Description

Technical Field

[0001] The utility model relates to the technical field of half - shaft straightening, and particularly relates to a straightening device for an automobile half - shaft. Background Art

[0002] An automobile half - shaft straightening device is a tool used to correct and repair the bending or deformation of an automobile half - shaft. The half - shaft, also known as the drive shaft or transmission shaft, is an important component connecting the wheels and the gearbox, responsible for transmitting the power of the engine to the driving wheels of the automobile. The half - shaft bears a large amount of torque and force during vehicle driving, so it may be bent or damaged due to impacts, long - term use or other reasons. An automobile half - shaft straightening device usually includes components such as a straightening frame, straightening fixtures, and a control system. Through a precise straightening process, it ensures that the geometric shape and dimensions of the half - shaft meet the design requirements. Using such a device can not only extend the service life of the half - shaft, but also improve the overall performance and reliability of the automobile;

[0003] The Chinese patent authorization announcement number is CN218252241U, and the name is a straightening tool for an automobile half - shaft, including a workbench. A support plate is fixedly connected to the rear side of the workbench, a connecting block is fixedly connected to the top of the support plate, and a first sliding groove is opened at one end of the connecting block close to the workbench. Through the settings of the first servo - motor, the second servo - motor, the pressing head, the lead screw, the bidirectional lead screw, the electric cylinder, the straightening roller and the electric hydraulic cylinder, the first servo - motor drives the lead screw to rotate, thereby adjusting the pressing head to the bending position of the half - shaft. Then, according to the degree of bending of the half - shaft, the distance between the two straightening rollers is adjusted by the second servo - motor. Then, the electric hydraulic cylinder pushes the pressing head to drop, and the half - shaft is straightened under the action of the straightening roller and the pressing head, thereby improving the straightening accuracy;

[0004] The deficiencies of the above - mentioned scheme are as follows: Although the above - mentioned scheme can improve the straightening accuracy, the pressure of the pressing head may be too large during straightening. Excessive pressure may cause plastic deformation of the half - shaft material, and may also cause irregular geometric deformation in local areas of the half - shaft, affecting its dynamic balance and load - transfer ability. And there is no detection mechanism in the above - mentioned device to test the accuracy of the half - shaft. Without a detection mechanism, it is very difficult to accurately judge the degree and position of the deformation of the half - shaft, resulting in the technical problems that the straightening work may not be accurately executed and the straightening effect cannot be effectively verified. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a straightening device for an automobile half - shaft to solve the technical problems in the prior art that the pressure of the pressing head may be too large during straightening, excessive pressure may cause plastic deformation of the half - shaft material, and there is no detection mechanism in the above - mentioned device to test the accuracy of the half - shaft. Without a detection mechanism, it is very difficult to accurately judge the degree and position of the deformation of the half - shaft, and the straightening effect cannot be effectively verified.

[0027] An electric screw rod 3 is connected to the top plate 2. A sliding nut 4 is slidably connected to the electric screw rod 3. A connecting frame 5 is connected to the sliding nut 4. The connecting frame 5 is a steel structure body. A straightening mechanism is connected to the connecting frame 5. The straightening mechanism includes two connecting blocks 9. The two connecting blocks 9 are both connected to the connecting frame 5. An electric gear 10 is connected to each of the connecting blocks 9. A toothed ring 11 is meshed with the electric gear 10.

Two sliding rods 13 are connected to the fixing block 12. A sliding plate 14 is slidably connected to the sliding rods 13. A clamping block 15 is fixedly connected to the sliding plate 14. The clamping block 15 is an arc-shaped plate. A lubricant is coated on the clamping block 15. The moving rod 16 is arranged in cooperation with the clamping block 15;

[0028] A detection mechanism is arranged on the side of the straightening mechanism away from the clamping mechanism. The detection mechanism includes a fixing frame 8.

[0030] Such a design can enable the half shaft body 6 to receive a uniform force during the straightening process, thereby ensuring the accuracy and efficiency of straightening. Moreover, using the electric push rod and the electric gear 10 can conveniently control the magnitude and direction of the straightening force, improving the flexibility and safety of operation.
