[0018] The following further describes the present application in detail Figures 1 - 3 in conjunction with the attached drawings.

[0019] The embodiment of the present application discloses an automatic dressing mechanism for the thickness of a grinding wheel. Referring to Figures 1 - 3 , it includes a driving assembly 1 and a dressing assembly mounted on the driving assembly 1. The driving assembly 1 is used to drive the dressing assembly to move. The dressing assembly includes a carriage 21, a base 22, a dressing rod 23 and a dressing tool 24. The carriage 21 is mounted on the driving assembly 1, the base 22 is fixed to the side of the carriage 21, one end of the dressing rod 23 is rotatably connected to the side wall of the base 22, an arc trapezoidal groove 221 is formed on the side wall of the base 22 close to the dressing rod 23, a stud 231 is fixed on the surface of the dressing rod 23, the stud 231 can move along the arc trapezoidal groove 221, and a locking nut is screwed on the stud 231. The dressing tool 24 is fixed on the dressing rod 23, and the cutting surface of the dressing tool 24 can be in vertical contact with the surface of the grinding wheel;

[0020] The driving assembly 1 is a servo screw guide slide table. The carriage 21 is fixed on the slide table of the servo screw guide slide table. The servo screw guide slide table is controlled by a servo motor, and the servo motor has high precision.

[0021] Referring to Figure 1 and Figure 2 , one end of the trimming rod 23 away from the base 22 has a mounting portion 232 for mounting the trimming tool 24. The shape of the mounting portion 232 is a parallelogram, and the trimming tool 24 is a diamond tool.

[0022] Referring to Figure 1 and Figure 2 , a fine adjustment screw rod 3 is also threadedly connected to the trimming rod 23. One end of the fine adjustment screw rod 3 can abut against the base 22. The fine adjustment screw rod 3 is arranged between the stud 231 and the trimming tool 24. By providing the fine adjustment screw rod 3, a supporting force can be provided to the trimming rod 23 to offset the gap between the trimming rod 23 and the base 22, so that the overall service life of the trimming mechanism can be improved.

[0023] The implementation principle of an automatic grinding wheel thickness trimming mechanism according to an embodiment of the present application is as follows:

[0024] During use, according to the angle of the grinding wheel, the angle of the trimming rod 23 is adjusted so that the cutting surface of the trimming tool 24 is vertically attached to the grinding wheel. Then, the trimming rod 23 is fixed to the base 22 through a locking nut. After that, the servo screw rod guide slide can accurately drive the trimming tool 24 to feed or retract. When feeding, the cutting edge of the trimming tool 24 can trim the grinding wheel to trim the grinding wheel to a suitable thickness. Since the trimming angle is fixed and the feeding direction is a straight line, the trimming quality can be guaranteed. Subsequently, as the outer diameter of the grinding wheel is consumed, the trimming mechanism will also synchronously increase the trimming compensation and will keep trimming until the end of the grinding wheel life, thus ensuring the stability of the entire grinding process.
