Detailed Description
Reference will now be made in detail to the present preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout.
In the present invention, if directions (up, down, left, right, front, and rear) are described, it is only for convenience of describing the technical solution of the present invention, and it is not intended or implied that the technical features referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, it is not to be construed as limiting the present invention.
In the utility model, the meaning of "a plurality" is one or more, the meaning of "a plurality" is more than two, and the terms of "more than", "less than", "more than" and the like are understood to exclude the number; the terms "above", "below", "within" and the like are understood to include the instant numbers. In the description of the present invention, if there is description of "first" and "second" only for the purpose of distinguishing technical features, it is not to be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features or implicitly indicating the precedence of the indicated technical features.
In the present invention, unless otherwise specifically limited, the terms "disposed," "mounted," "connected," and the like are to be understood in a broad sense, and for example, may be directly connected or indirectly connected through an intermediate; can be fixedly connected, can also be detachably connected and can also be integrally formed; may be mechanically coupled, may be electrically coupled or may be capable of communicating with each other; either as communication within the two elements or as an interactive relationship of the two elements. The specific meaning of the above-mentioned words in the present invention can be reasonably determined by those skilled in the art in combination with the detailed contents of the technical solutions.
Referring to fig. 1 to 3, the present invention provides a milling cutter, which comprises a shank 1 and a cutting part 2, wherein the cutting part 2 is connected to one end of the shank 1, the cutting part 2 comprises a plurality of cutting edges 20, each cutting edge 20 spirally extends along the axial direction of the shank 1 and is distributed at intervals along the circumferential direction of the shank 1, and the intervals between the cutting edges 20 are different.
Because the interval between every cutting edge 20 is inequality, so the resonance that produces can avoid every cutting edge 20 and the same cycle of work piece contact in the milling cutter rotation process to effectively restrain the tremble that the processing produced, improve the processingquality of product, improve the life of cutter.
The cutting edge 20 of the present invention extends spirally along the axial direction of the shank 1, so that the contact length between the cutting edge 20 and the workpiece can be effectively reduced, and the cutting resistance can be reduced.
The cutting portion 2 further comprises an end edge 21, the end edge 21 being connected to the end of each cutting edge 20 remote from the shank portion 1.
In the present invention, the end blade 21 has a circular arc-shaped configuration.
In other embodiments, the cutting part 2 is in a cone-shaped ball head structure, so that the radian of the cutting edge 20 which is a spiral arc and protrudes outwards is longer, and in the processing process, the processing paths of the cutting edge 20 on products with the same area are fewer, so that the processing efficiency can be effectively improved.
In addition, the cutting edge of the cutting edge 20 of the cutting part 2 with the spindle-shaped ball head structure can be conveniently changed in the rough machining and finish machining processes, as shown in fig. 4 and 5, the cutting edge 20 of different sections can cut workpieces by rotating the swing angle of the milling cutter, and therefore the rough machining and the finish machining can be switched.
In some embodiments, a connecting rod 3 is provided between the shank 1 and the cutting portion 2.
In the present invention, the connecting rod 3 is a tapered rod.
Specifically, the radius of the connecting rod 3 gradually decreases in the direction from the shank portion 1 to the cutting portion 2, and a step is provided between the connecting rod 3 and the shank portion 1.
In other embodiments, the cutting edge 20 is connected to the shank 1 by a transition cutting edge 22.
Referring to fig. 2, the radius of the arc c tangent to the points a and b is 3 times the radius of the arc of the end edge of the section d, specifically, the point a is the junction of the cutting edge 20 and the end edge 21, the point b is the junction of the adjacent cutting edge 20 and the corresponding transition cutting edge 22, and the section d is the arc formed by the end edges 21 of the two opposite cutting edges 20.
Of course, the present invention is not limited to the above embodiments, and those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the present invention, and such equivalent modifications or substitutions are included in the scope defined by the claims of the present application.
