[0027] Working principle: according to the diameter of the blank, adjust the distance between the two sides of the limiting plate 15, rotate the rocker of the worm, make the worm drive the worm gear 22 to rotate, the worm gear 22 drives the threaded rod 23 at both ends to rotate, that is, the two sides of the limiting plate 15 can slide synchronously in reverse, change the distance between the two sides of the limiting plate 15, place the blank to be punched vertically on the conveying belt 4 between the two groups of limiting plates 15, and drive the rotating cylinder 8 with the driving roller 6 to make the conveying belt 4 transmission, conveying the blank on the upper side to the end close to the first guide rod 13, when the blank touches the pressure sensor 43 on the side of the first guide rod 13, it indicates that the blank to be fed has been conveyed in place, at this time stop the transmission of the conveying belt 4, until the mechanical claw 27 on the mechanical arm 25 takes away the blank close to the first guide rod 13, then start the driving roller 6 to rotate and convey again.

[0028] In the process of intermittent operation of the driving roller 6, the first electric telescopic rod 19 also operates intermittently, first pushes the connecting plate 9 and the connecting frame 10 to make the fixed ring 11 drive the rotating cylinder 8 and the conveying belt 4 to slide, when the trigger key 20 on the limiting block 18 on one side touches the side of the limiting rod 17, it indicates that the conveying belt 4 has been moved to the maximum displacement at this time, continue to move will appear blank bottom surface not on the conveying belt 4, at this time the trigger key 20 controls the first electric telescopic rod 19 to pull back, and controls the first electric telescopic rod 19 to pull back a small distance every time the driving roller 6 starts, changes the friction position between the conveying belt 4 and the bottom surface of the blank, so that the surface of the conveying belt 4 can be fully used, because when processing different sizes of piston pin, the diameter of the blank is different, if all use the middle position of the conveying belt 4 to convey, it will cause the middle position of the conveying belt 4 to wear seriously even concave, and the both sides are less used, eventually showing the middle concave and both sides high, affecting the subsequent conveying of the blank, reducing the stability and service life of the conveying belt 4, therefore, the above structure solves the problem, ensures that the outer wall of the conveying belt 4 can be fully used, the overall wear is more uniform and smooth, improves the conveying stability, prolongs the service life of the equipment.

[0029] The blank is clamped by a set of mechanical claws 27 and conveyed into the punch 2, at this time another set of idle mechanical claws 27 can clamp and take out the punched piston pin inside the punch 2, after taking out, the mechanical claws 27 clamping the blank are directly switched to the mold shell 41 at the set position, the placement of the blank is monitored and judged by the photoelectric sensor 42, if the position is not accurate, the mechanical claws 27 need to be controlled to assist in correcting the position of the blank, after the blank feeding operation is completed, the punch 2 can be started for punching operation, and the mechanical arm 25 controls the punched piston pin to be placed on the driving cylinder 31 and the rolling cylinder 34, the switching use of the two sets of mechanical claws 27 can effectively improve the automation degree and operation efficiency of feeding and discharging, at this time the upper surfaces of the driving cylinder 31 and the rolling cylinder 34 are flush, the diameters of the driving cylinder 31 and the rolling cylinder 34 are the same, the driving cylinder 31 drives the piston pin to rotate, and at the same time drives the rolling cylinder 34 to roll, the coaxiality of the rotating piston pin can be detected by the laser displacement sensor 35, when the product is qualified, the rotating table 29 is rotated to the side facing the first collecting box 37 together with the conveying frame 40, the second electric telescopic rod 32 is started to lift the rolling cylinder 34, at this time the upper piston pin will roll to the conveying frame 40 on the side of the driving cylinder 31, and is conveyed to the first collecting box 37 through the guide frame 39 for collection, similarly, when the product is unqualified, the conveying frame 40 is turned to the second collecting box 38, and the piston pin is conveyed to the second collecting box 38 for storage, after the piston pin is output, the second electric telescopic rod 32 drives the lifting block 33 and the rotating cylinder to move downward again, so that the rotating cylinder is flush with the driving cylinder 31, and subsequent detection can be performed.

[0030] It is worth noting that: the conveying belt 4 is driven to slide by the rotating cylinder 8 and the fixed rings 11 on both sides instead of directly driving the conveying belt 4 to slide on the outer wall of the driving roller 6, which reduces the wear of the inner wall of the conveying belt 4 during adjustment, and greatly reduces the friction coefficient during horizontal sliding adjustment by lubricating between the rotating cylinder 8 and the outer wall of the driving roller 6, thereby improving the efficiency of adjusting the conveying belt 4, and the adjustment operation is more smooth and stable.
