Technical Field

[0001] The utility model belongs to the technical field of knuckle processing, and particularly relates to an axial positioning anti-misalignment device for knuckle processing. Background Technique

[0002] The knuckle is a key component in the automotive steering system, and it is usually located between the wheel and the steering mechanism. The main function of the knuckle is to transmit the steering force generated by the steering mechanism to the wheel, so as to make the wheel turn.

[0003] In the current field of automotive parts processing, especially in the process of knuckle processing, the application of axial positioning anti-misalignment devices has become an important means to ensure processing accuracy and quality. However, traditional axial positioning anti-misalignment devices have certain limitations when dealing with knuckles of different shapes and sizes. Specifically, these devices usually need to be equipped with clamping blocks of corresponding shapes according to the specific shape of the knuckle for clamping and positioning. Although this method can achieve accurate positioning, there is a problem: when processing knuckles of different models, it is necessary to replace the matching clamping blocks. This process not only consumes a lot of time and labor, but also reduces the flexibility and efficiency of the production line and increases the production cost. Therefore, seeking a more efficient and adaptable axial positioning anti-misalignment device has become a key requirement in the improvement of knuckle processing technology. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide an axial positioning anti-misalignment device for knuckle processing, so as to solve the problem that when processing knuckles of different models, it is necessary to replace the matching clamping blocks, which not only consumes a lot of time and labor, but also reduces the flexibility and efficiency of the production line and increases the production cost as mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: An axial positioning anti-misalignment device for knuckle processing, including a base, a fixed seat and a sliding seat. One end of the upper surface of the base is fixedly connected with a fixed seat. Both ends of the inner surface of the fixed seat are provided with first rotating grooves. The inside of the first rotating grooves is rotationally connected with first rotating seats. Both ends of the inner surface of the first rotating seats are provided with second rotating grooves.

Both ends of the inner surface of the sliding seat are provided with third rotating grooves. The inside of the third rotating grooves is rotationally connected with third rotating seats. Both ends of the inner surface of the third rotating seats are provided with fourth rotating grooves. The inside of the fourth rotating grooves is rotationally connected with fourth rotating seats.

[0006] Preferably, rubber pads are fixedly connected to the four corners of the inner surfaces of the second rotating seat and the fourth rotating seat.

[0007] Preferably, the sliding seat, the fixed seat, the first rotating seat, the second rotating seat, the third rotating seat, and the fourth rotating seat are all semi-circular structures.

[0008] Preferably, a threaded rod is rotatably connected to one end of the upper surface of the base, and the sliding seat is threadedly connected to the surface of the threaded rod.

[0009] Preferably, limiting rods are fixedly connected to both sides of one end of the upper surface of the base, and the sliding seat is slidably connected to the surface of the limiting rods.

[0010] Preferably, a limiting block is fixedly connected to one end of the threaded rod close to the fixed seat.

[0012] Compared with the prior art, the present utility model provides an axial positioning and anti-misalignment device for knuckle machining, having the following beneficial effects:

[0013] 1.

Through structures such as the first rotating seats 9, second rotating seats 11, third rotating seats 14 and fourth rotating seats 16, when axially positioning and clamping the knuckle, place the knuckle at the middle position of the upper end of the base 1. Rotate the threaded rod 2 by adjusting the handle 3 to make the sliding seat 7 slide towards the fixed seat 6. Clamp and fix the eight corners of the knuckle through the first rotating seats 9 and third rotating seats 14. The rotating seats can rotate freely inside the rotating grooves, realizing axial positioning and clamping of knuckles with different shapes. During the clamping process, further position and clamp the knuckle through the second rotating seats 11 and fourth rotating seats 16 at both ends of the first rotating seats 9 and third rotating seats 14 rotating inside the second rotating grooves 10 and fourth rotating grooves 15. This improves the flexibility and adaptability of the knuckle positioning and clamping, can effectively achieve precise fixation of knuckles with different shapes, ensures operation efficiency and safety. At the same time, through the cooperative action of multiple rotating seats, the clamping stability is enhanced, the error during the processing is reduced, and effectively avoids the problem that when processing different models of knuckles, it is necessary to replace the matching clamping blocks. This process not only consumes more time and labor, but also reduces the flexibility and efficiency of the production line and increases the production cost.

[0025] In the present utility model, preferably, rubber pads 12 are fixedly connected to the four corners of the inner surfaces of the second rotating seats 11 and fourth rotating seats 16. Through the provided rubber pads 12, when the rubber pads 12 come into contact with the surface of the knuckle, it realizes the protection of the surface of the knuckle during clamping, avoiding scratches or damages that may be caused by direct contact. At the same time, the buffering effect of the rubber pads 12 can absorb part of the vibration, improve the clamping stability and reliability, and ensure the accuracy and quality of the knuckle during processing or assembly.

[0026] In the present utility model, preferably, the sliding seat 7, the fixed seat 6, the first rotating seat 9, the second rotating seat 11, the third rotating seat 14 and the fourth rotating seat 16 are all semi - circular structures.

[0027] In the present utility model, preferably, one end of the upper surface of the base 1 is rotatably connected with a threaded rod 2, and the sliding seat 7 is threadedly connected to the surface of the threaded rod 2.

[0028] In the present utility model, preferably, both sides of one end of the upper surface of the base 1 are fixedly connected with limiting rods 4, and the sliding seat 7 is slidably connected to the surface of the limiting rods 4.

[0029] In the present utility model, preferably, one end of the threaded rod 2 close to the fixed seat 6 is fixedly connected with a limiting block 5. Through structures such as the limiting rods 4 and the limiting block 5 provided, the axial sliding of the sliding seat 7 is limited by the limiting rods 4, and the sliding distance of the sliding seat 7 is limited by the limiting block 5. The axial sliding and the sliding distance of the sliding seat 7 are effectively restricted, thereby ensuring the precise position control of the steering knuckle during the clamping process, avoiding the problem of inaccurate positioning caused by excessive sliding, improving the operation safety and clamping stability of the equipment, and at the same time simplifying the operation process and enhancing the work efficiency.

[0030] In the present utility model, preferably, one end of the threaded rod 2 away from the limiting block 5 is fixedly connected with an adjusting handle 3.

[0031] The working principle and usage process of the present utility model: When using the axial positioning and anti-misalignment device for steering knuckle machining of the present utility model, first place the steering knuckle at the middle position of the upper end of the base 1, then hold the adjusting handle 3 and slowly rotate the threaded rod 2, so that the sliding seat 7 slides along the threaded rod 2 towards the fixed seat 6. As the sliding seat 7 moves, the first rotating seat 9 and the third rotating seat 14 will gradually approach the eight corners on both sides of the steering knuckle and contact the surface of the steering knuckle through the rubber pads 12, realizing the preliminary clamping and fixing of the steering knuckle. Then, continue to rotate the adjusting handle 3, and the second rotating seat 11 and the fourth rotating seat 16 rotate in the second rotating groove 10 and the fourth rotating groove 15, further positioning and clamping the steering knuckle. When the sliding seat 7 reaches the position set by the limiting block 5, the axial sliding and the sliding distance of the sliding seat 7 are limited, ensuring the precise position control of the steering knuckle. Finally, after checking and confirming that the steering knuckle is firmly clamped, subsequent machining operations can be carried out. The whole process is simple and efficient, ensuring the accuracy and safety of steering knuckle machining.
