Description

Toolholder of adjustable strip cutter blade machine
The utility model mechanical clamp cutting tool for adjustable strip-shaped cutter blade relates to metal-cutting machine tool.
The anterior angle mechanically-clamped turning tool of deciding of existing employing strip insert design is to determine the horizontal established angle of blade in advance according to concrete processing conditions, and, calculate lathe tool cutting edge inclination, cutter groove and Sharpening a knife blade and derive from the angle by selected lathe tool anterior angle, major and minor drift angle, major and minor relief angle.This cutter groove, when the blade clamping after on the knife bar, could obtain a kind of selected lathe tool angle.And existing strip blade is because of being subjected to the influence of horizontal established angle, not only cutter head is roomy, the rational anterior angle of lathe tool can't be met, the blade clamping is not firm, in actual production, both should not process small diameter workpiece, more can not process large-diameter workpiece or carry out big cutting data processing, also want the operator that blade is left chip-breaker, the service life and the cutting ability of blade had both been influenced, increased working strength of workers again, and cutter chip breaking effect is also bad, the utilization rate of blade is about 30%, therefore, be difficult to apply.
And for example once be used as throw away (indexable) cutter that China's new technology emphasis is promoted, also cause the blade utilization rate low excessively because of the restriction that is subjected to its blade, cutter hub self structure, chip breaking range is narrower, and the influence of factor such as regrinding blade condition is overcritical, make applying of it also very difficult, so up to now, almost the carbide-tipped lathe tool that most lathe adopted also rests on the level of welded type lathe tool.
The purpose of this utility model is to provide a kind of blade utilization rate higher in order to overcome weak point of the prior art to society, cut brisk, the chip removal smoothness, chip breaking (volume bits) is reliable, operate simple and easy, versatility is good, cutter structure compactness, the mechanical clamp cutting tool for adjustable strip-shaped cutter blade that consumption costs can descend at double.
The technical solution of the utility model is achieved in that the design principle of mechanical clamp cutting tool for adjustable strip-shaped cutter blade is according to the relation between this three covers angle of mechanically-clamped turning tool, cutter groove geometric parameter and blade angle lap, with the cutter angle of the v-groove γ of adjustable strip-shaped blade mechanically-clamped turning tool PgAnd γ FgElect definite value as, in addition, lathe tool tool cutting edge angle K r, auxiliary angle K r', primary clearance α O, front clearance α O' pre-determine according to processing request, and γ PgP, γ Fgf, so the known angle of this lathe tool is: γ p, γ f, K r, K r', α O, α O'.According to the γ in the known lathe tool angle p, γ f, K rCan try to achieve the anterior angle γ of lathe tool OWith cutting edge inclination λ SBecause the lathe tool angle is the Sharpening a knife blade angle and derivation angle after the cutter angle of the v-groove combines, so, for the major and minor drift angle that makes blade and major and minor relief angle after being installed to the cutter groove, can satisfy the known conditions K in the lathe tool angle r, K r', α O, α O' requirement, also to calculate Sharpening a knife blade angle tool cutting edge angle K Rt, auxiliary angle K Rt', primary clearance α Ot, front clearance α Ot'.In sum, the angle of finding the solution is: r O, λ S, K Rt, K Rt', α Ot, α Ot'.Try to achieve by relevant formula and formula conversion.
Mechanical clamp cutting tool for adjustable strip-shaped cutter blade is made of knife bar, blade, pad, shred holding up plate, housing screw, locating piece, adjustment screw rod.Knife bar one side longitudinally has a cutter groove that runs through, in order to the overlapping shred holding up plate of clamping, blade, pad, have parallel with the cutter groove and open and the cutter groove is divided into upper and lower two-part elastic groove at the another side of cutter groove first half, the clamping force of lathe tool blade obtains by the knife bar strain.
Blade is not open the strip blade of chip-breaker, existing major and minor drift angle and major and minor relief angle, blade anterior angle γ Ot=0 °, cutting edge inclination λ St=0 °, and upper and lower faces is parallel, as cutter angle of the v-groove γ PgAnd γ FgAnd lathe tool angle K r, K r', α O, α O' after determining, can calculate lathe tool angle γ OAnd λ SAnd Sharpening a knife blade angle K Rt, K Rt', α Ot, α Ot'.These blade angle can unload blade the back sharpening, also can be contained in sharpening on the knife bar.Blade behind the sharpening reaches the purpose that point of a knife resets by adjusting screw rod in the cutter groove, connect the locating piece of adjusting screw rod and be fixed in the cutter groove.Cut processing conditions according to different gold,, can obtain reasonably lathe tool anterior angle and cutting edge inclination by changing the tool cutting edge angle and the primary clearance of blade.
Shred holding up plate that blade is upper and lower and pad not only can be protected the cutter groove, also are convenient to adjust the gap of blade in the cutter groove.According to different processing conditions, the shred holding up plate front end is worn into and can be formed the different groove widths and the chip-breaker of flute profile with blade front master's sword, can obtain good chip breaking (volume bits) effect.
Anterior angle of this mechanically-clamped turning tool and cutting edge inclination are the derivation angle of Sharpening a knife blade angle clamping after in the cutter groove.After the decision of the cutter angle of the v-groove, the size of blade tool cutting edge angle is the unique parameter that influences mechanically-clamped turning tool anterior angle and cutting edge inclination.If with cutter groove tool cutting edge angle is that 60 ° knife bar is as general knife bar, can change the size (45 °~75 °) of sharpening sheet tool cutting edge angle according to concrete processing situation, thereby lathe tool anterior angle and cutting edge inclination that acquisition and tool cutting edge angle adapt are to satisfy the needs of multiple processing conditions.
According to the blade localization method of this mechanical clamped cutting tool and the structure of refacing,, also can make machine folder cylindrical offset tool and the mechanically-clamped turning tool for external threading and the various left cutter of about 90 ° of tool cutting edge angles by changing insert shape and knife bar flute profile.
According to the mechanical clamp cutting tool for adjustable strip-shaped cutter blade of the utility model design, can regulate the blade point of a knife and reset; Can change the tool cutting edge angle and the primary clearance of blade according to different processing conditions, the anterior angle of palpus lathe tool and cutting edge inclination to reach; Can also be by regulating or the reconditioning shred holding up plate, obtain multiple flute profile and groove width, to obtain good chip breaking or volume bits effect, and blade is not subjected to sharpening and influences service life, the Tool in Cutting performance is good, and the operator is easy to adjust, uses flexibly, not only can process small diameter workpiece but also can process large-diameter workpiece (as the roughing of 100 millimeters of φ) and big consumption cutting, the blade utilization rate can reach about 70%.This straight tool of end milling cutter also has the high characteristics of general degree, with a tool cutting edge angle is that 60 ° knife bar is as general knife bar, as long as by changing sharpening sheet major flank and tool cutting edge angle, just can make straight tool of end milling cutter obtain reasonably anterior angle and cutting edge inclination, have the function of multi-use.
