Abstract

The invention discloses a multipoint profiling rigid clamp, comprising a clamp body. The clamp body is provided with a positioning surface for positioning a processed workpiece; the positioning surface is provided with a vacuum sucker; the clamp body is internally provided with a vacuum hole channel; one end of the vacuum hole channel is connected with the vacuum sucker, and the other end of the vacuum hole channel is connected with a vacuum valve island arranged at the outer part of the clamp body; the vacuum valve island is connected with a vacuum system connected with a control system; andthe vacuum hole channel is also connected with the control system by a vacuum sensor. A method for processing a thin-wall workpiece by using the multipoint profiling rigid clamp comprises the steps of: modeling, analyzing, determining and optimizing key positioning points, arranging the vacuum sucker, processing the positioning surface of the clamping body and finally carrying out processing on the thin-wall workpiece. The multipoint profiling rigid clamp is used for a high-speed milling finish processing stage of the complex profile of the thin-wall workpiece, the positioning surface of the clamp is consistent to the surface type of the processed workpiece, the uniform distribution of a clamping force is guaranteed and the clamping and the deformation of the thin-wall workpiece are avoided.

Description

technical field [0001] The invention relates to the precision cutting processing technology of composite material thin-walled parts, in particular to a multi-point profiling rigid fixture and a method for using the fixture to process thin-walled workpieces under high-speed milling conditions. Background technique [0002] Advanced composite materials (ACM) are widely used in aviation, aerospace, automobile, medicine and other fields due to their high specific strength, high specific modulus and low thermal expansion coefficient. At the same time, the use of two-dimensional weaving, three-dimensional overall weaving, local reinforcement and filling can effectively ensure the reliable transmission of loads and the smooth transition of rigidity, so that materials and structures can be fully utilized. Therefore, composite materials have become the fourth largest aeronautical structural materials that have risen rapidly after aluminum, steel, and titanium. Ceramic matrix compo...
