The combined cutter has the advantages that holing and chamfering can be finished by one time, the machining efficiency is high, the machining is convenient and the machining cost is reduced.
Description
Technical field
The utility model relates to a kind of cutter, is specifically related to the gang tool of a kind of automobile engine cylinder hole processing usefulness.
Background technology
In automobile manufacture industry, need be in the processing and manufacturing of automobile engine cylinder at machining hole, and chamfering is all wanted at the two ends in hole; The cutter majority of mechanical processing industry is or can only holes at present, or can only hole and process the chamfering of inlet side, can not process not-go-end chamfering and the two-way chamfering of through hole in the same way; Cause the same workpiece of processing need spend two procedures at least, and require to carry out loaded down with trivial details cutter changing process, cause working (machining) efficiency low; Waste time and energy, increase processing cost.Rose reamer exists chip removal not smooth in the prior art, is unfavorable for processing, and chamfering blade wears no resistance, and the blade exchange frequency is high, has reduced working (machining) efficiency, has increased processing cost.
Summary of the invention
For existing problem in the above-mentioned prior art of better solution, the novel gang tool that processing usefulness in a kind of automobile engine cylinder hole is provided of this use is so that disposable completion is holed and two-sided chamfering in an operation.
In order to realize the foregoing invention purpose, the technical scheme of the utility model is: the gang tool of a kind of automobile engine cylinder hole processing usefulness, wherein; Comprise cutter hub, be positioned at the drill bit of cutter hub front end, on the cutter hub at drill bit rear portion, be provided with a blade installing hole; And part is installed on the blade that installing hole also can shrink in installing hole at least, is provided with an elongated slot that extends vertically in the cutter hub rear end, the thimble that part is positioned at elongated slot and contacts with blade; Link to each other with thimble and be positioned at the elastic component of elongated slot; In the elongated slot of elastic component rear end, mandrel is installed, one of elongated slot of sealing and the fixture that links to each other with mandrel are provided with chip area in the cutter hub front portion.
The gang tool of the automobile engine cylinder hole processing usefulness in the utility model, wherein, said blade comprises preceding chamfering blades and back chamfering blades and is opened in the thimble sliding surface and the thimble limited step of blade rear end.
The gang tool of the automobile engine cylinder hole processing usefulness in the utility model, wherein, said chip area comprises the straight chip area that bit part is dark, the vortex-like shallow chip area and the middle transitional groove of back.
The gang tool of the automobile engine cylinder hole processing usefulness in the utility model, wherein, said cutter hub material is a high-speed steel, the blade material is PCD.
The gang tool of the automobile engine cylinder hole processing usefulness in the utility model, wherein, said fixture is a bolt.
The gang tool of the automobile engine cylinder hole processing usefulness in the utility model, wherein, said drill bit is inseparable formula element.
Beneficial effect: 1, the gang tool of the automobile engine cylinder hole of the utility model processing usefulness can disposable completion through hole and chamfering, and working (machining) efficiency is high.The gang tool of the automobile engine cylinder hole processing usefulness of the utility model is the drill bit that has rose reamer, and wherein blade has two chamfering blades, after the drill bit processing of cutter hub front end is portalled; Blade carries out chamfer machining near the chamfering blades of bit part, and blade shrink to get into the hole that has processed then, goes out behind the through hole blade and swells cutter and retreat; The rear portion chamfering blades is participated in processing; In the whole machining process process, disposable through hole and two-way chamfering or the not-go-end chamfering in the same way of machining, working (machining) efficiency improves.2, the gang tool of the automobile engine cylinder hole of the utility model processing usefulness helps processing, has reduced processing cost.The chamfering blade of the gang tool of the automobile engine cylinder hole processing usefulness of the utility model adopts the PCD material, has increased wearability, and the blade wearability is strong, reduces the replacing frequency of blade, and crudy is good, and working (machining) efficiency is high, has reduced processing cost; Cutter hub adopts high-speed steel in addition, and the chip area of cutter hub adopts shallow by being deep to, and chip removal is unobstructed, helps processing and carries out.
