Rough polishing device for edge of motor end cover cake

Abstract

The invention discloses a rough polishing device for the edge of a motor end cover cake. The rough polishing device comprises a device body. A base is arranged at the bottom of the device body. A fixing sleeve is arranged above the base. A containing groove is formed in the base, and a motor is arranged on the inner side of the containing groove. The device body is provided with a rotating rod, and a bottom plate is arranged on the top of the rotating rod. A connecting seat is arranged at the middle position of the bottom plate, and a carrying plate is arranged above the bottom plate. A permanent magnet is arranged on the upper end face of the carrying plate, a rotating die is arranged on the device body, and a grinding wheel is arranged on the inner wall of the rotating die. The rough polishing device is simple in structure and convenient to use, preliminary polishing is conducted on the edge of the cake under the effect of the device body, the phenomenon that burr trimmings exist, and consequently the hands of operators are pulled to be injured is avoided, and the safety performance is improved; and in addition, fixing of the cake is very convenient when the device body works, no special fastening equipment needs to be used, trouble operation is reduced, the work efficiency is effectively improved, the product takt is accelerated, and practicability is high.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a device for roughly grinding the edge of a motor end cover circular cake. Background technique [0002] A motor is an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. In the circuit, it is represented by the letter M (the old standard is D). Its main function is to generate driving torque as a power source for electrical appliances or various machinery. The generator is represented by the letter G in the circuit. Its main function is to convert mechanical energy into electrical energy. At present, the most commonly used is to use heat energy, water energy, etc. to drive the rotor of the generator to generate electricity. [0003] The end cover is a back cover installed behind the casing of the motor, commonly known as "end cover". Whether the end cover is good or bad directly affects the quality of the ...

AI Technical Summary

Problems solved by technology

[0005] When the end cover is produced, the end cover is firstly made into cakes, and then the round cake is stamped into the end cover. However, there will be a problem during the operation of the cake, that is, the edge of the round cake is being punched. After the production is finished, there will be a lot of burrs and flashes, so it is necessary to carry out preliminary grinding on the round cake, otherwise it will scratch the hands of the operator, and the existing grinding method is that the staff use sandpaper to grind manually, and the work The efficiency is very low, and it is necessary to use a special clamp to clamp the round cake when grinding, which is very cumbersome to operate, delays time, and leads to a slow production cycle
