戴手套钻削工件易发生事故,不戴手套接触工件有不适之感。为此,我们自制了钻床安全保护装置,现介绍如下: 一、结构原理 钻床安全保护装置结构如图1所示。它由主体1、挂钩架3、限位螺钉6、弹性挂钩7、多节套筒8及调节杆12等 Wear gloves to drill the workpiece prone to accidents, do not wear gloves contact with the workpiece have a sense of discomfort. To this end, we made a self-drilling safety protection device, are described below: First, the structural principle Drilling machine safety protection device structure shown in Figure 1. The utility model is composed of a main body 1, a hooking frame 3, a limit screw 6, an elastic hook 7, a multi-section sleeve 8, an adjusting rod 12 and the like
