图1所示是被加工零件,该件是我厂产品中常见的一种轴套,属小批量生产,形位公差精度要求比较高。为了在普通车床上加工出高质量的合格品,我们设计了如图2所示的油液弹性定心车夹具。油液弹性定心车夹具,是利用弹性元件——薄壁弹簧套受油液压力作用后,产生均匀弹性变形,实现对工件的自动定心夹紧。夹具结构(附图2),工件以内孔为第一定位基准,以左端面为第二定位基准。工件套装在薄壁弹簧套14外圆上,
Figure 1 shows the parts being machined, which is a kind of bushings commonly found in our products. It belongs to the small batch production, and the precision of the form position tolerance is relatively high. In order to produce high-quality qualified products in the ordinary lathe, we designed the oil elastic centering vehicle fixture as shown in Fig.2. Oil elastic centering car fixture, is the use of elastic components - the thin-walled spring sleeve by the hydraulic pressure, the resulting uniform elastic deformation, to achieve automatic centering and clamping of the workpiece. Fixture structure (Figure 2), the workpiece to the hole for the first positioning reference to the left end surface for the second positioning reference. Workpiece set in the thin-walled spring sleeve 14 on the outer circle,
