Background technology
At present, comparatively common clamping clip does not have the function of automatic centering, when causing grasping the different-diameter drilling tool at every turn, needs to regulate the control oil cylinder stroke by special entity drilling tool is accurately located; Simultaneously because clamping drilling tool external diameter difference needs the frequent clamping clip binding clip of changing.
Summary of the invention
The purpose of this utility model provides a kind of automatic centering formula drilling tool clamping clip, has solved the centering problem of pipe treatment facility in clamping different-diameter drilling tool process, and because clamping drilling tool external diameter difference needs the frequent problem of changing the clamping clip binding clip.
The technical scheme that the utility model adopted is, a kind of automatic centering formula drilling tool clamping clip, and the center line of clamping clip housing is provided with the automatic centering part, and the automatic centering part is the V-type shape, and the automatic centering part is connected with positional cylinder by the centralized positioning push rod; Respectively be provided with a pair of meshing gear train in the center line both sides of clamping clip housing, comprise meshing inboard gear and outboard gears separately, the V-type two ends of automatic centering part is connected with right backstay with left backstay respectively, left side backstay is separately installed with a checkout gear with right backstay and being connected of automatic centering part on the termination, the centralized positioning push rod passes between two inboard gears, and keeping meshing the connection simultaneously with two inboard gears, left backstay keeps meshing with the outboard gears of two pairs of gear trains respectively with right backstay and is connected; The link of left side backstay and automatic centering part is hinged with left side clamping binding clip, the left side backstay other end and left clamping cylinder are hinged, the piston rod head of left side clamping cylinder is hinged with the stage casing that a left side clamps binding clip, equally, the link of right backstay and automatic centering part is hinged with right clamping binding clip, the right backstay other end and right clamping cylinder are hinged, and the piston rod head of right clamping cylinder is hinged with the stage casing of right clamping binding clip.
The beneficial effects of the utility model are, have solved the centering problem of pipe treatment facility in clamping different-diameter drilling tool process, avoid each because the drilling tool diameter variation causes the pipe treatment facility to need the trouble of regulating repeatedly to the well head center time; Especially, adopt the general binding clip of special construction, avoid changing the clamping clip binding clip of different model, simplify the clamping clip structure, save service working time, increase work efficiency greatly owing to the drilling tool diameter variation.
Description of drawings
Fig. 1 is the structural representation of the utility model device;
Fig. 2 is that the automatic centering of the utility model device clamps principle schematic;
Fig. 3 is the working state figure of the utility model device when adopting one-sided clamping clip clamping drilling tool.
Among the figure, 1. right clamping cylinder, 2. left clamping cylinder, 3. automatic centering part, 4. control device, 5. clamping clip housing, 6. checkout gear, 7. a left side clamps binding clip, the 8. right binding clip that clamps, 9. positional cylinder, 10. left backstay, 11. right backstays, 12. centralized positioning push rod, 13. inboard gear, 14. outboard gears, 15. drilling tools.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
As Fig. 1, Fig. 2, the structure of the utility model device is, the left-right symmetry center line of clamping clip housing 5 is provided with the centralising device of gear ﹠ rack structure, automatic centering part 3 in the centralising device is the V-type shape, be beneficial to drilling tool and enter into V-type bottom portion of groove location, automatic centering part 3 is connected with positional cylinder 9 by centralized positioning push rod 12; Respectively be provided with a pair of meshing gear train in the center line both sides of clamping clip housing 5, comprise meshing inboard gear 13 and outboard gears 14 separately, the V-type two ends of automatic centering part 3 is connected with right backstay 11 with left backstay 10 respectively, left side backstay 10 is separately installed with a checkout gear 6 with right backstay 11 and being connected of automatic centering part 3 on the termination, centralized positioning push rod 12 passes between two inboard gears 13, and keeping meshing the connection simultaneously with two inboard gears 13, left backstay 10 keeps meshing connections with the outboard gears 14 of two pairs of gear trains respectively with right backstay 11; Left side backstay 10 is hinged with left side clamping binding clip 7 with the link of automatic centering part 3, left side backstay 10 other ends and left clamping cylinder 2 are hinged, the piston rod head of left side clamping cylinder 2 is hinged with the stage casing that a left side clamps binding clip 7, equally, right backstay 11 is hinged with right clamping binding clip 8 with the link of automatic centering part 3, right backstay 11 other ends and right clamping cylinder 1 are hinged, and the piston rod head of right clamping cylinder 1 is hinged with the stage casing of right clamping binding clip 8.Right clamping cylinder 1, left clamping cylinder 2, positional cylinder 9 all are connected with control device 4, accept the unified control of coordinating.
With reference to Fig. 1, Fig. 2, the operation principle of the utility model device is that entire mechanism is controlled by three oil cylinders, is respectively the left clamping cylinder 2 of the right clamping cylinder 1 of the positional cylinder 9 of automatic centering mechanism, right clamping clip, left clamping clip.The process of whole clamping drilling tool is divided into two steps, after drilling tool is placed into clamping clip, form interlinked mechanism by gear pair between left and right clamp mechanism and the automatic centering mechanism, in left and right clamp mechanism end checkout gear 6 is set, whether meet the requirements of the center to detect the different-diameter drilling tool, and cut off positional cylinder 9 fuel feeding rapidly with this signal.Secondly, after drilling tool was pulled to suitable position, the clamping cylinder of left and right clamp mechanism was started working, and promoted clamping clip and held drilling tool tightly, thereby reach the purpose that drilling tool is accurately located and clamped.
Three groups of backstays and two groups of identical gear drives, the direction of motion that has guaranteed left and right backstay and centralized positioning push rod remains consistent, and checkout gear is set in left and right backstay end, reach by this and make the drilling tool self-centering and detect the purpose whether drilling tool arrives the center.Universal clamp clencher binding clip is suitable for the drilling tool diameter range , when the bigger drilling tool of clamping diameter, left and right clamping clip can act on simultaneously, holds drilling tool tightly.
As Fig. 3, what show among the figure is only to use the right side clamping clip to clamp the view of drilling tool, when the drilling tool diameter of clamping hour, realize that by the oil circuit that cuts off the control oil cylinder that leads to a left side or right clamp mechanism single clamping clip clamps drilling tool, only uses one-sided clamping clip to come the clamping drilling tool.
