detailed description of the invention:
For making object of the present invention, technical scheme clearly understands, is described further installation method of the present invention below in conjunction with accompanying drawing specific embodiment.
See Fig. 1-Figure 10, a kind of complex function of the present invention indexable tool is made up of a special curved surface triangle tool section 21 and the knife bar 1 coincide with this tool section shape and the pressing plate 4 coincide with this tool section shape and fastening screw 3.This tool section 21 is positioned between knife bar 1 and pressing plate 4, to be connected on the fastening screw screw 27 on knife bar 1, tool section 21 and pressing plate 4 to be fastened on knife bar 1 by fastening screw 3 by the screw vent 28 on pressing plate., on the boss 2 at position, knife bar front end, there is pressing plate seat plane 5 position of pressing plate, and pressing plate seat plane both sides to have after pressing plate groove side 12 and pressing plate groove 13 for the stressed location of pressing plate, pressing plate front end face have technique fillet surface 14, just attractive in appearance for economizing material.
It is equilateral triangle position distribution that overall tool section 21 locates profile curvilinear plane, each face has tool section to cut primary clearance α 2 and tool section chip curling groove 16, three R2 circular arcs are 120 ° of equal distribution on tool section triangle section, when a certain circular arc bears cutting volume bits task, another two circular arcs bear location tasks on knife bar tool section composition surface 10.Whole tool section compresses location by three knife bar tool section composition surfaces 10 of knife bar cutter groove below and the pressing plate cutter head composition surface 6 of pressing plate 4 above, circular arc R 1 on pressing plate is tangent in circular arc with chip curling groove on tool section 16, and the bits of workpiece successively flow to tool section chip curling groove 16 and pressing plate chip curling groove 15 along main cutting edge 18.In order to protect blade 18 on tool section 21 and point of a knife 20, in knife bar tool section locating slot and pressing plate tool section stopper slot, all have a point of a knife protection groove 22 and pressing plate fastening procedure groove 7, in case the blade damaged by pressure on tool section and be convenient to fastening tool section.When tool section 21 be arranged in knife bar tool rest in a negative side rake λ compacted after, a front clearance α 1 is just defined between its tool section minor flank 9 and tool minor cutting edge plane, and consistent with knife bar minor flank 11 angle of knife bar 1, main cutting edge 18 and the front cutting edge 8 of tool section 21 have tool cutting edge angle on basal plane
and auxiliary angle
.The major flank 17 of tool section 21 is consistent with the angle of the major flank 19 of knife bar 1.In order to strengthen the intensity of point of a knife 20, the main cutting edge of tool section 21 is provided with horizontal corner angle 25 and chamfered edge 26, point of a knife 21 circular arc portion is provided with transitional edges 23 and wiper edges 24, to improve the quality of work piece surface, its length L 1 and L 2 can design according to processed materials and process, and L 3 and L4 also can be designed to arc transition.
When machining, when after the first corner wear, only need unclamp fastening screw 3, lift pressing plate 4, tool section 21 is rotated a face, again fastening for tool section second point of a knife that just can utilize is carried out second time processing, when after the second corner wear, unclamp according to above method again, fastening rear use the 3rd point of a knife carries out third time processing, after the 3rd point of a knife also weares and teares, just as Suo Shi 30 of Figure 10, tool section can be stretched out forward, then fastening sharpening, during sharpening, tool section minor flank plane is kept vertical with the plane of major flank, again tool section good for institute's sharpening is reinstalled after sharpening to fix and namely again can carry out indexable cyclic process.
Tool section of the present invention each time can transposition three times after sharpening, and sharpening amount is only 0.1-0.3mm under normal circumstances, at most can not more than 0.5mm, calculate with the land length of normal indexable insert tip, throw away tip 20mm, under the auxiliary clamping of auxiliary fastening tool section 29 as shown in Figure 9, the service life of tool section can be extended to about 5mm, calculate with the amount of mill 0.5mm at most from 20mm to 5mm and can reface 30 times, indexable use three times after at every turn refacing, actual access times reach 90 times, are 30 times of common indexable insert tip, throw away tip with indexable number of times calculating; Calculate than the many use of traditional mechanical clamped cutting tool 60 times with the amount of mill equally and material, tool section utilization rate is 3 times of mechanical clamped cutting tool; Calculate than the many use of traditional welding blade 120 times with the amount of mill equally and material, tool section utilization rate is 4 times of brazed carbide turning tool.
With reference to Figure 11-Figure 14, the installation method of a kind of complex function indexable tool of the present invention can be widely used in the cylindrical turning in turnery processing field, facing and endoporus turning, and tool section of the present invention and installation method thereof can also be used for Milling Process field simultaneously.
With reference to Figure 15-Figure 26, above-mentioned enforcement billmpse tool case is only the preferred embodiments of the invention, and the tool section design ap-plication type of this cutter can be billmpse tool, facing tool, internal lathe-tool and milling cutter.It should be pointed out that for the person of ordinary skill of the art, under the premise without departing from the principles of the invention, can make some equivalents to the design shape of tool section within the scope of polygon, these equivalents all should be considered as protection scope of the present invention.
Tool section material is equally also be chosen as Hardmetal materials according to the preferred version in turnery processing field, in like manner also can according to rapidoprint and technique need select high speed steel material or other materials.
The installation method of a kind of complex function indexable tool of the present invention can be widely used in machine-building metal cold manufacture field, at province's material, saves time, can reduce production cost in the situation of labour-saving, enhance productivity.
