矿用防爆灯外壳车加工专用夹具的设计研究

Mine Explosion-proof Light Fixture Shell of Car Processing Design

矿用防爆灯具铝合金壳体铸件上的接线嘴一般对称设置在壳体的两侧或偏心设置在同一端面上,使用常规夹具加工接线嘴内孔及其内螺纹具有一定的难度。通过设计一种采用手动机械夹紧方式的专用夹具对此类零件装卡加工,使夹具具有设计结构简单、制造成本低廉、具有自动定心功能且重复定位准确、无需调整找正,操作方便、安全快捷的特点,特别适应于大批量产品零件的生产。

Mine explosion-proof aluminum alloy shell lamp cast on the general symmetry of the wiring installed in the mouth on both sides of the shell or end in the same eccentric level settings, the use of conventional machining fixture wiring inside the mouth hole and thread with a certain degree of difficulty. Manually through the design of a dedicated mechanical clamping fixture means such parts of the card processing equipment to the design of fixture with a simple structure, low manufacturing costs, with automatic centering function and repeat positioning accuracy, there is no need to adjust is to find, easy to operate , safety features and quick, especially adapted to the production of a large number of product parts.
