AI Technical Summary
Existing coupling removal tools suffer from uneven force distribution leading to slippage, thermal deformation affecting accuracy, the need for equipment transportation resulting in time consumption, poor interchangeability, and the risk of damage from destructive removal. Furthermore, the operation is complex and time-consuming.
A multi-purpose coupling gripper was designed, which adopts a uniformly circumferentially distributed tie rod structure and a two-half jig/sleeve design. Combined with sleeve positioning and snap ring fixing, it achieves coaxial force and is suitable for couplings of various models and sizes.
It enables efficient and safe removal of couplings on-site, avoiding thermal impact and equipment deformation, shortening maintenance cycles, improving tool interchangeability and reusability, and reducing the cost of special tooling.
