在生产中,经常会遇到一些工件要求加工一组按一定距离均匀分布,而其形状和尺寸又彼此相同的表面,例如:钻、铰一组等分孔,或铣一组等分槽、多面体等,为便于加工,常需回转分度夹具加工上述工件。 传统的回转分度夹具通常是手动分度、对定、锁紧;生产效率低,工人劳动强度大,不利于自动化大生产。因此笔者设计了单片机控制的回转分度夹具。系统结构见图1。 In production, often encountered some workpieces required to process a uniform distribution of a certain distance, and its shape and size and the same surface, for example: drill, hinge a group of equal hole, or milling a group of sub-groove, Polyhedron, etc., in order to facilitate the processing, often need to turn the indexing fixture processing the above workpiece. Traditional rotary indexing fixture is usually manual indexing, fixed, locking; low productivity, labor-intensive workers, is not conducive to automated large-scale production. So I designed a single-chip control rotary indexing fixture. System structure shown in Figure 1.
