Description
Technical field
This disclosure relates to mine drilling machine technical field more particularly to a kind of drilling machine with bias correcting structure.
Background technology
During mine construction, need to drill on rock or concrete.Drilling device, must when bore operation starts
It need be acted on drill bit with positive pressure, the increment face of end tooth is made to be contacted with concrete, to ensure the straight ahead of drilling.By
During the uncertainty of geology soil layer, bit bore, if the positive pressure that drill bit is subject to has offset, it just will appear duct
It is crooked so that the hole drilled out is in non-circular, and the accuracy in duct substantially reduces.
Currently, drilling device is divided into two kinds, one is manual operationss, can only rule of thumb control drill bit advancing direction, right
Worker's proficiency requires high, high labor cost, and efficiency is low；Equipment deviates automatic detection function with drill bit in second, still,
But when detecting drill bit offset, artificial correction after can only shutting down.
Invention content
Technical problems based on background technology, the present disclosure proposes a kind of drilling machines with bias correcting structure.
A kind of drilling machine with bias correcting structure that the disclosure proposes, including：Fixed ring, fixed ring are mounted on drilling machine
On supporting rack, and it is set in the drills outer circumference of drilling machine；Fixed ring is equipped with multiple threaded holes being uniformly distributed circumferentially, each screw thread
Kong Jun is matched with a screw rod, and each screw rod is inserted into corresponding threaded hole, and each screw rod is located at one end of fixed ring inner circumferential and is equipped with
One abutment plate, abutment plate are rotatablely connected with corresponding screw rod.
Preferably, abutment plate with drill bit against being bonded in the state of drill bit.
Preferably, spring is arranged on screw rod, spring is between fixed ring and abutment plate.
Preferably, abutment plate is equipped with cushion on one side close to drill bit.
Preferably, cushion uses rubber pad.
Preferably, each abutment plate is correspondingly provided with a guide rod, and guide rod one end is fixedly connected with fixed ring, the other end
It is inserted into abutment plate.
It, can be by abutment plate circumferential direction by adjusting screw rod in a kind of drilling machine with bias correcting structure that the disclosure proposes
It is resisted against drills outer circumference, then, each abutment plate can be adjusted by screw rod to drill bit against power, to adjust the deflection of drill bit
Direction.In this way, when each abutment plate is identical to the resistance of drill bit so that uniform force is distributed in the circumferential direction of drill bit, can be ensured
Drill bit straight line punches；Conversely, when drill bit punching offset, by tightening screw rod, the abutment plate on drill bit offset direction is increased to spiral shell
The extruding force of bar, can another drill bit inverse offset, to be modified to drill bit punching path.
Description of the drawings
Fig. 1 is a kind of drilling machine local structural graph with bias correcting structure that the disclosure proposes.
Specific implementation mode
Referring to Fig.1, a kind of drilling machine with bias correcting structure that the disclosure proposes, including：Fixed ring 1.
Fixed ring 1 is mounted on the supporting rack of drilling machine, and is set in 2 periphery of drill bit of drilling machine.Fixed ring 1 is equipped with multiple
The threaded hole being uniformly distributed circumferentially, each threaded hole are matched with a screw rod 3, and each screw rod 3 is inserted into corresponding threaded hole, and each
One end that screw rod 3 is located at 1 inner circumferential of fixed ring is all provided with there are one abutment plate 4, abutment plate 4 and the rotation connection of corresponding screw rod 3, to keep away
Exempting from abutment plate 4 follows screw rod 3 to rotate.
In present embodiment, by adjusting screw rod 3, abutment plate 4 circumferentially can be resisted against 2 periphery of drill bit, then, Bian Ketong
It crosses screw rod 3 and adjusts each abutment plate 4 to drill bit 2 against power, to adjust the deflection direction of drill bit 2.Specifically, working as each abutment plate
The resistance of 4 pairs of drill bits 2 is identical so that uniform force is distributed in the circumferential direction of drill bit 2, can ensure that drill bit straight line punches；Conversely,
It is deviated when drill bit 2 punches, by tightening screw rod 3, increases extruding force of the abutment plate 4 on 2 offset direction of drill bit to screw rod 3, just
Can another 2 inverse offset of drill bit, be modified to punch path to drill bit 2.
In present embodiment, each abutment plate 4 is and the matched cambered surface in 2 side of drill bit close to the one side of drill bit 2 so that, it supports
Backup plate 4 with drill bit 2 against being bonded in the state of drill bit 2.In this way, in 3 rotation process of screw rod, can by drill bit 2 to abutment plate 4 into
Row screens avoids abutment plate 4 that screw rod 3 is followed to rotate.Meanwhile abutment plate 4 is contacted with 2 face of drill bit, it is ensured that abutment plate 4 is to drill bit
2 pressure stepless action is on drill bit.
Specifically, in present embodiment, each abutment plate 4 is correspondingly provided with a guide rod 5,5 one end of guide rod and fixation
Ring 1 is fixedly connected, and the other end is inserted into abutment plate 4, and abutment plate 4 is slidably connected with guide rod 5, to further by guide rod 5
Avoid abutment plate 4 that screw rod 3 is followed to rotate.
In present embodiment, spring is arranged on screw rod 3, spring is between fixed ring 1 and abutment plate 4, will pass through
Spring buffer drill bit 2 avoids drill bit 2 from deviating the pressure of each abutment plate 4 by the opposition of spring.Abutment plate 4 is close
Drill bit 2 is equipped with cushion on one side, avoids that frictionally damage occurs with abutment plate 4 in 2 rotation process of drill bit.Cushion uses rubber
Rubber cushion.
The above, only this disclosure relates to preferable specific implementation mode, but the protection domain of the disclosure not office
It is limited to this, any one skilled in the art is in the technical scope that the disclosure discloses, according to the technology of the disclosure
Scheme and its open design are subject to equivalent substitution or change, should all cover within the protection domain of the disclosure.
