[0018] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0019] As shown in Figures 1-4, a ball pin seat spherical grinding device includes a casing 10, which is characterized in that: two turntables are rotatably connected in the casing 10, a grinding rod 11 is installed in the turntable, a grinding ball 13 is fixed at one end of the grinding rod 11, and arc surface grinding can be performed by the grinding ball 13, an adjustment component is installed on the grinding rod 11, the adjustment component is located between the two turntables, the adjustment component includes an adjustment rod 15 and a connecting plate 14, the adjustment rod 15 is sleeved on the outer peripheral side of the grinding rod 11, the two turntables are connected together through the connecting plate 14, an adjusting nut 16 is rotatably connected on the connecting plate 14, the adjusting rod 15 is threadedly connected to the adjusting nut 16, and an arc-shaped notch is opened on the outer peripheral side of the casing 10, and the notch is located at the adjusting rod 15.

[0020] The turntable includes a secondary rotating block 12 and a main rotating block 17. A secondary sliding cavity 23 is provided in the secondary rotating block 12. The main rotating block 17 is installed in the casing 10 through a rotating shaft 18. A main sliding cavity 22 and a rotating cavity 21 are provided in the main rotating block 17. The main sliding cavity 22 is the same as the secondary sliding cavity 23. Both the secondary sliding cavity 23 and the main sliding cavity 22 are set as straight slots. The width of the straight slot is the same as the diameter of the grinding rod 11. The grinding rod 11 slides in the main sliding cavity 22 and the secondary sliding cavity 23 at the same time. A motor is provided in the casing 10. A motor output shaft 20 is installed on the motor. A rotating pin 19 is fixed to one side end face of the motor output shaft 20. The rotating pin 19 is located in the rotating cavity 21.

[0021] When in use, start the motor to drive the motor output shaft 20 to rotate. The rotation of the motor output shaft 20 drives the rotating pin 19 to rotate, thereby driving the main rotating block 17 to swing around the rotating shaft 18 under the restriction of the rotating chamber 21. Since the auxiliary rotating block 12 is connected to the main rotating block 17 through the connecting plate 14, the swing of the main rotating block 17 will also drive the auxiliary rotating block 12 to swing synchronously, and then the grinding rod 11 and the grinding ball 13 can be driven to swing at high frequency. The swing trajectory of the grinding ball 13 is an arc, and it can be used to grind the inner hole surface of the ball pin seat. The arc swinging grinding can make it adapt to the spherical surface of the inner hole, avoiding the phenomenon of bumps during grinding. At the same time, the swinging grinding can also avoid harm to the human body.

[0022] When a smaller arc radius is required, it is necessary to use a tool to screw the adjusting nut 16 from the notch of the housing 10. At this time, the adjusting rod 15 will drive the grinding rod 11 to slide in the main sliding cavity 22 and the auxiliary sliding cavity 23, so as to adjust the position of the grinding ball 13, so that the grinding arc can be adjusted as needed, which greatly increases its versatility.

[0023] Obviously, the described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
