我们在为加工(钻孔)五铧犁四种主梁而设计的组合机床上采用了一种气动“浮游”双向夹具。 由于被加工主梁长在3米以上,如只采用单向(由上向下)夹紧,由于主梁有不直度偏差,钻削时将会产生孔位误差,影响质量。为此,在横向也要夹紧。同时,为了减少气缸和气动元件的用量,而采用了这 We have adopted a pneumatic “floating” bi-directional clamp on a combined machine designed for machining (drilling) five plows of four main beams. As the length of main beam to be machined is more than 3 meters, if only one way (from top to bottom) is used for clamping, due to the deviation of the main beam, the hole position error will occur during drilling, which will affect the quality. To do this, we must also clamp in the horizontal direction. At the same time, this is used to reduce the amount of air cylinders and pneumatic components
