Abstract

The invention relates to a processing method for preventing a bar-shaped thin-wall part from deforming. The processing method comprises the following steps: blanking a circular bar, placing on a turning lathe, turning an outer circle and punching an inner hole, wherein a 0.5mm allowance is left for diameters of the outer circle and the inner hole, and a total length is in a designed size; placing the circular bar onto a boring lathe, clamping the outer circle, precisely boring the inner hole to be in the designed size; and lastly, placing a core bar, positioning an end face, and precisely turning the outer circle till the outer circle achieves the designed size, thereby forming a product. Compared with an original processing method, the processing method has the advantages that an abandoned product caused by uncertain factors during a processing process is avoided, by changing the processing method, namely, firstly processing the outer circle and the inner hole of the product to be semi-finished and then precisely processing for ensuring the precision and the size of the product.

Description

A kind of processing method that prevents the distortion of clavate thin-walled parts
Technical field
The invention belongs to mechanical manufacturing field, particularly a kind of processing method that in process, prevents the distortion of clavate thin-walled parts.
Background technology
In mechanical industry, production and processing clavate thin-walled parts is the thin and higher soft material (as: aluminium bar, copper rod etc.) of product required precision of the difficult problem, particularly wall that let the people have a headache always, and that is difficult to guarantee its product size and required precision especially.The machined personnel have thought a lot of ways, but effect is not fine.
Summary of the invention
The technical problem that the present invention will solve provides a kind of clavate thin-walled parts that prevents as far as possible and in process, produces the processing method of distortion.
A kind of processing method that prevents the distortion of clavate thin-walled parts: earlier with the pole blanking, get on the bus wheeled litter cylindrical and punching, cylindrical and diameter of bore all stay the 0.5mm surplus, accomplish design size to length overall; Go up boring machine again, the outer bundle of circles endoporus right boring of clamping is to design size; Go up at last plug with end face location finish turning cylindrical, the cylindrical finish turning to design size, is formed product.
Compare with original processing method; The present invention is through changing processing method promptly: first converted products cylindrical and endoporus to semifinishing state; Fine finishining makes that product precision and size are able to guarantee then, thereby has avoided the uncertainty of bringing in the processing and the product rejection that causes.
Description of drawings
Fig. 1 is an exemplar structural representation of the present invention;
The specific embodiment
The objective of the invention is to, the original processing method that changes the high accuracy thin-wall part guarantees that its precision and product are indeformable.Original processing method is: use that numerically controlled lathe is holed, half right boring and right boring hole, thick, finish turning cylindrical is processed.But thin and this softer series products of material for wall will cause cylindrical, interior hole dimension instability and axial cylindrical and endoporus to be prone to produce phenomenons such as tapering like this, makes product rejection rate very high.
This case is the processing that exemplar carries out thin-walled parts with Fig. 1, and this exemplar is a thin-wall bush, excircle dimension φ 15 ± 0.005mm, and interior hole dimension φ 13 ± 0.001mm, fineness requires 0.8; That is to say that wall thickness has only 1mm, technical staff's research of discussing before processing, decision adopt three kinds of schemes to manufacture experimently.
First kind of scheme:
Earlier the pole blanking is become the long material of 100mm, turning and plane, length overall is handled properly, and cylindrical grinding is to size, and the reprocessing endoporus is to finished product;
Second kind of scheme:
First with the pole blanking, get on the bus wheeled litter cylindrical and punching, cylindrical and diameter of bore all stay the 0.5mm surplus, accomplish design size to length overall; Go up boring machine again, the outer bundle of circles endoporus right boring of clamping is to design size; Go up at last plug with end face location finish turning cylindrical, the cylindrical finish turning to design size, is formed product;
The third scheme:
Earlier, directly go up precision machine tool then, plane, turning, boring, tune, plane, bore hole, be processed into product the pole blanking.
Above-mentioned three kinds of methods are respectively processed 100, and check at last draws, first kind of scheme qualification rate 45%, and the scuffing of damaging is more serious, and the product slight deformation is serious; Second kind of scheme qualification rate 97%, product does not have the scuffing of damaging, and product is out of shape in claimed range; The third scheme qualification rate 38%, product does not have the scuffing of damaging, and the product distortion is more serious.We have carried out contrast processing to other a lot of high accuracy thin-wall parts again simultaneously; Draw thus: when the ratio of product processed wall thickness σ and cylindrical d during less than 1: 15 (wall thickness σ >=0.8), the qualification rate of the product that employing scheme 2 is worked it out can reach more than 95%.The best approach that can to draw second kind of scheme thus be processing thin-walled part.
Can find out when the machining high-precision thin-wall part product by above-mentioned trial result, adopt second method not only can guarantee dimensional accuracy of products, and the damaging to scratch etc. and also obtained effective control of the distortion of product and products thereof surface.Adopt processing method of the present invention can must prevent effectively that not only thin-walled parts from adding the distortion in man-hour, and can also guarantee surface quality of products.
