Embodiment Construction

[0041] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings and technical solutions.

[0042] Such as Figure 1 to Figure 7As shown, the present invention is a clamping system for processing the outer wall of a thin-walled cylinder. Body 8, workpiece 9, movable baffle 10, positioning nut 11, lock nut 12 and connecting bolt 13;

[0043] A method for clamping the outer wall of a thin-walled cylindrical part by turning, including two parts: radial auxiliary support and axial clamping;

[0044] The specific steps of radial auxiliary support are as follows:

[0045] (1) By rotating the adjusting nut 6, under the action of the compression spring 3, the connecting rod 7 drives the elastic body 8 to move radially until it contacts the inner wall of the workpiece 9 and exerts a certain supporting force. The size of the supporting force is adjusted by rotating the adjusting nut 6 To achieve stepless...

Abstract

The invention belongs to the field of machining, and provides a clamping system and method for turning the outer wall of a thin-wall cylindrical part. The clamping system comprises a center shaft, a fixed baffle, compression springs, studs, gaskets, adjusting nuts, connecting rods, elastic bodies, a movable baffle, a locating nut, a locking nut, connecting bolts and other components. The clampingsystem is suitable for thin-wall cylindrical parts of multiple inner diameter sizes, the clamping system is divided into a radial auxiliary supporting structure and an axial locating and clamping structure, and clamping deformation of the thin-wall cylindrical part is effectively reduced. According to the clamping system, the axial clamping force / radial supporting force can be adjusted according to different workpiece axial and radial rigidities and the magnitude of the axial clamping force / radial supporting force and workpiece deformation can be measured. The clamping system is simple in structure, reliable in locating and wide in application range, the supporting force, the clamping force and workpiece deformation can be controlled and measured, and the effective solution method is provided for machining and clamping of small and medium size thin-wall cylindrical components.

Description

technical field [0001] The invention belongs to the technical field of cutting processing, and relates to a system and method for clamping the outer wall of a thin-walled cylindrical part by turning. Background technique [0002] With the development of my country's aviation, aerospace and navigation industries, thin-walled cylindrical components are more and more widely used in the development of major national defense equipment such as large aircraft, large ships and aerospace vehicles, such as aero-engine casings and drums, etc. The components are all thin-walled cylindrical components. It can be seen that the thin-walled cylindrical structural parts can better meet the design and manufacturing requirements of modern advanced aerospace vehicles. Therefore, with the continuous improvement of the performance requirements of modern aerospace vehicles, the size of thin-walled cylindrical components has also increased significantly, and the wall thickness has gradually become ...
