Embodiment 1

[0049] The purpose of this embodiment is to provide a processing method for casting the special-shaped mounting edge of the casting cone ring block, which is used to solve a series of problems affecting the processing quality and efficiency of the parts caused by the poor structural manufacturability of the casting cone ring block special-shaped mounting edge parts The problem.

[0050]This embodiment specifically provides a processing method for casting a special-shaped mounting edge of a cone ring block, which at least includes:

[0051] A. Rough datum planning: determine 4 rough datum points 2 at the inner side walls of the upper and lower ends of the casting blank 1.

[0052] In the prior art, the initial rough datum of the casting blank adopts three dimensional datum points on the cone surface. Although the coincidence of the design datum and the process datum is realized, the three datum points on the cone surface are affected by various factors such as small Factors su...

Abstract

The invention discloses a machining method for a cast cone ring block special-shaped mounting edge. The machining method at least comprises the steps of rough datum planning, process fine datum machining and positioning, milling procedure centralized machining and positioning and the like. In order to solve the machining problem of the cast cone ring block special-shaped mounting edge and carry out process structure analysis and planning, firstly, rough datum selection is emphasized, a rough datum structure is redesigned and selected, and rough machining positioning and clamping stability is guaranteed; secondly, process fine datum machining and positioning are accurate; and thirdly, a milling procedure and a positioning mode are integrated. According to the machining method, the machining mode of the cast cone ring block special-shaped mounting edge is converted, namely, single machining of common equipment is converted into machining of an integrated machine tool, and the remarkable effects are achieved in the aspects of improving the part machining quality, improving the machining efficiency, reducing the tool cost and the like.

Description

technical field [0001] The invention relates to the field of aerospace technology, and in particular provides a processing method for casting a special-shaped mounting edge of a cone ring block. Background technique [0002] The special-shaped mounting edge parts of casting cone ring block are widely used in the field of aero-engine technology. The area of ​​the nozzle cross-section of the engine. It is very difficult to process the special-shaped mounting edge of the cone ring block, and the difference in the processing quality of a single piece will significantly cause some performance indicators of the engine to fail to meet the design expectations. Therefore, it is very necessary to design and verify the stability and reliability of the special-shaped mounting edge parts of the casting cone ring block. However, the structure of such ring block parts [0003] The mounting edge of the casting cone is used as a general model part, and its production volume is large. Due...
