我们在X5430A升降台式铣镗床上增加一套机械仿形机构,实现了对较大尺寸模具型腔特形曲面的加工(图1)。仿形机构如图2所示。改装时,取下X5430A铣镗床手轮利用接长轴2的一端装上齿轮5,另一端装上轴承3支承在外壳1上。空套在接长轴2上的齿轮5与齿条套筒6啮合,这对齿轮齿条副的参数与机床铣头内齿轮轴和主轴上齿条的参数一致。
We have added a set of mechanical profiling mechanism to the X5430A bench-top milling and boring machine, which has enabled the machining of larger-sized mold cavity profiles (Figure 1). Copying mechanism shown in Figure 2. When retrofitting, remove the X5430A milling boring machine handwheel with a long shaft 2 mounted on one end of the gear 5, the other end fitted bearing 3 supported on the housing 1. The gear 5 engaged with the long shaft 2 is meshed with the rack sleeve 6, and the parameters of the pair of rack and pinion are consistent with the parameters of the gear rack and the rack on the spindle of the machine tool milling head.
