Abstract
The invention provides a fine-adjustment fine boring unit which comprises a main body, an anti-rotating jack catch, a thread dial and a thread cutter bar. The main body is provided with a stepped inner hole. One end of the stepped inner hole contacts with and is located with a flange end face of the thread dial. The other end of the stepped inner hole contacts with and is located with an axial locating face of the anti-rotating jack catch. The wall of the main body is provided with a through spiral groove which is uniformly arranged along the circumferential direction. The thread dial is provided with a threaded inner hole. An annular deformation groove provided with thin grooves is arranged in an outer cylindrical face far from the flange end face. Pull claws which stretch out along the axial direction and are uniformly arranged along the circumferential direction are arranged on the same side of the axial locating face of the anti-rotating jack catch. The pull claws are located in the stepped inner hole of the main body and are clamped with the side face of the annular deformation groove of the thread dial. The thread cutter bar is connected with the threaded inner hole of the thread dial through threads. The distance between locating faces at two ends of the main body is larger than the sum of the distance between a flange locating face of the thread dial and a clamping side face on the annular deformation groove and the distance between the locating face of the anti-rotating jack catch and a clamping face of each pull claw. The fine-adjustment fine boring unit is simple and reliable in structure, low in manufacturing cost, long in service life, and high in adjusting accuracy.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As shown in Figures 1 to 8, the invention discloses a kind of fine setting right boring unit, comprise main body 2, anti-rotation claw 1, thread dial 3, nut arbor 4, described main body 2 has ladder endoporus, and the flange contact of one end and thread dial 3 is located, and the other end contacts with anti-rotation claw 1 axial locating surface and locates, the penetrating helicla flute 5 main wall having a section be circumferentially evenly arranged, described thread dial 3 has threaded interior hole, there is flange one end, on the external cylindrical surface of the other end, have cyclic deformation groove 8, cyclic deformation groove 8 place has the stria 6 that two is 180 ° perpendicular to axis, opening direction, and the degree of depth of stria 6 is greater than this face of cylinder, place radius, described anti-rotation claw 1 has the locating surface contacted with main body 2, and homonymy has the pulling claw 11 axially stretched out, and pulling claw 11 is circumferentially uniform, and engage with the side of the cyclic deformation groove 8 of thread dial 3, pulling claw 11 is arranged in the shoulder hole of main body 2, nut arbor 4 is arranged in the threaded interior hole of thread dial 3 by screw thread, main body two ends locating surface 15, distance between 16 is greater than thread dial flange locating surface 19 arrives pulling claw snap-latch surface 18 distance sum to distance and the anti-rotation claw locating surface 17 of cyclic deformation groove engaging side 20, when the pulling claw 11 of anti-rotation claw 1 is engaged to after in thread dial cyclic deformation groove 8, main body 2 is stressed upon helicla flute 5 place and elastic deformation occurs, outside axial force is applied respectively to thread dial 3 and anti-rotation claw 1, under the effect of main body 2 elastic force, the pulling claw 11 of anti-rotation claw 1 strains the side of thread dial cyclic deformation groove 8, make thread dial 3, from stria 6, axial deformation occur, thus the thread pitch eliminated between thread dial 3 and nut arbor 4, there is the scale of mark mutual alignment main body 2 and thread dial 3 flange joint portion.It is little that helicla flute 5 position has distortion, and the advantage that elastic force is large, thread dial 3, anti-rotation claw 1 and interconnective dominant structural moieties thereof are all positioned at main body 2, compact overall structure, and outward appearance is neat and artistic.
Preferably, main body 2 outer surface has cannelure 21, and described helicla flute 5 is arranged in cannelure 21, by the wall thickness at cannelure 21 adjustable helicla flute 5 place, thus the elastic force at adjustable screw groove 5 place.
Preferably, there is seam one end that main body 2 and thread dial 3 are located, and the locating flange of thread dial 3 is arranged in seam, and end flat appearance is attractive in appearance, and scale can be marked on the end face of both junctions, is easy to observe.
Preferably, there is the convex key 12 axially stretched out one end that main body 2 contacts with anti-rotation claw 1, and anti-rotation claw 1 has the keyway 10 matched with it, anti-rotation claw 1 can better be connected with main body 2, can not relatively rotate.
Preferably, there are outer-hexagonal or tetragonal in the axis outside of thread dial 3 flange, tool into rotation thread dial 3 easy to use, thus regulates nut arbor 4.
Preferably, nut arbor 4 afterbody has feather key, and the section shape of feather key is bar shaped, rectangle, rhombus or ellipse, and anti-rotation claw 1 end face has the hole 9 suitable with feather key, can prevent nut arbor 4 from rotating.
Preferably, there are fixing hole 14 in main body 2 and thread dial 3 contact jaw edge, in order to the circumferential position of stationary body 2.
Preferably, in main body 2, the wall thickness at helicla flute 5 place is 0.1-50mm, and the width of helicla flute 5 is 0.1-25mm, length 0.1-50mm, determines the elastic force needed for main body 2 according to the size of nut arbor 4, the wall thickness etc. at thread dial stria 6 place.
Preferably, helicla flute 5 quantity is 2 to 50, determines according to main body 2 size and required elastic force.
Preferably, pulling claw 11 end has radially to projecting inward barb, and the snap-latch surface of pulling claw 11 is positioned on barb, and snap-latch surface is perpendicular to axis, and pulling claw 11 quantity is 2 to 20.
During use, first nut arbor 4 and thread dial 3 are screwed on earth by screw thread pair, secondly anti-rotation claw 1 is loaded main body 2 one end inner, the axial locating surface of anti-rotation claw 1 and main body 2 end contact are located, makes convex key 12 coordinate with keyway 10 simultaneously, then nut arbor 4 and thread dial 3 are loaded as a whole main body 2 other end inner, now should ensure that the feather key of nut arbor 4 afterbody is consistent with the direction, hole 9 of anti-rotation claw 1 end face, last by specific purpose tool, helicla flute 5 uniform in compress body 2, slowly the pulling claw 11 in anti-rotation claw 1 is pressed in the cyclic deformation groove 8 of thread dial 3, due to main body two ends locating surface 15, distance between 16 is greater than thread dial flange locating surface 19 arrives pulling claw snap-latch surface 18 distance sum to distance and the anti-rotation claw locating surface 17 of cyclic deformation groove engaging side 20, now helicla flute 5 pressurized is made to produce elastic deformation, outside power is applied to anti-rotation claw 1 and thread dial 3, owing to having stria 6 in cyclic deformation groove 8, under pulling claw 11 pairs of cyclic deformation groove 8 side action, thread dial 3 produces axial deformation from cyclic deformation groove 8, correspondingly eliminate the thread pitch between thread dial 3 and nut arbor 4, when needing the axial distance adjusting nut arbor 4, only need by rotating the axial distance of thread dial 3 with regard to adjustable nut arbor 4, concrete distance confirms with the curved scale district 13 in main body 2 by the circular scale line 7 in thread dial 3.
Certainly; the present invention also can have other various embodiments; when not deviating from the present invention's spirit and essence thereof; those of ordinary skill in the art can make various corresponding change and distortion according to the present invention, but these change accordingly and are out of shape the protection domain that all should belong to the claim appended by the present invention.
