The top of the first guide slide rail 3 is welded to the axial machining position adjustment plate 4. Several angle marking lines are evenly distributed on one side of the axial machining position adjustment plate 4.

[0039] Here, the first guide slide rail 2 and the first guide slider 3, as well as the second guide slide rail 6 and the second guide slider 7, are all clearance fits;

[0040] Here, an adjustment handle 24 is welded to the bottom of the axial machining position adjustment plate 4 near the angle marking line, so that the axial machining position adjustment plate 4 can be pushed by the adjustment handle 24.

[0041] Here, a number of anti-slip textures are evenly distributed on the outer side of the anti-slip knob 22 to increase the friction between the hand and the anti-slip knob 22 when rotating it;

The axial machining position adjustment plate 4 and the feed angle adjustment base plate 5 are rotatably connected by the first shaft 10.

[0046] Please see Figure 1-3 As shown:

[0048] Here, a maximum depth adjustment rod 23 is slidably connected inside the bidirectional threaded rod 14 and located between the two external threaded sections, so as to rotate the bidirectional threaded rod 14 through the maximum depth adjustment rod 23 to adjust the distance between the first threaded sleeve 13 and the second threaded sleeve 15.

The bottom of the depth adjustment disc 18 and the outer side of the third shaft 19 are equipped with a positioning base plate 20, and the feed angle adjustment base plate 5 and the positioning base plate 20 are welded together.

[0051] Please see Figure 8 As shown:

[0052] The bottom of the depth adjustment disc 18 has a first corrugated surface, and the top of the positioning base plate 20 has a second corrugated surface, with the first and second corrugated surfaces transitioning into each other.

[0053] One specific application of this embodiment is:

[0054] The material is clamped and fixed on the CNC machine tool, the device is fixed near the material, and the alloy rotary cutting blade 9 is brought close to the material;

[0055] When the feed angle needs to be adjusted during material processing, rotate the anti-slip knob 22. Through the heat fusion connection between the anti-slip knob 22 and the positioning bolt 21, the anti-slip knob 22 drives the positioning bolt 21 to rotate, so that the positioning bolt 21 and the axial processing position adjustment plate 4 are no longer in contact, and thus the positioning bolt 21 no longer fixes the feed angle adjustment base plate 5.

[0056] Push the positioning bolt 21, and through the threaded connection between the feed angle adjustment base plate 5 and the positioning bolt 21, the positioning bolt 21 drives the feed angle adjustment base plate 5 to rotate. The feed angle of the alloy rotary cutter 9 is adjusted by the arrow mark on one side of the feed angle adjustment base plate 5 and the angle mark line on one side of the axial machining position adjustment plate 4.

[0057] After adjusting the feed angle of the alloy rotary cutter 9, rotate the anti-slip knob 22 in the opposite direction to make the positioning bolt 21 and the axial machining position adjustment plate 4 fit together, thereby fixing the positioning bolt 21 to the feed angle adjustment base plate 5.

[0058] When it is necessary to adjust the maximum depth of the alloy rotary cutter 9, rotate the maximum depth adjustment rod 23. Through the sliding connection between the bidirectional threaded rod 14 and the maximum depth adjustment rod 23, the maximum depth adjustment rod 23 drives the bidirectional threaded rod 14 to rotate. Through the threaded connection between the bidirectional threaded rod 14 and the first threaded sleeve 13, the bidirectional threaded rod 14 drives the first threaded sleeve 13 to move, further adjusting the distance between the first threaded sleeve 13 and the second threaded sleeve 15, thereby adjusting the maximum depth of the alloy rotary cutter 9.

[0059] When processing materials, pushing the adjusting handle 24 causes the axial machining position adjusting plate 4 to move through the welded connection between the adjusting handle 24 and the axial machining position adjusting plate 4. The axial machining position adjusting plate 4 is then rotated through the rotational connection between the axial machining position adjusting plate 4 and the feed angle adjusting base plate 5, causing the axial machining position adjusting plate 4 to move through the rotational connection between the axial machining position adjusting plate 4 and the feed angle adjusting base plate 5. The feed angle adjusting base plate 5 is then welded through the connection between the feed angle adjusting base plate 5 and the second guide rail 6, causing the feed angle adjusting base plate 5 to move through the rotational connection between the second guide rail 6 and the second guide slider 7, causing the second guide rail 6 to move through the rotational connection between the second guide slider 7 and the tool fixing base plate 8, causing the second guide slider 7 to move through the rotational connection between the second guide slider 7 and the tool fixing base plate 8, causing the tool fixing base plate 8 to move through the rotational connection between the tool fixing base plate 8 and the alloy rotary cutting blade 9, thereby adjusting the position of the alloy rotary cutting blade 9 in cutting the material.

[0060] Rotating the eccentric handle 17 causes the second linkage sleeve 16 to rotate due to the welded connection between the eccentric handle 17 and the depth adjustment disc 18, and the rotational connection between the second linkage sleeve 16 and the eccentric handle 17. The welded connection between the second linkage sleeve 16 and the second threaded sleeve 15 causes the second linkage sleeve 16 to move. The threaded connection between the second threaded sleeve 15 and the double-threaded rod 14 causes the second threaded sleeve 15 to move. The threaded connection between the double-threaded rod 14 and the first threaded sleeve 13 causes the double-threaded rod 14 to move. A threaded sleeve 13 moves, and through the welding connection between the first threaded sleeve 13 and the first linkage sleeve 12, the first threaded sleeve 13 drives the first linkage sleeve 12 to move. Through the rotational connection between the first linkage sleeve 12 and the second shaft 11, the first linkage sleeve 12 drives the second shaft 11 to move. Through the welding connection between the second shaft 11 and the tool fixing base plate 8, the second shaft 11 drives the tool fixing base plate 8 to move. Through the fixed connection between the tool fixing base plate 8 and the alloy rotary cutting blade 9, the tool fixing base plate 8 drives the alloy rotary cutting blade 9 to move, thereby adjusting the depth of the alloy rotary cutting blade 9 when processing materials.
