It is provided through the second screw of drill neck, drill bit is provided with the 3rd screw；Be provided with described drill bit and be screwed into first, second,
Fastening bolt in 3rd screw.
Described fastening bolt central authorities are provided with the first cooling fluid apertures, and described drill neck is provided with connection the first cooling fluid apertures
Coolant is portalled.By opening up the first cooling fluid apertures in fastening bolt central authorities, flowed into by fastening bolt in order to coolant and bore
In head, and portalled outflow drill neck by the first coolant, and flow into drill bit outer surface.
The described drill neck coolant place of portalling is provided with baffle plate, is provided with the passage that connection coolant is portalled in this baffle plate；Institute
State baffle plate and be evenly equipped with the through hole of some communicating passage towards the side of drill bit.By arranging baffle plate, splashing on the one hand can be blocked
Metal fillings, on the other hand on baffle plate arrange through hole, be uniformly injected on cutter head in order to coolant as far as possible.
The end that described fastening bolt is located in the 3rd screw is arranged with sealing ring, is provided with connection the 3rd screw in drill bit
Second cooling fluid apertures, this second cooling fluid apertures run through drill bit.By arranging sealing ring, it is to avoid flow into the cooling in the 3rd screw
Liquid reflux enters in the second screw；Coolant in 3rd screw, by the second cooling fluid apertures, flows into drill bit bottom.
The beneficial effects of the utility model are: due to being provided with boss on drill neck, being provided with mounting groove on drill bit, therefore exist
During assembling, boss can be inserted in mounting groove, so on the one hand play guiding and the effect supporting, on the other hand can ensure that
Drill neck and the axiality of drill bit；Due to round platform section being provided with boss so that the effect of guide effect and guarantee axiality is more preferable；
By being screwed into fastening bolt in first, second, third screw, drill bit can be connected on drill neck, in order to subsequently carry out
During welding, the problem that coming off, rotating, shake occur in drill bit can be prevented effectively from；Because drill bit adopts wolfram steel material, to increase brill
The hardness of head and intensity；And drill neck and drillstock can adopt other materials, can effectively reduce production cost.
Brief description
By detailed description below in conjunction with the accompanying drawings, the aforesaid and other objects, features and advantages of this utility model will
Become apparent.
