[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Figure 1-4As shown, this utility model provides an end-face grinding device for ceramic grinding wheel processing, including a worktable 1, a moving unit 2, and a grinding unit 3. The moving unit 2 is mounted on the worktable 1, and the grinding unit 3 is mounted on the moving unit 2. The moving unit 2 can control the grinding unit 3 to move up and down and horizontally, thereby enabling the grinding unit 3 to perform comprehensive grinding processing on the end face of the ceramic grinding wheel. This is prior art disclosed in the prior art document and will not be described in detail here. The worktable 1 is provided with a clamping unit 4. By setting the clamping unit 4, the ceramic grinding wheel can be clamped and... The ceramic grinding wheel is flipped so that both end faces can be ground without disassembling it, thereby improving the convenience and efficiency of ceramic grinding. The clamping unit 4 includes a frame plate 41, and two frame plates 41 are provided. The two frame plates 41 are fixedly mounted symmetrically on the upper surface of the worktable 1. A rotating shaft 42 is rotatably mounted on one end of each frame plate 41. A fixing frame 43 is fixedly mounted between the two rotating shafts 42. Four electric push rods 44 are detachably mounted in a ring array on the inner wall of the fixing frame 43. The pistons of the electric push rods 44... A spherical limiting seat 45 is detachably installed at each end. When the ceramic grinding wheel is placed in the middle of the fixed frame 43, by activating four electric push rods 44 (the simultaneous activation of the four electric push rods 44 is controlled by PLC programming), the piston ends of the electric push rods 44 extend or retract, which can bring the four spherical limiting seats 45 closer together or further apart. When the four spherical limiting seats 45 are close together, the ceramic grinding wheel to be ground can be pressed against each other, fixing the ceramic grinding wheel in the middle of the fixed frame 43. A protective sleeve 46 is fixedly installed on the outer wall of the spherical limiting seat 45. By setting the protective sleeve 46, in... During clamping, the side of the ceramic grinding wheel can be prevented from being worn. The fixed end of the electric push rod 44 is threadedly mounted with several No. 1 bolts 441. One end of the No. 1 bolts 441 is threadedly connected to the threaded hole on the inner wall of the fixed frame 43. The piston end of the electric push rod 44 is threadedly mounted with several No. 2 bolts 442. One end of the No. 2 bolts 442 is threadedly connected to the threaded hole on one side of the spherical limit seat 45. By setting the No. 1 bolts 441 and No. 2 bolts 442, the electric push rod 44 and the spherical limit seat 45 can be disassembled and installed separately, which is convenient for maintenance. A servo motor 47 is fixedly installed on one side of one of the frame plates 41. A rotating rod 48 is fixedly installed at the drive output end of the servo motor 47. A transmission gear 49 is fixedly installed at one end of the rotating rod 48 and the other end of one of the rotating shafts 42. The two transmission gears 49 are meshed and connected. By starting the servo motor 47, the drive shaft of the servo motor 47 can make the rotating rod 48 rotate. The rotating rod 48 can make the rotating shaft 42 rotate through the two transmission gears 49. The rotating shaft 42 can make the fixed frame 43 rotate, thereby making the ceramic grinding wheel in the middle of the fixed frame 43 flip so that the other end face of the ceramic grinding wheel is vertically upward, so that the grinding unit 3 can perform grinding processing on the other end face of the ceramic grinding wheel. A protective cover 491 is fixedly installed on one side of one of the frame plates 41. The two transmission gears 49 are located inside the protective cover 491. By setting the protective cover 491, the transmission gears 49 can be protected to prevent waste chips and dust from adhering to the transmission gears 49.

[0020] The worktable 1 is equipped with a support unit 5, which includes a support plate 51. The axis of the support plate 51 is vertically aligned with the center point of the fixed frame 43. By setting the support plate 51, the ceramic grinding wheel can be supported before clamping and during grinding, thereby improving the stability of the ceramic grinding wheel. A cylinder 52 is fixedly installed on the worktable 1. The piston end of the cylinder 52 is fixedly installed on the lower surface of the support plate 51. By activating the cylinder 52, the piston end of the cylinder 52 extends and retracts, which can make the support plate 51 rise and fall vertically (the cylinder 52 retracts when the fixed frame 43 is flipped). A protective pad 53 is fixedly installed on the upper surface of the support plate 51. By setting the protective pad 53 on the support plate 51, the end face of the ceramic grinding wheel can be prevented from being worn.

[0021] Working principle: Before processing the ceramic grinding wheel, the operator first starts the cylinder 52, which extends the piston end of the cylinder 52. The cylinder 52 causes the support plate 51 and the protective pad 53 to rise vertically. After the support plate 51 rises to the lowest point of the spherical limit seat 45, the cylinder 52 is closed. Then the ceramic grinding wheel is placed on the protective pad 53, and the support plate 51 and the protective pad 53 support the ceramic grinding wheel. Subsequently, the operator simultaneously activates four electric push rods 44, causing the piston ends of the four electric push rods 44 to extend and push the four spherical limit seats 45 closer to each other. The four spherical limit seats 45 and the four protective sleeves 46 press the ceramic grinding wheel against each other, so that the ceramic grinding wheel is pressed against the middle of the fixed frame 43. Then, the grinding unit 3 is controlled by the moving unit 2 to descend vertically and move horizontally to perform a comprehensive grinding process on the upper end face of the ceramic grinding wheel. After the grinding of the upper surface of the ceramic grinding wheel is completed, the operator first controls the grinding unit 3 to reset via the moving unit 2, then starts the cylinder 52 to retract the piston end of the cylinder 52, controlling the support plate 51 to descend and reset. Then, the servo motor 47 is started, and the drive shaft of the servo motor 47 causes the rotating rod 48 to rotate. The rotating rod 48 causes the rotating shaft 42 to rotate via two transmission gears 49. The rotating shaft 42 causes the four electric push rods 44 and the four spherical limit seats 45 to flip via the fixed frame 43. The ceramic grinding wheels between the four spherical limit seats 45 flip synchronously, so that the lower surface of the ceramic grinding wheel is vertically upward. Then, the cylinder 52 is started again to raise the support plate 51 to support the ceramic grinding wheel, allowing the grinding unit 3 to grind the other end surface of the ceramic grinding wheel.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
