[0001] The utility model relates to the technical field of pin disassembly and assembly tools, in particular to a pin assembly and disassembly tool for a robot. Background Art

[0002] A robotic arm is an automated mechanical device that is widely used in the field of robotics. The joints in the robotic arm connect the rotating or sliding parts of the various parts of the robotic arm, allowing the robotic arm to move flexibly. Pins are usually installed at the joints of the robotic arm. When maintaining the robotic arm, it is usually necessary to install and disassemble the pins.

[0003] When installing the pin body, in order to facilitate the subsequent installation of the baffle, the three mounting holes on the pin body need to be aligned with the two mounting holes on the robot arm, that is, all the holes are installed in a straight line. The traditional installation method is that the operator judges the position by naked eyes, which easily leads to large installation errors, is not convenient for the hole alignment of the baffle, and even requires multiple adjustments to the position of the pin body, resulting in low installation efficiency, low pin body installation accuracy, and poor installation quality;

[0004] When removing the pin body, the operator needs to manually apply force to pull the pin body, which makes the removal of the pin body difficult and increases the workload of the operator.

[0005] In view of this, a tool is designed to facilitate the installation and disassembly of the pin body.

[0006] There may already be technical means to solve the above problems in the prior art, but this case intends to provide an alternative or replacement technical solution. Utility Model Content
