[0027] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of a clamping tool for maintenance of a mechanical arm of the utility model in conjunction with the accompanying drawings.

[0028] like Figure 1-4 As shown, a clamping tool for repairing a mechanical arm of the utility model comprises a base plate 1 and a mounting hole 3, a rod body 8 is mounted on the top of the base plate 1, and the number of the rod body 8 is provided in two groups, the outside of the rod body 8 is sleeved with a sleeve 11, and the outside of the sleeve 11 is fixedly connected to a bracket 14. Due to the mounting bracket 14, it is convenient to connect the sleeve 11 with a side plate 19. One side of the bracket 14 is fixedly connected to the side plate 19, and a threaded rod 20 passes through the inside of the side plate 19. A clamping plate 16 is provided on one side of the threaded rod 20, and a rotating handle 21 is fixedly connected to the other side of the threaded rod 20. The top of the clamping plate 16 is fixedly connected to the plate body 15, and the back of the plate body 15 is fixedly connected to the sliding rod 18, and the sliding rod 18 passes through the side plate 19. By installing the threaded rod 20, the clamping plate 16, and the rotating handle 21 on the outside of the rod body 8, not only can mechanical arms of different sizes be supported, but also the compatibility is strong during clamping.

[0029] The bottom of the rod body 8 is fixedly connected to the plug rod 4, and the plug rod 4 is inserted into the top of the base plate 1. The fastening bolts 6 pass through the inside of the base plate 1 and the plug rod 4. The outside of the rod body 8 is sleeved with a sleeve 11. An inner groove 7 is opened on the top of the base plate 1. The gasket 2 is embedded in the inner groove 7. By installing the fastening bolts 6, the plug rod 4, and the sleeve 11 on the outside of the base plate 1, the maintenance tooling can be quickly disassembled and assembled. In addition, the robotic arm is large in size, which is more convenient to transfer and carry. Therefore, it is more convenient to disassemble and assemble during use.

[0030] One side of the threaded rod 20 is fixedly connected to the turntable 17 , and the other side of the turntable 17 is fixedly connected to the clamping plate 16 . Since the turntable 17 is installed, when the threaded rod 20 is twisted, the clamping plate 16 on one side will not be driven to rotate.

[0031] The outside of the rod body 8 is fixedly connected to the limit plate 9, and the inside of the sleeve 11 is provided with a limit groove 10, and the limit plate 9 is inserted into the limit groove 10. By installing the limit plate 9 and the limit groove 10, the sleeve 11 outside the rod body 8 can be limited.

[0032] A slot 5 is provided at the top of the bottom plate 1, and the insertion rod 4 is inserted into the slot 5. Due to the card and the slot 5, it is convenient to insert the insertion rod 4 at the bottom of the rod body 8 into the slot 5 at the top of the bottom plate 1 for splicing.

[0033] The back side of the sleeve 11 is fixedly connected to the internal thread seat 12, and the internal threads of the internal thread seat 12 are connected to the threaded pressing rod 13. Since the threaded seat and the threaded pressing rod 13 are installed, it is convenient to fix the position of the sleeve 11.

[0034] The working principle of the clamping tool for repairing the mechanical arm: when using the clamping tool for repairing the mechanical arm, it is first necessary to place it in the corresponding position, and then the user holds the rod body 8 to transfer it. After moving to the specified position, the rod body 8 is spliced ​​with the base plate 1. In order to facilitate the rapid disassembly and assembly of the mechanical arm, it is only necessary to insert the plug rod 4 at the bottom of the rod body 8 into the slot 5 at the top of the base plate 1, and then take out the fastening bolt 6, pass it through the base plate 1 and the plug rod 4 to fix it, and then take out the sleeve 11 and sleeve it on the outside of the limit plate 9, so as to complete the preliminary assembly. Secondly, in order to facilitate the clamping and fixation of mechanical arms of different sizes and models, an adjustable clamping structure is installed on the outside of the rod body 8. By installing the sleeve 11, threaded pressure rod 13, threaded rod 20, clamp plate 16 and other structures on the outside of the rod body 8, first adjust a group of threaded pressure rods 13 in the threaded seat of the rod body 8 according to the size of the mechanical arm, and then adjust the other A group of threaded pressure rods 13 inside the threaded seat can fix the position of the sleeve 11, and then the staff will connect the fasteners at the bottom of the mechanical arm with the mounting hole 3, and then respectively twist the threaded rods 20 on one side of the rotating handle 21 to clamp the inner clamping plate 16 on the outside of the mechanical arm. This not only can support mechanical arms of different sizes, but also has strong compatibility when clamping. After the maintenance is completed, the threaded rod 20 is twisted in the opposite direction again to remove the fasteners at the bottom of the mechanical arm from the mounting hole 3. Secondly, when it is necessary to disassemble the maintenance equipment, it is only necessary to twist the fastening bolt 6 in the opposite direction, and then pull the rod body 8 out of the slot 5 at the top of the base plate 1, and then the staff will take out the sleeve 11 outside the limit rod, and then move the gasket 2 out of the inner groove 7. In this way, the maintenance tooling can be quickly disassembled and assembled, and the mechanical arm is large in size, which is more convenient to transfer and carry, and more convenient to disassemble and assemble.
