[0002] A mechanical gripper is a device that uses mechanical design and a drive system to grasp and manipulate objects. With the help of mechanical grippers, tasks such as handling, palletizing, and loading / unloading can be performed, thereby improving production efficiency and quality, reducing the labor intensity of workers, and replacing workers in some dangerous and repetitive tasks, ensuring their personal safety. For example, there is a semi-automatic assisted mechanical gripper with the existing technology publication number CN219617803U. In the production process of ring-shaped splitters, they need to be transferred, but this transfer process poses significant safety hazards and is labor-intensive. Due to the negative growth of factory employees and the high risk of accidents during transfer, some companies use forklifts for transfer.
[0003] However, when using forklifts for transport, there is a lack of tools to place the products into the metal boxes, and after transporting the ring-shaped box, a hand-pushed forklift is needed to complete the transfer of the products. Due to the high temperature and weight of the products, the transfer process is labor-intensive and poses certain safety hazards. Based on this, this utility model provides a highly safe semi-automatic mechanical gripper. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Refer to the instruction manual appendix Figures 1-5 This utility model provides a semi-automatic mechanical gripper, including a fixed frame 1 connected to a crane mechanism 2. Specifically, the crane mechanism 2 includes a cantilever crane 21, with a cantilever beam 22 at its front end. The cantilever beam 22 is fixed to the cantilever crane 21 via a rotating shaft 23. A cantilever hoist 24 is mounted on the cantilever beam 22, and a chain 25 is wound around the cantilever hoist 24. A hook 26 is fixed to the bottom of the chain 25, and the hook 26 is connected to the fixed frame 1. In actual use, a hook 26 with a self-locking structure (such as...) is selected. Figure 1 As shown in the figure, it is ensured that it will not fall off during use. The fixed frame 1 is moved by the crane mechanism 2, which can improve the transfer efficiency of the ring splitter box.
[0025] The bottom of the fixed frame 1 is connected to a gripper mechanism 3, which is composed of multiple connecting rods 31 and multiple connecting shafts 32. A cylinder 4 is fixedly installed inside the fixed frame 1. A telescopic rod 5 is provided at the bottom of the cylinder 4. The bottom of the telescopic rod 5 is connected to the connecting rod 31 through an opening and closing control chain 6. An operating rod 7 is fixedly installed at the front end of the fixed frame 1. A conversion solenoid valve 8, a cylinder control switch 9, and a crane control switch 10 are fixedly installed at the top of the operating rod 7. The conversion solenoid valve 8 can control the gas flow direction and on / off state of the cylinder 4.
[0026] The cylinder 4 is fixedly provided with an air inlet / outlet control pipe 11 at its front end. The air inlet / outlet control pipe 11 is located above the operating lever 7. The air inlet / outlet control pipe is connected to the air pump and the cylinder 4, and the air pressure is adjusted to control the gripping force.
[0027] In actual use, first, the fixed frame 1 is locked to the hook 26. Then, the operator holds the operating lever 7 and controls the cantilever crane 21 to move the fixed frame 1 to the ring splitter box through the crane control switch 10. Then, the cylinder control switch 9 and the switching solenoid valve 8 use the cylinder 4 to drive the telescopic rod 5 to move upward. The telescopic rod 5 pulls the gripper mechanism 3 to open and perform a gripping action through two opening and closing control chains 6. Then, the cantilever crane 21 is used to transfer the ring splitter box to the designated position. Then, the cylinder 4 is controlled to drive the telescopic rod 5 to extend. The two opening and closing control chains 6 are released, causing the gripper mechanism 3 to open automatically, so that the ring splitter box is moved out of the gripper mechanism 3, thus completing the transfer of the ring splitter box.
[0028] Refer to the instruction manual appendix Figures 1-5 The operating lever 7 includes a lever body 71 and a lever head 72. The lever head 72 is detachably fixed on the fixing frame 1. A groove 73 is provided at one end of the lever head 72 near the lever body 71. A rotating shaft 74 is fixedly passed through one end of the lever body 71 near the lever head 72. The lever body 71 is connected to the groove 73 through the rotating shaft 74, so that the lever body 71 can rotate relative to the lever head 72.
[0029] Electromagnetic locks 12 are fixedly provided at the top and bottom of the rod head 72, and limiting plates 13 are fixedly provided at the top and bottom of the rod body 71. Lock grooves 14 adapted to electromagnetic locks 12 are fixedly embedded on both limiting plates 13.
[0030] After the transfer is completed, first move the latch of the electromagnetic lock 12 at the bottom of the control rod 72 out of the lock groove 14, and then grasp the rod body 71 to fold it so that the rod body 71 is close to the fixing frame 1. This can reduce the space occupied by the rod body 71. After the rod body 71 is folded, use the electromagnetic lock 12 above the rod head 72 to lock the lock groove 14 for fixation, which can prevent the rod body 71 from being damaged by collision after automatically flipping over.
[0031] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
