Abstract
The invention relates to a processing method for a spiral bevel gear which applies a CAM software to program an NC program and controls a five shaft link numerical control machine through the NC program to adopt an ordinary milling cutter to finish the rough processing or fine processing on the surface of the spiral bevel gear. The invention can effectively reduce the manufacture cost, shorten the manufacture preparing time, expand the processing range and improve the manufacture efficiency. The invention is in particular suitable for the processing of a big diameter spiral bevel gear.
Description
Technical field
The present invention relates to a kind of processing method of spiral bevel gear, relating in particular to does not a kind ofly need special-purpose Spiral Bevel machine and can improve working (machining) efficiency, reduces manufacturing cost and reduces the processing method of the spiral bevel gear of time.
Background technology
At present, existing spiral bevel gear form of gear tooth has three kinds of Gleasons, Ao Likang, crin shellfish lattice, divides two kinds of equal-depth teeth, tapered tooths in shape.In in enormous quantities, the manufacturing of the spiral bevel gear of small dimension all is to adopt several specific cutterheads to process on special-purpose mill teeth machine at each kind.Therefore though working (machining) efficiency is very high, still there is defective in the processing technology of this existing spiral bevel gear, implements to exist following deficiency using: the one, it is very long to produce time, first drop into very high.For the spiral bevel gear of single and mini-batch production, with the manufacturing process that specific cutterhead is processed on special-purpose mill teeth machine, not only the cutter manufacturing cost is very high, the production cycle long, adjust difficulty, and production speed transition is slow, and the manufacturing cost of part is very high.Not have good plan at present and remove the method, this has brought inconvenience with regard to the manufacturing of giving maintenance of equipment, advanced development and major diameter spiral bevel gear.The 2nd, the restriction of the range of work.The specific cutterhead of existing usefulness is processed the processing technology of spiral bevel gear on the mill teeth machine, because of being subjected to the restriction of machine arrangement form, processing maximum gauge≤2 meter still do not have solution to the spiral bevel gear of larger diameter.The 3rd, special-purpose Spiral Bevel machine complex structure, price is higher, adjusts difficulty, and jobbing work efficient is very low.
Summary of the invention
The technical problem that the present invention solves: at the shortcoming of existing spiral bevel gear processing method, provide a kind of processing method of new spiral bevel gear, can effectively reduce production costs, shorten and produce time, widen the range of work, enhance productivity.Particularly solved the processing difficult problem of major diameter spiral bevel gear.
Mentality of designing of the present invention: in order to solve the manufacturing issue of the single and mini-batch production and the spiral bevel gear of big specification, the present invention uses CAM software programming NC program, can process high-quality spiral bevel gear by cylindrical bar milling cutter and angle scale milling cutter that NC programme-control 5-shaft linkage numerical control machine adopted is common.And the spiral bevel gear of processing has identical tooth surface geometry parameter with adopting the mach spiral bevel gear of mill teeth, guaranteed that equipment and the former design after model machine or the maintenance has homogeneity completely.
Technical solution of the present invention: a kind of processing method of spiral bevel gear, use CAM software programming NC program, finish the roughing or the fine finishining of the spiral bevel gear flank of tooth by NC programme-control 5-shaft linkage numerical control machine adopted plain cutter.
Described 5-shaft linkage numerical control lathe is a 5-axis machining center;
Described 5-shaft linkage numerical control lathe is a digital-control boring-milling machine;
Described plain cutter is a cylindrical bar milling cutter;
Described plain cutter is the plate-like angle milling cutter.
Advantage that the present invention compared with prior art has and effect:
1, produces short, less investment of time.The present invention has greatly shortened the processing preparatory period owing to adopt universal cutter, reduces the first input expense of fourth cutter, has reduced the manufacturing cost of single and mini-batch production and major diameter spiral bevel gear significantly, has shortened the manufacturing cycle.
2, the range of work is wide.The range of work of the present invention is wide, is specially adapted to process the spiral bevel gear of diameter more than 2 meters, for road has been paved in the production domesticization of many jumboes.
3, production efficiency height.The present invention adopts common apparatus and cutter, and equipment is adjusted simple and fast, has improved single and mini-batch production production efficiency greatly.

3, select the spiral shell umbrella semifinishing module of operation, generate semifinishing G code based on the finger-like cutter based on the finger-like cutter.
4, select the spiral shell umbrella fine finishining module of operation, generate fine finishining G code based on the finger-like cutter based on the finger-like cutter.
Utilize the plate-like angle milling cutter to finish the roughing or the fine finishining order of the spiral bevel gear flank of tooth.
1, imports whole parameters of tooth base one by one by drawing, operation tooth base design module, design tooth base.
2, select the spiral shell umbrella roughing module of operation, generate the roughing G code that adopts disk-shaped tool based on disk-shaped tool.
3, select the spiral shell umbrella semifinishing module of operation, generate semifinishing G code based on disk-shaped tool based on disk-shaped tool.
