Auxiliary clamp for inhabiting cutting machining vibration of thin-walled casing

Abstract

The invention discloses an auxiliary clamp for inhibiting cutting machining vibration of a thin-walled casing. The vibration of the thin-walled casing in a machining process can be effectively inhibited by fixing the auxiliary clamp to the inner wall or the outer wall of the thin-walled casing through the cooperation of a spring unit group and a hexagonal frame, so that the machining precision ofthe thin-walled casing is improved; the practicability is high, and the auxiliary clamp is fixed to the inner wall or the outer wall of the thin-walled casing according to the difference of the machining surfaces of the thin-walled casing; the auxiliary clamp can be adjusted correspondingly along with the change of the application environment by only changing the length of a connecting rod for thin-walled casings with different sizes, so that the application range is wide; a machine tool is not required to be improved, the auxiliary clamp is easy to use and low in cost; the auxiliary clamp iseasy to mount without the help of other power devices, and is suitable for different machining processes; the auxiliary clamp is simple in structure, and cannot affect the machining of various characteristic surfaces of the thin-walled casing; and enough knife feeding and retracting space is reversed even when the surface mounted with the auxiliary clamp is machined, so that as many characteristicsurfaces as possible can be machined in one mounting, and the mounting frequency is reduced.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to an auxiliary fixture for suppressing the chatter of thin-wall casing cutting. Background technique [0002] Aviation parts are characterized by lightness, thinness, and poor rigidity. Serious vibration or even chatter will occur during processing. Vibration will greatly reduce the processing accuracy and surface quality of the workpiece. [0003] In order to suppress the vibration in the process of machining, scholars at home and abroad have carried out a lot of research. The methods of suppressing vibration during machining are mainly divided into active method and passive method. The active method is mainly to control the cutting tools and tooling. For example, Dohner et al. optimized the control loop of the tool in the milling process and improved the processing efficiency. Rashid et al. used the adaptive control method to control the tooling in the milling pr...
