Problems solved by technology

[0002] There are a large number of rotary structural parts in the field of aerospace machinery processing and manufacturing. Among them, thin-walled parts have the processing characteristics of thin wall thickness and poor control of wall thickness uniformity and consistency during processing. However, in the actual assembly process of such parts, their The wall thickness dimension is also a critical feature element, and requires high precision control of the dimension; according to the traditional processing method, the assembly and combination fixture is used for clamping and processing, and the deformation effect during the processing is difficult to control, and it is affected by the cumulative error of the combination fixture. Influenced by the impact, rework or rework or shape correction often occurs after processing, resulting in poor product size uniformity and precision control, low pass rate of one-time processing of products, and low processing efficiency, which cannot meet normal batch production and assembly requirements.

Abstract

The invention discloses a method for machining an aluminum alloy large-diameter thin-wall rotation part. The method comprises the steps that an external circle of a workpiece is clamped, and inner holes and the external circle of the workpiece are roughly machined; the inner hole in one end of the workpiece and the inner hole in the other end of the workpiece are roughly turned; the external circle of the workpiece is clamped, an inner cavity in the large-aperture end of a conical hole of the workpiece and a root circular bead are subjected to semi-finish turning, middle connecting ribs and through holes of the workpiece are subjected to finish turning, and the aperture and angle of the conical hole are detected through a sample plate after semi-finish turning is carried out; truing aroundis carried out to clamp the external circle of the workpiece, the clamping depth exceeds the middle connecting rib, and the middle connecting rib at the small-aperture end of the conical hole of theworkpiece is subjected to finish turning; the large-aperture end of the conical hole of the workpiece is positioned through a first positioning tool, the appearance of the taper of the outer ring of the workpiece is subjected to finish turning, and an inner cavity in the small-aperture end of the conical hole of the workpiece and a root circular bead are subjected to finish turning at the same time; and the inner cavity in the large-aperture end of the conical hole is subjected to finish turning again until the wall thickness meets the design requirement. The part machined through the method is high in consistency, good in surface smoothness and very high in product precision.
