Abstract
The method of cover Vehicle Processing middle-convex and varying ellipse, be that utilization workpiece direction of feed produces ellipse in an angle with cover lathe tool rotation, in the feeding process, the angle that the direction of feed and the lathe tool of harnessing an animal to a cart revolve between the axis constantly changes, the cover lathe tool moves radially, thereby car goes out the middle-convex and varying ellipse profile.
Description
The present invention relates to mechanical manufacturing field, specifically, is a kind of method of overlapping Vehicle Processing middle-convex and varying ellipse profile.
The method of machining piston skirt section middle-convex and varying ellipse profile mainly contains two big classes at present: a class is Digit Control Machine Tool processing; One class is the processing of utilization hard mould profiling, as the middle-convex and varying ellipse three-dimensional explorator.Digit Control Machine Tool is owing to cost an arm and a leg, promote the use of to be very limited, hard mould exist make difficulty, can not exchange, the not high shortcoming of copying accuracy.The method of the cover Vehicle Processing middle-convex and varying ellipse profile that the present invention proposes has easy realization, simple in structure, and characteristics such as machining accuracy height are the Perfected process of processing middle-convex and varying ellipse profile.
The purpose of this invention is to provide a kind of economic, practical, process the method for middle-convex and varying ellipse profile accurately, there are the problems referred to above in processing middle-convex and varying ellipse profile in the present piston industry to solve.

The method of the machining convex ellipsoid by forming lathe that the present invention proposes, its principle are (with reference to the accompanying drawings one); The direction of workpiece (piston) feeding and the rotating shaft wire clamp one angle θ that overlaps headstock, thus cover lathe tool 10 goes out ellipse at workpiece 17 surperficial cars. Change angle θ according to certain rule, but just car goes out the ellipse of variation. The direction of feed motion of workpiece 17 is along with feed motion constantly changes under the control of pattern 13 among the figure, and namely the θ angle constantly changes, and is oval thereby car goes out to become. The axis that workpiece is done small rotation should overlap with point of a knife, and oval center is consistent with workpiece (piston) axis during with the small rotation of assurance workpiece. Draw bar chuck 21 is done small movement under the control of pattern 19, drive pull bar 1 and do vertically regular small movement, and lever 7 is being controlled cutter holder 9 and moved under the effect of pull bar 1, along with the feeding of workpiece, go out middle bulged curve at the surface of the work car. Cutter holder 9 moving directions should be consistent with the axis of the small rotation of workpiece. Synchronous fuel tank 14,18 is being controlled the movement of feed motion and pattern 19 according to certain rules, thereby in the surface of the work middle-convex and varying ellipse profile of harnessing an animal to a cart out.
Oval workpiece (piston) technology of existing cover Vehicle Processing is owing to the angle theta of direction of feed with cover headstock rotation can not change, so can only process constant ellipse.The invention solves that the workpiece direction of feed can change this question of substance according to certain rules continuously in the process, become ellipse piston-type surface problem thereby solved cover Vehicle Processing convexity.
Embodiment
In figure one, figure two, the 1st, pull bar, pull bar be along with main shaft rotates together, and the 2nd, sleeve, pull bar can be twitched in sleeve, and the 3rd, main shaft, the 4th, belt, the 5th, spring, the 24th, check ring, spring is pressed to the right side with pull bar, makes pressure head 20 be pressed in pattern 19 surfaces by draw bar chuck 21.Pull bar is rotatable in chuck 21, but can not twitch.Pull bar 1 is hinged with lever 7, and the control lever swing.Lever 7 drives cutter holder 9 and moves, and the direction that cutter holder moves is vertical with main shaft gyration axis 25, and the 6th, headstock, the 8th, cover headstock.The 10th, the cover lathe tool.Pattern 19 moves under oil cylinder 18 drives, and moves by pressure head 20-chuck 21-pull bar 1-lever 7-cutter holder 9 control cover lathe tools 10, and along with the feeding of workpiece, the cover lathe tool goes out middle bulged curve at the surface of the work car.The 17th, workpiece (piston), the 11st, anchor clamps, the 12nd, chuck body, the 13rd, pattern, the 14th, oil cylinder, the 15th, planker, the 16th, supporting plate.Chuck body 12 is fastened on the planker 15, planker 15 can be done feed motion along the guide rail on the supporting plate 16, supporting plate 16 can rotate around center line 27, the 23rd, pressure head, fixedly connected with planker 15, spring 22 is pressed on the supporting plate 16, by supporting plate 16-planker 15-pressure head 23 pressure head is pressed on the surface of pattern 13.Oil cylinder 14 is hinged with planker 15.Oil cylinder 14 promotes planker 15 and does feed motion, in the feeding process, pattern control planker, supporting plate rotate around center line 27, realize constantly changing in workpiece (piston) the 17 feeding processes angle theta of direction of feed 26 and spindle centerline 25, thereby at the surface of the work change ellipse of harnessing an animal to a cart out.The pivot center 27 of supporting plate 16 overlaps with the point of a knife of cover lathe tool 10.Oil cylinder 14 is synchronized with the movement with oil cylinder 18.Under the control of pattern 19 and 13, cover lathe tool 10 moves by predetermined rule, and the angle of workpiece 17 directions of feed 26 and cover lathe tool rotation 25 is by predetermined rule variation, thereby in the surface of the work middle-convex and varying ellipse profile of harnessing an animal to a cart out.
