Description
Technical field
The utility model relates to a kind of cutter.
Background technology
Processing float grease seal seat inner chamber at present, is all use artificial reconditioning, some artificially not true in process be present
Qualitative factor, causes that circular arc that everyone reconditioning goes out and radius are different, and roughness is Ra3.2-6.3 after processing, by turning
Speed and the precision of the unmanageable processing of feeding, and the reconditioning frequency of whole process is more, processing efficiency is low, each reconditioning and
15min or so can all be delayed by changing cutter, and this is the weak point present in prior art.
The content of the invention
Technical problem to be solved in the utility model, aiming at the deficiency present in prior art, and provide a kind of
The technical scheme of floating tooling.The utility model solves in the prior art that error caused by artificial reconditioning is big, efficiency is low and changes
Knife, the technical problem to knife time length.
This programme is achieved by the following technical measures：A kind of cutter, including cutter hub, cutter head and blade, the knife
Piece is fixed on the stem of the cutter head, and the cutter hub is fixed on the afterbody of the cutter head, it is characterized in that：The both ends of the blade point
It is not provided with a point of a knife, the upper mounting surface of the blade is plane, and the lower mounting surface of the blade is trapezoidal faces, the trapezoidal faces
Two hypotenuses between angle be 90 °；The cutter head includes cutter head top and cutter head bottom, the afterbody on the cutter head top and
The afterbody of cutter head bottom is fixedly connected by nut, and the stem on the cutter head top is fixed with pressing plate, under the pressing plate and cutter head
Gap is provided between the stem in portion, the blade is fixed in the gap, the upper surface of the gap for plane and with institute
The upper mounting surface compression fit of blade is stated, the lower surface of the gap compresses for dovetail groove and with the lower mounting surface of the blade
Coordinate.
Further improvement of the utility model also has, and the pressing plate is shorter than the cutter head bottom, is easy to blade during installation
It is placed in the gap between cutter head top and cutter head bottom, meanwhile, the length of cutter head bottom is longer, blade is played more preferably
Supporting role, reduce blade caused phenomenon of rupture in use.
Further improvement of the utility model also has, and housing screw is provided with the pressing plate and pressing plate cooperation is fixed
Position, pressing plate and housing screw are used cooperatively, and play a part of fixed blade.
Further improvement of the utility model also has, and the upper surface of the pressing plate is provided with an inclined-plane, the housing screw
It is fixed on the inclined-plane, workpiece is to obstruction caused by the running orbit of cutter when the ramp structure avoids work, and then also keeps away
Exempt from after cutter hub contacts with workpiece in process to wear phenomenon caused by workpiece.
Further improvement of the utility model also has, and the side of the cutter head is fixed with balance base, the axle of the balance base
The axis perpendicular of line and the cutter head, sets the purpose of balance base to be the increase in the intensity of cutter head.
The beneficial effects of the utility model can be learnt according to the narration to such scheme：The blade of the present utility model
Both ends are respectively arranged with a point of a knife, and the upper mounting surface of the point of a knife piece is plane, and the lower mounting surface of the blade is trapezoidal faces,
Angle between two hypotenuses of the trapezoidal faces is 90 °, and the blade is fixed in the gap, and the upper surface of the gap is flat
Face and with the upper mounting surface compression fit of the blade, the lower surface of the gap for dovetail groove and with the blade
Mounting surface compression fit.This design method, the cutter material effectively utilized, facilitate user and change cutter, subtract simultaneously
Lacked in installation process to the knife time, reduce because reconditioning it is not in place caused by processing dimension and the bad phenomenon of roughness,
The cutter has the advantages that long, wear-resistant, the easy chip removal of service life.
As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress, its beneficial effect implemented
Fruit is also obvious.
