对于硬海绵、软橡胶、塑料等一类有弹性的非金属材料进行车削加工,可用图1所示的夹具装夹后进行内孔加工,用图2所示的夹具进行外圆车削。如图1所示,用三瓜卡盘8夹住夹持体3,把被加工工件毛坯9与压板5对正,并用力将毛坯压入压板上的四个尖钉7内。此时使压板5上导孔旋槽6与主体1上的调整螺钉4对正后顺时针旋转,即能将毛坯压紧。毛坯松紧要适当,太紧了会使被加工出的产品变形过大,太松了又无法夹持住被加工毛坯。调整
For hard sponge, soft rubber, plastic and other types of elastic non-metallic materials for turning, you can use the fixture shown in Figure 1 after the hole machining, using the fixture shown in Figure 2 cylindrical turning. As shown in FIG. 1, the sandwiching body 3 is clamped by a three-guillotine chuck 8, the workpiece blank 9 is aligned with the platen 5, and the blank is forcedly pressed into the four spikes 7 on the platen. At this time, the guide plate screw groove 6 on the platen 5 is aligned with the adjusting screw 4 on the main body 1 to rotate clockwise, that is, the blank can be pressed tightly. Blank tight to be appropriate, too tight will be processed products will be deformed too large, too loose and can not hold the processed blank. Adjustment
