[0007] In actual use, the dressing roller is used to grind the outer edge and end face of the grinding wheel; the upper diamond pen is used to grind the inner concave surface of the grinding wheel.

[0008] The upper diamond pen is set at a position lower than the dressing roller, and the upper diamond pen and the rotating shaft are both inclined and the inclination directions are opposite, so that a larger processing area is formed between the upper diamond pen and the dressing roller to adapt to more grinding wheels of different sizes, which is more practical.

[0009] In the above-mentioned vertical grinding wheel dressing mechanism, the above-mentioned base includes a base body and a support plate fixed on the base body, the rotating shaft is rotatably arranged on the base body, the support plate is arranged parallel to the rotating shaft, and the support plate is located between the upper diamond pen and the rotating shaft; a positioning block is vertically fixed on the side of the support plate facing away from the rotating shaft, and the upper diamond pen is installed on the positioning block.

The positioning block is provided with a positioning hole matching the installation end. There are two positioning holes, and the two installation ends are respectively inserted into the two positioning holes to facilitate the installation of the upper diamond pen and the lower diamond pen.

[0013] In the above-mentioned vertical grinding wheel dressing mechanism, the transmission structure includes a driving wheel fixed to the lower end of the motor main shaft and a driven wheel fixed to the lower end of the rotating shaft, and the driving wheel and the driven wheel are connected by a belt to form a flexible connection between the motor and the rotating shaft, making the transmission more stable.

[0016] 1. Set the upper diamond pen to a position lower than the dressing roller. The upper diamond pen and the rotating shaft are both tilted and tilted in opposite directions, so that a larger processing area is formed between the upper diamond pen and the dressing roller to adapt to more grinding wheels of different sizes, which is more practical.

[0017] 2. A through hole, a screw and multiple threaded holes can be used to change the position of the support plate to adjust the position of the upper diamond pen, so as to better adapt to different types of grinding wheels and have better practicality. BRIEF DESCRIPTION OF THE DRAWINGS
