The method has higher requirements on the blanking size precision, the operation and welding level of workers, if the operation is not proper, the flange is easily out of alignment in inclination angle, the position of the mounting plate is deviated, unqualified products are caused, the reworking and the repairing are needed, the time and the labor are wasted, and the yield is low.
Disclosure of Invention
The utility model provides a technical problem overcome prior art not enough, provide one kind and can be used for oil tank flange and mounting panel location assembly welding platform.
The utility model discloses a technical scheme be one kind and be used for oil tank flange and mounting panel location assembly welding platform, the welding position piece on the bottom plate, locating piece and oil tank bottom plate clearance fit, locating piece periphery distribution welding pillar, the pillar distributed position is the same with the oil tank mounting panel position that will weld on the bottom plate, bottom plate one end welding support, mounting flange locating plate on the support, flange locating plate processing big through-hole and bolted connection hole.
The positioning block consists of two sections of straight line plates and two sections of circular arc plates. The straight line plate and the circular arc plate are processed with steps. The pillar is provided with a positioning pin hole, and a positioning pin is arranged in the positioning pin hole.
And welding a positioning block on the bottom plate, welding a support according to the position of the mounting plate on the oil tank, welding a support at one end of the bottom plate, processing steps of a linear plate and an arc plate in a numerical control processing center after welding, then processing and supporting the upper surface, the positioning pin hole and the upper surface of the support, and positioning and fixing the flange positioning plate on the support, thereby completing the processing and assembly of the assembly and welding platform. When the oil tank positioning device is used, the oil tank is firstly hung on the positioning block and is positioned by the outer surface of the bottom plate of the oil tank. Then positioning through a large through hole on a flange positioning plate, fixing an oil tank flange on the flange positioning plate through a bolt and a nut, welding the flange on the oil tank, and disassembling a connecting bolt and a nut; and then the mounting plate is placed on the pillar, the positioning pin hole on the pillar is provided with the positioning pin which is matched and positioned with the positioning hole on the mounting plate, and the mounting plate is welded on the oil tank.
The beneficial effects of the utility model are that through a tank location, accomplished the group of oil tank flange and oil tank mounting panel respectively to the welding, after welding the oil tank, flange angle and position are accurate, and the mounting panel position is also accurate, has reduced the rate of reprocessing, and the yield is high, workman convenient operation, labour saving and time saving.
