Abstract
The invention discloses a shock-absorbing boring cutter capable of machining a slender stepped hole. The shock-absorbing boring cutter comprises a clamping part, a large boring cutter bar, a small boring cutter bar, a small boring cutter, a shock-absorbing material, a large boring cutter, a sealing ring, a connecting bolt and a rear end cover, wherein the clamping part is arranged on the rear end of the large boring cutter bar; the small boring cutter bar is arranged on the front end of the large boring cutter bar; the small boring cutter is arranged on the front end of the small boring cutter bar; the large boring cutter is arranged on the large boring cutter bar; an annular slot is arranged inside the cutter bar for filling the shock-absorbing material; the sealing ring is arranged on the rear end of a shock-absorbing slot for sealing; the rear end cover is fixed by the connecting bolt; the large boring cutter and the small boring cutter can designed to be detachable. According to the scheme of the invention, the shock-absorbing material is arranged inside the cutter bar, so as to prevent shock of the cutter bar from affecting machining precession while a slender hole is machined; two boring cutters are arranged, so that the cutters are not needed to be changed while the stepped hole is machined, thereby avoiding an influence of cutter changing to coaxiality and precision of a workpiece.
Description
Technical field
The present invention relates to a kind of cutter, but refer in particular to a kind of damping boring cutter of processing slim shoulder hole, belong to the metal cutting tool technical field.
Background technology
In machining, in the processing to axiality elongated orifices of having relatively high expectations and the shoulder hole of forming than macropore, generally adopt first processing slim hole, macropore is processed in tool changing again, and this processing method axiality just can not get guaranteeing; And when the processing slim hole, because knife bar is long, knife bar can produce vibration; Both influenced the crudy in hole; The surface in the hole that processes is prone to ripple, can't reach the requirement of product surface roughness, influences the service life of cutter again; Mostly the shock-dampening method that in the past adopted is to strengthen the knife bar diameter or reduces the lathe rotating speed and the depth of cut, understands waste material like this and reduces production efficiency.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: but a kind of damping boring cutter of processing slim shoulder hole has been proposed.
But technical solution of the present invention is achieved in that a kind of damping boring cutter of processing slim shoulder hole, comprises clamping part, big boring bar, little boring bar, little boring cutter, vibration-absorptive material, big boring cutter, sealing ring, attachment screw, rear end cap; Said big boring bar rear end is provided with clamping part, and front end is provided with little boring bar; Said little boring cutter is installed in the front end of little boring bar; Said big boring cutter is installed on the big boring bar; Offer cannelure in the said knife bar, be used for filling vibration-absorptive material; Said sealing ring is installed in the rear end of damping groove, plays the effect of sealing; Said rear end cap is fixed through attachment screw;
Preferably, said big boring cutter, little boring cutter are designed to dismountable form;
Preferably, said vibration-absorptive material is flexible materials such as polyurethane.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
But the damping boring cutter of a kind of processing slim shoulder hole of the present invention owing to little boring cutter, big boring cutter are installed on the same knife bar, need not adopt the method for tool changing like this when processing shoulder hole, the coaxial accuracy of the shoulder hole of processing is improved; Owing in the knife bar vibration-absorptive material is housed, be flexible materials such as polyurethane, elasticity is strong; The absorbability of impact power is strong; When the processing slim hole, avoid like this because the long generation vibration of knife bar to the influence of processing dimension and roughness, is better guaranteed processing dimension.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
But accompanying drawing 1 is the cutaway view of front view of the damping boring cutter of a kind of processing slim shoulder hole of the present invention;
Accompanying drawing 2 is but that the B of damping boring cutter of a kind of processing slim shoulder hole of the present invention is to cutaway view;
But accompanying drawing 3 is the stereogram of the damping boring cutter of a kind of processing slim shoulder hole of the present invention;
Wherein: 1, clamping part; 2, big boring bar; 3, little boring bar; 4, little boring cutter; 5, vibration-absorptive material; 6, big boring cutter; 7, sealing ring; 8, attachment screw; 9, rear end cap.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
But the damping boring cutter of the of the present invention a kind of processing slim shoulder hole shown in accompanying drawing 1-3 comprises clamping part 1, big boring bar 2, little boring bar 3, little boring cutter 4, vibration-absorptive material 5, big boring cutter 6, sealing ring 7, attachment screw 8, rear end cap 9; Said big boring bar 2 rear ends are provided with clamping part 1, are used for being clamped on the lathe, and front end is provided with little boring bar 3; Said little boring cutter 4 is installed in the front end of little boring bar 3, and little boring cutter 4 is dismountable; Said big boring cutter 6 is installed on the big boring bar 2, and big boring cutter 6 is dismountable; Offer cannelure in the said knife bar, be used for soft vibration-absorptive materials 5 such as filled polyurethane; Said sealing ring 7 is installed in the rear end of damping groove, plays the effect of sealing; Said rear end cap 9 is fixing through attachment screw 8; Boring cutter bar rotation drives the boring cutter cutting workpiece, and when processing aperture, boring cutter continues to coming to process macropore, and after surface of the work was passed to boring cutter bar to the reaction force of boring cutter when the processing slim hole, flexible again absorbed power was avoided the vibration of knife bar.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
But the damping boring cutter of a kind of processing slim shoulder hole of the present invention owing to little boring cutter, big boring cutter are installed on the same knife bar, need not adopt the method for tool changing like this when processing shoulder hole, the coaxial accuracy of the shoulder hole of processing is improved; Owing in the knife bar vibration-absorptive material is housed, be flexible materials such as polyurethane, elasticity is strong; The absorbability of impact power is strong; When the processing slim hole, avoid like this because the long generation vibration of knife bar to the influence of processing dimension and roughness, is better guaranteed processing dimension.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
