Milling tools with anti-fly function

Abstract

The invention discloses a milling tool with anti-flying function, which comprises a disc-shaped cutter body and a cutting unit arranged on the periphery of the disc-shaped cutter body. The ring-shaped anti-fly sleeve that flies away from the disc-shaped cutter body is provided with a pressing piece for pressing the cutting unit at the corresponding position of the ring-shaped anti-fly sleeve. The milling tool has the advantages of simple and stable structure, can prevent chips from being scratched, and can prolong the service life.

Description

technical field [0001] The invention mainly relates to the technical field of metal cutting, in particular to a milling tool with anti-flying function. Background technique [0002] With the advancement of machine tools and cutting technology, milling cutters equipped with welded PCD tool holders are widely used in high-speed milling of aluminum alloys. These tools generally have the following characteristics: 1. The cutting tool holders are arranged on the periphery of the disc-shaped cutter body. In the open tool slot, the clamping screw of the tool holder passes through the hole on the tool holder to compress the tool holder and is directly connected to the cutter body. The adjustment structure is located at the bottom of the tool holder and directly contacts or connects with the cutter body; 2. The cutter body The aluminum alloy itself is used to meet the requirements of high-speed rotation. [0003] This type of tool in the prior art has the following problems: 1. The ...

AI Technical Summary

Problems solved by technology

[0003] This type of tool in the prior art has the following problems: 1. The tool holder is arranged in the open knife groove on the periphery of the cutter body, which means that when the pressing structure fails, when the tool rotates at high speed, the tool holder, The compression screw and the adjustment structure may fly out of the cutter body under the action of centrifugal force; 2. The direct connection between the compression screw and the aluminum alloy cutter body results in limited connection strength, and there is a possibility of failure during high-speed processing; 3. Adjustment The structure is in direct contact or connection with the aluminum alloy cutter body, which is likely to cause wear of the cutter body during repeated adjustments, affecting the contact accuracy or strength between the adjustment structure and the cutter body; They are independent of each other and lack a unified axial positioning reference, which leads to a large difference in the initial axial position of each tool holder, which means that the adjustment time increases; 5. The tool body is made of aluminum alloy and has no peripheral protection, which is easy to be chipped during cutting scratch
