Abstract
The utility model discloses a flange fixing device for welding a flange. The flange fixing device comprises a workbench (1), and is characterized in that stopping blocks (2) moving in the opposite direction are arranged on the workbench (1), the opposite ends of the stopping blocks (2) have the radian matched with the flange, and the other ends of the stopping blocks (2) are connected with air pumps (4) through connecting rods (3). When the flange fixing device of the structure is used, the stopping blocks can be pushed to a fixed position through the connecting rods and the action of the air pumps, therefore, the flange is clamped, the two ends of a welding position of the flange are fully combined, the strength of the welding position of the flange is guaranteed, and labor efficiency is greatly improved.
Description
Technical field
The utility model relates to a kind of machining tool, relates in particular to a kind of flange fixing device for welded flange.
Background technology
Flange is the blue flange of call again, is interconnective part between pipe and pipe, for the connection between pipe end; Also the flange that has the equipment that is used in to import and export, for the connection between two equipment.Perforation on flange, bolt is close to two flanges.Between flange, with liner, seal.Flange divides the flange that is threaded, welded flange and clip flange.Flange is all to use in pairs, and low pressure pipeline can be used screw thread silk acting flange, four kilograms of use welded flanges with upward pressure.Between two ring flanges, add sealing gasket, then use bolted.The flange thickness of different pressures is different, and the bolt that they use is also different.In the making of welded flange is produced, need to relate to welding.In welding process, due to the shape of flange itself, must guarantee that whole flange must fix and weld Wu great space, two ends relatively.In actual production, for large-sized flange, often do not accomplish this point.Thereby cause space, flange welding place larger, weld insufficient strength after welding.
Utility model content
The purpose of this utility model is that while solving large-sized flange welding, weld space causes greatly the problem of weld insufficient strength, and a kind of welding instrument is provided.
The technical solution adopted in the utility model is: a kind of flange fixing device for welded flange, comprise workbench, described workbench is provided with the stopper of move toward one another, the end in opposite directions of described stopper is provided with the radian suitable with flange, and the other end of described stopper is connected with air pump by connecting rod.
As further improvement of the utility model, described stopper is provided with sensor, and described sensor electrical connects air pump.
The beneficial effect that the utility model adopts is: use the instrument of this structure, can, by the effect of air pump, utilize connecting rod that stopper is pushed to fixed position, thereby clamping flange, make the abundant combination in two ends, flange welding place, guarantee the intensity at flange welding place, greatly improved production efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram.
Shown in figure: 1 workbench, 2 stoppers, 3 connecting rods, 4 air pumps.
The specific embodiment
Below in conjunction with Fig. 1, the utility model is described further.
As shown in Figure 1, for a flange fixing device for welded flange, comprise workbench 1, workbench 1 is provided with the stopper 2 of move toward one another, the end in opposite directions of stopper 2 is provided with the radian suitable with flange, and the other end of stopper 2 is connected with air pump 4 by connecting rod 3.Use the instrument of this structure, can utilize connecting rod that stopper is pushed to fixed position by the effect of air pump, thereby step up flange, make the abundant combination in two ends, flange welding place, guarantee the intensity at flange welding place.
In order to ensure stopper 2, can run to accurate location and guarantee the accurate combination in two ends, flange welding place, and the alteration of form of flange can be provided with to sensor by stopper 2, sensor electrical connects air pump 4.Use this kind of structure, broken away from the coarse problem of manual operation, and can be applicable to the flange of various models.
Those skilled in the art should know; protection scheme of the present utility model is not limited only to the above embodiments; can also on the basis of above-described embodiment, carry out various permutation and combination and conversion; under the prerequisite without prejudice to the utility model spirit, the various conversion that the utility model is carried out all drop in protection domain of the present utility model.
Claims (2)
1. the flange fixing device for welded flange, comprise workbench (1), it is characterized in that described workbench (1) is provided with the stopper (2) of move toward one another, the end in opposite directions of described stopper (2) is provided with the radian suitable with flange, and the other end of described stopper (2) is connected with air pump (4) by connecting rod (3).
2. a kind of flange fixing device for welded flange according to claim 1, is characterized in that described stopper (2) is provided with sensor, and described sensor electrical connects air pump (4).
