[0017] The following further elaborates the present utility model in combination with specific examples and the drawings.

[0018] Such as Figures 1-5As shown in the figure, a fine machining high-gloss cutter head with end face fine adjustment includes a cutter head body 1. Six evenly spaced concave surfaces 2 that recess towards the axis of the cutter head body 1 are provided on the outer edge of the cutter head body 1. A cutter head 3 and an adjusting block 4 located below the cutter head 3 are respectively installed on each concave surface 2. A through screw hole is provided in the middle of the cutter head 3 and is installed on the concave surface 2 through a fixing screw 31. The installation direction of the fixing screw 31 is in the circumferential direction of the cutter head body 1. Eight vertical guiding grooves 21 are provided on the contact surface between the concave surface 2 and the inner side of the cutter head 3. The cross-section of the vertical guiding groove 21 is serrated. A protruding strip that matches the vertical guiding groove 21 is provided on the inner side of the cutter head 3. The lower surface of the cutter head 3 is an upwardly concave surface 32 in the middle. The adjusting block 4 includes a lower sliding seat 41 and an upper sliding pillow 43. The sliding seat 41 is embedded in a transverse sliding groove 22 at the bottom of the concave surface 2. The lower part of the sliding pillow 43 straddles both sides of the transverse sliding groove 22. The upper part of the sliding pillow 43 is provided with a convex surface that matches the upwardly concave surface 32. The adjusting block 4 is connected to the concave surface 2 through an adjusting screw 42. The transverse sliding groove 22 is an inclined sliding groove with a lower outer side and a higher inner side. The inclination angle between the transverse sliding groove 22 and the end face of the cutter head body 1 is 15 degrees. When the adjusting block 4 moves inward along the transverse sliding groove 22, the cutter head 3 is jacked up. A diversion groove 11 that leads from the center to the concave surface 2 is provided on the end face of the cutter head body 1.

[0019] The outer side of the cutter head 3 on the side where the fixing screw 31 passes through is set as a concave surface that is concave in the middle relative to the left and right sides, which cooperates with the vertical guiding groove 21 to prevent the cutter head 3 from shifting radially along the cutter head body 1 after being fixed.

[0020] In the fine machining high-gloss cutter head with end face fine adjustment designed by the utility model, multiple evenly spaced concave surfaces 2 that recess towards the axis of the cutter head body 1 are provided on the outer edge of the cutter head body 1. A cutter head 3 and an adjusting block 4 located below the cutter head 3 are respectively installed on each concave surface 2, and each cutter head 3 is adjusted separately. The adjustment process of the cutter head 3 is as follows: As Figure 1, if it is necessary to adjust the cutter head 3 upward to the end face of the disk body 1, first loosen the fixing screw 31 of the cutter head 3, and then adjust the adjusting screw 42 of the adjusting block 4 clockwise. The adjusting screw 42 pushes the entire adjusting block 4 to move inward along the transverse chute 22. Since the transverse chute 22 is an inclined chute with a lower outer side and a higher inner side, the sliding pillow 43 on the upper part of the adjusting block 4 gradually moves upward, pushing the cutter head 3 to move upward. When the cutter head 3 moves upward, it moves upward along the vertical guiding groove 21. Then measure the height of the upper part of the cutter head 3 to see if it is adjusted to the appropriate height. Then tighten the fixing screw 31 to complete the height adjustment of the cutter head 3. If it is necessary to adjust the height of the cutter head 3 downward, similarly, first loosen the fixing screw 31, and then adjust the adjusting screw 42 counterclockwise. The adjusting screw 42 pushes the entire adjusting block 4 to move outward along the transverse chute 22. The sliding pillow 43 on the upper part of the adjusting block 4 gradually moves downward, and the cutter head 3 pressed on the sliding pillow 43 moves downward. Before tightening the fixing screw 31, it is best to press down the cutter head 3 at the same time so that the upper concave surface 32 at the lower part of the cutter head 3 abuts tightly against the sliding pillow 43, then measure the adjusted height, and finally tighten the fixing screw 31. The whole operation is very simple and convenient to adjust.
