Description

Technical Field

[0001] This invention relates to the field of stamping equipment technology, specifically to an automated loading and unloading device for piston pin stamping. Background Technology

[0002] As a key force-transmitting component connecting the piston and connecting rod, the piston pin must possess high strength, high wear resistance, and precise dimensional accuracy. In its manufacturing process, the stamping process (including cutting, upsetting, and initial forming) is the core link that determines the quality of the piston pin blank. As the connecting node of the stamping process, the efficiency and accuracy of loading and unloading directly affect the overall production rhythm and product qualification rate.

[0003] Currently, domestic piston pin manufacturers still mainly rely on manual or semi-automatic loading and unloading methods in the stamping process. The positioning accuracy is difficult to meet the standards, and the safety risks are relatively high. The equipment has a low degree of automation during operation, making it difficult to monitor and adjust the wear of the conveying equipment simultaneously during loading and unloading. This results in uneven wear of the conveying equipment and affects the stability of the product transportation process. Summary of the Invention

The threaded rods 23 pass through a limiting plate 15 and are threadedly connected to the limiting plate 15.

[0036] The handling mechanism includes a control console 24 fixedly mounted on a base 1. A robotic arm 25 is fixedly connected to the control console 24. A rotating frame 26 is rotatably connected to the robotic arm 25. Two sets of robotic grippers 27 are provided on the rotating frame 26. Each set of robotic grippers 27 is equipped with a sensor 28. The sensor 28 is used to sense whether there is a product being gripped on the robotic gripper 27.

[0037] The output mechanism includes a rotating platform 29 rotatably connected to the base 1. Two sets of fixed frames 30 are fixedly connected to the rotating platform 29. A drive cylinder 31 is rotatably connected between the two sets of fixed frames 30. The drive cylinder 31 can rotate. A second electric telescopic rod 32 is fixedly connected to the rotating platform 29. A lifting block 33 is fixedly connected to the telescopic end of the second electric telescopic rod 32. A rolling cylinder 34 is rotatably connected to the lifting block 33. A laser displacement sensor 35 is fixedly connected to the upper side of the fixed frame 30. The laser displacement sensor 35 is used to detect the coaxiality of the product. A collection component 36 for classifying and collecting the product is provided on the base 1.

[0038] The collection component 36 includes a first collection box 37 and a second collection box 38 fixedly installed on the base 1. The first collection box 37 is used to collect qualified products, and the second collection box 38 is used to collect unqualified products. Two sets of guide frames 39 are fixedly connected to the base 1, and the two sets of guide frames 39 are respectively facing the first collection box 37 and the second collection box 38. A conveyor frame 40 is fixedly connected to the rotating table 29.

[0039] Working principle: Adjust the distance between the two limiting plates 15 according to the diameter of the blank, rotate the rocker at one end of the worm gear, so that the worm gear drives the worm wheel 22 to rotate, and the worm wheel 22 drives the threaded rods 23 at both ends to rotate, so that the two limiting plates 15 can slide synchronously in opposite directions, changing the distance between the two limiting plates 15. Place the blank to be stamped vertically on the conveyor belt 4 between the two sets of limiting plates 15, and the drive roller 6 drives the rotating drum 8 to drive the conveyor belt 4 to transport the blank on the upper side to the end near the first guide rod 13. When the blank touches the pressure sensor 43 on the side of the first guide rod 13, it means that the blank to be fed has been transported to the right position. At this time, stop the transmission of the conveyor belt 4 until the mechanical claw 27 on the robotic arm 25 takes away the set of blanks near the first guide rod 13, and then restart the drive roller 6 to rotate and transport.

[0040] During the intermittent operation of the drive roller 6, the first electric telescopic rod 19 also operates intermittently. It first pushes the connecting plate 9 and the connecting frame 10, causing the fixed ring 11 to drive the rotating drum 8 and the conveyor belt 4 to slide. When the trigger key 20 on one side of the limit block 18 contacts the side of the limit rod 17, it indicates that the conveyor belt 4 has moved to its maximum displacement. Continuing to move it will result in the bottom surface of the billet not being on the conveyor belt 4. At this time, the trigger key 20 controls the first electric telescopic rod 19 to pull back. Furthermore, each time the drive roller 6 starts, the first electric telescopic rod 19 is pulled back a small distance, changing the friction between the conveyor belt 4 and the bottom surface of the billet. The design of the conveyor belt 4 ensures that its surface is fully utilized. Since the diameter of the blanks varies when processing piston pins of different sizes, if the middle section of the conveyor belt 4 is used for all conveying, the middle section will suffer severe wear and even become concave, while the sides will be used less frequently. This results in a concave middle and high sides, affecting subsequent blank conveying, reducing the stability and service life of the conveyor belt 4. Therefore, the above structure solves this problem, ensuring that the outer wall of the conveyor belt 4 is fully utilized, resulting in more uniform and smooth wear, improved conveying stability, and extended equipment lifespan.

[0041] The blank is gripped by a set of mechanical claws 27 and conveyed into the stamping press 2. At this time, another set of idle mechanical claws 27 can grip and remove the piston pin that has been stamped inside the stamping press 2. After removal, the mechanical claws 27 holding the blank are directly switched to the mold cover 41 in the set position. The placement of the blank is monitored and judged by the photoelectric sensor 42. If the position is inaccurate, the mechanical claws 27 need to be controlled to assist in correcting the position of the blank. After the blank loading operation is completed, the stamping press 2 can be started to perform the stamping operation. Then, the robotic arm 25 is controlled to place the stamped piston pin onto the drive cylinder 31 and the rolling cylinder 34. The switching of the two sets of mechanical claws 27 can effectively improve the automation level and operation efficiency of loading and unloading. At this time, the upper surfaces of the drive cylinder 31 and the rolling cylinder 34 are flush. The piston pins are of the same diameter. The piston pin is driven to rotate by the drive cylinder 31, which in turn 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 and the conveying frame 40 are rotated together to face the first collection box 37. The second electric telescopic rod 32 is activated to lift the rolling cylinder 34. At this time, the piston pin on the upper side will roll to the drive cylinder 31 into the conveying frame 40 and be conveyed to the first collection box 37 for collection by the guide frame 39. Similarly, when the product is unqualified, the conveying frame 40 is turned to the second collection box 38 and the piston pin is conveyed to the second collection 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 down again, so that the rotating cylinder is flush with the drive cylinder 31 for subsequent testing.

[0042] It is worth noting that the conveyor belt 4 is slidably adjusted by rotating the cylinder 8 and the fixed rings 11 on both sides instead of directly sliding the conveyor belt 4 on the outer wall of the drive roller 6. This reduces the wear on the inner wall of the conveyor belt 4 during the adjustment process. At the same time, since the rotating cylinder 8 and the outer wall of the drive roller 6 can be lubricated, the coefficient of friction during horizontal sliding adjustment is greatly reduced, improving the efficiency of adjusting the conveyor belt 4 and making the adjustment operation smoother and more stable. Both the drive roller 6 and the drive cylinder 31 are equipped with motors that can drive them to rotate.
