Abstract
The invention discloses a milling cutter which comprises a fixed end and a cutter body, wherein the fixed end is positioned above the cutter body and is connected with the cutter body; the cutter body is cylindrical, and a bottom surface of the cutter body is a diagonal plane; a blade mounting hole is formed in a circumference surface of the cutter body and is parallel to the bottom surface of the cutter body; the orifice of the blade mounting hole is inclined downwards; a screw hole is formed in the circumference surface of the cutter body and is communicated with the blade mounting hole; a bolt is arranged on the screw hole; a spring is arranged at the hole bottom, which is positioned in the cutter body, of the blade mounting hole; a blade is arranged in the blade mounting hole; one end of the blade is connected with the spring, and the other end of the blade extends out of the orifice of the blade mounting hole; the blade is fixed in the blade mounting hole by screwing the bolt. The milling cutter is simple in structure and can be protected, and a workpiece can be prevented from being damaged.
Description
Technical field
The present invention relates to a kind of milling cutter.
Background technology
Milling cutter is most important machining tool in Milling Process, after being generally mounted on lathe, workpiece is processed to use, the blade of some milling cutter and cutter hub are not integral types, in processing use procedure, blade likely can become flexible, cause blade and the location of workpiece to be related to change, blade and workpiece are all damaged.
Summary of the invention
Goal of the invention of the present invention is: for the problem of above-mentioned existence, provide a kind of simple in structure, the milling cutter that can protect milling cutter can protect workpiece not to be damaged again.
The technical solution used in the present invention is such: a kind of milling cutter, comprise stiff end and cutter hub, described stiff end is positioned at cutter hub top, be connected with cutter hub, described cutter hub is cylindrical, bottom surface is a scarf, the periphery of described cutter hub is provided with a blade installing hole, described blade installing hole is parallel with cutter hub bottom surface, under the aperture of blade installing hole is oblique, on the periphery of described cutter hub, be also provided with a screw, screw is communicated with blade installing hole, on screw, be provided with bolt, described blade mounting hole site is provided with a spring at the bottom of the hole in cutter hub, in blade installing hole, be provided with blade, blade one end is connected with spring, the other end stretches out from the aperture of blade installing hole, by tighting a bolt, blade is fixed in blade installing hole.
In sum, owing to having adopted technique scheme, the invention has the beneficial effects as follows:
1, simple in structure, can protect milling cutter can protect again workpiece not to be damaged.
Accompanying drawing explanation
Fig. 1 is front view of the present invention.
Fig. 2 is cutaway view of the present invention.
Mark in figure: 1 is stiff end, 2, cutter hub, 3, blade installing hole, 4, screw, 5, bolt, 6, spring, 7, blade.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
As Fig. 1, shown in Fig. 2, a kind of milling cutter, comprise stiff end 1 and cutter hub 2, described stiff end 1 is positioned at cutter hub 2 tops, be connected with cutter hub 2, described cutter hub 2 is cylindrical, bottom surface is a scarf, the periphery of described cutter hub 2 is provided with a blade installing hole 3, described blade installing hole 3 is parallel with cutter hub 2 bottom surfaces, under the aperture of blade installing hole 3 is oblique, on the periphery of described cutter hub 2, be also provided with a screw 4, screw 4 is communicated with blade installing hole 3, on screw 4, be provided with bolt 5, described blade installing hole 3 is provided with a spring 6 at the bottom of being positioned at the hole of cutter hub 2, in blade installing hole 3, be provided with blade 7, blade 7 one end are connected with spring 6, the other end stretches out from the aperture of blade installing hole 3, by tighting a bolt, 5 blade 7 is fixed in blade installing hole 3.Once bolt 5 occurs loosening, blade is fixing not tight, and blade 7 can be subject to the restoring force of spring 6, makes blade 7 to the interior contraction of blade installing hole 3, and thus, blade 7 and will standing away at the workpiece of processing, has protected blade 7 and workpiece injury-free.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
