Abstract

The invention provides a reconfigurable tooling for deformation test of thin-wall curved surface parts. The reconfigurable tooling comprises an installation rack, a plurality of displacement sensing assemblies, a curved surface part connecting assembly and an electric control assembly, wherein the installation rack comprises a bracket and a plurality of beams; two ends of each beam are arranged in the bracket through a sliding assembly; each displacement sensing assembly comprises a displacement sensor and a clamping assembly; and the curved surface part connecting assembly comprises a clamping plate, a long rod, a spherical hinge, two spherical hinge fixing blocks and a center alignment base. The reconfigurable tooling integrates locating, connection and measurement into a whole, participation of additional mechanical equipment is not needed, the operation is simple and convenient, the test has reconfigurability, displacement information can be timely fed back and the reconfigurable tooling can be applied to deformation measurement of different sizes of thin-wall curved surface parts; the displacement sensing assemblies are simple and small, and convenient to dismantle; through the arrangement of the spherical hinge, the defect that the displacement sensors cannot carry out angle rotation and direction deviation along with the measured positions is overcome and the displacement values of the measured points can be accurately obtained.

Description

technical field [0001] The invention relates to the technical field of deformation detection equipment for curved surface parts, in particular to a reconfigurable tooling for deformation testing of thin-walled curved surface parts. Background technique [0002] In aviation, aerospace and other fields, material forming, machining, mechanical assembly and other aspects of work, due to the limitations of technology, materials and other factors, the rigidity of the resulting product is small, and the size of the manufactured product has a certain deviation from the theoretical model, especially Especially in the field of aerospace, the size of the products it produces is very large, and most of the materials used are in pursuit of corrosion resistance, high temperature resistance, light weight, etc., so many materials are mostly composite materials, and their shapes are mostly thin-walled curved surfaces. The requirements for dimensional accuracy are very high, but in the proces...

Problems solved by technology

[0005] In order to solve the complex operation, difficult disassembly and small application range of existing displacement measurement devices, especially when measuring the displacement generated on the surface of thin-walled curved parts, the measured displacement direction cannot be accurately known, and the true direction of the specific direction cannot be obtained. Displacement value, such displacement data has no substantive effect on actual work, etc. The present invention provides a reconfigurable tooling for deformation testing of thin-walled curved surface parts that integrates positioning, connection and measurement.
