Abstract

Изобретение относитс к сварке, в частности к устройствам дл сборки и сварки обечайки из сегментов. Цель изобретени .- повышение точности сборки. Устройство со- дерхмт основании 1, в направл ющих которого перемещаетс тележка 4. На стойках 2 и 3 осноэанил подвижно размещены прижимна балка 6 и вал 9. На прижимной балке смонтирована установка 8. На валу 9 размещены пневмогидравлическа подвод ща муфта, делительный диск, подкладные 12 и формообразующие 14 балки и планшайба. Дл обеспечени сборки и сеар- ки обечаек двух типоразмеров цилиндры 13 и 15, на которых установлены соответственно подкладные 12 и формообразующие 14 балки, выполнены двухкамерными. Взаимна фиксаци прижимной б и подкладных 12 балок в положени х сварки осуществлена путем взаимодействи упоров делительного диска, жестко посаженного на валу 9, с конечным выключателем мгновенного действи . Фиксаци сегментов обечайки осуществлена пневмоприжимами 16. Съем сваренной обечайки осуществлен с помощью тележки с подъемной платформой. Благодар такой конструкции повышаетс производительность и точность работы устройства , 5 ил.The invention relates to welding, in particular to devices for assembling and welding a shell of segments. The purpose of the invention. Improving the accuracy of the assembly. The device contains the base 1, in the guides of which the trolley 4 moves. On the uprights 2 and 3 of the osneoanil, the pressure beam 6 and the shaft 9 are movably placed. The installation 8 is mounted on the pressure beam. 12 and formative 14 beams and faceplate. To ensure the assembly and drilling of the shells of two sizes, cylinders 13 and 15, on which the liners 12 and the shaping 14 beams, respectively, are made, are made in two chambers. Mutual fixation of the clamping b and backing beams in the welding positions was carried out by the interaction of the stops of the dividing disc, firmly seated on the shaft 9, with the instantaneous limit switch. Fixing the segments of the shell made pneumatic clamps 16. Erase the welded shell made using a trolley with a lifting platform. Thanks to this design, the productivity and accuracy of the device is improved, 5 or more.
