我厂在实践中采用了新颖适用型快卸螺栓(见附图),它能够较大地缩短零件联接的装配和拆卸时间。简化在操作困难的地方联接零件。装配时,将螺栓组合件穿入被联接件螺栓孔内,以全露出“螺栓颈”为准,将特制垫圈插入“螺栓颈”,旋紧螺母:拆卸时,仅需旋松螺母1～2牙(即轴向移动1.5mm以上),使螺栓2在轴线方向上作移动,直至螺栓头全露出垫圈的鱼眼坑,即可抽出垫圈,使被联接零件分离。由于鱼眼坑,使得螺栓与垫圈在旋紧状态成牢靠联接,不同于一般开口垫圈,即使有振动, I plant in practice using a new type of quick release bolts (see photo), it can greatly reduce the assembly and disassembly time of the connection parts. Simplify coupling parts in difficult operating areas. When assembling, insert the bolt assembly into the bolt hole of the coupler, and expose the “bolt neck” as a whole, then insert the special washer into the “bolt neck” and tighten the nut: When disassembling, just loosen the nuts 1 ~ 2 Teeth (ie, axial movement of 1.5mm or more), so that the bolt 2 in the axial direction of movement until the bolt head washers exposed fisheye pit, you can pull out the gasket, the parts are separated. Due to the fisheye pit, making the bolt and washer in a tight state into a solid connection, unlike the general open washer, even if there is vibration,
