Rivet pressing machine for end cover

Abstract

The invention relates to the field of servo motor assembling and machining equipment, in particular to a rivet pressing machine for an end cover. The rivet pressing machine comprises a servo motor, a lifting mechanism, an upper mold and a lower mold. The servo motor drives the upper mold to rise and fall by driving the lifting mechanism. In the falling process of the upper mold, the end cover placed on the lower mold is subjected to rivet pressing. According to the rivet pressing machine for the end cover, compared with the prior art, the servo motor drives the upper mold to rise and fall by driving the lifting mechanism; in the falling process of the upper mold, the end cover placed on the lower mold is subjected to rivet pressing, and the end cover and a stator are automatically connected in a pressed mode; precise control is achieved by adjusting a mold manually, and the product quality is improved; moreover, the noise occurrence rate of bearings is reduced, and operating of the mechanism is stable; the potential safety hazards due to the fact that a cylinder body of an existing air cylinder type rivet pressing machine for the end cover or an existing oil cylinder type rivet pressing machine for the end cover falls off and flies off are effectively avoided, and the safe usability is improved.

Description

technical field [0001] The invention relates to the field of motor assembly and processing equipment, in particular to an end cover riveting press. Background technique [0002] At present, in the crimping operation of the stator end cover of the motor, an oil press or an air press is generally used for the end cover crimping. Among them, the hydraulic press is a kind of hydraulic press that circulates the hydraulic oil in the oil tank through the check valve to make the oil cylinder / piston circulate and do work, so as to complete certain mechanical actions as a productive force. The hydraulic press uses special hydraulic oil as the working medium and the hydraulic pump as the power source. The force of the pump makes the hydraulic oil enter the cylinder / piston through the hydraulic pipeline. Under the action of high-pressure oil, the cylinder moves to complete the pressing process. device of. Pneumatic press is also called pneumatic stamping machine. It uses the high-pres...

Problems solved by technology

[0003] But above-mentioned oil press and air press have oil pressure, air pressure in the process of pressing end cover and cause unstable product quality, and the cylinder body of air press and oil press is easy to come off and fly out, causes certain potential safety hazard; Meanwhile, in manual During the mold adjustment process, the pressing origin is not easy to control, and phenomena such as undervoltage, overvoltage or poor concentricity occur, resulting in the problem of high bearing noise

[0004] In view of the above problems, we need an end cap riveting machine to solve the problem of unstable product quality due to poor oil pressure and air pressure in the existing end cap riveting press, and the cylinder body of the air press and hydraulic machine is easy to fall off and fly out. It causes certain safety hazards, and it is not easy to control the pressing origin during the manual mold adjustment process, resulting in undervoltage, overvoltage or poor concentricity, which leads to the problem of high bearing noise
