Abstract
An arc-shaped single-cut rotary file comprises a file head body and a file handle. The file head body is detachably connected with the file handle in a fastening mode, the top end of the file head body is an arc-shaped cylinder, a plurality of spiral file cuts are arranged on the surface of the file head body, the rotation direction of the spiral file cuts is single, the single rotation direction is opposite to the rotation direction of a part to be machined, chamfered grooves are formed in the spiral file cuts at intervals and form a plurality of spiral grooves in the file head body, and the rotation direction of the spiral grooves is opposite to the rotation direction of the spiral file cuts. The rotary file is reasonable in structural style and geometrical parameter, greatly improves the part machining process and is smooth in chip removal, cuttings on the surface of the part are not prone to adhering, therefore, the surface quality of the part is improved, the service life of the rotary file is prolonged, and the economic benefit is improved.
Description
Technical field
The utility model relates to a kind of filing instrument, is specially a kind of circular arc type single cut file rotary file.
Background technology
At present, for the file of processing aluminium alloy, steel part part repair with bruting process in the rotary file that uses on version and geometric parameter, to select be not very desirable, be not structure improper be exactly that angle is improper, cause with its polishing, while revising part, the smear metal of generation is difficult for discharging, easily stick to piece surface, not only affect surface quality of workpieces, rotary file is very easily wearing and tearing also, and shortened the service life of rotary file, cause waste of material, increase processing cost.
Utility model content
For the problems referred to above, the utility model provides a kind of circular arc type single cut file rotary file, this rotary file version and geometric parameter are reasonable, greatly improve the process of part, chip removal is unobstructed, makes piece surface smear metal be difficult for adhering to, thereby improves surface quality of workpieces, extend the service life of rotary file, increase economic efficiency.
For addressing the above problem, the technical scheme that the utility model adopts is:
A kind of circular arc type single cut file rotary file, comprise a file body, tang, a described file body is fastenedly connected with described tang removably, it is characterized in that: a described file body is that top is the cylinder of circular arc type, the surface of a described file body is provided with several screw type cut of files, the rotation direction of the described screw type cut of file is single rotation direction, described single rotation direction is contrary with the rotation direction of part to be processed, on the screw type cut of file every described, be intermittently provided with chamfered groove, described chamfered groove forms several screw type groove on a described file body, the rotation direction of described screw type groove is contrary with the rotation direction of the described screw type cut of file.
Preferably, the rotation direction of the described screw type cut of file is left-handed.
Preferably, the helical angle of the described screw type cut of file is 15 °.
Preferably, between adjacent two described spiral cut of files, form a grooved angle, described grooved angle is 70 °.
Preferably, the chamfered groove on the described screw type cut of file is 90 °.
Compared to the prior art a kind of circular arc type single cut file of the utility model rotary file has following beneficial effect:
1, the file body due to this rotary file is that top is the cylinder of circular arc type and has unidirectional rotation cut of file, while making to adopt this rotary file processing parts, round and smooth seamless.On the screw type cut of file, be intermittently provided with chamfered groove, the effect of chamfered groove can be counted as tooth, makes when machining part closely, and non-loosening, guarantees that cutting is smooth; Several chamfered grooves form several screw type groove on a file body, the rotation direction of screw type groove is contrary with the rotation direction of the screw type cut of file, this groove has chip removal effect, during processing parts, can make the smear metal of piece surface be difficult for adhering to, improve cutting state, reach good cutting effect, thereby improve surface quality of workpieces.
2, the rotation direction of the screw type cut of file is left-handed, it selects helical angle is 15 °, grooved angle between adjacent two spiral cut of files is 70 °, chamfered groove on the screw type cut of file is 90 °, make this rotary file there is rational structure and geometric parameter, by practical application, prove, choose the rotary file of above-mentioned angle in actual processing, obtained good processing effect.
3, this rotary file is simple in structure, is convenient to processing, and applying flexible, can meet the requirement of different processing parts materials, also can need to select the different tang of diameter according to supporting from air drill, practical.

The specific embodiment
As shown in Figure 1, 2, the utility model circular arc type single cut file rotary file, comprise a file body 1, tang 2, a file body 1 is connected with tang 2 is detachable, and a file body 1 is that top is the cylinder of circular arc type, and the surface of a file body is provided with several screw type cut of files, the rotation direction of several screw type cut of files is single rotation direction, and its rotation direction is contrary with the rotation direction of part to be processed.
Preferably, the rotation direction of the screw type cut of file is left-handed.
Preferably, the helical angle of several screw type cut of files is 15 °.
On every screw type cut of file, being intermittently provided with chamfered groove 3, as shown in Figure 4, is the chamfered groove schematic diagram after cutting along the screw type cut of file in circular arc type single cut file rotary file, and wherein preferably the angle β of chamfered groove 3 is 90 °.Several chamfered grooves 3 form several screw type groove on a file body, and the rotation direction of screw type groove is contrary with the rotation direction of the screw type cut of file.Between adjacent two spiral cut of files, form a grooved angle α, grooved angle α is 70 °.
Above embodiment is only exemplary embodiment of the present utility model, is not used in restriction the utility model, and protection domain of the present utility model is defined by the claims.Those skilled in the art in essence of the present utility model and protection domain, various modifications that the utility model is made or be equal to replacement and all drop in protection domain of the present utility model.
