The right end of the shaft-type part 12 is clamped and fixed on the three-jaw chuck 10. The drive assembly includes a pad 6, an electric push rod 7, and a motor 11. The pad 6 is fixedly mounted on the top right side of the machine base 1, and the electric push rod 7 is fixedly mounted on the top of the pad 6.

The output shaft end of motor 11 is fixedly connected to the right end of rotating shaft 9. Three-jaw chuck 10 is used to clamp and fix shaft parts 12. Electric push rod 7 can push vertical plate 8 to move horizontally and linearly, which facilitates the adjustment of the position of shaft parts 12. Motor 11 is used to control the rotation of rotating shaft 9 and three-jaw chuck 10, so that the clamped and fixed shaft parts 12 can follow the rotation, thereby greatly improving the feeding efficiency, reducing manual operation steps, and improving the overall work efficiency.
[0027] In this embodiment, two guide rails 13 are fixedly installed on the top of the machine base 1, and the bottom of the vertical plate 8 is slidably mounted on the two guide rails 13. The two guide rails 13 serve to guide the movement direction of the vertical plate 8, making the vertical plate 8 move more stably and smoothly on the machine base 1.
[0028] In this embodiment, a support seat 2 and a U-shaped beam 4 are fixedly installed on the top of the machine base 1. The support seat 2 is located on the left side of the clamping and feeding mechanism, and the U-shaped beam 4 is located on the left side of the support seat 2. A first straightening mechanism 3 is installed on the support seat 2, and a second straightening mechanism 5 is installed on the U-shaped beam 4. The first straightening mechanism 3 and the second straightening mechanism 5 are used to straighten the shaft part 12. By utilizing the cooperation of the first straightening mechanism 3 and the second straightening mechanism 5, the shaft part 12 can be straightened from the vertical and horizontal directions respectively, and it can be ensured that the shaft part 12 will not shift during the straightening process, thereby improving the straightening accuracy of the shaft part 12. The first straightening mechanism 3 includes two support seats. 31. Two cylinders 32, two U-shaped plates 33, two connecting shafts 34, and two vertical straightening rollers 35. Two support seats 31 are fixedly mounted on the top of the bearing seat 2. Two cylinders 32 are respectively fixedly mounted on the top of their corresponding support seats 31. Two U-shaped plates 33 are respectively fixedly mounted on the output shaft ends of their corresponding cylinders 32, and the two U-shaped plates 33 are symmetrically arranged. Two connecting shafts 34 are rotatably mounted within their corresponding U-shaped plates 33. Two vertical straightening rollers 35 are respectively fixedly fitted onto their corresponding connecting shafts 34. The diameter of the vertical straightening rollers 35 gradually decreases from both ends towards the middle. Shaft-like parts 12 are located on two... Between the vertical straightening rollers 35, and with both vertical straightening rollers 35 in contact with the shaft parts 12, the retractable features of the two cylinders 32 can be used to control the horizontal linear movement of the corresponding U-shaped plates 33, thereby adjusting the distance between the two vertical straightening rollers 35. This is suitable for straightening shaft parts 12 of different diameters. The straightening mechanism 2 5 includes two cylinders 2 51, two U-shaped plates 2 52, two connecting shafts 2 53, and two horizontal straightening rollers 54. The two cylinders 2 51 are respectively fixedly installed on the top of the machine base 1 and the top inner wall of the U-shaped beam 4, and the two U-shaped plates 2 52 are respectively fixedly installed on the output of the corresponding cylinders 2 51. At the shaft end, two U-shaped plates 52 are symmetrically arranged, and two connecting shafts 53 are rotatably installed in the corresponding U-shaped plates 52. Two horizontal straightening rollers 54 are fixedly mounted on the corresponding connecting shafts 53. The diameter of the horizontal straightening rollers 54 gradually decreases from both ends to the middle. The shaft part 12 is located between the two horizontal straightening rollers 54, and both horizontal straightening rollers 54 are in contact with the shaft part 12. By utilizing the telescopic feature of the two cylinders 51, the horizontal linear movement of the corresponding U-shaped plates 52 can be controlled respectively, thereby adjusting the distance between the two horizontal straightening rollers 54. This method is suitable for straightening shaft parts 12 of different diameters.
[0029] In this embodiment, the vertical straightening roller 35 and the horizontal straightening roller 54 are set with the same shape and size, which further ensures the accuracy of the straightening process of the shaft part 12. The diameter of the vertical straightening roller 35 and the horizontal straightening roller 54 gradually decreases from both ends to the middle. This special design allows the vertical straightening roller 35 and the horizontal straightening roller 54 to apply straightening force to different parts of the shaft part 12 more accurately when they come into contact with the shaft part 12, effectively improving the straightening accuracy and ensuring that the shaft part 12 meets the high precision requirements.
[0030] In this embodiment, the top of the support base 2 has two guide grooves, and the bottoms of the two U-shaped plates 33 are slidably installed in the corresponding guide grooves, which guides the movement direction of the two U-shaped plates 33, making the movement and use of the two U-shaped plates 33 more stable.
[0031] In this embodiment, a mounting hole is provided on one side of the vertical plate 8, and the rotating shaft 9 is rotatably installed in the mounting hole through a bearing, which makes the rotation of the rotating shaft 9 more stable and smooth.
[0032] In this embodiment, it should be noted that a controller is fixedly installed on the outer wall of the machine base 1. The controller is equipped with multiple control buttons. The electric push rod 7, motor 11, cylinder 1 32, cylinder 2 51 and the controller are electrically connected. The multiple control buttons are used to control the power supply and operation of the electric push rod 7, motor 11, cylinder 1 32 and cylinder 2 51 respectively. The wiring connection method and control method are mature technologies in the field and are fully disclosed. Therefore, they will not be described in detail here.
[0033] Based on the above structure, the working principle of the automatic straightening device for shaft parts provided in this application is as follows:
[0034] First, securely clamp one end of the shaft part 12 onto the three-jaw chuck 10 to make the shaft part 12 horizontal. Then, start the motor 11 to drive the rotating shaft 9, the three-jaw chuck 10 and the clamped shaft part 12 to rotate. Next, control the electric push rod 7 to extend and run. Its output shaft pushes the vertical plate 8 to slide horizontally and linearly along the guide rail 13 at the top of the machine base 1 and gradually approach the straightening mechanism 3.
[0035] When the end of the shaft part 12 away from the three-jaw chuck 10 is sent to the working position of the straightening mechanism, the two cylinders 32 on the top of the bearing seat 2 are extended and operated by starting the cylinders. Their output shafts push the corresponding U-shaped plate 33 to move, so that the two vertical straightening rollers 35 gradually approach each other until the two vertical straightening rollers 35 contact the shaft part 12. Then the operation of the two cylinders 32 is stopped. Subsequently, in the process of controlling the shaft part 12 to move and rotate at a constant speed, the shaft part 12 will gradually pass between the two vertical straightening rollers 35. According to the degree of bending of the part, different pressures are applied to different parts to straighten the shaft part 12 in the vertical direction.
[0036] Next, after the vertical straightening process is completed, the shaft part 12 is sent to the working position of the straightening mechanism. By controlling the extension of the two cylinders 51, their output shafts push the corresponding U-shaped plate 52 to move, so that the two horizontal straightening rollers 54 gradually approach each other. When the two horizontal straightening rollers 54 contact the shaft part 12, the operation of the two cylinders 51 is stopped. Then, while continuing to control the shaft part 12 to move and rotate at a constant speed, the shaft part 12 will gradually pass between the two horizontal straightening rollers 54. When the two horizontal straightening rollers 54 contact the shaft part, they can apply a straightening force to the shaft part 12 from the horizontal direction, further straightening the shaft part 12. Thus, through the combined action of the two vertical straightening rollers 35 and the two horizontal straightening rollers 54, it can be ensured that the shaft part 12 can achieve high-precision straightness requirements in all directions, and it can be ensured that the shaft part 12 will not shift during the automatic straightening process, thus improving the straightening accuracy of the shaft part 12.
[0037] After the shaft part 12 is straightened, stop the motor 11 and control the two cylinders 32 and 51 to retract and reset. Then control the electric push rod 7 to retract and reset, so that the straightened shaft part 12 can be disassembled and removed.
