[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model discloses a motor testing device, including a test platform 1 and a positioning plate 4. The test platform 1 has a slot 2 in the middle part. Two positioning platforms 3 are symmetrically arranged on both sides of the positioning plate 4. The lower end of the positioning platform 3 is provided with a slider 5 that is slidably connected to the slot 2. The lower end of the positioning platform 3 is provided with a base frame 6. The lower end of the base frame 6 is provided with a toothed plate 7. The test platform 1 is provided with a support plate below it. The upper end of the support plate is provided with a motor 8. The output end of the motor 8 is provided with a rotating shaft 9. The rotating shaft 9 is provided with a gear 10 that meshes with the toothed plate 7.

[0024] The positioning platform 3 is provided with a base plate 11 below it. The four corners of the base plate 11 are provided with limiting rods 12 that penetrate the positioning platform 3. The middle part of the lower end of the positioning platform 3 is provided with a cavity 14. A spring is provided in the cavity 14. The middle part of the base plate 11 is provided with a vertical rod 15 that is inserted into the cavity 14 and connected to the spring.

[0025] Two limiting components are provided in the symmetrical empty slot 2 at the upper end of the test bench 1.

[0026] In this embodiment, a pull rod 13 is provided at the lower end of the base plate 11, which makes the base plate 11 easy to operate.

[0027] When the testing device for motor 8 is in operation, all components work closely together to complete the testing of motor 8 in an orderly manner. The operator first pulls the lever 13 below the base plate 11. This action causes the base plate 11 to move downwards, and the vertical rod 15 in the middle of the base plate 11 stretches the spring in the lower cavity 14 of the positioning platform 3. Then, the motor 8 to be tested is placed on the positioning platform 3, and its position is carefully adjusted so that the through hole on the base of motor 8 is precisely aligned with the limiting rods 12 at the four corners of the base plate 11 that pass through the positioning platform 3. After releasing the lever 13, the spring returns to its original shape using its elastic potential energy, pushing the base plate 11 upwards. The limiting rods 12 then pass through the through hole on the base of motor 8, thus achieving the initial stable placement of motor 8 on the positioning platform 3.

[0028] In this embodiment, the limiting component includes a fixed frame 16 and a telescopic component 17. The fixed frame 16 is fixed to the upper end of the test platform 1, and the telescopic component 17 is fixed to the upper end of the fixed frame 16. The output end of the telescopic component 17 is provided with a clamping plate 18, and the two ends of the clamping plate 18 are provided with clamping blocks 19. The plurality of clamping blocks 19 are all cylindrical structures. The output end of the telescopic component 17 is provided with a push rod connected to the clamping plate 18.

[0029] Next, the limiting components symmetrically positioned above the test bench 1 and opposite the empty slot 2 begin to operate. The cylinder (i.e., the telescopic component 17) in the limiting components is activated, and the cylinder pushes the clamping plate 18 through the push rod, causing the cylindrical clamping blocks 19 at both ends of the clamping plate 18 to move towards the motor 8, thus firmly clamping the motor 8 from multiple angles and ensuring that the motor 8 will not shake or shift during the test, providing a reliable guarantee for accurate testing.

[0030] In this embodiment, the motor 8 is a servo motor, and the telescopic component 17 is a cylinder.

[0031] After motor 8 completes the test, the clamping block 19 first releases its grip on motor 8, and then the servo motor on the support plate below the test bench 1 is started. The output end of the servo motor drives the rotating shaft 9 to rotate. The gear 10 on the rotating shaft 9 meshes with the gear plate 7 below the base frame 6, thereby driving the base frame 6 and the two positioning platforms 3 connected to it to slide smoothly along the empty groove 2 in the middle of the test bench 1. One positioning platform 3 moves the tested motor 8 out of the test area, while the other positioning platform 3 precisely moves the next motor 8 to be tested to the center of the test bench 1 to carry out a new round of testing. At this time, the operator can easily remove the tested motor 8. The whole process is completed in one go, realizing a seamless connection between the motor 8 testing and unloading process.

[0032] Compared to traditional motor testing devices, this device offers significant advantages. In terms of ease of operation, the ingenious combination of the pull rod 13, spring, and limiting rod 12 greatly simplifies the motor clamping process. Operators can quickly complete the motor 8 positioning without complex procedures. Simultaneously, the design of the limiting components, especially the cylindrical clamping block 19, clamps the motor 8 from multiple directions, further enhancing the stability of the motor 8's fixation, effectively avoiding testing errors caused by insecure motor 8 fixation, and significantly improving the accuracy of the test results.

[0033] In terms of testing efficiency, this device adopts a movable positioning stage 3 design. After one motor 8 has finished testing, the positioning stage 3 is moved by a servo motor, which can immediately send the next motor 8 to be tested into the testing area. There is no need to wait for unloading to complete before starting a new round of testing, truly realizing continuous operation of motor 8 testing. This design significantly shortens the overall testing time, significantly improves the testing efficiency of motor 8, and fully meets the needs of industrial production and scientific research experiments for efficient testing of motor 8.
