Abstract
The utility model discloses a tool for hermetically connecting a rotary fire hydrant. The tool comprises an expansion taper sleeve mounted on a working platform and adopting a crossed structure; a positioning and guiding plane is arranged on the expansion taper sleeve in the horizontal direction; a hollow cylinder is arranged on the expansion taper sleeve in the vertical direction; the section of the inner part of one end, far from the working platform, of the cylinder is tapered; a taper core is mounted in the position of the tapered structure on the expansion taper sleeve, and has an inclination that is the same as that of the tapered section; one end of a connecting rod is mounted at the bottom of the taper core, and the other end of the connecting rod is mounted on an air cylinder below the working platform. The tool has the advantages that the mounting height of the expansion taper sleeve is adjusted through an adjustable nut to adapt to the requirement of workpieces of different heights; meanwhile, the workpiece is pressed by the expansion taper sleeve through the vertical pressure applied on the taper core by the air cylinder, so that the workpiece achieves the axial movement in mounting, and the workpiece connected coaxiality requirement is ensured.
Description
Technical field
The utility model relates to a kind of frock being tightly connected for rotary-type fire hydrant.
Background technology
Rotary-type fire hydrant is a kind of indoor fire-fighting water facilities, for supplying water or directly connect and put out a fire with water band, hydraulic giant to fire fighting truck, is the special facilities that indoor fire-fighting supplies water.General fire_fighting pipe network pressure is 2.4MPa, and fire hydrant, as important fire fighting supply facility, is had higher requirement to its sealing property.The existing rotary-type fire hydrant manufacture craft that is tightly connected, labour intensity is large, and cannot guarantee the axiality connecting is installed, and defect rate is high, easily breaks down in actual use, thereby has certain potential safety hazard.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of frock being tightly connected for rotary-type fire hydrant for problems of the prior art, its objective is and makes workpiece realize axially-movable in connection process is installed, and has guaranteed axiality requirement.
The technical solution of the utility model is that the frock that this kind is tightly connected for rotary-type fire hydrant comprises the expansion tapered sleeve being arranged on workbench, the profile of described expansion tapered sleeve is decussate texture, horizontal direction is positioning and guiding plane, vertical direction is the cylinder of hollow shape, cylinder is away from one end of workbench, its inner section is shaped as taper, the cone core with tapered cross-section with same slope is arranged on the pyramidal structure position that expansion cone puts, one end of connecting rod is arranged on the bottom of cone core, and the other end is arranged on the cylinder that is positioned at workbench below.
One end that described expansion cone puts away from pyramidal structure is provided with external screw thread, and by coordinating and be arranged on workbench with adjustable nut, by regulating adjustable nut, adjusts the relative altitude between expansion tapered sleeve and workbench.
There is the frock that this kind of said structure be tightly connected for rotary-type fire hydrant and by adjustable nut, expansion tapered sleeve and workbench are linked together, can be by the setting height(from bottom) of adjustable nut adjustment expansion tapered sleeve, to adapt to the requirement of differing heights workpiece; Meanwhile, during work by cylinder the pressure at right angle to cone core, the tapered sleeve turgor pressure clamping of workpieces that makes to expand, makes workpiece realize when mounted axially-movable, guarantees the axiality requirement that workpiece connects.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
In Fig. 1,1: workbench; 2: expansion tapered sleeve; 3: cone core; 4: connecting rod; 5: cylinder; 6: adjustable nut; 7: positioning and guiding plane; 8: the first workpiece; 9: second workpiece; 10: connect lining; 11: trip bolt.
The specific embodiment
Fig. 1 is the structural representation of the frock that is tightly connected in rotary-type fire hydrant of the utility model, the frock that this kind is tightly connected for rotary-type fire hydrant comprises the expansion tapered sleeve 2 being arranged on workbench 1, the profile of described expansion tapered sleeve 2 is decussate texture, horizontal direction is the cylinder that positioning and guiding plane 7 vertical direction are hollow shape, cylinder is away from one end of workbench 1, its inner section is shaped as taper, the cone core 3 with tapered cross-section with same slope is arranged on the pyramidal structure position on expansion tapered sleeve 2, one end of connecting rod 4 is arranged on the bottom of cone core 3, the other end is arranged on the cylinder 5 that is positioned at workbench 1 below.
One end away from pyramidal structure on expansion tapered sleeve 2 is provided with external screw thread, and by coordinating and be arranged on workbench 1 with adjustable nut 6, by regulating adjustable nut 6, adjusts the relative altitude between expansion tapered sleeve 2 and workbench 1.
The using method of the frock that this kind is tightly connected for rotary-type fire hydrant is:
1) the first workpiece 8 processing is arranged in frock, and positions by 7 pairs of the first workpiece 8 of the positioning and guiding plane on expansion tapered sleeve 2;
2) open the switch of cylinder 5, cylinder 5 moves vertically downward by connecting rod 4 band mantle cores 3, by the cone outer rim inclined-plane of core 3 and the taper surface effect of expansion tapered sleeve 2 inside, holds out against expansion tapered sleeve 2, and the first workpiece 8 is fixed in frock;
3) second workpiece 9 is connected with the first workpiece 8 by connecting lining 10, and rotate the first workpiece 8 and second workpiece 9, test verticity;
4) verticity qualified after, by trip bolt 11, the first workpiece 8 and second workpiece 9 are linked together, the switch of shifter cylinder 5, unloads the first workpiece 8 and the second workpiece 9 that complete connection.
There is the frock that this kind of said structure be tightly connected for rotary-type fire hydrant and by adjustable nut, expansion tapered sleeve and workbench are linked together, can be by the setting height(from bottom) of adjustable nut adjustment expansion tapered sleeve, to adapt to the requirement of differing heights workpiece; Meanwhile, during work by cylinder the pressure at right angle to cone core, the tapered sleeve turgor pressure clamping of workpieces that makes to expand, makes workpiece realize when mounted axially-movable, guarantees the axiality requirement that workpiece connects.
