Rivet button device of motor end cover

Abstract

A rivet button device of a motor end cover comprises a base, a locating ring, a compression cylinder and rivet button cylinders. The locating ring is arranged on the base, and the compression cylinder which is supported by a bearing post and a bearing plate and an end cover compression sleeve which is connected with the compression cylinder are arranged above the locating ring. The four rivet button cylinders are evenly arranged on the outer circle of the locating ring, each rivet button cylinder is connected with a rivet button shovel through a connector, and the rivet button shovels are arranged in corresponding rivet button grooves in the circumference of the locating ring. A nylon pad is mounted in the locating ring, and a locating ring notch is further formed in the circumference of the locating ring. The rivet button device of the motor end cover is simple in structure and convenient to operate, a motor is placed in the device, the motor can be fixed through the compression cylinder, under the action of the rivet button cylinders, rear cover rivet button protrusions and front cover rivet button holes of the motor can be buckled in a riveting mode through the rivet button shovels, and accordingly a front cover, a rear cover, stator embedded parts and rotor pressing parts can be fastened together, wherein the stator embedded parts and the rotor pressing parts are placed in an inner cavity of the front cover and an inner cavity of the rear cover. Materials are saved, motor assembling efficiency is improved, the coaxiality of the motor after assembly is guaranteed, electromagnetic air gaps of the motor are even, and noise is small.

Description

technical field [0001] The invention relates to the field of motors, in particular to a riveting device for a motor end cover. Background technique [0002] A large number of motors are used in household appliances. The traditional motor assembly method is mainly fastened by screws. The screws are passed through the end cover holes, and then put on flat washers, spring washers, and nuts. The dimensions of these four parts They are relatively small, and it is extremely difficult to assemble the motor. Each motor needs to be installed with 4 sets of screws, flat washers, spring washers, and nuts, and it is easy to miss one of the screws, flat washers, spring washers, and nuts. The operation is complicated , low work efficiency, waste a lot of manpower and financial resources. At present, there are 3-5 people on the motor assembly line for assembling screws, flat washers, spring washers, and nuts. Switching to the end cover rivet can save 4 processes, and use the rivet groove ...

AI Technical Summary

Problems solved by technology

[0003] In the traditional motor assembly operation method, each set of screws, flat washers, spring washers, and nuts needs to be tightened with an electric wrench. Because it needs to be tightened manually by a group, the force is inconsistent, so the coaxiality of the tightened motor is not good. Use Loud noise

Not only pollute the environment, but also greatly reduce the service life of the motor
