Abstract
The invention discloses a chamfering knife for double faces of a through hole. The chamfering knife is composed of a knife handle (1), a knife bar body (2), two blades (3) and an elastic closing groove (4), wherein an in-hole guide body (5) is arranged at the front end of the knife bar body (2); the surface of the in-hole guide body (5) is set as an inclined surface; the outer diameter of the in-hole guide body (5) corresponds to the inner hole of a machined workpiece; the elastic closing groove (4) is formed in the center of the interior of the knife bar body (2); the two blades (3) symmetric to each other are arranged outside the knife bar body (2) in a sleeving manner; when the in-hole guide body (5) enters the inner hole of the machined workpiece, the blades (3) enter the inner hole of the machined workpiece and chamfer and de-bur the hole surface of the inner hole of the machined workpiece by virtue of the own elastic strength of the knife bar body (2).
Description
Technical field
The present invention 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 invention provides a kind of through hole Double-side rounding cutter, it is convenient mounting and clamping not only, and can complete the two-sided processing of endoporus.
Present invention employs 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 present invention has following beneficial effect: have employed above technical scheme, the front end of knife bar body of the present invention 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 hand-hole guide way inclined-plane of the present invention is 6-10 °, can play guide effect like this.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the A-A sectional view of Fig. 1.
Detailed description of the invention
In fig. 1 and 2, the invention 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.
