Description
【Technical field】
The utility model belongs to machine tools field, and in particular to a kind of axial feed shaving knife for being used to process gear.
【Background technology】
The suface processing quality of gear influences gear-driven stationarity, noise when surface quality difference will cause the gear to engage
Greatly, product quality is had a strong impact on.One of the main reason for shaving plucking is gear surface low precision, shaving plucking not only influence to produce
Quality, while the gear shaver life-span can be reduced, the current razor single sharpening life-span is only 250 or so, adds production cost.
Shaving is one kind of gear finishing process, and shaving surface accuracy has directly to the final suface processing quality of gear
Connect influence.Shaving plucking refers to the line shape squama thorn formed after shave on gear teeth face.The process of shaving includes gear shaver and tooth
Take turns between the flank of tooth caused sliding motion and by reciprocating motion of the shaving wheel along its axis direction, gear shaver during gear shaver processing gear
Make spatially spiral gear with being cut gear to be staggered open top container ship, and driven by gear shaver and rotated by shaving wheel, this
Individual process is extremely complex.Because when gear shaver engages with gear to be cut, the sliding velocity of flank profil is zero at middle pitch circle, tooth top
Maximum with the sliding velocity at tooth root, in axial feed, the cutting locus of points mainly remains in the flank of tooth in the form of surface roughness
At tooth top and tooth root, so, the tooth top and tooth root of the flank of tooth are the regions of most easy plucking.
Influence shaving surface roughness factor also have several factors, as machine tool accuracy, blank quality, construction de-sign,
Cutting data etc..Wherein, if the shaving tool time limit is long, its precision it is difficult to ensure that, vibration can be caused in Shaving Process, is made
Into the processed flank of tooth " gnawing tooth " phenomenon, namely shaving plucking.And workpiece material hardness is improper that gear shaver can be made to collapse tooth or in knife
Sharp place forms built-up edge, causes shaving flank of tooth plucking.In view of the requirement of production efficiency, cutting data can not be too low, and feeds
Amount conference widens knife mark, surface roughness is deteriorated.And it is smaller to improve space because its service life is more long for machine tool accuracy.Work
Part material hardness different batches differ greatly, it is more difficult to control.So can only solve shaving plucking from the structure optimization of gear shaver
Problem.But it is less on solving the research of shaving plucking this respect by optimizing razor design in domestic and foreign literature at present,
Feasible solution method there is no may be referred to.
【Utility model content】
The purpose of this utility model is to eliminate the deficiencies in the prior art, there is provided a kind of nonstandard big chip pocket axial feed shaving
Knife, the gear shaver have taken into account the cutting edge number of chip removal ability and razor, have effectively improved the surface quality of workpiece shaving, make up
The defects of machine tool accuracy, workpiece material hardness, solves the problems, such as shaving plucking.
The utility model uses following technical scheme：
It is a kind of to be used to process the axial feed shaving knife of gear, angularly it is uniformly arranged some shave on the periphery of the gear shaver
Tooth, two end faces of gear shaver are plane, and multiple cutting edges and chip pocket, the tooth pitch of the chip pocket are arranged at intervals with shaving
P is 2.05~2.25mm, and the width of chip pocket is 1.25~1.45mm, and cutting edge width b is 0.8mm.
The width of chip pocket described further is preferably 1.3mm.
The tooth pitch p of chip pocket described further is preferably 2.1mm.
The height h of chip pocket described further is 0.9~1.1mm.
The height h of chip pocket described further is preferably 0.95mm.
The width of the further gear shaver is 25mm.
Compared with prior art, the utility model at least has the advantages that：
The utility model discloses a kind of axial feed shaving knife for being used to process gear, by changing chip pocket on gear shaver
Width and tooth pitch P, improve chip removal ability, improve the surface quality of gear, while two side walls of former gear shaver are convex
Platform part is removed, and the real work facewidth is increased in the case where gear shaver overall width is constant, takes into account number and the row of cutting edge
Consider space to be worth doing, solve the problems, such as shaving surface galling.Next greatly improves the service life of gear shaver, reduces more tool changing
Have the frequency, improve operating efficiency, also reduce the cost of charp tool in addition.

【Embodiment】
The purpose of this utility model is elimination the deficiencies in the prior art, and the utility model is using change gear shaver chip pocket
The technical scheme of structure, increase the width of chip pocket, improve chip removal ability, solve the problems, such as shaving plucking.
The utility model is described in further detail below in conjunction with the accompanying drawings.
Refer to shown in Fig. 2-5, the utility model discloses a kind of axial feed shaving knife for being used to process gear, the gear shaver
Periphery on angularly divide equally be provided with multiple shavings, multiple cutting edges and chip pocket are arranged at intervals on each shaving, cut
Sword is used to carry out machining to workpiece, and the waste iron filing that cutting edge machines away is discharged into chip pocket, with turning for axial feed shaving knife
Dynamic, waste iron filing excludes from chip pocket；Two end faces of gear shaver are the plane being parallel to each other, the centrally disposed installation of gear shaver
Hole, keyway is provided with mounting hole, it is circumferentially positioned for being carried out to gear shaver；The wherein tooth pitch P of chip pocket be 2.05~
2.25mm, the width of chip pocket is 1.25~1.45mm, and the height h of chip pocket is 0.9~1mm, and the width b of cutting edge is
0.8mm, the overall width of gear shaver use state's dimensioning.
Embodiment 1
It is a kind of to be used to process the axial feed shaving knife of gear, angularly divide equally on the periphery of the gear shaver and be provided with multiple shave
Tooth, multiple cutting edges and chip pocket is arranged at intervals on each shaving, two end faces being parallel to each other of gear shaver are plane；Chip pocket
Tooth pitch P be 2.1mm, the width of chip pocket is 1.3mm, and the height h of chip pocket is 0.95mm, and the width b of cutting edge is
0.8mm, the overall width of gear shaver is 25.
Embodiment 2
It is a kind of to be used to process the axial feed shaving knife of gear, angularly divide equally on the periphery of the gear shaver and be provided with multiple shave
Tooth, multiple cutting edges and chip pocket are arranged at intervals on each shaving；The tooth pitch P of chip pocket is 2.05mm, and the width of chip pocket is
1.25mm, the height h of chip pocket is 1mm, and the width b of cutting edge is 0.8mm, and the overall width of gear shaver is 25.
Embodiment 3
It is a kind of to be used to process the axial feed shaving knife of gear, angularly divide equally on the periphery of the gear shaver and be provided with multiple shave
Tooth, multiple cutting edges and chip pocket are arranged at intervals on each shaving；The tooth pitch P of chip pocket is 2.25mm, and the width of chip pocket is
1.45mm, the height h of chip pocket is 0.9mm, and the width b of cutting edge is 0.8mm, and the overall width of gear shaver is 25.
It is the procedure of processing of gear shaver below：
1st, checked before cutter being installed.Ensuring two top centres of gear shaving machine does not have workpiece.
The 2nd, gear shaver is installed.Select the edge bearing of Rational Thickness, it is ensured that gear shaver width center line and saddle rotation center superposition.
And with percentage table look-up installation accuracy, the circular runout and end face run-out for ensureing gear shaver are respectively less than 0.01mm.
