本文介绍的装配机用于在内燃机气缸盖的阀杆上装弹簧、上弹簧座、O形密封圈及锁圈。所有这些动作都是连续的,自动的。过去,O形圈和锁圈都是人工装到阀杆上人的,主要是由于在装配时这些零件的输送、给料和正确就位有困难。同时,上弹簧座在装配完成后是包住锁圈的,所以在装配时必须先把上弹簧座压下去。此外,如果锁圈没有就位,装配好的O形图就有可能被上弹簧座刮坏,所以在锁圈完全装好之前,弹簧必须保持压缩状态,从而使上弹簧座与O形圈保持一定的距离。因此,为了把O形圈和锁圈连续自动地装到气缸盖的阀杆上去,设计了这种装配机。
This article describes the assembly machine for the engine cylinder head stem mounted spring, the upper spring seat, O-ring and lock ring. All these actions are continuous and automatic. In the past, O-rings and locking rings were manually fitted to the stem, primarily due to the difficulty of transporting, feeding and properly seating these parts during assembly. At the same time, the spring seat is wrapped around the lock ring after the assembly is completed, so the spring seat must be pressed down before assembly. In addition, if the locking collar is not in place, the assembled O-diagram may be scratched by the upper spring seat, so the spring must be kept in compression until the locking collar is fully installed, keeping the upper spring seat and O-ring A certain distance Therefore, in order to o-ring and lock ring automatically and continuously attached to the stem of the cylinder head up, designed this assembly machine.
