Description
Technical field
The internal diameter eccentricity fine adjustment formula cutter that the present invention is used to penetrate through axis drilling belongs to the technical field of machining, specifically relates to
And perforation axis drilling processing cutter.
Background technique
Axis is penetrated through when carrying out drilling processing with cutter, tolerance always zero curve, but requirement is 0- in technology processing
0.2(unit), zero curve influences whether matching requirements in the later period, and the drilling internal diameter of cutter be it is certain, can not be finely adjusted.Cause
It is necessary to design a kind of cutter that processing internal diameter is fine-tuning for this.
Summary of the invention
The present invention overcomes the shortcomings of the prior art, technical problem to be solved are as follows: provides a kind of for penetrating through axis
The internal diameter eccentricity fine adjustment formula cutter of drilling, easy to use, the range of work is wide, high-efficient.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention are as follows: the internal diameter for penetrating through axis drilling is eccentric
Fine adjustment type cutter, including outer sleeve, adjustment partially set, interior cutter shaft and hold out against stud, the side of outer sleeve is equipped with fastening thread hole, adjusts
Whole inclined set is the tube-in-tube structure that the inner wall center of circle and the outer wall center of circle are deviateed, and adjusts set side partially and be equipped with and pass through for hold out against that stud passes through
Port, the openings correspond to fastening thread hole, and interior cutter shaft is the cylindrical cutter shaft that one end is equipped with cutter head, hold out against stud through tight
Gu threaded hole and openings simultaneously compress interior cutter shaft, outer sleeve is stretched out outside as rotation end in adjustment set one end partially.
Side is equipped with horizontal section in the middle part of the interior cutter shaft, and the horizontal section corresponds to fastening thread hole, and puller bolt is logical
It crosses and holds out against the fixed interior cutter shaft of horizontal section.
The rotation end that adjustment set partially stretches out outside outer sleeve is equipped with the rotation outer rim for clutching rotation.
The stud that holds out against is that built-in stud and stud top center are equipped with more rib slots.
Compared with the prior art, the invention has the following beneficial effects: the present invention can oneself by adjusting the rotation covered partially
By adjusting the internal diameter in processed hole, technology processing request is reached, and realize the rapid changing knife of small range processing, process model
Enclose wide, high-efficient, and since the present invention is restructured on the basis of cutter is original, converted products reaches matching requirements, and is transformed
It is at low cost.
Detailed description of the invention
The present invention will be further described in detail with reference to the accompanying drawing；
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the C-C of Fig. 1 to structural schematic diagram；
Fig. 3 is the structural schematic diagram that the present invention tunes up processing hole internal diameter on the basis of Fig. 1；
In figure: 1 is outer sleeve, and 2 be adjustment set partially, and 3 be interior cutter shaft, and 4 be fastening thread hole, and 5 is hold out against stud, and 6 be openings,
7 be horizontal section, and 8 be rotation outer rim.
Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiments of the present invention, instead of all the embodiments；Based on the embodiments of the present invention, ordinary skill people
Member's every other embodiment obtained without creative efforts, shall fall within the protection scope of the present invention.
As shown in Figs. 1-2, the present invention is used to penetrate through the internal diameter eccentricity fine adjustment formula cutter of axis drilling, including outer sleeve 1, adjustment
Partially set 2, interior cutter shaft 3 and hold out against stud 5, the side of outer sleeve 1 is equipped with fastening thread hole 4, and adjusting set 2 partially is the inner wall center of circle and outer
The tube-in-tube structure that the wall center of circle is deviateed, and adjust 2 sides of set partially and be equipped with for holding out against the openings 6 that stud 5 passes through, the openings 6
Corresponding fastening thread hole 4, interior cutter shaft 3 are the cylindrical cutter shaft that one end is equipped with cutter head, hold out against stud 5 through 4 He of fastening thread hole
Openings 6 simultaneously compress interior cutter shaft 3, and outer sleeve 1 is stretched out outside as rotation end in the adjustment 2 one end of set partially.
The 3 middle part side of interior cutter shaft is equipped with horizontal section 7, and the corresponding fastening thread hole 4 of the horizontal section 7 holds out against spiral shell
Bolt 5 is by holding out against the fixed interior cutter shaft 3 of horizontal section 7.
The rotation end that adjustment set 2 partially stretches out outside outer sleeve 1 is equipped with the rotation outer rim 8 for clutching rotation.
The stud 5 that holds out against is that built-in stud and stud top center are equipped with more rib slots.
Application method:
As shown in Figure 1, present invention adjustment is when the most thick place of 2 walls of set is far from fastening thread hole 4 partially, at this time in cutter shaft 3 axis
It is overlapped with the axis of outer sleeve 1, the hole internal diameter that cutter is processed at this time is the internal diameter of cutter head, is minimum diameter A；
As shown in figure 3, rotation adjustment covers 2 certain angles partially, between 1 inner wall of interior cutter shaft 3 and outer sleeve far from fastening thread hole 4
