Description

Technical Field

[0001] This utility model relates to the field of ball joint pin processing technology, and in particular to a tooling for synchronous grinding of ball joint pins and sockets in automobiles. Background Technology

[0002] The automotive ball joint pin synchronous grinding fixture is a high-efficiency, precision specialized equipment primarily used for the synchronous grinding of ball joint pins and sockets in automotive suspension systems to ensure their fit accuracy and surface quality. This fixture employs advanced CNC technology and a high-precision grinding head, enabling synchronous rotation and grinding of the ball joint and socket, effectively reducing machining errors and improving production efficiency. Its compact and rational structural design provides excellent rigidity and stability, making it suitable for mass production environments. Precise positioning and clamping devices ensure that the workpiece does not shift or vibrate during processing, thus guaranteeing machining accuracy and consistency. Furthermore, the fixture is equipped with automatic detection and compensation functions, enabling real-time monitoring and adjustment of the grinding status, further enhancing product quality and machining reliability. This fixture is widely used in the automotive parts manufacturing industry and is a key piece of equipment for improving the performance and production efficiency of ball joint pin assemblies.

[0003] Chinese patent CN117620696A discloses a processing method and apparatus for automotive suspension ball joint pins. This patent includes milling and pressing the ball end and neck of the workpiece. The processing method first mills the ball end and neck of the workpiece using a cutting tool to eliminate sharp corners and tool marks on the workpiece surface, ensuring a smooth outer surface. Then, a pressing tool is used to press the ball end and neck of the workpiece to eliminate stress, significantly improving the surface roughness and microhardness of the workpiece, thus enhancing the mechanical properties of the part. The cold heading process improves the overall toughness of the product, solving the problems of cumbersome procedures, low processing efficiency, and the need for further improvement in fatigue strength and overall toughness of the ball joint pins produced by traditional methods.

[0004] In the existing technology, the ball head and the socket of the ball pin need to be clamped and ground separately during the machining and grinding process. This machining method has a complicated process flow, which greatly reduces the machining efficiency. Utility Model Content

[0026] The aforementioned fixture for synchronous grinding of automotive ball joint pins and sockets includes a bracket 8 on one side of the friction cover 6. The bracket 8 and mounting plate 9 are used to fix the device to the machine frame by screws 10. The mounting plate 9 is located on one side of the bracket 8, and screws 10 are arranged around the periphery of the mounting plate 9.

[0027] The aforementioned tooling for synchronous grinding of automotive ball joint pins and sockets further includes:

[0028] The drive assembly 2 includes a rotating shaft 13 mounted on one side of the ball head 4. The rotating shaft 13 is inserted into the bearing 12 for positioning and support. The bearing 12 is mounted on the surface of the rotating shaft 13, and a bearing seat 11 is fitted onto the surface of the bearing 12. The bearing 12 inside the bearing seat 11 is used for fixation and support. A rod is fixedly mounted around the periphery of the bearing seat 11, and a motor 14 is mounted on one side of the rod. The rotating shaft 13 is mounted on one side of the motor 14. The motor 14 controls the high-speed rotation of the ball head 4 at its output end via the rotating shaft 13, thereby achieving the grinding effect.

[0029] The aforementioned fixture for synchronous grinding of ball joint pins and sockets in automobiles includes a support rod 15 on one side of the bearing housing 11. The surface of the support rod 15 has slots 16. A base plate 17 is located on one side of the support rod 15. The base plate 17 and screws 18 are the fixing components of this device. Screws 18 are located on both sides of the base plate 17.

[0030] The aforementioned tooling for synchronous grinding of automotive ball joint pins and ball sockets includes a friction flange 7 that is a protruding structure and is adapted to be disposed inside the ball socket 5.

[0033] Working principle:

[0034] In the actual design process, this utility model addresses the following shortcomings in the prior art: "In the prior art, the ball head and the ball socket of the ball pin need to be clamped and ground separately during the grinding process. This processing method is relatively complicated, which greatly reduces the processing efficiency." Therefore, the drive component 2 and the contour grinding component 3 are specifically proposed.

[0035] Driver Component 2:

[0036] During use, the main function of this component is to clamp and fix the ball head pin 1. The shaft 13 is connected and fixed through the bearing 12, and then the bearing 12 is used to achieve mating installation inside the bearing housing 11. The motor 14 controls the rotation of the shaft 12, thereby making the ball head pin on the shaft 13 a rotating body, and the ball head pin is ground in conjunction with the grinding device.

[0038] This component achieves a deep grinding effect on the ball head 4 and the ball socket 5. The friction cover 6 is fitted onto the surface of the ball head 4, while the friction flange 7 is mated inside the ball socket 5. As the ball head pin rotates, the friction cover 6 and the friction flange 7, which are contoured to the surface of the ball head 4, achieve a synchronous grinding effect on the ball head 4 and the ball socket 5. The friction cover 6 is fixedly mounted on a specific fixture via the bracket 8 and the mounting plate 9 for positioning and clamping.
