Compared with drilling rod fixture in the prior art, it is formed on the fixture block seat and fixture block of fixture of the invention by guide groove
The position-limit mechanism constituted with fin, which can prevent fixture block from radially squeezing baffle, to extend fixture
Service life.
Detailed description of the invention
In order to illustrate the technical solution of the embodiments of the present invention more clearly, needing to make described in below embodiment being described
Attached drawing is briefly described, it should be apparent that, the accompanying drawings in the following description is only some embodiments of the present invention, for this
For the those of ordinary skill of field, without creative efforts, it can also be obtained according to these attached drawings others
Attached drawing.Wherein:
Fig. 1 is the top view of drilling rod fixture provided by the invention in a specific embodiment；
Fig. 2 is the left view of the drilling rod fixture in Fig. 1 embodiment；
Fig. 3 is the partial resolution figure of the drilling rod fixture in Fig. 1 embodiment.
Specific embodiment
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, with reference to the accompanying drawing and specific real
Applying mode, the present invention is described in further detail.
Please refer to shown in Fig. 1 to Fig. 3, drilling rod fixture provided by the invention include fixture block seat 1, right baffle-plate 2, right shell body 3, on
The components such as fixture block 4 and lower fixture block 5.Wherein:
It is formed with the curved guiding surface 11 being recessed inwardly in the fixture block seat 1, has been axially formed on the curved guiding surface 11
Upper guide groove 12 and lower guide groove (not shown).The upper guide groove 12 and lower guide groove setting symmetrical above and below.The right baffle-plate 2
With right shell body 3 be respectively set the curved guiding surface 11 the left and right sides, the right baffle-plate 2, the right shell body 3 and the guiding
Cambered surface 11 is encircled into a fixture block installation space.
The upper fixture block 4 and the lower fixture block 5 are axially arranged in the fixture block installation space, 4 He of upper fixture block
The both ends of lower fixture block 5 are connected in the right baffle-plate 2 and right shell body 3, and the upper fixture block 4 and lower fixture block 5 being capable of edges respectively
About the 11 curved guiding surface deflection is to realize the clamping or release to drilling rod.
When the drilling rod of drilling machine is along radially across the fixture block installation space, and needs to clamp drilling rod, control on described
Fixture block 4 is downward, the lower fixture block 5 syncs up overturning, so that the clamping face of the upper fixture block 4 and the lower grip block 5
Clamping face close to clamp drilling rod.When needing to discharge drilling rod, control that the upper fixture block 4 is upward, the lower fixture block 5 is to similarly hereinafter
Step overturning, so that the clamping face of the clamping face of the upper fixture block 4 and the lower grip block 5 is separated to discharge drilling rod.
Particularly, the present invention in, the outside of the upper fixture block 4 be formed with the curved guiding surface 11 be in contact on contact
Cambered surface 42 is formed on the upper contacting surface 42 and protrudes from the upper contacting surface 42 and match with the upper guide groove 12
Upper fin 43, the upper fin 43 is embedded in the upper guide groove 12 and can slide up and down along the upper guide groove 12.It is right
It answers, the outside of the lower fixture block 5 is formed with the lower contacting surface (not shown) contacted with the curved guiding surface 11, connects under described
It is formed with the lower fin (not shown) for protruding from the lower contacting surface and matching with the lower guide groove in touching cambered surface, it is described
Lower fin is embedded in the lower guide groove and can slide up and down along the lower guide groove.
As it can be seen that the upper guide groove 12 and the upper fin 43 constitute between the upper fixture block 4 and the fixture block seat 1
Radial position limiting structure moves radially to guarantee that the upper fixture block 4 can not generate.Similarly, the lower guide groove with it is described under it is convex
Rib constitutes the radial position limiting structure between the lower fixture block 5 and the fixture block seat 1, to guarantee that the lower fixture block 5 can not produce
Life moves radially.Therefore, when radial generation surprisingly sliding of the drilling rod along grip slipper, the upper fixture block 4 and the lower fixture block 5 are not
Meeting generates radial compression to the right baffle-plate 1 or right shell body 2 of two sides.
In order to realize the rotation connection of the upper fixture block 4, the lower fixture block 5 and the right baffle-plate 2, right shell body 3.Some
In specific embodiment, the right baffle-plate 2 is equipped with the of the left end for being separately connected the upper fixture block 4 and the lower fixture block 5
One left mounting hole 21 and the second left mounting hole 22.The left end of the upper fixture block 4 is provided with the cooperated with the left mounting hole 21
One left connection shaft 45, the first left connection shaft 45 are penetrated to the described first left mounting hole 21.A left side for the lower fixture block 5
End is provided with the second left connection shaft (not shown) cooperated with the described second left mounting hole 22, and the second left connection shaft is worn
Enter to the described second left mounting hole 22.Correspondingly, the right shell body 3 is equipped with for being separately connected the upper fixture block 4 and institute
State the first right mounting hole (not shown) and the second right mounting hole (not shown) of the right end of lower fixture block 5.The right end of the upper fixture block 4
It is provided with the first right connection shaft with the described first right mounting hole cooperation, the first right connection shaft is penetrated to described first
In right mounting hole.The right end of the lower fixture block 5 is provided with (does not scheme with the second right connection shaft of the described second right mounting hole cooperation
Show), the second right connection shaft is penetrated to the described second right mounting hole.
To increase the frictional force between the upper fixture block 4, the lower fixture block 5 and drilling rod, prevent drilling rod in operation process
There is unexpected sliding, in certain embodiments, the clamping face of the upper fixture block 4 is recessed inwardly to form inserting groove 41, institute
It states and is plugged with friction pad 41 in inserting groove 44.The clamping face of the lower fixture block 5 is recessed inwardly to form lower inserting groove 51, described
Lower friction pad 51 is plugged in lower inserting groove 51.
The description with certain particularity detailed enough has been carried out to the present invention above.Ordinary skill in fields
Personnel are it should be understood that the description in embodiment is only exemplary, before without departing from true spirit and scope of the present invention
Put make it is all change all should belong to protection scope of the present invention.Scope of the present invention is by the power
What sharp claim was defined, rather than limited by the foregoing description in embodiment.
