Description

Technical Field

[0001] This utility model relates to the technical field of locking mechanism structure for robotic arms, and in particular to a quick locking mechanism for robotic arm assembly. Background Technology

[0002] A robotic arm is an automated operating device that can mimic certain movements and functions of a human hand and arm to grasp, move objects, or operate tools according to a fixed program. Its key feature is that it can be programmed to complete various expected tasks. In terms of construction and performance, it combines the advantages of both humans and machines. During assembly, a locking mechanism is used to secure the robotic arm components. This locking mechanism is a device used for quickly and reliably connecting and fixing robotic arm components, typically used in automated production lines and robot operations to improve work efficiency and ease of operation.

[0003] A search revealed application publication number CN114347083A, which discloses a quick-locking device for an intelligent mechanical welding hand, relating to the field of welding hand technology. The device includes a lower connecting column, with an upper connecting column at its top. A central sleeve is fixedly installed on the inner wall of the lower connecting column near its center. A central rod is fitted inside the central sleeve, and a truncated cone is fixedly installed at the top of the central rod. A bent block is fixedly installed on the surface of the central sleeve near its top. The rotating base of this invention can be used to fix the intelligent mechanical welding hand. When quick installation and locking of the intelligent mechanical welding hand is required, the operator only needs to assemble the lower and upper connecting columns and then rotate the adjusting disc to lock the intelligent mechanical welding hand. Furthermore, the truncated cone allows two sets of pins to be inserted into the slots simultaneously when the adjusting disc is rotated, effectively improving the fixing firmness. This invention is highly practical and represents a significant advancement.
