Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] A grinding wheel dressing device, such as Figures 1-5 As shown, the system includes a base plate 1, a negative pressure pump 2, a rubber pad 3, a first fixing block 4, a rocker arm 5, a lead screw 6, a moving plate 7, a limit strip 701, a moving block 8, a cutter 9, a pressure sensor 10, a fixing plate 11, a motor 12, a gear 13, a limit block 14, a dust suction port 15, a second fixing block 16, a rotating rod 17, and a sensor cylinder 18. The negative pressure pump 2 is connected to the middle of the base plate 1, the rubber pad 3 is connected to the lower side of the base plate 1, the first fixing block 4 is connected to the upper right side of the base plate 1, the lead screw 6 is rotatably connected to the first fixing block 4, the rocker arm 5 is connected to the right side of the lead screw 6, the moving plate 7 is threadedly connected to the left side of the lead screw 6, the moving plate 7 is slidably connected to the base plate 1, the moving block 8 is slidably connected to the upper side of the moving plate 7, and the limit strip 701 is connected to the upper part of the moving plate 7. The movable block 8 is in contact with the blade 9 connected to the left side of the middle of the movable block 8. The fixed plate 11 is connected to the rear side of the movable plate 7. The motor 12 is connected to the right side of both the front and rear sides of the fixed plate 11. The gear 13 is connected to the output shaft of the adjacent motor 12. The gear 13 meshes with the movable block 8. The upper sides of both the front and rear sides of the fixed plate 11 are connected to the limit block 14. The pressure sensor 10 is connected to the middle of the movable block 8. The pressure sensor 10 is connected to the blade 9. The upper part of the movable plate 7 is also connected to the suction port 15, which is located below the limit bar 701. The upper middle side of the movable block 8 is connected to two second fixed blocks 16. A rotating rod 17 is rotatably connected between the second fixed blocks 16. A sensor cylinder 18 is rotatably mounted on the rotating rod 17.

[0021] When using this invention, first place the base plate 1 near the grinding wheel of the grinding machine to be dressed, then start the negative pressure pump 2 to fix the base plate 1 with negative pressure. The rubber pad 3 can play a sealing role, enhancing the fixing effect of the base plate 1. After the base plate 1 is fixed, shake the rocker arm 5 to make the lead screw 6 rotate on the first fixed block 4. Under the action of the thread, the moving plate 7 slides on the base plate 1, driving the moving plate 7 to move, causing the moving block 8 to move, so that the tool 9 moves and contacts the grinding wheel of the grinding machine. The pressure sensor 10 can detect the pressure on the tool 9, which is convenient for controlling the contact force between the tool 9 and the grinding wheel. After the tool 9 contacts the grinding wheel, start the grinding machine to make the grinding wheel rotate. At the same time, start the motor 12 to make the gear 13 rotate. Through the meshing movement of the gear 13 and the moving block 8, The moving block 8 is moved and limited by the limiting strip 701 and the limiting block 14. With the control of the starter motor 12 to rotate forward and backward, the moving block 8 slides back and forth, causing the tool 9 to slide back and forth on the surface of the grinding wheel to repair the surface of the grinding wheel. During the repair process, a vacuum cleaner can be connected through the dust suction port 15 to absorb the dust generated during the repair. After the repair is completed, the moving plate 7 can be moved out of a certain gap by the rocker arm 5, and then the rotating rod 17 can be rotated on the second fixed block 16, so that the induction cylinder 18 contacts the grinding wheel. During the rotation of the grinding wheel, the sensor detects the surface flatness of the grinding wheel to evaluate the repair quality. This achieves the function of automatically repairing the surface of the grinding wheel, improving the grinding quality of the repaired surface, and improving the repair efficiency.
