用螺纹环规或塞规检验螺纹,在机器制造中用得很普遍。这是一种手工操作的方法。我厂生产铣床上用的丝杆,因为精度要求不高,所以也用这种方法检验。但是,在检验过程中,一直存在检验效率低、悄耗体力大的问题。在大闹技术革命运动中,我厂出现了许多使手工操作变为机械化的事例,我厂老工人佟福全等人在这些事例的启发下,并学习了苏联经验,利用废料装成一台检验螺纹用的机械化检具。效果良好。检具的结构很简单如附图所示。检具用螺钉固定在平台1上。皮带轮3通过皮带2由平台附近车床上取得旋转运动。这种旋转运动通过伞齿轮4、5或
Thread thread gauge or plug gauge thread inspection, used in machine building is very common. This is a manual method. I plant milling machine used screw, because the accuracy is not demanding, so also use this method of testing. However, in the inspection process, there has always been a problem of low inspection efficiency and heavy labor. In the rush of technological revolution, there were many cases in our factory that turned manual operation into mechanization. Inspired by these examples, our factory worker Tong Fuquan et al. Learned the experience of the Soviet Union and used the waste to test the thread Used mechanized seizure. Good effect. Gage structure is very simple as shown in the figure. Gages with screws fixed on the platform 1. Pulley 3 through the belt 2 from the lathe near the platform to obtain rotational movement. This rotational movement passes the bevel gears 4, 5 or
