Abstract

The special corn milling cutter that the utility model discloses a kind of machining crankshafts, it comprises composite blade and handle of a knife, it is characterized in that 90 °, described handle of a knife head is uniformly distributed four U-shaped grooves, four composite blades are uniformly distributed on four U-shaped grooves.Described composite blade adopts YG8 alloy material.The utility model processing axle journal axle journal is when milling journal surface needs allowance, can process the surplus of fan-shaped two sides, step cylindrical that can disposable processing axle journal two sides, because self-control special plane is that primary feed can be processed four axle journals, working (machining) efficiency is high simultaneously, and it is more even that handle of a knife head fills four composite blade wearing and tearing, in actual process, cutter loss is less, composite blade adopts YG8 alloy material, has increased service life, is applicable to machining crankshafts axle journal and side simultaneously.

Description

A kind of special corn milling cutter of machining crankshafts
Technical field
The utility model relates to Crankshaft Machining field, particularly a kind of special corn milling cutter of machining crankshafts.
Background technology
Bent axle belongs to the standard fitting of parts industry, and crankshaft processing technology is loaded down with trivial details, and tooling step is more.In traditional crankshaft processing technology, axle journal processing is mainly divided into rough turn axle journal, and mao mill axle journal partly refines axle journal and fine grinding axle journal, and wherein hair grinds and partly refines processing technology between each manufacturer and respectively has any different.Rough turn axle journal is the first step of axle journal processing, the black skin that its initial approaching side is crankshaft journal, chipping allowance is large, when blank material is not when being very desirable, case hardness gap is larger, easily causes and collapses cutter phenomenon, and cutter consumption is also larger, the processes requirements such as part bent axle also needs to process the step of axle journal two sides, the fan-shaped side of bent axle.Meanwhile, no matter be the rough turn axle journal cylindrical of lathe or cylindrical grinder hair mill axle journal cylindrical, be all processing of an axle journal of an axle journal, cause bent axle single track operation longer process time, these practical problems such as be difficult to enhance productivity.
Utility model content
Technical problem to be solved in the utility model is to overcome the defect that above-mentioned prior art exists, and provides that a kind of working (machining) efficiency is high, tool wear is little and the special corn milling cutter of the machining crankshafts of long service life.
For achieving the above object, the utility model adopts following technical scheme: a kind of special corn milling cutter of machining crankshafts, it comprises composite blade and handle of a knife, it is characterized in that 90 °, described handle of a knife head is uniformly distributed four U-shaped grooves, and four composite blades are uniformly distributed on four U-shaped grooves.Described composite blade adopts YG8 alloy material.
The beneficial effects of the utility model are: special corn milling cutter processing axle journal axle journal is when milling journal surface needs allowance, can process the surplus of fan-shaped two sides, step cylindrical that can disposable processing axle journal two sides, simultaneously because self-control special plane is that primary feed can be processed four axle journals, working (machining) efficiency is high, and it is more even that handle of a knife head fills four composite blade wearing and tearing, and in actual process, cutter loss is less, composite blade adopts YG8 alloy material, has increased service life.
Brief description of the drawings
Fig. 1 is structural front view of the present utility model;
Fig. 2 is structure left view of the present utility model;
Fig. 3 is specifically enforcement figure of the utility model.
In figure, 1-composite blade, 2-handle of a knife, 3-U type groove.
Detailed description of the invention
The special corn milling cutter of a kind of machining crankshafts as shown in Figure 1 to Figure 3, it comprises composite blade 1 and handle of a knife 2, first milling out four U-shaped grooves 3 at handle of a knife 2 heads is 90 ° and is uniformly distributed, then adopt solder technology that four composite blades 1 of YG8 alloy material are welded on U-shaped groove 3 successively, make special corn milling cutter processing axle journal axle journal when milling journal surface needs allowance, can process the surplus of fan-shaped two sides, step cylindrical that can disposable processing axle journal two sides, simultaneously because self-control special plane is that primary feed can be processed four axle journals, working (machining) efficiency is high, handle of a knife 2 heads fill four composite blades 1 and wear and tear more even, in actual process, cutter loss is less, composite blade 1 adopts YG8 alloy material, increase service life.
