Problems solved by technology
However, beam flanges are large-scale aeronautical structural parts, and the size of their fixtures is correspondingly large. Based on the consideration of controlling processing deformation, a three-station vertical installation process is generally adopted (parts turn over twice). Three-station hydraulic fixtures for part design, the cost of the fixtures will be very high

The invention relates to a flexible clamp for numerical-control processing and application thereof in the technical field of mechanical engineering. The clamp comprises a plurality of connecting plate assemblies, positioning sections fixedly arranged at two ends of a lathe workbench and four public sections arranged between the two positioning sections, wherein the connecting plate assemblies arerespectively arranged between the positioning sections and the public sections and between the two public sections. The flexible clamp has the advantages of clamping automation, station compounding property and structure modularization and can be used for realizing positioning and clamping of beam edge strip parts with high speed, high reliability and high repeatability. Aiming at the special structure characteristics of the beam edge strip parts of airplanes, the flexible clamp has the characteristics that: a one-station clamp and a three-station clamp in the traditional three-station vertical installation are compounded into a whole, and the flexibility of simultaneously processing left and right symmetrical workpieces, of the clamp of each workpiece, is achieved at the same time of reducing the number of working stations of the clamp.
Description
technical field [0001] The invention relates to a device and application in the technical field of mechanical engineering, in particular to a flexible fixture for numerical control machining of large passenger aircraft girder flange parts and its application. Background technique [0002] In the manufacturing industry, manufacturing equipment and process equipment are regarded as the necessary hardware conditions to realize the principles of high product quality, high output and low consumption. Among them, as one of the most important process equipment, the fixture is the key link to realize the process route, ensure the processing quality, improve the production efficiency, reduce the processing cost and the labor intensity of the workers. As one of the typical high-tech fields in the manufacturing industry, the aviation manufacturing industry has put forward more stringent requirements for both manufacturing equipment and process equipment. Faced with the large-scale, co...
