摘要
三爪卡盘是机床上用来夹紧工件的机械装置,其利用均布在卡盘体上的活动卡爪的径向移动,对工件进行夹紧和定位。但是在对联轴器装夹和加工时,由于联轴器的轴孔加工精度要高于外圆面的加工精度,因此采用三爪卡盘对联轴器的外圆面进行装夹不利于联轴器的高精度加工。为提高联轴器加工精度,提供一种结构简单、操作方便的联轴器加工用三爪卡盘,能够将联轴器稳定、精确的进行定位和固定,从而保证加工产品具有较高的加工精度。
The three-jaw chuck is a mechanical device for clamping the work-piece on the machine tool. It uses the radial movement of the movable claw distributed on the chuck body to clamp and locate the workpiece. However, when the clamping and machining the coupler, because the required accuracy of the coupling holes is higher than that of the cylindrical surface, it is not conducive to the high precision machining of the coupling by using the three-jaw chuck to clamp the outer surface of the coupling. In order to improve the machining accuracy of the coupling, a three-jaw chuck for coupling machining has been provided,which is simple in structure and easy to operate. It can locate and fix the coupling in a stable and precise way, so as to ensure the high accuracy of product.
