Description

Technical Field

[0001] This utility model relates to the field of transmission shaft bending correction technology, and in particular to a transmission shaft bending correction device. Background Technology

[0002] In the process of car repair, especially for heavy vehicles, drive shafts may become bent due to long-term use or collisions. Bending correction devices can be used to repair these bent drive shafts and restore their original working performance.

[0003] The existing patent document CN219401793U discloses a bending machine correction device, comprising: a bending machine body, a first cylinder housing and a second cylinder housing fixedly installed on the left and right side walls of the bending machine body, a base plate fixedly installed between the first cylinder housing and the second cylinder housing, a transmission rotation mechanism provided on the right side of the first cylinder housing, and a telescopic mechanism provided on the right side of the transmission rotation mechanism. This invention, according to the required correction angle, drives the first and second connecting rods to rotate as a whole a certain number of times via a motor, then drives the transmission shaft to separate from the first connecting rod via a first electric telescopic rod, and locks the second connecting rod through a locking mechanism to prevent the second connecting rod from rotating and causing errors. The motor is then restarted, causing the motor to drive the first connecting rod in reverse rotation by the same number of times, completing the bending machine correction. This achieves automated correction and eliminates the need for manual adjustment.

[0004] The above method can achieve automatic correction, but it does not include a mechanism to fix the drive shaft that needs to be corrected, which makes the drive shaft prone to deviation during the correction process. Utility Model Content

At the same time, the double-section rotating plate and the single-section rotating plate connected by the long rotating plate and the rotating plate also rotate simultaneously. The three fixed wheels slide inward at the same time to fix the transmission shaft, ensuring that the transmission shaft remains stable during the correction process and will not affect the correction effect due to deviation.

Detailed Implementation

[0024] The embodiment of this application is as follows:

[0025] Please see Figures 1 to 3A drive shaft bending correction device includes a base plate 1, which serves as the base for the entire drive shaft bending correction device, providing support and stability. A support frame 2 is fixedly connected to the top of the base plate 1, which supports the internal mechanism of the fixing mechanism 3. The fixing mechanism 3 is fixedly connected to the front side of the support frame 2, which fixes the drive shaft in the device to prevent displacement during the correction process. A conveying ramp 18 is fixedly connected to the top of the base plate 1, which conveys the drive shaft to be corrected. A conveying mechanism 19 is fixedly connected to the top of the base plate 1, which is responsible for conveying the drive shaft to be corrected to the correct position so that it can be fixed and corrected after entering the fixing mechanism 3.

[0026] The fixing mechanism 3 includes a pushing assembly, which is the power source of the fixing mechanism 3. The pushing assembly includes a fixing block 4, the rear side of which is fixedly connected to the front side of the support frame 2. The fixing block 4 is used to fix the cylinder 5. The front side of the fixing block 4 is fixedly connected to the cylinder 5. The cylinder 5 outputs power to drive the rotation of the double-section rotating rod 6. The pushing assembly is fixedly connected to the double-section rotating plate 6. The inner side of the double-section rotating plate 6 is rotatably connected to the connecting block 7. The double-section rotating plate rotates under the drive of the cylinder 5, causing the inner connecting block 7 to rotate together. The front side of the connecting block 7 is fixedly connected to the cylinder 6. A sliding block 8 is fixedly connected to the front of the sliding block 8, and a fixed wheel 9 is fixedly connected to the front of the sliding block 8. The rotation of the connecting block 7 causes the sliding block 8 and the fixed wheel 9 to slide inward. A sliding rail 10 is fixedly connected to the front of the support frame 2. When the double-section rotating plate and the connecting block 7 rotate, the sliding rail 10 transmits power to the sliding block 8 and the fixed wheel 9. The sliding block 8 and the fixed wheel 9 are restricted within the sliding rail 10, converting rotation into sliding. A transmission assembly is fixedly connected to the top of the double-section rotating plate 6. The transmission assembly is used to transmit the power of the pushing assembly, causing the three fixed wheels 9 to slide inward simultaneously.

[0027] The transmission assembly includes a long rotating plate 11, the bottom of which is fixedly connected to the top of a double-section rotating plate 6. A second double-section rotating plate 12 is fixedly connected to the top of the long rotating plate 11. The inner side of the second double-section rotating plate 12 is rotatably connected to the outer side of the connecting block 7. The long rotating plate 11 transmits power from the first double-section rotating plate to the second double-section rotating plate 12, which in turn drives the connecting block 7 to rotate. A sliding block 8 and a fixed wheel 9 slide within a sliding track 10. A second long rotating plate 13 is fixedly connected to the bottom of the second double-section rotating plate 12. A single-section rotating plate 14 is fixedly connected to the inner side of the second long rotating plate 13. The inner side of the single-section rotating plate 14 is rotatably connected to the outer side of the connecting block 7. Rotating plate 13 transmits the power of double-section rotating plate 12 to single-section rotating plate 14, which in turn drives connecting block 7 to rotate. Sliding block 8 and fixed wheel 9 slide within sliding track 10. The three fixed wheels 9 slide inward simultaneously to fix the drive shaft. Multiple placement racks 15 are fixedly connected to the top of base plate 1. The placement racks 15 are used to place the drive shaft when it is being corrected. Fixed frame 16 is fixedly connected to the top of base plate 1. Correction device body 17 is fixedly connected to the bottom of fixed frame 16. Fixed frame 16 provides additional stability. Correction device body 17 is fixedly connected to the bottom. The function of correction device body 17 is to provide precise correction force to correct the drive shaft.

[0028] please Figure 1 , Figure 4 and Figure 5The conveying mechanism 19 includes a conveying platform 20, the bottom of which is fixedly connected to the top of the base plate 1. A fixed triangular plate 21 is fixedly connected to the top of the conveying platform 20. The conveying platform 20 is a platform for conveying the drive shaft. The fixed triangular plate 21 and the sliding triangular plate 26 work together to convey the drive shaft. A cylinder 22 is fixedly connected inside the conveying platform 20. A drive block 23 is fixedly connected to the output end of the cylinder 22. The cylinder outputs power through the drive block 23 to drive the sliding ramp 24 to slide. The sliding ramp 24 is fixedly connected to the drive block 23. The bottom of the sliding ramp 24 is in contact with the top of the conveying platform 20. After the sliding ramp 24 slides towards the cylinder 22, it reaches the bottom of the rotating wheel 27 at a higher slope. The rotating wheel 27 slides on the surface of the sliding ramp 24, thereby driving the connecting plate 25 and the top sliding triangular plate 26 to rise. The drive shaft is then locked in place by the fixed triangular plate 21. Inside the sliding triangle 26, the transmission shaft is conveyed by the repeated lifting of the sliding triangle 26. A connecting plate 25 is slidably connected inside the conveying table 20. The top of the connecting plate 25 is fixedly connected to the sliding triangle 26. The connecting plate 25 and the sliding triangle 26 are lifted by the contact between the bottom of the rotating wheel 27 and the surface of the sliding ramp 24. The bottom of the connecting plate 25 is fixedly connected to the rotating wheel 27, and the bottom of the rotating wheel 27 is rotatably connected to the top of the sliding ramp 24. The rotating wheel 27 and the sliding ramp 24 work together to lift the transmission shaft. Multiple sliding rods 28 are fixedly connected to the bottom of the connecting plate 25. Multiple sliding housings 29 are fixedly connected inside the conveying table 20. When the connecting plate 25 and the sliding triangle 26 slide up and down, the sliding rods 28 also slide up and down inside the sliding housings 29 to maintain the stability of the connecting plate 25 and the sliding triangle 26 during the sliding process.

[0029] In this specific embodiment, during use, when the drive shaft reaches the fixing mechanism 3, the cylinder 5 on the fixing block 4 is activated, outputting power to drive the double-section rotating plate 6 to rotate. The connecting round block 7 on the inner side of the double-section rotating plate 6 rotates accordingly, thereby driving the sliding block 8 and the fixed wheel 9 to slide inward in the sliding track 10. At the same time, the long rotating plate 11 at the top of the double-section rotating plate 6 transmits power to the double-section rotating plate 12. The double-section rotating plate 12 drives the connecting round block 7 on the other side to rotate through the long rotating plate 13 and the single-section rotating plate 14, causing the corresponding sliding block 8 and the fixed wheel 9 to slide inward as well. Finally, the three fixed wheels 9 slide inward simultaneously, firmly fixing the drive shaft. After the drive shaft is fixed, it is placed on the placement frame 15 for correction. The main body 17 of the correction device at the bottom of the fixing frame 16 is activated, applying a precise correction force to the drive shaft to complete the bending correction operation.

[0030] The drive shaft to be corrected slides down the conveyor ramp 18 onto the conveyor platform 20 of the conveyor mechanism 19. The cylinder 22 inside the conveyor platform 20 is activated, and the sliding ramp 24 is driven to slide towards the cylinder 22 via the drive block 23. At this time, the higher slope of the sliding ramp 24 moves to the bottom of the rotating wheel 27. The rotating wheel 27 slides on the surface of the sliding ramp 24, thereby driving the connecting plate 25 and the top sliding triangle 26 to rise upward. The drive shaft is stuck inside the fixed triangle 21 and the sliding triangle 26. With the reciprocating action of the cylinder 22, the sliding ramp 24 slides continuously. The rotating wheel 27 drives the connecting plate 25 and the sliding triangle 26 to rise one after another, gradually conveying the drive shaft forward to the fixed mechanism 3. When the connecting plate 25 and the sliding triangle 26 slide up and down, the sliding rod 28 also slides up and down inside the sliding housing 29 to maintain the stability of the connecting plate 25 and the sliding triangle 26 during the sliding process.

[0031] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that implementing all or part of the above embodiments and making equivalent changes in accordance with the claims of this application still fall within the scope of this application.
