Abstract
The invention discloses a method for machining an aluminum alloy thin-wall cabin. A position of a milling tool is changed by modifying a machine tool, and in the process of machining a long cylindrical thin-wall part, milling is replaced by turning, and complex thin-wall parts are machined in a turning and milling combined mode. Some large-size sealing grooves of the cabin are machined by a milling method, a high-quality key groove milling tool is adopted, numerical control programming is performed and a circular trace is formed; the machining method has simple machining processes, product yield is high and the products have stable quality; and in the machining process, a spindle rotating speed, feeding amount and other cutting parameters are required strictly, so high surface quality can be guaranteed, and the sealing requirement is met.
Description
Technical field
The present invention relates to a kind of aluminium alloy machine-tooled method, specifically, the present invention relates to a kind of improved aluminium alloy thin-walled cabin body machine-tooled method.
Background technology
At present, China's aerospace industry development is risen in this world, and the space class product is made the field and more and more magnified.In China's space product, mainly in the majority with cabin body product.Typical section structure size is big, the profile complexity, the thin difficult processing of cabin body wall; the sidewall covering thickness of thin-wall case structure cabin body is generally 1mm～3mm; the dimensional accuracy of cabin body and Geometrical Tolerance Principle height, these characteristics cause cabin chaeta base to adopt common machine-tooled method difficulty big, manufacturing procedure complexity; the product that processes is yielding, and yield rate is low.
Summary of the invention
Technical problem to be solved by this invention provides that a kind of mechanical processing difficulty is little, and manufacturing procedure is simple, guarantees the aluminium alloy thin-walled cabin body machine-tooled method of yield rate.
For solving the problems of the technologies described above, the present invention is achieved by the following technical solutions:
1, realizes cabin body machined by transforming lathe, overcome the cabin body because the big problem of difficulty of processing that long cylinder shape of self and thin-walled characteristics cause.Concrete way is dismantle three-jaw on the lathe and the knife rest on the supporting plate, on supporting plate, install a flat board vertical additional with supporting plate, on flat board, open two parallel slots, guarantee that groove is parallel with main shaft, on two grooves, install two clips additional and be used for clamping parts, one end of workpiece is with the three-jaw clamping and be installed on the dividing head, and the rotation of main shaft makes the Tool in Cutting inner cavity of component in conjunction with the big rotation of calibration, can realize the on-circular cutting of inner chamber.
In addition, the main shaft of lathe is dismantled and is installed the blade row of a ф about 50 (proof strengths) behind the three-jaw additional, and the clamping fabrication hole of making cutter on the blade row guarantees that cutter can regulate.Adorn blade row on the main shaft, on blade row, adorn the Milling Process that a pneumatic tool heads can realize inner chamber.
By changing the position that milling cutter is placed, when processing elongated cylindrical thin-walled parts, realize milling with car generation, car, mill the mode that develops simultaneously and process comparatively complicated thin-walled parts, challenge is oversimplified.
2, for the processing of some large scale seal grooves, select to mill processing.On the body upper and lower side frame of cabin, multiple tracks rectangular seal groove is arranged, because the seal groove diameter is big, and three surface roughnesses of seal groove are not less than Ra1.6, so processing difficulty relatively.If select common Vehicle Processing, adopt the cutting knife cutter, if seal groove broad, cutting knife equates that with the seal groove width seal groove one-pass is worked into size, and then the seal groove surface roughness is difficult to reach requirement, and collapse cutter easily, cutting data is also very little, so the cutting knife width is less than the seal groove width, and the processing of feed several times.This processing method operation more complicated, strict to the geometric parameter and the cutting parameter of cutter, tipping takes place easily, be not suitable for batch production requirements.The processing method that the present invention adopts is to mill processing, adopts the high-quality cotter mill cutter, and numerical control programming is walked a circular trace, and this processing method manufacturing procedure is simple, product percent of pass height, steady quality.In process, cutting parameters such as the strict speed of mainshaft, the amount of feeding could guarantee higher surface quality, satisfy seal request.
The invention has the beneficial effects as follows that by improving lathe and selecting for use and mill processing, cabin body difficulty of processing is diminished, manufacturing procedure becomes simple, and has also guaranteed certain yield rate.
The specific embodiment
Specific embodiment of the present invention is:
1) material machined into.
2) pincers bed processing.
3) drilling machine processing.
4) seal groove milling machine processing.
5) according to the layout inspection of finished product drawing.
6) surface, cabin japanning.
7) be up to the standards, pack, put in storage.
It is emphasized that: above only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment did.
