Servo automatic press equipment for assembling motor stator and rotor and assembly method thereof

Abstract

The invention discloses a servo automatic press equipment for assembling a motor stator and a rotor and an assembly method thereof. The press equipment includes a housing assembly, a pressing assembly installed on the housing assembly and a control system, and the The control system includes a servo driver and an instruction input unit, the press assembly includes a stator fixing module, a rotor press module and a servo drive module; the servo drive module includes a screw, a first servo motor, a pressure sensor, and the first The servo motor drives the rotor pressing module to reciprocate relative to the stator fixing module through a screw; after the stator to be installed is fixed on the base of the stator fixing module and the rotor pressing module fixes the rotor to be installed, The servo driver drives the first servo motor to drive the screw to rotate, so that the rotor to be installed is approached to the stator to be installed and press-fitted in place, and at the same time, the press-fitting applied to the rotor press-fitting module is controlled according to the feedback data of the pressure sensor. pressure.

Description

technical field [0001] The invention relates to testing equipment used in the production process of motors, in particular to an assembly equipment capable of realizing controllable pressing pressure and stroke in the assembly process of a stator and a rotor and an assembly method applied to the equipment. Background technique [0002] Motor (English: Electric machinery, 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. 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...

AI Technical Summary

Problems solved by technology

Since the stator and the rotor have opposite magnetic fields, and there is a small installation gap between the stator and the rotor, it is difficult to perform manual positioning, resulting in poor positioning accuracy of the stator and rotor during manual assembly, and assembly The pressure and stroke are not easy to control accurately, and it is easy to cause bearing damage and is not easy to detect. Most of the bearing damage can only be found during use, resulting in a high failure rate of the servo motor, many customer complaints, and low assembly efficiency, which cannot meet mass production. requirements
