Description
The invention belongs to the manufacture method of non-involute cutter for gear wheel.
For the non-involute part, as ratchet, sprocket wheel, the processing of special-shaped parts such as spline, harmonic gear, existing general adopt hobboing cutter and broaching tool processing.But can't use the hobboing cutter manufacturing for the axial plane that escape is little, factory is forced to use the energy consumption height, the electrolysis processing that environmental pollution is serious; For the special-shaped cylinder in the blind hole, can't process with broaching tool, can only process with the very high Digit Control Machine Tool of price, if process on slotting machine with the monodentate indexing, not only working (machining) efficiency is low, and crudy is also very poor.
The objective of the invention is to seek the new processing technology of a kind of non-involute part, it adds efficient height, good processing accuracy, save the energy, free from environmental pollution, can solve the processing problems of special-shaped curved surface part, adaptability is strong, and process tool can repeatedly be refaced, and reuses.
The objective of the invention is to realize with the gear shaper cutter for special profile of making all kinds of special-shaped parts of processing.
Gear shaper cutter for special profile manufacturing technology of the present invention comprises two parts:
1, the curved design theory and the method for knife face behind the gear shaper cutter for special profile.
2, the curved surface of knife face approaches economic plunge grinding manufacture method and technology behind the gear shaper cutter for special profile.
The curved design of knife face theory and method (as shown in Figure 1) are behind the gear shaper cutter for special profile: establishing axis of workpiece is OX, and tooth curve is f, and the axis of pinion cutter is Ox.Can be according to conjugation theory in the hope of profile of tooth g, with array g1(X to pinion cutter
I1, Y
I1, Z
I1) expression.But gear shaping needs relief angle, so be taper, after pinion cutter is with blunt refacing, the pinion cutter radius will reduce, and for processing the workpiece of same diameter, both centre-to-centre spacing should be turned down, is calculated the profile of tooth array g2(X in pinion cutter second cross section again by conjugation theory
I2, Y
I2, Z
I2).In like manner, can find with three-dimensional array g(X
Ij, Y
Ij, Z
Ij) expression pinion cutter after the knife face curved surface.From this, pinion cutter is a non-involute profile modified gear.
Behind the gear shaper cutter for special profile curved surface of knife face approach economic form grinding manufacture method and technology as follows: the finishing principle of curve formed grinding wheel is as shown in Figure 2.When diamond pen rotated in the plane by the emery wheel axis, repairing the emery wheel transversal was circular arc, and b, c are center of arc's coordinate parameters in the YOZ plane.If diamond pen is shifted when rotating behind a again, repair the curve M NP that the emery wheel transversal will change for radius of curvature, along with the variation of displacement a and diamond pen radius R, curve shape also will change, can not be greater than 1/3 of grinding wheel radius but move apart from a, otherwise diamond pen can not steady operation; Emery wheel and diamond pen should be constant substantially in the relation in space, but emery wheel will reduce gradually with after blunt, and the machine analysis obtains as calculated, and grinding wheel radius is repaiied in a small amount must not be greater than 1/10 of grinding wheel radius.
Pinion cutter can grind (as shown in the figure) on spline grinding machine.With two the oblique θ of top seat cushion angles, after workbench is shifted to left end, repair formed grinding wheel by grinding wheel arc dresser, move back and forth by workbench then, pinion cutter is worn into the cylinder of bent bus.Regulate shape and position that parameter a, b, c, R, θ can change cylinder, make it theoretical curved surface near pinion cutter.The calculation optimization Mathematical Modeling is
f(a , b , c , R , θ)=
Calculate above-mentioned parameter by computer optimization, adjust circular arc wheel dresser and lathe by this.In approaching calculating, the 1st of pinion cutter profile of tooth should be moved on on the origin of coordinate, the word length of medium-mini computer is just enough, does not influence computational accuracy.In addition, owing to there is systematic error, adjusts trimmer Chang Buneng by calculating parameter and grind satisfied fully profile of tooth.At this moment if profile of tooth curvature brings out existing overgauge greatly, can strengthen and move apart from a; If overgauge appears in the curvature small end, can turn the diamond pen radius R down.
The present invention is owing to adopt gear shaper cutter for special profile processing special-shaped curved surface part, and than electric spark or electrolysis process, its work efficiency improves 3～4 times, and energy-conservation, does not pollute; By computer optimization, the back knife face curved surface that the bent cylinder of easy processing is required near pinion cutter improves 2～3 grades than monodentate calibration craft precision, and profile error is reduced to 10～20 μ m; Adopt the diamond pen displacement of grinding wheel arc dresser, emery wheel is accomplished the curve of different shape, move back and forth by workbench then,, its machining tool can repeatedly be refaced, reuse the cylinder of pinion cutter milled-in curves bus.
The invention will be further described below in conjunction with accompanying drawing:
