Description

Multi-angle fixed-position welding device for oil tank Technical Field The invention relates to the field of oil tank welding, in particular to an oil tank multi-angle positioning welding device. Background The oil tank is used as a core bearing component of a fuel supply system of power equipment such as automobiles, engineering machinery, agricultural equipment and the like, and the tightness, the structural coaxiality and the shape and position precision of welding molding of the oil tank directly determine the operation reliability and the service life of the equipment. The splicing welding of the tank body of the oil tank and the annular sealing welding of the tank body and the partition plates at the two ends are two core processes in the oil tank production flow, and have extremely high requirements on welding positioning accuracy and operation continuity. At present, research and development and optimization directions of an oil tank welding device in the industry are generally concentrated on clamping and positioning links of an oil tank body, and the problem of rigidity fixation in the welding process of a tank body is solved, so that the forming quality of a welding line of the tank body is guaranteed. However, as the requirements of downstream industries on the production efficiency, welding consistency and finished product qualification rate of the oil tank are continuously improved, the technical short plates and application limitations of the existing welding device are increasingly prominent. The existing oil tank welding device omits the accurate positioning design of the oil tank partition plate, and only pays attention to positioning and clamping of the oil tank body. In actual welding operation, the clamping, positioning and welding operation of the tank body of the oil tank can only be completed by the existing device, after the tank body is welded, synchronous positioning and welding operation of the partition plate cannot be completed at the same station, and the tank body must be transported to an independent special station for welding the partition plate, so that the positioning, clamping and welding procedures of the partition plate can be carried out. And at baffle welding station, the prior art adopts two-way outside centre gripping or stretches into the temporary positioning of mode realization baffle of location stock to the oil tank inside more, and this kind of locate mode is loaded down with trivial details not only operation flow, and clamping auxiliary time is long, is difficult to guarantee the axiality of baffle and box more, and the problem of baffle skew and welding gap inequality in the welding process very easily appears, and then causes quality defects such as welding seam shaping defect and oil tank seepage. In addition, in the working position separation type working mode in the prior art, the working procedure continuity of welding the tank body and welding the partition plate is thoroughly cut, and the continuous welding operation of the tank body and the partition plate of the oil tank cannot be realized. The process of transferring and repeated clamping of the box body among multiple stations not only greatly prolongs the production period of the product and reduces the overall production efficiency, but also can generate accumulated shape and position errors due to repeated switching of clamping references, thereby seriously affecting the overall shape and position precision and welding consistency of the oil tank. Meanwhile, the positioning mode of positioning the anchor rod stretches into the oil tank, the anchor rod and the workpiece are clamped easily after welding is finished, and the problem of difficult demoulding is caused, so that the operation difficulty and the production cost are further increased. Therefore, an oil tank welding technical scheme capable of realizing the continuous welding of the tank body and the partition board by combining the cooperative positioning of the tank body and the partition board is needed in the industry so as to solve a plurality of pain points existing in the prior art. Disclosure of Invention Based on the above, it is necessary to provide a multi-angle positioning welding device for an oil tank, aiming at the problems in the prior art.
