Annular welding system with high universality and quick and accurate positioning for pressure vessels

Abstract

The invention discloses an annular welding system with high universality and quick and accurate positioning for pressure vessels. The annular welding system comprises a centering device, a supporting device arranged between a first supporting frame and the centering device, pressure vessel samples arranged on the centering device and the supporting device, a centring device connected to the supporting device and clamping devices arranged on the two sides of the pressure vessel samples. By arranging the centering device, the pressure vessel samples can be centered at first; by arranging the supporting device, the pressure vessel samples with different outer diameters can be rapidly fixed; by arranging the centring device, a first guide rod piece, a second guide rod piece, a centring assembly and a fourth connecting rod, so that the central axis of each pressure vessel sample can be quickly found through an intersection point of two vertical bisectors; by arranging the clamping devices, so that the side surfaces of the pressure vessel samples can be better clamped; and the pressure vessel samples of different models can be quickly supported, centered and positioned.

Description

technical field [0001] The invention belongs to the field of welding technology, and in particular relates to an annular welding system for pressure vessels with strong versatility and fast and accurate positioning. Background technique [0002] With the continuous progress of industrial processing and manufacturing, welding technology, as an important category of processing technology, plays an important role in the processing of mechanical parts. For the special category of pressure vessels, welding is more difficult than welding. Other parts are more difficult to weld, and it is necessary to improve the original welding device to improve the convenience of welding; when the traditional welding technology exists when welding pot-shaped parts, it is not convenient to fix parts with a certain radian , it is difficult to fix canned parts with different outer diameters, so it is even more impossible to quickly and universally fix canned parts with different outer diameters, an...

[0002] With the continuous progress of industrial processing and manufacturing, welding technology, as an important category of processing technology, plays an important role in the processing of mechanical parts. For the special category of pressure vessels, welding is more difficult than welding. Other parts are more difficult to weld, and it is necessary to improve the original welding device to improve the convenience of welding; when the traditional welding technology exists when welding pot-shaped parts, it is not convenient to fix parts with a certain radian , it is difficult to fix canned parts with different outer diameters, so it is even more impossible to quickly and universally fix canned parts with different outer diameters, and it is not convenient to automatically position the central axis of cans with different outer diameters, and the existing The positioning of the same arc is also realized by the chuck, and the positioning speed is slow, and it takes a long time to calibrate the positioning, which greatly affects the welding speed and welding accuracy
