DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0029] See also Figures 1-4 The present application provides a steel ball surface grinding and polishing device, comprising a bracket 10, a rotating member 20 being provided at the upper end of the bracket 10, a grinding member 30 being eccentrically provided on the rotating member 20, and a support platform 40 being provided at the lower end of the bracket 10. The support platform 40 comprises three rollers 41 arranged in a triangle, each of which rotates independently, and a ball 50 being placed on the rollers 41. The rotating member 20 is used to rotate the eccentric grinding member 30 around the ball 50 for grinding, thereby achieving a wider and more uniform grinding range. The support platform 40 composed of three rollers 41 is used to drive the ball 50 to rotate in any direction, thereby avoiding dependence on manual labor during grinding and improving automation.

[0030] See also Figures 1-4The support platform 40 also includes a base 42, with rollers 41 rotatably connected to the base 42. Each roller 41 is connected to a motor A43 corresponding to its axis. The three motors A43 are servo-controlled and can drive the steel balls to rotate in any direction, thus avoiding the need to manually change the grinding direction and improving automation.

[0031] See also Figures 1-4 The bracket 10 is provided with a nozzle 60 toward the sphere 50. The nozzle 60 can spray the grinding fluid toward the sphere 50 to help polishing. In this embodiment, the nozzle 60 adopts a gooseneck tube, and the direction of the spraying can be freely adjusted.

[0032] See also Figures 1-4 , a container 70 is provided at the lower end of the bracket 10. The container 70 is used to collect the flowing grinding liquid to avoid polluting the environment.

[0033] See also Figures 1-4 The rotating member 20 includes a rotating frame 21 and a motor B22. The rotating frame 21 is rotatably connected to the upper end of the bracket 10, and the output end of the motor B22 is connected to the axis of the rotating frame 21. The rotating member 20 also includes a worm gear 23 and a worm 24. The worm gear 23 is fixedly connected to the rotating frame 21, and the worm 24 is fixedly connected to the output end of the motor B22. The worm 24 meshes with the worm gear 23. The motor B22 drives the worm 24 to rotate, which in turn drives the worm gear 23 and the rotating frame 21 to rotate, causing the grinding member 30 to rotate around the sphere 50 and grind, which helps to improve the uniformity of the grinding.

[0034] See also Figures 1-4 The grinding member 30 includes a sleeve 31 and an inner rod 32. The sleeve 31 is fixedly connected to the rotating frame 21, and the inner rod 32 is slidably connected to the sleeve 31. A spring 33 is provided in the sleeve 31 to press against the inner rod 32. The lower end of the inner rod 32 is fixedly connected to a grinding head 34. The grinding member 30 also includes a motor C35, a main gear 36, and a slave gear 37. The motor C35 is mounted on the rotating frame 21. The main gear 36 is fixedly connected to the output end of the motor C35. The slave gear 37 is rotationally connected to the rotating frame 21. The slave gear 37 is axially slidably connected to the inner rod 32. The main gear 36 and the slave gear 37 are meshed. The spring 33 pushes the inner rod 32 to press the grinding head 34 against the sphere 50. The motor C35 drives the inner rod 32 to rotate through the engagement of the main gear 36 and the slave gear 37, and then drives the grinding head 34 to rotate. When the grinding head 34 is pushed back, the sphere 50 can be put in or taken out, and the sliding groove on the inner rod 32 is engaged with the circumferential direction of the slave gear 37 to achieve the effect of circumferential fixation and axial sliding.

[0035] The working principle of the steel ball surface grinding and polishing equipment is as follows: push the grinding head 34 back and put the ball 50 between the three rollers 41. After releasing the hand, the spring 33 pushes the inner rod 32 to press the grinding head 34 against the ball 50. The motor C35 drives the inner rod 32 to rotate through the engagement of the main gear 36 and the slave gear 37, thereby driving the grinding head 34 to rotate. At the same time, the motor B22 drives the worm 24 to rotate, thereby driving the worm wheel 23 and the rotating frame 21 to rotate, and drives the grinding piece 30 to rotate around the ball 50 for grinding, thereby improving the grinding effect. The uniformity of grinding is improved. At the same time, the three motors A43 are servo-controlled and can drive the steel ball to rotate in any direction, further improving the uniformity of grinding, thereby avoiding the situation of manually changing the grinding direction. In summary, the rotating part 20 is used to carry the eccentric grinding part 30 to rotate around the sphere 50 for grinding, and the grinding range is larger and more uniform. The support platform 40 composed of three rollers 41 is used to drive the sphere 50 to rotate in any direction, thereby avoiding dependence on manual labor during grinding and improving automation.
