Abstract

The utility model discloses a reverse rimer of carbide shaping relates to machinery, including the cutter body, wherein the cutter body includes cutter arbor and tool bit, and wherein the cutter arbor includes thin pole and thick rod, and the centre of tool bit is equipped with the locating hole, and thin pole is worn in the locating hole, and the tool bit one is served and is equipped with the cutting edge what be close to thick rod, and the cutting edge be the plane in the one end of being close to the cutter arbor, and the tool bit is equipped with the round pin in the one end of keeping away from thick rod and fixes thin pole, sells mutually perpendicular with the cutter arbor. This rimer is used for limited little work piece in space or the drilling on the complicated workpieces. This rimer passes through the combination of tool bit and guide arm, effectively promotes cutter life, and the dismouting is light, workable complex type face, and the part can local change easily be decreased to split type structure, practices thrift the cost of charp tool, and the change is convenient, and the cutter arbor has certain commonality, for the user reduces the cutter kind, is convenient for manage.

Description

A kind of hard alloy molding reverse reamers
Technical field
This utility model is related to mechanical field and in particular to a kind of hard alloy molding reverse reamers.
Background technology
Counterbit is that the end face of device to hole carries out plane, cylinder, the conical surface and its processing of alloytype face.Machined go out hole on process When cylindrical counter sink, taper counter sink and end face boss, all using counterbit.
Standard counterbit is generally applicable, and part end face is no interfered, and is integral form or split type with shank, to part space Shan Little, the complicated parts in type face cannot be processed it is very difficult to meet Aero-Space parts at this stage to need the development trend of working position, Dismounting is complicated, easily hinders handss.
Narrow space or work piece are limited by Working position, need working position to have to process through multiple It is difficult to realize.
The establishment of molding anti-counterbit reverse drawing quick clamped cutting tool type of attachment, meets parts complicated type face process requirements, passes through Fast-assembling connects, and makes cutter head in small space easy removal, disposably reaches parts machining requirement, makes cutter manufacture reach one Frontier.
Content of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of hard alloy molding reverse reamers.
The technical problem that this utility model solves can employ the following technical solutions to realize: a kind of hard alloy molding is anti- To counterbit, including cutter hub, wherein said cutter hub includes knife bar and cutter head, and wherein knife bar includes thin bar and thick bar, the centre of cutter head Be provided with location hole, thin bar is through positioning in the hole, cutter head near thick bar one end on be provided with blade, blade near knife bar one Hold as plane, cutter head is provided with pin in the one end away from thick bar and fixes thin bar, and pin is perpendicular with knife bar.
Preferably, the outer fringe surface of described blade is the inclined-plane being obliquely installed, the diameter with diameter greater than cutter head of blade.
Preferably, described blade is being provided with arcuate groove on one end of guide rod.
Preferably, described arcuate groove includes arc groove and oval groove, and wherein circular trough is 1/4 circular arc, and oval groove is 1/4 Ellipse arc, on the inclined-plane of described blade, oval groove is in the plane of blade for circular trough.
Preferably, described knife bar is provided with chamfering.
Beneficial effect is: this counterbit is mainly used for the boring on the small workpiece of limited space or complex part.This counterbit By the combination of cutter head and guide rod, effectively lift cutter life, dismounting easily, can processed complex type face, split-type structural Can local replacing frangible portions, save the cost of charp tool, it is convenient to exchange, knife bar has certain versatility, be that user reduces cutter kind Class, is easy to manage.One end that the cutter head of this counterbit is proximate to knife bar is provided with blade so that this counterbit reduces sky needed for boring Between, meet more complicated parts.

Specific embodiment
Describe preferred implementation of the present utility model below in conjunction with the accompanying drawings in detail.
Fig. 1 and Fig. 2 shows a kind of a kind of specific embodiment of this utility model hard alloy molding reverse reamers: hard Alloy molding reverse reamers, including cutter hub, wherein said cutter hub includes knife bar 1 and cutter head 2, wherein knife bar 1 include thin bar 3 with thick Bar 4, the centre of cutter head 2 is provided with location hole 5, and thin bar 3 is through in location hole 5, and cutter head 2 is being provided with knife on one end of thick bar 4 Sword 6, being plane near one end of knife bar 1, cutter head 2 is provided with pin 7 in the one end away from thick bar 4 and fixes thin bar 3 blade 6, pin 7 with Knife bar 1 is perpendicular.
It should be noted that the outer fringe surface of described blade 6 is the inclined-plane being obliquely installed, blade 6 with diameter greater than cutter head 2 Diameter.It is being provided with arcuate groove 8 on one end of guide rod on described blade 6.Described arcuate groove 8 includes arc groove 9 and ellipse Groove 10, wherein circular trough are 1/4 circular arc, and oval groove 10 is 1/4 ellipse arc, and circular trough is on the inclined-plane of described blade 6, ellipse Circular groove 10 is in the plane of blade 6.Described knife bar 1 is provided with chamfering.
First knife bar 1 is passed through workpiece 11 hole, then by the opposite side from workpiece 11 hole for the cutter head 2 and knife bar 1 gap tight fit, lead to Cross pin 7 to be connected with knife bar 1. due to the effect of centrifugal force, counterbit is locked by rotary torsion, so that cutter is dismantled freely.
This counterbit is mainly used for the boring on the small workpiece 11 of limited space or complex part 11.This counterbit passes through cutter head 2 with the combination of guide rod, effectively lift cutter life, dismounting easily, can processed complex type face, split-type structural can local more Change frangible portions, save the cost of charp tool, it is convenient to exchange, and knife bar 1 has certain versatility, be that user reduces tool category, be easy to Management.One end that the cutter head 2 of this counterbit is proximate to knife bar 1 is provided with blade 6 so that this counterbit reduces boring requisite space, full The more complicated parts of foot.
Based on above-mentioned, this counterbit adopts cutter head 2 and knife bar 1 to connect the use of cutter form, can meet Aero-Space zero The high request of part surface to be machined, the processing reaching solving limited space parts disposably machines, effectively save Processing cost, improves the production efficiency of workpiece 11 machining, is that field of machining has opened up new markets.
The foregoing is only embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, every The equivalent structure made using this utility model description and accompanying drawing content or equivalent flow conversion, or be directly or indirectly used in Other related technical fields, are all included in the same manner in scope of patent protection of the present utility model.
