滑柱式钻模,在我厂大批量生产CA6140车床的车间,应用已经有十几年了,在使用中很受工人欢迎,夹紧、松开和装卸工件都很方便,提高了生产效率,保证了产品质量。现已列入厂典型夹具设计手册中,结构见图。工作原理:借助于两个导柱10,由手柄8控制齿条轴3升降,从而带动盖模板4升降。工件由圆销7预定位,以定位销6定位,并用三个定位销5压紧工件。
Pillar-type drilling die, in our factory mass-produced CA6140 lathe workshop, application has been more than 10 years, very popular with workers in use, clamping, loosening and loading and unloading of workpieces are very convenient and improve the production efficiency, Ensure product quality. Now included in the factory fixture design manual, the structure shown in Figure. Working principle: With the aid of two guide posts 10, the rack shaft 3 is controlled by the handle 8 to move up and down, so as to drive the cover template 4 to move up and down. The workpiece is pre-positioned by the round pin 7, positioned with the dowel 6, and pressed against the workpiece with the three dowel pins 5.
