Abstract
The utility model relates to a well drilling tool, in particular to a drilling and reaming device for well drilling. According to the technical scheme, the drilling and reaming device comprises a shell, a milling cutter, a lug, a sliding block, a support and a shaft rod. The middle of the shell is a center through groove, a radial hole is formed in the lateral side of the shell, the shaft rod is fixed in the radial hole, a spring is arranged in the shaft rod, the shell is provided with the support, the milling cutter is fixed to the support, the sliding block is arranged at the bottom of the support, and the lug is installed in the support. The drilling and reaming device has the advantages that reaming is further carried out in real time, circulation time is short, drilling efficiency is improved, and working ability and reliability of a reamer are improved; because the spring is located in the shaft rod and plays a role in preventing pressure from being too large and damaging the milling cutter when rock stratum conversion is carried out, the service life of the milling cutter can be prolonged.
Description
Technical field
The utility model relates to a kind of drilling tool, and particularly Counterboring apparatus is crept in a kind of drilling well.
Background technology
Development along with drilling technology, market competition is growing more intense and reduces drilling time in well drilling industry and improve the focus that bit speed becomes current well drilling industry, traditional drilling mode no longer adapts to the development of this socialization, propelling drilling technology is imperative, the method a lot of one that improves bit speed is structure, manufacturability and the material of improvement drill bit, and another kind is exactly the pressure of liquid stream while increasing drilling well.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides a kind of drilling well to creep into Counterboring apparatus, improves drilling efficiency, has improved ability to work and the reliability of reamer.
Its technical scheme is: comprise housing, milling cutter, lug, slide block, bearing, axostylus axostyle, groove centered by the centre of housing, the side of housing is provided with radial hole, fixed axostyle in radial hole, in axostylus axostyle, be provided with spring, housing is provided with bearing, fixing milling cutter on described bearing, the bottom of bearing is provided with slide block, and lug is arranged in bearing.
The outside of above-mentioned housing is provided with helical tooth.
The beneficial effects of the utility model are: expand in real time reaming, circulation timei is short, improve drilling efficiency, the ability to work and the reliability that have improved reamer, spring is arranged in axostylus axostyle, and its effect is while running into rock stratum conversion, avoid that pressurized is excessive and damage milling cutter can increase application life of milling cutter like this.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is right views of the present utility model;
Accompanying drawing 3 is left views of the present utility model;
In upper figure: housing 1, helical tooth 2, milling cutter 3, lug 4, slide block 5, bearing 6, axostylus axostyle 7.
The specific embodiment
By reference to the accompanying drawings, the utility model will be further described:
The utility model comprises housing 1, milling cutter 3, lug 4, slide block 5, bearing 6, axostylus axostyle 7, groove centered by the centre of housing 1, the side of housing 1 is provided with radial hole, fixed axostyle 7 in radial hole, in axostylus axostyle 7, be provided with spring, housing 1 is provided with bearing 6, fixing milling cutter 3 on described bearing 6, the bottom of bearing 6 is provided with slide block 5, and lug 4 is arranged in bearing 6.
Wherein, the outside of housing 1 is provided with helical tooth 2, adopts the alloy material of high rigidity to make.
Bearing is for supporting with fixing reaming milling cutter at main shaft; Slide block is positioned at the bottom of bearing, and effect is to be convenient to exit while running into swaging clamp in reaming process; Its another effect is to make reaming area increase; Slide block can move up and down among a small circle; Spring is arranged in axostylus axostyle, its effect is while running into rock stratum conversion, avoid pressurized excessive and damage milling cutter, can increase the application life of milling cutter like this, the effect of lug is when slide block moves reaming, make to keep between milling cutter certain milling distance always, thereby ensure between milling cutter and do not bump, avoid milling cutter damage.Milling cutter adopts pyramid structure, all inlays according to a certain percentage for every layer, and higher raising reaming speed, has also avoided the unequal problem of milling simultaneously in the course of the work.
