[0031] The telescopic end of the cylinder 1 is used for performing a linear telescopic motion, and the connecting rod mechanism is used for converting the linear motion into a flipping motion and driving the rotating seat 4 to rotate.

[0032] The telescopic mechanism includes a spring 17 and a telescopic plug 8. A movable groove 18 is opened in the support shaft 5, and the spring 17 and the telescopic plug 8 are both located in the movable groove 18. The two ends of the spring 17 are respectively connected to the inner wall of the movable groove 18 and the telescopic plug 8, and the end of the telescopic plug 8 that is opposite to the spring 17 passes through the movable groove 18 and is inserted into the through groove in the mounting seat 2.

At the same time, when the conical seat 21 moves downward, it can drive the guide post 25 to extend, guiding and fixing the product to be clamped. When not in use, the guide post 25 can be screwed out of the conical seat 21.

[0036] Working principle: When in use, the fixing jig 7 is designed and connected to the required equipment according to the actual working conditions. The anti-collision buffer mechanism 6 protects the overall mechanism during the feeding process. The working mode of the jaw jig is adjusted according to requirements, and its working modes are divided into two types: flipping motion and linear motion.

[0037] Flipping motion: When in use, unscrew the connecting bolt 15 from the connecting block 14, and pull out the limit pin 16 from the slider 11. Slide the slider 11 upward on the guide rail 10, so that the connecting rod 13 is removed from the connecting block 14, and insert the limit pin 16 into the slider 11 to limit the slider 11. At this time, the cylinder 1 works to drive the telescopic end to move linearly. As Figure 1 shown, when the telescopic end descends, the end of the transmission arm 3 connected to the telescopic end rotates, and at the same time, the other end of the transmission arm 3 pushes the rotating seat 4 to move. The rotating seat 4 rotates around the support shaft 5, thereby driving the jaw mechanism 9 to flip from the vertical state to the horizontal state, realizing a 90° flip. After the jaw mechanism 9 clamps the product, the cylinder 1 works to drive the telescopic end to contract, driving the product clamped by the jaw mechanism 9 to flip 90° to complete the transfer;

[0038] Linear motion: When in use, as Figure 1As shown, screw the connecting bolt 15 into the connecting block 14 to connect the connecting rod 13 with the connecting block 14. At the same time, pull out the limit pin 16 in the slider 11 to cancel the limit on the slider 11 so that the slider 11 can slide up and down on the guide rail 10. Press the telescopic insert block 8 so that the telescopic insert block 8 moves out of the through groove in the mounting seat 2. At this time, the rotating seat 4 is in an active state. The telescopic end of the cylinder 1 can directly drive the rotating seat 4 to rise or fall through the link mechanism, and the slider 11 moves in a guiding manner on the guide rail 10 to drive the rotating seat 4 to move in a guiding manner through the connecting rod 13, avoiding the situation of deviation during the linear movement of the rotating seat 4.
