Description

Technical Field

[0001] This invention relates to the field of transmission shaft testing, and in particular to an intelligent testing device for the torsional strength of a motor transmission shaft. Background Technology

[0002] As an important component in mechanical equipment, the shaft plays a crucial role in power transmission and guidance. The operating conditions of transmission shafts vary in different transmission devices, and torsional tests can be conducted to detect and assess their torsional strength.

[0003] In related technologies, the torsional strength testing device for motor drive shafts generally uses a positioning clamping mechanism to first position both ends of the drive shaft to ensure that the drive shaft does not rotate. One of the positioning clamping mechanisms is usually equipped with a torque detection component (torque sensor), and the other positioning clamping mechanism is connected to the output shaft of the drive mechanism that drives its rotation. During the test, the drive mechanism drives the drive shaft to have a tendency to be driven to rotate, and then the torque detection component detects the torque strength.

[0004] However, existing torsional strength testing devices for motor drive shafts generally require removing the tested workpiece after the test is completed and then fixing the workpiece to be tested before continuing the test. This continuous testing process requires too much manual intervention, resulting in low loading and unloading efficiency and thus affecting the testing efficiency.

[0005] Therefore, it is necessary to propose an intelligent detection device for the torsional strength of motor drive shafts to solve the above problems. Summary of the Invention

[0024] Beneficial effects

[0025] Compared with the prior art, the present invention provides an intelligent detection device for the torsional strength of a motor drive shaft, which has the following advantages:

[0026] 1. The intelligent torsional strength detection device for the motor drive shaft uses a positioning and clamping mechanism to facilitate the positioning and clamping of the drive shaft. The electric push rod facilitates the displacement of the moving frame, thereby facilitating the release of one end of the drive shaft from the positioning and clamping mechanism on the fixed frame after testing. The ejection mechanism facilitates the ejection of the other end of the drive shaft from the positioning and clamping mechanism on the torque detection component. The loading and unloading mechanism is linked to the movement of the moving frame, enabling the loading and unloading of the drive shaft while the moving frame is moving. The structure is simple and compact, with high loading and unloading efficiency, improving the efficiency of continuous production and increasing practicality. The coordinated design of the guide plate and the receiving groove facilitates the collection and reception of the tested drive shaft.

[0027] 2. The intelligent detection device for the torsional strength of the motor drive shaft, through the cooperation of the set convex strip, sealing plate, pulling plate and second spring, can make the drive shaft at the bottom of the storage cylinder fall when the workpiece receiving port passes the bottom of the storage cylinder. When the bottom of the storage cylinder is misaligned with the workpiece receiving port, the bottom of the storage cylinder can be sealed to avoid the drive shaft in the storage cylinder from rubbing against the outer surface of the loading and unloading rollers and causing damage.

[0047] As a preferred embodiment, the loading and unloading mechanism includes a pair of support frames 14 disposed between the fixed frame 3 and the movable frame 4. Loading and unloading rollers 9 are rotatably connected between the two support frames 14 via a second rotating shaft 15.

A round shaft 10 is fixedly connected to one end of the second rotating shaft 15 near the movable frame 4.

Straight grooves 31 parallel to the axis of the round shaft 10 are evenly arranged circumferentially on the outer side of the round shaft 10.

A connecting arm 16 is provided on the side of the movable frame 4 facing the circular shaft 10. A groove 23 is provided on the side of the connecting arm 16 away from the movable frame 4. A pin 24 is movably mounted in the groove 23. One end of the pin 24 protrudes from the side of the connecting arm 16 and is rotatably connected to a guide wheel 22 that is movably connected to the straight groove 31 and the inclined groove 32. In the detection state, the guide wheel 22 is located inside the straight groove 31 near the loading and unloading rollers 9. When the movable frame 4 moves away from the fixed frame 3 to the limit distance, the guide wheel 22 is located at the end of the straight groove 31 near the movable frame 4. At this time, the guide wheel 22 corresponds to the first inclined surface 33 and the second step 35 and is located between the second step 35 and the first inclined surface 33. The inner end of the groove 23 is provided with a first spring 25. The top of the base 1 is inclined on one side and is provided with a storage cylinder 8 corresponding to the loading and unloading rollers 9 and used for stacking and storing the transmission shaft. The lower end of the storage cylinder 8 is an arc shape adapted to the outer side of the loading and unloading rollers 9.

[0048] Furthermore, a blocking plate 28 for blocking the drive shaft is movably inserted into one side of the lower end of the storage cylinder 8. One end of the blocking plate 28 extends outward and is fixedly connected to a traction plate 29 arranged perpendicular to the blocking plate 28. A second spring 30 is fixedly connected between one side of the traction plate 29 and the outer wall of the storage cylinder 8.

[0049] Furthermore, a collection mechanism is provided at one end of the top of the base 1. The collection mechanism includes a receiving groove 11 located on the top of the base 1 away from the storage cylinder 8. A guide plate 12 is inclined above the receiving groove 11, and the upper end of the guide plate 12 corresponds to the lower side of the loading and unloading rollers 9, while the lower end of the guide plate 12 corresponds to one end of the top of the receiving groove 11.

[0050] In addition, a protective cover 2 is provided above the base 1 of the device, and the upper end of the storage cylinder 8 extends to the top of the protective cover 2. A controller that is electrically connected to the electric push rod 13, the motor 6, and the rotary cylinder 36 is provided on the protective cover 2.

[0051] Working principle: During use, the drive shafts to be tested are stacked and stored in the storage cylinder 8, with the bottom blocked by the sealing plate 28. At this time, the distance between the moving frame 4 and the fixed frame 3 is at its maximum. The guide wheel 22 is located at one end of one of the straight grooves 31 near the moving frame 4, and the gripper 20 is in the open state. When testing is required, the controller on the protective cover 2 controls the electric push rod 13. The electric push rod 13 drives the moving frame 4 to move towards the fixed frame 3, and then the connecting arm 16 on the moving frame 4 drives the guide wheel 22 to move. Under the action of the second step 35 and the inclined surface 33, the guide wheel 22 enters an adjacent inclined groove 32 from the end of the straight groove 31, and the guide wheel 22 will drive the pin 24 to compress the first... After the spring 25 and guide wheel 22 enter the inclined groove 32, they will drive the round shaft 10 to rotate. The round shaft 10, in turn, drives the loading and unloading rollers 9 to rotate via the second rotating shaft 15. When the guide wheel 22 quickly moves to the other end of the inclined groove 32, the protrusion 27 abuts against the pulling plate 29. The pulling plate 29 then drives the sealing plate 28 to move and stretch the second spring 30. Afterward, the bottom of the storage cylinder 8 is unsealed, and the lowest drive shaft in the storage cylinder 8 falls into the corresponding workpiece receiving port 26. After the protrusion 27 separates from the pulling plate 29, the second spring 30 resets. The sealing plate 28 automatically seals the bottom of the storage cylinder 8. The guide wheel 22 continues to move in the inclined groove 32. When the guide wheel 22 just moves from the inclined groove 32 to the straight groove 31, the drive shaft is being accommodated... The workpiece receiving opening 26 is located at the top center of the loading and unloading rollers 9. At this time, the two ends of the drive shaft correspond to the two positioning and clamping mechanisms respectively. Due to the presence of the first step 34, after the guide wheel 22 enters the straight groove 31, the first spring 25 resets, and then the guide wheel 22 resets. Then, the moving frame 4 drives the guide wheel 22 to continue to move. The guide wheel 22 will move in the direction of the loading and unloading rollers 9 in the straight groove 31. Then, the push plate 21 on the moving frame 4 will push one end of the drive shaft into the positioning and clamping mechanism on the fixed frame 3. As the displacement proceeds, the drive shaft remains stationary. The push plate 21 begins to compress the third spring 42 inside the cylinder 40 through the inner rod 41 until the end of the drive shaft near the moving frame 4 enters the positioning and clamping mechanism on the moving frame 4. At this time, the guide wheel 22 is located at one end of the straight groove 31 near the loading and unloading rollers 9. Then, the rotary cylinder 36 drives the rotating seat 37 to rotate. The rotating seat 37 drives the telescopic rod 39 to move inward through the pull rod 38. The telescopic rod 39 drives the clamp 20 to position and clamp the two ends of the transmission shaft securely through the clamp connecting arm 19. Then, the motor 6 is controlled, and after being reduced by the reducer 5, the positioning clamping mechanism on the fixed frame 3 is driven to rotate through the first rotating shaft 7. Consequently, the transmission shaft is driven to rotate. Then, the torque detection component 17 on the moving frame 4 detects the torque force. After the detection is completed, the positioning clamping mechanism on the fixed frame 3 first releases the transmission shaft. Then, the electric push rod 13 drives the moving frame 4 to move. The positioning clamping mechanism on the moving frame 4 drives the transmission shaft to move.Simultaneously, the movable frame 4 drives the guide wheel 22 to move in a rectangular position along the length of the circular shaft 10 in the straight groove 31 via the connecting arm 16. At this time, the loading and unloading rollers 9 and the circular shaft 10 do not rotate. As the guide wheel 22 moves in the straight groove 31, one end of the transmission shaft disengages from the positioning and clamping mechanism on the fixed frame 3, and the guide wheel 22 contacts the second inclined surface 43 in the straight groove 31, thereby compressing the first spring 25. When the movable frame 4 moves to its limit distance, the guide wheel 22 is located at the end of the straight groove 31 closest to the movable frame 4. At this time, the guide wheel 22 and the second step 35... Corresponding to the first inclined plane 33 and located between the first inclined plane 33 and the second step 35, it prepares for subsequent loading and unloading. Then, the positioning clamping mechanism on the moving frame 4 is released, the third spring 42 is reset, and then the push plate 21 pushes out the drive shaft. The drive shaft falls to the workpiece receiving port 26 at the top of the loading and unloading roller 9. Then, the moving frame 4 moves again towards the fixed frame 3, thereby realizing loading. The detected drive shaft falls down with the rotation of the loading and unloading roller 9 and falls into the receiving groove 11 for collection through the guide inclined plate 12. This device has a simple and compact structure, a high degree of automation, and improves efficiency.
