Abstract

The invention discloses a noise testing device and method for motor production, and the device comprises a conveying belt which is located at the upper end of the ground, the left and right ends of the conveying belt are supported through supporting rods, rotating shaft bearings at the left and right ends of the conveying belt are connected with the supporting rods, the side edge of the conveying belt is provided with an inner supporting plate, the surface of the conveying belt is provided with a clamping groove, and the number of the supporting rods is four. The four supporting rods are welded to the upper portions of the front end and the rear end of the left side and the right side of the base plate correspondingly. According to the noise testing device for motor production and the testing method, a sliding plate is arranged, second motors on the left side and the right side of the lower end of the sliding plate drive lead screws to enable an upper measuring head to be attached to the side wall of a motor, and a lower measuring head above a lower end testing plate is matched to conduct electromagnetic noise testing at the middle section position of the motor; and then side test heads at the front end and the rear end of the test plate are attached to the front end and the rear end of the motor under the driving of a fourth push-pull rod to test ventilation noise and mechanical noise, so that multiple noises in the motor are tested, and more comprehensive test data are obtained.

Description

technical field [0001] The invention relates to the technical field of motor production, in particular to a noise testing device and a testing method for motor production. Background technique [0002] The motor is an electromagnetic device that achieves the conversion or transmission of electric energy through the law of electromagnetic induction. Generally, it can be divided into DC motors and AC motors according to the type of working power supply, and the function of the motor will be tested when the motor is in production. The noise is used as the motor. Important performance parameters, the following problems still exist when testing them, such as: [0003] The application number is: 202010554317.5, a noise detection device and its working method for motor load. When in use, according to its structural design, it passes through the workbench, detection device, hydraulic expansion machine, noise detection device, and clamping assembly. , connection frame, drive equipme...
