[0035] refer to Figure 1-Figure 5 , an intelligent welding device for a pressure vessel, comprising:

[0036] A base 100, with a top plate 101 connected to the top of the base 100;

[0037] A first positioning plate 102 is disposed on the top of the base 100 , and a plurality of suction ports 103 are provided at the bottom of the first positioning plate 102 ;

[0038] The box body 104 is disposed at the bottom of the base 100 and is connected to the suction port 103. A movable plate 105 is disposed in the box body 104;

[0039] A ring body 106 is disposed on the top of the base 100, and a plurality of positioning rods 107 are disposed on the bottom of the ring body 106;

[0040] A first moving component is disposed between the base 100 and the top plate 101 and is used to move the top plate 101 up and down;

[0041] A fixing component, provided on the top plate 101, used for clamping and fixing the tank body of the pressure vessel;

[0042] The second moving component is disposed on the base 100 and is used to move the position of the ring body 106 downward. When the ring body 106 moves downward to a preset position, the position of the moving plate 105 can be moved downward. When the top plate 101 moves downward to a preset position, the position of the positioning rod 107 can be moved, and the positioning rod 107 is away from the end cover of the pressure vessel;

[0043] A welding component, provided on the ring body 106, used for welding the tank body and the end cover of the pressure vessel;

[0044] By setting the first positioning plate 102, when in use, the operator can place the end cover part of the pressure vessel that needs to be welded and connected in the first positioning plate 102, the outer wall of the end cover part can contact the inner wall of the first positioning plate 102, the welding surface of the end cover part faces the top plate 101, and the tank body part of the pressure vessel is set on the top plate 101, and the tank body is fixed by the set fixing component, and the welding surface of the tank body part of the pressure vessel faces the end cover. Specifically, the operator can use the second moving component to move the position of the ring body 106 downward, and the downward movement of the ring body 106 can drive the positioning rod 107 to move downward, and the positioning rod 107 can move to contact the end cover. The multiple positioning rods 107 that are set press the end cover to position the end cover, ensuring that the welding surface of the end cover is parallel to the base 100, which is convenient for subsequent welding work with the tank body. When the ring body 106 moves downward to the preset position, the position of the movable plate 105 can be displaced downward, and the movement of the movable plate 105 can generate negative pressure in the box body 104, and the end cover part can be subjected to the force of the negative pressure. The top plate 101 is then moved downwardly by the first moving component, and the top plate 101 moves the tank body of the pressure vessel downwardly through the fixing component. When the top plate 101 moves downwardly to a preset position, the positions of the multiple positioning rods 107 can be moved, and the positioning rods 107 leave the welding surface of the end cover part, and as the tank body moves downwardly to a preset position, the positioning rods 107 can contact the end cover, and the operator can open the welding component to weld the tank body and the end cover. The present application preliminarily positions the position of the end cover by multiple positioning rods 107, thereby ensuring that the welding surface of the end cover is parallel to the base 100 and the tank body, and fixes the position of the end cover by negative pressure through the movement of the moving plate 105. As the top plate 101 and the tank body move downwardly, the positioning rods 107 can leave the welding surface of the end cover, thereby ensuring the normal operation of the welding. Compared with the pressure vessel welding device in the prior art, the present application can solve the problem that the positioning of the end cover part of the pressure vessel is difficult, and the circular end cover part is easily displaced during welding, thereby affecting the welding quality.

[0045] As a further feature of the present invention, a slide groove 200 is provided at the top of the ring body 106, a slide rod 201 is slidably connected in the slide groove 200, a first spring 202 is connected between the slide rod 201 and the slide groove 200, a positioning rod 107 is slidably connected to one side of the slide rod 201, a second spring 203 is connected between the positioning rod 107 and the slide rod 201, a top contact block 204 is connected to the top of the slide rod 201, and a top rod 205 is connected to the bottom of the top plate 101;

[0046] By setting the positioning rod 107, when the ring body 106 moves downward, the positioning rod 107 can press the welding surface of the pressure vessel end cover through the sliding rod 201 and the second spring 203, and when the top plate 101 moves downward, it can drive the top rod 205 to move downward. When the top rod 205 moves to a preset position, it can contact the top contact block 204, and the top contact block 204 can be displaced by the force. The positioning rod 107 can be driven to move by the sliding rod 201, so that the positioning rod 107 can be moved away from the welding surface of the end cover part. When the end cover part is placed, the sliding rod 201 or the top contact block 204 can be moved to provide space for the end cover part to enter the first positioning plate 102.

[0047] As a further feature of the present invention, the second moving component includes a first electric push rod 300 connected to the base 100, the telescopic shaft of the first electric push rod 300 is connected to the ring body 106, the bottom of the moving plate 105 is connected to a connecting rod 301, the top of the connecting rod 301 passes through the base 100 and extends to the bottom of the ring body 106, there is a preset distance between the connecting rod 301 and the ring body 106, and a third spring 302 is connected between the connecting rod 301 and the base 100;

[0048] By setting the connecting rod 301, when the ring body 106 moves downward, it will first drive the positioning rod 107 to press the end cover part, so as to position the end cover part in advance. When the ring body 106 moves downward to the preset position, it will contact the push rod 205 and drive the push rod 205 to move the movable plate 105 downward. The end cover part is first positioned and then fixed. This avoids the problem that the welding surface of the end cover part cannot be parallel to the tank body after the end cover part is fixed. The first electric push rod 300 can support the position of the ring body 106. At the same time, the movement of the telescopic rod can achieve the purpose of moving the ring body 106 up and down. When the ring body 106 moves downward, the first electric push rod 300 can be stopped by making the center of the ring body 106 coincide with the center of the end cover part.

The operator can turn on the laser welding mechanism 402, and its welding head follows the movement of the rotating ring 400 and the ring body 106, and can correspond to the welding seam between the end cover and the tank body. As the rotating ring 400 rotates, the tank body and the end cover can be welded. After the rotating ring 400 rotates one circle, the rotating ring 400 can be reset to avoid the problem of entanglement of the cables used to connect the laser welding mechanism 402.

[0051] As a further feature of the present invention, the fixing component includes a fixing port 500 opened at the top of the top plate 101, a plurality of connecting grooves 501 are opened at the top of the top plate 101, a second electric push rod 502 is connected in the connecting groove 501, a clamping block 503 is connected to the telescopic shaft of the second electric push rod 502, and a second positioning plate 504 is connected to the top of the top plate 101;
