A bevel gear is fixedly connected to one end of the rotating shaft. A bevel gear is meshed with the bevel gear. A rotating rod is fixedly connected to the bottom of the bevel gear. An arc-shaped plate is fixedly connected to the bottom end of the rotating rod.

[0006] There are two arc-shaped plates, one of which has a low-precision frosted plate and the other has a high-precision frosted plate. A box is set on the top of the housing, and a fixed column is fixedly connected inside the box. A bidirectional screw is rotatably connected inside the box via a bearing. Two moving plates are threaded onto the bidirectional screw. The moving plates are slidably connected to the fixed column. Two connecting blocks are fixedly connected to the top of the moving plates, and clamping plates are fixedly connected to the top of the two connecting blocks. A hemispherical body is set on the top of the box, and a rectangular groove is opened at the bottom of the hemispherical body corresponding to the position of the clamping plate.

[0010] As a further embodiment of this utility model: a fixed rod is fixedly connected inside the box, and a screw rod is rotatably connected inside the box via a bearing. Two movable plates are threadedly connected to the screw rod, and the movable plates are slidably connected to the fixed rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This integrated grinding device for hemispherical production, by setting up low-precision grinding plates, high-precision grinding plates, square holes, square rods, driving gears, and driven gears, allows the hemispherical body to be placed on two clamping plates, with the clamping plates positioned inside rectangular slots. The bidirectional screw is then rotated; because the threads on both sides of the bidirectional screw are in opposite directions, its rotation causes the two moving plates and the two clamping plates to move closer together, clamping and fixing the hemispherical body. At this point, an electric push rod is activated to push the housing and the arc-shaped plate downwards, causing the arc-shaped plate to enclose the hemispherical body. The motor then drives the driving gear, driven gear, and arc-shaped plate to rotate, causing the arc-shaped plate to pass through a low-precision grinding groove. The low-precision grinding plate polishes the hemispherical body. When it is necessary to switch from a low-precision grinding plate to a high-precision grinding plate, turning the knob drives the screw to rotate, causing the moving plate, sliding plate, rotating shaft, and arc plate to move. This allows the square rod to be inserted into the interior of another square hole. Due to the square design of the square rod and square hole, when the rotating column rotates, it can drive the other rotating shaft and arc plate to rotate through the square rod, thus completing the work of switching from a low-precision grinding plate to a high-precision grinding plate. This device can directly switch from a low-precision grinding plate to a high-precision grinding plate without spending a lot of time changing grinding plates, improving work efficiency and demonstrating good integration.

[0015] 2. This integrated grinding device for hemispherical production, by setting up a bidirectional screw, moving plates, and clamping plates, allows the hemispherical body to be placed on the two clamping plates during use, with the clamping plates located inside rectangular grooves. Rotating the bidirectional screw causes the two moving plates and clamping plates to move closer together, clamping and fixing the hemispherical body. This clamping and fixing effectively prevents displacement of the hemispherical body during grinding, thus improving grinding accuracy. Attached Figure Description

[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0023] like Figure 1-5 As shown, this utility model provides a technical solution: an integrated grinding device for hemispherical production, including a housing 1, four columns 2 fixedly connected to the top of the housing 1, a top plate 3 fixedly connected to the top of the four columns 2, an electric push rod 4 fixedly connected to the top of the top plate 3, a U-shaped plate 5 fixedly connected to the telescopic end of the electric push rod 4 through the top plate 3, a housing 7 fixedly connected to the bottom of the U-shaped plate 5, a support plate 9 fixedly connected to one side of the housing 7, a motor 11 fixedly connected to the top of the support plate 9, a transmission shaft 20 fixedly connected to the output end of the motor 11, a drive gear 21 fixedly connected to one end of the transmission shaft 20, a driven gear 22 meshing with the bottom of the drive gear 21, the transmission shaft 20 being rotatably connected to the U-shaped plate 5 via bearings, a rotating rod 29 being rotatably connected to a sliding plate 17 via bearings, and two triangular plates 10 fixedly connected to one side of the housing 7. Because of the triangular plates 10, they can support the support plate 9 and the motor 11, thereby improving the stability of the motor 11 and the support plate 9. The triangular plates 10 are fixedly connected to the bottom of the support plate 9.

[0024] Both sides of the driven gear 22 are fixedly connected to rotating columns 23. One end of the rotating column 23 is fixedly connected to a square rod 24. Due to the square design of the square rod 24 and the square hole 26, when the square rod 24 is inserted into the square hole 26, the rotating column 23 can drive the rotating shaft 25 and the arc plate 30 to rotate through the square rod 24, ensuring the normal operation of subsequent work. A screw 14 is rotatably connected to one side of the housing 7 through a bearing. A movable plate 16 is threadedly connected to the screw 14. A sliding plate 17 is fixedly connected to the bottom of plate 16. Two connecting plates 12 are fixedly connected to the top of sliding plate 17. A rotating shaft 25 is rotatably connected to the connecting plate 12 via bearings. A square hole 26 corresponding to the shape of the square rod 24 is opened on the rotating shaft 25. A bevel gear 27 is fixedly connected to one end of the rotating shaft 25. A bevel gear 28 meshes with bevel gear 27. A rotating rod 29 is fixedly connected to the bottom of bevel gear 28. Two fixed plates 13 are fixedly connected to the top of the inner wall of the housing 7. A rotating column 23 is rotatably connected to the fixed plate 13 via bearings.

[0025] An arc-shaped plate 30 is fixedly connected to the bottom end of the rotating rod 29. There are two arc-shaped plates 30. One arc-shaped plate 30 is equipped with a low-precision frosted plate 31, and the other arc-shaped plate 30 is equipped with a high-precision frosted plate 32. A box 8 is set on the top of the housing 1. A fixed column 36 is fixedly connected inside the box 8. A double-acting screw 35 is rotatably connected inside the box 8 through a bearing. Two moving plates 39 are threadedly connected to the double-acting screw 35. Slide rails 18 are fixedly connected to the front and back of the sliding plate 17. The housing 7 has openings corresponding to the positions of the slide rails 18. The slide 19 has a slide bar 18 and a slide 19. When the sliding plate 17 moves, the slide bar 18 will slide inside the slide 19. The slide 19 can support and limit the slide bar 18 and the sliding plate 17, thereby improving the stability and accuracy of the movement of the sliding plate 17. The slide bar 18 is slidably connected inside the slide 19. A fixed rod 41 is fixedly connected inside the housing 1. A screw 40 is rotatably connected inside the housing 1 through a bearing. Two movable plates 42 are threadedly connected to the screw 40. The movable plates 42 are slidably connected to the fixed rod 41.

[0026] The moving plate 39 is slidably connected to the fixed column 36. Two connecting blocks 37 are fixedly connected to the top of the moving plate 39. A clamping plate 38 is fixedly connected to the top of the two connecting blocks 37. A hemispherical body 33 is set on the top of the box body 8. A rectangular groove 34 is opened at the bottom of the hemispherical body 33 corresponding to the position of the clamping plate 38. Two connecting pieces 43 are fixedly connected to the top of the moving plate 42. There are four connecting pieces 43. The box body 8 is fixedly connected to the top of the four connecting pieces 43. A knob 44 is fixedly connected to one end of the screw 40. Two T-shaped rods 6 are fixedly connected to the top of the U-shaped plate 5. Because of the T-shaped rods 6, when the shell 7 moves, the T-shaped rods 6 will slide on the top plate 3. The T-shaped rods 6 can play the role of limiting and guiding the shell 7, improving the stability and accuracy of the movement of the shell 7. The T-shaped rods 6 are slidably connected to the top plate 3. A knob 15 is fixedly connected to one end of the screw 14.

[0027] The working principle of this utility model is as follows:

[0028] In use, the hemispherical body 33 is placed on the two clamping plates 38, so that the clamping plates 38 are located inside the rectangular groove 34. At this time, the bidirectional screw 35 is rotated. Since the threads on both sides of the bidirectional screw 35 are in opposite directions, when the bidirectional screw 35 rotates, it will cause the two moving plates 39 and the two clamping plates 38 to move closer together, thereby clamping and fixing the hemispherical body 33. At this time, the electric push rod 4 is activated to push the housing 7 and the arc plate 30 downward, so that the arc plate 30 covers the hemispherical body 33. At this time, the motor 11 is activated to drive the driving gear 21, the driven gear 22 and the arc plate 30 to rotate. The arc plate 30 will polish the hemispherical body 33 through the low-precision grinding plate 31. When it is necessary to switch the low-precision grinding plate 31 to the high-precision grinding plate 32, turn the knob. The screw 14 rotates, causing the movable plate 16, sliding plate 17, rotating shaft 25, and arc plate 30 to move. This allows the square rod 24 to be inserted into the other square hole 26. Due to the square design of the square rod 24 and the square hole 26, when the rotating column 23 rotates, it can drive the other rotating shaft 25 and arc plate 30 to rotate through the square rod 24, thus completing the work of switching the low-precision grinding plate 31 to the high-precision grinding plate 32. At this time, rotating the knob 44 drives the screw 40 to rotate, causing the movable plate 42 to move the box 8 and the hemispherical body 33, so that the hemispherical body 33 is located directly below the other arc plate 30. At this time, the hemispherical body 33 can be polished by the high-precision grinding plate 32.
