'Pineapple-shaped' milling cutter applicable to high-speed machining for end surface, side surface and inclined surface in situ

Abstract

The invention provides a 'pineapple-shaped' milling cutter applicable to high-speed machining for an end surface, a side surface and an inclined surface in situ. The milling cutter comprises a milling cutter collet and a cutter blade, and the cutter blade comprises at least one milling cutter side cutter body, wherein the milling cutter side cutter body and the milling cutter collet are coaxially installed and integrally installed on a machining center spindle at the periphery; at least one spiral groove and at least one stepped groove are machined in the outer surface of the milling cutter side cutter body, the positions of the spiral groove and the stepped groove are adjacent, and a side surface blade is installed on a stepped surface of the stepped groove and corresponds to the position of the spiral groove; an arc-shaped groove corresponding to the positions of the spiral groove and the stepped groove is machined in the side surface of the milling cutter collet, at least one inclined surface blade is also arranged on the side surface of the milling cutter collet, and at least one end surface blade is arranged on the bottom surface of the milling cutter collet; and the end surface blade, the side surface blade and the inclined surface blade respectively act on the end surface, the side surface and the inclined surface of a workpiece. The 'pineapple-shaped' milling cutter provided by the invention can achieve efficient machining for the end surface, the side surface and the inclined surface of the workpiece without replacing the cutter or a tool.

Description

technical field [0001] The invention relates to a milling cutter, in particular to a "pineapple-shaped" milling cutter suitable for in-situ high-speed cutting on three sides of an end side, and belongs to the technical field of high-speed cutting. Background technique [0002] High-speed cutting is one of the mainstream technologies for material removal and an important part of the equipment manufacturing industry that is related to the national economic base. High-speed cutting mainly includes machine tool equipment and process technology, and tool technology is an important component of process technology. The tool is the medium and carrier for the equipment and process performance of the machining center, and has always played the role of precision and high-tech content. [0003] Milling tools are the majority of tools used in machining centers, but the milling tools in machining centers are generally small in diameter and cannot convert the high rotational speed of the ...

AI Technical Summary

Problems solved by technology

[0003] Milling tools are the majority of tools used in machining centers, but the diameter of milling tools in machining centers is generally small, which cannot convert the high rotational speed of the machine tool into high linear speed, which limits the cutting efficiency and cutting quality of the machining center to a certain extent

On the other hand, commonly used milling cutters, such as end mills, cylindrical mills, end mills, etc., can only process one side. For the occasion where the end face, side face and inclined plane of the workpiece coexist, it needs to be changed continuously. It can only be solved by changing the tool or changing the workpiece clamping, which affects the cutting efficiency or cutting accuracy
