Description
Technical field
The utility model is related to roller cutter bit field, more particularly to a kind of convenient disassembly vibration damping inserted tooth hob drill bit.
Background technology
Anti- well rig technological principle is the motor belt motor hydrodynamic pressure motor by rig, fluid motor-driven tap, and profit
Drilling system is delivered torque to hydraulic power, the hobboing cutter on drilling rod and bit, guide hole drill bit or reaming bit is driven
In the presence of the pressure of the drill, pure rolling or micro sliding are done along bottom rock working face.The axial direction that main frame oil cylinder is produced simultaneously is drawn, pressure
Power, is acted on guide hole drill bit or reaming bit also by unit head, drilling rod, the hobboing cutter of guide hole drill bit is rolled under the pressure of the drill effect
It is dynamic, impact load is produced, hob teeth is produced impact, extruding and shear action, fractured rock to rock.
Number of patent application discloses a kind of anti-well drill bit of drilling machine for CN201520047492.X utility model patent, including
Cutterhead, drilling rod and the conical cutter head for being inlaid with steel alloy, the drilling rod vertical welding is in the center of cutterhead, the conical knife
Head is six, and the big ends of six conical cutter heads outwards, around drilling rod is radial is laid, and on the knife rest of cutterhead, is in
The conical cutter head of six of radial laying is followed successively by a cutter head, No. two cutter heads, No. three cutter heads, No. four cutter heads, No. five cutter heads
And No. six cutter heads, minimum distance of the small end away from drilling rod of a cutter head is 60mm, the central axis and cutterhead of a cutter head
Angle be 30 °；Minimum distance of the small end away from drilling rod of No. three cutter heads and No. five cutter heads is 190mm, No. three cutter heads and No. five knives
The central axis and the angle of cutterhead of head are 20 °；Most low coverage of the small end away from drilling rod of No. two cutter heads, No. four cutter heads and No. six cutter heads
From for 320mm, the angle of No. two cutter heads, the central axis of No. four cutter heads and No. six cutter heads and cutterhead is 10 °.The drill bit is by changing
The angle between the discrepancy in elevation and each cutter head and cutterhead between cutterhead, cutter head is made, makes working face formation one of the drill bit on rock
Individual flared shape, so that the damage resistance power for the rock that each cutter head is contacted reduces, reduces cutter head unbalance stress
Phenomenon, the resistance of suffered rock during reduction cutter head work, and then reduce the moment of torsion of drilling rod and cutterhead reduces drill bit impaired
Probability, extends the service life of drill bit, improves operating efficiency.
But, the above-mentioned cutter head complex operation as the cutter head of conventional bit when mounted, because cutter head is more, it is necessary to even
More bolt is connect, service working time is longer, low production efficiency.When dismantling cutter head, because cutter head is connected with drill main body
Place is covered by more landwaste, dismantle it is more difficult, and bolt may be stuck cause cutter head dismounting do not get off.During bit operation,
Cutter head may be caused cutter head to damage by larger impact.The cutter head of existing drill bit is fixed and upper without buffer gear, cutter head by
To during greater impact, the space that cutter head is not avoided so that cutter head damage probability is increased, service life reduction.
