The invention provides a composite material thin-walled piece clamp and a method for processing a composite material by using the clamp. The composite material thin-walled piece clamp comprises a clamp body, a vacuum sucking disk, a vacuum duct, a positioning mechanism and a liquid plastic tensioning mechanism, wherein the vacuum sucking disk is used for fixedly holding a workpiece, and is arranged on the side face of the clamp body; the vacuum duct is formed inside the clamp body; one end of the vacuum duct is connected with the vacuum sucking disk, and the other end of the vacuum duct is connected with a vacuum generator; the positioning mechanism is used for limiting the movement and the rotation of the workpiece, and is arranged on the side face of the clamp body; and the hydraulic plastic tensioning mechanism is used for supporting the workpiece and ensuring needed tension force output, and is arranged on the side face of the clamp body. Due to the adoption of the composite material thin-walled piece clamp and the method, the problems of insufficient rigidity and vibration in a workpiece machining process can be solved, the workpiece is prevented from deforming, the processing precision is increased, and the surface quality is improved.
Description
technical field [0001] The invention relates to the technical field of precision cutting of composite materials, in particular to a vacuum suction fixture and a method for processing workpieces using the fixture under high-speed milling conditions. Background technique [0002] Composite materials have the characteristics of low density, high strength and rigidity, temperature resistance, wear resistance, fatigue resistance, good damping performance, ablation resistance, radiation resistance, energy conversion and other physical functions. Therefore, composite materials have been used in construction , transportation, chemical industry, shipbuilding, aerospace and general machinery and other fields are widely used. [0003] Composite material is a typical difficult-to-process material. Its poor machinability leads to high processing costs, and its low processing efficiency makes its commercialization far from meeting people's expectations. Therefore, it is urgent to study ef...
