[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0026] Various non-limiting embodiments of the present invention are described in detail below. Any number of elements in the accompanying drawings is for illustration and not for limitation, and any naming is only for distinction and does not have any limiting meaning. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0027] Example 1 like Figure 1-Figure 3 As shown, a grinding wheel dressing machine comprises a frame 1, on which a mounting mechanism for mounting a grinding wheel 9 to be processed and a dressing mechanism for dressing the grinding wheel 9 to be processed are mounted, and the mounting mechanism can drive the grinding wheel 9 to be processed to rotate so as to facilitate the dressing mechanism to perform dressing. The grinding wheel 9 to be processed in this embodiment is a special-shaped grinding wheel. The frame 1 is provided with two profiling members 2 which are arranged at intervals in the left and right directions and can be replaced, and the two profiling members 2 both have a conflicting sliding surface 21, and the conflicting sliding surface 21 is sequentially divided into a first straight sliding section 22, a profiling curve section 23 and a second straight sliding section 24, and the profiling curve section 23 is located between the first straight sliding section 22 and the second straight sliding section 24, and the profiling curve section 23 matches the outer contour of the grinding wheel 9 to be processed, and one of the two profiling curve sections 23 is convex and the other is concave, that is, in the left and right directions, the distance between the two conflicting sliding surfaces 21 is consistent. The profiling curve section 23 is a continuous smooth arc surface with multiple different bending directions.

[0028] In this embodiment, the first linear sliding section 22 and the second linear sliding section 24 are linear.

[0029] In other embodiments, the abutting sliding surface 21 may be divided into a first curved sliding section, a contoured curved section 23 and a second curved sliding section in sequence, wherein the first curved sliding section and the second curved sliding section are curved.

[0030] like Figure 1-Figure 3 As shown, the dressing mechanism in this embodiment includes a dressing shaft frame 3, a dressing motor 6 fixedly mounted on the dressing shaft frame 3, and a dressing grinding wheel 7 driven by the dressing motor 6. The dressing grinding wheel 7 is used to contact with the grinding wheel 9 to be processed and dress it. A sliding channel 4 is formed between the two profiling members 2. The dressing shaft frame 3 slides in the sliding channel 4. The left and right sides of the dressing shaft frame 3 are equipped with replaceable first guide keys 5. The two first guide keys 5 respectively contact the contact sliding surface 21 of the corresponding side profiling member 2, that is, the dressing shaft frame 3 is in contact with the contact sliding surface 21 through the two first guide keys 5 and can slide along the contact sliding surface 21. The frame 1 is equipped with a driving mechanism which is connected to the dressing shaft frame 3. The driving mechanism can drive the dressing shaft frame 3 to move along the abutting sliding surface 21 in the sliding channel 4, so that when the first guide key 5 abuts and slides to the contoured curve segment 23, the dressing grinding wheel 7 will dress the grinding wheel 9 to be processed, and the dressing is performed according to the curvature of the curved surface of the contoured curve segment 23.

[0031] The profiling curve section 23 of the profiling member 2 matches the grinding surface of the grinding wheel that meets the use requirements, so when the dressing shaft frame 3 moves in the sliding channel 4 between the two profiling members 2, the dressing grinding wheel 7 will dress the grinding wheel 9 to be processed into the shape of the corresponding profiling curve section 23. At the same time, the profiling member 2 is installed on the frame 1 in a detachable manner, for example, the profiling member 2 is fixed by bolts or by a clamping method. When it is necessary to process grinding wheels of different specifications, it is only necessary to replace the profiling member 2 of the profiling curve section 23 of the corresponding specification. It is simple and easy to use, which is convenient for grinding wheel dressing personnel, improves the efficiency of manual operation, reduces the requirements for the skill level of grinding wheel dressing personnel, and enables inexperienced employees to more easily dress qualified special-shaped grinding wheels.
