[0002] With the advancement of the machinery industry, particularly the booming development of industries like modern automobiles, textiles, and oil drilling, large quantities of shaft products are being used extensively. The drive shaft is a crucial component in the automotive transmission system, working with the gearbox and drive axle to transmit engine power to the wheels, generating propulsion. During the production and processing of drive shafts, their slender structure can easily lead to misalignment for various reasons, necessitating the use of straightening devices.
[0003] According to a Chinese patent with the announcement number CN219211385U, a transmission shaft straightening device is disclosed. The transmission shaft straightening device is provided with a control component. When it is necessary to fix transmission shafts of different calibers, the transmission shaft is placed on the arc plate on the surface of the fixed column, and the electric push rod drives the clamping plate to move in the direction of the arc plate to fix the transmission shaft. The pressure rod is supported by the transmission shaft and moves under the support of the spring. The support rod hinged on the surface of the pressure rod pushes the slide plate to move, and the clamping rod is clamped into the clamping teeth in the rack. It is fixed by the clamping block, which can avoid the situation where the transmission shaft is damaged due to excessive clamping during the clamping process.
[0004] With regard to the above-mentioned disclosed patent content, after the straightening of the drive shaft is completed, it is necessary to operate the clamping mechanism so that the clamping mechanism no longer clamps and fixes the drive shaft, and then remove the straightened drive shaft, and then place the drive shaft to be straightened between the clamping mechanisms, and then fix it by the clamping mechanism. The disassembly and installation process is relatively cumbersome and takes a lot of time, which makes it difficult for the device to quickly straighten the next drive shaft to be straightened, thereby reducing the straightening efficiency of the drive shaft.

The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0036] The following describes an embodiment of the present invention based on its overall structure.
[0037] Example 1:
[0038] A transmission shaft straightening device, such as Figures 1-6 As shown, it includes a base plate 1, vertical plates 2 are installed on both sides of the top of the base plate 1, a rotating component 9 is provided on the vertical plate 2, a top plate 3 is provided on the top of the vertical plate 2, a first motor 7 is installed on one side of the top of the top plate 3, and the output end of the first motor 7 is connected to the screw rod 5. If the straightening block 10 needs to be moved laterally, the first motor 7 can be started. The first motor 7 can drive the screw rod 5 to rotate, and then drive the movable seat 6 to move. The outer wall of the screw rod 5 is sleeved with the movable seat 6, and a hydraulic cylinder 8 is installed at the bottom of the movable seat 6, and the output end of the hydraulic cylinder 8 is installed with the straightening block 10 through the piston rod. When the drive shaft needs to be straightened, the hydraulic cylinder 8 can be started to cause the piston rod to contract, thereby driving the straightening block 10 to move up and down, which is convenient for straightening the drive shaft.
[0039] See Figure 1-Figure 4The top plate 3 passes through the movable seat 6, and the movable seat 6 is threadedly connected to the screw rod 5. When the screw rod 5 rotates, it will drive the movable seat 6 to move, and the movable seat 6 will drive the hydraulic cylinder 8 to move. At the same time, the top plate 3 can guide the movable seat 6 to prevent the movable seat 6 from rotating. A fixed plate 4 is connected to the other side of the top of the top plate 3, and one end of the screw rod 5 is connected to the fixed plate 4 through a bearing. The setting of the fixed plate 4 can support the screw rod 5, thereby improving the stability of the screw rod 5 when it rotates.
[0040] Specifically, the rotating assembly 9 includes a through hole 901 opened on the two vertical plates 2 and a second motor 907 installed on one side of the top of the bottom plate 1. The inner wall of the through hole 901 is provided with a movable groove 903, and a plurality of movable blocks 902 are provided inside the movable groove 903. The movable groove 903 is in a ring shape. The movable blocks 902 are slidably connected with the movable groove 903 so that the movable blocks 902 slide inside the movable groove 903, thereby improving the stability of the turntable 904 when rotating. A turntable 904 is installed between the plurality of movable blocks 902. After the root transmission shaft is straightened, the second motor 907 is started. The second motor 907 drives the gear 908 to rotate, which in turn drives the outer ring gear 906 to rotate, and then drives the turntable 904 to rotate. Two fixed cylinders 905 are installed on one side of the turntable 904, and the outer ring gear 906 is installed on the outer wall of the turntable 904. The output end of the second motor 907 is connected to the gear 908, and the gear 908 is engaged with the outer ring gear 906. When the second motor 907 is working, it can drive the gear 908 to rotate, and the gear 908 drives the outer ring gear 906 to rotate.
[0041] Specifically, a fixing frame 11 is provided at the top and bottom of the fixing cylinder 905, and a threaded rod 12 is threadedly connected to the fixing frame 11, and one end of the threaded rod 12 extends to the inside of the fixing cylinder 905 and is connected to a splint 13 through a bearing. If the splint 13 needs to be moved and the transmission shaft needs to be clamped, the threaded rod 12 can be rotated to move the threaded rod 12 and drive the splint 13 to move. An anti-slip pad 15 is installed on the inner wall of the splint 13, and the threaded rod 12 is threadedly connected to the fixing cylinder 905. The other end of the threaded rod 12 is connected to a knob. When the end of the transmission shaft needs to be clamped, the threaded rod 12 can be rotated by the knob to move the threaded rod 12 and drive the splint 13 to move.
[0042] Example 2:
[0043] On the basis of the above-mentioned embodiment 1, in order to improve the stability of the clamping plate 13 during movement and prevent the clamping plate 13 from rotating along with the threaded rod 12, it is necessary to guide it, and thus the following structure is provided.
[0044] See Figure 2-Figure 4 The splint 13 is provided with a guide rod 14 that passes through the outside of the fixed tube 905. When the splint 13 moves, it will drive the guide rod 14 to move, and the guide rod 14 can guide the splint 13 to prevent the splint 13 from rotating.
[0045] The working principle of the present utility model is as follows: first, the staff installs the device and turns on the power supply, then passes the transmission shaft through the fixed cylinder 905 on one side, and inserts the other end of the transmission shaft into the inside of the other fixed cylinder 905, then rotates the threaded rod 12, so that the threaded rod 12 moves and drives the clamping plate 13 to move, and the clamping plate 13 clamps the end of the transmission shaft, and then starts the hydraulic cylinder 8, so that the straightening block 10 moves up and down, so as to straighten the transmission shaft;
[0046] After the straightening of one transmission shaft is completed, the hydraulic cylinder 8 is started to move the straightening block 10 upward and reset, and then the second motor 907 is started. The second motor 907 drives the driving gear 908 to rotate, and then drives the outer gear ring 906 to rotate, and then drives the turntable 904 to rotate. The turntable 904 drives the two fixed cylinders 905 to rotate 180°, so that the straightened transmission shaft is rotated to the other side, and the other transmission shaft to be straightened is rotated to the bottom of the straightening block 10, so that the next transmission shaft can be straightened quickly. In the process of straightening the transmission shaft, the staff can remove the other straightened transmission shaft and insert the transmission shaft to be straightened into the fixed cylinder 905 for fixation, so that it can be quickly rotated to the bottom of the straightening block 10 for straightening.
