我厂一台X50A铣床工作台横向进给丝杠支架(5025025),在右边紧固螺钉的腰形孔处产生断裂,不得不停工检修。因支架系铸坯件,若更换新的,不管外购或自制,都需较长周期,同时又增加维修费用。针对这种情况,我们采用粘接紧固的方法予以修复,具体工艺过程是,将支架右边腰形孔断裂处铣平,在它上面钻好四个M6螺钉孔,另配一块钢板,与支架接合面尺寸相同,厚度比原厚度小0.25mm,在它上面钻 I plant a X50A milling machine table horizontal feed screw holder (5025025), the right side of the screw-shaped hole at the waist fracture, had to stop work overhaul. Due to the support castings, if the replacement of new, regardless of outsourcing or self-made, require a longer period, while increasing maintenance costs. In view of this situation, we use the method of adhesive fastening to be repaired, the specific process is that the right side of the stent fractured waist hole milling, drilling it in the top four M6 screw holes, and the other with a steel plate, and stent The same size joints, the thickness of 0.25mm smaller than the original thickness, drilled in it
