Automatic shaft riveting machine and application method thereof

Abstract

The invention discloses an automatic shaft riveting machine and an application method thereof. The automatic shaft riveting machine comprises a shaft riveting machine body, wherein a punching machine is arranged on the shaft riveting machine body; a guide block is fixed to one side of the shaft riveting machine body; a punching head is arranged on the inner side of the guide block; the output end of the punching machine is fixedly connected with the punching head; a mounting block is fixed to the inner side of the shaft riveting machine body through a bolt; a sliding block is connected to the inner side of the mounting block through a sliding groove; a first telescopic cylinder is fixed to the other side of the shaft riveting machine body; and the output end of the first telescopic cylinder is connected with the sliding block in a matched mode. Through the arrangement of the riveting jig body, the punching head, a positioning column, an air connecting opening, the sliding block, an ejector pin and a second telescopic cylinder, a center shaft can be conveniently and well riveted to a motor galvanized plate, so that the problem that the center shaft and a motor pole claw are not concentric when a motor shaft is installed is solved, and the out-of-tolerance of the center shaft and the center of the motor caused by secondary processing of a motor galvanized sheet preset hole and a shaft positioning position is avoided.

Description

technical field [0001] The invention belongs to the technical field of motor shaft riveting, and in particular relates to an automatic shaft riveting machine and a using method thereof. Background technique [0002] The motor (commonly known as "motor") refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. The motor is represented by the letter M (the old standard uses D) in the circuit. Its main function is to generate driving torque. As As the power source of 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. During the production process of the motor, a preset hole is usually punched on the galvanized plate of the motor. , and then the central shaft is pressed into the prefabricated hole for riveting. [0003] When the existing riveting shaft of the ...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide an automatic shaft riveting machine and its use method to solve the problem of the secondary processing of the preset hole of the motor galvanized plate and the positioning position of the shaft during the processing of the existing motor shaft riveting proposed in the above-mentioned background technology. , there is a certain error, so the concentricity and perpendicularity have been poor. For motor production, the concentricity of the shaft and the claw directly affects the torque of the motor. When the concentricity is poor, the output torque of the motor is small, and it affects the use of the motor. It is not convenient to improve the concentric effect of the central shaft and pole claws
