Description

Technical Field

[0001] This utility model relates to the field of gripper structures, specifically a novel gripper structure. Background Technology

[0002] A gripper structure is a device used for clamping and transporting objects. It typically includes a C-shaped gripper body with a fixed clamping plate on the lower end of its opening. A hydraulic cylinder is fixedly mounted on the upper end opposite the fixed clamping plate. A movable clamping plate is fixedly mounted on the telescopic end of the hydraulic cylinder, which is driven by the hydraulic cylinder to adjust its distance relative to the fixed clamping plate. However, existing gripper structures are not convenient for the quick and stable installation and removal of the movable clamping plate, thus affecting assembly and disassembly efficiency.

[0003] To address the aforementioned problems, a novel gripper structure is proposed here. Utility Model Content

The two connecting slots are respectively engaged with the two connecting blocks, and the movable clamping plate is initially limited by the limiting engagement of the two connecting slots with the two connecting blocks.

[0009] Preferably, the bottom of the movable clamping plate is provided with several evenly distributed auxiliary grooves, which can improve the friction performance of the surface of the movable clamping plate.

[0010] Preferably, guide grooves are provided on both sides of the hydraulic cylinder, and guide rods are fixedly provided on both sides of the fixed block.

[0012] Preferably, the fixing block has a through groove in the middle, and the through groove is inserted and connected to the second fixing bolt. The through groove facilitates the installation of the second fixing bolt.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The two connecting slots engage with the two connecting blocks to initially limit the movement of the movable clamping plate. The two first fixing bolts are threaded into the two third threaded holes to initially fix the movable clamping plate. The second fixing bolt is threaded into the fourth threaded hole to further fix the movable clamping plate, thus ensuring its stable operation. By loosening the second fixing bolt and the two first fixing bolts to separate them from the two third threaded holes and the fourth threaded hole, and then pulling the movable clamping plate downward with a larger force, the two connecting slots are separated from the two connecting blocks, thus facilitating the quick disassembly and maintenance of the movable clamping plate.

A fixing block 2 is fixedly connected to the bottom end of the piston rod 14. A movable clamping plate 3 is engaged at the bottom end of the fixing block 2. A second mounting groove 8 is opened at the middle of the bottom end of the movable clamping plate 3. A first threaded hole 10 is opened on the inner side of the second mounting groove 8. A second fixing bolt 9 is threaded inside the first threaded hole 10. A fourth threaded hole 12 is opened at the connection between the piston rod 14 and the fixing block 2. The fourth threaded hole 12 is threadedly connected to the second fixing bolt 9. First mounting grooves 6 are opened on both sides of the bottom end of the movable clamping plate 3. A second threaded hole 18 is opened on the inner side of each of the two first mounting grooves 6. The interior of each hole 18 is threaded with a first fixing bolt 7. The two connecting slots 19 engage with the two connecting blocks 20 to initially limit the movement of the movable clamping plate 3. The two first fixing bolts 7 are threaded into the two third threaded holes 21 to initially fix the movable clamping plate 3. The second fixing bolt 9 is threaded into the fourth threaded hole 12 to further fix the movable clamping plate 3, thereby ensuring the stable operation of the movable clamping plate 3. By loosening the second fixing bolt 9 and the two first fixing bolts 7, they are separated from the two third threaded holes 21 and the fourth threaded hole 12. Then, by applying a larger force to pull the movable clamping plate 3 downward, the two connecting slots 19 are separated from the two connecting blocks 20, which facilitates the quick disassembly and maintenance of the movable clamping plate 3.

[0022] The bottom of the fixed block 2 has two third threaded holes 21 on both sides. The two first fixing bolts 7 are threaded to the two third threaded holes 21 respectively. Two connecting blocks 20 are fixedly installed at the connection between the fixed block 2 and the movable clamping plate 3. Two connecting slots 19 are opened at the connection between the movable clamping plate 3 and the fixed block 2. The two connecting slots 19 are engaged with the two connecting blocks 20 respectively. Several evenly distributed auxiliary grooves 22 are opened at the bottom of the movable clamping plate 3.

[0023] In use, the movable clamping plate 3 is initially fixed by the two first fixing bolts 7 respectively with the threads of the two third threaded holes 21, and the movable clamping plate 3 is initially limited by the two connecting slots 19 respectively with the limiting engagement of the two connecting blocks 20. The friction performance of the surface of the movable clamping plate 3 can be improved by the setting of several auxiliary grooves 22.

[0024] Guide grooves 5 are provided on both sides of the hydraulic cylinder 1, and guide rods 4 are fixedly provided on both sides of the fixing block 2. The two guide rods 4 are slidably connected to the two guide grooves 5 respectively. A return spring 15 is provided on the surface of the fourth threaded hole 12.

[0025] In use, the two guide rods 4 are designed to cooperate with the two guide grooves 5 to facilitate the stable movement of the fixed block 2 and the movable clamping plate 3. The reset spring 15 can play a reset role, and the through groove 11 can facilitate the installation of the second fixing bolt 9.

[0026] In use, the movable clamping plate 3 is initially limited by the two connecting slots 19 engaging with the two connecting blocks 20 respectively. The movable clamping plate 3 is initially fixed by the two first fixing bolts 7 threaded into the two third threaded holes 21 respectively. The movable clamping plate 3 is further fixed by the second fixing bolt 9 threaded into the fourth threaded hole 12, thereby ensuring the stable operation of the movable clamping plate 3. By loosening the second fixing bolt 9 and the two first fixing bolts 7, they are separated from the two third threaded holes 21 and the fourth threaded hole 12. Then, the movable clamping plate 3 is pulled down with a larger force, so that the two connecting slots 19 are separated from the two connecting blocks 20, thereby facilitating the quick disassembly and maintenance of the movable clamping plate 3.
