适用于工程机械和机动车辆汽、柴油发动机气门组的拆装,通用于国产、进口的顺装式、倒装式配气机构的气门拆装。如附图所示,可调支架采用了外径18mm、内径14mm的细钢管,宽为12cm,长为19cm,中间的调整螺丝和手动顶杆均采用发动机气缸盖外径φ14mm的螺栓,长度分别为15cm、16cm,顶杆手柄φ16mm,与顶杆焊接。顶杆圆形螺母与可调支架焊接在一起。活动夹头用厚15mm的A3号钢板铣制,与可调支架焊接,内装导向块,通过螺丝横向移动,从而改变活动夹头的开口度,以便正确选择锁片直径.
For construction machinery and motor vehicles, diesel engine valve assembly disassembly, common in domestic and imported cis-type, flip valve with the valve body disassembly. As shown in the figure, the adjustable bracket adopts a thin steel tube with an outer diameter of 18 mm and an inner diameter of 14 mm, a width of 12 cm and a length of 19 cm. The middle adjusting screw and the manual plunger both adopt bolts with an outer diameter of φ14 mm of the cylinder head of the engine, 15cm, 16cm, ejector handle φ16mm, and the mandrel welding. Push rod round nut and adjustable bracket welded together. The movable chuck is made of A3 steel plate with a thickness of 15mm and is welded with the adjustable bracket. The guide block is installed inside, and the opening of the movable chuck is changed by the horizontal movement of the screw, so that the diameter of the locking plate can be correctly selected.
