Precise scribing method for thin-wall special-shaped casting cabin

Abstract

The invention relates to a method for precision lineation of a thin-wall special-shaped cast cabin. A rough lineation mode of marking out outline processing molded surface lines based on the outline rough standard, a data collection mode of using a laser measuring machine to scan inner cavity molded surface, a mode of establishing a workpiece coordinate system according to inner cavity point cloud and a mode of accurately adjusting the outline processing molded surface lines are adopted. Machinability of parts can be pre-judged, wall thickness uniformity in the processing process is guaranteed, thin points do not occur, lineation precision of the thin-wall special-shaped cast cabin is improved, the problem of wall thickness unevenness is effectively solved, the product pass rate is improved, and the method can generate very large economic benefits when applied to actual production and is very high in application prospect.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and relates to a precision scribing method for a thin-wall special-shaped casting cabin. Background technique [0002] Because of the characteristics of light weight, material saving, and compact structure, thin-walled casting cabin parts have been widely used in various types of missile weapons and equipment. With the continuous improvement of the technical and tactical indicators of missile weapon products, the weight requirements are becoming more and more stringent, generally not exceeding 15% of the theoretical weight, and the casting allowance of the inner cavity is correspondingly reduced to 0.5mm~1mm, so controlling the wall thickness is processing The key technology in the production process is also the bottleneck technology in the current production. In machining, it is often scrapped because the marking position is not accurate enough, resulting in uneven wall thickness ...
