Description
Technical field
The utility model belongs to precision processing technology field, is specifically related to a kind of cylindrical cutter head wire rod quality of milling edge position-adjustable.
Background technology
Helical-lobe compressor has in mechanical field to be applied very widely, and rotor is the topmost parts of helical-lobe compressor.Spiral camber on screw rotor is formed through helix sweeping by the molded lines of rotor of complexity, and in order to ensure the high compression performance of compressor, the requirement on machining accuracy of screw rotor is very high.Therefore design spiral camber that rational tool sharpening goes out to meet precision and become an important research topic.
The milling cutter mainly wire rod quality of current moulding processing spiral camber, in Machining Technology to today that is efficient, high-precision, automation development, take Numeric Control Technology as the modern high accuracy of representative, the use of high efficiency lathe, the precision, cutting ability, functional reliability etc. of cutter are had higher requirement, the more and more difficult adaptive technique innovation of traditional Milling Process cutter, and indexable tool technology is exactly the cutting-tool engineering that can match with the modern machine of superior performance.
Wire rod quality is mainly based on indexable insert tip, throw away tip wire rod quality, hereinafter referred to as common disk milling cutter, wire rod quality such as the patent document [CN201314862] that tradition uses discloses a kind of mechanical-clamping indexable disc milling cutter, the splicing of the cutting edge of indexable insert tip, throw away tip is used to become one section of molded lines of rotor, but its cutting edge is straightway, the molded lines of rotor precision be therefore spliced into is not high.And blade is difficult to carry out secondary finishing, service life is short.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of cylindrical cutter head wire rod quality of milling edge position-adjustable, the shortcoming that the wire rod quality milling overcoming existing assembling indexable insert tip, throw away tip exists, has long service life, Milling Accuracy is high, chip removal performance is good, the adjustable feature of cutting-edge.
To achieve these goals, the technical solution adopted in the utility model is: a kind of cylindrical cutter head wire rod quality of milling edge position-adjustable, comprises cutter hub, and cutter hub is provided with the different slotted eye in multiple position, is provided with cylindrical cutter head in slotted eye; The upper end of cylindrical cutter head is cutting edge, and lower end is wedge surface; Pressing closer bolt is fixed in slotted eye by the parallel contact faces pressing closer the side of cylindrical cutter head by cylindrical cutter head; Wedge surface closely cooperates with adjustment is top.
Described slotted eye assembles a cylindrical cutter head.
The projection of cutting edge on the axial cross section of wire rod quality of described whole cylindrical cutter head is spliced into the molded line of a tooth of rotor, and cutter head milling part has with a certain distance from cutter hub, is beneficial to chip removal.
Distance 4 ~ the 6mm of the cutting edge distance cutter hub of described cylindrical cutter head.
Described adjustment is top is 7 ~ 8mm with the adjustment stroke of wedge surface.
Compared with prior art, the utility model has following outstanding advantages:
1) common disk milling cutter, on its cutter hub to fill blade be indexable insert tip, throw away tip, blade cut sword is straight line, therefore wire rod quality Milling Rotor, and molded lines of rotor is made up of multistage straight line.Compared to common disk milling cutter, wire rod quality in the utility model assembles the different cylindrical cutter head of multiple cutting edge shape, the cutting edge shape of all cylindrical cutter heads is one section of molded lines of rotor, and the projection of all cutter head cutting edges on the axial cross section of wire rod quality can be spliced into the molded line of a rotor tooth.Therefore after milling, the molded lines of rotor precision of rotor is high.
2) cutting edge of cylindrical cutter head is away from cutter hub, does not need chip pocket, is beneficial to chip removal.
3), after cutting edge wearing and tearing, by regulating the position of cylindrical cutter head to regulate cutting-edge, cut with non-wearing part, to ensure molded line precision.After cutting edge tipping, detachable lower cylindrical cutter head, Linear cut or cutter and tool grinding machine finishing knife head dummy line, and utilize adjusting device positioning cutting sword, molded line precision can be ensured, can only more allowing blade replacement after the wearing and tearing of common disk cutting plate for milling cutters or tipping, therefore the service life of cylindrical cutter head wire rod quality is longer.

Detailed description of the invention
Below in conjunction with accompanying drawing, structural principle of the present utility model and operation principle are described in further detail.
See Fig. 1,2,3,4,5, the utility model comprises cutter hub 1, cylindrical cutter head 2, presses closer bolt 3, regulates top 4, cutter hub 1 there is multiple groove 5 hole, each slotted eye can assemble a cylindrical cutter head 2, during assembling, cylindrical cutter head 2 is put into the slotted eye on cutter hub 1, screw in and regulate top 4, adjust the position of the cutting edge 6 of each cylindrical cutter head 2, make the projection of each cutter head cutting edge molded line on the axial parting face of wire rod quality just in time scrabble up the molded line of a rotor tooth.Screw-in presses closer bolt 3, holding cylindrical cutter head 2 position, and when preventing from cutting, cylindrical cutter head 2 occurs to loosen.When cylindrical cutter head 2 cutting edge weares and teares, unclamp and press closer bolt 3, regulate top 4 positions, unworn part is used to cut, when regulating cutting-edge, cutting-edge is needed to move to cutter hub 1, top 4 then will be regulated to screw out certain distance, gently pressed to cutter hub 1 direction by cylindrical cutter head 2, if desired cutting-edge moves to away from cutter hub 1 direction, then top 4 will be regulated to screw in certain distance, cylindrical cutter head 2 is extruded certain distance, cutting-edge will press closer bolt and screw after regulating and terminating, and when preventing milling, cutter hub is loosening.If when cylindrical cutter head 2 crumbles, pulled down, with cutter and tool grinding machine again reconditioning, then carry out adjustment assembling according to the method described above.
Distance 4 ~ the 6mm of the cutting edge distance cutter hub of described cylindrical cutter head.Chip removal is beneficial to during Milling Rotor.
Cylindrical cutter head is furnished with and regulates the adjusting device of cutting-edge, adjusting device by regulate top, press closer bolt two parts and form.Before adjustment, first unclamp and press closer bolt, the position that rear adjustment is top, if desired cutting-edge moves to cutter hub, then by top back-out certain distance, gently pressed by cutter head to cutter hub direction, if desired cutting-edge moves to away from cutter hub direction, then by top screw-in certain distance, cutter head is ejected certain distance.
