Abstract
Machining blade is except a milling cutter for wet sump, and it relates to a kind of milling cutter, is specifically related to the milling cutter of a kind of machining blade except wet sump.The utility model utilizes disc wheel hand grinding in order to solve existing blade except wet sump by pincers worker, and not only working (machining) efficiency is low, and except wet sump linearity not ideal enough, affect the problem of effect on moisture extraction and presentation quality.The utility model comprises knife bar, cutter head and locking nut, the front end of knife bar is provided with screw rod, the lateral wall of screw rod is provided with positioning key, cutter head is made up of annulus and six blades, six blades are fixed on the lateral wall of annulus along the circumferencial direction of annulus is uniform, and the madial wall of annulus is provided with the locating slot matched with positioning key, and tool bit casing is contained on screw rod, positioning key is inserted in locating slot, is sleeved on screw rod for the locking nut of locking cutter head.The utility model is used in machining.
Description
Technical field
The utility model relates to a kind of milling cutter, is specifically related to the milling cutter of a kind of machining blade except wet sump, belongs to field of machining.
Background technology
Band is a kind of new structure type blade except wet sump turbine blade, has 5 ~ 8 except wet sump in blade convexity curved design, should be discharged, and to reduce moisture in cylinder, improved steam turbine operating efficiency except after wet sump cohesion steam by the tap of blade root.Utilize disc wheel hand grinding with the wet sump that removes of front vane by pincers worker, not only working (machining) efficiency is low, and it is not ideal enough to remove wet sump linearity, affects effect on moisture extraction and presentation quality.
Utility model content
The utility model utilizes disc wheel hand grinding for the existing blade of solution removes wet sump by pincers worker, not only working (machining) efficiency is low, and it is not ideal enough to remove wet sump linearity, affects the problem of effect on moisture extraction and presentation quality, and then the milling cutter of a kind of machining blade except wet sump is proposed.
The utility model be solve the problem adopt technical scheme be: the utility model comprises knife bar, cutter head and locking nut, the front end of knife bar is provided with screw rod, the lateral wall of screw rod is provided with positioning key, cutter head is made up of annulus and six blades, six blades are fixed on the lateral wall of annulus along the circumferencial direction of annulus is uniform, the madial wall of annulus is provided with the locating slot matched with positioning key, tool bit casing is contained on screw rod, positioning key is inserted in locating slot, is sleeved on screw rod for the locking nut of locking cutter head.
The beneficial effects of the utility model are: the utility model uses through reality, effect is fine, improve processing mode, be improved to CNC milling machine by hand grinding processing and utilize special-purpose milling cutter Milling Process, not only increase dehumidifying slot machining quality, and substantially increasing working (machining) efficiency, working (machining) efficiency is enhanced about more than once.This milling cutter adopts assembly structure pattern, when being only installed on knife bar by new milling cutter after cutter wear is scrapped, avoiding cutter entirety and scraps situation, saves tool expense.
