Grinding and edge cutting device of composite material

Abstract

A grinding and edge cutting device of a composite material is composed of a casing connection part, a casing part, a power input part, a motion transformation part and a tool part. The casing connection part is located at the top of the device, the casing part is connected with a machine tool spindle casing through the casing connection part, the power input part is located between a machine tool spindle and a casing upper end cover, three transmission shafts of the motion transformation part are installed in the casing part through bearings, an input gear shaft of the motion transformation part is connected with the power input part through a coupling, output ends of two output gear shafts are used for being connected with a tool part and driving two tools to perform opposite rotation motion of the same size, and the tool part is located below a casing and fixed on two output gear shafts of the motion transformation part through a group of compression nuts. The grinding and edge cutting device of the composite material can be connected with a numerical control machine tool directly and is light and compact in structure, cutting grinding disks can rotate at the same speed synchronously, and accurate outline cutting can be performed on the upper surface and the lower surface of a carbon fiber reinforced composite material.

Description

technical field [0001] The invention relates to a composite material grinding and trimming device. The device applies the grinding method to the shape cutting of the composite material. Through the trimming device, the power of the electric spindle of the machine tool is transmitted to the tool part to achieve efficient and efficient carbon fiber reinforced composite materials. A method and device for high-quality grinding and trimming. It belongs to the technical field of composite material processing. Background technique [0002] Carbon fiber composite materials, especially high-performance and high-temperature-resistant carbon fiber composite materials, are more and more widely used in the aviation field due to their excellent performance, structural designability, weight reduction, and long life. However, with the current popular and conventional manufacturing processes: vacuum bag-autoclave method, liquid molding method, etc., there are edge effects in the parts produ...

AI Technical Summary

Problems solved by technology

Since both diamond and carbide can withstand the wear of various carbon fiber laminate composites, specially modified polycrystalline diamond (PCD) welded or diamond-coated tips have the longest tool life, but the cost Quite high, usually cemented carbide tools are still used in actual production

However, whether it is a diamond tool or a cemented carbide tool, there are delamination defects in the processed section.
