Integrated pneumatic variable-stiffness mirror milling flexible supporting device with real-time thickness measuring function

Abstract

The invention discloses an integrated pneumatic variable-stiffness mirror milling flexible supporting device with a real-time thickness measuring function. The device comprises a base, an end cover is fixed on the base; a sensor fixing step hole and a main thread through hole are formed in the base; a displacement sensor is fixed in the sensor fixing step hole; a main pin type cylinder is in threaded connection with the main thread through hole; a plurality of peripheral thread through holes are formed in the periphery of the base; an auxiliary pin type cylinder is in threaded connection with the interior of each of the peripheral thread through holes; the piston rods of the auxiliary pin type cylinders are in threaded connection with a switch connecting rod arranged in the end cover; auxiliary universal balls are in threaded connection with the right end of the switch connecting rod; the detecting rod of the displacement sensor is fixed with the piston rod of the main pin type cylinder in a parallel connection manner through the switch connecting rod; a center thread through hole is formed in the switch connecting rod in the horizontal direction; the left end of a main universal ball is in threaded connection with the center thread through hole; a through hole is formed in the end cover at the position corresponding to each of the auxiliary universal balls and the main universal ball. With the adoption of the integrated pneumatic variable-stiffness mirror milling flexible supporting device, the vibration of thin-walled workpieces is effectively eliminated.

Description

technical field [0001] The invention relates to a support device capable of real-time control of the processing thickness during the mirror milling process of thin-walled parts, which is mainly used for variable stiffness follow-up and movement of thin-walled parts with different curvatures and different stiffnesses during the mirror milling process. Conformal flexible support and real-time thickness control and measurement. Background technique [0002] Large light alloy thin-walled parts and grid parts are widely used in the aerospace field. The traditional processing methods for large thin-walled parts include chemical milling and pattern milling. Mirror milling has gradually replaced it due to its high efficiency, economy and environmental protection. The traditional method is used for the processing of thin-walled parts. During the mirror milling process, the tool and the support head are respectively located on both sides of the thin-walled part, and move symmetricall...
