Welding equipment and method for motor copper rotors

Abstract

The invention discloses welding equipment for motor copper rotors. The welding equipment comprises a base, a fixed base and a welding mechanism; the fixed base is mounted on the base, and is used forpositioning and fixing iron cores and copper bar combination bodies; the welding mechanism comprises a rotating driver, a main shafts, a chuck and a linear driver; the tail end of the main shaft is connected with the chuck; the chuck is used for fixing end rings of a motor; the rotating driver is connected with the main shaft, and drives the main shaft to rotate; and the linear driver drives the main shaft and the chuck to linearly move relative to the iron cores and copper bar combination bodies. The welding equipment mainly adopts an inertia rotating friction welding process to realize welding of the end rings of the motor, copper bars and positioning ring, can realize high-efficiency, high-quality and high-stability welding of copper rotor end rings, is suitable for large-batch weldingproduction of the copper rotors, can select different material combinations of the end rings and the positioning rings, greatly improves the design flexibility of the copper rotors, and can further improve the usability of the copper rotors through optimized material combinations.

Description

technical field [0001] The invention relates to the field of welding, in particular to a welding equipment and method for a copper rotor of a motor. Background technique [0002] figure 1 with figure 2 It is the structural diagram and exploded view of the copper rotor of the motor in the prior art. The copper rotor includes iron core, copper bar, positioning ring and end ring; the installation steps are: first insert the copper bar into the prefabricated groove of the iron core, and then use the left and right positioning rings Position and fix the part protruding from the iron core at both ends of the copper bar, and finally weld the left and right end rings to the copper bar and the left and right positioning rings. [0003] At present, the welding process between the left and right end rings of the copper rotor and the copper strips is mainly by brazing process, the operation process is complicated, the surface treatment of the welding workpiece is very demanding, the ...

AI Technical Summary

Problems solved by technology

[0003] At present, the welding process between the left and right end rings of the copper rotor and the copper bars is mainly performed by the brazing process, which is complicated in operation, requires high surface treatment of the welding workpiece, lacks effective control of the welding effect, and has poor consistency of the copper rotor after welding.
