Abstract
The invention discloses a self-cooling type drill bit. A cavity is formed in the drill bit. The drill bit comprises a drill bit body at the top, a drill rod in the middle and a connecting portion with the tail pivoted to a drill bit seat. The drill bit body is in an inverted conical shape. The drill rod is in the shape formed by connecting at least two inverted circular truncated cones. The drill bit body and the drill rod are provided with multiple holes communicating with the cavity in the drill bit. A pivot joint segment body is connected with two pipes extending outwards, namely the grinding aid liquid pipe and the cooling gas pipe. The outer portion of the cooling gas pipe is connected with an air compressor. The outer portion of the grinding aid liquid pipe is connected with grinding aid equipment. The drill bit integrates drilling, lubricating and cooling, lubricating can be conducted while drilling, and no extra cooling and lubricating device needs to be designed for drilling equipment, so that the drill bit equipment is simplified. When the drill bit works, drilling and grinding efficiency can be improved through grinding aid, and the edges of drilled holes are smooth and not sharp and coarse.

Background technology
Traditional drill bit, it is solid brill, such as application number is 201520621081.7, denomination of invention is three-wing bit, when coordinating drilling machine or lathe to use, all need extra increasing on drilling machine or lathe to join coolant and cooling body, increase the area occupied of lathe, and outside lathe, place cooling liquid tank and walk liquid pipe, increasing the burden of operator.
Again such as, application number is 201420811478.8, and denomination of invention is cooling drill bit in a kind of hard alloy, is internally provided with cooling tube at drill bit blade and drill handle part；The hollow reservoir of cooling tube is filled with absorption heat transfer medium；The closed at both ends of cooling tube, one end is distributed in the end of drill handle part, the other end is distributed in the inside of drill bit blade；Being provided with louvre on drill bit blade axial surface, louvre is internal and past away from the extension of bit edge end surface, the outer wall end extending only to cooling tube tube wall to drill bit blade；Being provided with spiral thermal trough on drill handle part outer wall, the groove depth of spiral thermal trough extends, extends only to the outer wall end of cooling tube tube wall to drill handle part inside.
But it is inadequate that the heat-absorbing medium only arranged by inside absorbs the heat produced in drill bit friction process, and such type of cooling, a little heat of drill bit can only be cooled down, the workpiece rubbed with it is not had cooling effect, so cooling effect on the whole is not good.
Summary of the invention
It is an object of the invention to provide one and can carry out self-lubricating, self cooled heavy duty detergent drill bit when lathe is holed.
For solving above-mentioned technical problem, the technical solution used in the present invention is:
A kind of self-cooling type drill bit, including drill body with for installing the drill headstock of drill body, there is inside described drill body a cavity, drill body includes the drill bit at top, the drilling rod of middle part and afterbody and is articulated in the connecting portion of drill headstock, drill bit is turbination, drilling rod be shaped as by least two inverted round stage connect formed, described drill bit with drilling rod offers several holes connected with drill body internal cavities；Described drill headstock includes a pivot joint section for pivot joint drill body connecting portion, pivot joint section body is connected to outward extending two pipes, respectively grinding aid liquid line and cooling gas tube, cooling gas tube is outside to be connected with air compressor machine, and grinding aid liquid line is outside to be connected with grinding aid equipment.
During bit operation of the present invention, flowing out grinding aid and cooling gas in the hole that drill bit and drilling rod are offered, for reducing because of drill bit and the fricative high temperature of Work piece high-speed, and grinding aid can improve brill mill efficiency, and makes drilled bore edges round and smooth sharply not short-tempered.
Drill bit of the present invention integrates boring, lubricates and cool down, it is not necessary to the cooling of rig additional designs and lubricating arrangement so that rig is simplified.
Drill bit of the present invention is when boring, the hole that drill bit and drilling rod are offered is flowed out grinding aid and cooling gas, grinding aid and cooling gas mixing are flowed out from hole, rather than make grinding aid and the cooling individually designed pipeline of gas, flow out from hole respectively, it is so designed that and simplifies drill bit internal cavity body structure, it is possible to achieve the Miniaturization Design of drill bit.
Preferably, the pivot joint section of described drill headstock and the connecting portion of drill body are threaded connection.When needs change drill body repeatedly to adapt to assembling and to produce needs, can pass through to change drill body and replace prior art is changed the way of whole drill bit, operator is without buying a lot of drill bits to meet different assembling needs, also make operation easier, provide cost savings, improve work efficiency.
Between drill bit of the present invention and drilling rod, it is connected each through round platform form transition between the inverted round stage of drilling rod.
Pivot joint section one end of drill headstock of the present invention and connecting portion pivot joint, the other end of pivot joint section seals and arranges, and the pivot joint section of drill headstock is that cross is arranged with grinding aid liquid line and cooling gas tube entirety.
Grinding aid liquid line of the present invention and cooling gas tube are one-body molded with pivot joint section.
After the present invention adopts said structure, have the following technical effect that
Drill bit of the present invention integrates boring, lubricates and cool down, it is possible to hole in limit, limit cooling and lubricating, it is not necessary to the cooling of rig additional designs and lubricating arrangement so that drill bit apparatus is simplified.During bit operation of the present invention, the grinding aid flowed out in the hole that drill bit and drilling rod are offered and cooling gas, for reducing because of drill bit and the fricative high temperature of Work piece high-speed, and grinding aid can improve brill mill efficiency, and makes drilled bore edges round and smooth sharply not short-tempered.
