我厂有几台外圆磨床,由于工件变换,需要经常上、下卡盘。原来,上、下卡盘时,需要两人协作,且易碰坏工作台。现我们设计了一套磨床卡盘的装卸装置,一个人就可装卸卡盘,经过使用,效果良好。卡盘结构见图示。卸卡盘时,先将卡盘中的螺母松开,把丝杆2(梯形螺纹)伸入床头箱主轴孔内,大头直径比主轴孔小2～3毫米。用卡盘1夹紧丝杆大端直径,用梯形螺
I have a few cylindrical grinding machine factory, due to changes in the workpiece, the need for regular upper and lower chuck. The original, the upper and lower chuck, you need two people to collaborate, and easy to damage the workbench. Now we have designed a grinder chuck loading and unloading device, a person can load and unload chuck, after use, the effect is good. Chuck structure shown. When unloading the chuck, first loosen the nut in the chuck, and extend the screw rod 2 (trapezoidal thread) into the spindle head hole of the bedhead box. The diameter of the bulk head is 2 to 3 mm smaller than the diameter of the spindle hole. Use chuck 1 to clamp the large end of the screw diameter, with trapezoidal screw
