Detailed ways

The specific embodiments of the present utility model will be further described in detail below with reference to the accompanying drawings.

Based on the deficiencies of the prior art, the utility model provides a high-precision adjustable sleeve boring tool. The specially designed sleeve boring tool body cooperates with the high-precision adjustable tool holder, so that the diameter accuracy of the sleeve boring tool can reach 0.01mm, and the length accuracy can reach 0.01mm. 0.1mm, realizing a variety of specifications of parts and products with one knife.

Referring to accompanying drawing 1, its specific structure is as follows:

The left end of the cutter body 1 is relatively narrow, which is the clamping end for positioning the cutter body, and the right end is the blade mounting end. Avoidance or accommodation when machining bosses or convex shafts.

A tool holder 7 is arranged on the inner wall of the slot hole 9 or in the groove of the inner wall, and the tool holder blade 6 is positioned on the tool holder 7. The radial feed position of the tool holder blade can be adjusted by adjusting the radial adjustment screw 4 of the tool holder. It is set to protrude into different positions in the slot hole 9 to meet the different requirements of the outer diameter of the boss during the processing of the boss.

On the left side of the tool holder 7, an inclined surface 10 is provided, and the screw head of the axial adjustment screw 2 of the tool holder is pressed against the inclined surface 10. When the screw is tightened, a force to the right in the figure is generated, which in turn acts on the tool holder 7 and Drive the adjustment of the feed position of the tool holder blade along the axial direction, so that the blade can act on the height position corresponding to the boss during the processing of the boss.

Wherein, the entire tool holder 7 after adjusting the position is fixed in the inner wall (referring to the side wall) of the slot hole 9 or the groove on the inner wall through the tool holder locking screw 3, and only the blade of the final tool holder blade 6 is required to be protruding It is enough to further meet the requirements of the outer diameter size of the processed boss or convex shaft in the slot hole.

Of course, the adjustment structure of radial adjustment can also be in the form of screw pressing the inclined surface against the tool holder, and then fixing the tool holder.

That is, the tool holder 7 is fixed on the tool body 1 by the tool holder locking screw 3. When in use, first loosen the tool holder locking screw 3, and adjust the tool holder axial adjustment screw 2 to increase or decrease the tool axial dimension 8 (Fig. Marked is the possible limit size, there is a corresponding allowance in actual use), the adjustment accuracy reaches 0.1mm, adjust the tool holder radial adjustment screw 4 to increase or decrease the tool radial dimension 5, the adjustment accuracy reaches 0.01mm, reaching After the dimensional accuracy of the parts is required, lock the tool holder locking screw 3 to complete the adjustment of the high-precision adjustable sleeve boring tool.

The high-precision adjustable sleeve boring tool provided by the utility model has the advantages of quick and easy installation and high precision.
