Description
Technical field
The utility model belongs to process tool technical field, and in particular to a kind of twolip roughing boring cutter.
Background technology
Boring cutter is one kind of aperture knife tool, usually round handle, also has larger workpiece user knife bar to be generally found from vertical
Vehicle, most common occasion be exactly in hole machined, reaming, profiling etc..But be not hole in can only processing, angle head cylindrical is also can
It is not traditionally only to use in this way with processing.There are one or it is two cutting tips, thick dedicated for being carried out to existing hole
The cutter of processing, semifinishing or finishing.Boring cutter can use on boring machine, lathe or milling machine.
Because of the difference of installation way, the side of having of portion handle, Morse taper shank and 7:The diversified forms such as 24 taper shanks.There are two double-blade boring cutters
The cutter tooth of both sides while cutting is centrally located, since the radial load generated during cutting mutually balances each other, cutting data can be increased, it is raw
It produces efficient.Double-blade boring cutter is divided into floating boring tool whether floating on boring bar by blade and fills boring cutter surely.Floating boring tool is suitable for
The finishing in hole.It is effectively equivalent to reamer, and energy boring goes out the hole of dimensional accuracy height and any surface finish, but be unable to trimming hole
Straight line sexual deviation.Number is refaced in order to improve, adjustable structure is often made in floating boring tool.
However, often there are certain defects in use for present roughing boring cutter：Present boring cutter because of front part of blade also
There is knife bar body, so can be obstructed during chip removal, particularly aperture chip removal can freely not cause stalk knife；Using hilted broadsword, so cutter hub
Radial load X it is bigger, cutter hub is rigidly poor, easily hair shake；Simultaneously because knife can be ground, verticality is bad when doing stepped hole.
Utility model content
It is mentioned above in the background art to solve the purpose of this utility model is to provide a kind of twolip roughing boring cutter
Because front part of blade also has knife bar body, so can be obstructed during chip removal, particularly aperture chip removal can freely not cause stalk knife；Using list
Knife, so the radial load X of cutter hub is bigger, cutter hub is rigidly poor, easily hair shake；Simultaneously because knife can be ground, when doing stepped hole
The problem of verticality is bad.
To achieve the above object, the utility model provides following technical solution：A kind of twolip roughing boring cutter, including boring cutter
Blade, blade and fixing groove, the side of the blade are provided with knife bar body, and the opposite side of the blade is provided with installation limiting
Portion, the centre position of the knife bar body are provided with chip space, and the upper and lower ends of the knife bar body are respectively arranged with blade mounting head,
The side of the blade mounting head far from blade is provided with boring cutter blade, and the side of the installation limiting section far from blade is provided with
Tail portion is installed, side centre position of the installation tail portion far from installation limiting section is provided with gland, the installation limiting section
Surface centre position be provided with fixing groove.
Preferably, the boring cutter blade is demountable standard insert, between the boring cutter blade and blade mounting head
It is fixedly connected by fastening screw.
Preferably, the blade mounting head uses and is uniformly and symmetrically distributed structure design.
Preferably, the surface of the boring cutter blade is evenly coated with heatproof coating.
Preferably, it is both provided between the boring cutter blade and blade mounting head and between blade mounting head and chip space
Convenient for the clearance groove of chip removal.
Preferably, the gland is designed using hemispherical dome structure.
Compared with prior art, the beneficial effects of the utility model are：
1st, the utility model by knife bar body using double cutting edge design, increase boring cutter bore hole when the processing area of cut,
The time required to substantially reducing boring cutter bore hole, while radial load X cancels out each other, and improves cutter rigidity, and processing is not easy hair and shakes, improves
Boring machine processing ground production efficiency, improves processing quality.
2nd, the utility model sets clearance groove before blade, facilitates the metal fillings generated during bore hole by setting chip space
Discharge in time avoids metal fillings accumulation from causing processing inconvenient, influences bore hole quality and reduces processing efficiency.
