With the continuous progress of technology and the continuous development of industrial production, the device suitable for welding the cylinder on the pressure vessel is also continuously improved and optimized. In early days, pressure vessel welding was typically performed by manual arc welding or gas shielded welding. Although the manual arc welding is suitable for welding at various positions, the welding quality is unstable, and the defects of air holes, slag inclusion and the like are easy to occur; although the gas shielded welding has the advantages of high welding speed and good quality, the gas shielded welding has higher equipment cost and limited application range. With the continuous development of technology, advanced welding methods such as submerged arc welding and argon arc welding are gradually applied to welding of pressure vessels. The welding methods have the advantages of high welding speed, good quality, attractive weld formation and the like, and become the main method for welding the pressure vessel. Meanwhile, with the development of automation technology, automatic welding machines are also increasingly applied to welding of pressure vessels. The automatic welding machine adopts the mechanical arm and the welding head to weld, has the advantages of high welding speed, stable quality, high production efficiency and the like, and becomes a main welding method for mass production of pressure vessels. With the development of the digitization technology, the digitization welding technology is also gradually applied to welding of pressure vessels. The digital welding technology adopts a digital control system and an advanced sensor technology, so that high-precision welding operation can be realized, and welding quality and production efficiency are improved.

In the above patent document, CN202010412210.7, which specifically refers to positioning by a positioning pin, requires additional processing of a connecting strip and additional installation of the positioning pin, which is inconvenient and not fast; CN202320448035.6 therein, which discloses positioning by pressing plates, needs to be manually completed for pressing operation of the pressing plates, and positioning force of each pressing plate may be different, resulting in inaccurate positioning; therein CN202310597755.3, which discloses a positioning structure that does not effectively position both ends of the longitudinal seam. In addition, since the pressure vessel is formed after bending the metal plate, all the metal plate has a repulsive force when welding the longitudinal joint, which may expand the longitudinal joint, resulting in inaccurate welding. Finally, when welding, different welding requirements are often faced, so that the width of the gaps between the welded longitudinal joints is changed, and the width between the longitudinal joints cannot be changed according to the different welding requirements in the above patent, so that the different welding requirements are met. In addition, the pressure vessels are large vessels, and the thickness of the plates is very thick, so that when welding longitudinal seams, the inner welding edge line and the outer welding edge line are difficult to contact together at the same time, and therefore, the complete welding is difficult to realize during welding.

(III) beneficial effects
Compared with the prior art, the invention provides a device suitable for welding a cylinder on a pressure container, which has the following beneficial effects:
1. the device for welding the cylinder body on the pressure vessel is matched with the first positioning module and the second positioning module. When the cylindrical part to be welded is still on the preparation support, the first cylinder operates to push the driving block to move to two sides, the driving block moving to two sides further drives the upper end of the first blocking block to rotate to the middle, and the first blocking block can block the front end of the cylindrical part to be welded at the moment, so that the front end of the cylindrical part to be welded is positioned on the welding support. After the front end of the tubular piece to be welded is blocked by the first blocking block, the adjusting cylinder at the rear end of the tubular piece to be welded operates, so that the second blocking block extends backwards, then the rotating motor works, the second blocking block rotates towards the middle, and finally the second cylinder is retracted, so that the second blocking block abuts against the rear end of the tubular piece to be welded, the tubular piece to be welded is completely positioned on the welding bracket, and the position of the longitudinal seam is accurately positioned. Thereby the end of having reached the longitudinal joint carries out accurate location for welding stroke is equivalent with longitudinal joint length, reduces the effect of idle stroke.
2. The cylinder welding device for the pressure vessel is matched with the cylinder, the pinch roller and the guide rod. After the cylindrical piece to be welded is pushed into the welding bracket by the pushing block, the cylindrical piece to be welded formed by bending the metal plate still has certain elasticity, and at the moment, the longitudinal seam of the cylindrical piece to be welded has the risk of bouncing open towards two sides. Firstly, deformation caused by elasticity of the guide rod can be reduced through blocking of the guide rod, meanwhile, the pressing wheel moves downwards through the adjusting cylinder, the pressing wheel is uniformly pressed at the upper end of the cylindrical part to be welded, the cylindrical part to be welded contracts towards the longitudinal joint, elastic deformation of the cylindrical part to be welded is reduced, and welding accuracy is guaranteed. Therefore, the device for limiting the rebound of the metal plate is achieved, the longitudinal seam is ensured not to be enlarged due to the rebound of the metal plate, and the welding accuracy is reduced.
3. The cylinder welding device for the pressure vessel is matched with the cylinder, the pinch roller and the guide rod. After the cylindrical member to be welded is pushed into the welding bracket by the pushing block, the width between the longitudinal slits needs to be adjusted according to the shape and size of the cylindrical member to be welded, the thickness of the metal plate, the welding requirement, and the like. Therefore, after the cylindrical part to be welded is pushed into the welding bracket by the pushing block, the pressing wheel positioned at the upper part of the cylindrical part to be welded moves downwards under the action of the adjusting cylinder, after the pressing wheel contacts the cylindrical part to be welded, if the distance between the longitudinal seams is relatively smaller according to the welding requirement, the adjusting cylinder can further move downwards, so that the longitudinal seams are compressed towards the middle, the width between the longitudinal seams is reduced, after the width between the longitudinal seams reaches the requirement, the pressing wheel stops pressing downwards, and then the welding of the longitudinal seams is started. If the distance between the longitudinal seams is relatively large according to the welding requirement, the pressure wheel can move upwards by adjusting the air cylinder, the longitudinal seams can stretch to two sides due to the elastic deformation of the tubular piece to be welded, the width between the longitudinal seams is large, after the width between the longitudinal seams reaches the requirement, the pressure wheel stops rising, and then the welding of the longitudinal seams is started. And because of the large thickness of the plates of the pressure vessel, the two welding edges of the longitudinal seam are difficult to be effectively combined together during welding. Through the effect of adjusting the module, can make to the thicker pressure vessel of panel, also can let the inside and outside welding boundary line between the longitudinal joint laminate together completely. Therefore, the effect that the width between the longitudinal joints can be changed according to different welding requirements to meet different welding requirements is achieved.

A stopper 711 is provided on one end of the welding table 71 near the preparation stand 12, and the stopper 711 has a wedge shape with one end being narrow and the other end being gradually widened. The stopper 711 is provided at an intermediate position of the welding table 71. When the cylindrical member 5 to be welded is pushed from the preparation stand 12 to the welding stand 11, at this time, since there is one longitudinal slit 51, and the position of the longitudinal slit 51 should be at the bottommost part at the time of welding, at this time, the cylindrical member 5 to be welded at the preparation stand 12 is rotated to the position where the longitudinal slit 51 is at the bottommost part, but there is still a certain deviation, and during the advancing, the narrower end of the stopper 711 is inserted into the longitudinal slit 51, so that the cylindrical member 5 to be welded is positioned smoothly during the advancing.
The discharging module 8 comprises a base 81, the base 81 is arranged on the side surface of the rear end of the guide rod 63, a left moving member 85 and a right moving member 85 are arranged on the base 81, a front moving member 83 and a rear moving member 83 are arranged on the left moving member and the right moving member 85, a discharging pushing block 82 is arranged on the front moving member and the rear moving member 83, and a pushing motor 84 is arranged on the front moving member and the rear moving member 83. When the tubular member 5 to be welded is welded, it is necessary to discharge the welded part, and at this time, since the temperature of the part just welded is high, manual contact is not possible. The left and right moving member 85 on the base 81 moves to the welded part until the discharge pushing block 82 is located at the rear of the part, then the pushing motor 84 starts to operate, so that the front and rear moving member 83 moves forward and drives the discharge pushing block 82 thereon to move forward, and after the discharge pushing block 82 contacts the welded part, the part can be pushed forward until the part is completely pushed out of the welding bracket 11, and the next process is performed.
The working principle is that when the cylindrical piece 5 to be welded on the preparation bracket 12 needs to be propped against the welding bracket 11 for welding, the advancing motor 23 starts to operate so as to move to the tail part of the pushing track 24, the propping cylinder 21 starts to operate at the moment, the pushing block 22 is pushed downwards so that the pushing block 22 is lower than the upper edge of the cylindrical piece 5 to be welded, the advancing motor 23 starts to operate at the moment so that the pushing block 22 moves forwards and finally butts against the tail part of the cylindrical piece 5 to be welded, and then the cylindrical piece 5 to be welded is pushed to move forwards until the cylindrical piece 5 to be welded is pushed into the welding bracket 11.
Before being pushed into the welding bracket 11, the first cylinder 32 starts to operate, and the driving block 33 is pushed to move from the middle to the two sides, so that the lower half part of the first blocking block 31V shape is further driven to rotate outwards, and accordingly the upper half part of the first blocking block 31V shape is enabled to rotate inwards, the upper half part of the first blocking block 31V shape is blocked on the advancing route of the tubular piece 5 to be welded, and blocking and positioning of the tubular piece 5 to be welded are completed when the tubular piece 5 to be welded contacts the first blocking block 31. Then the second cylinder 42 pushes out the rotating motor 43 and the second blocking piece 41 toward the direction of the stand-by 12, after a certain distance, the second blocking piece 41 is positioned at the rear end of the tubular piece 5 to be welded, the rotating motor 43 starts to work, so that the second blocking piece 41 rotates inwards, then the second cylinder 42 contracts, so that the second blocking piece 41 is blocked at the rear end of the tubular piece 5 to be welded, and positioning of the rear end of the tubular piece 5 to be welded is completed.
At this point the adjustment module 6 starts to adjust the shape of the tubular piece 5 to be welded and the longitudinal slit 51. The adjusting cylinder 61 starts to operate to push the four pressing wheels 62 downward, so that the four pressing wheels 62 are uniformly pressed on the upper part of the cylindrical member 5 to be welded, and the cylindrical member 5 to be welded is contracted inwards. In addition, in the pressing process, the width between the longitudinal slits 51 can be controlled by adjusting the downward pushing distance of the pressing wheel 62, and if the width of the longitudinal slits 51 is larger, the pressing wheel 62 is pushed out downwards by the adjusting cylinder 61, so that the distance between the longitudinal slits 51 is narrowed; if the width of the longitudinal slits 51 is smaller, the adjusting cylinder 61 upwardly contracts the pressing wheel 62, so that the elastic deformation of the tubular member 5 to be welded widens the distance between the longitudinal slits 51, thereby achieving different welding requirements.
After the width and position of the longitudinal slit 51 are adjusted, the longitudinal slit 51 can be welded. After the welding is completed, the welded part is pushed out through the discharging module 8.
