Abstract

The invention discloses a length-adjustable milling cutter which is characterize by comprising a cutter bar (1), a cutter head (2) and a cutter blade (3), wherein the cutter head (2) which is coaxial with the cutter bar (1) is arranged at the upper end of the cutter bar (1); the cutter blade (3) is arranged on the cutter head (2); a milling part (4) which protrudes from the cutter head (2) is arranged at the front end of the cutter blade (3); a strip-shaped hole (5) which penetrates through the cutter blade (3) is formed in the middle rear part of the cutter blade (3); a bolt (6) which is fixed on the cutter head (2) passes through the strip-shaped hole (5) to be fixed by a nut (7). According to the length-adjustable milling cutter provided by the invention, the structure is simple, the design is reasonable, the length of the cutter blade is adjustable, the service life of the cutter blade is prolonged, and the production cost is reduced.

Description

A kind of length adjustable milling cutter
Technical field
The present invention relates to a kind of length adjustable 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.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of blade lengths adjustable milling cutter; Further, the length adjustable milling cutter providing a kind of blade fixed.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of length adjustable 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 bolt is fixed on the center of described cutterhead, 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 length adjustable milling cutter provided by the invention, 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.A kind of length adjustable milling cutter provided by the invention, structure is simple, and reasonable in design, blade lengths is adjustable, extends the service life of 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 of length adjustable 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 bolt 6 is fixed on the center of described cutterhead 2, and the length of described bolt 6 is greater than the thickness of described blade 3.
The width of described bar hole 5 is greater than the diameter of described bolt 6.
The overall diameter of described nut 7 is greater than the width of described bar hole 5.
Described nut 7 is double nut.
Adopt bearing to connect between described knife bar 1 and cutterhead 2, described cutterhead 2 rotates on described knife bar 1.
The shape of described blade 3 is square.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
