The driving motor 206 drives the rotating block 205 to rotate, and then drives the flipping piece 3 to rotate, so as to flip the robot welding object. A mounting plate 207 is provided at the bottom of the driving motor 206, and a reinforcement block 208 is provided at the bottom of the mounting plate 207. The mounting plate 207 is used to install the driving motor 206. The reinforcement block 208 is used to ensure that the driving motor 206 and the fixed base plate 201 are firmly fixed to ensure the stable use of the device.

The two groups of first cylinders 202 are respectively provided at both ends of the welding machine table 1, and are used to lift the flipping piece 3 to ensure that the welding object can be flipped.

[0025] The flip member 3 includes a fixed frame 301, a mounting frame 302, a second cylinder 303, a moving rod 304 and a push plate 305.
