Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 4 In the embodiment of the utility model, a workpiece flipping structure for an automatic spraying production line includes a workpiece fixing structure 1, the number of workpiece fixing structures 1 is several, the workpiece fixing structure 1 is slidably installed on the front side of the traveling structure 2, the rear side of the workpiece fixing structure 1 is slidably connected to the flipping structure 3, the flipping structure 3 includes a side plate 301, the bottom side of the side plate 301 is linearly and equidistantly arranged with a plurality of guide grooves 303, a hanger 302 is fixedly installed above the rear opening of the guide groove 303, a guide support piece 304 is fixedly installed at the lower end of the hanger 302, the upper end of the guide support piece 304 is inserted into the guide groove 303, a sliding column 306 is slidably abutted against the bottom side of the side plate 301, the number of the sliding columns 306 is several groups, and the number of each group is two, and each group of sliding columns 306 is rotatably installed at both ends of the connecting rod 305; the connecting rod 305 is fixedly installed on the rear side of the rear end 102.

[0023] Specifically, the side plate 301 is buried and installed in the side wall of the spraying tunnel, and the workpiece with holes and tubular shapes is fixed by the workpiece fixing structure 1, and then the moving structure 2 controls the workpiece fixing structure 1 as a whole and the connecting rod 305 to move synchronously, driving the workpiece to be sprayed through the spraying tunnel.
