Description

Technical Field

[0001] The invention belongs to the technical field of ball stud processing, and in particular relates to an automatic processing device for a ball stud. Background Art

[0002] Ball pins are widely used in independent suspension systems. Control arms or thrust rods are often connected to other components through ball pins at the ends. The main function of the ball pins is to enable the wheels to bounce up and down and turn.

[0003] When drilling the rod of the ball stud, it is necessary to clamp and fix the ball head of the ball stud. The current clamping tooling used for the ball head of the ball stud has a problem that the contact surfaces between the clamping claw and the ball head are mostly flat. As a result, after clamping, the contact between the clamping claw and the ball head is in the form of point contact, and multiple points are in the same plane, resulting in poor clamping effect. The ball head is prone to shaking and slipping during clamping. Although a clamp for arc clamping of the ball head has appeared later, it cannot completely cover the ball head, and in order to ensure the stability of the clamping, a greater clamping force needs to be applied, which can easily cause wear of the ball head. Grinding in the later period can easily affect the overall dimensional accuracy of the ball stud. Summary of the invention

Then, the clamping hole 8 is squeezed and contracted by the extrusion of the external extrusion drive component, so as to better clamp the end of the ball stud.

[0026] Embodiment 4: This embodiment provides a ball stud automatic processing device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0027] The inner clamping parts include: A clamping block 9, the outer wall of which is cylindrical, and a clamping hole 8 is formed inside the clamping block; The outer clamping walls 10 are formed on both sides of the outer wall of the clamping block 9, and are inclined surfaces with decreasing diameters from the middle of the outer wall to both sides; A plurality of external positioning blocks 11 are evenly distributed in a circle at the middle of the outer wall of the clamping block 9, are integrally formed with the clamping block 9, and are formed with positioning holes coaxially arranged with and penetrating the clamping block 9; A plurality of clamping positioning posts 12 are respectively inserted into each positioning hole, slidingly matched with the positioning hole, and extending out of the positioning hole at both ends; A plurality of clamping support rods are respectively arranged in each positioning hole, and one end of the clamping support rods abuts against one side of the positioning hole, and the other end of the clamping support rods abuts against the clamping positioning column 12 in the positioning hole; A plurality of clamping deformation grooves 13 are evenly formed at both ends of the clamping block 9 according to the circumference, and extend from one end of the clamping block 9 to the other end, and the height is less than the height of the clamping block 9; The clamping deformation grooves 13 on both sides of the clamping block 9 are alternately distributed, and the external positioning block 11 is formed between two adjacent clamping deformation grooves 13; and under the action of the external extrusion drive member, the clamping block 9 shrinks as a whole, and at the same time, the gap between the clamping deformation grooves 13 becomes smaller, the accommodating space of the clamping hole 8 is reduced, and the external positioning block 11 moves toward the middle of the driving hole 7, prompting the clamping support rod to be compressed.

In order to further improve the sealing effect, an O-ring can be set on the side of the first support block 26b and the second support sheet 27a close to the side wall of the floating groove 30.
