制造医疗器具时,用带有毛毡打光轮的电动机床上的手工抛光,工作量很大,而且灰尘多,制品受振动和产生燥声。最近研制一种在加工区改善通风条件的带式抛光机床,其使用与维护方便。机床(见图)由机架9、主轴部件12、拉紧装置11、拉紧辊7、重物13和固定装置10组成。安装在接触轮和拉紧辊上的研磨带与工作过程中拉紧情况无关,它有固定的拉紧力,这是由于可动的主轴部件和重物的作用而保证的。更换研磨带时只需使手柄5相对铰链8转动,使拉紧装置的可动部分转动至固
In the manufacture of medical devices, manual polishing on a motorized bed with a felt-lit wheel is labor intensive and dusty, and the product is subject to vibrations and dry noise. Recently developed a belt polishing machine in the processing area to improve the ventilation conditions, its easy to use and maintain. The machine tool (see the figure) consists of a gantry 9, a spindle part 12, a tensioning device 11, a tensioning roller 7, a weight 13 and a fixing device 10. The abrasive tape mounted on the contact roller and take-up roller has no effect on the tensioning during the working process. It has a fixed tensioning force due to the action of the movable spindle part and the weight. When changing the grinding belt, only the handle 5 needs to be rotated relative to the hinge 8, so that the movable part of the tensioning device is rotated to the solid position
