AI Technical Summary

Technical Problem

The existing expansion machine device is difficult to clamp the frame-type closed-loop stator coil and the open coil at the same time, and the fixing problem of opening coils is not effectively solved.

Method used

A swelling machine clamping device is designed, through the cooperation of the lateral positioning mechanism and the longitudinal positioning mechanism, the simultaneous clamping and fixing of the nose end of the opening coil is achieved, including clamping side plates, transverse positioning mechanisms and longitudinal positioning mechanisms, and the clamping side plates are driven by the oil cylinder to move, and longitudinal positioning and clamping is achieved through the cooperation of the guide rod and the clamping plate.

Benefits of technology

The stable clamping of the open coil is achieved to ensure the fixation of the open coil during the expansion process. It can produce both closed-loop frame coils and open coils, solving the problem of misalignment and climbing at the nose of the double coil, and the equipment cost is low and the operation is reliable.

Abstract

The utility model discloses a clamping device of an expanding machine, which comprises clamping side plates arranged oppositely, and the clamping side plates are connected through a transverse positioning mechanism so as to provide transverse positioning for the nose end of an open coil; a longitudinal positioning mechanism is arranged on the inner wall of the clamping side plate, the longitudinal positioning mechanism is provided with a guide rod and clamping plates arranged at the two ends of the guide rod, and the clamping plates move in the same direction or in the opposite directions to longitudinally position, clamp and release the nose end of the open coil. Through cooperation of the transverse positioning mechanism and the longitudinal positioning mechanism, the nose end of the open coil is clamped in the transverse direction and the longitudinal direction at the same time, the problem that the open coil expanding machine cannot clamp and fix the coil is effectively solved, and expanding of the open coil is guaranteed.
