[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The present invention provides three technical solutions, including the following embodiments:

[0032] Example 1

[0033] See also Figure 1-Figure 3 A welding device for processing pressure vessels, comprising a welding seat 1, the welding seat 1 is a stable and durable supporting platform for the entire device, a disc 2 is rotatably connected to the top of the welding seat 1, a pressure cylinder 3 is placed in the disc 2, the pressure cylinder 3 is a pressure vessel, and is placed in the disc 2, and an automatic rotating welding slag cleaning mechanism 4 is provided on the welding seat 1 to drive the pressure cylinder 3 to rotate and clean the welding slag on the cylinder body;

[0034] The automatic rotating welding slag cleaning mechanism 4 includes a rotating column 41 fixed to the bottom of the disc 2, the bottom end of the rotating column 41 extends to the inside of the welding seat 1, the bottom end of the rotating column 41 is rotatably connected to the bottom wall of the welding seat 1, one side of the welding seat 1 is rotatably connected to a rotating rod 42, one end of the rotating rod 42 extends to the inside of the welding seat 1, one end of the rotating rod 42 is fixed to a bevel gear 1 43, a bevel gear 2 44 is fixed on the rotating column 41, the bevel gear 1 43 is meshed with the bevel gear 2 44, a horizontal plate 45 is fixed to one side of the welding seat 1, and the horizontal plate 4 A motor 46 is fixed on the top of 5, and the motor 46 is controlled by an external switch and electrically connected to an external power supply. The motor 46 drives the rotating rod 42 to rotate. A scraper 47 is arranged on one side of the pressure cylinder 3. The scraper 47 is made of high-hardness, wear-resistant material to ensure that the cylinder body will not be damaged while scraping off the welding slag. One side of the scraper 47 contacts one side of the pressure cylinder 3. When the pressure cylinder 3 rotates, the scraper 47 scrapes off the welding slag on the cylinder body of the pressure cylinder 3, ensuring that the welding surface is smooth and flawless, laying a solid foundation for subsequent welding procedures.

[0035] Example 2

[0036] Based on Example 1, see Figure 3-Figure 4 As shown, the welding seat 1 is provided with a reciprocating cleaning assembly 48 that drives the scraper 47 to move up and down reciprocatingly. The reciprocating cleaning assembly 48 includes a rod seat 481 fixed on one side of the top of the welding seat 1, and a transmission rod 482 is rotatably connected to the rod seat 481. The transmission rod 482 is synchronously rotated with the rotating rod 42 through a pulley 483. This transmission method is not only simple in structure and reliable, but also can ensure that the rotation speeds of the two are consistent. Pulleys 483 are fixed on the rotating rod 42 and one end of the transmission rod 482. The two pulleys 483 are connected by a belt 484. A vertical plate 485 is fixed on the top of the welding seat 1. The setting of the pulley 483 and the belt 484 can drive the transmission rod 482 and the rotating rod 42 to rotate synchronously.

[0037] A U-shaped frame 486 is fixed to the top of the vertical plate 485, and a rotating wheel 487 is rotatably connected inside the U-shaped frame 486. A wave groove 488 is opened on the rotating wheel 487. Due to the arrangement of the wave groove 488, when the rotating wheel 487 rotates, the connecting column 4810 slides back and forth up and down along the inner surface of the wave groove 488. A sliding rod 489 is slidably connected to the U-shaped frame 486. A connecting column 4810 is fixed to one side of the sliding rod 489. One end of the connecting column 4810 extends to the inside of the wave groove 488. The outer surface of the connecting column 4810 is slidably connected to the inner surface of the wave groove 488. As the transmission rod 482 rotates, the bevel gear four 4814 fixed thereon drives the bevel gear three 4813 and the rotating wheel 487 to rotate synchronously. The wave groove 488 on the rotating wheel 487 serves as a key motion conversion element, converting the rotational motion into the up and down reciprocating sliding of the sliding rod 489.

[0038] A connecting rod 4811 is fixed to one side of the sliding rod 489, one end of the connecting rod 4811 is fixed to one side of the scraper 47, a vertical rod 4812 is fixed to the bottom of the rotating wheel 487, the bottom end of the vertical rod 4812 passes through the U-shaped frame 486 and extends to the bottom of the U-shaped frame 486, a bevel gear three 4813 is fixed to the bottom end of the vertical rod 4812, a bevel gear four 4814 is fixed to one end of the transmission rod 482, and the bevel gear three 4813 is meshed with the bevel gear four 4814.

[0039] By setting up the automatic rotating welding slag cleaning mechanism 4, it is possible to drive the pressure cylinder 3 to rotate, and cooperate with the lifting welding unit 7 to perform all-round welding processing on the pressure cylinder 3. There is no need to manually adjust the position of the pressure cylinder 3 or the welding pen 75. Through the up and down reciprocating movement of the scraper 47, combined with the rotation of the pressure cylinder 3, the welding slag can be automatically and quickly removed when it is just formed, which solves the problem that the welding slag is difficult to remove cleanly after it is completely cooled.

[0042] By setting the cooling component 5, the cooling component 5 is installed on one side of the scraper 47. As the scraper 47 moves up and down, the fan 51 is started to blow out wind to quickly and evenly cool the body of the pressure cylinder 3, thereby increasing the cooling speed after welding and improving the processing efficiency.

The bottom end of the L-shaped tube 65 is connected to a horizontal tube 66. The bottom end of the horizontal tube 66 is connected to multiple suction heads 67. Multiple suction heads 67 are provided to quickly absorb welding slag.

[0045] By setting the welding slag suction component 6, the scraped welding slag is uniformly collected and gathered, and then sucked into the collection box 61 by the suction pump 64 and the suction head 67 for collection and storage, so as to avoid the welding slag from polluting the working environment.
