一般车床用的卡箍都是两点吃力,并受到一定尺寸范围的限制,往往加工一根轴时,需要换上几个卡箍才能解决问题。我们在实践中革新了一个可调式卡箍,它的结构如附图所示,卡持工件时是三点吃力,同时可以卡持φ5～φ60毫米的轴,减少了更换的时间,使用起来很方便。 General lathe clamps are two difficult, and limited by a certain size range, often when processing a shaft, you need to change a few clips to solve the problem. In practice, we have revolutionized an adjustable clamp. Its structure is shown in the attached figure. It takes three hits when clamping the workpiece, and can hold φ5 ~ φ60 mm shafts, reducing the time for replacement. Convenience.
