一般的机械加工行业中,游标卡尺是使用频率最高的量具,磨损与损坏也很频繁,其检定和修理相辅相成。对于检定,有国家检定规程,但对于修理,由于没有统一的标准,因此,不同的修理人员相互有一定的差距。针对游标卡尺使用中容易出现的尺身基面磨损不匀、测量面张口;上、下量爪示值不一致;测量面间隙不稳定等缺陷,给卡尺带来的示值误差,根据多年的经验整理,下面主要简述和介绍几种常见缺陷的修理方法,以供参考: 1.量爪合拢时测量面无间隙,检定示值误差时,外量爪示值较好,内量爪(刀口型)示值明显超差,而且是正值
In general machining industry, vernier caliper is the most frequently used measuring tool, wear and damage are also frequent, and its verification and repair complement each other. For the test, a national test procedures, but for the repair, because there is no uniform standard, therefore, different repair workers have a certain gap between each other. In view of the use of vernier caliper easy to appear on the ruler base surface uneven wear, measuring surface mouth mouth; upper and lower claw inconsistency shows inconsistencies; measuring surface gap instability and other defects to the caliper to bring indication error, based on years of experience , The following is a brief description and introduction of several common defect repair methods for reference: 1. When the measuring jaw closed measuring surface without clearance, check the indication error, the external jaw shows better value, the amount of claw ) Indications were significantly overbought, and positive
