装配带有O型密封圈的轴类零件,通常需将孔的端部倒角,以利于导向。由于密封槽深尺寸、密封圈的厚度及孔径均有偏差,加上堵头件往往短而配合较紧,因而装配效率低、费力,且质量也不够理想。如图1所示的薄壁套件连螺纹在内仅2毫米厚,内孔倒角已无多少余地,装配时密封圈经常被切断,密封失效。我们做了一个简单的工装(图2),可以不用在孔口倒角而保证其装配质量,且速度快、省力。

Assembly of shaft parts with O-rings usually requires chamfering the end of the hole for guidance. Due to the deep seal groove size, the thickness of the seal ring and the aperture are biased, coupled with the plug pieces are often short and with tight, so the assembly efficiency is low, laborious, and the quality is not satisfactory. As shown in Figure 1 thin-walled kit even within the thread only 2 mm thick, the chamfer hole has no room for the assembly of the ring is often cut off, the seal failure. We made a simple tooling (Figure 2), you can not chamfer the orifice to ensure its assembly quality, and fast, labor-saving.
