Abstract
The utility model discloses a kind of through hole Double-side rounding cutter, it is by handle of a knife (1), knife bar body (2), blade (3) and elastic closure groove (4) are formed, the front end of described knife bar body (2) is provided with hand-hole guide way (5), the surface of hand-hole guide way (5) is set to inclined-plane, hand-hole guide way (5) external diameter is corresponding with the endoporus of institute's processing work, the center inner at knife bar body (2) has elastic closure groove (4), two symmetrical blades (3) are had in knife bar body (2) outer cover, when hand-hole guide way (5) enters in the endoporus of institute's processing work, blade (3) enters in the endoporus of institute's processing work and relies on the hole face of elastic strength to the endoporus of institute's processing work of knife bar body (2) self to carry out chamfering and deburring.
Description
Technical field
The utility model relates to a kind of through hole Double-side rounding cutter.
Background technology
The endoporus that can not complete in the cutter in traditional machine-building is two-sided, and particularly little hole wall chamfering, repaiies burr.The scope of application reduces greatly.
Summary of the invention
The utility model provides a kind of through hole Double-side rounding cutter, and it is convenient mounting and clamping not only, and can complete the two-sided processing of endoporus.
The utility model have employed following technical scheme: a kind of through hole Double-side rounding cutter, it is by handle of a knife, knife bar body, blade and elastic closure groove are formed, the front end of described knife bar body is provided with hand-hole guide way, the surface of hand-hole guide way is set to inclined-plane, hand-hole guide way external diameter is corresponding with the endoporus of institute's processing work, elastic closure groove is had at the center of knife bar body inside, two symmetrical blades are had at knife bar external body cover, when hand-hole guide way enters in the endoporus of institute's processing work, chamfering and deburring are carried out in the face, hole that blade enters in the endoporus of institute's processing work the endoporus relying on the elastic strength of knife bar body self to institute's processing work.
The angle on described hand-hole guide way inclined-plane is 6-10 °.Described elastic closure well width is greater than the blade height of twice.Described blade is set to cambered blade, and the circumference exterior angle of cambered blade is chamfering.
The utility model has following beneficial effect: have employed above technical scheme, the front end of the utility model knife bar body is provided with hand-hole guide way, the surface of hand-hole guide way is set to inclined-plane, hand-hole guide way external diameter is corresponding with the endoporus of institute's processing work, elastic closure groove is had at the center of knife bar body inside, blade is had at knife bar external body cover, blade is set to cambered blade, the circumference exterior angle of cambered blade is chamfering, when hand-hole guide way enters in the endoporus of institute's processing work, chamfering and deburring are carried out in the face, hole that blade enters in the endoporus of institute's processing work the endoporus relying on the elastic strength of knife bar body self to institute's processing work, time like this in the front end hand-hole guide way access aperture of rose reamer, blade relies on the elastic strength of knife bar body self to hole surface chamfer and deburring, via hole after completing, access aperture opposite end chamfering and deburring, not only convenient mounting and clamping, and the two-sided processing of endoporus can be completed, blade via hole is the outside dimension relying on elastic shrinkage to change blade in addition, the circumference exterior angle of blade is through chamfered, can not produce foramen primum wall during via hole and cut and damage, naturally realization is opened after via hole, through hole back face chamfer cuts.Particularly when withdrawing, blade closes, and inner beta angle changes to approximate α degree angle, can reach chamfering and be similar to the product requirement number of degrees.The angle on the utility model hand-hole guide way inclined-plane is 6-10 °, can play guide effect like this.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Detailed description of the invention
In Fig. 1 and Fig. 2 kind, the utility model discloses a kind of through hole Double-side rounding cutter, it is by handle of a knife 1, knife bar body 2, blade 3 and elastic closure groove 4 are formed, the front end of described knife bar body 2 is provided with hand-hole guide way 5, the surface of hand-hole guide way 5 is set to inclined-plane, the angle on described hand-hole guide way 5 inclined-plane is 6-10 °, hand-hole guide way 5 external diameter is corresponding with the endoporus of institute's processing work, elastic closure groove 4 is had at the center of knife bar body 2 inside, described elastic closure groove 4 width is greater than the blade height of twice, two symmetrical blades 3 are had in knife bar body 2 outer cover, when hand-hole guide way 5 enters in the endoporus of institute's processing work, chamfering and deburring are carried out in the face, hole that blade 3 enters in the endoporus of institute's processing work the endoporus relying on the elastic strength of knife bar body 2 self to institute's processing work, blade 3 is set to cambered blade, the circumference exterior angle of cambered blade is chamfering.
