And the outside of bearing is provided with containment vessel, the junction of the cavity and drill bit screw rod is provided with the hollow pipe through bearing, described
The one end of cavity away from drill bit screw rod is provided with sweep-up pipe, and the side of cavity is provided with coolant inlet, and the drill bit screw rod is remote
One end from cavity is provided with drill bit, and the outer wall of drill bit is coated with plasma thermal diffusion layer, the center of the termination of the drill bit
Passway is provided with position, the termination of the drill bit is provided with auxiliary drill bit.
It is preferred that, the inside of the drill bit screw rod is provided with the cavity passage connected with hollow pipe and passway.
It is preferred that, the described one end of drill bit screw rod away from cavity is provided with bolt, and drill bit is installed nut by bottom and fixed
Installed in the top of drill bit screw rod.
It is preferred that, the outside of the passway is provided with mounting groove, and auxiliary drill bit passes through the fixation that is used cooperatively with mounting groove
Loop coil is arranged on the top of drill bit.
It is preferred that, the appearance of the drill bit is provided with clock wise spirals lines.
Compared with prior art, the beneficial effects of the utility model are：This has the drill bit of plasma thermal diffusion layer relative
In traditional drill bit drill bit it is outer be coated with one layer of plasma thermal diffusion layer and accelerate drill bit and friction of workpiece produce heat
Transmission, it is to avoid heat concentrates on drill bit termination, the damage caused to drill bit, and then improves the service life of drill bit, simultaneously
The dismountable auxiliary drill bit set can meet many-sided demand in Machinetool workpiece process, improve the feature of drill bit
And practicality, the cavity of setting can inject coolant and drill body is cooled by coolant, improve dissipating for drill bit
The thermal efficiency, while can be handled the chip in process by sweep-up pipe and passway, improves drill bit and is adding
Accuracy during work.
