Through the above operation, it is convenient to automatically flip the automobile sheet metal parts, thereby improving its flexibility;

[0028] An adjustment plate 11 is installed on one side of the flip shaft 7 and the rotating mechanism 3, and a connecting frame 5 is installed on both sides of the adjustment plate 11. The interior of the connecting frame 5 is evenly penetrated by threaded rods 9, and a clamping block 10 is installed on one side of the threaded rods 9;

[0036] Working principle: When the utility model is used, first, when it is necessary to weld the automobile sheet metal parts, the automobile sheet metal parts are placed between the two connecting frames 5, and the clamping block 10 is driven to move downward or upward by screwing the threaded rod 9 until the clamping block 10 and the automobile sheet metal parts are fitted together, thereby limiting the position of the automobile sheet metal parts, and then it is convenient for the staff to perform welding operations on the clamped automobile sheet metal parts;

The driven bevel gear 603 rotates and drives the adjusting shaft 604 to rotate synchronously, thereby driving a group of movable blocks 605 to perform opposite lifting movements. The movable blocks 605 perform opposite lifting movements and push a group of connecting frames 5 to perform synchronous opposite lifting movements. The above operation makes it easy for a single person to adjust the distance between the two connecting frames 5 according to actual usage conditions, thereby facilitating the limit clamping of automobile sheet metal parts of different sizes, thereby improving the welding efficiency.
