[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0018] like Figures 1 to 4As shown, this utility model discloses a grinding disc shaping device for a steel ball grinding machine. The technical solution includes a lower grinding wheel 1, a drive motor below the lower grinding wheel 1, an upper grinding wheel 2 above the lower grinding wheel 1, a grinding wheel receiving plate 201 attached to the upper grinding wheel 2, the grinding wheel receiving plate 201 being fixed to a connecting plate 3, the connecting plate 3 being connected to a vertical guide mechanism 13, a notch 14 being provided on the upper grinding wheel 2 and the grinding wheel receiving plate 201, a fixing rod 5 being provided on the grinding wheel receiving plate 201 at the notch 14, a bearing 6 being slidably connected to the fixing rod 5 to assist the rotation of the sliding sleeve 8, a spring 7 being below the bearing 6, and the sliding sleeve 8 being slidably connected to the fixing rod 5 above the bearing 6, the sliding sleeve 8 having a step 803 inside the sliding sleeve 8, the bearing 6 being located at the step 803, and a platform at the bottom of the fixing rod 5. Step 2 501, spring 7 is located between step 2 501 and bearing 6, fixed rod 5 has a thread at the top, and adjusting nut 9 is connected to fixed rod 5 through the thread. By rotating adjusting nut 9, sliding sleeve 1 8 moves downward, and spring 7 is used to provide upward support force for sliding sleeve 1 8, realizing a small adjustment of the height of shaping cutter head 11. Sliding sleeve 1 8 has a connecting rod 801 on the side, and sliding sleeve 2 802 at the other end of connecting rod 801. Sliding rod 10 is slidably connected inside sliding sleeve 2 802. There is a locking screw 12 between sliding rod 10 and sliding sleeve 2 802. By loosening locking screw 12, the height of shaping cutter head 11 can be quickly adjusted. Scale 1001 is engraved on the surface of sliding rod 10, and shaping cutter head 11 is at the bottom end of sliding rod 10.

[0019] The working principle of this utility model is as follows: When the steel ball grinding machine grinds steel balls for a long time, the grooves of the steel balls on the lower grinding wheel 1 will become deeper and deeper. In severe cases, the upper grinding wheel 2 and the lower grinding wheel 1 may be separated, resulting in damage to the grinding wheel. At this time, the upper grinding wheel 2 is lifted by the vertical guide mechanism 13, and the shaping cutter head 11 is turned to the notch 14 by holding the sliding sleeve 802. First, the locking screw 12 is loosened to adjust the height of the shaping cutter head 11. After the adjustment is completed, the locking screw 12 is tightened. Then, the shaping cutter head 11 is slightly adjusted by rotating the adjusting nut 9. When the shaping cutter head 11 contacts the lower grinding wheel 1, the scale 1001 is observed and the adjusting nut 9 is rotated to record the shaping amount of the lower grinding wheel 1. At this time, the sliding sleeve 802 is held and swung back and forth to make the shaping cutter head 11 perform friction shaping on the lower grinding wheel 1.
