The purpose of this utility model is achieved in that
A kind of fine adjustment fine boring cutter, comprise the right boring cutter head of the cylindricality be arranged on main shaft handle, the side of fine boring cutter main body and bottom surface are respectively equipped with the radial hole installing sliding shoe and the pinhole led for sliding shoe, being provided with screwed hole and radial slot on the left of sliding shoe, compensating nut, disk spring for fixing fine-tuning nut with blocking.Fine adjustment screw is connected in fine boring cutter main body also by compensating nut by holder, disk spring and fine-tuning nut spin, the lateral surface of described fine adjustment screw is provided with circular scale ring, be provided with anti-rotation guiding mechanism between sliding shoe and fine boring cutter main body and finely tune retaining mechanism, sliding shoe, fine-tuning nut, disk spring and compensation nut can form auto-compensation, eliminate the slide assemblies in gap, wherein fine-tuning nut is fixed on sliding shoe, compensation nut and disk spring are stuck in the groove of sliding shoe, the gap that between fine adjustment screw and fine-tuning nut, thread abrasion produces can be eliminated under the pre-pressing force of disk spring by fine-tuning nut, thus ensure the precision of fine adjustment fine boring cutter.
The concrete structure of anti-rotation guiding mechanism is: the arranged outside in the middle part of sliding shoe has vertical slot, the fine boring cutter main body at corresponding vertical slot place is provided with pin-and-hole, the guide finger of the band conical surface is installed in pin-and-hole, promote guide finger to correct position, the alignment pin of locking above it makes its position fix thus reaches the effect of accurately guiding.
Connection between fine adjustment screw and holder: with open slot in holder, directly inserts in the cannelure of fine adjustment screw.
The utility model gives prominence to compared to existing technology and useful technique effect is:
1, sliding shoe of the present utility model, fine-tuning nut, disk spring and compensation nut can form can auto-compensation, eliminate the slide assemblies in gap, wherein: fine-tuning nut is fixed on sliding shoe, compensation nut and disk spring are stuck in the groove of sliding shoe, the gap that between fine adjustment screw and fine-tuning nut, thread abrasion produces can be eliminated under the pre-pressing force of disk spring by fine-tuning nut, thus ensures the precision of fine adjustment fine boring cutter.
2, the concrete structure of anti-rotation guiding mechanism of the present utility model is: the arranged outside in the middle part of sliding shoe has vertical slot, and the fine boring cutter main body at corresponding vertical slot place is provided with pin-and-hole, is provided with the guide finger of the band conical surface in pin-and-hole.Promote guide finger to correct position (sliding shoe can only move forward and backward and can not rotate), the alignment pin of locking above it makes its position fix thus reaches the effect of accurately guiding.
3, the connection between fine adjustment screw of the present utility model and holder: with open slot in holder, directly inserts in the cannelure of fine adjustment screw.Avoid traditional connected mode, more reliable and more stable.
4, simple, the stable performance of accessory of the present utility model, working strength are good, are suitable for the lathe of various model, have wide market prospects.

Detailed description of the invention
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, see Fig. 1-Fig. 3;
A kind of fine adjustment fine boring cutter, be arranged on the right boring cutter head of the cylindricality on main shaft handle, the side of fine boring cutter main body 1 and bottom surface are respectively equipped with the radial hole installing sliding shoe 2 and the pinhole led for sliding shoe, being provided with screwed hole and radial slot on the left of sliding shoe 2, compensating nut 7, disk spring 6 for fixing fine-tuning nut 5 with blocking.Fine adjustment screw 9 is connected in fine boring cutter main body 1 by holder 8 and also spins by compensating nut 7, disk spring 6 and fine-tuning nut 5, the lateral surface of described fine adjustment screw 9 is provided with circular scale ring, anti-rotation guiding mechanism is provided with between sliding shoe 2 and fine boring cutter main body 1, regulate fine adjustment screw 9 to drive sliding shoe 2 to move forward and backward and reach required size, then the screw 10 that is locked.
Embodiment 2: as illustrated in figures 4-5, embodiment 2 is substantially the same manner as Example 1, its difference is that the square sliding shoe in embodiment 2 instead of the concentric stroking motion block in embodiment 1, and eliminates anti-rotation guiding mechanism (square sliding shoe self has guide function).
Embodiment 3: as shown in figs 6-8, embodiment 3 is substantially the same manner as Example 1, and its difference is that the sliding shoe central authorities of embodiment 3 have cylindrical hole, can change the knife bar of different size in cylindrical hole, thus processes the hole varied in size.
