The inside of the sealing rotary disc 43 and the rotating rod 41 are both provided with a through hole 431. The inside of the rotating rod 41 is connected to the inside of the rotating groove 42 through the through hole 431. The end face of the rotating rod 41 is fixedly connected to the placement rack 44. The placement rack 44 It is in the shape of an "L". A pressure plate 45 is rotatably connected to the interior of the placement frame 44. A gear 46 is fixedly connected to the surface of the pressure plate 45. A cylinder 47 is fixedly installed inside the placement frame 44. The interior of the cylinder 47 is connected to the interior of the rotating rod 41. The output end of the cylinder 47 is fixedly connected to a connecting block 48.

[0024] The interior of the pressurizing chamber 5 is connected to the interior of the rotating groove 42 through the air outlet pipe 51, the solenoid valve 52 and the connecting pipe 410. By providing a rotatable pressure plate 45, after the automobile frame is placed on the surface of the placement rack 44, the second electric telescopic rod 6 is activated to pressurize the interior of the cylinder 47, and the engagement of the tooth plate 49 with the gear 46 drives the pressure plate 45 to rotate, which can automatically and quickly clamp and position the automobile frame placed on the surface of the placement rack 44.

[0025] A sealed chamber 411 is provided inside the base 1, and a piston rod 412 is sealingly and slidingly connected to the inside of the sealed chamber 411.

[0026] During operation, the car frame is placed on the surface of the placement rack 44, and then the sealing plate 61 is driven to slide by starting the second electric telescopic rod 6. At this time, the inside of the boost chamber 5 is in a strong pressure state. The strong pressure inside the boost chamber 5 enters the inside of the rotating groove 42 through the air outlet pipe 51, the solenoid valve 52 and the connecting pipe 410, and then enters the inside of the rotating rod 41 and the cylinder 47 through the through hole 431.

At this time, the inside of the boost chamber 5 is in a negative pressure state. Due to the closure of the solenoid valve 52, only the inside of the sealing chamber 411 is connected to the inside of the boost chamber 5. Due to the negative pressure inside the boost chamber 5, the piston rod 412 drives the gear block 413 to slide in the direction away from the gear ring 414. When the gear block 413 is not engaged with the gear ring 414, the rotating rod 41 can be rotated freely. After turning the car frame over, the sealing disk 61 is driven to slide again in the direction close to the solenoid valve 52 by starting the second electric telescopic rod 6. At this time, the inside of the sealing chamber 411 is in a strong pressure state again, and the surface of the gear block 413 is engaged and connected to the surface of the gear ring 414, which can position the rotation angle of the rotating rod 41, ensuring stability during welding after the car frame is turned over.
