Flexible clamp for milling thin-walled workpiece with complex curved surface

Abstract

The invention discloses a flexible clamp for milling a thin-walled workpiece with a complex curved surface, and belongs to the field of machining. The flexible clamp comprises a vice clamp, a fluid carrying trough for accommodating a magnetorheological fluid, a magnetoresistive plate frame arranged at the upper part of the fluid carrying trough, and plate electrodes for providing a horizontal magnetic field, wherein the left side of the magnetoresistive plate frame is connected with a lead screw through threads; the right side of the magnetoresistive plate frame sleeves a supporting and positioning rod in a matching way; the upper end of the lead screw is connected with an operating crank; and the operating crank can drive the lead screw to rotate and drive the magnetoresistive plate frame to rise and fall. The flexible clamp provided by the invention can effectively reduce the machining deformation of the thin-walled workpiece with the curved surface, effectively restrains the vibration of the thin-walled workpiece with the curved surface during milling, lowers the machining noise, reduces the machining error, and guarantees high machining efficiency and high surface machining quality.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a flexible fixture for effectively suppressing the vibration of milling thin-walled parts with complex curved surfaces. Background technique [0002] In the aerospace industry, the milling task of thin-walled parts is crucial, and the variable thickness and thinning processing of thin-walled parts has always been a difficult problem in processing and manufacturing. Thin-walled plates with complex curved surfaces in aerospace structures have poor rigidity, and are prone to deformation and tool deviation during processing, and processing vibration is the main factor affecting its processing efficiency and processing accuracy.
