Abstract

A semicircular thin-wall workpiece processing tool comprises an inner hole tool, a Harvard clamp tool and a milling tool. When the semicircular thin-wall workpiece processing tool is used, the steps can be followed: fixing the inner hole tool at one end of an inner hole of a workpiece, clamping the end through a claw on a main shaft of a lathe, making the claw correspond to the position of a pressing screw, roughly turning an inner hole at the other end, the periphery of the excircle and the end face, turning over the workpiece, repeating above operations to roughly turning the whole workpiece, cutting the roughly turned workpiece into two semicircular workpieces through a molybdenum wire, milling cutting faces on the milling tool, folding the two semicircular workpieces and fixing the semicircular workpieces by the Harvard clamp tool, welding the two semicircular workpieces, and finely turning the periphery of the excircle, the inner hole and the end face. By using the semicircular thin-wall workpiece processing tool and the use method thereof, the periphery of the excircle of a workpiece can be processed, deformation caused by clamping can be reduced, and deformation caused by release of internal stress when the workpiece is cut.

Description

technical field [0001] The invention relates to a tooling for processing thin-walled parts, in particular to a processing tool for semicircular thin-walled parts and a method for using the same. The deformation of the workpiece due to the release of internal stress during the process. Background technique [0002] Thin-walled workpieces have been widely used in different mechanical fields because of their compact structure, material saving, and light weight. However, due to the problems of poor rigidity and low strength of thin-walled workpieces, they are easily deformed during processing, and it is difficult to ensure the processing of workpieces. quality. For semicircular thin-walled parts, on the one hand, the parts need to be processed into circular thin-walled parts, and on the other hand, the circular thin-walled parts need to be planed into two halves. Higher requirements are required, not only that the tooling is required to provide sufficient clamping force, so th...
