Abstract
The present invention relates to a kind of corrugated edge spiral cutter and processing method thereof.The main points of this milling cutter are that it has the waveform sword of a radial dimension unanimity at least, and this milling cutter is than the high 3-5 of plain cutter stock-removing efficiency times, and it is good to be cut surface roughness.Processing method provided by the present invention is simple, only need on plain-milling machine, former milling cutter processing helicla flute change gear than constant situation under, in change gear train, increase a pair of non-circular gear, rotate thereby make milling cutter to be processed produce periodic speed change, and reach the purpose of milling ripple.During knife face, support plate props up in waveform groove or former roller seating space place behind the sharpening.
Description
The present invention relates to a kind of corrugated edge spiral cutter and processing method thereof.
Once introduced a kind of method processing waveform blade milling cutter that utilizes swing milling machine bed surface in 1978 the 8th phases " mechanic " " cold processing technique data ".It is big to use this method lathe to change, therefore, complex structure, investment is big.In addition, inconsistent with the milling cutter land radial dimension that the method for its introduction processes, promptly the radial dimension at waveform sword crest place is greater than the radial dimension at trough place, and is relatively poor with the workpiece surface roughness that this milling cutter processes.
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art part, and the method that provides a kind of waveform sword can process the inconsistent screw-on cutter of waveform sword at the crest corrugated edge spiral cutter identical with trough place radial dimension and a kind of screw-on cutter that simply can process waveform sword radial dimension unanimity.
The objective of the invention is to realize: the helicla flute that at first on plain-milling machine, processes milling cutter by following measure, then change gear than constant situation under, in change gear train, increase a pair of non-circular gear, elliptic gear particularly, change gear is than producing cyclically-varying, thereby be directed at milling cutter to be processed and produce periodic speed change rotation, and the motion of bed surface still can process waveform for movement at the uniform velocity along the spiral rake face of milling cutter to be processed with cutlery or the grinding tool that the end is the arcuation sword, when behind the sharpening during knife face, if support plate is supported on waveform troughed belt place, the back knife face that then is ground is the curved surface that changes with synchronous waveform, so the milling cutter of making is the milling cutter of waveform sword radial dimension unanimity.If support plate is supported on former roller seating space place, the milling cutter of then making is the inconsistent milling cutter of waveform sword radial dimension.
The screw-on cutter of waveform sword radial dimension unanimity provided by the present invention is compared with plain cutter, can improve stock-removing efficiency 3-5 doubly, and processed workpiece surface roughness is better.Method provided by the present invention is simple, and only needing to increase in the change gear train of plain-milling machine a pair of non-circular gear can realize.
Below in conjunction with accompanying drawing the present invention is further described:
Fig. 1 is the transmission schematic diagram along milling cutter spiral rake face processing ripple.
Fig. 2 is the schematic diagram that support plate is supported in waveform groove.
Fig. 3 is the profile of the A-A of Fig. 2.
With reference to Fig. 1, the change gear of the gear changing group that gear 2,3,6,7 is formed than with former milling cutter processing spiral fluted change gear than equating, in this gear changing group, increased a pair of elliptic gear 4,5.When processing waveform on the spiral rake face at milling cutter 9, bed surface leading screw 1 is done uniform rotation, and promptly bed surface 10 is done vertically at the uniform velocity mobile.When elliptic gear 4,5 rotated a week, the side shaft 8 of dividing head 11 was promptly made once periodic speed change and is rotated, and therefore, milling cutter 9 is also made a second periodicity speed change by drive and rotated, and at this moment, cutlery and grinding tool 12 promptly process the waveform of a pitch of waves along the spiral rake face.Because elliptic gear 4,5 is coaxial with gear 3, therefore, the gear ratio of gear 2 and gear 3 directly influences the size of milling cutter 9 axial wave distances, and the pitch because of leading screw 1 is fixed number again, so,
Axial wave distance=(number of teeth of the pitch * gear 3 of leading screw 1)/(number of teeth of gear 2) of milling cutter waveform
Determine the number of teeth of gear 2 and gear 3 according to the pitch of waves after, determine the number of teeth of gear 6 and gear 7 again according to the number of teeth of gear 2 and gear 3, that is:
(number of teeth of the number of teeth * gear 6 of gear 2)/(number of teeth of the number of teeth * gear 7 of gear 3)=former processing spiral fluted change gear ratio
With reference to Fig. 2, support plate 13 is supported in waveform groove 14 places of the spiral rake face of milling cutter 9, then behind the sharpening during knife face 15, can guarantee that its waveform sword radial dimension is consistent everywhere.
With reference to Fig. 3, shown in it is to be with the cutter tooth 16 of waveform sword with the cutter tooth 17 with the waveform sword is not alternate.
Corrugated edge spiral cutter can be according to processing object and user's needs, when manufacturing, make the sword tooth and all be waveform sword or part tooth and be the waveform sword and another part tooth is common sword, and the size of the pitch of waves, the position of each waveform sword crest and trough etc.In addition, processing is during ripple, and the available slotting cutter or the cotter mill cutter transformation of the way are made the circular arc sword with the bottom, and also available formed grinding wheel processing etc. that is to say that waveform can directly mill out, after also can milling again grinding once perhaps directly grind waveform.
