为了提高批量生产零件的工效和产品质量,我们对C620车床的小刀架结构进行了改进。现介绍如下: 一、基本结构及其工作原理首先拆除上刀架底板中的刀架螺杆、手柄和刻度盘等零件。在刀架底板6与刀架中部8之间安装弹簧9。床鞍上安装偏心轮机构7(见图示,偏心轮机构可进行左右调节),当转动偏心轮机构上的手柄10时,偏心轮就推动上刀架底板运动,从而实现了刀具对工件的切削运动。定位机构4安装在床鞍的前端面。当调节螺钉1把定位机构固定在某一确定位置时,就能有效地控制横向切刀深度。
In order to improve the ergonomics and product quality of mass-produced parts, we improved the small knife holder structure of C620 lathe. Are introduced as follows: First, the basic structure and working principle First removed the knife on the floor turret screw, handle and dial and other parts. A spring 9 is installed between the blade base 6 and the blade center 8. The saddle is equipped with an eccentric mechanism 7 (as shown in the figure, the eccentric mechanism can be adjusted left and right). When the handle 10 on the eccentric mechanism is rotated, the eccentric wheel pushes the upper tool base to move, Cutting movement. The positioning mechanism 4 is mounted on the front face of the saddle. When the adjusting screw 1 fixes the positioning mechanism at a certain position, the depth of the transverse cutter can be effectively controlled.
