An Intelligent Reconfigurable Riveting Fixture for Turning Thin Plate Parts

Abstract

The invention discloses an intelligent and reconfigurable riveting fixture for flip-type thin plate parts, which is mainly used for clamping thin plate parts for drilling and riveting operations. This intelligent tooling mainly includes a multi-point flexible flip tooling mechanical body, a sensing module and a control module. The skin is clamped mainly through the N-2-1 positioning method, and the actual position of the ball head is positioned by the cable displacement sensor equipped with the electric cylinder. , the load cell and the vacuum pressure sensor feed back the actual positioning point contact force and clamping force, and the angle sensor detects the actual flip angle of the flip table; the controller collects the actual clamping layout information through the data acquisition module, and communicates with the upper computer input The optimal clamping layout data is analyzed and decided, and the instructions from the controller are executed by the electric cylinder and air pump to adjust the position of the tooling and the clamping force. This intelligent reconfigurable flip tool is suitable for riveting of thin plate parts of different sizes and curvatures, and can adjust the clamping layout in the processing gap for different hole making and riveting positions, effectively ensuring product quality.

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
