Abstract
The utility model relates to a tube vice which belongs to a clamping device for circular (or square-shaped) work pieces and comprises two groups of symmetrical frames, dental plates, and rotating handles which are connected into the integration through pin shafts, screw bolts, etc. The rotating handles are welded to the frames, the dental plates are fixed to the frame through connecting bolts, one ends of the frames are hinged with pin shafts, and the other ends of the frames are connected to swing bolts. The utility model is mainly used for the butt joint of steel pipes in petroleum bore well, has the advantages of flexible use and convenience, and solves the problems of the existing tube vice of dyssynergia, time wasting, and labor wasting in the butt joint of pipes. Compared with the existing tube vice, the work efficiency of the utility model is improved by 3 to 5 times.
Description
Tube vice of the present invention belongs to the clamping device of circle (or side) shape workpiece.
Generally adopt pipe vice as clamping device in present pipeline operation, particularly in oil drilling work, during the adjunction steel pipe, the steel pipe that always adopts pipe vice to clamp top docks and tightens with the steel pipe in the well in drilling well.In use very inconvenient, not only dumb, and time-consuming, effort, efficient is very low.
The objective of the invention is to design a kind of special fixture of pipe fitting, the pipe (or rod) of energy clamping different-diameter particularly can be operated than the workpiece of big shape in clamping.
This Tube vice has framework, dental lamina and the turning handle of two groups of symmetries, forms an integral body by bearing pin and bolt etc., and turning handle and framework weld together, and dental lamina is fixed on the framework by connecting bolt, and an end of framework is hinged with bearing pin, and the other end links to each other with the loose joint bolt.In order to satisfy instructions for use, its structural requirement has certain intensity and rigidity, for making the workpiece of clamp energy clamping different-diameter, on dental lamina (or framework), opened the through hole of several long strip types, utilize this hole that dental lamina front and back on framework are moved, according to the different thicknesses of caliber dental lamina is fixed and gone up in place.Can achieve the goal as long as change the dental lamina of different model as enlarging the caliber scope of application again.
Use this Tube vice, it is dexterous convenient not only to use, and can also overcome the shortcoming of original use pipe vice butt tube period of the day from 11 p.m. to 1 a.m dyssynergia, time-consuming, effort, compares with original use pipe vice, can increase work efficiency 3～5 times.
Description of drawings:
Figure one is the Tube vice structure chart.
Figure two is the C-C cutaway view of Tube vice structure chart.
Figure three, figure four are the dental lamina figure of different model.
1-hinge bearing pin among the figure, the 2-turning handle, the 3-dental lamina, 4-links connecting bolt, 5-framework, 6-loose joint bolt.
For implementing the present invention, this Tube vice adopts full steel structure, for ease of drawing materials and reducing cost, framework is welded by the channel-section steel bending, turning handle is selected cold-drawn or hot finished steel pipe for use, and turning handle and framework weldering are one, and dental lamina is selected for use No. 45 steel (or being better than steel No. 45) plate to cut out to cut and processed, the dental lamina mouth is processed into zigzag, and bolt and nut and bearing pin pin all adopt standard component.During use the loose joint bolt is untied, Tube vice is enclosed within buckles the loose joint bolt on the workpiece, fastening nut just is fixed on Tube vice on the workpiece firmly.Hold turning handle, just can make workpiece about under the vertical state, arbitrarily rotate and move up and down, with the purpose that realizes that the pipe fitting butt joint is installed, but both one man operations, also can the above compounding practice of two people.
