Description

Technical Field

[0001] This utility model relates to the field of steering knuckle technology, specifically a steering knuckle ball pin press-fitting device. Background Technology

[0002] Currently, the press-fitting of steering knuckle ball pins utilizes servo press equipment and specialized press-fitting fixtures. The ball pins are pressed into the steering knuckle ball pin mounting holes according to customer drawings. The suitability of the press-fitting fixture directly affects the efficiency of the press-fitting process and the product qualification rate. Existing press-fitting fixtures lack precise guiding functions for the lower die during ball pin press-fitting, requiring operators to visually adjust the tooling during the process. Uneven force distribution due to ball pin misalignment can lead to unqualified press-fitting.

[0003] The utility model patent with authorization announcement number CN 217254212 U discloses a steering knuckle ball pin press-fitting fixture, relating to the field of steering knuckles. It includes an upper press-fitting die, a ball pin, a steering knuckle, a lower press-fitting die, and a base plate. The steering knuckle has a first connecting arm and a second connecting arm. The first connecting arm has a ball pin press-fitting hole, with a central hole penetrating the center of the ball pin. The lower press-fitting die is supported on the base plate, and its upper surface has a boss. A pin is coaxially positioned at the center of the lower press-fitting die, with its top extending from the upper surface to insert into the central hole of the ball pin for positioning and guidance. The upper press-fitting die is fitted onto the top of the ball pin, and the upper press-fitting die applies pressure to the ball pin using a press. This utility model is suitable for the press-fitting assembly of steering knuckle ball pins. The positioning fixture has a simple structure, is easy to manufacture, and has low cost. Because the ball pin is accurately guided, the press-fitting accuracy is high. During press-fitting, the ball pin is subjected to uniform force without damage. The press-fitting assembly position is limited and guaranteed by the press-fitting fixture, ensuring no deviation.

[0004] The above-disclosed structure uses a simple guide structure for press-fitting production, but it lacks a combined pressure plate and guide post to connect the tensioning plate, and cannot be assembled by connecting ball pins, which affects the accuracy and stability of the guide alignment and has poor adaptability, and needs to be improved. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a steering knuckle ball pin press-fitting device to solve the problem that existing press-fitting devices lack guide columns for installing tension plates to assist in positioning.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a steering knuckle ball pin press-fitting device, comprising a fixing plate, a mounting bracket fixedly connected to the upper surface of the fixing plate, a telescopic rod fixedly mounted on the upper surface of the mounting bracket, a threaded cylinder threadedly connected to the head of the telescopic rod, a pressure plate fixedly connected to the lower end of the threaded cylinder, a guide post fixedly connected to the lower surface of the pressure plate, a mounting groove provided at the lower end of the guide post, an air pipe provided in the middle of the mounting groove, a square connecting groove provided on the side of the air pipe, air holes provided on the surface of the air pipe, a through groove provided on one side of the square connecting groove, the through grooves being evenly distributed on the outer surface of the guide post, a tensioning plate slidably mounted inside the through groove, a partition plate fixedly connected to one end of the tensioning plate, the partition plate slidably mounted inside the square connecting groove, return springs fixedly connected to both ends of the partition plate, a sealing ring fixedly connected to the outer surface of the partition plate, and the sealing ring slidably connected to the inner surface of the square connecting groove.

[0009] Preferably, the pressure plate has a transverse hole inside, one end of which is threaded with a hose, and the other end of which is connected to one end of an air pipe. A baffle is connected through a mounting groove, and a positioning device can be assembled and installed to limit and support the internal partition, preventing loosening and leakage, ensuring safety and stability. Furthermore, the hose connected through the transverse hole allows gas to be introduced for pneumatic control, which is efficient, stable, and easy to use.

[0010] Preferably, the surface of the fixing plate is provided with clearance holes, which are aligned with the lower end of the guide post.

[0011] Preferably, threaded rods are threaded on both sides of the mounting bracket, and a clamping plate is rotatably connected to one end of each threaded rod.

[0012] Preferably, the clamping plate is slidably mounted on the upper surface of the fixed plate and located on both sides of the clearance hole. By setting the clearance hole on the fixed plate and combining it with the threaded rod and clamping plate connected by the mounting bracket, the steering knuckle can be assisted in positioning, which is convenient for downward pressing and positioning, and is conducive to production and use, and is efficient and stable.

[0013] Compared with the prior art, this utility model provides a steering knuckle ball pin press-fitting device, which has the following beneficial effects: Through its design, the press-fitting device connects to the telescopic rod via a mounting bracket on the fixed plate, thereby installing the pressure plate and guide column. This facilitates vertical adjustment for press-fitting production. Simultaneously, the tensioning plate and partition are installed via a through groove, allowing for telescopic adjustment to tension the positioning ball pin. This ensures accurate alignment after stable connection, guaranteeing the stability and convenience of press-fitting. It is stable, efficient, and beneficial for production use.

The partition 22 and the tensioning plate 21 can be installed separately into multiple square connecting grooves 18, which is convenient for installation and use. During press-fitting, the ball pin can be put on the surface of the guide column 15. Then, compressed air is introduced into the air pipe 17 to push the partition 22 to move. The tensioning plate 21 extends outward from the through groove 2 and can be pressed against the inner wall of the ball pin, which is convenient for tensioning and positioning, adaptable to different inner diameters, and convenient for combination positioning. Then, the telescopic rod 12 is extended to push the pressure plate 14 and the guide column 15 to move downward, thereby aligning with the installation position of the steering knuckle.

A hose 28 is threadedly installed at one end of the transverse hole 27, and the other end of the transverse hole 27 is connected to one end of the air tube 17. The baffle is connected through the mounting groove, allowing for combined installation and positioning, thereby limiting and supporting the internal partition, preventing loosening and leakage, ensuring safety and stability. The hose is connected through the transverse hole. It can be pneumatically controlled by gas, which is efficient, stable and easy to use. The hose 28 is connected to the air valve and the air source to control the air intake. Then, compressed gas can be introduced into the transverse hole 27 and the air pipe 17, and then into the square connecting groove 18 through the air hole 19. The compressed gas can push the partition 22, thereby pushing the tension plate 21 to slide. It can be extended and retracted, which is convenient for adjustment. When the air source is disconnected, the partition 22 can be moved by the return spring 23, thereby resetting and retracting the tension plate 21, which is convenient for loosening the ball pin.
