Abstract
The utility model discloses a numerically-controlled arc milling cutter which comprises a cutter handle, a cutter neck and a cutter bit, wherein a cutting edge of the cutter bit is composed of an arc cutting edge and linear cutting edges which are composited together, the arc cutting edge is arranged at the center of the cutter bit, the two sides of the arc cutting edge are tangentially transited to the linear cutting edges, the arc cutting edge and the linear cutting edges on both sides of the arc cutting edge define an open-type arc cutting edge structure, and an inclined angle formed by the extending lines of the linear cutting edges is greater than 90 degrees. The cutter disclosed by the utility model can effectively avoid the processing jumps of the surfaces of parts.
Description
Technical field
The utility model relates to the numerical control machining cutter field, particularly a kind of numerical control circular arc milling cutters of using to the processing of part sharp edge rounding more.
Background technology
In the digital control processing process, especially in some airplane parts digital control processings, the arc radius of some part sharp edge rounding is bigger, and the workload that the pincers worker file is repaiied these positions is too big, and quality also is difficult for guaranteeing, needs to adopt the arc cutter digital control processing to accomplish.
Existing arc cutter project organization is comparatively simple, and the general employing circular arc blade identical with part sharp edge arc radius accomplished digital control processing.The problem that exists is some little errors to occur when tool setting, when perhaps parts locally has micro-strain, can produce some tangible surperficial jumps when the part sharp edge processes, and influences surface quality.
Summary of the invention
The utility model has designed a kind of numerical control circular arc milling cutters of using to the processing of part sharp edge rounding more; This arc cutter is through the particular design of blade; Avoided some little errors occurring, the obvious surperficial jump that produces when perhaps parts locally has micro-strain when tool setting.
A kind of numerical control circular arc milling cutter; Contain cutter head; The blade that it is characterized in that cutter head is by the circular arc blade and the linear blade is compound forms, and the circular arc blade is positioned at the center, and the tangent transition in the both sides of circular arc blade is connected with the linear blade; The linear blade of circular arc blade and both sides constitutes an open curved blade structure, and the angle that linear blade extended line forms is greater than 90 degree.
The application's advantage is; Because blade is open arcuate structure; Two outboard ends of blade have increased the linear blade that has the inclination angle, have avoided because of some little errors appear in operator's tool setting the piece surface that produces when perhaps parts locally has micro-strain processing jump.
Below in conjunction with the embodiment accompanying drawing this application is described in further detail:
Description of drawings
Fig. 1 is the application's numerical control circular arc milling cutter construction signal
Fig. 2 is the application's numerical control circular arc milling cutter processing parts sharp edge circular arc signal
Numbering explanation among the figure: 1 handle of a knife, 2 cutter necks, 3 cutter heads, 4 circular arc blades, 5, linear blade, 6 top blade, 7 bottom blade, 8 milling cutters, 9 parts to be processed.
The specific embodiment
Referring to accompanying drawing, the application's numerical control circular arc milling cutter contains handle of a knife 1, cutter neck 2 and cutter head 3. its handle of a knifes 1 and is the retained part of arc cutter, and its diameter, length, precision are according to the milling handle standard design; Cutter neck 2 is the part that overhangs of arc cutter, connects handle of a knife 1 and cutter head 3, and its diameter, length are pressed the part to be processed structural design; Its cutter head 3 is the processing part of arc cutter; The blade of cutter head is an open arc structure; The core that is blade is a circular arc blade 4, and the two side portions of blade is a linear blade 5, linear blade 5 and circular arc blade 4 tangent seamlessly transitting; The linear blade 5 outside deflections of both sides, its line angle is greater than 90 °.
The numerical control circular arc milling cutter 8 that Fig. 1 embodiment provides is a kind of to aircraft wall plate parts T type muscle sharp edge rounding tool.Part to be processed 9 materials are aluminium alloy, and the sharp edge rounding of part to be processed 9 is 1mm.The diameter D1=Φ 20mm of handle of a knife 1, precision h6, length L 1=40mm.The diameter D2=Φ 18mm of cutter neck 2, length L 2=20mm.Ben is that cutter head 3 has upper and lower two groups of blades, and bottom blade 7 is used for the top sharp edge of processing parts, and top blade 6 is used for the bottom sharp edge of processing parts.Blade constitutes by three parts: the arc radius R1 of middle circle curved blade 4 equals processed sharp edge arc radius 1mm; The tangent linear blade 5 in circular arc blade 4 two ends is distinguished outside inclination angle A=5 °, and the line angle of linear blade reaches 100 ° like this, makes whole blade form an open arc structure, the length L 4=1mm of linear blade.Other position of cutter head is non-cutting tip, the diameter D3=Φ 32mm of cutter head, length L 3=20mm.
The disclosed cutter head of the application is that two groups of blades are integrated in one about having adopted, and therefore need not tool changing can accomplish sharp edge rounding processing up and down.
Claims (3)
1. numerical control circular arc milling cutter; Contain handle of a knife, cutter neck and cutter head; The blade that it is characterized in that cutter head is by the circular arc blade and the linear blade is compound forms, and the circular arc blade is positioned at the center, and the tangent transition in the both sides of circular arc blade is the linear blade; The linear blade of circular arc blade and both sides constitutes an open curved blade structure, and the angle that linear blade extended line forms is greater than 90 degree.
2. numerical control circular arc milling cutter as claimed in claim 1 is characterized in that described linear edegewise tilts about 5 °.
