定义
The Arm Body is the primary structural component of a Tool Change Arm, engineered to withstand dynamic loads during high-speed tool exchange operations. It serves as the mounting platform for grippers, sensors, and drive mechanisms while maintaining precise alignment between the spindle and tool magazine. This component ensures vibration damping, thermal stability, and protection of internal components in industrial automation environments.
工作原理
The Arm Body operates as a rigid lever system that rotates or extends between the machine spindle and tool storage. It transfers mechanical force from actuators while maintaining geometric accuracy through precision bearings and alignment features. During operation, it positions the tool gripper with micron-level repeatability, enabling rapid tool changes without manual intervention.
材料
AISI 4140 alloy steel (hardened to 45-50 HRC) or aluminum 7075-T6 for lightweight applications. Surface treatment: Hard chrome plating (0.003-0.005" thickness) or nickel plating for corrosion resistance.
