Embodiment Construction
[0014] join figure 1 , a positioning tool for welding large-diameter circularly arranged bending pipes, including a workbench 1, upper 2, and lower 3 positioning plates, said workbench 1 is provided with several guide posts 4, and said lower positioning The plate 3 is slidably fitted and fixed on the guide post 4, the upper positioning plate 2 is slidably fitted on the guide post 4, and the two sides above the workbench 1 are respectively equipped with a cylinder 5, and the end of the piston rod of the cylinder 5 is It is fixedly connected with the upper positioning plate 2, and the upper positioning plate 2 is pushed to slide up and down along the guide column 4. The upper 2 and lower 3 positioning plates are arranged in a circular arrangement with mutually corresponding openings 6 of the same size. The opening 6 is used to place and position a straight pipe 7 for welding.
[0015] When welding circularly arranged bent pipes, first insert the circularly arranged straight pip...

The invention discloses a locating frock for welding annularly arranged large-diameter bent pipelines, which comprises a working platform and upper and lower locating plates; the working platform is provided with a plurality of guide columns; the lower locating plate is slidingly sleeved and fixed to the guide columns, while the upper locating plate is slidingly sleeved to the guide columns; cylinders are mounted at the two sides of the working platform respectively; end parts of piston rods of the cylinders are fixedly connected with the upper locating plate; the upper locating plate is pushed to slide up and down along the guide columns; openings which are corresponding to each other and have the same sizes are annularly arranged on the upper and lower locating plates; and straight pipes for welding are placed and located in the openings. The locating frock is simple in structure and convenient to manufacture, and can accurately locate the processed pipelines and ensure that the deviation may not be exceeded in the continuous bending forming process.
Description
technical field [0001] The invention relates to a positioning device, mainly a positioning tool for welding of large-caliber circularly arranged bent pipes. Background technique [0002] It is difficult to accurately form multiple large-diameter bent pipes when they are continuously bent at the same time. A positioning device with precise positioning is required to accurately position the two ends of the pipe without exceeding the deviation. At the same time, it is also necessary to ensure that the positions of the pipe fittings are consistent. will exceed the deviation. The existing large-diameter bent pipes cannot guarantee the positional deviation between the pipes when they are welded in a circular arrangement. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a positioning tool for the welding of large-diameter circularly arranged bending pipes, which has a simple structure and is easy to manufacture, and can...
