Fine setting right boring unit anti-rotation claw
The present invention relates to a kind of machine tool part, especially relate to a kind of fine setting right boring unit anti-rotation claw.
In field of machining, more and more higher along with Product Precision is required, to the adjustment precision of process toolRequire also more and more higher, existing right boring unit or to adjust precision low, or complex structure, adjusts precisionHigh fine setting right boring unit is substantially all imported product, expensive, has greatly increased the production cost of enterprise,Weaken the market competitiveness of China's engineering goods.
Summary of the invention
The present invention aims to provide a kind of fine setting right boring unit anti-rotation claw, for the precision micrometer adjustable device of boring cutter,It is simple and reliable for structure, long service life, low cost of manufacture.
Technical scheme of the present invention is a kind of fine setting right boring unit anti-rotation claw, and anti-rotation claw one end is provided with axleTo locating surface, axial locating surface homonymy is provided with the pulling claw stretching out vertically, and pulling claw is along circumferentially uniform, and pulling claw pushes upEnd is provided with radially to projecting inward barb.
Preferably, the barb snap-latch surface on described pulling claw is perpendicular to axis.
Preferably, described anti-rotation claw end outer surface is provided with keyway vertically.
Preferably, anti-rotation claw has location external cylindrical surface, location external cylindrical surface next-door neighbour axial locating surface.
Preferably, center, described anti-rotation claw end arranges porose.
Preferably, described hole be shaped as bar shaped, rectangle, rhombus or ellipse.
Preferably, inner side, described pulling claw end is inclined-plane, and all pulling claws inner side forms horn mouth.
Preferably, the each width of described pulling claw is 0.1-5mm, and thickness is 0.1-5mm, length 0.1—10mm。

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 4, the invention discloses a kind of fine setting right boring unit anti-rotation claw, anti-rotation clawOne end is provided with axial locating surface 6, and axial locating surface homonymy is provided with the pulling claw 3 stretching out vertically, pulling claw 3Along circumferentially uniform, pulling claw 3 tops are provided with radially to projecting inward barb 5. Elongated pulling claw 3 makes itEnd can produce larger radial deformation, is convenient to pack in fitted shaft, and the barb 5 on pulling claw 3 tops ensuresCan be fastened in fitted shaft and not come off tightly, simultaneously stressed even.
Preferably, the barb snap-latch surface 4 on pulling claw 3 is perpendicular to axis.
Preferably, anti-rotation claw end outer surface is provided with keyway 2 vertically, prevents and the part matchingRelatively rotate.
Preferably, anti-rotation claw has location external cylindrical surface 7, and location external cylindrical surface 7 is close to axial locating surface 6.
Preferably, center, anti-rotation claw end arranges porose 1.
Preferably, hole 1 be shaped as bar shaped, rectangle, rhombus or ellipse, while preventing from assembling and hole 1 fillsThe axle generation axial-rotation of joining.
Preferably, pulling claw 3 inner sides, end are inclined-plane, and all pulling claws 3 inner sides form horn mouth, are more convenient for drawingPawl 3 packs the axle matching into.
Preferably, the each width of pulling claw 3 is 0.1-5mm, and thickness is 0.1-5mm, length 0.1-10mm.
Preferably, the quantity of pulling claw 3 is 2-20.
Certainly, the present invention also can have other various embodiments, in the feelings that do not deviate from spirit of the present invention and essence thereofUnder condition, those of ordinary skill in the art can make according to the present invention various corresponding changes and distortion, but thisA little corresponding protection domains that all should belong to the appended claim of the present invention that change and be out of shape.
