水下连接器卡爪工装研制与应用

Development and Application of Underwater Connector Jaw Tooling

水下连接器是深海水下生产系统的关键设备,为保障水下产品使用可靠性,卡爪采用了高强度材料,设计有复杂的结构,筒形毛坯尺寸多、质量大但基准面小,整体定位及分度加工困难。文中针对卡爪的加工难点,通过研究其结构特点,制定了工艺方案,进行了工装研制。把筒形工件刚性装夹改进为滚珠滚动支撑,并通过设置相对固定又能分度的承载、扶正机构,可进行加工中微调又相对夹紧,满足了水下连接器卡爪的加工,并研究了应用该工装实现自动化制造的方案,为类似结构工件的加工制造提供借鉴。

The underwater connector belongs to the key equipment of the deep-sea underwater production system,in order to ensure the reliability of the product,the claw adopts high strength material,the design has complex structure,the integral cylinder blank size is many,the weight is big but the reference plane is small,the overall positioning and indexing machining is difficult.In this article,according to the machining difficulties of claw,through the study of its structural characteristics,the process scheme is worked out,and the tooling is developed.The rigid clamping of cylinder workpiece is innovated into ball rolling support,and the fine adjustment and relative clamping in machining can be carried out by setting up relatively fixed and dividing bearing and centralizing mechanism,which satisfies the machining of underwater connector claw,and the scheme of automatic manufacturing by using this tool is studied,which is used to manufacture similar structural workpiece.
