Embodiment
Further to illustrate the present invention to reach the technological means and effect that predetermined goal of the invention is taken, to foundation
Its embodiment of angle rose reamer, feature and its effect proposed by the present invention, describe in detail as after.
As shown in figure 1, the invention discloses a kind of angle rose reamer, including cutter hub 1, knife bar 2 and it is arranged on knife bar 2
Blade 3, blade 3 are rotatably connected on knife bar 2 by rotary shaft 4, and blade 3 can move along perpendicular to the direction in the face of knife bar 2, i.e.,
Blade 3 and the distance between knife bar 2 are adjustable, so that when carrying out angular adjustment to blade 3, blade 3 can cross fixation
Post 5；
The fixed groove of insertion is provided with the position of centre of gravity of blade 3；
Also include fixing device, for blade 3 to be fixed on into knife bar 2, fixing device includes：
Fixed column 5, to be fixedly installed on the raised cylinder on knife bar 2, fixed column 5 and fixed groove are interference fits, right
When blade 3 is fixed, by outside the fixed groove insertion fixed column 5 at the position of centre of gravity of blade 3, pass through rotary shaft 4 and center of gravity position
The fixation at the place of putting is so as to realizing the overall fixation of blade 3.
In order to prevent vibration so that blade 3 play, fixed column 5 occur on the direction of knife bar 2 is tube-in-tube structure,
Including：
Fixed column main body 6, it is circular cylindrical cavity；
Mobile main body 7, mobile main body 7 are arranged on inside fixed column main body 6；
There is mobile main body 7 first state being received in inside fixed column main body 6 and one end to stretch out fixed column main body 6 and extension
Diameter is more than the second state of the external diameter of fixed column main body 6, as shown in figure 1, when being in first state, the fixed groove of blade 3
The outside of fixed column main body 6 can be smoothly inserted, as shown in Fig. 2 when being in the second state, blade 3 is fixed on outside fixed column main body 6
Side and because extension diameter is more than the external diameter of fixed column main body 6, and more than the diameter of the fixed groove on blade 3, therefore
Extension can block blade 3, prevent it from play occurs.
As a kind of perferred technical scheme, the first end 71 of mobile main body 7 connects with the inside bottom of fixed column main body 6
Connect, the second end 72 is provided with the symmetrical fixed block 722 of first fixed block 721 and second, and the first fixed block 721 and second is fixed
Connected between block 722 by compression spring 723, and the first fixed block 721 and the second fixed block 722 can be along the second ends 72
Any centerline direction is relative or moves towards；
Mobile main body 7 can move along the length direction of fixed column main body 6 and by the pulling force of cylinder body inside bottom.
As a kind of perferred technical scheme, by stretching bullet between the inside bottom of fixed column main body 6 and mobile main body 7
Spring 8 connects；
Or,
The inside bottom of fixed column main body 6 is connected with mobile main body 7 by magnet.
During in first state, the first fixed part and the second fixed part merge to form cylindrical, and in bottom magnet or
The inside of fixed column main body 6 is under the pulling force effect of extension spring 8, therefore fixed column 5 is the consistent cylinder of upper and lower diameter,
The fixed groove of blade 3 can be moved smoothly in fixed column 5；During in the second state, led under external force by mobile
Body 7 pulls out part to fixed column main body 6, and under the thrust of compression spring 723, the first fixed block 721 and the second fixed block 722 divide
Do not moved along the elastic force direction of compression spring 723 so that the diameter of extension is more than the diameter of fixed column main body 6, so as to card
The blade 3 being firmly enclosed in fixed column 5, in case play occurs in it.
As a kind of perferred technical scheme, handle 9 is provided with the first fixed block 721 and the second fixed block 722, just
Exerted a force in mobile main body 7.
As a kind of perferred technical scheme, the bottom of the first fixed block 721 and the second fixed block 722 is set fluted,
And the second end 72 is provided with the projection supporting with groove, the first fixed block 721 and the second fixed block 722 are in the second end 72
The track motion convexed to form, projection overlap with any center line of the second end 72.
As a kind of perferred technical scheme, fixed column 5 is provided with multiple, can be according to the blade 3 for being actually needed regulation
The number of angle initialization fixed column 5 and its position, so as to realize multi-angle regulation.
As a kind of perferred technical scheme, blade 3 is triangle, and three angles of triangle are respectively 45 °, 30 °,
105°.It the setting of unconventional equilateral triangle, can more facilitate 30 ° of this conventional angles of positioning, and can provide more
Range of choice.
The above described is only a preferred embodiment of the present invention, any formal limitation not is made to the present invention, though
So the present invention is disclosed above with preferred embodiment, but is not limited to the present invention, any to be familiar with this professional technology people
Member, without departing from the scope of the present invention, when the technology contents using the disclosure above make a little change or modification
For the equivalent embodiment of equivalent variations, as long as being the content without departing from technical solution of the present invention, the technical spirit according to the present invention
Any simple modification, equivalent change and modification made to above example, in the range of still falling within technical solution of the present invention.
