Description

Technical Field

[0001] This utility model belongs to the technical field of stamping automated production operation device, specifically relating to a stamping automated production gripper telescopic mechanism. Background Technology

[0002] When producing the wheel cover oil filler reinforcement part using a five-stage mold, the current method involves directly using a robotic arm's suction cup to pick up the part and feed it in. However, during the part feeding process, due to limitations in product shape and mold design, the distance between the two plates in the final stage may increase or decrease. Therefore, the traditional robotic arm structure cannot meet the requirements. Moreover, relying solely on the robotic arm to adjust the angle for feeding often leads to parts being fed off-center, severely impacting production cycle time, causing frequent line stoppages, wasting equipment resources, and increasing the probability of errors throughout the production process. Therefore, it is necessary to improve the structure of the existing automated stamping production robotic gripper. Utility Model Content

[0003] This utility model addresses the aforementioned problems by providing a lightweight, easy-to-install, and applicable stamping automation production gripper telescopic mechanism that is suitable for the production of various similar products, effectively improves production efficiency, and is easy to maintain.

[0004] The technical solution adopted by this utility model is as follows: the telescopic mechanism of the stamping automation production gripper includes a fixed connecting rod connected to the lifting mechanism. The fixed connecting rod has a rotating connecting frame at each end, and a rotating crossbeam is rotatably mounted on the lower side of each rotating connecting frame. A rotating drive mechanism is provided between the rotating crossbeam and the rotating connecting frame. Furthermore, a telescopic crossbar is also provided on the lower side of each rotating connecting frame. The two ends of the rotating crossbeam are connected to the telescopic crossbar via the telescopic drive mechanism. Several sets of parallel suction cup mounting longitudinal bars are provided on the telescopic crossbar. The suction cup mounting longitudinal bars are connected to the telescopic crossbar via crossbar and longitudinal bar connectors. Several vacuum suction cups are provided on the suction cup mounting longitudinal bars.

[0005] The rotary drive mechanism includes a rotary drive cylinder. One end of the rotary drive cylinder is hinged to a rotary cylinder hinge lug on the rotary connecting frame, and the other end is connected to the upper end of the rotary hinge shaft via a rotary swing connecting rod. The lower end of the rotary hinge shaft is connected to a rotary hinge seat in the middle of the rotary beam, and the rotary hinge shaft is also rotatably connected to the rotary connecting frame via a rotary bearing seat. The extension and retraction of the rotary drive cylinder drives the rotary swing connecting rod connected to the rotary hinge shaft to reciprocate, thereby driving the rotary beam, the telescopic crossbar, and the suction cup mounting rod on them to rotate together around the rotary hinge shaft in the horizontal plane at a certain angle, changing the suction angle of the vacuum suction cup.

[0006] The telescopic drive mechanism includes a three-axis, three-bar telescopic cylinder located at the end of the rotating crossbeam. The cylinder is arranged longitudinally, with its fixed cylinder body fixedly connected to the end of the rotating crossbeam. The telescopic end of the cylinder is connected to the telescopic crossbar via a telescopic rod connecting seat. The telescopic movement of the cylinder drives the telescopic crossbar, its suction cup mounting rod, and the vacuum suction cup to extend or retract longitudinally, thereby changing the suction position of the vacuum suction cup.

[0007] The crossbar and longitudinal bar connector includes a crossbar connecting block. The middle of the crossbar connecting block has a crossbar insertion hole for connecting to a telescopic crossbar. The upper end of the crossbar connecting block has a connecting block locking opening, which communicates with the upper part of the crossbar insertion hole. Furthermore, the side of the connecting block locking opening also has a locking bolt hole. The lower part of the crossbar connecting block has a longitudinal bar connecting sleeve for connecting to the suction cup mounting longitudinal bars. Several suction cup mounting longitudinal bars can be connected to the telescopic crossbar via the crossbar and longitudinal bar connector. The locking bolts located in the locking bolt holes press against the connecting block locking opening, thereby locking the position of the suction cup mounting longitudinal bars.

[0008] The vacuum suction cup is connected to the suction cup mounting rod via a threaded upright and a locking nut. This facilitates adjustment of the vacuum suction cup's height and makes it easy to replace.

[0009] The beneficial effects of this utility model are as follows: Because this utility model uses a fixed connecting rod connected to a lifting mechanism, with rotating connecting frames at both ends of the fixed connecting rod, and rotating crossbeams rotatably mounted on the lower sides of the rotating connecting frames at both ends, a rotating drive mechanism is provided between the rotating crossbeams and the rotating connecting frames, and telescopic crossbars are provided on the lower sides of the rotating connecting frames, with both ends of the rotating crossbeams connected to the telescopic crossbars via the telescopic drive mechanism, and several sets of parallel suction cup mounting longitudinal bars are provided on the telescopic crossbars. These suction cup mounting longitudinal bars are connected to the telescopic crossbars via crossbar and longitudinal bar connectors, and the suction cup mounting longitudinal bars are equipped with several vacuum suction cups. Therefore, its design is reasonable, its structure is compact, the overall weight of the mechanism is light, manual installation is convenient, the connecting parts can be freely adjusted, it can be applied to the production of various similar products, effectively improving production efficiency, and each component adopts an independent structure that is easy to disassemble, facilitating maintenance.

[0015] according to Figures 1-4 The specific structure of this utility model is described in detail. The telescopic mechanism of the stamping automation production gripper includes a fixed connecting rod 1 connected to a lifting mechanism such as a feeding robot. Rotary connecting frames 2 are respectively provided at both ends of the fixed connecting rod 1. Rotary crossbeams 4 are rotatably mounted on the lower sides of the rotary connecting frames 2 at both ends. A rotary drive mechanism 3 is provided between the rotary crossbeams 4 and the rotary connecting frames 2. The rotary drive mechanism 3 includes a rotary drive cylinder 10. The fixed end of the rotary drive cylinder 10 is hinged to a rotary cylinder hinge lug 11 provided at one end of the rotary connecting frame 2. The telescopic end of the rotary drive cylinder 10 is connected to the upper end of a rotary hinge shaft 14 vertically arranged at the other end of the rotary connecting frame 2 via a rotary swing connecting rod 13. Furthermore, the lower end of the rotary hinge shaft 14 is connected to a rotary hinge seat 12 provided in the middle of the rotary crossbeam 4. The rotary hinge shaft 14 is also rotatably connected to the rotary connecting frame 2 via a rotary bearing seat 15. Furthermore, the extension and retraction of the rotary drive cylinder 10 is used to drive the rotary swing link 13 connected to the rotary hinge shaft 14 to swing back and forth, thereby driving the rotary crossbeam 4, the telescopic crossbar 6, and the suction cup mounting rod 7 (including the vacuum suction cup 9) on it to rotate together around the rotary hinge shaft 14 in the horizontal plane at a certain angle, thereby changing the adsorption angle of the vacuum suction cup 9.

[0016] Meanwhile, on the lower side of the rotating connecting frame 2 at both ends of the fixed connecting rod 1, telescopic crossbars 6 are respectively provided. The telescopic crossbars 6 are arranged parallel to the rotating beam 4, and both ends of the rotating beam 4 are connected to the telescopic crossbars 6 through the telescopic drive mechanism 5. The telescopic drive mechanism 5 includes a three-axis three-bar telescopic cylinder 16 located at the end of the rotating beam 4. The three-axis three-bar telescopic cylinder 16 is arranged longitudinally. The fixed cylinder body of the three-axis three-bar telescopic cylinder 16 is fixedly connected to the end of the rotating beam 4, and the telescopic end of the three-axis three-bar telescopic cylinder 16 is connected to the telescopic crossbar 6 through the telescopic rod connecting seat 17. Thus, by extending and retracting the three-axis three-bar telescopic cylinder 16, the telescopic crossbar 6 and the suction cup mounting rod 7 and vacuum suction cup 9 on it are driven to extend or retract longitudinally, changing the adsorption position of the vacuum suction cup 9.

[0017] The telescopic crossbar 6 is equipped with several sets of parallel suction cup mounting rods 7. These rods are arranged perpendicularly to the telescopic crossbar 6 in the horizontal plane. Each suction cup mounting rod 7 is connected to the telescopic crossbar 6 via a crossbar-vertical rod connector 8. Several vacuum suction cups 9 are mounted on the suction cup mounting rods 7, and these suction cups 9 are connected to a vacuum generator via pipes. The vacuum suction cups 9 are connected to the suction cup mounting rods 7 via threaded uprights and locking nuts, facilitating height adjustment and replacement of the vacuum suction cups 9.

[0018] The crossbar and longitudinal bar connector 8 is composed of a crossbar connecting block 18. The crossbar connecting block 18 has a crossbar insertion hole 19 in its middle for connecting to the telescopic crossbar 6. The upper end of the crossbar connecting block 18 has a connecting block locking opening 20, which extends downwards and communicates with the upper part of the crossbar insertion hole 19. Furthermore, the side of the connecting block locking opening 20 also has a locking bolt hole 21. Additionally, the lower part of the crossbar connecting block 18 has a longitudinal bar connecting sleeve 22 for connecting to the suction cup mounting longitudinal bar 7. Several suction cup mounting longitudinal bars 7 are then connected to the telescopic crossbar 6 via the crossbar and longitudinal bar connector 8. The locking bolts located in the locking bolt holes 21 are used to press the connecting block locking opening 20, thereby locking the position of the suction cup mounting longitudinal bars 7.

[0019] When this automated stamping production gripper telescopic mechanism is in use, as the distance between the last two plates increases or decreases, the telescopic crossbar 6, along with the suction cup mounting rod 7 and vacuum suction cup 9, extends or retracts longitudinally through the extension and retraction of the three-axis, three-bar telescopic cylinder 16, thereby changing the suction position of the vacuum suction cup 9. Simultaneously, the extension and retraction of the rotary drive cylinder 10 drives the rotary swing linkage 13 connected to the rotary hinge shaft 14 to swing back and forth, thereby driving the rotary crossbeam 4, the telescopic crossbar 6, and the suction cup mounting rod 7 and vacuum suction cup 9 to rotate together around the rotary hinge shaft 14 in the horizontal plane at a certain angle, changing the suction angle of the vacuum suction cup 9. This improves the situation where traditional structure manipulators cannot meet the usage requirements and often cause parts to be misaligned, effectively improving production efficiency.
