Testing system for sealing performance of motor and control method thereof

Abstract

The invention provides a testing system for the sealing performance of a motor. The system is composed of a material platform, sealing clamps, an air pump and a water storage tank. A motor is arrangedhorizontally on the material platform. The sealing clamps are respectively arranged at the two sides of the axial direction of the motor and include clamping plates and rotating driving units. The air pump has an air filling pipe that is connected to the inside of the motor by a clamp head. The water storage tank is arranged below one side of the material platform. In addition, the invention alsoprovides a control method of the testing system for the sealing performance of a motor. The method comprises the following steps that: (1), a motor is placed on a material platform; (2), a telescopicoil cylinder drives the clamp head to be compressed on the axial end surface of the motor; (3), the rotating driving units drive the motor to be immersed into the water storage tank; (4), the air pump refills the motor with air; and (5), the rotating driving units drive the motor to be taken out of water. The testing system and the control method have the following advantages: the two ends of themotor are compressed automatically by using the pressure generated by the oil cylinder, so that the tedious sealing and locking steps are reduced; the manpower is saved; the production time is reduced; and the automation degree is improved.

Description

technical field [0001] The invention relates to the technical field of motor production, in particular to a motor sealing test system and a control method thereof. Background technique [0002] The safety and waterproofing of electrical products in places where condensation occurs when the air humidity is high and the temperature is low has always been a difficult issue to solve. During the operation of the DC brushless external rotor motor, its electronic circuit board, motor winding, and bearings are directly connected to the high temperature. In contact with wet and low temperature air, dew condensation on the surface is inevitable, which leads to safety accidents. [0003] Before the motor leaves the factory, the sealing performance test must be carried out on the motor, and the motor can only leave the factory if it meets the standard. But in the prior art, usually comprise high-pressure gas, water container and ventilation pipe. The motor is sealed and placed in the ...

[0002] The safety and waterproofing of electrical products in places where condensation occurs when the air humidity is high and the temperature is low has always been a difficult problem to solve. During the operation of the DC brushless external rotor motor, its electronic circuit board, motor winding, and bearings are directly connected to the high temperature. In contact with wet and low temperature air, dew condensation on the surface is inevitable, which leads to safety accidents

[0004] In production, the two ends of the motor are generally sealed manually, and then the motor is hoisted by the crane to enter the water. This method is inefficient and requires a lot of labor for the workers. Moreover, the crane is used for hoisting, which has potential safety hazards and is not suitable for mass production.
