Description
Technical field
The present invention relates to and a kind ofly clamp firm milling cutter, belong to cutting-tool engineering field.
Background technology
Milling cutter is for Milling Process, the rotary cutter with one or more cutter tooth.During work, each cutter tooth cuts the surplus of workpiece successively off and on.Milling cutter is mainly used in processing plane, step, groove, profiled surface and cut-out workpiece etc. on milling machine.
Milling cutter is applied extremely wide in Milling Process, and existing milling cutter is made up of cutter hub and the blade be fixed on the fixed part of cutter hub usually, can cannot continue because wearing and tearing shorten to use after blade uses a period of time.Therefore, in Milling Process, need often to change the blade shortened because of wearing and tearing, so, cutter use cost is sharply increased.
In addition, existing milling cutter is not generally collected in the function of the chip produced in milling process, and knife bar clamps not strongly solid on chucking device, easily rocks, causes machining accuracy to reduce.
Summary of the invention
Technical problem to be solved by this invention is, provides the milling cutter that the adjustable clamping of a kind of blade lengths is firm; Further, the milling cutter providing a kind of blade fixed; Further, a kind of milling cutter with collection of debris function is provided; Further, provide a kind of arbor holder to keep steady solid, knife bar not easily rocks, the milling cutter that machining accuracy is high.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind ofly clamp firm milling cutter, it is characterized in that: comprising: knife bar, cutterhead and blade, described knife bar upper end is provided with the described cutterhead coaxial with it, described cutterhead is provided with described blade, the front end of described blade is the milling portion protruding from described cutterhead, the postmedian of described blade is provided with the bar hole running through described blade, and the bolt be fixed on described cutterhead is fixed by described nut through after described bar hole; Described knife bar is provided with the annular groove of the described knife bar of convenient clamping.
Described cutterhead upper surface is also provided with receives bits groove.
Described receipts bits groove be semicircle, and described semicircular straight line is near the center of described cutterhead and setting perpendicular with described blade, and described semicircular arc-shaped side bends to described milling portion.
Described knife bar is cylinder or cone.
Described bolt is fixed on the center of described cutterhead and is positioned at described outside of receiving bits groove, and the length of described bolt is greater than the thickness of described blade.
The width of described bar hole is greater than the diameter of described bolt.
The overall diameter of described nut is greater than the width of described bar hole.
Described nut is double nut.
Adopt bearing to connect between described knife bar and cutterhead, described cutterhead rotates on described knife bar.
The shape of described blade is square.
Provided by the inventionly a kind ofly clamp firm milling cutter, the setting of bar hole, can when milling portion shortens, blade is moved forward, realize the sustainable utilization of blade, until the end of bar hole is just unadjustable through the length of blade after described bolt, avoid the frequent replacing of blade, greatly save cost and shortened man-hour, having improve production efficiency; The setting of double nut, achieves being fastenedly connected of blade and cutterhead, the problem such as to rock avoiding that blade causes in high-speed rotation; Receive bits groove and receive the bits shape of groove, the setting of position, while achieving the adjustable function of blade lengths, achieve the function being collected in the chip produced in milling process; The setting of annular groove, is convenient to the clamping of chucking device, makes the clamping of the present invention's whole device firm, not easily trembles, substantially increase the machining accuracy of processing parts.Provided by the inventionly a kind ofly clamp firm milling cutter, structure is simple, reasonable in design, and clamping is firm, and have and receive bits function, blade lengths is adjustable, in the service life of prolongation blade, reduces production cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described.
As shown in Figure 1 and 2, a kind ofly clamp firm milling cutter, it is characterized in that: comprising: knife bar 1, cutterhead 2 and blade 3, described knife bar 1 upper end is provided with the described cutterhead 2 coaxial with it, described cutterhead 2 is provided with described blade 3, the front end of described blade 3 is the milling portion 4 protruding from described cutterhead 2, and the postmedian of described blade 3 is provided with the bar hole 5 running through described blade 3, and the bolt 6 be fixed on described cutterhead 2 is fixed by described nut 7 through after described bar hole 5; Described knife bar 1 is provided with the annular groove 9 of the described knife bar 1 of convenient clamping.
Described cutterhead 2 upper surface is also provided with receives bits groove 8.
Described receipts bits groove 8 be semicircle, described semicircular straight line near the center of described cutterhead 2 and with the perpendicular setting of described blade 3, described semicircular arc-shaped side is bending to described milling portion 4.
