[0034] When the outer wall of the transmission shaft body 6 needs to be cleaned, the hydraulic cylinder 8 can be started, and the lower cleaning plate can be pushed upward by the hydraulic cylinder 8. When the lower cleaning plate moves upward, the L-shaped rod 18 and the first rack 19 on one side will be driven to move upward together. When the first rack 19 moves upward, the gear 12 will be driven to rotate. When the gear 12 rotates, it will drive the rotating rod 11 and the connecting plate 13 on one side to rotate together. When the connecting plate 13 rotates, it will drive the upper cleaning plate 14 to rotate until the upper cleaning plate 14 flips over to the top of the lower cleaning plate 9, so that the plug 16 provided at the bottom of the upper cleaning plate 14 can be inserted into the socket 17 at the top of the lower cleaning plate 9.

After the installation of the drive shaft body 6 is completed, the vertical pole 55 and the supporting piece 56 can be removed from the top of the closing plate 46 to facilitate dynamic detection of the drive shaft body 6.

[0045] Working principle: In order to solve the problem that impurities attached to the surface of the transmission shaft affect the test results, when the transmission shaft body 6 needs to be tested, the two ends of the transmission shaft body 6 can be installed on the first fixed head 4 and the second fixed head 5 respectively, and then the hydraulic cylinder 8 is started to push the lower cleaning plate to move upward. When the lower cleaning plate moves upward, it will drive the L-shaped rod 18 and the first rack 19 on one side to move upward together. When the first rack 19 moves upward, it will drive the gear 12 to rotate, and when the gear 12 rotates, it will drive the rotating rod 11 and the connecting plate 13 on one side to rotate together. When the connecting plate 13 rotates, the upper cleaning plate 14 is driven to rotate until the upper cleaning plate 14 flips over to the top of the lower cleaning plate 9, and the plug 16 provided at the bottom of the upper cleaning plate 14 is inserted into the socket 17 at the top of the lower cleaning plate 9, so that the inner walls of the upper cleaning plate 14 and the lower cleaning plate 9 are connected to each other. At this time, the transmission shaft body 6 is provided between the upper cleaning plate 14 and the lower cleaning plate 9, and the pump 23 can be started to pump the water in the water tank 21 into the transmission pipe 22 through the pump 23, and transmit it to the inner wall of the upper cleaning plate 14 through the transmission pipe 22 and the hose, and The water flows into the inner wall of the lower cleaning plate 9 through the plug 16, and then the thrust generated by the pump 23 causes the water to be sprayed out through the multiple nozzles 15, which can rinse the surface of the transmission shaft body 6 at the center and clean the impurities attached to the outer wall of the transmission shaft body 6, thereby preventing the attached impurities from affecting the results of the transmission shaft detection. By starting the built-in motor, the reciprocating screw 50 can be driven to rotate. When the reciprocating screw 50 rotates, it will drive the screw nut pair 51 set on the outer wall to move back and forth. Since the screw nut pair 51 is fixedly connected to the base plate 7, the screw nut When the pair 51 moves back and forth, it will drive the bottom plate 7 and the cleaning assembly to move back and forth together. When cleaning the transmission shaft body 6, the cleaning assembly can be moved back and forth to clean a larger area on the surface of the transmission shaft body 6, thereby facilitating the cleaning of the surface of the transmission shaft body 6. By providing two sets of baffles 53 on both sides of the lead screw nut pair 51, a water barrier effect can be achieved during movement. By providing a cleaning cylinder 52 at the bottom of the baffle 53, the surface of the reciprocating lead screw 50 can be pre-cleaned by the cleaning cylinder 52 when the lead screw nut pair 51 moves. When the first rack 19 drives the gear 12 to rotate, the second rack 42 on the other side will be driven to move downward through the gear 12. The short groove on one side of the bottom plate 7 can be used to limit the movement trajectory of the second rack 42. The downward movement of the second rack 42 will push the round rod 43 and the slider 44 to move downward. The round rod 43 and the slider 44 will rotate when moving downward to keep the slider 44 inside the slide frame 45. When the second rack 42 moves downward, one side of the closing plate 46 will be flipped downward, so that when the waste water generated by cleaning the transmission shaft body 6 flows downward, the waste water can be guided downward into the collection tank through the closing plate 46 tilted to one side. By setting the second guide groove 48, the waste water can flow into the collection box 49 on one side and be cleaned on the upper plate 1 When the handle 4 is turned over, the two sets of fixing pieces 24, connecting pieces 25, mounting pieces 26 and cleaning pads 27 on both sides thereof will turn over together. When the upper cleaning pad 27 is turned over to the top of the lower set of cleaning pads 27, the two sets of inserting blocks 28 can be inserted into the inner walls of the two sets of slots 29, so that the upper and lower sets of cleaning pads 27 are tightly closed to prevent water from being unable to be wiped away in the gaps during wiping. When cleaning the surface of the transmission shaft body 6, the four sets of cleaning pads 27 can be used to wipe the surface of the transmission shaft to clean stubborn impurities on the surface of the transmission shaft body 6. At the same time, the cleaning pads 27 and the inserting blocks 28 are made of cleaning sponges, so the water on the surface of the transmission shaft body 6 can be wiped dry to prevent water from remaining on the surface of the transmission shaft body 6. When it is necessary to measure the performance of the transmission shaft body 6 under different humidity environments, the first cover plate 30 and the second cover plate 31 can be moved toward the center at the same time until the first cover plate 30 fits with the second cover plate 31, so that the first sealing gasket 33 can be inserted into the groove of the second sealing gasket 34, so that the connection between the first cover plate 30 and the second cover plate 31 is sealed. By arranging the third sealing gasket 41 on one side of the first cover plate 30 and the second cover plate 31, it is convenient to seal the gap between the fan 36 between the first cover plate 30 and the detection machine 2 and the gap between the second cover plate 31 and the fixed seat 3. The humidity of the air between the first cover plate 30 and the second cover plate 31 can be detected by the monitoring probe 57. When it is necessary to increase the humidity around the transmission shaft body 6, the first sealing gasket 33 can be inserted into the groove of the second sealing gasket 34, so that the connection between the first cover plate 30 and the second cover plate 31 is sealed. The humidifier 32 is used to increase the humidity around the drive shaft body 6. The various performances of the drive shaft body 6 in a high humidity environment can be detected. When the humidity needs to be reduced, the mounting plate 38 can be pulled to one side. When the mounting plate 38 moves to one side, the first sealing plate 39 and the second sealing plate 40 can be pulled to one side, so that the humid air in the first cover plate 30 and the second cover plate 31 can contact the dehumidifier in the placement frame 37, thereby reducing the humidity of the air. When the air humidity is high, the fan 36 can be started, and the humid air in the first cover plate 30 and the second cover plate 31 can be extracted by the fan 36. The extracted humid air can be dried and the extraction of the humid air can be accelerated so that the humidity around the drive shaft body 6 reaches a suitable range.
