Place the steel structure grid component to be welded between two sets of limit blocks, start the electric push rod of the positioning mechanism, and the electric push rod pushes the power block to slide inside the fixed frame. The power block slides on the support frame through the slider to ensure the stability of movement.

[0018] S2. When the clamping block contacts the steel structure grid component, under the action of the tension spring in the reset assembly, the two clamping blocks rotate around the connection point with the power block, gradually clamping the component, and the arc-shaped limit block at one end of the clamping block fits tightly with the component to ensure firm fixation;

The transition box then transports the dust and impurities to the storage box for storage.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The present invention facilitates the welding of some specific structures of steel structure grid frames for building construction through the design of the positioning mechanism, and can clamp and fix U-shaped or N-shaped steel structure grid frames for building construction. Due to the effective fixation, the components are not easy to move or shake during the welding process. The electric push rod of the positioning mechanism is started, and the electric push rod pushes the power block to slide inside the fixing frame, and the power block slides on the supporting frame through the slider. As the power block moves, the power block drives the clamping blocks at both ends to approach the steel structure grid frame component. When the clamping block contacts the steel structure grid frame component, under the action of the tension spring in the reset assembly, the two clamping blocks rotate around the connection point with the power block, gradually clamping the component, and the arc-shaped limit block at one end of the clamping block is tightly fitted with the component to ensure firm fixation. This clamping method can adapt to components of different shapes and sizes, ensure that the clamping block is tightly fitted with the component, and achieve firm fixation. Through the precise control of the electric push rod, the position of the clamping block can be adjusted according to different welding requirements, thereby improving the versatility and adaptability of the device.

[0023] The present invention facilitates the adjustment of the angle of the welding rod through the design of the welding mechanism, thereby facilitating the welding of steel structure grid components of the building from different angles. The hydraulic rod of the welding mechanism is started, and the hydraulic rod drives the fixed frame to move downward, so that the welding rod is close to the welding position of the steel structure grid. The driving motor is started, and the driving motor drives the worm to rotate. The worm engages with the turbine, thereby driving the rotating shaft to rotate, and then the welding rod rotates in the fixed frame. The welding rod performs welding operations on the steel structure grid. The worm is driven by the driving motor to rotate, and then the welding rod rotates in the fixed frame, so that uniform welding of the welding position can be achieved. This uniform welding can improve the strength and sealing of the weld, reduce welding stress concentration, and enhance the overall performance and reliability of the steel structure grid.

[0024] The present invention can process the waste slag generated by welding through the design of the cleaning mechanism, and provide a good working environment for welders. During the welding process, the dust suction component of the cleaning mechanism is started, and the vacuum cleaner sucks in the dust and impurities generated by welding through the dust suction plate, and transports them to the transition box through the duct, and the transition box then transports the dust and impurities to the storage box for storage. A large amount of dust and impurities will be generated during the welding process. These substances will not only affect the cleanliness of the working environment, but may also cause harm to the health of welders. The cleaning mechanism can suck in and store these dust and impurities in time, effectively reducing the content of pollutants in the air, and providing a cleaner and more comfortable working environment for welders.
