我厂自行设计的专用铣床,采用了行星皮带轮进刀机构,这种进刀机构与适当的电器原件配合,可以自动实现快进——工进——快退的工作循环。行星皮带轮进刀机构结构简单、体积小、零件少、制造维修方便、工作可靠、能适用于各种不同的专用设备,特别对农机修造单位的小改小革能起到及时、经济、耐用的作用。结构和原理行星皮带轮进刀机构壳体1(见附图)是一个带双槽的三角皮带轮。它直接安装在工作滑台进刀丝杆3
I designed a special milling machine factory, the use of a planetary pulley into the knife body, this feed mechanism with the appropriate electrical original with the automatic fast forward - work - rewind of the work cycle. Planetary belt pulley feed mechanism has the advantages of simple structure, small volume, few parts, convenient manufacture and maintenance, reliable work, and can be applied to various special equipment. Especially, the small change leather of the agricultural machinery construction unit can play a timely, economical and durable effect. Structure and principle Planetary pulley feed mechanism housing 1 (see photo) is a triangular grooved pulley. It is directly mounted on the work slide infeed screw 3
