[0002] The drive shaft is the shaft in the universal transmission device that can transmit power. It is a high-speed, less-supported rotating body, so its dynamic balance is very important.

For front-engine, rear-wheel drive vehicles, it is the shaft that transmits the rotation of the transmission to the main reducer. It can have several sections, and the sections can be connected by universal joints. A torsional strength test device is required for testing the drive shaft.

In the present invention, the mechanical transmission shaft detection device is provided with a control button on the top inner wall of the lateral groove, so that when the mounting plate moves up to contact the control button, the clamping force of the clamp is still insufficient to prevent the transmission shaft from slipping. The control button is pressed to control the hydraulic cylinder to stop feeding, and the detection device can be reset, the initial output pressure of the cylinder can be adjusted, and the transmission shaft can be clamped again to meet the needs and avoid the transmission shaft slipping due to loose clamping, which affects the detection results; 6. In the present invention, the mechanical transmission shaft detection device can gradually increase the clamping force to meet the needs when the transmission shaft slips during the detection process through a trigger mechanism, and can independently adjust the surface roughness and size of the two ends of the adaptive transmission shaft to avoid inaccurate detection results caused by too small clamping force, and avoid waste of resources and pressure loss on the transmission shaft caused by excessive initial clamping force, and can automatically stop the experiment and observe the results when the connecting shaft does not slip.

[0026] In this embodiment, the top of the upper clamping plate 5 and the bottom of the lower clamping plate 6 are fixedly connected with guide plates 401, and the rotating drum 4 is slidably sleeved on the outer side of the corresponding guide plates 401, thereby guiding the upper clamping plate 5 and the lower clamping plate 6.

[0027] In this embodiment, hydraulic cylinders 8 are fixedly connected to both sides of the top of the base 1, and a pressure sensor 9 is fixedly connected to the output end of the hydraulic cylinder 8. The top of the pressure sensor 9 is fixedly connected to the bottom of the driving plate 12, and the driving plate 12 is slidably sleeved on the outer sides of the two support plates 2. A control button 30 is fixedly connected to the top inner wall of the lateral groove, and the control button 30, the hydraulic cylinder 8 and the controller 10 are electrically connected.

[0028] In this embodiment, one of the arc-shaped connecting plates 14 is hinged to the front side of the corresponding rotating drum 4, and the other arc-shaped connecting plate 14 is hinged to the rear side of the corresponding rotating drum 4. When the driving plate 12 moves upward, it controls the two rotating drums 4 to rotate in opposite directions.

[0029] In this embodiment, two limiting rings are fixedly sleeved on the outer side of the rotating drum 4 , and the limiting rings are movably abutted against the outer side of the fixed drum 3 , thereby preventing the rotating drum 4 from moving horizontally relative to the fixed drum 3 .

[0030] In this embodiment, when in use, by placing the transmission shaft to be tested in the two rotating drums 4, and then starting the four cylinders 7 through the controller 10, the upper clamping plate 5, the lower clamping plate 6 and the washer 1502 are moved upward, so that the upper clamping plate 5, the lower clamping plate 6 and the washer 1502 are in contact with the outer side of the transmission shaft, thereby clamping the transmission shaft; Then, the hydraulic cylinder 8 is started to control the driving plate 12 to move upward. The driving plate 12 drives the two rotating drums 4 to rotate in opposite directions through the two arc-shaped connecting plates 14, thereby applying torsional forces in different directions to the two ends of the transmission shaft. When slippage occurs between the transmission shaft and the clamp, the upper clamping plate 5 and the lower clamping plate 6 will rotate relative to the transmission shaft, and then the friction between the transmission shaft and the washer 1502 drives the rotating wheel 1501 and the screw rod 15 to rotate. The screw rod 15 drives the rotating column 1503 to rotate. The rotating column 1503 pushes the pressing plate 16 to move to the side close to the trigger button 17 through the contact between the arc-shaped protrusion 15031 and the push rod 1601. After being pressed, the trigger button 17 controls the operation of the cylinder 7, so that the driving force at the output end of the cylinder 7 is used to increase the clamping force on the transmission shaft, so that the clamping force on the transmission shaft can be gradually increased as the transmission shaft slips to meet the demand; When the driving plate 12 moves upward, the two second conductive sheets 34 will be driven upward, so that the first conductive sheet 33 and the second conductive sheet 34 are attached to each other, so that the signal light 13 is powered on and lights up, and the lifting operator test is completed. The hydraulic cylinder 8 can be controlled by the controller 10 to stop feeding, and the maximum torque that the transmission shaft can withstand can be calculated by checking the maximum pressure value monitored by the pressure sensor 9. When the driving plate 12 rises, the compression spring 35 is compressed, and slippage occurs between the transmission shaft and the clamp, so that when the screw rod 15 rotates, the slide plate 18 is driven to move laterally through the threaded transmission with the slide plate 18. The slide plate 18 drives the annular plate 20 to move laterally through the lateral movement with the guide frame 19. The annular plate 20 drives the connecting frame 22 to move laterally synchronously, and drives the cross bar 25 and the connecting column 26 to move laterally through the vertical plate 23. The connecting column 26 pushes the card plate 28 to move laterally by abutting against the vertical protrusion, so that the card plate 28 is disengaged from the card slot, thereby releasing the fixation of the mounting plate 32, so that the compression spring 35 can stretch and push the mounting plate 32 to move upward until it contacts the retaining ring again, thereby making the first conductive sheet 33 and the second conductive sheet 33 move laterally. After the spacing of the conductive sheets 34 is restored and the cross bar 25 continues to move laterally, the triangular plate 27 pushes the cross bar 25 and the connecting column 26 to move upward by abutting against the connecting column 26, so that the vertical protrusion is out of contact with the connecting column 26, and the card plate 28 is reset under the action of the connecting spring 29 and is inserted into another card slot to fix the mounting plate 32. When the transmission shaft continues to slip, the continued lateral movement of the slide plate 18 will drive the card plate 28 to move laterally again to release the fixation of the positioning plate 31 and the mounting plate 32, so that the second conductive sheet 34 cannot contact the first conductive sheet 33, until the transmission shaft does not slip, the card plate 28 will not fall out of the card slot, and the second conductive sheet 34 can contact the first conductive sheet 33, so as to remind the detection work to stop; And because a control button 30 is provided on the top inner wall of the lateral groove, when the mounting plate 32 moves up to contact with the control button 30, the clamping force of the clamp is still not enough to prevent the transmission shaft from slipping. The control button 30 is pressed to control the hydraulic cylinder 8 to stop feeding, and the detection device can be reset, and the initial output pressure of the cylinder 7 can be adjusted to re-clamp the transmission shaft to meet the needs and avoid the transmission shaft slipping due to loose clamping, which affects the detection result.

The description of the above embodiments is only used to help understand the method of the present invention and its core idea. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
