Description

Technical Field

[0001] The utility model relates to the field of automobile production, in particular to a vehicle frame turning mechanism for an automobile production line. Background Art

[0002] The vehicle frame flipping mechanism is a device used to flip the car body frame. It is usually composed of a clamp and a supporting structure, and can flip the body frame from one direction to another. This mechanism is mainly used in assembly, welding, spraying and inspection processes on automobile production lines.

[0003] The patent with publication number CN112808541A ​​is specifically a flipping mechanism for coating of automobile frame. By arranging the cross bar, the fixing plate, the rotating plate, the handle, the first clamping block, the second clamping block and the electric push rod, the present invention can fix the automobile frame leftward and rightward and up and down, so that when the automobile frame is subsequently flipped, the flipping mechanism of the existing automobile frame not only clamps the automobile frame leftward but also clamps the automobile frame leftward and rightward in order to prevent the automobile frame from shaking when clamping the automobile frame. During the clamping process of the automobile frame, because it is to be flipped, the upper and lower limits of the automobile frame by the existing flipping mechanism are limited by the baffle plate fixedly connected to the upper end of the clamping plate. Because the existing left and right clamping method of the automobile frame uses the weight of the automobile frame to push the push rod, the left and right clamping plates are driven to move toward the middle. When the inner side of the baffle plate fixedly connected to the upper end of the clamping plate is attached to the outer side of the automobile frame, the automobile frame will not be able to move up and down after the processing is completed, and the limit of the clamping plate cannot be cancelled. Therefore, the existing baffle plate fixedly connected to the upper end of the clamping plate and the automobile frame will move with a certain gap, which makes the automobile frame unstable when flipping.
