A device for finishing aluminum casting shell of electric motor

Abstract

The invention relates to the field of motor manufacturing, in particular to a device for finishing aluminum casting shells of electric motors, which includes a main bracket, one side of the main bracket is rotatably connected to a No. Both ends of one side of the No. 1 rotating shaft are provided with mounting blocks, and a No. 1 hydraulic cylinder is arranged in the mounting block. The installation direction of the No. 1 hydraulic cylinder in the two mounting blocks is opposite to each other. The output end of the No. 1 hydraulic cylinder runs through the mounting block And a pressure rod is fixedly installed, and the end of the pressure rod away from the No. 1 hydraulic cylinder is provided with a conical structure pressure block, and the end of the pressure block away from the pressure rod is provided with an insertion rod, and the insertion rods on the two pressure blocks are alternately distributed, and the insertion The end of the rod away from the pressure block is provided with an adjustment groove. The invention can quickly clamp and fix the molded aluminum casting shell of the motor, and can adjust according to the height of the aluminum casting shell of the motor.

Description

technical field [0001] The invention relates to the field of motor manufacturing, in particular to a device for finishing the aluminum casting shell of a motor. Background technique [0002] The motor is a device that converts electrical energy into mechanical energy; it uses a energized coil to generate a rotating magnetic field and acts on the rotor to form a magnetoelectric force; the motor is divided into DC motor and AC motor according to the power supply used. The motor in the power system is large Part of it is an AC motor, and it can also be a synchronous motor or an asynchronous motor. [0003] At present, in order to improve the heat dissipation effect of the motor and reduce the weight of the motor, aluminum casting shells are used. Most of the conventional aluminum casting shells of electric motors are molded by integral casting. After the shell is formed, a large number of burrs generally remain on the surface, which is relatively rough. It is not conducive to ...

AI Technical Summary

Problems solved by technology

[0003] At present, in order to improve the heat dissipation effect of the motor and reduce the weight of the motor, aluminum casting shells are used. Most of the conventional aluminum casting shells of electric motors are molded by integral casting. After the shell is formed, a large number of burrs generally remain on the surface, which is relatively rough. It is not conducive to spraying protective coatings, so the shell needs to be polished, and there are generally a large number of cooling fins on the outer wall of the conventional motor shell, and the specifications are inconsistent. Grinding, which greatly reduces the finishing efficiency of the motor casing, and the conventional grinding device can only be used for finishing the aluminum casting casing of a single size motor, and the function is relatively single. At the same time, when installing the aluminum casting casing of the motor, manual labor is required. Manual alignment and fixing are time-consuming and labor-intensive, increasing labor costs, which brings inconvenience to the finishing of the aluminum casting housing of the motor
