机械臂、机器人和模具组件

Abstract

本实用新型提供了一种机械臂、机器人和模具组件，机械臂包括：第一臂体，第一臂体包括第一凹槽；第二臂体，与第一臂体相连，第二臂体包括第二凹槽，第二凹槽的槽壁与第一凹槽的槽壁围合形成容置腔；驱动组件，驱动组件的至少一部分设于容置腔内，也就是说，将机械臂拆分成两个臂体，即将机械臂拆分成两个部分，进行分别制造，能够根据各自整体结构的凸伸部分分别成型，可以消除相关技术中具有中空型腔的机械臂在铸造生产时难以脱模的倒扣结构，有利于模具组件的有效脱模，实现模具组件的复用，有效降低模具组件的制造成本以及机械臂的铸造成本，从而实现铸件的批量生产，进而有利于降低机器人整体的生产成本。
