Milling device suitable for high-speed plane finish milling

Abstract

The invention discloses a milling device suitable for high-speed plane finish milling. The milling device suitable for high-speed plane finish milling comprises a milling cutter plate, an adjustable vibration milling device and an online dynamic balance device, wherein the adjustable vibration milling device is mounted at the joint between a cutter handle and the milling cutter plate; the rear part of the online dynamic balance device is connected with a main shaft system of a milling machine; the front end of the online dynamic balance device is connected with the adjustable vibration milling device. By virtue of vibrators of the adjustable vibration milling device, feedback regulation is performed; an electric control hydraulic multi-way valve is used for controlling oil feeding amounts of different oil channels when the online dynamic balance device detects an unbalanced amount so as to achieve the dynamic balance during milling of a disc mill cuter, so that the purpose of high-speed and stable milling of the milling machine can be achieved; the stability during high-speed milling is ensured; the service life of a blade is prolonged.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a milling device for high-speed plane fine milling suitable for high-precision plane milling. Background technique [0002] In the field of machining, face milling has always been a very important cutting method. Some high-precision planes with high requirements and a key impact on product performance need to be formed by face milling. In some industries that require fine processing, especially in the auto parts processing industry, there are many demanding mating surfaces in some key core components (such as cylinder blocks and cylinder heads of automobile engines, etc.), these mating surfaces need to be used Face milling is used for processing and forming. Due to the large diameter of the face milling cutter head and the intermittent cutting during the processing, it is difficult to ensure the quality of the milled surface during normal processing. In order to en...

Problems solved by technology

In some industries that require fine processing, especially in the auto parts processing industry, there are many demanding mating surfaces in some key core components (such as cylinder blocks and cylinder heads of automobile engines, etc.), these mating surfaces need to be used Face milling is used for processing and forming. Due to the large diameter of the face milling cutter and the intermittent cutting during the processing, it is difficult to ensure the quality of the milled surface during normal processing.

In order to ensure the quality of the milling surface, most of the face milling cutters used for fine milling on the market have axial and radial adjustment devices to adjust the adaptability of the cutter head. Causes damage to the moving plane of the tool system

Therefore, the key problem restricting the development of high-speed precision face milling is still the cutting instability caused by the damage of the dynamic balance of the tool system during the face milling process and the impact of intermittent cutting impact on the tool life.
