Abstract
The utility model discloses a kind of jig, comprise chuck and be arranged on the chuck in chuck, the periphery of described chuck is provided with some positioning strips, and described positioning strip is fixedly connected with described chuck, and each described positioning strip is all removably connected with pressing plate.By utilization of the present utility model, overcoming prior art jig can not clamp large-size pipe, and clamping easily produces the defect loosened.And maintain original function simultaneously, also can clamp by the small-sized pipe fitting of centering, thus coupling various sizes pipe fitting.
Description
Technical field
The utility model relates to a kind of jig.
Background technology
In existing pipe fitting welding, usually use robot and weld.Generally by jig, pipe fitting is clamped.But existing chuck can not well clamp for large-scale pipe fitting.Because the claw movable distance of chuck itself is limited, the position making existing claw usually cannot move to card to establish.And large-size pipe easily loosens when chuck is rotated, welding quality is caused to be deteriorated.
Utility model content
The technical problems to be solved in the utility model can not clamp large-size pipe to overcome prior art jig, and clamping easily produces the defect loosened, and provides a kind of jig.
The utility model solves above-mentioned technical problem by following technical proposals:
A kind of jig, comprise chuck and be arranged on the chuck in chuck, its feature is, the periphery of described chuck is provided with some positioning strips, and described positioning strip is fixedly connected with described chuck, and each described positioning strip is all removably connected with pressing plate.For large-scale pipe fitting, chuck now cannot be fixed, and can be fixed by pressing plate, pushes down the flange of pipe fitting.
Preferably, described positioning strip is provided with some locating holes, described pressing plate is connected with described locating hole by threaded fastener.By the setting of locating hole, can adapt to the pipeline of sizes,
Preferably, described pressing plate comprises pedestal and pressure tongue, and described pedestal is connected with described locating hole by threaded fastener.
Preferably, the quantity of described positioning strip is three.By three-point fix, can guarantee that pipeline center is positioned at chuck center, so that robot further processes.
Preferably, the quantity of described pressing plate is three pieces.
Preferably, described chuck comprises a base and is arranged on the claw on described base.
Preferably, the quantity of described claw is three.
Preferably, described claw is connected with described base sliding.
In the utility model, above-mentioned optimum condition can be combined on the basis meeting this area general knowledge, obtains each preferred embodiment of the present utility model.
Positive progressive effect of the present utility model is: by utilization of the present utility model, and overcoming prior art jig can not clamp large-size pipe, and clamping easily produces the defect loosened.And maintain original function simultaneously, also can clamp by the small-sized pipe fitting of centering, thus coupling various sizes pipe fitting.
Accompanying drawing explanation
Fig. 1 is the perspective view of the utility model preferred embodiment.
Fig. 2 is the test structure schematic diagram of the utility model preferred embodiment.
Fig. 3 is the plan structure schematic diagram of the utility model preferred embodiment.
Detailed description of the invention
Enumerate preferred embodiment below, and come by reference to the accompanying drawings clearlyer intactly the utility model to be described.
As Figure 1-3, the present embodiment is a kind of jig, the chuck comprising chuck 3 and be arranged in chuck 3.
The claw 22 that described chuck comprises a base 21 and is arranged on base 21.The quantity of claw 22 is three.These three claws 22 preferably can distribute apart from one another by 120 degree.Claw 22 can clamp pipe fitting from outside, also can prop up outward from pipe fitting inboard.
Claw 22 in the enterprising line slip of base 21, thus can adapt to the change of the size of the pipe fitting in certain limit.But the displacement of claw 22 is limited, then need to be fixed by pressing plate 12 to large-sized pipe fitting.
As illustrated in fig. 1 and 2, the periphery of chuck is provided with three positioning strips 11, and positioning strip 11 is fixedly connected with chuck 3.Be generally welding.Each positioning strip 3 is all removably connected with pressing plate 12.For large-scale pipe fitting, claw 22 now cannot be fixed, and can be fixed, push down the flange of pipe fitting by pressing plate 12.
Positioning strip 11 is provided with some locating holes at a certain distance, and pressing plate 12 is connected with locating hole by threaded fastener 13.By the setting of locating hole, can adapt to the pipeline of sizes,
Further, pressing plate comprises pedestal 111 and pressure tongue 112, and pedestal 111 is connected with locating hole by threaded fastener 13.
The same with the quantity of claw 22, the quantity of positioning strip 11 is three, to become mutually 120 degree of layouts.By three-point fix, can guarantee that pipeline center is positioned at chuck 3 center, so that robot further processes.
In the utility model, above-mentioned optimum condition can be combined on the basis meeting this area general knowledge, obtains each preferred embodiment of the present utility model.
Although the foregoing describe detailed description of the invention of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection domain of the present utility model is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present utility model and essence, can make various changes or modifications to these embodiments, but these change and amendment all falls into protection domain of the present utility model.
