Abstract
The invention discloses a machining method for a special-shaped workpiece of which the surface is an irregular spatial curved surface. The irregular spatial curved surface of the special-shaped workpiece is regarded as an irregular surface formed by combining a plurality of slopes, cylindrical surfaces or conical surfaces and curved surfaces; then clamping positions of fixtures are arranged on the slopes, the cylindrical surfaces and the conical surfaces, so that the special-shaped workpiece is clamped and fixed; only the positions which are not clamped are machined, so that unmachined lugs are formed at the clamping positions; and then the remaining lugs are ground manually so as to finish machining of the special-shaped workpiece. The clamping positions are on the regular-shaped surfaces, and parts on the regular surfaces expect the clamping positions are all machined, so that the unmachined parts on the clamping positions only need to be manually ground to be the same as the regular surfaces on which the bottom parts of the unmachined parts are located; manual regular surface machining is easily realized; and therefore, the production cost is greatly lowered, and compared with a machining method adopting frequent overturning and clamping operations, the machining method disclosed by the invention is advantaged in that the efficiency is improved.
Description
Technical field
The present invention relates to the manufacture field of mechanical field special-shaped part, a kind of surface is the shaped piece processing method of Anomalistic space curved surface specifically.
Background technology
Often adopting Digit Control Machine Tool to process a kind of thin wall special-shaped class part in commercial production, the profile of this part is made up of multiple space curved surfaces, maximum gauge about 2.5 meters, part thinnest part wall thickness only 40mm, and profile is extremely irregular, and parts fixation processing has great difficulty.
At present, special process equipment is mainly made for clamping processing for similar thin wall special-shaped parts fixation processing method, and adopt the method that thin wall special-shaped parts fixation adds man-hour, owing to part needs repeatedly to overturn clamping, and after processing, shape can change every time, needs make a lot of special process equipment, not only result in cost and are greatly improved, and the efficiency processed is also very low.
Summary of the invention
In order to solve that prior art adopts the cost problem high, inefficient that repeatedly upset installation way exists when processing opposite sex part, the invention provides the shaped piece processing method that a kind of surface is Anomalistic space curved surface, the method is by after rationally selecting clamping position to carry out a Digit Control Machine Tool processing, in manual methods clamping position is polished into ruled surface or namely inclined-plane completes processing, thus reducing production cost, and improve working (machining) efficiency.
The present invention solves that the technical scheme that above-mentioned technical problem adopts is: a kind of surface is the shaped piece processing method of Anomalistic space curved surface, its clamping is fixed by the profile according to shaped piece, then program on Digit Control Machine Tool, and be processed according to programme-control Digit Control Machine Tool, the described profile clamping according to shaped piece is fixing to be referred to, the Anomalistic space curved surface of shaped piece is regarded as by several inclined-planes, the irregular surface that the face of cylinder or taper seat and curved surface are combined into, then the clip position of fixture is set in each inclined-plane, on the face of cylinder and taper seat, thus shaped piece clamping is fixed,
Described adding man-hour according to programme-control Digit Control Machine Tool, only process non-clamping position, so that after process finishing, forming unprocessed boss at clamping position, then the left boss of manual polishing is to requiring size, thus completing the processing of shaped piece.
During described manual polishing, need to polishing situation being verified, method of calibration is: utilizes the boss that edge of a knife chi inspection is polished, and judges whether consistent with the inclined-plane at this boss place, the face of cylinder or taper seat technological parameter.
Beneficial effect: the present invention is by regarding as by some inclined-planes by the Irregular Boundary Surface of shaped piece, the rule face such as the face of cylinder and taper seat and Irregular Boundary Surface are put together, then clamping on ruled surface, utilize Digit Control Machine Tool that non-clamping position is processed, then manual grinding clamping position, owing to clamping position is on rule face, and place completion of processing all except clamping position on this face, therefore, as long as by local manual grinding unprocessed on clamping position to identical with the regular face at place bottom it, and manual grinding rule face is easily achieved, so not only considerably reduce production cost, and relative to overturning frequently, clamping operates, efficiency have also been obtained raising.

Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is further elaborated.
A kind of surface is the shaped piece processing method of Anomalistic space curved surface, its clamping is fixed by the profile according to shaped piece, then program on Digit Control Machine Tool, and be processed according to programme-control Digit Control Machine Tool, the described profile clamping according to shaped piece is fixing to be referred to, the Anomalistic space curved surface of shaped piece is regarded as the irregular surface being combined into by several inclined-planes, the face of cylinder or taper seat and curved surface, then the clip position of fixture is set on each inclined-plane, the face of cylinder and taper seat, thus shaped piece clamping is fixed;
Described adding man-hour according to programme-control Digit Control Machine Tool, only process non-clamping position, so that after process finishing, forming unprocessed boss at clamping position, then the left boss of manual polishing is to requiring size, thus completing the processing of shaped piece;
During described manual polishing, need to polishing situation being verified, method of calibration is: utilizes the boss that edge of a knife chi inspection is polished, and judges whether consistent with the inclined-plane at this boss place, the face of cylinder or taper seat technological parameter.
Make elaboration in conjunction with the application in actual production of 1��9 pair of technical scheme of accompanying drawing and illustrate:
A), first determine that clamping position is at surrounding, endoporus auxiliary clamping according to External Shape situation;
B), according to the multiple curved surface situation of part, process can stay boss for clamping in surrounding more, big end is determined upward after final processing, at A, B two reserved boss in inclined-plane, place place, namely the 1 of Fig. 3 and Fig. 5,2 places, from Fig. 3 and Fig. 5,1 place can be regarded as the combination on inclined-plane (or the face of cylinder, taper seat) and inner sunken face (arcwall face), 2 places can be regarded as the combination on inclined-plane (or the face of cylinder, taper seat) and another face, therefore, clamping position is determined on the inclined-plane (or the face of cylinder, taper seat) at this two place;
C), this chamfer length is about about 130mm, it is considered to situation more accurately during machined surface more long final inspection, and considers clamping stationarity, it is determined that reserved boss is sized to 70mm;
D), work out part program, boss is reserved;
E), follow procedure be processed, finally only retain A, B two boss at inclined-plane, place place by constantly exchanging clamping position;
F), manual grinding remove boss, polishing boss with processed bevel altitude difference within 0.2mm time, start polishing situation is constantly verified;
G), method of calibration is: edge of a knife chi is placed in part convex platform place curved portion, it is ensured that after polishing position with process inclined-plane and connect flat, namely smooth gapless reaches requirement.
