我厂是大型汽车零部件生产厂,拥有五条曲轴生产线,年生产各种型号曲轴达10万根。在生产过程中,需要对曲轴主轴颈中心线到连杆轴颈中心线之间的距离L(一般称中心距)进行检测。通常我厂使用通用量具进行测量,检测效率比较低,浪费时间。随着生产规模的逐步扩大,生产产量的逐年增多,使用通用量具对曲轴中心距L进行检测,已经不能适用生产批量的需要了。为此,我们设计了一种新型的用来检测曲轴中心距L的专用检具。
Our factory is a large auto parts manufacturing plant, with five crankshaft production lines, the annual production of various types of crankshaft up to 100,000. In the production process, you need to check the distance L (generally referred to as the center distance) between the centerline of crankshaft main journal and the centerline of connecting rod journal. Usually I use a common measuring plant for measurement, detection efficiency is relatively low, a waste of time. With the gradual expansion of the scale of production, production increased year by year, the use of universal measuring tools to detect the crankshaft center distance L, can not meet the needs of the production batch. For this reason, we designed a new type of special gage for detecting the center distance L of the crankshaft.
