Description

A method of control blowing model or so wing deflection
Technical field
The invention belongs to technical fields of mechanical processing, and in particular to a kind of side for controlling blowing model or so wing deflection Method.
Background technique
Blowing model or so wing be usually have the plate of monolith by lathe milling, vehicle, cut etc. process after complete.It is existing Wing model processing technology, during roughing, semifinishing, wing will appear biggish deflection, more than wing plus The requirement of Chinese musical scale cun, and since the requirement on machining accuracy of wing model is higher, quality and technical requirements to guarantee last are adding During work, need carry out semifinishing repeatedly, repeatedly by orthopedic and light-exposed benchmark so that the process-cycle of wing model It is long, and since each machining deformation amount is big, so that product quality is not easy to control.
Summary of the invention
It is an object of the invention to: above-mentioned deficiency in the prior art is solved, a kind of control is provided and is dried model or so machine The method of wing deflection processes wing model using this method, can reduce the deflection of wing in process, saves processing Process shortens the process-cycle of wing model.
To achieve the goals above, a kind of the technical solution adopted by the present invention are as follows: control blowing model or so wing deformation The method of amount, includes the following steps,
(a) roughing: being fixed on lathe for plate, processes wing semi-finished product by roughing surplus;The wing semi-finished product With opposite first aerofoil, the second aerofoil, and multiple sides of connection first aerofoil and the second aerofoil, wherein described in one Side is the connecting pin of wing and fuselage;First aerofoil of the wing semi-finished product reserves multiple first technique heads, in the machine Reserve the second technique head in the connecting pin of wing semi-finished product;Multiple third techniques are reserved in the second aerofoil of the wing semi-finished product Head, and relief hole is processed in the second skill head;Wing semi-finished product are heat-treated again, the wing semi-finished product after heat treatment are set In coolant liquid, keep the first aerofoil of the wing semi-finished product parallel with vertical direction, it is cooling in coolant liquid;
(b) semifinishing: by above-mentioned steps (a), treated that wing semi-finished product are fixed on lathe, by semifinishing surplus, The first aerofoil and the second aerofoil of semifinishing wing respectively;Wing semi-finished product after ageing treatment semifinishing;
(c) it finishes: the wing semi-finished product after above-mentioned steps (b) ageing treatment being fixed on lathe, are finished respectively First aerofoil and the second aerofoil are to relevant technological standards;
(d) the wing semi-finished product after above-mentioned steps (c) finishing are fixed on lathe, first removal is located at described first First technique head of aerofoil, then the third technique head positioned at second aerofoil is removed, finally removal is located at described Second technique head of connecting pin, obtains wing finished product.
Existing wing processing technology is usually first to process two aerofoils during roughing, do not process connection The side of two aerofoils, but the technique head of the plate between two aerofoils as a whole will be connected to.Of the invention adds During work, in roughing, extra plate is removed, side is processed, independent first technique is only reserved on two aerofoils Head and the second technique head, it should be noted that, it is independent from each other between multiple first technique heads, the first technique head and the second technique Head is also independent from each other.Mutually independent first technique head and the second technique head, so that wing semi-finished product are being finished When, the deflection of processing can be reduced, and since the quantity of technique head is reduced, when wing semi-finished product are fixed on lathe, Fixed step is also reduced accordingly, shortens process flow.
Further, in the step (a), the roughing surplus is 2-8mm.
Further, in the step (b), the semifinishing surplus is 0.1-0.5mm.
Further, in the step (a), first technique head is identical with the number of the third technique head, and First technique head and the third technique head are symmetrical arranged.
Further, the first technique head number is 5-7.
Further, when the length of the wing finished product is 50cm-100cm, the roughing surplus is 2mm-5mm, The semifinishing surplus is 0.1-0.2mm, and the number of first technique head is 5, and the number of the third technique head is 5 It is a.
Further, when the length of the wing finished product is 100cm-200cm, the roughing surplus is 5mm-8mm, The semifinishing surplus is 0.2mm-0.5mm, and the number of first technique head is 7, the number of the third technique head It is 7.
The number that the first technique head is determined according to the size of wing finished product increases of technique head when size friendship is big Number, can be placed in process, wing semi-finished product deform.
Further, second technique head has orthogonal first arm and the second arm, first arm and described Second arm is connect with the connecting pin of the wing semi-finished product respectively, first arm, second arm and the wing semi-finished product Connecting pin between form the relief hole.Cross sectional shape of the relief hole in the plane parallel with first aerofoil be Right angled triangle.
Further, the first aerofoil of the wing semi-finished product have be sequentially connected first while, second while, third side and 4th side, the connecting pin are located at first side, and multiple first technique heads are located at second side and described Four sides are symmetrical arranged positioned at multiple third technique heads of second aerofoil and first technique head.
By adopting the above-described technical solution, the beneficial effects of the present invention are:
In the present invention, plate first passes through roughing, and the first aerofoil and the second aerofoil, and connection are processed on plate Multiple sides of first aerofoil and the second aerofoil are reserved with mutually independent first technique head and third technique on aerofoil Head is reserved with the second technique head in connecting pin, is machined with relief hole on the second technique head, roughing, semifinishing and In finishing passes, be all made of the mode placed vertically and carry out cooling wing, and after finishing, first remove the first technique head and Third technique head is removing the second technique head, due to being also machined with relief hole on the second technique head, then remove the first technique head and When third technique head, relief hole can absorb machining stress, reduces the machining deformation amount of wing.And in semifinishing, finishing In the process, the machining stress on wing semi-finished product can be discharged by relief hole, further reduction wing semi-finished product Deflection;Since deflection of wing semi-finished product during post-production is small, under less manufacturing procedure, so that it may reach Processing request saves the manufacturing procedure of wing model.Due to only having one side that there is technique head in wing semi-finished product, in half finishing In work, finishing passes, wing semi-finished product torsional deformation can be prevented, reduces clamping times when processing, saves process time.
In invention, when wing semi-finished product are cooling, wing semi-finished product are placed in coolant liquid vertically, can effectively reduce cooling The deflection of wing semi-finished product in the process.The modes of emplacement of cooling procedure, technique head in removal wing semi-finished product one side The mutual cooperation of processing technology and relief hole, so that wing model is in process, greatly Reducing distortion amount, saves and adds Work process.
Compared with manufacturing procedure in the prior art, the deflection in process is controlled by means of the present invention, Orthopedic wing semi-finished product repeatedly and light-exposed benchmark repeatedly are avoided, the operation difficulty of process is reduced, reduces processing Time cost and economic cost.
