[0036] Working principle: During the use of this device, it is necessary to synchronously drive the flipping device 2 and the clamping device 3 below to approach the material through the set Y-axis motion frame 4, X-axis motion frame 5 and Z-axis motion frame 7 while the machine tool is processing the workpiece, and start the motor 303 to start rotation. At this time, the motor 303 will drive the outer fixed block 306 to rotate. At this time, the fixed block 306 will reach the material position.

At the same time, in order to avoid motion interference between the internal components of the machine tool and the device, it is necessary to control the cylinder 204 to move accordingly. When the cylinder 204 is extended or retracted, the rotating shaft 207 will be driven to rotate through the hinge block 206. At this time, the clamping device 3 under the rotating shaft 207 will be driven to flip accordingly, thereby avoiding the processing station of the machine tool. When loading is required, only reverse air supply is required to drive the cylinder 204 to move in the opposite direction and drive the clamping device 3 to flip to the loading station.
