Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the attached drawings.

As shown in fig. 1 to 5, a fine-tunable boring tool for machining a conical surface comprises a tool body 1, wherein a chamfer angle adjusting tool holder 2 and two conical surface adjusting tool holders 3 are respectively arranged on the tool body 1 in a circumferential array, and the fine-tunable boring tool comprises:

the chamfering adjustment tool chuck 2 includes a chamfering blade 21 driven to move in the axial direction;

the bevel adjustment clamp 3 includes a bevel blade 31 driven to maintain radial movement and axial movement.

Specifically, the chamfer adjusting tool holder 2 and the bevel adjusting tool holder 3 in the above embodiments each include an outer shell 100, a tool seat 102, and a base 103, and the chamfer insert 21 and the two bevel inserts 31 are respectively mounted on the three tool seats 102. How to realize the axial movement of the chamfer insert 21 and the radial movement and the axial movement of the tapered insert 31 in detail is realized by the following structure:

the tool post 102 is rotatably provided with a first screw 1031, and the outer shell 100 (specifically, an L-shaped structure, when the outer shell 100 is combined with the base 103, the vertical portion of the outer shell 100 is combined with the base 103, so that the horizontal portion is parallel to the base 103 and forms a sliding groove, and the tool post 102 slides in the sliding groove) is provided with a protruding portion in sliding fit with the first screw 1031. As can be seen from fig. 4 and 2, a hexagonal threaded hole is formed in an end surface of the first screw 1031 located outside the tool apron 102, and axial movement of the chamfer blade 21 and the conical blade 31 can be achieved by rotating the hexagonal threaded hole, so that a circumferential radius formed after rotation is adjustable;

a rotating shaft 1001 is arranged in a notch in the outer armor 100, a second screw 1002 is arranged on one side of the notch in a rotating mode, a protruding portion on the base 103 is arranged on the second screw 1002 in a threaded mode, and the rotating shaft 1001 and the second screw 1002 are in meshed transmission. Specifically, the meshing transmission refers to meshing transmission performed through two bevel gears, as can be seen from fig. 3 and fig. 5, in the embodiment, the end surface of the rotating shaft 1001 is a hexagonal thread groove, and the second screw 1002 is driven to rotate by using a gear transmission through operation of an internal hexagonal thread wrench, so as to realize radial movement of the tapered blade 31.

Among the above-mentioned technical scheme, the adjustment is convenient, and is swift, can directly carry out the regulation of tapering and chamfer size on the tool setting appearance. When the blade is worn, the blade can be directly replaced by a new blade without readjustment, so that the cutter is safe and reliable and is convenient to disassemble; in the processing process, the size is stable; can be repeatedly used, and the cost is reduced.

In the above embodiment, the two chamfer angle adjusting tool holders 2 and the conical surface adjusting tool holder 3 are arranged in parallel, and the side surface of the conical surface adjusting tool holder 3 is flush with the end surface of the cutter body 1.
