本文介紹了一种能简化拉力計油缸加工工艺的单精密副結构。文章在对比了单、双精副結构油缸后指出:在无专用加工設备的情况下采用单精副拉力油缸能大大简化加工工艺,从而确保了加工质量,提高了測量精度。文章介紹了单精副油缸設計时,参数选择应考虑的問題及計算方法。文章还对单精付油缸結构上 This article presents a single, precision sub-structure that simplifies the process of creating a rally gauge cylinder. After comparing the single cylinder and double cylinder with secondary structure, the article points out that adopting a single precision auxiliary hydraulic cylinder can greatly simplify the machining process without the special processing equipment, thus ensuring the machining quality and improving the measurement accuracy. This article introduces the design and parameter selection of single-precision sub-cylinder should be considered in the problem and calculation method. The article also pay attention to single-cylinder fuel tank structure
