Problems solved by technology

The main technical problems are: (1) the ball head size of the ball stud pin Tolerance is The existing processing technology is difficult to guarantee; (2) After the ball stud is riveted, the ejection force needs to be at least 1.5KN, and the torque needs to be at least 12Nm
After riveting with the bracket, the ejection force can be guaranteed, and the torque is always only between 5-7Nm, which cannot meet the process requirements

Embodiment

[0027] A ball stud bracket such as Figure 1-3 , the ball stud bracket includes a ball stud 1, a welding screw 2 and a bracket 3; the ball stud 1 is riveted to one end of the bracket 3, and the welding screw 2 is welded to the other end of the bracket 3. The bracket 3 is at a 90° angle. The bending part of the bracket 3 is provided with reinforcing ribs.

[0028] A riveting hole 31 for riveting the ball stud 1 is opened on the bracket 3 , and the riveting hole 31 is oval. The riveting hole is an oval hole. After riveting through the mold, part 1 of the ball stud enters into the straight part 3 of the bracket to achieve anti-rotation effect and greatly increase the torque. The size of the riveting hole 31 is

[0029] The preparation process of the ball stud 1 is as follows: firstly make a semi-finished product through cold heading; The dimensional tolerance problem of the ball stud was completely solved, the sample delivery was approved, and mass production went smoothly....

Abstract

The invention relates to a ball pin support and a machining method thereof. The ball pin support comprises a ball pin (1), a welding screw (2) and a support body (3). The ball pin (1) is riveted at one end of the support (3), and the welding screw (2) is welded at the other end of the support (3). The support (3) is provided with a riveting hole (31) used for riveting the ball pin (1), and the riveting hole (31) is oval. The preparation process of the ball pin (1) comprises the following steps: firstly, carrying out cold heading to prepare a semi-product; and performing finish turning through a numerical control lathe. The processing method comprises the following steps: firstly, welding the welding screw (2) and the bracket (3); and then the ball pin (1) and the support (3) are riveted through a riveting die, and machining of the ball pin support is completed. Compared with the prior art, the riveting device has the advantages of accurate ball head size, large torque after riveting and the like.

Description

technical field [0001] The invention relates to the field of ball stud parts, in particular to a ball stud bracket and a processing method thereof. Background technique [0002] There are two main structures of the ball stud: one is the combination of the ball pin and the integral ball seat, and the other is the combination of the hemispherical ball pin and the spherical member. In the past, helical springs were often used for preloading and wear compensation structures, but now synthetic resin ball seats with elasticity and lubrication are widely used, which not only reduces costs, but also improves handling stability. In addition, the material and shape of the dust cover, the type of grease, etc. have been greatly improved, and the grease nipple has been cancelled, realizing a maintenance-free structure. [0003] Ball stud brackets generally include ball studs, welding screws and brackets. The output of this product is generally about 40,535 pieces per year. The producti...
