Abstract
The invention provides a turning method of a right-angle triangular pyramid. The method comprises the steps of: firstly, preparing a refined cube from a blank material, then automatically producing an auxiliary fixture, wherein the auxiliary fixture comprises a chuck fixture and a tip fixture; each of the chuck fixture and the tip fixture has a cone vertex angle of 109.5 degrees with an edge of the right-angle triangular pyramid as a generatrix and an inner cone surface slot made of the cone vertex angle; secondly, clamping the refined cube in a self-produced auxiliary fixture, rotating along a central line, feeding by a lathe tool at the moment, mounting a tip after roughly turning and then precisely turning; and finally, finishing processing the right-angle triangular pyramid. Two right-angle triangular pyramids can be turned from the refined cube once by repeatedly utilizing the method. The method has the advantages of being simple in method, high in processing precision and high in production efficiency without any special auxiliary tools, so that the processing cost is saved.
Description
Technical field
The invention relates to the processing method of non-revolved body in a kind of field of machining, relates in particular to a kind of method of utilizing conventional lathe turning right-angle prismatic cone.
Background technology
In field of machining, the processing of Rhizoma Sparganii cone belongs to the processing of non-revolved body, to its processing method, it is more difficult technical problem, utilize conventional machine tooling to be difficult to realize, even if utilize machining center to realize, also need loaded down with trivial details programming, more special assisted class instrument or fixture, therefore to processing staff, bring difficulty, cause the waste of resource simultaneously, reduced operating efficiency.
Summary of the invention
The object of the invention is to provide a kind of method for turning of right-angle prismatic cone, and process is simple, and machining accuracy is high, and production efficiency is high, and without any need for special defects aid, has saved processing cost.
The technical scheme of the invention: a kind of method for turning of right-angle prismatic cone, comprises the steps:
(1) blank material is processed into refining square, the length of side of square is the seamed edge of right-angle prismatic cone;
(2) self-control auxiliary clamp, auxiliary clamp consists of collet fixture and top fixture, and collet fixture and top fixture all have take 109.5 ° of circular cone drift angles that right-angle prismatic cone limit is bus and sleeping with the internal conical surface groove of circular cone drift angle system;
(3) will refine square (being workpiece) and be clipped between collet fixture and top fixture, the summit of workpiece is corresponding to the sleeping cusp of the positive Rhizoma Sparganii of collet fixture, and summit B, summit D and summit H enter in the sleeping cavity of the positive Rhizoma Sparganii of collet fixture; The summit of workpiece is corresponding to the sleeping cusp of top fixture, and summit, summit and summit enter in the sleeping cavity of top fixture, then above-mentioned fixture and workpiece in the lump clamping between lathe chuck end and top place;
(4) make above-mentioned fixture and workpiece on same axis, and press center line rotation, workpiece when rotated, lathe tool feeding, the in the situation that of reserved allowance for finish, the plane single solution for diverse problems that car breaking crown point B, summit D and summit H form removes;
(5) upper top, finish turning is removed allowance for finish along summit B, summit D and the formed plane of summit H;
(6) right-angle prismatic cone machines.
Described refining square can be made two right-angle prismatic cones by a train.
Refining square is after removing the right-angle prismatic cone that summit is cusp, upper top, first uses the rough turn summit C of car breaking, summit F and the formed plane of summit G, then with finish turning, removes allowance for finish, and so far second right-angle prismatic cone machines.
The beneficial effect of the invention: owing to adopting homemade auxiliary clamp, collet fixture in auxiliary clamp and top fixture all have take 109.5 ° of circular cone drift angles that right-angle prismatic cone limit is bus and sleeping with the internal conical surface groove of circular cone drift angle system, make like this workpiece firmly be fixed in the cavity of collet fixture and top fixture, because top fixture is sleeping, play auxiliary positioning effect, the normal clamping that has so just fully guaranteed workpiece is fixed, and has also guaranteed machining accuracy simultaneously; Because do not need to utilize machining center and loaded down with trivial details programming and save more auxiliary clamp, so just the irregular workpiece processing for small lot has improved operating efficiency, has saved processing cost.
