Description
Technical field
This utility model relates to a kind of metal cutting tool, a kind of cut the gear shaper without theoretical profile error straight-tooth of tooth processing to pieces for helical gears and cuts serrated knife to pieces.
Background technology
Still it is in conceptual phase currently, with respect to cutting the design of serrated knife lamps structure to pieces, there is no the cutter structure scheme of maturation.Abroad the research and development situation cutting serrated knife structure to pieces is holded in close confidence, can look into without reference to document.Domestic cut serrated knife structure to pieces based on the design of pinion cutter design theory, and need to propose roller gear single-side edge for processing and Double-side edge cuts tooth Tool Design structure to pieces.This kind of cutter rake face is the conical surface, and rear knife face is involute helicoid.Such cutter structure causes the part processed to there is bigger theoretical profile error, it is difficult to meets and cuts tooth processing needs to pieces.
Summary of the invention
In order to solve above-mentioned technical problem, this utility model provides a kind of gear shaper without theoretical profile error straight-tooth to cut serrated knife to pieces.Using sphere as rake face, tool strength is high；The curved surface that the main sword using repeatedly rake face to intercept conjugate tooth surface construction is constituted, as knife face after master, can increase substantially machining accuracy.
This utility model solves technical problem and be the technical scheme is that a kind of gear shaper without theoretical profile error straight-tooth of research cuts serrated knife to pieces, it is characterized in that: it is gear type cutter that gear shaper without theoretical profile error straight-tooth cuts serrated knife to pieces, its structure is to be provided with one week cutter tooth on the external cylindrical surface of a cylindrical cutterhead, each cutter tooth includes rake face, knife face behind top, knife face after master, main sword and top sword, rear end face at cutterhead is provided with disc boss, the through conical bore for connecting is had with knife bar at the center of cutterhead and boss, described rake face is positioned at the front end face of cutterhead, rake face is centre of sphere sphere on cutter axis, behind described top, knife face is positioned at the tooth top of cutter tooth, behind top, knife face is vertex of a cone taper seat on cutter axis, after described master, knife face is positioned at two sides of cutter tooth, it it is the curved surface that disclosure satisfy that gear shaper without theoretical profile error processing request；Described main sword be described rake face with main after the intersection of knife face；Described top sword be described rake face with top after the intersection of knife face.
The beneficial effects of the utility model are: using sphere as rake face, tool strength is high；The curved surface that the main sword using repeatedly rake face to intercept conjugate tooth surface construction is constituted, as knife face after master, can increase substantially machining accuracy；With design based on pinion cutter design theory cut serrated knife to pieces compared with, this utility model has bigger forward and backward angle, can improve and cut tooth machining condition to pieces.

1 rake face in figure, 2 top swords, 3 main swords, knife face after 4 masters, knife face behind 5 tops, 6 cutters tooth, 7 boss, 8 cutterheads, 9 conjugation wheels.
Detailed description of the invention
As shown in Figures 1 and 2, this utility model is gear type cutter, and its structure is to be provided with one week cutter tooth 6 on the external cylindrical surface of a cylindrical cutterhead 8, each cutter tooth 6 include knife face 5 behind rake face 1, top, main after knife face 4, main sword 3 and top sword 2；Rear end face at cutterhead 8 is provided with disc boss 7, the through conical bore for connecting is had with knife bar at the center of cutterhead 8 and boss 7, having the groove for driving cutter on boss 7, rake face 1 is positioned at the front end face of cutterhead 8, and rake face 1 is centre of sphere sphere on cutterhead 8 axis；Behind top, knife face 5 is vertex of a cone taper seat on cutterhead 8 axis；After master, knife face 4 is the side of cutter tooth, is the curved surface that disclosure satisfy that gear shaper without theoretical profile error processing request；Main sword 3 be rake face 1 with main after the intersection of knife face 4；Top sword 2 be rake face 1 with top after the intersection of knife face 5.
With design based on pinion cutter method for designing cut serrated knife to pieces compared with, in present embodiment, cutter meets gear shaper without theoretical profile error and cuts tooth processing request to pieces.As shown in Figure 3, it is assumed that have a straight spur gear to engage with part to be processed, conjugation wheel 9 it is called.According to space curved surface conjugate principle, if main sword 3 is in and just can form gear shaper without theoretical profile error on conjugation wheel 9 flank of tooth and cut the cutter structure of tooth processing to pieces.Main sword 3 is the intersection of conjugation wheel 9 and rake face 1.Owing to behind top, knife face 5 is taper seat, it is gradually reduced to vertex of a cone direction, radius of addendum from cutterhead 8 front end.According to the normal meshing condition of gear, conjugation wheel 9 is carried out displacement process, form a new conjugation wheel 9.New conjugation wheel 9 is crossed to form a new main sword with rake face 1；The rest may be inferred, forms many main swords of bar 3.Shrink to the vertex of a cone direction of knife face 5 behind top, knife face 4 after the master that disclosure satisfy that gear shaper without theoretical profile error processing request it is made up of from cutter front end these main swords 3.In sum, content of the present utility model is not limited in above-described embodiment, and those skilled in the art can propose other embodiment easily according to guiding theory of the present utility model, and these embodiments are included within the scope of this utility model.
Specific process is, as shown in Figure 3, the axis of the axis of cutterhead 8 and conjugation wheel 9 is installed at an angle, cutting tooth machine to pieces drives cutterhead 8 and conjugation wheel 9 to rotate by a certain percentage, top sword 2 and main sword 3 are relative to conjugation wheel 9 generation relative motion, each top sword 2 and main sword 3 and conjugation wheel 9 are engaged to exit engagement by entrance and complete cutting at one time, and chip is by thin thickening more thinning by thickness.Along with the not stall of cutterhead 8 and conjugation wheel 9 is moved, top sword 2 and main sword 3 have just carried out the cutting of the complete cycle gear teeth to conjugation wheel 9, cutterhead 8 is feeding the most vertically while rotating, it is achieved thereby that with the cutting to conjugation wheel 9 whole gear teeth length directions, after cutting one layer, axially withdrawn cutterhead 8, by cutterhead 8 radially feeding certain depth, repeat the above-mentioned course of processing, until all machining.
