Problems solved by technology

However, the above-mentioned technologies are only suitable for processing outer circles, and the aspect ratio is relatively small, and the material belongs to general steel. s Processing problems of ≥6 special steel, maraging steel, etc. can’t be solved
At the same time, the above-mentioned tooling needs to be supported by the workpiece due to its own weight, so it will cause deformation of the slender and thin-walled workpiece, resulting in a low pass rate of the workpiece, and the process ring must be exposed to light after each alignment, which is a consumable and increases the manufacturing cost.

Abstract

The invention relates to a processing method and technological equipment for a cylindrical thin and long thin-walled workpiece, which comprises positioning technological equipment and aligning technological equipment, wherein the positioning technological equipment consists of a connecting cylinder, a connecting flange, a positioning cylinder, a compression block, a compression screw, a stop nut and a connection screw; and the aligning technological equipment consists of an aligning technological equipment bottom plate, a bearing pedestal, a core shaft and a ball bearing. The processing method of the invention comprises a processing method suitable for manual operation of ordinary lathe and a processing method for operation of a hydraulic clamping center rest. The invention has the advantages that the deformation of the cylindrical thin and long thin-walled workpiece brought by clamping can be effectively reduced, the influence of workpiece clamping force on the workpiece processing precision is reduced, the processing quality is improved, the processing procedure is simplified, the processing time is shortened, the processing efficiency is improved, the high-quality product rate reaches 100%, the cost is saved at the same time, and the effect in batch production is more obvious.

Description

technical field [0001] The invention relates to the machinery manufacturing industry, and relates to a processing method and technological equipment for cylindrical thin-walled parts. Background technique [0002] At present, according to the requirements of certain product characteristics, mechanical components are developing towards lighter and thinner, and higher processing quality requirements, which put forward higher requirements for the machining of thin-walled parts. In the processing of cylindrical slender and thin-walled parts, the tooling is required to have good clamping performance, which can provide sufficient clamping force, so that the relative displacement between the workpiece and the tooling cannot occur, and at the same time, the workpiece will not be clamped due to clamping. Excessive force causes clamping deformation and affects the final processing quality of the workpiece. [0003] Prior to the present invention, the patent applications of 2008200543...
