Abstract

The invention discloses a horizontal side-arranged tensioning device for motor rotor conducting bars, which comprises a machine body base, a supporting and rotating mechanism, axial movement mechanisms, rolling mechanisms and an auxiliary pressing mechanism, wherein the supporting and rotating mechanisms are arranged at two sides of the surface of the machine body base and used for horizontally supporting and circumferentially rotating a rotor workpiece, the axial movement mechanism is used for driving the supporting and rotating mechanisms to drive the rotor workpiece to move in the axial direction in a reciprocating mode, the rolling mechanisms are erected on the machine body base, positioned at two radial sides of the rotor workpiece and used for being tightly abutted against each conducting bar on the rotor workpiece so as to enable the conducting bars to be tensioned in iron core grooves through reciprocating rolling, and the auxiliary pressing mechanism is erected on the machinebody base and used for pressing the surface of the rotor workpiece so as to prevent the rotor workpiece from generating radial or axial runout in the reciprocating movement process. The device disclosed by the invention can improve the tensioning efficiency of the motor rotor conducting bars, prevent the rotor from generating axial or radial runout, ensure the uniform and consistent tensioning degree and uniform and continuous tensioning deformation of each conducting bar and eliminate the potential safety hazards caused by a tensioning punch in the tensioning operation process.

Description

technical field

[0001] The invention relates to the technical field of motors, in particular to a horizontal side tensioning device for a motor rotor guide bar. Background technique

[0002] With the development of China's machinery industry, more and more machinery and equipment have been widely used.

[0003] The occasions involving mechanical rotation often need to be realized by means of electric motors. Three-phase asynchronous motors are a type of induction motors, which are powered by simultaneous access to 380V three-phase AC current. The squirrel-cage motor is a kind of three-phase asynchronous motor. The squirrel-cage rotor is the rotating part of the squirrel-cage motor. Generally, copper or aluminum rotor coils are cast in the cage-shaped slots on the rotor core.

[0004] The copper guide bar of the squirrel cage rotor of the AC motor needs to be tightened and fixed in the rotor core slot to prevent the axial displacement of the copper guide bar during the manuf...
