Embodiment
[0067] (1) Select the number of vacuum adsorption modules according to the size of the thin plate parts 13 and assemble them to form a vacuum adsorption tooling. If you want to clamp thin plate parts 13 with a size of 2000mm*2000mm, you need to choose 5 vacuum adsorption modules (the size of a single vacuum adsorption module is about 2100mm*400mm) and splicing with the pressure plate components 4 on both sides, the structure of the vacuum adsorption module as above. Then connect the pipeline 2 and the air pressure sensor 8 on the vacuum adsorption module, connect the air pressure sensor 8, the air pressure recorder 10, the pipeline valve controller 11 and the pipeline valve 3 with the wire 9; 2 is connected to the pipeline valve 3, and the other end is connected to the air pressure sensor 8. Each vacuum adsorption module connects the pipeline 2 of the pipeline valve 3 to the main pipeline 2 in parallel, and the main pipeline 2 is connected to the vacuum pump 1. After starting...

Description
technical field [0001] The invention belongs to the field of numerical control machining, and more specifically relates to a vacuum adsorption tooling for thin plate parts and a clamping method for numerical control machining of thin plate parts. Background technique [0002] In the process of CNC machining of aircraft structural parts, it is necessary to use tooling to achieve reliable positioning and clamping of parts, so as to ensure the processing quality of parts. For thin-plate aircraft structural parts, such as skins, wall panels and other parts, due to the thin thickness and large size of the parts, If you only use the pressure plate to compress the end, it will cause some areas of thin plate parts to warp. Therefore, for large-sized thin plate parts, it is necessary to use vacuum adsorption tooling to use air pressure to generate pressure on the thin plate. The lower surface is bonded to the upper surface of the tooling. [0003] Vacuum adsorption tooling is to set...
