Technical Field
[0001] The present invention relates to the technical field of transmission shaft detection, and in particular to a mechanical transmission shaft detection device. Background Art
[0002] The drive shaft is the shaft in the universal joint transmission that can transmit power. It is a high-speed, low-support rotating body, so its dynamic balance is very important. Generally, the drive shaft must undergo a dynamic balance test before leaving the factory and be adjusted on a balancing machine. For front-engine rear-wheel drive vehicles, it is the shaft that transmits the rotation of the transmission to the main reducer. It can be composed of several sections, and the sections can be connected by universal joints. A torsional strength detection device is required during the detection of the drive shaft.
[0003] The patent document with publication number CN215767654U discloses a heavy-duty vehicle drive shaft strength detection device, including a base, a box and a first fixed seat. Push handles are provided on the left and right sides of the base, and a base bracket is provided at the lower end of the base, and the lower end of the base bracket is connected to the base, and a universal wheel is provided at the lower end of the base. The box is provided at the upper end of the base, and a swing leaf is provided on the outside of the box.
[0004] In the above technical solution, the transmission shaft may slip against the chuck during the transmission shaft inspection process, which makes it easy for errors to occur in the transmission shaft load limit measured during the torsional strength test. In addition, the chuck may have rotated relatively but the transmission shaft has not undergone torsional deformation, causing the operator to misjudge.

[0018] The beneficial effects of the present invention are:
[0019] 1. In the present invention, a mechanical transmission shaft detection device is described, which is configured to place the transmission shaft to be detected in two rotating drums, and then activate four cylinders through a controller to drive the upper and lower clamping plates to move upward, so that the upper and lower clamping plates and washers fit the outer side of the transmission shaft, thereby clamping the transmission shaft;
[0020] 2. In the present invention, a mechanical transmission shaft detection device is described, and then the hydraulic cylinder is started to control the driving plate to move upward. The driving plate drives the two rotating drums to rotate in opposite directions through the two arc-shaped connecting plates, 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 and the lower clamping plate will rotate relative to the transmission shaft, and then the friction between the transmission shaft and the washer will drive the runner and the screw to rotate, and the screw drives the rotating column to rotate. The rotating column pushes the pressing plate to move to the side close to the trigger button through the contact between the arc-shaped protrusion and the push rod. After the trigger button is pressed, it will control the operation of the cylinder, so that the driving force at the output end of the cylinder 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 needs;
[0021] 3. In the present invention, the mechanical transmission shaft detection device described above drives the two second conductive sheets to move upward when the driving plate moves upward, so that the first conductive sheet and the second conductive sheet are in contact with each other, thereby turning on the signal light, indicating that the lifting operator test is complete. The hydraulic cylinder can be controlled by the controller to stop feeding, and the maximum torque that the transmission shaft can withstand can be calculated by observing the maximum pressure value monitored by the pressure sensor.
[0022] 4. In the present invention, a mechanical transmission shaft detection device is described, in which the driving plate compresses the compression spring when it rises, and when slippage occurs between the transmission shaft and the clamp so that the screw rotates, the slide plate is driven to move laterally through the threaded transmission with the slide plate, and the slide plate drives the annular plate to move laterally through the lateral movement with the guide frame, and the annular plate drives the connecting frame to move laterally synchronously, and drives the cross bar and the connecting column to move laterally through the vertical plate, and the connecting column pushes the card plate to move laterally by abutting with the vertical protrusion, so that the card plate is disengaged from the card slot, thereby releasing the fixation of the mounting plate, so that the compression spring can stretch and push the mounting plate to move upward until it contacts the retaining ring again, thereby When the cam is in the closed position, the first and second conductive plates are in the closed position, and the second conductive plate is in the closed position, so that the cam is in the closed position and the second conductive plate is in the closed position. When the cam is in the closed position, the cam is in the closed position, so that the cam is in the closed position and the second conductive plate is in the closed position. When the cam is in the closed position, the cam is in the closed position, so that the cam is in the closed position and the second conductive plate is in the closed position. When the cam is in the closed position, the cam is in the closed position, so that the cam is in the closed position, so that the cam is in the closed position.
[0023] 5. 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. 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. When the control button is pressed, the hydraulic cylinder stops feeding and the detection device is reset. The initial output pressure of the cylinder is adjusted to re-clamp the transmission shaft to meet the needs and avoid loose clamping that causes the transmission shaft to slip and affect the detection results.
[0024] 6. In the present invention, the mechanical transmission shaft detection device can gradually increase the clamping force when the transmission shaft slips during the detection process through a trigger mechanism to meet the needs, and can adapt to the surface roughness and size differences at both ends of the transmission shaft to make independent corresponding adjustments, avoiding inaccurate detection results caused by too small clamping force, and avoiding 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.

A groove is provided on the top of the lower splint 6, and a transverse groove is provided on the side wall of the groove. A first fixed plate 1504 and a second fixed plate 1603 are fixedly connected in the transverse groove. The first fixed plate 1504 is rotatably sleeved on the outer side of the screw rod 15, and the second fixed plate 1603 is slidably sleeved on the outer sides of the two push rods 1601. A return spring 1602 is fixedly connected between the second fixed plate 1603 and the pressing plate 16. A sliding groove is provided at the bottom of the lower splint 6, and the slide plate 18 is slidably connected in the sliding groove, and a limiting rod is fixedly installed in the sliding groove. The slide plate 18 is slidably sleeved on the outer side of the limiting rod, thereby guiding and limiting the slide plate 18.
[0045] In this embodiment, the top of the vertical plate 23 is fixedly connected to a positioning spring 21, and the top end of the positioning spring 21 is fixedly connected to the top inner wall of the corresponding connecting frame 22, thereby resetting the vertical plate 23, and one side of the connecting frame 22 is fixedly connected to a side rod 24, and the fixed tube 3 is slidably sleeved on the outside of the side rod 24.
[0046] In this embodiment, the top of the upper clamping plate 5 and the bottom of the lower clamping plate 6 are fixedly connected to the guide plate 401, and the rotating drum 4 is slidably sleeved on the outer side of the corresponding guide plate 401, thereby guiding the upper clamping plate 5 and the lower clamping plate 6.
[0047] 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 drive plate 12, and the drive 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.
[0048] 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.
[0049] 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 .
[0050] In this embodiment, when in use, the transmission shaft to be inspected is placed in the two rotating drums 4, and then the four cylinders 7 are activated by the controller 10 to drive the upper and lower clamping plates 6 to move upward, so that the upper and lower clamping plates 5 and 6 and the washer 1502 fit with the outer side of the transmission shaft, thereby clamping the transmission shaft;
[0051] 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 runner 1501 and the screw rod 15 to rotate, and 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 the trigger button 17 is pressed, it 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;
[0052] When the driving plate 12 moves upward, it drives the two second conductive plates 34 to move upward, so that the first conductive plate 33 and the second conductive plate 34 are in contact with each other, thereby turning on the signal light 13. The lifting operator test is then completed, and the hydraulic cylinder 8 can be controlled by the controller 10 to stop feeding. By checking the maximum pressure value monitored by the pressure sensor 9, the maximum torque that the transmission shaft can withstand can be calculated.
[0053] When the drive plate 12 rises, it compresses the compression spring 35, and slippage occurs between the transmission shaft and the clamp, causing the screw 15 to rotate. 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 slot, thereby releasing the fixation of the mounting plate 32, allowing the compression spring 35 to 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. When the spacing between 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 post 26 upward by abutting against the connecting post 26, so that the vertical protrusion is out of contact with the connecting post 26, and the card plate 28 is reset under the action of the connecting spring 29 and is snapped 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 again drive the card plate 28 to move laterally 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 stops slipping, 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.
[0054] 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 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 results.
