Students' understanding of the transmission route

At this time, it is necessary to use the equipment of the school laboratory to carry out experimental teaching with the help of experimental teachers. Take the CA6140 lathe main drive system and the headstock structure. In the classroom, let the students understand the transmission route through the wall chart, then move the classroom to the laboratory, open the spindle box of the lathe, expose the spindle components, and then start from the beginning. Introduce this part of the transmission route, point out the fixed gears, idler gears, and slip gears that students can't understand in class. Rotate and move these gears separately, let the students thoroughly understand these transmission components, understand their movement laws and the movements in the transmission. effect. At the same time, it is also possible to introduce the spindle structure, the spindle support, the adjustment of the bearing clearance and the structure of the clutch through the physical object, and then return to the classroom to teach the structure of the spindle components, the students can understand the digestive understanding by contacting the physical objects, and naturally do more with less.

Due to the large number of laboratory equipment, except for normal experiments, I can use these equipment for physical teaching when teaching lathes, milling machines, grinding machines and gear hobbing machines. And for those who like to study, you can also open the lab in your spare time to improve their knowledge. Appropriate visits and the use of color stereo charts help the lectures. Because the machine tool introduces the typical commonly used machine tools, it also introduces automatic lathes and combination machines, but these machines are only available in a few factories, for example. Electric meter factory and Songshi factory. In order to enable students to master this part of the content, proper visits are also very necessary. In addition, when introducing each type of machine tool in the machine tool class, in addition to the typical machine tools, other common machine tools in such machine tools are also introduced.
