Fast feed milling cutter with improved structure

Abstract

The invention discloses a fast feed milling cutter with an improved structure, which comprises a cutter body, the cutter body is provided with a plurality of assembly grooves distributed in an annular array shape, and blades are embedded in the assembly grooves. A plurality of positioning columns which are distributed in an annular array shape and matched with the blades are embedded in the cutter body, a plurality of positioning grooves matched with the positioning columns are formed in the cutter body, the positioning columns are arranged in the positioning grooves, and the blades and the positioning columns are detachably connected through positioning bolts. According to the cutter, through mutual cooperation of a positioning column, a positioning groove and a positioning bolt, free disassembly of the blade can be achieved, the use effect of the cutter body is guaranteed to a certain extent through replacement of the blade, and meanwhile through mutual cooperation of a limiting ring, a limiting column, a spring, an adjusting column and a threaded column, the purpose of changing the milling depth of the blade is achieved; the practicability of the cutter body is further improved.

Description

technical field [0001] The invention relates to the technical field of milling tools, in particular to a fast-feed milling tool with an improved structure. Background technique [0002] When optimizing the milling effect, the blade of the milling tool is an important factor. In any milling, if more than one blade participates in cutting at the same time, it is an advantage, but too many blades participating in cutting at the same time is a disadvantage. When cutting, each It is impossible for the cutting edges to cut at the same time. The required power is related to the number of cutting edges participating in the cutting. In terms of chip formation process, cutting edge load and machining results, the position of the milling cutter relative to the workpiece plays an important role. In face milling, use a milling cutter that is about 30% larger than the cutting width and position the milling cutter close to the center of the workpiece, then the chip thickness does not chang...

Problems solved by technology

[0003] However, most of the existing one-piece cutter bodies or welded blades are used to process such workpieces. The cutting stability is insufficient, the blade steel is poor, and it is easy to damage and has no replaceability, resulting in high production costs and low product qualification rate. lower problem, for which a fast-feed milling tool with an improved structure is provided
