Device for detecting deformation of motor wave gasket and pull-down mechanism

Abstract

The invention relates to a device for detecting deformation of a motor wave gasket. The device comprises a lifting mechanism and a pull-down mechanism, wherein the lifting mechanism is used for fixinga motor through sliding engagement of a first top block assembly and a second top block assembly, and inaccurate motor detection caused by displacement of the lifting mechanism during the detection process is prevented; the pull-down mechanism comprises a tension sensor, a pull rod and a pull block, a tension is applied to a belt pulley of the motor by the pull block, the wave gasket is pressed,the tension is transferred to the tension sensor by the pull rod, and the state of the wave gasket in the motor can be detected. By the device, the stability of the detection device during the detection process is improved, and the motor detection result is more accurate; and meanwhile, the device can be suitably used for a motor production line and is convenient to operate and occupies a small 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...

Problems solved by technology

[0004] 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
