The anti pinch device of machine tool protective door, which is characterized in that: the structure in the main shell, the rod from the supporting seat body right into the hole, the axial positioning nut and the supporting seat assembly component right contact positioning; the supporting seat on the left side and right end face contact spring contact spring, left end surface and the main casing inside the main shell on the left side of the left side; and the positioning nut, the nut is screwed to the positioning of the positioning effect of the front end of the rod thread; the main support thread assembling components mounted to the machine door pneumatic door at the top of the main housing; welding a shaking cylinder, no contact switch and sway column on the same line, in the distance. The anti clamping device moves with the pneumatic door, and when the pneumatic door is obstructed, the spring is moved backward by the compression force. The cylinder is sloshing without contact switch, and feedback a signal command to change the direction of the valve to drive the cylinder back and open the pneumatic door. In this way, the operator can be avoided because of the rigid closure of the pneumatic door, and the flexible closure can be produced, and the safety of the pneumatic door can be ensured.

机床防护门防夹装置
本技术涉及机械设备,是一种机床防护门防夹装置,安装在机床外防护气动拉门上,对机床加工者进行安全保护。
技术介绍
机床外防护的气动拉门是用来分隔加工区与操作者操作区的部件。气动拉门由气缸作为气动执行元件,来完成机床外防护气动拉门的开关,但由于气缸只能刚性执行前进和后退命令,很容易因操作者误操作造成气动拉门误关闭而造成对操作者的损伤。因此本专利技术就是为了避免操作者在误操作下对人身的伤害。
技术实现思路
本技术的目的是提供一种机床防护门防夹装置,在气动拉门关闭时产生缓冲防夹紧,避免刚性关闭,避免操作者因误操作造成气动门对操作者的伤害。本技术的机床防护门防夹装置,包括支撑座合装组件、气缸,气缸杆驱动主壳体,其特征在于结构:在主壳体内,杆从支撑座体内孔右端穿入,杆右边由轴向定位螺母与支撑座合装组件右面接触定位;支撑座体左侧与圆柱螺旋压缩弹簧右侧端面接触,圆柱螺旋压缩弹簧左侧端面与主壳体内左侧接触;主壳体外左边和定位螺母接触,定位螺母拧到杆前端螺纹上起到定位作用;主体支撑支架螺纹连接合装组件后安装到机床防护气动拉门顶部;主壳体下焊接一个晃动柱体,无触点开关与 ...
