本文介绍一种用在桑塔纳发动机生产线上的检具,它在实际使用中有很多优点。图1是被检阶梯孔的尺寸,要求检验两个孔深和两个孔径,四项参数分别以①～④标明。虽然尺寸精度要求不高,仅0.1左右,但由于生产批量大,又要求全数检验,因此必须研制一种既具有足够的测量精度,使用又方便的高效专用检具。目前在生产中配备的一台多参数塞规型综合测量装置就满足了上述要求,工件在检具上一次装卡定位后即
This article describes a gage used in Santana engine production line, which has many advantages in actual use. Figure 1 is the size of the inspection ladder hole, requiring inspection of two holes deep and two holes, four parameters were marked ① ~ ④. Although the requirements of dimensional accuracy is not high, only about 0.1, but due to the production volume is large, but also requires full inspection, it is necessary to develop a both with adequate measurement accuracy, easy to use and convenient special gages. Currently equipped with a multi-parameter plug gauge in the production of integrated measurement device to meet the above requirements, the workpiece in the fixture on a card positioning
