为了满足产品工艺要求,进一步解决铝合金件螺纹配合问题,提高产品质量和生产效率,在汽油机生产中,通过我厂工人师傅和部分技术人员的努力,成功地采用了光孔上丝新工艺。光孔上丝就是在孔加工后,不需要攻丝即可直接利用钻床将螺丝(螺栓)配到孔内。这样,可以使工艺简化,并且减少了由于受到丝锥、接杆和机床主轴等一系列问题,所造成的丝孔精度不稳定而影响装配的弊病。 In order to meet the technical requirements of products, aluminum alloy parts to further solve the problem of thread fit to improve product quality and production efficiency in the gasoline engine production, through the efforts of our factory workers and some technical staff, the successful use of a new optical technology on the wire. Optical wire on the hole is processed in the hole, do not need to tap directly to the use of drilling machine screws (bolts) allocated to the hole. In this way, the process can be simplified, and the shortcomings of the assembly due to the instability of the wire hole due to a series of problems caused by the taps, the connecting rods and the spindle of the machine tool are reduced.
