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.

[0018] Example: Figure 1-4 As shown, this utility model provides a motor test structure that facilitates the replacement of test pieces, including a test bench 1, a test motor 10 and a square block 20. The upper surface of the test bench 1 is respectively provided with a test replacement component 2 and a pushing component 3. By setting the test replacement component 2 and the pushing component 3, the test replacement component 2 can realize the replacement of different loads, and the pushing component 3 can make the test motor 10 move horizontally to realize the speed test of the test motor 10 under different loads. The test replacement component 2 includes a rotating disk 21, which is rotatably mounted at one end of the upper surface of the test bench 1. Four fixed disks 22 arranged in a ring array are fixedly mounted on the upper surface of the rotating disk 21. A test shaft 23 is rotatably mounted on one side of each fixed disk 22. When the drive shaft of the test motor 10 is connected to the end of the test shaft 23, the drive shaft of the test motor 10 can cause the test shaft 23 to rotate. Several counterweight rings 24 are movably fitted onto the test shaft 23. By adding or removing the counterweight rings 24, the weight of the test shaft 23 can be increased. The weight of the test shaft 23 can be adjusted by increasing or decreasing the number of counterweight rings 24. During the rotation of the test motor 10, the speed of the test motor 10 is tested under different loads. A limit plate 25 is detachably installed at one end of the test shaft 23. By setting the limit plate 25, the limit plate 25 can limit and fix the counterweight ring 24 on the test shaft 23. A threaded groove 251 is provided on the outer wall of the test shaft 23. The inner wall of the limit plate 25 and the threaded groove 251 are threadedly rotatably connected. By setting the threaded groove 251, the limit plate 25 can be fixed on the test shaft 23. At the same time, the limit plate 25 can be disassembled to facilitate the addition or removal of the counterweight ring 24. A weight display is detachably installed on the other side of the fixed plate 22. 26. By setting up a weight display 26, the weight of the test shaft 23 can be read through the weight display 26 when the counterweight ring 24 is added or removed. Several mounting bolts 261 are provided on one side of the weight display 26. One end of the mounting bolts 261 is threadedly connected to the threaded hole on the other side of the fixed plate 22. The weight display 26 can be mounted on the fixed plate 22 by means of the mounting bolts 261, and the weight display 26 can also be disassembled. One end of the test shaft 23 is provided with a square groove 27. By setting the square groove 27, when the square block 20 is assembled onto the drive shaft of the test motor 10, the test motor 10 is pushed toward the square groove 27. 7. The square block 20 is horizontally inserted into the square slot 27. When the drive shaft of the test motor 10 rotates, the drive shaft of the test motor 10 can make the test shaft 23 rotate through the square block 20 and the square slot 27. A drive motor 28 is fixedly installed at one end of the lower surface of the test platform 1. A rotating rod 29 is fixedly installed at the drive output end of the drive motor 28. One end of the rotating rod 29 is fixedly connected to the axis of the rotating disk 21. By starting the drive motor 28, the drive shaft of the drive motor 28 can make the rotating disk 21 rotate through the rotating rod 29, so that the four test shafts 23 can revolve in a circle, so that the four test shafts 23 correspond one by one with the test motor 10. The driving component 3 includes a mounting platform 31, on which several grooves 32 are provided. By providing the grooves 32, the test motor 10 can be assembled onto the mounting platform 31 by bolts and the grooves 32. A fixing frame 33 is fixedly provided at the other end of the test platform 1. A cylinder 34 is fixedly provided at one end of the fixing frame 33. The piston end of the cylinder 34 is fixedly connected to one side of the mounting platform 31. By activating the cylinder 34, the piston end of the cylinder 34 can push the mounting platform 31 to move horizontally, thereby enabling the test motor 10 to move horizontally, so that the square block 20 enters into the square groove 27, or detaches the square block 20 from the square groove 27. Several guide grooves 35 are provided at the other end of the upper surface of the test platform 1. Several guide blocks 36 are fixedly provided on the lower surface of the mounting platform 31. The guide blocks 36 are slidably provided on the inner wall of the guide grooves 35. By providing the guide grooves 35 and the guide blocks 36, the guide blocks 36 can slide horizontally along the inner wall of the guide grooves 35, thereby improving the stability of the mounting platform 31.

[0019] Working principle: When the speed of the test motor 10 needs to be tested, the tester first assembles different numbers of counterweight rings 24 on the four test shafts 23 according to the test requirements. Specifically, the four limit plates 25 are manually rotated to disengage the four limit plates 25 from the four test shafts 23. Then, different numbers of counterweight rings 24 are put on the four test shafts 23 respectively. At the same time, the weight of the four test shafts 23 is read through the four weight displays 26. Then, the four limit plates 25 are assembled on the four test shafts 23. Subsequently, the test motor 10 is mounted on the mounting platform 31, and the cylinder 34 is activated. The piston end of the cylinder 34 extends, pushing the mounting platform 31 to move horizontally towards one side of the rotating disk 21. At this time, the test motor 10 and the square block 20 move horizontally in sync, so that the square block 20 is horizontally inserted into one of the square slots 27 (if the square slot 27 and the square block 20 are misaligned, the test shaft 23 is manually rotated to match the square slot 27 with the square block 20). Then, the test motor 10 is activated, and the drive shaft of the test motor 10 rotates one of the test shafts 23 through the square block 20 and the square slot 27. Then, the test head of the motor tachometer is held and pointed at the drive shaft of the test motor 10, and the motor tachometer is used to read the speed data of the test motor 10 under different loads. After the test of a single test axis 23 is completed, the tester turns off the test motor 10 and turns on the cylinder 34 to disengage the square block 20 from the square slot 27. Then, the drive motor 28 is started. The drive motor 28 rotates the rotating disk 21 through the rotating rod 29. At this time, the four test axes 23 on the rotating disk 21 revolve around the circumference. After rotating 90 degrees, another test axis 23 is horizontally aligned with the test motor 10. Then, the next load test is completed according to the above steps.
