Detailed description of the invention
Describe embodiments of the present invention in detail below with reference to drawings and Examples, to the present invention, how application technology means solve technical problem whereby, and the implementation procedure reaching technique effect can fully understand and implement according to this.It should be noted that, only otherwise form conflict, each embodiment in the present invention and each feature in each embodiment can be combined with each other, and the technical scheme formed is all within protection scope of the present invention.
Specifically, the invention discloses the far-end micro-adjusting mechanism of the anti-boring and processing cutter of a kind of deep hole, and together with cutter the Principle Method of corrdinated adjustment.
Blades of cutting tools is designed to axis (slide bar) and radial (slide block) displacement converted mechanism.Knife bar end is designed to micromatic setting, and make it drive slide bar to realize far-end fine setting, cutter can feeding processing.Front end is contained in the support set on slide-bar, adds the long rigidity overhang of deep hole tools.
Specifically, shown in Fig. 1,2,3,4, a kind of far-end fine setting deep hole reverse boring cutter, comprising: a knife bar 10, shank is connected with handle of a knife; Knife bar 10 has cylindrical cavity hole 30, a slide bar 32 is loaded in cylindrical cavity hole 30, knife bar 10 offers first to run through square hole 20 and second and run through square hole 40, described first runs through in square hole 20, one threaded block 21 and a slide bar 32 are rigidly connected, and described threaded block 21 and a nut ring 13 are connected, calibration loop 12 is positioned at nut ring 13 one end, and locking nut 22 is positioned at nut ring 13 other end; Described second runs through square hole 40 is slidably connected in slide block 33 cooperation, and slide block 33 is engaged by helical teeth dish with a slide bar 32, and described slide block 33 is equipped with cutter head 34, cutter head 34 is equipped with blade 3537, to carry out positive boring and anti-boring cutting, runs through square hole 40 side, one screw 36 is set, for locking.
Further, preferably, described slide-bar 50 fills a support set 60, described support set 60 can rotate can slide with slide-bar 50.
Further, preferably, described knife bar 10 and slide bar 32 are split type or module connection structure.
Further, preferably, described calibration loop 12 adjusts and spacing described nut ring 13 with retaining ring 220.
Further, preferably, the described threaded block 21 that rotarily drives of described nut ring 13 moves vertically, and described threaded block 21 is with moving slide-bar 32 synchronizing moving, and described slide bar 32 promotes slide block 33 and moves radially.

Further, preferably, described knife bar 10 is connected with handle of a knife, is contained on boring and milling machine, or, be directly contained on lathe.
Operation principle of the present invention is as follows:
Nut ring 13 is limited between calibration loop 12 and retaining ring 22.Rotating nut ring 13, threaded block 21 moves vertically, and simultaneously with slide bar 32 synchronizing moving, slide block 33 is engaged by helical teeth groove with slide bar 32, and the axial displacement of such slide bar 32 promotes slide block 33 and is converted to radial displacement.Achieve the transmission of displacement.Nut ring 13 rotates one week, and threaded block 21 moves axially a pitch, so the displacement of slide block 33 and the angular displacement of nut ring 13, just have strict corresponding relation.In the middle of the present invention, calibration loop divides 100 lattice, and nut ring 13 rotates lattice corresponding slide block 33 displacement 0.01mm.So just achieve far-end fine setting, after adjustment, retaining ring 22 is locked, screw 36 is locked.
Owing to being the anti-boring of deep hole, knife bar overhangs longer, and rigidity is less, on front end slide-bar 50, installs support set 60, improves cutting rigidity, the draw ratio of this kind of knife bar, can reach times footpath, 15 times of footpath ~ 20.
In addition, the invention also discloses a kind of cutting process based on far-end fine setting deep hole reverse boring cutter, its concrete steps are as follows in detail:
A. cutter head 34 diameter is transferred to an initial value A to be less than and to enter aperture;
B. knife bar is entered in workpiece, support set 60 is delivered to precalculated position;
C. by the centre position of cutter head back to machining hole;
D. rotating nut ring 13, feed, the amount of feeding is the first cutter cutting-in ap;
E. retaining ring 22 is screwed, tightening screw 36;
F. the first cutter is cut in anti-boring or positive boring;
G. unclamp screw 36 and retaining ring 22, repeat d, e two sequence, cut the second cutter.Until preliminary dimension;
H. unclamp screw 36 and retaining ring 22, cutter head 34 diameter is transferred to an initial value A, screws retaining ring 22, fallen back on by knife bar outside workpiece, cutting completes.
After this invention takes such scheme, this cover cutter can use at three axle boring and milling machines, and makes screw mechanism have fine adjustment function.The axis of this cover cutter and radial displacement switching mechanism, the radial feed problem of deep hole position can be solved, far-end micro-adjusting mechanism can solve the precision problem of feed, front end is contained in the support set on slide-bar, add the long rigidity overhang of deep hole tools, the draw ratio of this kind of knife bar, can reach times footpath, 15 times of footpath ~ 20.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
