温州市计量所和温州天平仪器二厂研制成功了DAI-A型直径自动测量仪。最近经有关方面测试鉴定,认为该仪器外型美观,精度较高,体积小,测量方便,操作简单,达到了国内先进水平。大家知道,普通车床在加工另件的过程中,要经常停车,对工件进行测量,使其符合加工要求。这样就带来停车测量耽误工时;起动和停车频繁,对机床齿轮磨损历害,降低机床寿命;分厘卡和游标尺等测量工具的刻线很细,容易造成测量误差,甚至使工件报废等问题。因此,车工精力必须高度集中。目前国内虽有感应同步器的使用,但安
Wenzhou metrology institute and Wenzhou balance instrument factory successfully developed DAI-A diameter automatic measuring instrument. The recent test by the parties concerned identified that the appearance of the instrument, high accuracy, small size, easy measurement, simple operation, reached the advanced level. We all know that ordinary lathe in the process of processing the other parts, to frequent parking, the workpiece is measured to meet the processing requirements. This will bring the parking measurement delay working hours; frequent start and stop, wear and tear on the gear wear and tear, reduce machine tool life; Minute card and vernier ruler measurement tools such as fine lines, likely to cause measurement errors, or even scrapped the workpiece problem. Therefore, the latheworker must be highly concentrated. Although the current use of induction synchronizers, but safety
