近年来在柔性生产系统中,已形成采用可自动更换卡爪的卡盘和卡爪心轴的发展趋势。可整个地更换卡爪,或只更换镶上的卡爪,或更换带可换套的卡爪。图1心轴(发明证书1567331)的卡爪部分由固定块4和可换卡爪1组成,卡爪用止推板7固定在块4上,带弹簧3的夹紧块2通过柄部燕尾形导向槽压向卡爪。用专用机械手更换卡爪,机械手的抓取装置使各卡爪1保持在外圆槽之外。当卡爪1向右移动时,
In recent years, in the flexible production system, the development trend of a chuck and a jaw claw that can automatically replace claws has been formed. The jaws can be changed entirely, or only the jaws inlay can be replaced, or the jaws with changeable sleeves can be replaced. Figure 1 mandrel (Certificate of Invention 1567331) claw part by the fixed block 4 and the exchangeable claws 1, the claw thrust plate 7 is fixed to the block 4, with the spring 3 clamping block 2 through the handle dovetail The guide groove presses against the pawl. The special claws are used to replace the claws. The gripping device of the manipulator keeps each claw 1 outside the outer circular groove. When the pawl 1 is moved to the right,
