Description
Technical field
This utility model patent is related to machining production field, particularly to a kind of milling cutter.
Background technology
With the continuous progress and development of industrial science technology, mechanical processing industry is to high accuracy, high efficiency, height automatically
The direction changed is developed, and this undoubtedly puts forward higher requirement to the processing characteristics and stability of Digit Control Machine Tool, overall with product
Change, light-weight design and the continuous lifting to aerodynamic performance requirements, increasing complex free curved surface occurs in aviation boat
My god, in the part of product such as automobile and ship, because these complex-curved geometric propertieses are complicated, Curvature varying is big.
Currently for some, there is the workpiece in back-off inner mold face, added with existing three axles, four axles and five- sided machining center
Work generally requires parts design special fixture is carried out to it secondary or multiple clamping and can complete to process, but parts pass through
Repeatedly conversion clamping easily produces cumulative error, and dimensional accuracy is difficult to ensure, and the precision processed is not high.Traditionally design one
Determine the frock clamp of gradient, make part back-off position be applied to three axle lathes in angle of release and be processed, or joined with five-axis machine tool
The method closing mill principal axis pivot angle machining is processed.
In prior art, on three axle lathes processing have back-off inner mold face workpiece very inconvenient, need part is entered
To complete to process, when processing workpiece, the positioning relation of workpiece changes this processing mode row multiple clamping, Working position
Relativeness be not easy to ensure easily overproof phenomenon occurs, and processing cost is very high on five-axis machine tool, lack economic effect
Benefit.
Utility model content
Technical problem to be solved in the utility model and the technical assignment proposing are that prior art is improved, and provide
A kind of milling cutter, it is intended that realized in three axle machine tooling back-off class workpiece by this milling cutter.
For solving above technical problem, the technical solution of the utility model is, a kind of milling cutter, and including knife bar, blade is fixed
On knife bar, the circumference of described blade end is provided with cutter tooth, described cutter tooth is more than in the radius of clean-up away from knife bar side
Radius of clean-up near knife bar side.
Preferably, the minimum radius of clean-up of described cutter tooth is more than blade radius and knife bar radius.
Preferably, described cutter tooth has the cutting profile of circular arc away from knife bar side.
Preferably, the quantity of described cutter tooth is even number.
Preferably, described blade is provided with dregs guiding groove between adjacent cutter tooth.
According to this utility model, a kind of milling cutter, for processing back-off class workpiece, back-off class workpiece is side in vertical direction
Wall has a class groove shape workpiece of projection in bottom surface.
According to this utility model, the circumference of blade end is provided with cutter tooth, and cutter tooth is up-narrow and down-wide structure, and that is, cutter tooth exists
Radius of clean-up away from knife bar side is more than the radius of clean-up of close knife bar side, and the minimum radius of clean-up of cutter tooth is more than knife
Body radius and knife bar radius, can avoid the situation that cannot process cell body because of the stop of side wall upper part or tilt groove face, pass through
Described milling cutter, can complete the processing to back-off class workpiece cell body by clamped one time, it is to avoid three axle lathes need repeatedly to fill
Folder just can complete the processing problems of back-off class workpiece, improve working (machining) efficiency and machining accuracy, avoid in five-axis machine tool simultaneously
Upper processing back-off part high processing costs, the problem of deficiency in economic performance.
Cutter tooth has the cutting profile of circular arc in the side away from knife bar, goes between cell body bottom and side wall
The processing of rounding needs.
Blade is provided with dregs guiding groove between adjacent cutter tooth, convenient discharge chip.
According to this utility model, this utility model provides a kind of milling cutter, and by installing this milling cutter, three axle lathes can achieve and add
Work back-off class workpiece, this utility model has processing simply, the advantage increased economic efficiency.
