我单位从俄罗斯进口一批电动轮自卸车,使用过程中,这些自卸车前轮制动盘沿外圆周均匀分布的6个凸起固定块常出现折断现象。由于该配件价格昂贵,采购周期长,为保证生产正常进行,决定采用焊修方法予以修复。修复方案如下:先在原固定块位置铣槽,然后将6个固定块进行定位和焊接,最后加工至原尺寸。如附图所示。 My unit imports a number of electric wheel dump trucks from Russia. During the process of use, the six raised fixed blocks, which are uniformly distributed along the outer circumference of the front wheel brake discs of these dump trucks, often break down. As the parts are expensive, long procurement cycle, in order to ensure the normal production, decided to use welding repair method to be repaired. Repair program is as follows: first slot in the original slot milling slot, and then six fixed block positioning and welding, and finally processed to the original size. As shown in the figure.
