0012] In the present utility model, the positioning pin penetrates into the through hole at the center of the first mass fitting and places the first mass fitting on the assembly plate. The motor rotates the threaded shaft to drive the displacement block to move downward. The displacement block pulls the limiting block through the connecting rod, causing the limiting block to move synchronously in the chute towards the positioning pin, thereby driving the claw to move towards the first mass fitting until the ratchet teeth mesh with the friction teeth of the first mass, so as to position the first mass fitting. Subsequently, the subsequent fitting installation penetrates the positioning pin in sequence and is welded to the first mass fitting. The overall positioning structure is simple, the operation is convenient, and the centering accuracy of the fitting is high. BRIEF DESCRIPTION OF THE DRAWINGS
