Magnetically Guided Pneumatic Variable Stiffness Mirror Milling Flexible Support Mechanism

Abstract

The invention discloses a magnetically-guided pneumatic variable rigidity mirror image milling flexible supporting mechanism. A supporting head part and a driving end part are included. The supportinghead part comprises an air cylinder base, rib plates with circular rings are evenly distributed on the outer wall of the air cylinder base, and each circular ring and one sleeve are jointly arrangedon a full thread universal ball and fixed together through a locking nut. The edges of the sleeves are provided with side rib plates for installing magnet arcs. An air cylinder is connected with an air cylinder base threaded hole through a thread on the outer wall of the air cylinder and locked through a locking nut. A column universal ball is arranged on an air cylinder piston rod, and a positioning nut is used for auxiliary positioning. The driving end part comprises a driving end base, ribbed plates are evenly arranged on the outer wall of the driving end base and used for being connected with a magnet ring through full-thread universal balls, fixing is conducted through locking nuts, and the magnet ring is opposite to the oppositely-arranged faces of the magnet arcs in magnetism. By means of the device, the configuration requirement for supporting end software and hardware in mirror image milling equipment can be simplified, and vibration is effectively restrained.

Description

technical field [0001] The invention relates to a flexible support mechanism for mirror image milling, in particular to a support mechanism for mirror image milling processing of thin-walled parts, which is mainly used to realize variable stiffness follow-up of thin-walled parts with different curvatures and different stiffnesses in the process of mirror image milling. , Conformal flexible support. Background technique [0002] Large lightweight alloy thin-walled parts are widely used in the aerospace field. Traditional processing methods for large skinned thin-walled parts include chemical milling and pattern milling. Compared with these traditional processing methods, due to the characteristics of high efficiency, economy and environmental protection of mirror image processing, This processing method has been more and more applied to the processing of thin-walled parts. The mirror image processing system has a processing mechanism and a supporting mechanism that are symme...

Problems solved by technology

This invention uses multiple air cylinders to adjust the size of the support force, but this invention needs to ensure the mirror image pose of the support end and the end of the milling end robot during the machining process, and the machining trajectory of the support side and the milling side when milling thin-walled parts with different curvatures The design of the synchronization algorithm has higher requirements; and through actual experimental verification, it is found that compared with a single cylinder point-to-point support, multiple cylinder supports have a very limited effect on vibration suppression, but will increase the weight of the support head
