Description

A kind of milling cutter device with adjustable blade height function
Technical field
The present invention relates to the technical field of machining cutting tool, particularly a kind of milling cutter device with adjustable blade height function.
Background technology
Milling cutter device is comprised of cutter head and cutterhead, and cutter edge is sharp, cuts brisk.Milling cutter is the machine tool of standard, metal parts that can processing middle and high hardness and intensity also can be used for the processing of nonmetallic materials, in machining during the milling workpiece, normally the cutterhead with milling cutter is inserted on the machine tool chief axis, and machine tool chief axis drives milling cutter rotation milling workpiece.During milling, blade is drawn out easily or skids in cutterhead under the effect of cutting component.
Generally be provided with several blades at the cutterhead side face and be used for cutting workpiece on milling cutter device, during the cutterhead rotation, each blade will be milled into workpiece, guarantees that each blade is stressed evenly.
Yet, in practical operation, because the hardness of workpiece various piece and inhomogeneous, perhaps blade is beginning wearing and tearing under the milling for a long time, differ so that each blade stretches out the Partial Height of cutterhead, this is so that highly high blade is received more cutting force, and highly low blade does not then stress.This inhomogeneous stressed meeting brings burden to lathe, has reduced simultaneously the service life of milling cutter, and the machined surface smooth degree of workpiece descends.
In addition, when cutterhead is set on the machine tool chief axis, cutting force when the engaging power between the two needs greater than cutting workpiece, machine tool chief axis could be with the movable knife disc rotation like this, smooth cutting workpiece, if can carry out some designs to cutterhead, so that the power that engages between cutterhead and the machine tool chief axis increases, then this lathe can be used for cutting the workpiece of some ultrahigh hardness.
Summary of the invention
