AI Technical Summary

Technical Problem

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.

Method used

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.

Benefits of technology

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.

Abstract

多用途联轴器抓具,属于机械装配领域。本实用新型包括抓具、胎具、拉杆、套筒、卡环和固定螺栓,拉杆两端分别与抓具和胎具铰接,抓具和胎具的中心轴线重合,所述拉杆设置四个,以抓具和胎具的中心轴线为基准,均匀圆周环绕阵列布置,胎具为两半式结构,两半式结构左右对称设置,且通过固定螺栓连接,胎具内侧卡装有套筒,胎具外侧底部卡装有卡环。目的是为了解决现有保护性拆除工具如拉马、焊接龙门架、顶床存在的受力不均易滑脱、热变形影响精度、需设备转运耗时、互换性差以及无法适应大尺寸或过盈配合的问题,避免破坏性拆除方法如气焊切割、机床加工带来的损伤配合面及邻近部件风险、长时间冷却等待以及设备转运或加工耗时等弊端。
