Description

Technical Field

[0001] The invention relates to the technical field of motor base processing, in particular to a motor base processing device. Background Art

[0002] The outer shell of the motor stator is called the base, which is used to fix the commutator poles, main magnetic poles and end covers, as well as to support and fix the entire motor. During the processing of the motor base, the flat steel plate is first rolled into a cylinder, and then the heat dissipation fins on the outside of the motor base are welded to the outside of the cylinder by machine welding. Subsequently, the base is hoisted to the scraping machine, and the inner hole clamping mechanism of the scraping machine is used to expand the inside of the base. Subsequently, foreign matter generated by welding between the heat dissipation fins of the motor base is manually scraped off, and then the motor base is hoisted to the coating equipment by the hoisting equipment, and the motor base is subjected to basic coating treatment. The motor base with the coating completed is moved to the assembly link through the assembly line for subsequent assembly.

[0003] However, in the production process of the motor base, although the inner hole clamping mechanism on the scraping machine is used to expand the outer side of the motor, during the process of expanding the motor base, the inner diameter and outer diameter of the motor base are deformed, which further easily leads to the deformation of the heat sink fins. The deformation of the heat sink fins is manifested as bending of the shape of the heat sink fins, resulting in a reduction in the heat sink area of ​​the heat sink fins or obstruction of the heat sink path, thereby reducing the heat dissipation effect of the motor.
