Technical Field
[0001] The invention relates to the technical field of grinding processing, in particular to a grinding processing device for a ball pin seat of an automobile chassis. 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 pin is to achieve the up and down bouncing and steering movement of the wheel. There are two main types of ball pin structures: one is a combination of a spherical pin and an integral ball seat, and the other is a combination of a hemispherical ball pin and a spherical component. In the past, spiral springs were mostly used for preloading and compensating wear. Now, synthetic resin ball seats with elasticity and lubrication are widely used, which not only reduces costs but also improves handling stability. The ball pin is mainly composed of an end cap, a ball pin, a ball seat and a dust cover.
[0003] During the processing of the ball stud, the ball head needs to be polished to make it smooth to avoid friction during use and hinder rotation. Due to the special structure and various specifications of the ball head of the ball stud, it is difficult to polish. During polishing, there is no special clamping tool, and the ball stud often deviates during the polishing process, resulting in excessive polishing, making the ball stud a defective product and unusable, wasting raw materials and increasing production costs.

The elastic ring 57 is deformed by force and moves upward along the fixing seat 52. Through the elastic ring 57, the ball 55 contacts the top of the ball pin seat, and the ball pin seat is fixed through the upper and lower cooperation of the ball 24 and the ball 55.
[0044] When the ball and pin seat is placed, extrusion is generated between the outer side of the ball head at the top of the ball and pin seat and the outer side of the abrasive belt 686, the rotating plate 683 is forced to rotate around the slider 681, and the connecting plate 684 is deformed by force, so that the abrasive belt 686 contacts the outer side of the ball head of the ball and pin seat of different specifications, so that the abrasive belt 686 remains in a tensioned state and always fits the surface of the spherical workpiece.
[0045] After the ball pin seat is fixed, the elastic performance of the spring plate 64 is used to make the rotating cylinder 67 contact the outer side of the ball pin seat. The ball pin seat is limited by symmetrically setting square plates 65 at the opening of the fixed ring 62. The motor 66 is connected to an external power supply to drive the rotating cylinder 67 to rotate. The friction between the rotating cylinder 67 and the ball pin seat drives the ball pin seat to rotate.
[0046] During grinding, the coolant inside the liquid storage tank 7 is sprayed out through the liquid outlet pipe 9 to cool the grinding area to avoid local overheating of the grinding area, which affects the service life of the grinding parts and the quality of the products. The coolant flows downward along the ball pin seat, falls into the liquid accumulation bucket 22, and returns to the inside of the liquid storage tank 7 from the inside of the cylinder 21 and the connecting pipe 8.
[0047] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
