Auxiliary rotor core and end ring welding device

Abstract

The invention aims to provide an auxiliary rotor core and end ring welding device which can realize positioning between an end ring and a rotor core to facilitate welding of the end ring and the rotorcore. The device comprises a positioning sleeve, an annular pressing block and a fixing cover; an accommodating groove is formed in the positioning sleeve; a positioning column is arranged in the center of the accommodating groove; the fixing cover comprises a cover top; the circumferential outer edge of the cover top extends downwards to form an annular fixing part; threaded structures matched with each other are formed on the inner wall of the fixing part and the outer wall of the upper end of the positioning sleeve; a vertically-through yielding groove is formed in the cover top; when theannular pressing block is placed in the accommodating groove, the positioning column is sleeved with the rotor core, and the circumferential inner wall of the rotor core makes contact with the circumferential outer wall of the positioning column; and the fixing cover rotates on the positioning sleeve to enable the lower end surface of the cover top to abut against the upper end of the annular pressing block, so that the rotor core and the end ring are limited between the lower end surface of the annular pressing block and the bottom of the accommodating groove.

Description

technical field [0001] The invention relates to an auxiliary device for assembling parts of a motor, in particular to an auxiliary device for welding a rotor iron core and an end ring. Background technique [0002] The rotor core and the end ring need to be welded, but the existing positioning means between the rotor core and the end ring is poor, and it is difficult to realize the concentricity of the end ring and the rotor core, so that the position of the end ring after welding is different from the set position. deviation. Contents of the invention [0003] The purpose of the present invention is to provide a rotor core and end ring welding auxiliary device which can realize the positioning between the end ring and the rotor core, so as to facilitate the welding of the end ring and the rotor core. [0004] In order to achieve the above object, the present invention adopts the following technical solution: an auxiliary device for welding the rotor core and the end ring...
