Description

Technical Field

[0001] This utility model belongs to the technical field of motor testing machines, and specifically relates to a motor positioning mechanism for a motor testing machine. Background Technology

[0002] An electric motor, as an electromechanical device, is an important equipment for converting electrical energy into mechanical energy. It operates based on the interaction between the magnetic field generated by an electric current passing through a conductor and an external magnetic field. This interaction causes the conductor to experience a force, thereby producing mechanical motion. In the crucial processes of motor manufacturing and production, motor testing is a vital step in comprehensively evaluating the assembly quality and technical performance of the motor.

[0003] Motor performance testing requires the motor to be firmly fixed in place. Since different motor sizes require different mounting plates, testing multiple motors requires a lot of time and manpower to change the mounting plates, resulting in a waste of human resources. To address this, a motor positioning mechanism for a motor testing machine is proposed. Utility Model Content

The chamber body is disposed on the side of the support plate, the fixing block is disposed on the side of the inner wall of the chamber, and the drive motor is disposed on the side of the inner wall of the chamber away from the fixing block. One end of the bidirectional lead screw is rotatably disposed inside the fixing block, and the other end of the bidirectional lead screw is fixedly connected to the drive motor. The lead screw nut is symmetrically sleeved on the bidirectional lead screw, and the lead screw nut is fixedly connected to the mounting plate.
