豫西机床厂生产的CB3232型转塔车床,其转塔进给油缸与床身接通的油路接头结构见图1。这种结构,在修理进给油缸重新安装时,稍有不慎,就会使O形密封圈破损或移位,造成密封不严,出现液压油的泄漏。为此,我们对CB3232型转塔车床的液压接头结构进行了改进,即在原基础上加一内环(见图2)后,O形密封圈就能稳定。在安装时就不再出现破损或移位,从而解决了液压油的泄漏问题。
West Machine Tool Plant production CB3232 turret lathe, the turret feed cylinder and bed connected to the oil joint structure shown in Figure 1. This structure, the repair feed cylinder re-install, a little careless, it will make O-ring damaged or displaced, resulting in tight seal, the emergence of hydraulic oil leaks. For this reason, we have improved the structure of the hydraulic joint of CB3232 turret lathe, that is, the O-ring can be stabilized after adding an inner ring (see Fig. 2) on the original basis. No longer appear damaged or displaced during installation, thus solving the hydraulic oil leakage problem.
