[0028] Example

[0029] Reference Figures 1-4The utility model provides a technical solution: a mechanical automated grasping device, comprising a connecting rod 1 and a grasping mechanism 3, and a connecting block 2 is installed at one end of the connecting rod 1, the grasping mechanism 3 includes a movable plate 31, the movable plate 31 is slidably installed inside the connecting rod 1, and one end of the movable plate 31 is fixedly connected to the connecting block 2, a first hydraulic cylinder 311 is provided on the outside of the connecting rod 1, a driving motor 32 is stably installed on the outside of the connecting block 2, and a grasping rod 321 is installed at the output end of the driving motor 32, a connecting rod 322 is slidably installed inside the grasping rod 321, and a second hydraulic cylinder 323 is provided on the outside of the grasping rod 321, and an electric suction cup 33 is arranged at one end of the connecting rod 322.

[0030] In a preferred embodiment, the first hydraulic cylinder 311 is rotatably installed on the outside of the connecting rod 1, and the push plate 4 is fixedly installed on the outer surface of the connecting block 2. The telescopic end of the first hydraulic cylinder 311 is rotatably connected to the push plate 4. In order to facilitate the movement of the connecting block 2, the push plate 4 is installed on the outer surface of the movable plate 31, and the telescopic end of the first hydraulic cylinder 311 is rotatably connected to the push plate 4. Therefore, while pushing the movable plate 31 to move, it can also drive the connecting block 2 to move, thereby facilitating the adjustment of the position of the electric suction cup 33.

[0031] Similarly, the second hydraulic cylinder 323 is rotatably installed on the outside of the grabbing rod 321, and a rectangular plate 5 is fixedly installed on the outer surface of the connecting rod 322. The telescopic end of the second hydraulic cylinder 323 is rotatably connected to the rectangular plate 5 to push the connecting rod 322 to move. The telescopic end of the second hydraulic cylinder 323 will push the rectangular plate 5 to move, which will drive the electric suction cup 33 to move, making it easier to grab the workpiece.

[0032] In a preferred embodiment, a sliding hole 6 is opened inside one end of the connecting rod 1 and the grabbing rod 321, which is used for the moving plate 31 to slide inside the connecting rod 1 and the connecting rod 322 to slide inside the grabbing rod 321. The sliding hole 6 is provided inside the connecting rod 1 and the grabbing rod 321, which enables the moving plate 31 to slide in the sliding hole 6, and the connecting rod 322 will slide inside another sliding hole 6, so that the connecting rod 322 can move stably.

[0033] After the workpiece is sucked by the electric suction cup 33, if the workpiece falls during the transportation process, it will be damaged. To solve this problem, a supporting mechanism 7 is installed on the outside of the grabbing rod 321. The supporting mechanism 7 includes an arc plate 71, a round roller 72 and a support rod 73. The arc plate 71 is rotatably installed on the outer surface of the grabbing rod 321, and a mounting plate 8 is provided at one end of the arc plate 71. A round roller 72 is rotatably installed on the inner side of the mounting plate 8. The outer surface of the connecting rod 322 is rotatably connected to the support rod 73. The support rod 73 is provided at a position on the inner side of the arc plate 71 and corresponds to the position of the arc plate 71. One end of the support rod 73 is rotatably connected to the inner side surface of the arc plate 71 for pushing the arc plate 71 to rotate.

[0034] In actual use, in order to prevent the workpiece from falling, when the telescopic end of the second hydraulic cylinder 323 is extended, the support rod 73 will be driven to rotate. During the rotation process, the support rod 73 will rotate the arc plate 71, so that the two arc plates 71 are opened so that the electric suction cup 33 can grab the workpiece. After suction, the telescopic end of the second hydraulic cylinder 323 will retract and drive the support rod 73 to rotate. During the rotation process, the arc plate 71 will be driven to rotate, controlling the openings of the two arc plates 71 to become smaller, and moving the round roller 72 to the bottom of the workpiece, thereby preventing the workpiece from falling and causing damage.

[0035] Specifically, the working process or working principle of a mechanical automated grasping device is as follows: the current way to transfer workpieces is for the staff to remove the workpieces from the conveying equipment and place them in the processing position on the processing equipment to realize the processing of the workpieces. Although this operation can transfer and process parts, it is done through manual operation, which not only wastes time, but also increases the labor intensity of the staff and reduces work efficiency. Therefore, this device is designed to solve this problem.

[0036] This device can automatically grab parts and components, making it convenient to transfer the workpiece to the location of the processing equipment for processing the workpiece, effectively replacing manual operation, saving time and improving work efficiency. The specific operation is to stably install the device at the location where it needs to be used and connect it to an external power supply. When the workpiece needs to be grabbed, the device is adjusted according to the position of the workpiece. If the position of the workpiece is far from the position of the device, the first hydraulic cylinder 311 can be opened first, and the connecting block 2 can be pushed to move by the first hydraulic cylinder 311, thereby driving the position of the electric suction cup 33 and moving the electric suction cup 33 to be directly above the workpiece.

[0037] Then open the second hydraulic cylinder 323, and push the connecting rod 322 downward through the telescopic end of the second hydraulic cylinder 323, so that the electric suction cup 33 contacts the outer surface of the workpiece, so that the electric suction cup 33 can suck the workpiece, thereby grabbing the workpiece, and controlling the rotation of the device to move the workpiece to the processing equipment for easy processing of the workpiece.

[0038] If the surface of the workpiece to be grasped is an inclined surface, when grasping the workpiece, the grasping rod 321 can be driven to rotate by the driving motor 32, and the electric suction cup 33 can be adjusted to move above the workpiece and be parallel to the workpiece suction surface. Then, the second hydraulic cylinder 323 is opened, and the connecting rod 322 is pushed to move by the telescopic end of the second hydraulic cylinder 323 to make the electric suction cup 33 contact the workpiece so that the workpiece can be grasped for easy use.

[0039] In actual operation, after the workpiece is grasped, in order to prevent the workpiece from falling, the device will drive the support rod 73 to rotate when the telescopic end of the second hydraulic cylinder 323 is extended. The support rod 73 will rotate the arc plate 71 during the rotation process, so that the two arc plates 71 are opened so that the electric suction cup 33 can grasp the workpiece. After suction, the telescopic end of the second hydraulic cylinder 323 will retract and drive the support rod 73 to rotate. During the rotation process, the arc plate 71 will be driven to rotate, controlling the openings of the two arc plates 71 to become smaller, and moving the round roller 72 to the bottom of the workpiece, thereby preventing the workpiece from falling and facilitating use.

[0040] It should be noted that the drive motor 32 and the electric suction cup 33 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they will not be described in detail.
