[0002] Switchgear is an electrical equipment, whose main function is to open, close, control and protect electrical equipment in the process of power generation, transmission, distribution and power conversion in the power system. The components in the switchgear mainly include circuit breakers, disconnectors, load switches, operating mechanisms, transformers and various protection devices. According to the different cabinet structures, switchgear can be divided into open switchgear, metal-enclosed switchgear, and metal-enclosed armored switchgear. The production of switchgear first designs the product according to customer needs and requirements, and performs relevant calculations and analyses. At the same time, process planning is required, and the metal plates are cut and punched according to the installation design requirements to obtain metal plates and components of various sizes.

Since the side wall of the drive mounting platform 524 is recessed with a threaded hole 525, the threaded hole 525 is set on the screw rod 515, and the lateral positioning mounting frame is driven. 521 moves along the third slide rail 513 toward the welding workbench 22 until the lateral clamping plate 43 moves above the welding workbench 22, and then the back plate of the switch cabinet to be welded is placed on the top surface of the bottom plate of the switch cabinet to be welded, and the two ends of the back plate are respectively attached to the inner sides of the two side plates, and then, one of the positioning adjustment cylinders 526 is respectively started, so that the output shaft of the positioning adjustment cylinder 526 extends, and the mounting rotating rod 522 on the directional clamping plate 523 is pushed to rotate outward around the two rotating pin seats 527 until the outer side of the directional clamping plate 523 is abutted against the inner side of the first inclined back plate, and then the other positioning adjustment cylinder 526 is started. 26 and repeat the above-mentioned action process, so that the outer side of another directional clamping plate 523 is pressed against the inner side of the second inclined back plate, and then the plurality of third electromagnets 541 are synchronously started, so that the back plate of the switch cabinet to be welded is clamped on the inner side of the positioning assembly 50, and then the driving motor is reversely started, so that the two lateral positioning mounting frames 521 are synchronously moved along the third slide rail 513 away from one end of the welding workbench 22, so that the back plate follows the movement until the outer side of the back plate and the inner side of the bottom plate are located on the same horizontal plane, and then the welding robot arm is started to weld, and the welding sequence is from the connection between the bottom plate and the back plate to the connection between the two side walls and the back plate.

[0049] For example, in one embodiment: when the welding robot arm welds the connection between the bottom plate and the back plate, the hot air blower 51 will be started to blow a uniform temperature airflow containing a relatively high content of inert gas from the two air outlets 511. When the uniform temperature airflow blows toward the air guide rack 32, the air guide rack 32 will generate a force acting on the switch cabinet to be welded, and because the elastic triangular portion 324 is made of elastic material, the top of the elastic triangular portion 324 will be bent by the impact of the uniform temperature airflow, so that the outer side of the elastic triangular portion 324 is pressed against the inner side of the bottom plate, generating a covering force on the connection between the bottom plate and the back plate. At the same time, when the uniform temperature airflow impacts the air guide rack 32, the air guide rack 32 will generate an upward rotational restoring force around the mounting bar 31, which will generate a slight upward stress on the inner side of the bottom plate and a slight inward stress on the bottom of the back plate. Since the bottom of the mounting rotating portion 311 is fixedly installed in the first rotating groove In 221, the elastic sliding part 312 is made of elastic material, the inner ends of the two elastic sliding parts 312 are fixedly installed at the two ends of the mounting rotating part 311 respectively, and the bottoms of the two elastic sliding parts 312 are slidably installed in the two arc-shaped slide grooves 222 respectively. When the uniform temperature airflow blows to the air guide rack 32, the elastic sliding part 312 located in the two arc-shaped slide grooves 222 will slide along the arc-shaped slide grooves 222 under the impact of the uniform temperature airflow until the outer sides of the multiple air guide triangle blocks 323 on the elastic sliding part 312 are abutted against the inner side of the bottom plate, and the above-mentioned uniform stress is provided to the inner side of the bottom plate and the bottom of the back plate, so that the stress can be evenly distributed at the connection between the bottom plate and the back plate, so as to ensure that the connection between the bottom plate and the back plate is tight, and to prevent the occurrence of plate deformation, twisting or warping when the electromagnet is used for fixing. At the same time, welding stress is applied to reduce deformation stress and ensure the uniformity of the weld.

[0050] When the uniform temperature airflow blows toward the air guide rack 32, part of the uniform temperature airflow will rush directly from between the multiple air guide triangle blocks 323 to the connection between the bottom plate and the back plate, providing uniform temperature for the welding at the connection between the bottom plate and the back plate, thereby more accurately controlling the heat input of the welding part and providing an inert gas welding protection environment at the connection between the bottom plate and the back plate, effectively reducing the intrusion of oxygen and impurities, helping to reduce heat input, and reducing deformation stress. At the same time, another part of the uniform temperature airflow will move upward under the guidance of the air guide surface 327 and be sent to the arc plate 529. Since the arc plate 529 is tilted downward and the directional clamping plate 523 is tilted at this time, this part of the uniform temperature airflow will gather on the inner side of the arc plate 529 and the directional clamping plate 523. Since this part of the uniform temperature airflow flows out from the welding part, it absorbs a large amount of heat from the welding part. This heat will provide preheating for the subsequent welding part of the connection between the bottom plate and the back plate, so as to reduce the thermal stress during welding, reduce deformation during welding, and ensure welding quality. At the same time, this portion of the uniform temperature airflow will flow along the air gathering plate 520 to the air gathering and heating space 53 to synchronously preheat the subsequent connection between the two side walls and the back plate.
