为了提高生产效率和保证产品质量,我厂在学习兄弟厂先进经验的基础上试制出磨床自行夹紧卡头,并在磨床电气上做了改进,经长时间使用效果较好,现介绍如下: 如图1所示,首先将卡头体4按磨床床头定位尺寸和螺孔紧固尺寸加工出来,与其它零件装配在一起。根据工件直径选用可换卡头7,工件装入带有1:12锥度的可换卡头7内,靠弹簧10的弹力与床尾顶尖顶紧,夹紧工件。床尾顶尖弹簧的弹力一定要大干夹头弹簧10的弹力,否则,当夹头弹
In order to improve production efficiency and ensure product quality, I plant in the study based on the advanced experience of brother factory trial grinding machine self-clamping chuck, and electric grinder made an improvement, after a long time the effect is better, are as follows: As shown in Fig. 1, the chuck body 4 is first machined according to the positioning dimension of the grinding machine head and the fastening size of the screw holes, and is assembled with other parts. According to the diameter of the workpiece can be used to replace the chuck 7, the workpiece into the chuck with 1:12 taper interchangeable chuck 7, by the elastic force of the spring 10 and the top of the bed tail tight, clamping the workpiece. The elasticity of the top of the bed tail spring must be large dry chuck spring 10, otherwise, when the chuck
