Description

Technical Field

[0001] This application belongs to the field of motor performance testing and testing technology, specifically a tooling for testing motor torque, speed and temperature. Background Technology

[0002] With the rapid development of industrial automation, new energy vehicles, and intelligent manufacturing, the accurate testing of motor performance indicators has become crucial as a core power device. Among these, motor torque, speed, and temperature are key parameters for evaluating operational performance. To ensure the reliability, efficiency, and safety of motors under various operating conditions, these parameters require comprehensive testing with high precision and stability during R&D, production, and quality control. Traditional motor testing often uses separate instruments to measure torque, speed, and temperature, resulting in low testing efficiency, poor data synchronization, and complex operation. This is particularly problematic in mass production or long-term aging tests, where it fails to meet the demands for automation and integration. Therefore, developing a motor testing fixture that integrates torque, speed, and temperature detection has become a key technological direction for improving the efficiency and accuracy of motor testing.

[0003] However, common motor torque, speed and temperature testing fixtures are not convenient for quick installation of the motor under test, and repeated installation can easily introduce tolerances, resulting in errors in the test data. Utility Model Content

The tail end of the motor is fixed through the suspension fixing hole at the back end of the motor. Then, by fixing the torque, speed and temperature testing shaft to the motor shaft, the operation of this equipment can enable the new energy vehicle motor to be tested to be installed quickly and ensure that repeated installations are tolerable.

[0007] In a preferred embodiment, the inner sides of the device connecting plate, the fixing sleeve, and the motor fixing plate are provided with through holes, and a torque, speed, and temperature testing shaft is installed at the central axis of the through hole.

[0014] By adopting the above technical solution and using the support plate, the stability of the connection between the left connecting plate, the right connecting plate, and the equipment connecting plate can be guaranteed.

[0015] In a preferred embodiment, a left connecting plate sliding protrusion and a right connecting plate sliding protrusion are fixedly connected to the outer sides of the left connecting plate and the right connecting plate, respectively. A left connecting plate sliding protrusion groove and a right connecting plate sliding protrusion groove are respectively opened on both sides of the suspension fixing plate. The left connecting plate sliding protrusion and the right connecting plate sliding protrusion are slidably connected to the outer sides of the left connecting plate sliding protrusion and the right connecting plate sliding protrusion groove, respectively.

[0016] By adopting the above technical solution, the sliding protrusions of the left and right connecting plates can be slid into the sliding protrusions of the left and right connecting plates respectively by pulling the sliding protrusion groove of the right connecting plate, which facilitates the placement and removal of the motor to be tested.

The end face of the rotating shaft of the motor to be tested is fixed to the back side of the motor fixing plate 3 through the motor front fixing hole 4. The suspension fixing plate 10 is pushed forward. At this time, the sliding protrusion 11 of the right connecting plate and the sliding protrusion 13 of the left connecting plate will slide in the sliding protrusion groove 12 of the right connecting plate and the sliding protrusion groove 14 of the left connecting plate, respectively, so that the suspension fixing plate 10 abuts against the tail end of the motor to be tested.
