Description
Technical field
The utility model relates to a kind of milling cutter, belongs 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.
Utility model content
Technical problem to be solved in the utility model is, provides a kind of blade lengths adjustable milling cutter; Further, the milling cutter providing a kind of blade fixed; Further, a kind of milling cutter with collection of debris function is provided.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of 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 cutterhead is also provided with and 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 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.
A kind of milling cutter that the utility model provides, 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.A kind of milling cutter that the utility model provides, structure is simple, reasonable in design, and have and receive bits function, blade lengths is adjustable, extends the service life of blade, reduces production cost.
Accompanying drawing explanation
