Description
Technical field
The present invention relates to a kind of drill bit, specially a kind of self-cooling type rotary drilling-head device, belong to machining technique field.
Background technology
Traditional drill bit, is solid brill, such as Application No. 201520621081.7, entitled three-wing bit,
Coordinate drilling machine or lathe and match somebody with somebody coolant and cooling body in use, being required on drilling machine or lathe additionally increase, increase lathe
Area occupied, and placed outside lathe and cooling liquid tank and walk liquid pipe, increase the burden of operating personnel.
For another example Application No. 201420811478.8, the interior cooling drill bit of entitled a kind of hard alloy, in drill bit
Blade and drill handle part are internally provided with cooling tube；Absorption heat transfer medium is filled with the hollow reservoir of cooling tube；Cooling
Pipe it is closed at both ends, one end is distributed in the end of drill handle part, the other end is distributed in the inside of drill bit cutting portion；Drill bit cutting portion axial direction
Heat emission hole is provided with surface, heat emission hole extends to drill bit cutting portion inside and toward remote drill bit cutting portion end face, extends only to cool down
The outer wall end of tube wall；It is provided with spiral thermal trough on drill handle part outer wall, the groove depth of spiral thermal trough is to drill handle part inside
Extend, extend only to the outer wall end of cooling tube wall.
But the heat-absorbing medium only set by inside is to absorb caused heat in drill bit friction process be inadequate, and
And such type of cooling, a little heat of drill bit can only be cooled down, does not have cooling effect to the workpiece to rub therewith, so overall
On cooling effect it is bad.
The content of the invention
Self-lubricating, self cooled heavy duty detergent drill bit can be carried out when lathe drills it is an object of the invention to provide one kind.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of self-cooling type rotary drilling-head device, including drill body and the drill headstock for installing drill bit, the drill bit
Body interior has a cavity, and drill body includes the drill bit at top, the drilling rod of middle part and afterbody and is articulated in drill headstock
Connecting portion, drill bit is turbination, and being shaped as being connected by least two inverted round stage of drilling rod is formed, on the drill bit and drilling rod
Offer several holes with drill body connects with the internal cavities；The drill headstock includes one and is used to be pivotally connected drill body connection
The pivot joint section in portion, drill headstock are connected to motor different from one end of pivot joint section by rotating part, are pivotally connected between section and rotating part and set
There is a closed chamber, the closed chamber is connected with two pipes to stretch out, respectively grinding aid liquid line and cooling gas pipe,
It is connected with air compressor machine outside cooling gas pipe, is connected outside grinding aid liquid line with grinding aid equipment.
Motor driven swivel head of the present invention, swivel head drive drill bit to rotate, and drill bit rotates when drilling downwards, can improved
Drilling efficiency.During bit operation, grinding aid and cooling gas are flowed out in the hole that drill bit and drilling rod open up, for reduce because drill bit with
High temperature caused by Work piece high-speed friction, and grinding aid can improve brill mill efficiency, and make drilled bore edges round and smooth not sharp
It is sharp short-tempered.
Drill bit of the present invention integrates drilling, lubricates and cool down, it is not necessary to which rig additional designs cool down and lubrication dress
Put so that rig is simplified.
Drill bit of the present invention flows out grinding aid and cooling gas in the hole that drill bit and drilling rod open up in drilling, grinding aid and
Cooling gas mixing is flowed out from hole, rather than makes grinding aid and the individually designed pipeline of cooling gas, is flowed out respectively from hole, such as
This design simplifies drill bit internal cavity body structure, it is possible to achieve the Miniaturization Design of drill bit.
Connected between drill bit and drilling rod of the present invention, between the inverted round stage of drilling rod by the transition of round platform form.
Pivot joint section, rotating part, grinding aid liquid line and the cooling gas pipe of drill headstock of the present invention are in integrally cross
It is arranged at the outside of closed chamber.
Grinding aid liquid line and cooling gas pipe of the present invention are integrally formed with drill headstock.
The pivot joint section of drill headstock of the present invention and the connecting portion of drill body are connected through a screw thread.When needing to change repeatedly
When drill body is to adapt to assemble and produce needs, it can replace changing whole drill bit in the prior art by changing drill body
Way, operator meets different assembling needs without many drill bits of purchase, also make it that operation is easier, save
Cost, improve operating efficiency.
After the present invention uses said structure, have the following technical effect that：
Motor driven swivel head of the present invention, swivel head drive drill bit to rotate, and drill bit rotates when drilling downwards, can improved
Drilling efficiency.Drill bit integrates drilling, lubricates and cool down, and can be drilled with side, side cooling and lubricating, it is not necessary to which rig is extra
Design cooling and lubricating arrangement so that drill bit apparatus is simplified.During bit operation, what is flowed out in the hole that drill bit and drilling rod open up helps
Grinding agent and cooling gas, for reducing because of high temperature caused by drill bit and Work piece high-speed friction, and grinding aid can improve brill mill
Efficiency, and make drilled bore edges round and smooth not sharp short-tempered.
