The cylindrical section of connection and the round platform section being connect with cylindrical section；The first screw hole of drillstock is provided through on the drillstock, on drill neck
It is provided through the second screw hole of drill neck, third screw hole is provided on drill bit；Be provided on the drill bit and be screwed into first, second,
Fastening bolt in third screw hole.
The fastening bolt center is provided with the first cooling fluid apertures, and connection the first cooling fluid apertures is provided on the drill neck
Coolant liquid is portalled.By opening up the first cooling fluid apertures in fastening bolt center, bored in order to which coolant liquid is flowed by fastening bolt
In head, and portalled by the first coolant liquid and flow out drill neck, and flows into drill bit outer surface.
The drill neck coolant liquid place of portalling is provided with baffle, and the channel that connection coolant liquid is portalled is provided in the baffle；Institute
The side for stating baffle towards drill bit is evenly equipped with the through-hole of several communicating passages.By the way that baffle is arranged, splashing on the one hand can be blocked
Metal fillings, on the other hand through-hole is set on baffle, in order to which coolant liquid is uniformly injected on cutter head as possible.
The fastening bolt is located at the end sleeve in third screw hole and is equipped with sealing ring, and connection third screw hole is provided in drill bit
Second cooling fluid apertures, this second cooling fluid apertures run through drill bit.By the way that sealing ring is arranged, avoid flowing into the cooling in third screw hole
Liquid reflux enters in the second screw hole；Coolant liquid in third screw hole flows into drill bit bottom by the second cooling fluid apertures.
The beneficial effects of the invention are as follows：Due to being provided with boss on drill neck, being provided with mounting groove on drill bit, assembling
When, boss can be inserted into mounting groove, on the one hand play the role of guiding and support in this way, on the other hand can ensure drill neck
With the concentricity of drill bit；Due to being provided with round platform section on boss so that the effect of guide effect and guarantee concentricity is more preferable；Pass through
Fastening bolt is screwed into the first, second, third screw hole, drill bit can be connected on drill neck, in order to subsequently be welded
When, it is possible to prevente effectively from there is the problem of falling off, rotating, shake in drill bit；Since drill bit uses wolfram steel material, to increase drill bit
Hardness and strength；And other materials may be used in drill neck and drillstock, can effectively reduce production cost.
Description of the drawings
Through the following detailed description taken in conjunction with the accompanying drawings, present invention objects, features and advantages above-mentioned and other will become
Obviously.
Wherein：Fig. 1 is schematic structural view of the invention；
Fig. 2 is clamping support schematic diagram of the present invention；
In attached drawing, 1 is drillstock, and 2 be drill neck, and 3 be drill bit, and 4 be cutting edge, and 5 be helicla flute, and 6 be boss, and 7 be mounting groove,
8 be cylindrical section, and 9 be round platform section, and 10 be the first screw hole, and 11 be the second screw hole, and 12 be third screw hole, and 13 be fastening bolt, and 14 are
First cooling fluid apertures, 15 portal for coolant liquid, and 16 be baffle, and 17 be channel, and 18 be through-hole, and 19 be sealing ring, and 20 is cold for second
But fluid apertures, 21 be rubber sleeve.
Specific implementation mode
Shown in Fig. 1-Fig. 2, ultraphotic deep-hole alloy bore, which is characterized in that including drillstock 1, drillstock connect drill neck 2,
