The utility model relates to a kind of T-slot cutter, and the especially a kind of assembled T-slot cutter that can change cutting plate for milling cutters, belongs to metal cutting tool technical field.
Background technology
On the work top of all kinds of lathes, be equipped with and be convenient to fixing work piece or the T-shaped groove with moulds of industrial equipment, the standard type of conventional Integral T slotting cutter adopts the knife bar of 45# steel and the T-shaped groove cutter head butt welding of high-speed tool steel to form, as T-shaped groove cutter head damages or the wearing and tearing efficiency T-slot cutter of pruning is scrapped, waste greatlyr, use cost is higher.
In order to address the above problem, extend the service life of T-slot cutter, now there is the removable T-slot cutter of blade, as the Chinese utility model patent of CN 203197354 discloses a kind of " T-slot cutter of changeable blade ", the cutter head of this T-slot cutter and knife bar are still overall structure, the cutting end of cutter hub is provided with the blade installing rack that is cross distribution, on described blade installing rack, have the mounting groove for fixturing blade, in blade installation slot, be tiltedly installed with respectively upper blade and lower blade.The cutter hub of this T-slot cutter can Reusability, and more allowing blade replacement is convenient, thereby reaches the object that reduces the cost of charp tool.This utility model patent adopts the screw of blade and cutter head to be connected and substitutes cutter head and the soldered structure of carbide chip, the welding difficulty that has solved carbide chip and first two unlike material of cutter is large, process difficult problem, but this structure cannot be applied to the T-slot cutter that profile is less.
Utility model content
The purpose of this utility model is to provide a kind of simple in structure, cutter head and knife bar and adopts the T-slot cutter of mechanical connection.
The utility model is achieved by the following technical programs:
A kind of combination type T T-slot cutter, comprise T-shaped groove cutter head and knife bar, described T-shaped groove cutter head rear side extends axially out the cutter head nose bar matching with knife bar external diameter, described cutter head nose bar comprises and the cylindrical section of T-shaped groove cutter head junction and the frustum section being connected with cylindrical section, knife bar front end is axially arranged with the taper counterbore matching with frustum section, and T-shaped groove cutter head is fixedly connected with integral with knife bar front end by housing screw; The junction of T-shaped groove cutter head and knife bar is also provided with the chimeric rotation-preventing mechanism of Tenon, the tongue-and-groove that the chimeric rotation-preventing mechanism of described Tenon comprises a pair of tenon and matches with tenon.
The utility model can also further be realized by following technical measures.
Aforesaid combination type T T-slot cutter, wherein said a pair of tenon is symmetricly set on knife bar front end both sides, a pair of tongue-and-groove is symmetricly set on the frustum section front end both sides of cutter head nose bar, or a pair of tenon is symmetricly set on the frustum section front end both sides of cutter head nose bar, a pair of tongue-and-groove is symmetricly set on knife bar front end both sides.
Aforesaid combination type T T-slot cutter, the cone angle of wherein said frustum section and the taper counterbore that matches is with it 58 °～62 °.
The utility model is simple in structure, easily manufactured, and knife bar can be reused, and has effectively saved material.The chimeric rotation-preventing mechanism of Tenon of the junction of T-shaped groove cutter head and knife bar, can prevent that T-shaped groove cutter head and knife bar from relatively rotating effectively.Cutter head nose bar frustum section coordinates closely with taper counterbore registration, taper surface under the effect of housing screw, guarantees efficiently, the T-shaped groove of machining reliably.
Advantage and disadvantage of the present utility model, by for illustration and explanation the non-limitative illustration by preferred embodiment below, these embodiment, only provide as an example with reference to accompanying drawing.
