12V190型柴油机的12个汽缸盖共计72条螺栓,在大修过程中若采用人工方法拆卸、紧固这些螺栓,工作效率很低;若使用气动扳手则振动较大,冲击作用会损坏螺栓和缸盖,且不能同时紧固螺栓,进而会导致缸盖受力不均衡。我单位维修的柴油机种类较为单一,工作流程相对稳定,缸盖螺栓位置固定不变,适于使用同步紧固机拆装缸盖。经研究决定,根据自身条件进行制作。
12V190 diesel engine 12 cylinder head a total of 72 bolts in the overhaul process if the manual removal, fastening these bolts, the work efficiency is very low; if the use of pneumatic wrench vibration is greater, the impact will damage the bolts and cylinder head , And can not tighten the bolts at the same time, which in turn will result in imbalance of cylinder head force. My unit repair diesel engine is more single species, the work flow is relatively stable, fixed position of the cylinder head bolts, suitable for the use of synchronous fastening machine disassembly cylinder head. After research and decision, according to their own conditions for production.
