A lifting and adjusting component is located below the moving end of the horizontal moving component. A mounting frame 5 is located at the lower end of the lifting and adjusting component. A flipping control component is located inside the mounting frame 5. A rotating table 6 is located at the drive end of the flipping control component. A mechanical gripper 7 is mounted on the rotating table 6. The valve body conveyor 3 transports the ball valve body with the valve ball and valve stem already installed. The valve cover conveyor 4 transports the ball valve cover with the sealing ring already installed. When the valve cover moves to below the stand 1, it is gripped by the mechanical gripper... Claw 7 clamps and fixes the valve cover. After clamping and fixing, the lifting and adjusting component is activated to move the rotating table 6 and the valve cover upwards synchronously to a certain height. Then, the horizontal moving component is controlled to move the valve cover to a position above the valve body conveyor 3. During the horizontal movement, the flipping control component is activated to drive the rotating table 6 and the valve cover to flip 180° synchronously. After the flipping is completed, the valve body conveyor 3 moves the valve body to below the valve cover and controls the valve cover to move downwards to fasten the valve cover onto the valve body. The mechanical clamp 7 is released, and the fastened valve body moves to the locking position under the drive of the valve body conveyor 3. The structure is compact and the operation is convenient. The entire flipping and fastening operation can be automated, which can greatly improve the overall efficiency of ball valve assembly.

An arc-shaped slider 12 is slidably mounted on the annular guide rail 11. An installation plate 13 is welded to one side of the arc-shaped slider 12. The installation plate 13 is assembled and connected to the rotating table 6. After the mechanical gripper 7 clamps and fixes the valve cover, the mounting frame 5 and the valve cover are simultaneously lifted to a certain height by the lifting adjustment component. Then, the servo motor 8 in the mounting frame 5 is started. Through the cooperation of the servo motor 8 and the reducer 9, the directional and angle rotation control of the fixed shaft 10 is realized, thereby driving the installation plate 13 and the rotating table 6 to rotate synchronously by 180°, thereby realizing the flipping control of the valve cover.

In use, the screw module 18 is used as the power to adjust the position of the mounting frame 5 in the vertical direction, thereby realizing the adjustment of the position of the grasped valve cover in the vertical height, thus providing sufficient space for the flipping operation. In addition, the cooperation between the guide columns 20 and the guide blocks 21 can further improve the smoothness and reliability of the movement of the mounting frame 5.

[0021] In the specific implementation process, the valve body conveyor 3 is provided with a fixed interval along the upper edge of a mobile carrier 22 for placing the valve body, and the valve cover conveyor 4 is provided with a fixed interval along the upper edge of a mobile carrier 22 for placing the valve cover.
