Linkage cluster type thin plate intelligent reconfigurable drilling clamp

Abstract

The invention discloses a linkage cluster type thin plate intelligent reconfigurable drilling clamp. The linkage cluster type thin plate intelligent reconfigurable drilling clamp comprises an angle sensor connected to a rotating platform connecting piece, a photoelectric displacement sensor installed on a rotating platform, a vacuum pressure sensor installed on a vacuum suction cup support, a data acquisition device and a PLC; the analysis decision part comprises a clamp layout analysis model and an optimization model in an upper computer; and the execution part comprises a rotary linkage clamping module. The linkage cluster type thin plate reconfigurable drilling clamp is suitable for clamping thin plates of various specifications, a positioning and clamping device is composed of a plurality of indexing type linkage mechanisms in a cluster mode, before drilling is conducted every time, a single indexing type linkage mechanism serves as a unit to conduct optimized adjustment of clamping layout, and the final quality of the thin plates after drilling is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of manufacturing equipment, and in particular relates to an intelligent reconfigurable hole-making jig for linkage cluster type thin plate parts. Background technique [0002] Thin-plate parts are widely used in aircraft, ship and other manufacturing industries due to their advantages of light weight and high strength, which can effectively improve product performance and reduce manufacturing costs. It is easy to deform under load, and it is difficult for traditional fixtures to control the deformation after making multiple holes in sequence to ensure machining accuracy. [0003] In order to limit the deformation of thin-plate parts after hole making, the current flexible hole-making fixtures often use the "N-2-1" over-constrained positioning method to clamp thin-plate parts. The spatial position coordinates of each positioning and clamping element are passed through the Although this type of fixture can po...

[0002] Thin-plate parts are widely used in aircraft, ship and other manufacturing industries due to their advantages of light weight and high strength, which can effectively improve product performance and reduce manufacturing costs. It is easy to deform under load, and it is difficult for traditional fixtures to control the deformation after making multiple holes in sequence to ensure machining accuracy

[0003] In order to limit the deformation of thin-plate parts after hole making, the current flexible hole-making fixtures often use the "N-2-1" over-constrained positioning method to clamp thin-plate parts. The spatial position coordinates of each positioning and clamping element are passed through the Although this type of fixture can position and clamp thin plate parts of different specifications within a certain range, a set of linear motion mechanisms are used to adjust the position of the fixture components in each direction, which is costly and complicated to control. Moreover, during the entire hole-making process, the fixture layout is not adjusted for different hole-making positions, so it is difficult to meet the process requirements after hole-making of thin-plate parts
