Honeycomb core material milling cutter

Abstract

The invention discloses a honeycomb core material milling cutter which comprises a cutter holder, a disk saw blade, a gasket and a fastening bolt, wherein a horn-shaped blade connection section is arranged at the front section of the cutter holder, a rod-shaped clamping section is arranged at the rear section of the cutter holder, the disk saw blade is in fit with an end face of the blade connection section, the gasket is in fit with the disk saw blade, and the fastening bolt sequentially penetrates through the gasket, the disk saw blade and the blade connection section to be fixed. The honeycomb core material milling cutter has the advantages that the shape and the structure of the cutter holder are subversively changed, so that the diameter of the milling cutter can be obviously increased, the chamfering size is obviously increased, a honeycomb core which is larger in thickness can be cut and chamfered, and a cutting area is enlarged; a assembling contact area between the cutter holder and the milling cutter is obviously enlarged, so that the stability and the dynamic balance performance of the whole cutter are obviously improved, and the safety and the durability of the cutter are improved; the disk saw blade can deform when being used, so that the central position of the blade is prevented from being in contact with the honeycomb core, only the edge of the blade is utilized to cut the honeycomb core, the cutting force is increased, the friction is reduced, the machining efficiency is improved, and the blade is protected through multiple structural designs; the cutter is quick and convenient to assemble and connect.

Description

technical field [0001] The invention relates to a milling tool, in particular to a tool for milling honeycomb core raw materials. Background technique [0002] Composite honeycomb sandwich structure has been widely used in many fields such as aviation and aerospace, and the honeycomb core raw material needs to be processed into a shape that meets the requirements during production. At present, conventional edge-tooth milling cutters and sheet milling cutters are mainly used. The milling cutter is assembled with the tool holder, and the honeycomb core is milled and chamfered by high-speed rotation. [0003] However, there are some shortcomings in the existing milling cutter cutting: 1. The diameter of the conventional milling cutter is very small, so the size of the honeycomb core material for milling is limited; 2. Because the shape of the cutter bar is columnar, the diameter of the milling cutter is very small, and The milling cutter and the cylindrical tool holder are coa...

Problems solved by technology

[0003] However, there are some shortcomings in the existing milling cutter cutting: 1. The diameter of the conventional milling cutter is very small, so the size of the honeycomb core material for milling is limited; 2. Because the shape of the cutter bar is columnar, the diameter of the milling cutter is very small, and The milling cutter and the cylindrical tool holder are coaxially installed on the length. Due to the limitation of the assembly structure, the overall slender structure has poor dynamic balance when rotating at high speed; 3. At high speed, the safety factor is low, and the milling cutter Badly worn
