It can be understood that the rotary drive 2 includes, but is not limited to, a motor, etc., and the rotary drive 2 can drive the grinding wheel 100 to be processed to rotate.

[0025] In this invention, the dressing body 4 is mounted on the processing table 3, and the grinding wheel 100 to be processed is mounted on the output end of the rotary drive 2. The dressing angle 41 of the dressing body 4 is in contact with the grinding wheel 100 to be processed. The rotary drive 2 drives the grinding wheel 100 to be processed to rotate, and the dressing body 4 can process an annular corner 101 corresponding to the dressing angle 41 on the grinding wheel 100 to be processed.

Moreover, the grinding wheel processing mechanism has low cost and small space occupation.

[0026] In addition, the tool dressing assembly includes a variety of tool dressing bodies 4, each of which is provided with a tool dressing angle 41. The tool dressing angle 41 on different tool dressing bodies 4 has a different shape. By selecting different tool dressing bodies 4, different sizes of R angles and different sizes of chamfers can be processed on the grinding wheel 100 to be processed, which improves the applicability and versatility of the grinding wheel processing mechanism.

[0027] In one embodiment, such as Figures 1 to 3 As shown, the grinding wheel processing mechanism also includes a dressing sleeve 5 with a insertion hole. The dressing sleeve 5 is mounted on the processing table 3, and the dressing body 4 is detachably mounted in the insertion hole. Understandably, the end of the dressing body 4 furthest from the dressing angle 41 is inserted into the insertion hole, and the dressing angle 41 is located outside the insertion hole. In this embodiment, the dressing body 4 is mounted on the processing table 3 via the dressing sleeve 5, and the disassembly and assembly operations between the dressing body 4 and the dressing sleeve 5 are simple.

[0028] In one embodiment, such as Figure 4 As shown, the side wall of the tool dressing sleeve 5 is provided with a fastening hole that connects to the insertion hole. The grinding wheel processing mechanism also includes a fastener 6 installed in the fastening hole, which presses against the tool dressing body 4 located in the insertion hole. It can be understood that the fastener 6 includes, but is not limited to, bolts, pins, etc., and the fastener 6 can be installed in the fastening hole by means of a threaded structure.

[0029] Specifically, after the dressing body 4 is inserted into the insertion hole, the fastener 6 is inserted into the fastening hole and presses against the side of the dressing body 4, thereby fixing the dressing body 4 in the insertion hole. Furthermore, the depth to which the dressing body 4 is inserted into the insertion hole is adjustable, facilitating contact between the dressing body 4 on the dressing sleeve 5 and the grinding wheel 100 to be processed.

[0030] In one embodiment, such as Figures 1 to 3 As shown, the grinding wheel processing mechanism also includes a base 7 with a mounting hole.

[0032] Another embodiment of this utility model also provides a grinding machine, including the above-described grinding wheel processing mechanism.

[0033] In one embodiment, the grinding machine further includes a base (not shown in the figure) with a first magnetic attraction part, and a second magnetic attraction part on the processing table 3.

Understandably, the first and second magnetic attraction parts can be two magnets, or one can be a magnet and the other an iron block. The processing table 3 can move on the base.

[0034] Specifically, the support base 1 moves the grinding wheel 100 to the designated coordinate position, and the processing table 3 moves the dressing body 4 directly below the grinding wheel 100. The height of the dressing body 4 is adjusted until it just contacts the grinding wheel 100 or maintains a gap distance. As the rotary drive 2 rotates the grinding wheel 100, the height of the grinding wheel 100 or the dressing body 4 is gradually adjusted until the dressing body 4 processes the required annular corner 101 on the grinding wheel 100. Then, the height of the grinding wheel 100 or the dressing body 4 is adjusted in the opposite direction to ensure a safe distance between the grinding wheel 100 and the dressing body 4 before the rotary drive 2 is turned off.
