Description
Technical field
The invention belongs to precision processing technology fields, and in particular to a kind of cylindrical knife cephalic disc of milling edge position-adjustable
Milling cutter.
Background technology
Helical-lobe compressor has in machinery field to be widely applied very much, and rotor is most important zero of helical-lobe compressor
Part.Spiral camber on screw rotor is formed through helix sweeping by complicated molded lines of rotor, in order to ensure the height of compressor
The requirement on machining accuracy of compression performance, screw rotor is very high.Therefore rational tool sharpening is designed to go out to meet the spiral of precision
Curved surface becomes an important research topic.
At present moulding processing spiral camber milling cutter be mainly wire rod quality, mechanical manufacturing technology to it is efficient, high-precision,
Today of automation development, using Numeric Control Technology as the use of the modern high-precision, high efficiency lathe of representative, to the precision of cutter,
More stringent requirements are proposed for cutting ability, functional reliability etc., and traditional Milling Process Cutting tool is increasingly difficult to adaptive technique innovation,
And indexable tool technology is exactly the cutting-tool engineering that can be matched 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 wire rod quality, the wire rod quality that tradition uses
If patent document [CN201314862] discloses a kind of mechanical-clamping indexable disc milling cutter, spliced using the cutting edge of indexable insert tip, throw away tip
As one section of molded lines of rotor, but its cutting edge is straightway, therefore the molded lines of rotor precision being spliced into is not high.And blade be difficult into
The secondary finishing of row, service life are short.
Invention content
In order to overcome the above-mentioned deficiencies of the prior art, the object of the present invention is to provide a kind of circles of milling edge position-adjustable
Cylindricality cutter head wire rod quality, overcome the wire rod quality milling of existing assembly indexable insert tip, throw away tip there are the shortcomings that, have service life it is long,
Milling Accuracy is high, chip removal performance is good, the adjustable feature of cutting-edge.
To achieve the goals above, the technical solution adopted by the present invention is：A kind of cylinder of milling edge position-adjustable
Cutter head wire rod quality, including cutter hub, cutter hub are equipped with the different slot in multiple positions, cylindrical cutter head are equipped in slot；It is cylindrical
The upper end of cutter head is cutting edge, and lower end is wedge surface；Pressing closer bolt will by pressing closer the parallel contact faces of the side of cylindrical cutter head
Round cutterheads are fixed in slot；Wedge surface and the top tight fit of adjusting.
The slot assembles a cylindrical tool bit.
Projection of the cutting edge of whole cylindrical cutter heads on the axial cross section of wire rod quality is spliced into rotor
The molded line of one tooth with a certain distance from cutter head milling part has from cutter hub, is conducive to chip removal.
Distance 4~6mm of the cutting edge of the cylindrical cutter head apart from cutter hub.
The top adjusting stroke with wedge surface of the adjusting is 7~8mm.
Compared with prior art, the present invention has following outstanding advantages：
1) common wire rod quality, filled blade is indexable insert tip, throw away tip on cutter hub, and blade cut sword is straight line, therefore wire rod quality
Milling Rotor, molded lines of rotor are made of multistage straight line.Compared to common wire rod quality, multiple cut is assembled on the wire rod quality in the present invention
The variform cylindrical cutter head of sword is cut, the cutting edge shape of all cylindrical cutter heads is one section of molded lines of rotor, and all cutter heads are cut
Cut the molded line that projection of the sword on the axial cross section of wire rod quality can be spliced into one tooth of rotor.Therefore after milling rotor rotor-type
Line precision is high.
2) cutting edge of cylindrical cutter head is not required to chip pocket far from cutter hub, is conducive to chip removal.
3) after cutting edge abrasion, cutting-edge can be adjusted by adjusting the position of cylindrical cutter head, with non-wear
Divide and cut, to ensure molded line precision.After cutting edge tipping, cylindrical cutter head, wire cutting or cutter and tool grinding machine is detachably descended to repair
Whole cutter head molded line, and position cutting edge using regulating device, you can ensure molded line precision, the abrasion of common disk cutting plate for milling cutters or tipping
After can only more allowing blade replacement, therefore the service life of cylindrical cutter head wire rod quality wants longer.

Specific implementation mode
Xia Mianjiehefutuduibenfamingjiegouyuanlihegongzuoyuanlizuojinyibuxiangxishuoming.
Referring to Fig. 1,2,3,4,5, the present invention includes cutter hub 1, cylindrical cutter head 2, presses closer bolt 3, adjusts top 4, cutter hub 1
On have multiple slots 5, each slot 5 can assemble a cylindrical cutter head 2, and when assembly, cylindrical cutter head 2 is put on cutter hub 1
Slot 5 in, screw in adjust top 4, adjust the position of the cutting edge 6 of each cylindrical cutter head 2, make each cutter head cutting edge molded line
Projection in wire rod quality axial direction parting face just scrabbles up the molded line of one tooth of rotor.Screw-in presses closer bolt 3, fixed cylinder shape
2 position of cutter head prevents cylindrical cutter head 2 when cutting from loosening.When 2 cutting edge of cylindrical cutter head is worn, release presses closer spiral shell
Bolt 3 is adjusted top 4 position, is cut using unworn part, when adjusting cutting-edge, needs cutting edge position
It sets to cutter hub 1 and moves, then will adjust top 4 and screw out certain distance, cylindrical cutter head 2 is gently pressed to 1 direction of cutter hub, is if desired cut
It cuts sword position to move to far from 1 direction of cutter hub, then will adjust top 4 and screw in certain distance, cylindrical cutter head 2 is squeezed out into a spacing
After being adjusted from, cutting-edge, bolt will be pressed closer and screwed, prevents cutter hub when milling from loosening.If cylindrical cutter head 2 collapses
Bad when, is removed, and with cutter and tool grinding machine again reconditioning, assembly is then adjusted according to the method described above.
Distance 4~6mm of the cutting edge of the cylindrical cutter head apart from cutter hub.It is conducive to chip removal when Milling Rotor.
For cylindrical cutter head equipped with the regulating device for adjusting cutting-edge, regulating device is top by adjusting, presses closer bolt two
Part is constituted.Before adjusting, first unclamps and press closer bolt, adjust top position afterwards, if desired cutting-edge is moved to cutter hub, then
By top back-out certain distance, cutter head is gently pressed to cutter hub direction, if desired cutting-edge is moved to far from cutter hub direction, then
By top screw-in certain distance, cutter head is ejected into certain distance.
