[0020] The two second electric push rods 9 can drive the protection block 12 to move, so that the protection block 12 moves along the inner wall of the groove.

When the protection block 12 moves downward along the inner wall of the groove, it drives the slider 20 and the mounting block 10 to move. The slider 20 moves along the slide groove and is limited by the limiting block 21 to move along the limiting groove to prevent the slider 20 from moving out of the slide groove. The slider 20 facilitates the connection between the protection block 12 and the mounting block 10, so that when the nozzle 16 inside the mounting block 10 is sprayed for repair, the welding head 6 can be protected under the action of the protection block 12, thereby increasing the service life of the welding head 6 and facilitating use.

[0021] like Figure 8 As shown, a welding repair agent is provided inside the storage box 17, a control valve is provided at one end of the delivery pipe 18, the nozzle 16 is made of elastic telescopic material, an electric telescopic plate 22 is fixedly installed on one side of the nozzle 16 and at the bottom of one end of the moving block 15, a moving brush 23 is fixedly installed at the bottom of the electric telescopic plate 22, and an adjustment structure 24 is provided on the outside of the nozzle 16 and at the bottom of the moving block 15.

The nozzle 16 sprays the welding repair agent to the part where the repair is needed. Then, the electric telescopic plate 22 is started to drive the moving brush 23 to move to the part where the repair is needed. When the moving structure 3 drives the fixed block 5 and the mounting block 10 to move, the moving brush 23 spreads the sprayed welding repair agent evenly, thereby facilitating the improvement of the repair effect. The nozzle 16 can be deflected by the adjustment structure 24, so that the nozzle 16 can be deflected to different angles, and the pores and cracks at different angles and positions can be repaired, thereby improving the comprehensiveness of the repair.

[0023] like Figure 4 , Figure 7 As shown, the movable structure includes a first motor 25, the output end of the first motor 25 is transmission-connected with a threaded rod 26, one end of the threaded rod 26 is threadedly connected with a movable plate 27, one side of the movable plate 27 is slidably connected to the inner wall of the first mounting groove, both sides of the movable plate 27 are hinged with rotating plates 28, one end of the rotating plate 28 is hinged with a second baffle 29, a first rack 30 is fixedly installed on the side of the second baffle 29 away from the first motor 25, the first rack 30 is meshed with a gear 31, a rotating rod is fixedly installed in the middle of the gear 31, a second rack 32 is meshed with one side of the gear 31, and the second rack 32 is fixedly installed with the first baffle 19.

[0024] By starting the first motor 25 to drive the threaded rod 26 to rotate, the movable plate 27 moves away from the first motor 25, thereby deflecting the rotating plate 28, so that the second baffle 29 moves away from each other, and when the second baffle 29 moves, it drives the first rack 30 to move, so that the gear 31 drives the rotating rod to rotate, and the second rack 32 drives the first baffle 19 to move closer to each other, so as to facilitate the first movable opening at the bottom of the mounting block 10 to be exposed for repairing parts, and at the same time, the first baffle 19 is moved to the bottom of the protective block 12 to shield and protect the bottom of the protective block 12, thereby increasing the service life of the welding head 6 and preventing damage that affects the welding effect.

When the first motor 25 rotates with the threaded rod 26, the threaded rod 26 rotates along the inner wall of the first mounting groove, so that the movable plate 27 moves along the inner wall of the first mounting groove, and the rotating plate 28 is deflected to drive the first baffles 19 away from each other and no longer fit together, so that the nozzle 16 can move out of the mounting block 10 through the first movable opening, so that the nozzle 16 can be sprayed and repaired, which is convenient for use.

[0027] like Figures 4 to 7 As shown, a second movable opening is opened on one side of the movable block 15, the first rack 30, the second rack 32 and the gear 31 are all located inside the second movable opening, the first rack 30 and the second rack 32 are both slidably connected to the inner wall of the second movable opening, the upper and lower sides of the rotating rod are rotatably connected to the inner wall of the second movable opening, the first baffle 19 is located inside the second mounting groove, and its bottom is slidably connected to the inner wall of the second mounting groove.

[0028] The second movable opening is used to facilitate the installation of the first rack 30, the second rack 32 and the gear 31. When the second baffle 29 moves away from each other, it drives the first rack 30 to move, so that the gear 31 drives the rotating rod to move along the inner wall of the second movable opening, and the first baffle 19 brought by the second rack 32 moves closer to each other, which can shield and protect the bottom of the protective block 12 that moves out of the groove, thereby further facilitating the improvement of the protective effect of the protective block 12 on the welding head 6.

[0030] The third electric push rod 242 is installed through the connecting plate 241, and the third electric push rod 242 is started to drive the pushing plate 243 to move along the bottom of the moving plate 27, so that the pushing plate 243 pushes the movable block 244 to move toward the adjusting block 246, and the movable block 244 moves along the bottom of the moving block 15 to squeeze the connecting spring 245. Under the action of the connecting spring 245, the adjusting block 246 drives the nozzle 16 to deflect. Through the action of the connecting spring 245, the movable block 244 is no longer squeezed by the pushing plate 243, and the adjusting block 246 and the nozzle 16 are driven to move to the original position, so that the nozzle 16 is convenient to deflect again. Through the connecting plate 241, the third electric push rod 242, the pushing plate 243, the movable block 244 and the connecting spring 245 distributed in a circular array, the nozzle 16 can repair the pores and cracks at different angles and positions, thereby improving the repair effect.

[0032] When the welding repair agent is sprayed and evenly applied, the nozzle 16 moves to the inside of the mounting block 10, and the second motor 33 is started to drive the movable rod 34 to rotate along the second mounting plate, so that the movable plate 35 moves along the bottom of the mounting block 10 and the movable rod 34, so that the movable block 244 drives the two fans 36 to move, so that the fans 36 dry the welded repaired parts, further improving the repair effect, thereby facilitating the continued welding of parts and improving the welding effect.

[0033] Working principle: by fixing the parts on the workbench 1, the mobile structure 3 drives the first connecting block 4, the mounting block 10 and the fixed block 5 to move to the top of the parts through the display screen, so that the welding head 6 is aligned with the part that needs to be welded, and the first electric push rod 7 drives the fixed block 5, the mounting block 10 and the welding head 6 to move to the place where the parts need to be welded, and welding is performed through the welding head 6. When pores and cracks are generated during welding, the second electric push rod 9 is started to drive the protective block 12 to move downward along the inner wall of the groove. When the protective block 12 moves downward, it drives the second connecting block 13, the slider 20 and the mounting block 10 to move downward. The slider 20 moves along the slide groove, and the limiting block 21 moves along the limiting groove to limit the slider 20 to prevent the slider 20 from moving out of the slide groove, so that the protective block 12 moves out of the groove to the outside of the welding head 6 to protect the welding head 6, and then the first motor 25 is started to drive the threaded rod 26 to rotate. The movable plate 27 moves away from the first motor 25, thereby deflecting the rotating plate 28, so that the second baffles 29 move away from each other to expose the first movable opening, and when the second baffle 29 moves, it drives the first rack 30 to move, so that the gear 31 drives the rotating rod to rotate along the inner wall of the second movable opening, and the second rack 32 drives the first baffle 19 to move closer to each other, so as to facilitate the exposure of the first movable opening at the bottom of the mounting block 10, and at the same time, the first baffle 19 moves to the bottom of the protective block 12, and the bottom of the protective block 12 is blocked, so as to facilitate the protection of the welding head 6, and then the electric telescopic rod 14 is started to drive the movable block 15 and the nozzle 16 to move downward, so that the nozzle 16 moves to the top of the mounting block 10, and then the nozzle 16 is aligned with the part to be repaired through the movable structure 3, and the welding repair agent inside the storage box 17 is sprayed by the nozzle 16 through the delivery pipe 18, so that the pores and cracks generated during the welding of parts are repaired.

[0034] When the nozzle 16 moves to the repaired part, the electric telescopic plate 22 is started at the same time to drive the moving brush 23 to move to the part where the part needs to be repaired. When the moving structure 3 drives the fixed block 5 and the mounting block 10 to move, the nozzle 16 sprays the welding repair agent, and the moving brush 23 spreads the sprayed welding repair agent evenly, so as to improve the repair effect. When repairs are required at different angles and different parts, the third electric push rod 242 is started to drive the push plate 243 to move along the bottom of the moving plate 27, so that the push plate 243 pushes the movable block 244 to move toward the adjustment block 246, and the movable block 244 moves along The bottom of the movable block 15 moves and squeezes the connecting spring 245. Under the action of the connecting spring 245, the adjusting block 246 drives the nozzle 16 to deflect, so as to repair the pores and cracks at different angles and positions. After the spraying is completed, the movable block 15 and the nozzle 16 are driven to move to the inside of the fixed block 5 by the electric telescopic rod 14, and the movable rod 34 is driven to rotate along the second mounting plate by starting the second motor 33, so that the movable plate 35 moves along the bottom of the mounting block 10 and the movable rod 34, so that the movable block 244 drives the two fans 36 to move, so that the fans 36 can blow dry the welded repaired parts.

[0035] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
