多年来,我国工矿建筑施工企业使用的大量台式钻床中,绝大多数的电动机皮带轮和传动皮带均裸露在外,不符合机械安全防护的有关规定。现介绍一种操作简便、安全可靠的全封闭台式钻床安全防护装置。结构型式见图1。罩壳通过螺栓固定在上连接板上,上连接板空套在销轴上,开口销将销轴和手柄连接成为一体,销轴在导管的空腔内可做一定范围的转动和轴向移动,将导管与下连接板焊接在一起,并通过下连接板将整个安全防护装置固定在台式钻床的主轴箱体上面。另外,为了防止罩 Over the years, most of the large number of bench drilling machines used by China’s industrial and mining construction companies have exposed the majority of motor pulleys and drive belts, and are not in compliance with the relevant regulations for mechanical safety protection. A fully enclosed bench-top drilling machine safety protection device with simple operation, safety and reliability is introduced. The structure type is shown in Figure 1. The shell is fixed on the upper connecting plate by bolts. The upper connecting plate is sleeved on the pin shaft. The open pin connects the pin shaft and the handle into one body. The pin shaft can make a certain range of rotation and axial movement in the cavity of the catheter. , Weld the conduit together with the lower connecting plate, and fix the entire safety guard on the spindle box of the bench drilling machine through the lower connecting plate. In addition, in order to prevent the hood
