[0002] Motor testing is a means of comprehensive verification of motor design performance and production quality, and provides an important reference for the future use and improvement of motors. As market applications demand higher and higher motor speeds, the demand for high-speed motor testing is also increasing.

[0003] However, traditional motor test benches cannot meet the requirements of high-speed motor testing. The main reason is that the test motor mounting frame, torque sensor, and test motor mounting frame of the bench are divided into three main bodies. The bench with this structure has insufficient rigidity and low alignment accuracy during debugging, which will cause large vibrations during high-speed motor testing. Utility Model Content

[0010] In some embodiments, the motor mounting holes on the first motor support bracket and the second motor support bracket are coaxial.

[0011] In some embodiments, a plurality of threaded holes are provided in an outer circumference of the motor mounting holes on the first motor support bracket and the second motor support bracket.

[0012] On the other hand, the utility model also discloses a high-speed servo motor test platform, including the test tooling as described above, as well as a base platform, a test motor, a torque sensor, a coupling, and a test motor.

[0013] Beneficial effects: The high-speed servo motor test fixture and test platform of the utility model adopts an integrated structural design, which has high strength, and the concentricity of the installation positions of the test motor and the tested motor is good;

[0014] Because the test motor and the accompanying test motor are installed in fixed positions, it is convenient to replace the test motor, and there is no need to perform installation precision debugging, so the test efficiency is high. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0023] The present invention will be further described in detail below through specific implementation examples and in conjunction with the accompanying drawings. Example

[0024] like Figures 1 to 3 As shown, a high-speed servo motor testing tool includes a tool base 1, a base support leg 2, a first motor support frame 3, a coupling mounting base 4, and a second motor support frame 5. The base support leg 2 is evenly distributed and installed at the four corners of the tool base 1, the first motor support frame 3 and the second motor support frame 5 are installed opposite to each other with a certain interval between them, and the coupling mounting base 4 is installed between the first motor support frame 3 and the second motor support frame 5.

[0025] In this embodiment, the tooling base 1, base support legs 2, first motor support frame 3, coupling mounting base 4, and second motor support frame 5 are manufactured using an integrated casting process.

[0026] Furthermore, the fixture base 1, base support legs 2, first motor support frame 3, coupling mounting base 4, and second motor support frame 5 are made of cast steel. The test fixture utilizes a casting process to integrate the test motor mounting frame, the tested motor mounting frame, and the torque sensor mounting position into a single unit, resulting in high structural rigidity. The fixture is fabricated in one go using a five-axis CNC machine tool, ensuring excellent concentricity between the test and tested motor mounting positions.

[0027] In this embodiment, Figure 2 As shown, the base support foot 2 is provided with a bolt mounting hole 6. The setting of the mounting hole 6 facilitates the fixed connection and installation of the test fixture and the test platform to ensure the stability of the test.

[0028] In this embodiment, Figure 3 As shown, the first motor support frame 3 and the second motor support frame 5 are both provided with motor mounting holes 7. During the specific installation test, the shaft of the servo motor is passed through the motor mounting hole and installed with the middle coupling, and the housing of the servo motor is on the other side.

[0029] Further, such as Figure 3 As shown, the motor mounting holes 7 on the first motor support frame 3 and the second motor support frame 5 are coaxial, thereby ensuring the coaxiality between the two motors and ensuring the stability of the test.

[0030] Further, such as Figure 3 As shown, the motor mounting holes 7 on the first motor support frame 3 and the second motor support frame 5 are provided with a plurality of threaded holes in an outer circumferential direction. The motor to be tested and the accompanying test motor can be fixedly mounted on their respective support frames through the threaded holes. Example

[0031] like Figure 4 and Figure 5 As shown, a high-speed servo motor test platform includes a test fixture 8 as in Example 1, as well as a base platform 9, a test motor 10, a torque sensor 11, a coupling 12, and a test motor 13. The test fixture 8 is fixedly mounted on the base platform 9, one end of the test fixture 8 is mounted with the test motor 10, and the other end is mounted with the test motor 13. The coupling 12 is fixedly mounted on the coupling mounting base 4 and is respectively connected to the test motor 10 and the test motor 13. The torque sensor 11 is mounted on the coupling 12.

[0032] Specifically, two parallel slide grooves are provided on the base platform 9, and a plurality of threaded holes with a certain spacing are provided in the slide grooves. The threaded holes are adapted to the bolt mounting holes 6 provided on the base support feet 2, and the test tooling is fixed on the base platform 9 by bolts.

[0033] When the test platform of the present invention is tested specifically: first, the test fixture is fixedly connected and installed through the four bolt mounting holes 6 corresponding to the threaded hole positions in the slide groove; then the test motor 10 and the accompanying test motor 13 are respectively installed on their respective support frames, and the shaft ends are connected to the middle connector 12, and the test is started and the value of the torque sensor 11 is observed.

[0034] When the test is complete and the motor needs to be replaced, you only need to remove the previous test motor and replace it with a test motor, without having to replace the accompanying test motor. This way, the installation position is fixed, the test motor can be easily replaced, and there is no need for installation precision debugging, which improves the test efficiency.

[0035] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
