Obviously, the described embodiments are 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.

[0024] The embodiment of the present invention provides a plasma arc welding machine for high-performance material circular mechanical parts. It includes a welding box assembly 1, exemplarily, such as Figure 1 As shown, a protection component 2 is installed on one inner wall of the welding box component 1, a processing component 4 is installed on the welding box component 1, and a welding component 3 is installed on the bottom.

[0027] During the high-temperature welding process, the dry ice block 413 will be driven to vaporize quickly to absorb heat, thereby avoiding damage to the structure due to high temperature and increasing the service life of the equipment.

After the second compression spring 402 senses the disappearance of pressure, it begins to drive the second connecting plate 403 to move away from the first connecting plate 401. During the movement, the sliding baffle 411 is driven to move to the bottom of the plasma arc welding structure 306. During the movement of the fan steel plate, the fan steel plate on the clamping structure 208 drives the sliding plate 206 to slide in the slide groove 204 to squeeze the first compression spring 207 for buffering protection, thereby improving the adjustability of the welding position and the working effect of the plasma arc welding machine.

As the welding point moves, the seventh electric push rod 414 can be started for auxiliary adjustment. In subsequent heat dissipation work, the first electric push rod 103 can be started to push the insulation board 104 to move for heat dissipation. In order to improve the maintenance effect of the structure, the second electric push rod 108 is started to drive the top plate 109 to rise, thereby improving the convenience of device maintenance.

[0032] After the two groups of clamping blocks 410 clamp the fan steel plate in place, the fourth electric push rod 404 is started to push the first electromagnetic block 405 and the second electromagnetic block 406 to be magnetically connected, and then the fourth electric push rod 404 drives the second connecting plate 403 to move toward the direction close to the first connecting plate 401, and the plasma arc welding structure is started for welding. In order to increase the welding range, the second electric slide 301 is started to drive the plasma arc welding structure 306 to perform translational welding. Subsequently, in order to improve the protection effect of plasma arc welding, the third electric push rod 304 can be started to push the protective fan ring 305 to the designated position to block and protect against high temperature. After the subsequent work is completed, the two groups of protective fan rings can be started to align for wrapping protection, thereby improving the protection effect of the device.

[0033] During high-temperature welding, the dry ice block 413 is driven to vaporize quickly to absorb heat, thereby avoiding damage to the structure caused by high temperature and increasing the service life of the equipment. When a fault or deviation occurs during welding, the second compression spring 402 senses that the pressure disappears and drives the sliding baffle 411 to move to the bottom of the plasma arc welding structure 306. During the movement of the fan steel plate, the fan steel plate on the clamping structure 208 drives the sliding plate 206 to slide in the slide groove 204 and squeeze the first compression spring 207 for buffering protection, thereby improving the adjustability of the welding position and improving the working effect of the plasma arc welding machine.

[0034] When welding, the auxiliary disc 416 is located below the welding point, which provides auxiliary support and stability for the fan steel plate. As the welding point moves, the seventh electric push rod 414 can be started for auxiliary adjustment. In subsequent heat dissipation work, the first electric push rod 103 can be started to push the insulation board 104 to move for heat dissipation. In order to improve the maintenance effect of the structure, the second electric push rod 108 is started to drive the top plate 109 to rise, thereby improving the convenience of device maintenance.

[0035] Before the plasma arc welding machine starts working, one group of fan steel plates that need to be welded is first placed on the clamping structure 208 for limit clamping, and then the first electric slide 201 is started for height adjustment, and then the other group of fan steel plates is placed between the two groups of clamping blocks 410, and then the fifth electric push rod 407 is started to push the fourth fixed block 408 to move toward each other, so that the two groups of clamping blocks 410 clamp and limit the fan steel plates, and then the sixth electric push rod 409 is started for height adjustment, which improves the steel plate alignment effect while improving the device clamping compatibility effect.

[0036] After the two groups of clamping blocks 410 clamp the fan steel plate in place, the fourth electric push rod 404 is started to push the first electromagnetic block 405 and the second electromagnetic block 406 to be magnetically connected, and then the fourth electric push rod 404 drives the second connecting plate 403 to move toward the direction close to the first connecting plate 401, and the plasma arc welding structure is started for welding. In order to increase the welding range, the second electric slide 301 is started to drive the plasma arc welding structure 306 to perform translational welding. Subsequently, in order to improve the protection effect of plasma arc welding, the third electric push rod 304 can be started to push the protective fan ring 305 to the designated position to block and protect against high temperature. After the subsequent work is completed, the two groups of protective fan rings can be started to align for wrapping protection, thereby improving the protection effect of the device.
