该测量器用来测量9—25毫米孔径,其结构如图所示。在测量前,应根据被测孔径大小,用千分尺校对零位。按下扳机5时,固定测量卡爪2和活动测量卡爪3便收拢,将其插入工件1的油槽内,放开叛机时,卡爪便可靠地同被测工件接触,活动卡爪推动百分表的表头4。根据槽子实际尺寸测量时和校对零位时百分表的读数差,便可确定测量尺寸的值数。该测量器测量精度为0.01毫米。深度可达70毫米,外形尺寸为185×30×120毫米。本量具的结构简单,测量范围广,而且调整迅速,可用来测量凹槽(尤其是窄槽),在加工中
The measuring instrument used to measure 9-25 mm aperture, its structure as shown. Before measuring, should be based on the size of the measured aperture, with a micrometer proofing zero. When the trigger 5 is pressed, the fixed measuring jaws 2 and the movable measuring jaws 3 are closed and inserted into the oil groove of the workpiece 1. When the defending machine is released, the jaws are reliably contacted with the tested workpiece and the movable jaws push Dial indicator 4. The value of the measurement size can be determined based on the difference in readings of the dial indicator when the actual dimensions of the trough are measured and when the zero is collated. The measuring accuracy of the measuring instrument is 0.01 mm. Depth of up to 70 mm, dimensions of 185 × 30 × 120 mm. The measuring device has the advantages of simple structure, wide measuring range and quick adjustment, and can be used for measuring grooves (especially narrow grooves) during processing
