Description
Technical field:
This utility model is a kind of drill rod mechanism, it achieves power source and does not contact with bit operation part and indirectly provide power source, makes the purpose of bit operation.
Background technology:
For realizing the purpose that multiple drill bit works simultaneously, if adopting existing drill bit in market, each drill bit needs a motor, causes the waste of resource and the complexity of structure, thus devising a whole set of structure of drill bit to meet requirement.Multiple drill bits work simultaneously and are delivered on drilling rod through Chain conveyer by power source at a distance.Therefore a kind of drill rod mechanism facilitating implementation the power source multiple drill bits of driving is provided to become problem demanding prompt solution in prior art.
Utility model content:
In order to solve problem above, it is achieved a remote power source supplies the drill rod mechanism of multiple drill bits.This utility model provides a kind of drill rod mechanism, it is characterized in that described drill rod mechanism includes cam mechanism successively from root to end, it is sleeved in the boring in inner sleeve bar and drill bit, the cam of cam mechanism and the ends contact in pole-footing portion in boring, pocketed springs on bar in boring, the two ends of spring respectively with the flange of end in pole-footing portion in boring and inner sleeve ends contact, the inner surface of inner sleeve has internal spline, in boring, rod outer surface has the external splines coordinated with internal spline, drill bit is arranged on bar end in boring, during described inner sleeve is arranged in frame by bearing group and outer sleeve, inner sleeve outer surface is also set with chain transmission gear, chain transmission gear is connected with driving device by driving-chain.
Described a kind of drill rod mechanism, it is characterized in that described bearing group includes the first deep groove ball bearing, thrust ball bearing and the second deep groove ball bearing, first deep groove ball bearing and the second deep groove ball bearing are separately mounted to the two ends of inner sleeve, thrust ball bearing is arranged in the middle part of inner sleeve, the blowout patche of thrust ball bearing is connected with fixing with inner sleeve and outer sleeve respectively with seat ring, the space of inner sleeve and outer sleeve end adopts bearing (ball) cover to close, bearing (ball) cover is fixed on the end of outer sleeve with screw, also has sealing ring between bearing (ball) cover and inner sleeve end.
The drill rod mechanism that this utility model provides drives sprocket rotate and drive inner sleeve to rotate by Chain conveyer, inner sleeve and bar in boring are connected in drive boring bar further through spline and rotate, and simultaneously inside and outside spline fitted also can meet the requirement axially slid relative of inner sleeve and the interior bar of boring.Radial force and the axial force of bar in boring is born by deep groove ball bearing and thrust bearing.Outer sleeve is connected with bearing end cover screw and realizes stablizing of mechanism, seals with sealing ring, and whole mechanism be fixedly mounted in frame by outer sleeve between bearing (ball) cover and inner sleeve.By this series of design, make power source to rotate by remote boot server drill bit, and cam and spring can be adopted to coordinate and control the lifting of drill bit, it is simple to realize cooperation and the control of many drill bits array.
Accompanying drawing explanation

In figure:
1 cam mechanism, bar in 2 borings, 3 springs, 4 inner sleeves, chain transmission gear, 6 outer sleeves, 7 first deep groove ball bearings, 8 thrust ball bearings, 9 second deep groove ball bearings, 10 bearing (ball) covers, 11 screws, 13 driving-chains, 14 frames, 15 sealing rings, 16 drill bits.
Detailed description of the invention
In order to technical characteristic of the present utility model, purpose and effect are more clearly understood from, now comparison accompanying drawing illustrates detailed description of the invention of the present utility model.
The drill rod mechanism that this utility model provides includes cam mechanism 1 successively from root to end, it is sleeved in the boring in inner sleeve 4 bar 2 and drill bit 16, the cam of cam mechanism and the ends contact in pole-footing portion in boring, pocketed springs on bar in boring, the two ends of spring respectively with the flange of end in pole-footing portion in boring and inner sleeve ends contact, the inner surface of inner sleeve has internal spline, in boring, rod outer surface has the external splines coordinated with internal spline, drill bit is arranged on bar end in boring, described inner sleeve is arranged in frame in 14 by bearing group and outer sleeve 6, inner sleeve outer surface is also set with chain transmission gear 5, chain transmission gear is connected with driving device by driving-chain 13.
Embodiment
In the present embodiment, described bearing group includes the first deep groove ball bearing 7, thrust ball bearing 8 and the second deep groove ball bearing 9, first deep groove ball bearing and the second deep groove ball bearing are separately mounted to the two ends of inner sleeve, thrust ball bearing is arranged in the middle part of inner sleeve, the blowout patche of thrust ball bearing is connected with fixing with inner sleeve and outer sleeve respectively with seat ring, the space of inner sleeve and outer sleeve end adopts bearing (ball) cover 10 to close, bearing (ball) cover is fixed on the end of outer sleeve with screw, also has sealing ring 15 between bearing (ball) cover and inner sleeve end.
The structure of a kind of drill rod mechanism provided in the present embodiment is as shown in Figure 1.
The operation principle of the drill rod mechanism that this utility model provides is as follows:
1), drilling rod lifting
Cam mechanism is pressed sine curve and is rotated, when cam promotes bar terminad motion in boring to drive drill bit terminad stretch out and compress spring, when cam return, in boring, bar resets under the elastic force effect of spring, realize the elevating movement of drill bit, in this process bar and inner sleeve relative sliding under the effect of inside and outside spline in boring；
2), drill bit rotates
Power source drives chain transmission gear by driving-chain and then drives inner sleeve to rotate, and under the mating reaction of inside and outside spline, inner sleeve drives bar in boring to rotate.Thus realizing the rotation of drill bit.
Embodiment described above is only explanation technological thought of the present utility model and feature, its purpose will appreciate that content of the present utility model and implements according to this making those skilled in the art, when can not with restriction the scope of the claims of the present utility model, namely the equalization generally made according to the spirit that this utility model is disclosed changes or modifies, and must be encompassed in the scope of the claims of the present utility model.
