Embodiment Construction

[0039] 1) see figure 1, the present invention is a vacuum adsorption system for clamping and fixing thin plate milling, including a vacuum platform 1, a base 2, a rubber sealing strip 3, pipelines, a digital vacuum gauge 4, a vacuum pump 5 and other parts. The position connection relationship between them is: the vacuum platform 1 is located on the base 2, the rubber sealing strip 3 is placed in the sealing groove on the base 2 and the vacuum platform 1, and the pipeline is composed of a threaded gas nozzle 12, a PTFE tube 6, and a ferrule 7. A three-way joint 8 and a threaded connector 9 are used to connect the base 2, the digital display vacuum gauge 4 and the vacuum pump 5.

[0040] The vacuum platform 1 is processed from a thick aluminum plate, such as figure 2 Material shown is 6061-T6. The overall shape of the vacuum platform 1 is an inverted concave shape, which is convenient for installation and positioning with the base 2 (convex shape). The schematic diagram of t...

Abstract

A vacuum adsorbing system for clamping and fixing a thin plate during milling comprises a vacuum platform, a base, a rubber sealing strip, a pipeline, a digital display vacuum gauge and a vacuum pump, wherein the vacuum platform is positioned above the base; the rubber sealing strip is placed in a sealed groove both in the base and the vacuum platform; the pipeline comprises a threaded air faucet, a teflon pipe, a clamping sleeve, a three-way joint and a threaded connecting head; the base, the digital display vacuum gauge and the vacuum pump are connected with each other by the pipeline; and a use method of the vacuum adsorbing system for clamping and fixing the thin plate during milling comprises seven steps. According to the invention, by using a vacuum technology and through uniformly adsorbing and fixing a thin plate part on the vacuum platform, a clamping deformation problem of a workpiece is preferably solved, the milling accuracy of the part is enhanced and the machining quality of the part is improved. The vacuum adsorbing system has better practical values and broad application prospects in the technical field of mechanical machining.

Description

technical field [0001] The invention relates to a vacuum adsorption system for clamping and fixing thin plate milling and its application method, which is suitable for milling processing of metal material thin plates such as aluminum alloy, aluminum-lithium alloy, etc., and belongs to the technical field of mechanical processing. Background technique [0002] In order to meet the comprehensive requirements of safety, economy, comfort, and environmental protection, in the selection of airframe materials and structures of new commercial aircraft, on the one hand, aluminum alloys, aluminum-lithium alloys and other lightweight materials with low density and high specific strength are selected. On the other hand, a large number of The multi-step thin-walled structure is adopted, such as the skin of the nose, middle and rear fuselage, etc., and the skin panel is partially thinned to form a multi-step thin-walled structure, which can reduce the weight of the skin panel by more than ...
