该夹具经实际使用证明具有结构紧凑、夹持可靠、对刀方便、定位合理、操作方便等优点,并能满足槽宽对工件轴线的对称度要求。简单介绍如下。一、结构特点该夹具主要由以下零件组装而成:轴类工件的铣槽部位一端搁在前V形搁架7上;另一端搁在后V形搁架5上,后搁架的左侧面是工件轴的轴向定位基准面。左,右压板9、8对称布置,其夹持工件的动作是同步进行的,夹紧力也相等。U形支承架6上的压紧螺钉2和平端压块3用来压紧工件轴的另一端。对刀
The utility model has proved that the utility model has the advantages of compact structure, reliable clamping, convenient knife setting, reasonable positioning, convenient operation and the like, and can meet the requirement of the symmetry of the slot width on the workpiece axis. Brief introduction is as follows. First, the structural features The fixture is mainly assembled from the following parts: one end of the milled parts of the shaft workpiece resting on the front V-shaped shelf 7; the other end resting on the rear V-shaped shelf 5, the left rear rack Face is the axial positioning of the workpiece axis datum. Left and right platen 9,8 symmetrical arrangement, the clamping action of the workpiece is synchronized, the clamping force is also equal. The compression screw 2 on the U-shaped bracket 6 and the flat-end clamp 3 are used to compress the other end of the workpiece shaft. Knife
