Compression roller mechanism suitable for curved surface laying of composite material

Abstract

The invention relates to a compression roller mechanism suitable for curved surface laying of a composite material. The compression roller mechanism comprises independent pneumatic compression rollermechanism bodies, and the upper ends and the lower ends of cylinder barrels of pneumatic cylinders in the independent compression roller mechanism bodies are connected with an upper air cylinder baseand a lower air cylinder base respectively; the left ends and the right ends of the upper air cylinder base and the lower air cylinder base are connected with a left rack and a right rack respectively; and compression roller bases are connected with cylinder rods of the pneumatic cylinders, compression rollers are driven to move up and down through stretching and retracting of the cylinder rods ofthe pneumatic cylinders, composite material laying of curved surfaces with different curvatures can be adapted, and pressure control in the laying process is achieved through the pneumatic cylinders.The compression roller mechanism is provided with the multiple independent pneumatic compression roller mechanism bodies, the stretching amount and pressure of the pneumatic cylinder in each independent pneumatic compression roller mechanism can be independently controlled, and therefore composite material laying of multiple track curved surfaces can be completed at a time, the laying efficiencyis greatly improved, and the laying quality is guaranteed.

Description

technical field [0001] The invention belongs to the automatic tape laying equipment technology of composite materials, and relates to a pressure roller mechanism suitable for laying composite materials on curved surfaces. Background technique [0002] Composite materials have the characteristics of two or more materials, such as light weight and high strength, and also have good designability. The corresponding mold can be prepared according to the shape of the required parts, and the composite material can be laid on the mold. Can be made into required part shape. [0003] For the laying of flat composite materials, a single pressing roller of a certain width can be directly used to complete the laying of composite materials of a certain width in one laying. However, when performing automatic placement of composite materials on curved surfaces, due to the differences and changes in the curvature of the curved surfaces, it is extremely difficult for the automatic placement ...

Problems solved by technology

However, when performing automatic placement of composite materials on curved surfaces, due to the differences and changes in the curvature of curved surfaces, it is extremely difficult for the automatic placement device to place composite materials on curved surfaces, thus limiting the shape of parts formed by automatic placement of composite materials

If laying adopts manual laying of composite materials on the curved surface, when the required laying area is large, the efficiency of manual laying is low and the laying quality is difficult to guarantee. One of the important problems that need to be solved urgently in the application process
