The protective cover 2 is clamped on the upper part of the test bench 1, and the sealing door 3 is rotatably connected to the front side of the upper left part of the protective cover 2. A handle is provided on the left side of the part, which is convenient for grasping and opening the sealing door 3. A feed pipe 4 is connected to the upper part of the protective cover 2. A motor 5 is connected to the inner side of the middle part of the test bench 1. A rotating shaft 6 is connected to the output shaft of the motor 5. The rotating shaft 6 is rotatably connected to the test bench 1. A first sliding frame 7 is slidably connected to the rotating shaft 6. A first telescopic spring 8 is connected between the upper side of the rotating shaft 6 and the first sliding frame 7. A second telescopic spring 9 is connected between the lower side of the first sliding frame 7 and the rotating shaft 6. The upper part of the first sliding frame 7 is connected to The diameter of the rotating shaft 6 is larger than that of the mounting rod 10. Three slide rails 11 are connected to the upper part of the first sliding frame 7. The slide rails 11 are evenly distributed along the first sliding frame 7. A common screw rod 12 is rotatably connected to the slide rail 11 at the right front. A handle is provided at the lower part of the common screw rod 12 for easy hand-gripping and rotation of the common screw rod 12. An extrusion frame 13 is connected to the common screw rod 12 by threading. The slide rails 11 are all slidably connected to the extrusion frame 13. The inner side of the upper part of the test bench 1 is connected to the left and right top pressure frames 14. A support block 15 is connected to the upper side of the protective cover 2, and a bidirectional screw rod 16 is rotatably connected to the support block 15. The left and right parts of the bidirectional screw rod 16 are connected to the second sliding frame 17 by threads. The second sliding frames 17 are all slidably connected to the protective cover 2. The second sliding frames 17 are all L-shaped. The lower side of the second sliding frames 17 that are close to each other are slidably connected to the clamping frames 18. The clamping frames 18 are all T-shaped. A third telescopic spring 19 is connected between the clamping frames 18 and the second sliding frames 17 on the same side.

[0032] When the contact pressure test of the conductive slip ring is required, the device can be used. According to the size of the conductive slip ring, the mounting rod 10 of suitable specifications is brought into contact with the first sliding frame 7, and then the mounting rod 10 is rotated to install it. Then the protective cover 2 is clamped with the test bench 1, and then the sealing door 3 is opened by turning the handle, and then the conductive slip ring with the shell is installed on the mounting rod 10, so that the mounting rods 10 of different specifications can be replaced to install the conductive slip rings of different sizes, which is convenient for testing the conductive slip rings of different sizes and improves the flexibility of use. Then, by rotating the bidirectional lead screw 16, the second sliding frame 17 is moved along the protective cover 2 at the same time under the action of the thread, and the second sliding frame 17 are all L-shaped, so that the clamping frame 18 moves at the same time to contact the outer shell of the conductive slip ring for clamping. The clamping frame 18 is all T-shaped, and then the sealing door 3 is rotated in the opposite direction to close, and then water of different temperatures is added to the feed pipe 4 in turn, and then the feed pipe 4 is blocked with a plug, and then the ordinary screw rod 12 is rotated by the handle, and the extrusion frame 13 moves along the slide rail 11 under the action of the thread, and the slide rail 11 is evenly distributed along the first slide frame 7, and then the vibration amplitude is adjusted. After moving to a suitable position, the motor 5 is started, and the motor 5 drives the rotating shaft 6 to rotate. The diameter of the rotating shaft 6 is larger than the diameter of the mounting rod 10, so that the first slide frame 7, the mounting rod 10, the slide rail 11 and the extrusion frame 1 3 rotates, so that the conductive slip ring rotates for testing, and at the same time, the extrusion frame 13 contacts the top pressure frame 14, so that the first sliding frame 7 moves upward, and then drives the installation rod 10 to move upward, and the first telescopic spring 8 and the second telescopic spring 9 are deformed, so that the conductive slip ring moves upward. When the extrusion frame 13 is separated from the top pressure frame 14, the first telescopic spring 8 and the second telescopic spring 9 rebound, and the first sliding frame 7 moves downward to reset, so that the installation rod 10 and the conductive slip ring move downward to reset, and then the conductive slip ring vibrates up and down, and then the contact pressure test of the conductive slip ring is realized, so that the contact pressure of the conductive slip ring can be tested for sealing under different temperature conditions and different vibration amplitudes. It is convenient to comprehensively evaluate the stability and performance of the conductive slip ring, prevent interference, improve the reliability of the test, and is flexible and convenient to use. During the test, the outer shell of the conductive slip ring is buffered under the action of the third telescopic spring 19, so that the outer shell of the conductive slip ring can be clamped and buffered at the same time to prevent damage to the outer shell and displacement of the conductive slip ring, thereby improving the stability of the test. After the test is completed, the motor 5 is turned off, and the sealing door 3 is rotated to open it, and then the bidirectional screw rod 16 is rotated in the reverse direction. Under the action of the thread, the second sliding frame 17 is simultaneously moved in the reverse direction, so that the clamping frame 18 is moved in the reverse direction to be separated from the outer shell of the conductive slip ring, and then the conductive slip ring is removed, and then the sealing door 3 is rotated to close it.
