A kind of motor rotor processing technology

Abstract

The invention discloses a motor rotor processing technology and belongs to the technical field of machining. The motor rotor processing technology has the advantages of changing the pre-mounting states of silicon steel sheets by means of heat and being convenient to mount the silicon steel sheets. The technical scheme is as follows: the motor rotor processing technology comprises the following steps: S1, previous preparation: cleaning a silicon steel sheet roll and fixing the silicon steel sheet roll to a leveling machine; S2, leveling of the silicon steel sheet roll: passing the silicon steelsheets out of the silicon steel sheet roll to pass the leveling machine and extruding and leveling two sides of the silicon steel sheets by the leveling machine; S3, heating of two faces of the silicon steel sheet roll by an annular difference value: annularly heating two side faces in same positions of the silicon steel sheets through an annular heating plate, wherein the heating temperatures ontwo faces of the silicon steel sheets has a temperature difference; S4, stamping of the silicon steel sheet roll: carrying out punch forming of the heating positions of the silicon steel sheets; andS5, mounting of the silicon steel sheets: mounting the arc-shaped silicon steel sheets in a motor shaft successively and homonymously and extruding and leveling the silicon steel sheets by means of abalancing weight.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a motor rotor processing technology. Background technique [0002] The motor rotor is the rotating part in the motor. The motor is composed of two parts: the rotor and the stator. It is a conversion device used to realize electrical energy and mechanical energy and mechanical energy and electrical energy. [0003] The motor rotor is formed by stacking stamped silicon steel sheets into the motor shaft in turn, then winding copper wire, and fixing the brushes to form the motor rotor assembly. [0004] The Chinese patent with the publication number CN101633018A discloses the stamping process of the stator and rotor of the motor. It forms a ring-shaped rotor by stamping the silicon steel sheet, and then puts it into the motor shaft. However, the silicon steel sheet after stamping is not smooth.

[0004] The Chinese patent with the publication number CN101633018A discloses the stamping process of the stator and rotor of the motor. It forms a ring-shaped rotor by stamping the silicon steel sheet, and then puts it into the motor shaft. However, the silicon steel sheet after stamping is not smooth. Silicon steel sheets are also prone to large deformation during the process, resulting in large gaps when superimposed, and it is difficult to keep flat after extrusion, which makes it impossible to use in precision motors.
