Abstract
A deep-hole lathe tool comprises a cylindrical tool bar. A circular tool head which has a hollow structure is welded at the front end of the circular tool bar. An inner hole of the circular tool bar is communicated with the circular tool head. The deep-hole lathe tool has the following beneficial effects: improved durability, capability of discharging chips, improved machining precision and surface roughness of the workpiece.
Description
Technical field
The utility model relates to a kind of deep hole lathe tool.
Background technology
Working shaft-like, hole type part are to cut with regular turning tool basically on CA6140 type lathe.But when running into deep hole processing class part; These regular turning tools just are difficult to disposable completion cutting task; Because in working angles, with producing a large amount of heat in metal cuttings, cooling fluid can not flow to cutting place; These heat in metal cuttings will be delivered in cutter and the workpiece, thereby influence the durability of cutter and the dimensional accuracy in hole; And the cutting edge inclination of regular turning tool and front clearance are definite values, can not be in working angles conversion cutting edge inclination and front clearance at any time, can not control at any time smear metal outflow direction (conversion cutting edge inclination) and with the friction condition (front clearance) of machined surface; And in cutting process, smear metal can not in time be got rid of in the air, will influence roughness.More than these reasons, all will influence the raising of machining accuracy of service life and the workpiece of cutter.
Summary of the invention
Add to exist man-hour and influence cutter life and the low problem of workpiece machining accuracy carrying out deep-hole type parts with regular turning tool at present for solving, the utility model provides a kind of long service life and the high deep hole lathe tool of workpiece machining accuracy.
The technical scheme of the utility model:
The deep hole lathe tool is characterized in that: comprise a circular knife bar, the front end of said circular knife bar is welded with round cutterheads, and said circular knife bar is a hollow structure, and the endoporus of said circular knife bar is communicated with round cutterheads.
Further, said round cutterheads is the round cutterheads of carbide alloy.
The course of work of the utility model: in process, the flexible pipe mouth is inserted in the circular knife bar endoporus, makes the cooling fluid power directly be poured into cutting place; The heat in metal cutting liquid that is cooled is timely taken away; From deep hole, flow out, the cutter temperature is reduced, improve the durability of cutter.Simultaneously, smear metal also will be along with cooling fluid is discharged in deep hole; Be the outflow direction of control smear metal, as long as rotary cutter, the cutting edge inclination on the round cutterheads will change, and the front clearance on the cutter also can change simultaneously, has directly changed the friction condition with machined surface, thereby has improved the machining accuracy and the surface roughness of workpiece.
The effect intentionally of the utility model: improved the durability of cutter, can in time discharge smear metal, improved the machining accuracy and the surface roughness of workpiece.

Fig. 1 is the front view of the utility model.
Fig. 2 is the vertical view of the utility model.
Fig. 3 is the left view of the utility model.
Fig. 4 is the application sketch map of the utility model.
The specific embodiment
With reference to Fig. 1-4, the deep hole lathe tool comprises a circular knife bar 1, and the front end of said circular knife bar 1 is welded with round cutterheads 2, and said circular knife bar 1 is a hollow structure, and the endoporus 3 of said circular knife bar 1 is communicated with round cutterheads 2.
Said round cutterheads 2 is round cutterheadses of carbide alloy.
The course of work of the utility model: in process, flexible pipe mouth 4 is inserted in circular knife bar 1 endoporus 3, makes the cooling fluid power directly be poured into cutting place; The heat in metal cutting liquid that is cooled is timely taken away; From deep hole, flow out, the cutter temperature is reduced, improve the durability of cutter.Simultaneously, smear metal also will be along with cooling fluid is discharged in deep hole; Outflow direction for the control smear metal; As long as according to the curved arrow rotary cutter shown in Fig. 4; Cutting edge inclination on the round cutterheads 2 will change; Simultaneously the front clearance on the cutter also can change, and has directly changed the friction condition with machined surface, thereby has improved the machining accuracy and the surface roughness of workpiece.
The described content of this specification embodiment only is enumerating the way of realization of utility model design; Should not being regarded as of the protection domain of the utility model only limits to the concrete form that embodiment states, the protection domain of the utility model also reach in those skilled in the art according to the utility model design the equivalent technologies means that can expect.
