Abstract
The utility model relates to a kind of composite numeric control handle of a knife, comprises handle of a knife matrix, and the outer surface of described handle of a knife matrix is cast with composite bed, and this handle of a knife matrix is shaping by steel pipe time processing; The annexation of described composite bed and handle of a knife matrix is: the outer surface of handle of a knife matrix is provided with several dovetail groove, is filled with composite bed in described dovetail groove.The utility model has the advantages that: due to the existence of composite bed, under the prerequisite not increasing processing cost, the toughness of handle of a knife can not change, and extends service life, alleviates the overall weight of handle of a knife, and easily processes, and conveniently carries out dynamic balancing.
Description
Technical field
The utility model relates to a kind of composite numeric control handle of a knife, belongs to the machine tool field of machining.
Background technology
Numerical control handle of a knife is one of instrument important in machining, for clamping cutter, carries out machining to workpiece, and its drawback existed is: heavier-weight, because needs are by mechanical arm clamps, causes the wearing and tearing of draw-in groove boss, shorten the service life of handle of a knife.
Summary of the invention
For overcoming the defect of prior art, the utility model provides a kind of composite numeric control handle of a knife, the technical solution of the utility model is: a kind of composite numeric control handle of a knife, comprise handle of a knife matrix, it is characterized in that, the outer surface of described handle of a knife matrix is cast with composite bed, and this handle of a knife matrix is shaping by steel pipe time processing; The annexation of described composite bed and handle of a knife matrix is: the outer surface of handle of a knife matrix is provided with several dovetail groove, is filled with composite bed in described dovetail groove.
Described handle of a knife matrix comprises the taper shank, draw-in groove boss, knife bar and the locking nut that set gradually, the inside of the necking end of described taper shank forms internal thread, the knife bar at this taper shank flared end place is provided with draw-in groove boss, draw-in groove boss middle part formed annular manipulator draw-in groove, the other end of described knife bar is provided with external screw thread, locking nut coordinates with external screw thread, and the outside of this locking nut forms chamfering; The annexation of described knife bar and draw-in groove boss is: the outer wall of knife bar is provided with several dovetail groove, and the inwall of described draw-in groove boss is provided with and the dovetail groove of knife bar outer wall dovetail tangs one to one.
The utility model has the advantages that: due to the existence of composite bed, under the prerequisite not increasing processing cost, the toughness of handle of a knife can not change, and extends service life, alleviates the overall weight of handle of a knife, and easily processes, and conveniently carries out dynamic balancing.
