在半自动机床上进行加工时,使用此夹头,可达到一次装夹同时进行工件三个面(工件的两端面及外圆柱表面)的粗、精加工。该夹头的主体14用螺栓固定在机床主轴上,支承工作12的托架13用螺栓固定在主体14上。为防止转动,托架上装有键快;在托架的槽内装有在斛楔9上移动的卡脚11。轮叉6用螺丝旋在斜楔9上,在托叉6的孔内装有系秆5;通过系杆的圆孔的销轴4摧压轮叉6,使之与车床的汽缸3连结。弹簧2作用在
When machining on a semi-automatic machine, the chuck can be used to achieve the rough finishing of three workpieces (the two end surfaces of the workpieces and the outer cylindrical surface) at one time. The main body 14 of the chuck is bolted to the main shaft of the machine tool, and the bracket 13 supporting the work 12 is bolted to the main body 14. In order to prevent the rotation, the bracket is provided with a quick key; the groove of the bracket is provided with a clamping leg 11 which moves on the wedge 9. The fork 6 is screwed on the wedge 9 with a stem 5 in the hole of the fork 6; the fork 6 is pressed by the pin 4 of the tie rod of the tie rod to be connected with the cylinder 3 of the lathe.
