该厂车工车间使用的C9220AL多刀液压半自动车床的夹紧油缸未改革以前是固定式的。其最大的缺点是漏油现象严重和推力轴承容易损坏,因此他们吸取了济南轴承厂转动式油缸的优点设计了一种平面磨损,自动补偿转动式油压夹紧缸。经使用证明,此种转动式油缸能较好地解决夹紧油缸漏油问题,同时还可延长油缸的使用与维修周期,不足之处是加工及拆卸较固定式油缸麻烦一些。附图1幅。
The factory used car workshop C9220AL multi-tool hydraulic semi-automatic lathe clamping cylinder is not fixed before the reform. Its biggest drawback is the serious oil leakage and thrust bearing damage easily, so they learned the advantages of rotary bearing Jinan Bearing Factory designed a plane wear, automatic compensation rotary hydraulic clamping cylinder. Proved through the use, this rotary cylinder can better solve the problem of oil leakage clamping cylinder, but also extend the use of fuel tanks and maintenance cycle, the downside is the processing and removal of fixed-type cylinder more trouble.
