A spring 9 is fixed, and one end of the spring 9 away from the U-shaped frame 8 is fixed to the right side of the diamond grinding wheel 3. The spring 9 is located on the outer wall of the slide rod 4. The opposite surface of the square hole of the U-shaped frame 8 is provided with an anti-loosening component. The hollow column 2 is fixedly installed with the outer wall of the machine tool shaft 1 with bolts. A chamber is provided in the middle of the left side of the diamond grinding wheel 3. The left edge of the diamond grinding wheel 3 is arranged in an inclined surface, and the right edge of the diamond grinding wheel 2 7 is arranged in an inclined surface, so that the grinding wheel is in the gap between the diamond grinding wheel 1 3 and the diamond grinding wheel 2 7. The distance between the diamond grinding wheel 1 3 and the diamond grinding wheel 2 7 can be flexibly adjusted, so that the diamond grinding wheel 1 3 and the diamond grinding wheel 2 7 can grind grinding wheels of different thicknesses at the same time, avoiding the difficulty of the equipment in grinding grinding wheels of different thicknesses and causing poor grinding effect.

[0031] The anti-loosening component includes a round roller 11, which is rotatably mounted on the opposite side of the square hole of the U-shaped frame 8. A support plate 12 is fixed above the front and back sides of the hollow column 2, and a cross plate 13 is fixed at one end of the support plate 12 away from the hollow column 2. The cross plate 13 is located inside the square hole of the U-shaped frame 8, and slide grooves are provided on both sides of the back side of the cross plate 13. A U-shaped plate 14 is slidably mounted on the inner wall of the slide groove of the cross plate 13, and an arc-shaped spring piece 15 is fixed in the middle of the back side of the cross plate 13. The U-shaped plate 14 is on the movement trajectory of the arc-shaped spring piece 15, and the round roller 11 is located on the back side of the U-shaped plate 14. Anti-skid particles are arranged on the back side of the U-shaped plate 14, and the U-shaped plate 14 is tightly against the round roller 11, thereby slowing down the moving speed of the diamond grinding wheel 27 to avoid damage to the diamond grinding wheel 27 during grinding, resulting in poor equipment use effect.

[0032] When in use, the machine tool shaft 1 supports the hollow column 2, the hollow column 2 supports the diamond grinding wheel 3, the grinding wheel is placed on the left side of the diamond grinding wheel 3, the CNC machine tool is started, the machine tool shaft 1 starts to rotate forward, the machine tool shaft 1 drives the hollow column 2 to rotate forward, the hollow column 2 drives the diamond grinding wheel 3 to rotate forward, so that the diamond grinding wheel 3 grinds the grinding wheel. Since the thickness of the grinding wheels to be grinded is different, it is easy to cause poor effect of grinding grinding wheels of different thicknesses. When the grinding wheel is placed on the left side of the diamond grinding wheel 3, the electric telescopic rod 10 is started, the telescopic end of the electric telescopic rod 10 moves to the right, the telescopic end of the electric telescopic rod 10 drives the U-shaped frame 8 to move to the right, and the round pad of the U-shaped frame 8 drives The slide bar 4 moves to the right, and in the process that the round pad of the U-shaped frame 8 moves to the right, the spring 9 on the round pad of the U-shaped frame 8 contracts under the action of elastic force. Under the elastic force of the spring 9, the movement speed of the slide bar 4 is slowed down, and the slide bar 4 drives the diamond grinding wheel 2 7 to move to the right, so that the grinding wheel is in the gap between the diamond grinding wheel 1 3 and the diamond grinding wheel 2 7. The distance between the diamond grinding wheel 1 3 and the diamond grinding wheel 2 7 can be flexibly adjusted, so that the diamond grinding wheel 1 3 and the diamond grinding wheel 2 7 can grind grinding wheels of different thicknesses at the same time, preventing the equipment from grinding grinding wheels of different thicknesses with poor effect, thereby avoiding the problem that the equipment is difficult to grind grinding wheels of different thicknesses and causing poor grinding effect.

[0033] When the telescopic end of the electric telescopic rod 10 drives the U-shaped frame 8 to move to the right, the support plate 12 supports the cross plate 13, and the cross plate 13 supports the arc-shaped spring piece 15. When the U-shaped frame 8 moves to the right, the U-shaped frame 8 moves to the right and drives the round roller 11 to move to the right. Under the action of friction, the round roller 11 rolls on the U-shaped plate 14, and the arc-shaped spring piece 15 presses against the U-shaped plate 14 under the action of elastic force. During the grinding process of the equipment, the electric telescopic rod 10 is accidentally damaged, and the diamond grinding wheel 27 will instantly move to the left during the rotation and grinding process. At this time, the U-shaped plate 14 is tightly against the round roller 11, slowing down the moving speed of the diamond grinding wheel 27, preventing the equipment from being damaged and causing the diamond grinding wheel 27 to be damaged, thereby avoiding the problem of poor equipment use effect caused by the damage of the diamond grinding wheel 27 during the grinding process.

Under the action of gravity, the grinding oil flows onto the grinding wheel, so that the equipment can automatically apply the grinding oil to the grinding wheel before grinding the grinding wheel, so that the grinding wheel coated with the grinding oil has a better grinding effect, and avoids the inconvenience of applying the grinding oil when the equipment is grinding, resulting in insufficient grinding.

[0035] The oil supply mechanism 5 also includes a nozzle 55, which is fixed on the inner walls of the four circular holes of the round box 51.

The disc 54 is on the movement trajectory of the sponge block 52. The arc plate 57 is slidably set on the inner wall of the round box 51. The arc plates 57 are all slidably set on the opposite side of the nozzle 55. The arc plate 57 opens the nozzle 55 to allow the polishing oil to flow into the nozzle 55, and the nozzle 55 sprays out the polishing oil to avoid the waste of polishing oil when the equipment is not in use.

[0036] A water collecting mechanism 6 is arranged on the left side of the diamond grinding wheel 1 3, and the water collecting mechanism 6 comprises a circular groove cylinder 61, and the circular groove cylinder 61 is fixed on the left side of the diamond grinding wheel 1 3, and the circular groove cylinder 61 is slidably connected with the through hole of the diamond grinding wheel 2 7, and a slide groove is arranged on the outer wall of the circular groove cylinder 61, and a circular ring 62 is fixed on the inner wall of the through hole of the diamond grinding wheel 2 7, and a mesh cylinder 63 is fixedly installed on the left side of the inner wall of the circular groove cylinder 61.

[0037] The water collecting mechanism 6 also includes a round cover 64, which is fixed on the left side of the circular groove cylinder 61. A round hole is opened in the middle of the left side of the round cover 64. An L-shaped plate 65 is fixed on the left side of the diamond grinding wheel 27. A short rod 66 is fixed on the upper right side of the L-shaped plate 65. The short rod 66 is slidably connected to the round hole of the round cover 64.

At the same time, the diamond grinding wheel 13 supports the short column 53, and the short column 53 supports the disc 54. The sliding hole of the round box 51 slides on the short column 53, and the sponge block 52 contacts the disc 54 in the process of moving to the right. Under the action of the extrusion force, the disc 54 squeezes out the grinding oil of the sponge block 52, and the grinding oil flows out from the round hole of the round box 51. Under the action of gravity, the grinding oil flows onto the grinding wheel, so that the equipment can automatically apply grinding oil to the grinding wheel before grinding the grinding wheel, so that the grinding wheel coated with grinding oil has a better grinding effect, preventing the equipment from being inconvenient to maintain the grinding wheel before grinding, thereby avoiding the problem of insufficient grinding caused by the inconvenience of applying grinding oil during grinding.

[0039] When the sliding hole of the round box 51 slides on the short column 53, the short column 53 supports the vertical plate 56, the vertical plate 56 supports the arc plate 57, the round box 51 moves to the right on the arc plate 57, the arc plate 57 opens the nozzle 55, and the polishing oil flows into the nozzle 55.

When the equipment is rotating, under the action of centrifugal force, the cold water will be thrown out from the gap between the ring 62 and the circular groove cylinder 61, so that the cold water flows out between the diamond grinding wheel 13 and the diamond grinding wheel 27.
