Problems solved by technology

[0003] The traditional process of processing thin-walled shell parts is completed by ordinary lathes and ordinary milling machines. During the processing, the use of general-purpose fixtures will cause uneven compression force, which will cause compression deformation to the parts, and manual processing by the operator will cause poor consistency and mass production. The time efficiency is low, and the processing quality is greatly affected by the technical level of the operator. Ordinary machine tools cannot process special shapes, such as elliptical holes, inclined-plane step holes, etc. In addition, multiple tool changes during the processing process, trial processing will affect the processing quality of parts , easily lead to waste

Abstract

The invention discloses a thin-wall shell processing method which comprises a tool clamp, wherein the tool clamp comprises a mandrel; one end of the mandrel is equipped with a mounting column; the outer part of the mandrel is fixedly equipped with an outer ring body in a sleeving mode; a wide ring-shaped slot and a narrow ring-shaped slot are formed in the outer ring body; a step is arranged between one end of the outer ring-shaped body and the mandrel; an auxiliary pressure plate is arranged on the outer part of the step in the sleeving mode; one side of the auxiliary pressure plate is equipped with a nut; and the nut is in threaded connection with the mounting column. The thin-wall shell processing method comprises the following specific steps: step I, outer wall rough turning; step II,high-temperature tempering; step III, left end surface turning; step IV, right end surface turning; step V, clamp mounting; step VI, outer wall fine turning; and step VII, appearance processing. The thin-wall shell processing method performs processing through a high-efficiency machine tool, and a thermal-treatment tempering distressing process is added to release part processing inner stress; andthe necessity of designing a special clamp is combined, so that processing deformation is prevented, and part processing quality requirements are guaranteed.

Description

technical field [0001] The invention relates to the technical field of thin-walled shell processing, in particular to a thin-walled shell processing method. Background technique [0002] The traditional processing of thin-walled parts is completed by a single machine tool, which is updated to the advanced processing method of computer programming control, special fixture positioning, and multi-tool participation. [0003] The traditional process of processing thin-walled shell parts is completed by ordinary lathes and ordinary milling machines. During the processing, the use of general-purpose fixtures will cause uneven compression force, which will cause compression deformation to the parts, and manual processing by the operator will cause poor consistency and mass production. The time efficiency is low, and the processing quality is greatly affected by the technical level of the operator. Ordinary machine tools cannot process special shapes, such as elliptical holes, incli...
