繁體:支撐臂/支架
支撑臂和支架是工业机械中集成到夹具或载体上的精密结构件,用于固定、对齐和支撑工件或子组件。
支撑臂和支架是精密设计的结构元件,集成到工业机械的夹具或载体中。这些部件作为刚性安装点,在加工、装配、焊接或检测操作中固定、对齐和支撑工件或子组件。它们通过抵抗操作力、热膨胀和振动引起的变形来保持尺寸精度,同时确保自动化过程的可重复定位。 支撑臂/支架通过机械刚度和几何约束发挥作用。它们通过杠杆臂或直接安装将载荷从工件传递到夹具底座,利用静力平衡原理防止移动。可调版本包含滑动机构、锁定销或螺纹元件,以适应不同的工件尺寸,同时通过精密磨削表面和对齐特征保持位置精度。

Support arms typically refer to elongated structural members that extend from the fixture base to contact workpieces at specific points, often with adjustable ends. Brackets are usually L-shaped or U-shaped mounting plates that provide attachment points between different fixture components. Both serve load-bearing functions but differ in geometry and typical applications.
Material selection depends on load requirements, environmental conditions, and weight constraints. Steel alloys offer maximum strength for heavy loads, aluminum provides good strength-to-weight ratio for automated systems, and stainless steel resists corrosion in harsh environments. Consider thermal expansion coefficients when operating across temperature ranges.
