Abstract
Description
Technical Field
[0001] This utility model relates to the field of motor testing technology, specifically a high-power motor rotor deflection testing device. Background Technology
[0002] The rotor of an electric motor or generator is a crucial component. It typically consists of a rotating shaft and conductors fixed to the shaft. When an electric current passes through these conductors, they experience a force in the magnetic field, driving the shaft to rotate. This rotational motion can be converted into mechanical energy to power various devices. Simultaneously, if an external force causes the rotor to rotate, an electric current can be generated in the conductors through electromagnetic induction, thus achieving energy conversion.
[0003] However, in existing technologies, traditional devices require high-speed rotation of the motor rotor for deflection testing. This necessitates external fixation of the motor to ensure stability during the test. However, different motor models may not be stably fixed during rotor deflection testing, leading to potential shaking or movement due to high-speed rotation, thus affecting the test results. Therefore, we provide a high-power motor rotor deflection testing device. Utility Model Content

[0007] As a further preferred embodiment of this technical solution, two adjustment grooves are provided on the top of the base plate near the test plate. The outer side of the adjustment block is slidably connected to the inner wall of the adjustment groove. A coupling is movably installed on the side of the test plate away from the cylinder.

[0012] This utility model provides a high-power motor rotor deflection detection device, which has the following beneficial effects:

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0022] This utility model provides a technical solution: such as Figures 1-4As shown in this embodiment, a high-power motor rotor deflection detection device includes: a fixing mechanism 1, which includes a base plate 11. A mounting seat 12 is provided on one side of the top of the base plate 11. Fixing blocks 13 are provided on both sides of the top of the mounting seat 12. A lead screw 14 is provided in the threaded groove of each of the two fixing blocks 13. The mounting seat 12 is fixedly connected to one side of the top of the base plate 11. Fixing blocks 13 are fixedly connected to both sides of the top of the mounting seat 12. The inner wall of the threaded groove of the fixing block 13 is threadedly connected to the outer wall of the lead screw 14. A bearing seat 15 is provided at one opposite end of each of the two lead screws 14. A clamping block 16 is provided on one opposite side of each of the two bearing seats 15. A slider 19 is provided on both sides of the bottom of each of the two clamping blocks 16. One end of the lead screw 14 is fixedly connected to the inner wall of the bearing seat 15. The outer wall of the bearing seat 15 is fixedly connected to the side of the clamping block 16 near the lead screw 14. Both sides of the bottom of block 16 are fixedly connected to sliders 19. Both sides of the top of mounting base 12 are provided with two sliding grooves 17. The top of mounting base 12 is provided with a placement groove 18. The motor housing 110 is provided in the placement groove 18. The outside of slider 19 is slidably connected to the inner wall of sliding groove 17. The outside of motor housing 110 is connected to the placement groove 18. The inside of motor housing 110 is provided with rotor body 111. One end of rotor body 111 is provided with rotating rod 112. Four positioning blocks 113 are arranged in a ring array on the outside of the end of rotating rod 112 away from rotor body 111. The four positioning blocks 113 are fixedly connected in a ring array on the outside of the end of rotating rod 112 away from rotor body 111. The positioning blocks 113 are connected to the positioning groove 25. The end of rotating rod 112 away from rotor body 111 is connected to the coupling 24. The top of base plate 11 is provided with a test mechanism 2 on the side away from mounting column.
[0023] In this embodiment, when the operator needs to perform deflection testing on the motor rotor, the motor can be placed in the placement slot 18 opened on the top of the mounting base 12. The distance between the two clamping blocks 16 is adjusted according to the size of the motor to ensure that the two clamping blocks 16 can firmly fix the motor housing 110. Therefore, the operator can rotate the lead screws 14 on both sides of the top of the mounting base 12. When the lead screws 14 are rotated, they will drive the clamping blocks 16 to move horizontally. During the movement of the clamping blocks 16, the slider 19 will slide in the slide groove 17, thereby ensuring the stability of the clamping blocks 16 during movement. When the two clamping blocks 16 move to the designated position, they will clamp and fix the top two sides of the motor housing 110, thereby ensuring that different models of motors can be stably tested for rotor deflection on the device, avoiding the phenomenon that the motor may shake or move due to high-speed rotation of the rotor.
[0024] like Figures 1-4As shown, the testing mechanism 2 includes a test plate 21. Adjusting blocks 23 are fixedly connected to both ends of the bottom of the test plate 21. A cylinder 22 is fixedly installed on the top side of the base plate 11 away from the mounting column. The output end of the cylinder 22 is fixedly connected to the side of the test plate 21 away from the mounting base 12. Two adjusting grooves 26 are opened on the top side of the base plate 11 near the test plate 21. The outside of the adjusting block 23 is slidably connected to the inner wall of the adjusting groove 26. A coupling 24 is movably installed on the side of the test plate 21 away from the cylinder 22. A positioning groove 25 is opened on the inner wall of the coupling 24.
[0025] In this embodiment, before the testing process, the operator can start the cylinder 22, which can then drive the test plate 21 to move forward or backward on the base plate 11. Therefore, when the test plate 21 moves forward, the rotating rod 112 will be connected to the inside of the coupling 24 through the positioning block 113 and the positioning groove 25. After the motor is started, the rotor, the rotating shaft and the coupling 24 will rotate at high speed, and the test plate 21 will detect the deflection of the rotor during rotation.
[0026] This utility model provides a high-power motor rotor deflection detection device, the specific working principle of which is as follows:
[0027] When the operator needs to perform deflection testing on the motor rotor, the motor is placed in the placement slot 18 on the top of the mounting base 12. This ensures that the motor maintains a stable position during the testing process. The distance between the two clamping blocks 16 is adjusted according to the size of the motor. By adjusting the distance between the clamping blocks 16, it is ensured that the two clamping blocks 16 can firmly fix the motor housing 110, preventing shaking or displacement during the testing process. When the lead screw 14 is rotated, it will drive the clamping blocks 16 to move horizontally. By controlling the rotation direction and angle of the lead screw 14, the clamping blocks 16 can be moved to the designated position, thereby fixing the motor housing 110. The top two sides of the outer casing are clamped and fixed to ensure that different models of motors can be stably tested for rotor deflection on the device. Before the test, the operator can start the cylinder 22 to make the test plate 21 move forward or backward on the base plate 11. This allows the position of the test plate 21 to be adjusted as needed. When the test plate 21 moves forward, the rotating rod 112 will be connected to the coupling 24 through the positioning block 113 and the positioning groove 25. After the motor is started, the rotor, the rotating shaft and the coupling 24 will rotate at high speed, which can simulate the rotor operation under actual working conditions, so as to more accurately detect the rotor deflection.
[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
