Abstract

The invention relates to a trimming and chamfering tool for a composite material laminated structure, and belongs to the technical field of trimming tools. The technical problem that in the trimming and chamfering process of a composite material laminated structure in the prior art, layering is likely to happen in the machining process, and the manual machining efficiency and precision are low is solved. The trimming and chamfering tool for the composite material laminated structure comprises a tool handle part and a tool bit part, wherein the tool handle part comprises a tool handle; the tool bit part comprises a connecting piece and N tool bits, and N is larger than or equal to 2; and the connecting piece is fixedly connected with the tool handle, one end of each tool bit is fixedly connected with the connecting piece, the other end of each tool bit is provided with a tool edge parallel to the axial direction of the tool handle, V-shaped grooves are formed in the tool bits, groove openings of the V-shaped grooves are located in the tool edges, and symmetrical surfaces of the V-shaped grooves are perpendicular to the axial direction of the tool handle. The special trimming and chamfering tool for the composite material laminated structure cannot causing the layering of the composite material laminated structure.

Description

technical field [0001] The invention belongs to the technical field of edge trimming tools, and in particular relates to an edge trimming and chamfering tool for a composite material laminated structure. Background technique [0002] The laminated structure of composite materials has the advantages of low density, excellent physical and mechanical properties and mechanical properties, and has a wide range of applications in the aerospace field. [0003] However, due to the weak interlayer strength (tens of MPa) of the laminated structure of composite materials, the machining process easily leads to delamination of the laminated structure. Especially in the trimming and chamfering process, the existing tool (milling cutter or grinding head) will squeeze the composite material when the machine tool is fed, which will easily lead to the delamination of the composite material. Therefore, the edge trimming and chamfering of the existing composite material laminated structure are...
