[0030] The following is in conjunction with the appendix Figure 1 -Appendix Figure 8 The present invention will be described in further detail below.

[0031] This invention discloses a small, high-precision spherical grinding machine apparatus. (Refer to...) Figures 1 to 4The system includes a body 1, a fixing mechanism 2, a grinding mechanism 3, and a driving mechanism 4. The fixing mechanism 2 includes a fixing sleeve 20, a first motor 21, multiple first electric cylinders 22, and multiple clamping plates 23 for fixing the ball. The fixing sleeve 20 is rotatably installed in the body 1. The first motor 21 is fixedly connected to the body 1, and the output shaft of the first motor 21 is fixedly connected to the fixing sleeve 20. The multiple first electric cylinders 22 are all fixedly connected to the inner wall of the fixing sleeve 20. The multiple clamping plates 23 are correspondingly arranged with the first electric cylinders 22 and connected to the extended ends of the first electric cylinders 22. The grinding mechanism 3 includes a second electric cylinder 31 and a grinding frame 32. The second electric cylinder 31 is fixedly connected to the body 1, and the grinding frame 32 is fixedly connected to the extended end of the second electric cylinder 31. Grinding discs that contact the ball are installed on the grinding frame 32. The multiple clamping plates 23 are... Each component is equipped with a mounting plate 24, on which multiple mounting plates 24 are rolled balls 25 that contact the ball. The drive mechanism 4 includes a drive seat 40 mounted on the mounting plate 24 and a drive wheel 41 rotatably mounted in the drive seat 40. The drive wheel 41 contacts the ball. The drive mechanism 4 also includes a drive component for driving the drive wheel 41 to rotate. When the ball needs to be polished, the ball is first placed between multiple clamping plates 23 and fixed with the clamping plates 23. At the same time, the balls 25 contact the ball. Then, the polishing mechanism 3 is started to polish the ball. When one side of the ball is polished, the drive component is started. The drive component drives the drive wheel 41 to rotate. The drive wheel 41 drives the ball to rotate. The balls 25 guide the ball so that the unpolished side of the ball contacts the polishing mechanism 3 and is polished, thus solving the problem of low efficiency in ball polishing.

[0032] An anti-slip pad is fixedly connected to the contact surface between the clamp 23 and the ball, which increases the friction between the clamp 23 and the ball.

[0033] Reference Figures 2 to 4 The mounting plate 24 and the clamping plate 23 are slidably connected. The extended end of the first electric cylinder 22 is fixedly connected to the mounting plate 24. A moving part for driving the clamping plate 23 to move is installed on the fixed sleeve 20. When one side of the ball is polished, the moving part is activated. The moving part drives the clamping plate 23 to move away from the ball, so that the clamping plate 23 is separated from the ball. During the rotation of the ball, the friction between the ball and the clamping plate 23 is reduced, and damage to the ball is avoided.

[0034] Reference Figure 3 and Figure 4Two clamping plates 23, two mounting plates 24, and two drive wheels 41 are each provided. The two mounting plates 24 and the two drive wheels 41 are arranged in a staggered manner. Multiple balls 25 are arranged along the length of the mounting plate 24 and are arranged symmetrically along the radial direction of the ball. The mounting plate 24 has a storage groove, and the drive seat 40 is slidably installed in the storage groove. The drive mechanism 4 also includes a sliding member for driving the drive seat 40 to move. Through the staggered drive wheels 41, the ball can be driven to rotate from the vertical and longitudinal directions respectively, so that the ball can be fully polished without the need for workers to remove the ball and reinstall it, further solving the problem of low ball surface polishing efficiency. When the sliding member is activated, the sliding member drives the drive seat 40 to move, and the drive seat 40 drives the drive wheels 41 to move, so that the drive wheels 41 are separated from the ball, avoiding the drive wheels 41 from affecting the ball polishing process.

[0035] Reference Figures 3 to 5 The sliding component includes a second motor 42 fixedly connected to the fixed sleeve 20. A first telescopic shaft 43 is fixedly connected to the output shaft of the second motor 42. The end of the first telescopic shaft 43 away from the second motor 42 is rotatably connected to the mounting plate 24. A sliding screw 44 fixedly connected to the first telescopic shaft 43 is rotatably installed in the storage groove. The sliding screw 44 is threadedly connected to the drive seat 40. When the second motor 42 is started, the second motor 42 drives the first telescopic shaft 43 to rotate. The first telescopic shaft 43 drives the sliding screw 44 to rotate. The sliding screw 44 drives the drive seat 40 to move. The drive seat 40 drives the drive wheel 41 to move. When one side of the ball is polished, the drive wheel 41 contacts the ball, and the ball can be polished.

[0036] Reference Figures 4 to 7 A telescopic rod 45 is fixedly connected to the drive seat 40. The telescopic rod 45 is threadedly connected to the sliding screw 44. A first spring 46 is provided in the telescopic rod 45. When it is necessary to grind balls of different diameters, the first spring 46 provides a push to the telescopic rod 45, so that the drive wheel 41 is in close contact with the ball, thereby driving the ball to rotate.

[0037] Reference Figures 5 to 7The driving component includes a second telescopic shaft 47 rotatably mounted between the inner wall of the storage slot and the drive seat 40. One end of the second telescopic shaft 47 is connected to the sliding screw 44 via a conveyor belt, and the other end of the second telescopic shaft 47 is connected to the shaft in the drive wheel 41 via a bevel gear set. A second spring 48 is fixedly connected between the drive seat 40 and the inner wall of the storage slot. During the rotation of the sliding screw 44, the sliding screw 44 drives the second telescopic shaft 47 to rotate, and the second telescopic shaft 47 drives the drive wheel 41 to rotate, thereby driving the ball to rotate. When the telescopic rod 45 moves to the bottom of the sliding screw 44, the telescopic rod 45 stops moving, while the sliding screw 44 continues to drive the second telescopic shaft 47 to rotate.

[0038] Reference Figures 2 to 5 The moving parts include a movable screw 26 rotatably mounted on the mounting plate 24, which is threadedly connected to the clamping plate 23. A third telescopic shaft 27 is rotatably mounted between the fixed sleeve 20 and the mounting plate 24, and is fixedly connected to the movable screw 26. A connecting ring 28 is rotatably mounted on the fixed sleeve 20, and two arc-shaped racks 281 are fixedly connected to the connecting ring 28. The two third telescopic shafts 27 are respectively fixedly connected to a first gear 271 that meshes with the arc-shaped racks 281. Two sets of gears are mounted on the fixed sleeve 20 that are respectively connected to the second motor 42. With corresponding transmission components, both second motors 42 can drive the connecting ring 28 to rotate through the transmission components. When it is necessary to rotate the ball longitudinally or vertically, the second motors 42 are started respectively. The second motors 42 drive the connecting ring 28 to rotate through the transmission components. The connecting ring 28 drives the arc-shaped rack 281 to move. The arc-shaped rack 281 drives the first gear 271 to rotate. The first gear 271 drives the third telescopic shaft 27 to rotate. The third telescopic shaft 27 drives the moving screw 26 to rotate. The moving screw 26 drives the clamping plate 23 to separate from the ball.

[0039] Reference Figures 2 to 8 A third spring 29 is fixedly connected between the connecting ring 28 and the fixed sleeve 20. The transmission component includes an arc-shaped toothed plate 282 fixedly connected to the connecting ring 28 and multiple teeth 283 hinged to the arc-shaped toothed plate 282. The hinge shaft installed in the teeth 283 is located on one side of the teeth 283. A torsion spring is sleeved on the hinge shaft installed in the teeth 283. A second gear 421 that meshes with the multiple teeth 283 is fixedly connected to the output shaft of the second motor 42. When one of the second motors 42 drives the second gear 421 to rotate, the second gear 421 drives the teeth 283 to move. The teeth 283 drive the arc-shaped toothed plate 282 to move. The arc-shaped toothed plate 282 drives the connecting ring 28 to move, thereby causing the clamping plates 23 on both sides of the sphere to move away from each other at the same time.

[0040] Reference Figure 5 and Figure 6 A cleaning mechanism 5 is installed on the clamping plate 23. The cleaning mechanism 5 includes a cleaning roller 51 that contacts the spherical surface. A cloth is fitted on the cleaning roller 51. An installation groove is opened on the side wall of the clamping plate 23 facing the spherical body. A moving screw 26 extends into the installation groove. A cleaning screw 52 is fixedly connected to the moving screw 26. A cleaning plate 53 that is slidably installed in the installation groove is threaded onto the cleaning screw 52. The cleaning roller 51 is rotatably installed at the bottom of the cleaning plate 53. As the clamping plate 23 moves away from the spherical body, the moving screw 26 drives the cleaning screw 52 to rotate. The cleaning screw 52 drives the cleaning plate 53 to move. The cleaning plate 53 drives the cleaning roller 51 to contact the spherical body. The cleaning roller 51 can pick up the grinding debris on the spherical body and prevent the debris from entering between the drive wheel 41 and the spherical body.

[0041] The implementation principle of the small high-precision spherical grinding machine device in this embodiment of the invention is as follows: When grinding a sphere, the sphere is first placed between multiple clamping plates 23, and the first electric cylinder 22 is activated. The first electric cylinder 22 drives the mounting plate 24 to move, and the mounting plate 24 drives the clamping plates 23 to move, thereby fixing the sphere. At the same time, the ball bearings 25 contact the sphere. Then, the second electric cylinder 31 and the grinding frame 32 are activated, so that the grinding disc grinds the sphere. When one side of the sphere is ground, the second motor 42 is activated. The second motor 42 drives the first telescopic shaft 43 to rotate, and the first telescopic shaft 43 drives the sliding screw 44 to rotate. The sliding screw 44 drives the telescopic rod 45 to move, and the telescopic rod 45 drives the drive seat 40 to move. The drive seat 40 drives the drive wheel 41 to contact the ball, while the sliding screw 44 drives the second telescopic shaft 47 to rotate. The second telescopic shaft 47 drives the drive wheel 41 to rotate, thereby driving the ball to rotate. The second motor 42 drives the second gear 421 to rotate, the second gear 421 drives the teeth 283 to move, the teeth 283 drives the arc-shaped toothed plate 282 to move, the arc-shaped toothed plate 282 drives the connecting ring 28 to rotate, the connecting ring 28 drives the arc-shaped rack 281 to move, the arc-shaped rack 281 drives the first gear 271 to rotate, the first gear 271 drives the third telescopic shaft 27 to rotate, the third telescopic shaft 27 drives the moving screw 26 to rotate, and the moving screw 26 drives the clamping plate 23 to separate from the ball.
