Abstract

The invention discloses a pneumatic type variable-rigidity flexible mirror-image milling supporting head for measuring thickness in real time. The pneumatic type variable-rigidity flexible mirror-image milling supporting head comprises a base; a pedestal is fixedly arranged on the base; a probe housing is in sliding connection in a central through hole; a thickness measuring probe is fixedly arranged in the probe housing; the left end of the probe housing is in threaded connection with a probe screw plug; one universal rolling ball is separately mounted at two circular-arc ends in each circular-arc through hole; the right end of one transfer screw plug is in threaded connection in a central step threaded hole; right ends of a plurality of inner hexagonal screw plugs are in threaded connection in peripheral mounting threaded through holes in a one-to-one correspondence mode; pneumatic cylinder mounting holes are separately formed in the middle of the right end of the transfer screw plug and in the middle of the right end of each inner hexagonal screw plug; the cylinder body of one air cylinder is separately mounted in each pneumatic cylinder mounting hole; and the piston rod of each pneumatic cylinder is in threaded connection with the probe screw plug or is separately in threaded connection with a polish rod of the universal rolling ball. The pneumatic type variable-rigidity flexible mirror-image milling supporting head can meet different-curvature supporting requirements of thin-wall parts.

Description

technical field [0001] The invention relates to a support device for mirror image milling of thin-walled parts, which is mainly used for flexible support with variable stiffness and real-time thickness measurement for thin-walled parts with weak rigidity and different curvatures during the mirror image milling process. Background technique [0002] Large light alloy thin-walled skin components are widely used in the aerospace field. The traditional processing methods for large skin thin-walled plates are chemical milling and pattern milling. Compared with traditional methods, mirror milling is based on its high efficiency, economy, and environmental protection. It has been increasingly used in 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, moving mirror-symmetrically along the surface of the thin-walled part, and always maintaining point-to-point normal supp...
