Abstract
The utility model discloses a kind of high antitorque grinding machine head, including ontology (1), ontology (1) is concentric reducer cylindrical structure；Ontology (1) major diameter end face is equipped with one group of keyway (6), and keyway (6) and one group of high-strength anti-torsion key (2) at hard alloy layer (3) back side are connected as one.The utility model mills one group of dowel hole, hard alloy built-up welding since in dowel hole in the big bottom cylindrical face of ontology, and is covered with entire big bottom cylindrical face and is forming hard alloy layer formation high-strength anti-torsion key.The junk that grinds being ground is discharged from hydrophthalmia through flowing through the water-carrying groove of big cylindrical body bottom surface and hard alloy layer.The utility model is designed reasonably, result are simple, are easily worked.Torsional strength can be greatly enhanced, so that grinding tool service life is extended 2~3 times, overcomes the defect of the prior art.
Description
Technical field
The utility model relates to a kind of high antitorque grinding machine heads, belong to oil drilling tool technical field.
Background technique
When junk can not pick up in oil well, it will usually grind junk using grinding tool in well, recycle drilling fluid
Circulation mince by what grinding generated and rush to ground.Then can just continue to creep into.
The hard alloy layer of prior art grinding tool is directly to weld with grinding tool ontology end face.This connection side
Formula has certain unstability, when be ground fish, when torque is excessive, can make hard alloy layer integrally from grinding tool ontology
End face falls off, to make grinding tool that can not continue to be ground and scrap.Due to falling off, hard alloy layer hardness is very high, is not easy to grind
It cuts, shaft bottom situation can be made more to complicate, cause unnecessary fishing, improve drilling cost.
Utility model content
The purpose of the utility model is to provide a kind of high antitorque grinding machine heads, to prevent grinding tool when being ground
Hard alloy layer integrally is fallen from grinding tool body end emaciated face, cause unnecessary fishing, thus reduce drilling cost and
Overcome the deficiencies in the prior art.
To achieve the above objectives, the present invention adopts the following technical solutions:
A kind of high antitorque grinding machine head of the utility model, including ontology, ontology are concentric reducer cylindrical structure；Ontology major diameter
End face is equipped with one group of keyway, and keyway and one group of high-strength anti-torsion key connection at the hard alloy layer back side are integrated.
In the aforementioned antitorque grinding machine head of height, the shape of the keyway is rectangle, circle or diamond shape.
In the aforementioned antitorque grinding machine head of height, the keyway is along the circumferential direction radial uniformly distributed.
In the aforementioned antitorque grinding machine head of height, hydrophthalmia is equipped in the ontology；Hydrophthalmia is communicated through one group of water-carrying groove with body exterior.
In the aforementioned antitorque grinding machine head of height, one group of water-carrying groove is located at ontology major diameter end face and connect with hard alloy layer
Place, and circumferentially radial distribution.
In the aforementioned antitorque grinding machine head of height, one group of keyway of ontology major diameter end face is between water-carrying groove.
In the aforementioned antitorque grinding machine head of height, the hard alloy layer is equipped with water-carrying groove corresponding with ontology end face location and shape
With high-strength anti-torsion key.
By adopting the above-described technical solution, the utility model mills one group of dowel hole in the big bottom cylindrical face of ontology, hard is closed
Gold built-up welding since in dowel hole, and be covered with entire big bottom cylindrical face and forming hard alloy layer formation high-strength anti-torsion key.Mill
The junk that grinds chipped away is discharged from hydrophthalmia through flowing through the water-carrying groove of big cylindrical body bottom surface and hard alloy layer.The utility model
Have the advantages that design is reasonable, structure is simple, be easily worked, be low in cost, the utility model can greatly enhance torsional strength, make
Grinding tool service life extends 2~3 times, overcomes the defect of the prior art.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the big cylinder schematic bottom view of ontology；
Fig. 3 is that hard alloy layer and big cylinder joint face are illustrated.
In the figure, it is marked as 1- ontology, 2- high-strength anti-torsion key, 3- hard alloy layer, 4- water-carrying groove, 5- hydrophthalmia, 6- keyway,
7- circulating opening.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
A kind of high antitorque grinding machine head of the utility model, as shown in Figures 1 to 3, including ontology 1, ontology 1 are concentric reducer cylinder
Structure；It is characterized by: 1 major diameter end face of ontology is equipped with one group of keyway 6, one group of keyway 6 and 3 back side of hard alloy layer is high-strength
Antitorque key 2 is spent to be connected as one.The shape of keyway 6 is rectangle, circle or diamond shape.Keyway 6 is along the circumferential direction radial uniformly distributed.This
Hydrophthalmia 5 is equipped in body 1；Hydrophthalmia 5 outside one group of water-carrying groove 4 and ontology 1 through communicating.One group of water-carrying groove 4 is located at 1 larger diameter end of ontology
Face and 3 junction of hard alloy layer, and circumferentially radial distribution.One group of keyway 6 of 1 major diameter end face of ontology is located at water-carrying groove
Between 4.Hard alloy layer 3 is equipped with water-carrying groove 4 corresponding with 1 endface position of ontology and shape and high-strength anti-torsion key 2.
Embodiment
This example is mainly made of ontology 1, high-strength anti-torsion key 2, hard alloy layer 3, water-carrying groove 4, hydrophthalmia 5.The master of this example
Wanting feature is that ontology 1 and the coupling part of hard alloy layer 3 have added several high-strength anti-torsion keys 2.When it is implemented, in ontology 1
Big bottom cylindrical face mills several keyways 6, and the pile-up welding hard alloy since in keyway 6 forms high-strength anti-torsion key 2 and hard alloy layer
3.The big cylindrical sides in bottom have water-carrying groove 4, and the junk ground is poured water-carrying groove 4 by circulating opening 7 and followed by water-carrying groove 4
Ring well liquid is discharged from hydrophthalmia 5.
