Detailed Implementation
[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.
[0023] Example: A motor performance testing device, such as Figures 1-4As shown, the system includes a cabinet 1, a mounting platform 2 fixedly mounted on the top of the cabinet 1, a placement rack 3 fixedly mounted at the top center of the mounting platform 2, a drive cylinder 4 with its telescopic end facing forward mounted on the placement rack 3, and a load fan 5 rotatably and slidably mounted on the front side of the placement rack 3. The load fan 5 is used to simulate different load conditions for a comprehensive performance evaluation of the motor under test. The telescopic end of the drive cylinder 4 is keyed to the shaft end of the load fan 5. A laser gun 6 for laser simulation cutting of the load fan 5 is also mounted on both sides of the mounting platform 2. A mounting frame 8 is also fixedly mounted on the mounting platform 2, located in front of the placement rack 3, and a circumferentially openable mounting bracket is mounted on the mounting frame 8. The rotating disk 9 of the arc-shaped groove 91 has four arc-shaped grooves. Clamping rods 10 with the same layout and number as the arc-shaped grooves 91 are slidably passed through the mounting frame 8 along the circumference. The end of the clamping rod 10 is provided with a crossbar 101 that is slidably embedded in the adjacent arc-shaped groove 91. The mounting frame 8 is equipped with a driving component for driving the rotating disk 9 to rotate, so as to cooperate with the arc-shaped groove 91 to push the clamping rods 10 to open and close. The test motor 12 is clamped between the clamping rods 10. The output end of the test motor 12 is keyed to the other end of the load fan blade 5. The mounting platform 2 is equipped with a vibration measuring instrument 7 that is electrically connected to the laser gun 6, and the suction cup end of the vibration measuring instrument 7 is adsorbed on the stator core of the test motor 12.
[0024] As can be seen from the above, in order to ensure the adaptive clamping and fixing of the test motor 12, the rotating disk 9 is driven to rotate by the driving component. Under the action of the arc groove 91, the clamping rods 10 are driven to expand or close under the action of the corresponding crossbars 101, so as to present different opening and closing states. This ensures that test motors 12 of different specifications can be stably placed between the clamping rods 10 to achieve adaptive clamping and fixing. Furthermore, under the action of the vibration measuring instrument 7, it is attracted to the stator iron core of the test motor 12, so as to monitor the vibration of the test motor 12 in real time. Then, according to the magnitude of the vibration value of the test motor 12, the corresponding laser is emitted by the laser gun 6, so as to simulate the cutting of the load fan blade 5 by laser, so as to realize the performance testing of the test motor 12.
[0025] like Figure 4 As shown, the driving component includes a gear ring 92 and an electric gear 11. The electric gear 11 is mounted on the mounting bracket 8, and the gear ring 92 is provided on the rotating disk 9 to mesh with the electric gear 11. Through the meshing of the electric gear 11 and the gear ring 92, the rotating disk 9 is driven to rotate, thereby controlling the opening and closing of the clamping rod 10 to achieve effective clamping and release of the test motor 12.
[0026] like Figure 1 and Figure 5As shown, it also includes a mounting shaft 13 and a protective housing 14. A mounting shaft 13 is provided on each of the left and right sides of the placement frame 3, and a protective housing 14 rotates between the two mounting shafts 13 to cover the load fan blade 5 during testing, thereby protecting the operator from injury caused by the high-speed rotating load fan blade 5.
[0027] like Figure 5 As shown, it also includes magnets 15. A set of magnets 15 is provided on each of the two rear sides of the protective shell 14. The two magnets 15 in the same set are arranged at right angles, and the magnets 15 are magnetically attracted to the mounting platform 2 to help fix the position of the protective shell 14 and ensure its stability in the open or closed state.
[0028] like Figure 5 As shown, it also includes a pull frame 16. The front of the protective shell 14 is provided with a pull frame 16, which allows the operator to easily move the protective shell 14.
[0029] like Figure 2 As shown, it also includes a shelf 17. The cabinet 1 is equipped with a shelf 17, which provides additional storage space for items and helps to keep the work area tidy.
[0030] During use, ensure the device is placed stably. Then, grasp the pull frame 16 and push the protective housing 14 to rotate along the mounting shaft 13 until it opens at a 90-degree angle. At this point, the magnet 15 will magnetically attract and fix to the mounting platform 2, thus stabilizing the protective housing 14 in the open state. Next, activate the electric gear 11 to engage with the gear ring 92, driving the rotating disk 9 to rotate. Under the action of the arc groove 91, the crossbar 101 slides accordingly, pulling the connected clamping rod 10 to move synchronously, realizing the expansion or closure of the clamping rod 10. First, control the clamping rod 10 to expand so that the motor 12 to be tested can be placed into the rotating disk 9; then, activate the electric gear 11 again to drive the gear ring 92 and the rotating disk 9 to rotate, causing the clamping rod 10 to gradually close until its end is tightly against the surface of the test motor 12, achieving a stable clamping. After clamping is complete, activate the drive cylinder 4 to push the load fan blade 5, so that its shaft end aligns with the output end of the test motor 12. The protective casing 14 is then closed, and the magnet 15 on the other side automatically adheres and fixes itself, ensuring overall sealing and stability. Finally, the test motor 12 is started, and the vibration measuring instrument 7 and laser gun 6 are simultaneously activated. The vibration measuring instrument 7 is attached to the stator core of the test motor 12 via a suction cup to collect vibration data during operation; the laser gun 6 is aimed at the simulated load fan blade 5, and based on the collected vibration values, the laser gun 6 is further controlled to laser-cut the simulated load fan blade 5, thereby obtaining the operating power and vibration performance of the test motor 12 under different loads, achieving an accurate evaluation of the comprehensive performance of the test motor 12.
[0031] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
