Turnover type intelligent reconfigurable riveting clamp for thin plate parts

Abstract

The invention discloses a turnover type intelligent reconfigurable riveting clamp for thin plate parts. The turnover type intelligent reconfigurable riveting clamp is mainly used for clamping the thinplate part for drilling and riveting operation. The turnover type intelligent reconfigurable riveting clamp mainly comprises a multi-point flexible turnover tool mechanical body, a sensing module anda control module, clamping is carried out on a skin mainly in an N-2-1 positioning mode, the actual position of a positioning ball head is fed back through a stay wire displacement sensor assembled on an electric cylinder, a force measuring sensor and a vacuum pressure sensor feed back actual positioning point contact force and clamping force, an angle sensor detects the actual overturning angleof an overturning workbench, a controller collects actual clamping layout information through the data collection module, the actual clamping layout information and optimal clamping layout data inputby an upper computer are analyzed and decided, instructions from the controller are executed by the electric cylinder and an air pump, and adjusting is carried out on the tool position and the clamping force. The turnover type intelligent reconfigurable riveting clamp is suitable for riveting thin plate parts with different sizes and curvatures, the clamping layout can be adjusted in the machininggap according to different hole forming and riveting positions, and the product quality is effectively guaranteed.

Description

technical field [0001] The invention belongs to the technical field of tooling equipment, and in particular relates to an intelligent reconfigurable riveting jig for flip-type thin plate parts. Background technique [0002] Aerospace, shipbuilding and automobile manufacturing are important industries in my country's economy. There are a large number of thin plate parts with the characteristics of light weight and easy shape, which ensure that the products have good aerodynamic characteristics. However, the rigidity of the larger thin-plate parts is poor, and the hole-making riveting assembly is required, so it is difficult to guarantee the processing requirements. [0003] The traditional drilling and riveting tooling for curved thin-plate parts mostly adopts a rigid structure, and realizes the positioning and clamping of various types and specifications of curved-surface thin-plate parts through clamping plates, which requires the manufacture of a variety of large-scale fix...

Problems solved by technology

And because most of the tooling needs to manually adjust the positioning and clamping elements during the entire manufacturing process, it cannot meet the higher process requirements of the product, and the efficiency is low

On the other hand, due to processing conditions and space constraints, curved thin-plate parts often require two states, horizontal and vertical, but the current fixture does not have this function
