Description

Technical Field

[0001] The utility model relates to the technical field of test fixtures, and in particular to a motor load aging test fixture. Background Art

[0002] The primary function of a motor is to generate driving torque. As a power source for electrical appliances and various machinery, motors are currently used in a wide range of applications. Motor manufacturers require motor aging testing during the production process. This testing primarily involves rotating the motor through power supply to assess its condition. Motors undergo extensive testing before shipment, and motor aging testing is a key component. During testing, the motor under test cannot be allowed to idle, so a load is applied to simulate the load conditions experienced in actual use. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a motor load aging test fixture, which is convenient for applying a load to the motor for aging testing.

[0004] The technical solution of the present utility model is: a motor load aging test fixture, comprising a base plate, a sliding module arranged on the base plate, a clamping block slidably connected to the sliding module, and a rotation test module, the rotation test module is horizontally arranged on the base plate through a mounting plate, the clamping block is arranged opposite to the test module through a connecting block, the clamping block is adapted to the motor, the test module comprises a hysteresis, a coupling connected to the hysteresis and a positioning block arranged at the end of the coupling, the hysteresis is electrically connected to a power supply, the positioning block is adapted to the surface of the motor, the clamping block limits the motor and realizes linear movement toward the rotation test module for testing by moving on the sliding module.

[0005] As can be seen from the above scheme, the test module is used to drive the motor to perform a rotation test through the coupling. The hysteresis device is used to generate torque after power is applied to simulate the effect of the motor with load. The motor load is adjusted by adjusting the magnitude of the hysteresis device's damping force, which facilitates the expansion of the motor's load aging test range. The hysteresis device occupies less space and volume, which saves equipment resources and improves test efficiency. The positioning block positions the motor surface through the positioning pins. The clamping block is used to limit and clamp the motor. The sliding module is used to drive the motor to perform linear motion to move the motor closer to or away from the test module. The sliding module drives the motor to move closer to the test module to achieve limit, which facilitates the adjustment and limit of motors of different widths to prevent loosening from affecting the test results. The hysteresis device is used to apply a load to the motor after power is applied. The coupling is used to connect the motor and rotate synchronously with it to achieve aging testing under load. By changing the magnitude of the hysteresis device connection current, the load can be adjusted, thereby enabling more comprehensive detection of the motor's aging under different loads and more reliable test results.

[0006] The sliding module includes a guide rail connected to the base plate and a slider slidably mounted on the guide rail. The bottom of the clamping block is fixedly connected to the slider. The clamping block is provided with a limit plug, and the limit plug is provided with a rotating handle. Thus, the slider slides on the guide rail to drive the test module toward or away from it. After the limit plug is inserted into the socket, the rotating handle is tightened to achieve the limit position of the motor.

[0007] The hysteresis device is mounted on the outside of the mounting plate and connected to the coupling via the mounting plate. The positioning block is connected to the end of the coupling, and a plurality of positioning pins are arranged in a circular pattern at equal intervals on the outer end surface of the positioning block. Thus, the coupling is used to achieve synchronous rotation with the motor, and the positioning pins are adapted to the positioning slots on the motor to achieve motor positioning.

[0008] The clamping block and the coupling are located on the same axis. Therefore, the clamping block hole and the clamped motor are located on the same axis, ensuring that the positioning block corresponds to the motor and ensuring the accuracy of the clamping and positioning.

[0009] The clamping block comprises an integral bottom block and a tubular block mounted on the bottom block. The tubular block is provided with an annular groove, a locking block is provided at the bottom of the tubular block, and guide blocks are equidistantly arranged within the annular groove. The outer ends of the guide blocks are provided with guiding slopes. Thus, the locking block is used to achieve locking and the guide block is used to provide guidance during insertion.
