Embodiment

[0038] (1) According to the size of the round beam of the instrument board, make three oil-surface mixtures with different mass ratios, that is, weigh 600g of engine oil, 2000g of flour to be made into oil-surface mixture I, and weigh 800g of machine oil and 2000g of flour to be prepared into oil-surface mixture II , weigh 900g of engine oil and 2000g of flour to be made into oil-noodle mixture III;

[0039] (2) Put the flour into the measuring container, sprinkle engine oil on the flour gradually, and keep kneading the flour with your hands at the same time, so that the engine oil and the flour are in full contact until there is no remaining dry flour, and store the prepared oil-surface mixture in a sealed container. surroundings;

[0040] (3) Use a scraper to remove the burr of the part, and wipe the surface of the groove of the part with a non-woven cloth moistened with alcohol to remove oil and metal chips;

[0041] (4) According to the size of the part groove, the oil su...

Abstract

Disclosed is a padding supporting method for enhancing thin-walled workpiece machined rigidity. Engine oil and flour are mixed according to a specific ratio and then padded into a cavity of a thin-walled workpiece, the whole rigidity of the thin-walled workpiece is improved, natural vibration frequency of the workpiece is changed, flutter is reduced, cut machined deformation of the thin-walled workpiece is reduced, the problem that workpiece surface qualities are affected due to poor rigidity and flutter can be solved, and machining accuracy and surface qualities of the thin-walled workpiece can be guaranteed. By means of the successful development of the padding supporting method, the difficulty of machining of the thin-walled workpiece during model development can be technologically solved, the machining scheme of the thin-walled workpiece and mixing ratio parameter of engine oil and flour can provide high reference value and certain guiding significance for high-efficiency precise machining of numerous thin-walled irregular workpieces which are high in accuracy requirements, complicated in structures and especially not easy to clamp in national defence industry fields of aviation, aerospace, weaponry and the like, and the padding supporting method for enhancing the thin-walled workpiece machined rigidity can be used for guiding actual production.

Description

technical field [0001] The invention relates to a filling and supporting method, in particular to a filling and supporting method for enhancing the processing rigidity of thin-walled parts, and belongs to the technical field of forming tooling processing design. Background technique [0002] Many important parts in modern aviation, aerospace, weapons and other defense industries are thin-walled aluminum alloy structures, and have the characteristics of complex structures and high precision requirements for parts, such as aluminum alloy overall frames, beams and large overall wall panels in the aerospace field. Although the current advanced CNC machining equipment can achieve high rigidity and precise motion control, due to the poor rigidity of thin-walled structural parts, they are affected by factors such as residual stress, clamping force, cutting force, and cutting heat during processing. , Thin-walled structural parts are prone to processing deformation and cutting vibra...
