[0021] The present invention will be further described below with reference to specific embodiments. See below for details. Figure 1 —4:

[0022] This utility model provides a grinding wheel cleaning device, which includes a drive motor mounted on the grinding wheel 1 to be cleaned, a frame, or a spindle. For example, the drive motor is mounted on the housing of the grinding wheel 1 to be cleaned. The spindle is used to mount the grinding wheel 1 to be cleaned. The cleaning grinding wheel 2 is mounted on the rotating shaft 3 of the drive motor and is driven to rotate by the rotating shaft 3. One end of the rotating shaft 3 extends out of the cleaning grinding wheel 2 and is provided with a limiting member 4. A spring 5 is sleeved on the rotating shaft 3 between the cleaning grinding wheel 2 and the limiting member 4, and the two ends of the spring 5 respectively abut against the cleaning grinding wheel 2 and the limiting member 4. During cleaning, the cleaning grinding wheel 2 is attached to the cleaning surface of the grinding wheel 1 to be cleaned. The cleaning grinding wheel 2 is made of the same material as the grinding wheel 1 to be cleaned.

[0023] The above structure can clean the surface of the grinding wheel in a timely manner. In addition, the spring 5 of this invention can apply a certain pressure to the cleaning grinding wheel 2, ensuring that the cleaning grinding wheel 2 can be tightly attached to the cleaning surface of the grinding wheel 1 being cleaned during the cleaning process, thereby improving the cleaning effect. Moreover, the spring 5 has a certain elasticity, which can play a buffering role during the cleaning process, avoiding the rigid structure between the cleaning grinding wheel 2 and the grinding wheel 1 being cleaned, and reducing wear or damage caused by excessive pressure or vibration.

[0024] In this invention, the limiting member 4 is a nut, and a screw part is correspondingly provided at the end of the rotating shaft 3. The nut is screwed onto the screw part, and the tension of the spring 5 can be adjusted by adjusting the position of the nut on the screw part. The limiting member 4 can also be replaced by a retaining ring.

[0025] In order to prevent dust and impurities in the coolant from being adsorbed onto the surface of the cleaning grinding wheel 2 during the grinding process, thereby affecting the cleaning effect, the cleaning grinding wheel 2 of this utility model is provided with a grinding wheel cover 6, and a rear cover 7 is provided at the rear end of the grinding wheel cover 6, and the spring 5 is located inside the rear cover 7.

[0026] Specifically, the end of the grinding wheel cover 6 connected to the rear cover 7 is an open end. The rear cover 7 includes an end plate 8, a first cylinder 9 located on both sides of the end plate 8, and a second cylinder. The outer end of the first cylinder 9 is closed, and the inner cavities of the first cylinder and the second cylinder are interconnected. The diameter of the first cylinder 9 is smaller than the diameter of the end plate 8. The second cylinder is inserted into the open end of the grinding wheel cover 6, and the grinding wheel cover 6 and the second cylinder are connected by fasteners. After installation, the corresponding part of the spring 5 and the limiting part 4 are located in the inner cavity of the first cylinder 9, and the first cylinder 9 also makes it convenient for workers to hold the rear cover 7 during disassembly and assembly.

[0027] Similarly, a motor housing 10 is provided outside the drive motor.

[0028] like Figure 3 and Figure 4 As shown, the cleaning grinding wheel 2 is provided with a mounting joint, which includes a groove 11 on the inner wall of the cleaning grinding wheel 2 and a protrusion 12 extending out of the outer wall of the cleaning grinding wheel 2. There are two or more threaded holes distributed circumferentially on the protrusion 12, and the mounting joint is provided with a through hole 13 for the rotating shaft 3 to pass through.

[0029] Correspondingly, a connecting joint is fixed on the rotating shaft 3. The connecting joint is provided with a slotted protrusion. During installation, the slotted protrusion engages in the slotted groove 11, and the cleaning grinding wheel and the rotating shaft are fixed by screws screwed onto the protrusion 12.

[0030] The above connection allows the cleaning wheel 2 to be quickly aligned and fixed on the rotating shaft 3.
