In the motor assembly process, the quality of the wave gasket directly affects the quality of the motor assembly. For this reason, a wave gasket inspection equipment is specially set up in the assembly process to detect whether the wave gasket in the motor is missing or installed. , the commonly used detection method is to take a visual photo before the end cover is assembled or use a displacement sensor to measure the displacement with a constant pressure to detect the wave gasket, but this method ignores the influence of the magnetic field force of the rotor and stator on the wave gasket, so it cannot Completely simulates the state of the wave pad in the bearing chamber very well, but the accuracy of the test results is low

The invention relates to a device for detecting the deformation of a motor wave pad, which includes a lifting mechanism and a pull-down mechanism. The displacement of the lifting mechanism causes inaccurate detection of the motor; the pull-down mechanism includes a tension sensor, a pull rod and a pull block, and the pulling force is applied to the pulley of the motor through the pull block, the wave gasket is pressed, and the pulling force is transmitted to the tension sensor through the pull rod. The state of the wave gasket in the motor can be detected. The device improves the stability of the detection device during the detection process, and the motor detection result is more accurate. At the same time, the device can be applied to the motor production line, and is easy to operate and occupies less space.
Description
technical field [0001] The invention relates to the technical field of motor detection, in particular to a device and a pull-down mechanism for detecting the deformation of a motor wave pad. Background technique [0002] Due to the radial clearance of the bearing in the motor, the rotor will receive an axial electromagnetic force during the operation of the motor, and axial vibration and noise will be generated during the operation of the motor. In order to solve the axial vibration and noise of the motor, it is necessary to apply a certain axial preload to the motor bearing to adjust the radial clearance of the bearing, provide a resistance to the axial electromagnetic force in the rotor, and suppress the vibration and noise of the motor. [0003] The full name of the wave pad is a wave gasket, also known as a wave gasket, which is a regular wavy circular sheet. It is generally used to prevent loosening and buffer impact. It needs to have good elasticity and impact resista...
