我厂加工的薄壁缸套,如图1所示。工艺安排在C7620车床上加工“精车外圆及切两端”工序。由于工艺要求定心精度较高,为此,我们设计了外胀式自动定心夹具。
I plant processing thin-walled cylinder, shown in Figure 1. Process scheduling C7620 lathe processing “fine car cylindrical and cut both ends” process. Due to the high centering accuracy required by the process, we have designed an external self-centering jig for expansion.
