Specific embodiment
The present invention is described in further detail with reference to the accompanying drawing.
The nonstandard outer circle indexable turning tool of 90 ° of straight peens of a kind of C blade of the invention, mainly there is cutter hub, blade, edge bearing, bias
Pin, pressure head composition.Key is the following aspects.
1) structure of the cutter body formed by Stress calculation and processing experiment.
2) centering type blade clamping structure.
3) lathe process stretches out the method for platform inner groovy.
Particular content is as follows: 1) structure of the cutter body formed by Stress calculation and processing experiment: according to cutting depth ap=
10mm, amount of feeding f=0.6mm/r, cutting speed v=110m/min obtain 14 ° of lathe tool angle anterior angle, 6 ° of relief angle, tool cutting edge angle
90 °, -6 ° of cutting edge inclination.And according to 80 ° of diamond type blades (standard component) of lathe tool angle Selection, and according to active length needs, calculate
Blade d1 > 4.5248, S >=4.8, r=1.2 out.Therefore selection CNUM160608-H4 model blade, having a size of blade side length L=
16.1mm, (blade) inscribed circle diameter d=15.875, blade thickness S=6.35, (blade) fixed hole diameter d1=6.35, knife
The circularity r=0.8 of sharp fillet, the long side m1=3.97 of position of tool tip size, position of tool tip size short side m2=2.182.Knife
Piece parameter: 80 ° of rough turn nose angle, 0 ° of cutting edge inclination, 7 ° of tool nomal clearance, 20 ° of method anterior angle, chip-breaker width 4mm.And according to above-mentioned size
The edge bearing of model C16B is selected.According to 90 °, -6 ° of cutting edge inclination of cutter hub tool cutting edge angle, can be calculated -6 ° of cutter hub anterior angle, after
6 ° of angle, 9.5 ° of auxiliary angle, 5 ° of front clearance.No. 45 steel are selected, optimal use can be guaranteed by being heat-treated to HRC38-45 by test
Effect.In conjunction with part actual size, cutter hub overhang (distance of point width knife handle) 13mm, 15mm, 20mm, 25mm is designed.It is logical
Overtesting discovery, when cutter hub extends forward 15mm, processing can both guarantee not influencing chip removal and guarantee cutter hub service life, make
Best with effect, the cost of charp tool is minimum.
2) centering type blade steps up structure: processing is on CA6140 center lathe or CKA6150 centre numerically controlled lathe
It carries out, it is contemplated that for the progress for guaranteeing production continuous cutting, lathe tool steps up structure and steps up to tie using better simply centering type blade
Structure.Blade is fixed on cutter hub by design cam pin and pressure head, and cam pin selects 40Cr, heat treatment hardness HRC40-45, eccentric
Pin design bias 0.5mm, can be such that blade steps up reliably, and can guarantee not influencing the chip removal in process, will not make
Decline at lathe tool service life.
3) lathe process stretches out the method for platform inner groovy: stretching out on front side of cutter hub by way of cutter head, guaranteeing lathe tool and zero
There are enough gaps among part: neither will lead to remaining position that high-speed rotating part encounters lathe tool, and guarantee lathe tool
Gap between cutter hub and part meets the needs of chip removal.Simultaneously enough cutting stress are provided, guarantee cutting the amount of feeding with into
To speed.Accomplish for multi-diameter shaft, the complex structural members such as crank arm to be processed and formed at one time by standard machinery or numerically controlled lathe.
