The tail lug is connected to the second pin of the first four-way pin 510.

[0041] The second pressing assembly of this utility model includes four lifting guide rods 710, which are disposed on the flipping table 210; a lifting frame 750, which is disposed on the lifting guide rods 710 via a lifting frame sleeve 760, and the lifting frame 750 performs reciprocating linear motion along the lifting guide rods 710 via the lifting frame sleeve 760; a cylinder fixing frame 720, which is disposed on the lifting guide rods 710, and the lower end of the cylinder fixing frame 720 is fixedly connected to the top end of the lifting guide rods 710; and a second pressing cylinder 730, which is disposed above the cylinder fixing frame 720, and the cylinder body of the second pressing cylinder 730 is connected to the cylinder fixing frame 720. The cylinder mounting bracket 720 is fixed together with bolts. The cylinder rod of the second clamping cylinder 730 is connected to the top of the lifting frame 750 through the fifth pin 740. The clamping plate 790 is located below the lifting frame 750. The clamping plate 790 is fixed to the lifting frame 750 by four guide rods. One end of each guide rod is connected to the clamping plate 790, and the other end passes through the guide hole provided on the lifting frame 750 and is fixed by an anti-loosening nut. Each guide rod is also provided with a spring 780, which is located on the guide rod between the lifting frame 750 and the clamping plate 790. The second clamping assembly can fix the flipped workpiece on the flipping table 210, and the workpiece can remain vertical after flipping.

[0042] refer to Figures 1-4 As shown, the working principle of this utility model four-way flipping device is as follows: According to actual production needs, the four directions of the four-way flipping device need to flip the workpiece in which direction. Simply extend the cylinder rod of the first pressing cylinder 310 in the corresponding direction, and retract the cylinder rods of the other three first pressing cylinders 310. After the workpiece enters the flipping table, the cylinder rod of the second pressing cylinder 730 extends, driving the lifting frame 750 to move downward along the lifting guide rod 710. When the lower end face of the pressing plate 790 contacts the workpiece, the cylinder rod continues to extend, and the lifting frame 750 continues to descend. The first spring and the second spring are both deformed by force, so that the pressing plate 790 fixes the workpiece on the flipping table surface 210. The cylinder rod of the flipping cylinder 600 extends, and the flipping table 200 flips upward by 90 degrees under the action of the flipping cylinder 600, flipping the corresponding workpiece. After the flipping is completed, the cylinder rod of the second pressing cylinder 730 retracts, driving the pressing plate 790 to release the workpiece, ensuring that the workpiece remains vertical after flipping.
