After that, the No. 1 three-jaw chuck 4 drives the No. 1 clamping jaw 5 to close and clamp the buffer block 15, so that the outer diameter of the buffer block 15 is reduced. At the same time, the No. 2 cylinder 6 drives the push rod 7 and the suction cup 8 to descend in height, so that the bottom of the suction cup 8 contacts the top of the buffer block 15. The claw chuck 4 drives the No. 1 clamping jaw 5 to loosen and release the buffer block 15, so that the buffer block 15 is reset and installed to the installation position inside the air spring base 11, and the No. 1 cylinder 2 contracts and resets, driving the lifting frame 3 to rise, driving the No. 1 three-jaw chuck 4 and the No. 1 clamping jaw 5 to rise, at this time, the No. 2 cylinder 6 pushes the push rod 7 and the suction cylinder 8 to descend, and cooperates with the No. 1 three-jaw chuck 4 and the No. 1 clamping jaw 5 to rise and reset, so that the top of the buffer block 15 is blocked by the bottom of the suction cylinder 8, avoiding the situation that the buffer block 15 is driven by the No. 1 clamping jaw 5 to move upward, and further improving the accuracy of the installation of the buffer block 15; When the diameter of the installed buffer block 15 is small and there is no need to shrink the diameter of the buffer block 15, there is no need to use the No. 1 three-jaw chuck 4 and the No. 1 clamp 5 to clamp the buffer block 15; at this time, the No. 2 cylinder 6 pushes the push rod 7 and the suction cup 8 to descend in height, so that the suction cup 8 moves to the bottom of the No. 1 clamp 5, so that the bottom of the suction cup 8 contacts the top of the buffer block 15, and the air pump discharges the air inside the suction cup 8, so that the buffer block 15 is adsorbed on the bottom of the suction cup 8; thereafter, the No. 1 cylinder 2 pushes the lifting frame 3 to descend in height, driving the No. 2 cylinder 6, the push rod 7 and the suction cup 8 to descend in height, and inserts the buffer block 15 at the bottom of the suction cup 8 into the installation position inside the air spring base 11 for release; thereby not only facilitating the installation of buffer blocks 15 of different sizes, but also effectively avoiding the situation where the buffer block 15 is not installed in place or is installed misplaced.
