Preferably, in above-mentioned clamping device of the present invention, described tooth bar moves back and forth along first direction under the driving of described driving oil cylinder.
Preferably, in above-mentioned clamping device of the present invention, the reciprocating motion of described tooth bar will drive described the first and second gears rotation, and then drive described the first and second jaws and move up in the second party vertical with described first direction, the moving direction of wherein said the first jaw and described the second jaw is respect to one another.
Preferably, in above-mentioned clamping device of the present invention, a side respect to one another of described the first jaw and described the second jaw is an inner fovea part.
Preferably, in above-mentioned clamping device of the present invention, also comprise: shell structure coats a part, tooth bar and first and second gears of described the first and second jaws.
Preferably, in above-mentioned clamping device of the present invention, the inboard of described shell structure has a slide rail, moves up in described second party in order to guide described the first and second jaws.
The characteristics of clamping device of the present invention mainly are: 1. self-centering, i.e. and no matter drilling rod or the sleeve pipe of which kind of diameter, its axial line all is the same with the relative distance of clamping device after clamping; 2. mechanism reliability is high, adopts the mechanically type of belt drive of very ripe rack-and-pinion.
Should be appreciated that the above generality of the present invention is described and the following detailed description all is exemplary and explanat, and be intended to the further explanation that the invention provides for as claimed in claim.
Description of drawings
Comprise that accompanying drawing is for providing the present invention further to be understood, they are included and are consisted of the application's a part, and accompanying drawing shows embodiments of the invention, and play the effect of explaining the principle of the invention with this manual.In the accompanying drawing:
Fig. 1 schematically shows the structure according to a preferred embodiment of clamping device of the present invention.
The specific embodiment
Now with embodiments of the present invention will be described by referring to the drawings in detail.Now will be in detail with reference to the preferred embodiments of the present invention, its example is shown in the drawings.In the case of any possible, in institute's drawings attached, will represent with identical mark same or analogous part.In addition, although employed term is to select from public term among the present invention, but some mentioned terms may be that the applicant selects by his or her judgement in the manual of the present invention, and its detailed meanings illustrates in the relevant portion of the description of this paper.In addition, require not only by employed actual terms, but also will understand the present invention by the meaning that each term contains.
Fig. 1 schematically shows structure according to a preferred embodiment of the present invention.In the embodiment shown in fig. 1, clamping device 100 of the present invention mainly comprises: drive oil cylinder 101, tooth bar 102, the first gear 103, the second gear 104, the first jaw 105, the second jaw 106 and shell structure 107.
As shown in the figure, tooth bar 102 is connected with driving oil cylinder 101.The first and second gear 103-104 are arranged at respectively the left and right sides of tooth bar 102.This first and second gear 103-104 respectively with the left and right sides of tooth bar 102 on the tooth mouth be meshed.The first and second jaw 105-106 are positioned opposite to each other.The side of the first and second jaw 105-106 is to mesh with above-mentioned the first and second gear 103-104 respectively with the band tooth limit of tooth limit and this first and second jaw 105-106.In addition, a side respect to one another of the first jaw 105 and the second jaw 106 is an inner fovea part, so that the drilling rod of clamping tubulose or sleeve pipe.
