[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] like Figure 1-4As shown, a fine-adjustable boring tool structure provided by an embodiment of the utility model comprises a tool holder frame 1, a tool holder 2, a fine-adjustment mechanism 5, a mounting frame 6 and a blade 7. The fine-adjustment mechanism 5 comprises an adjusting seat 11, a threaded barrel 15, a threaded sleeve 16 and a threaded rod 18. A sliding groove 12 is provided on one side of the tool holder 2. The adjusting seat 11 is slidably installed in the sliding groove 12. A mounting groove 14 is provided on the other side of the tool holder 2. The mounting groove 14 is communicated with the sliding groove 12. The threaded barrel 15 is fixedly installed on the inner wall circumference of the mounting groove 14. The threaded sleeve 16 is threadedly installed in the threaded barrel 15. The threaded rod 18 is threadedly installed in the threaded sleeve 16. One end of the threaded rod 18 is fixedly connected to one end of the adjusting seat 11. A limiting mechanism 8 is provided on one side of the mounting groove 14. Two guide posts 26 are provided on one side of the limiting mechanism 8. Two sliding holes are provided on one side of the threaded sleeve 16. The threaded sleeve 16 is slidably installed on the two guide posts 2 through the two sliding holes. 6 circumferential side, the outer pitch of the threaded sleeve 16 is greater than the inner pitch of the threaded sleeve 16, the outer thread direction of the threaded sleeve 16 is opposite to the inner thread direction of the threaded sleeve 16, the limiting mechanism 8 includes a fixed sleeve 20, a rotating block 21, a limiting slider 23 and a rotating sleeve 24, the fixed sleeve 20 is fixedly installed on one side of the mounting groove 14, the rotating block 21 is fixedly installed on one end of the threaded cylinder 15, and the circumferential side of one end of the threaded cylinder 15 is located in the fixed sleeve 20, and the circumferential sides of the rotating block 21 and the fixed sleeve 20 are both provided with a plurality of limiting slide grooves 22, and two adjacent limiting slide grooves 22 are connected, the limiting slider 23 is fixedly installed on the circumferential side of the inner wall of the rotating sleeve 24, and the rotating sleeve 24 is sleeved on the circumferential sides of the rotating block 21 and the fixed sleeve 20, and the limiting slider 23 is slidably installed in two adjacent limiting slide grooves 22, a scale ring 19 is fixedly installed on one side of the mounting groove 14, and a pointer is fixedly installed on one side of the rotating sleeve 24, and the pointer corresponds to the scale ring 19.

[0024] Specifically, in the present embodiment, when it is necessary to fine-tune the positions of the mounting bracket 6 and the blade 7, the rotating sleeve 24 is pulled outward to drive the limiting slider 23 to slide into the limiting slide groove 22 on the rotating block 21. Then, the rotating sleeve 24 can drive the rotating block 21 to rotate through the limiting slider 23. The rotation of the rotating block 21 can drive the two guide columns 26 to rotate. The rotation of the two guide columns 26 can drive the threaded sleeve 16 to rotate. The threaded sleeve 16 can move along the threaded barrel 15 through its external thread. Then, the threaded sleeve 16 can drive the threaded rod 18 to move while moving and rotating. At the same time, the external pitch of the threaded sleeve 16 is greater than the internal pitch of the threaded sleeve 16, so that after the threaded sleeve 16 rotates one pitch, it drives the threaded rod 18 to move. The distance is the difference between the outer pitch of the threaded sleeve 16 and the inner pitch of the threaded sleeve 16. Then the movement of the threaded rod 18 can drive the adjustment seat 11, the mounting frame 6 and the blade 7 to move, so that the staff can accurately adjust the position of the mounting frame 6 and the blade 7. Among them, the diameter of the limiting slide groove 22 on the fixed sleeve 20 is smaller than the diameter of the limiting slide groove 22 on the rotating block 21, so that when the rotating sleeve 24 is reset, the limiting slider 23 moves to the limiting slide groove 22 on the fixed sleeve 20, and a section of the limiting slider 23 is still located in the limiting slide groove 22 on the rotating block 21, so that the rotating sleeve 24 can be limited, which improves the stability of the mounting frame 6 and the blade 7 after fine-tuning. At the same time, an elastic card bead structure is provided between the limiting slider 23 and the limiting slide groove 22.

[0025] The utility model provides a fine-adjustable boring tool structure, wherein a slideway 25 is provided at one end of a tool handle 2, a mounting frame 6 is arranged on the upper side of an adjusting seat 11, a blade 7 is mounted on one side of the mounting frame 6 by means of screws, the mounting frame 6 is slidably mounted in the slideway 25, a threaded slot 13 is provided on one side of the mounting frame 6 and the adjusting seat 11, a tool holder inner hexagonal bolt 10 is threadedly mounted between the two threaded slots 13, one end of the tool handle 2 is movably inserted in a tool handle frame 1, threaded holes 3 are provided on both sides of the tool handle frame 1, inner hexagonal bolts 4 are threadedly mounted in the threaded holes 3, fixed slots 9 are provided on both sides of the tool handle 2, and one end of two inner hexagonal bolts 4 are movably inserted in two fixed slots 9 respectively.

[0026] In another embodiment provided by the utility model, when the blade 7 needs to be replaced, the fixing of the mounting frame 6 can be released by loosening the hexagon socket bolt 10 of the tool holder using a tool, and then the mounting frame 6 and the blade 7 are removed, and a new mounting frame 6 and blade 7 are replaced, and the mounting frame 6 is fixed with the hexagon socket bolt 10 of the tool holder. When installing the knife handle 2, the knife handle 2 is inserted into the knife handle frame 1, and then the hexagon socket bolt 4 is rotated using a tool so that one end of the hexagon socket bolt 4 is inserted into the fixing slot 9 on one side of the knife handle 2 to complete the installation.

[0027] Working principle: When it is necessary to fine-tune the position of the mounting frame 6 and the blade 7, the fixing of the fine-tuning mechanism 5 by the limiting mechanism 8 is released, and then the fine-tuning mechanism 5 is driven to move by the limiting mechanism 8, so that the fine-tuning mechanism 5 can drive the mounting frame 6 and the blade 7 to move, and through the fine-tuning mechanism 5, the staff can accurately adjust the position of the mounting frame 6 and the blade 7. After the adjustment is completed, the limiting mechanism 8 is reset to limit and fix the fine-tuning mechanism 5, thereby completing the fixation of the mounting frame 6 and the blade 7, and improving the stability of the mounting frame 6 and the blade 7 after fine-tuning.
