C62型全钢敞车的车体两侧各有六根侧柱。侧柱与边梁的组装是由六个(每边三个)直径20毫米的铆钉铆接而成。国内各车辆修造工厂常用的铆接工艺是:侧柱和土边梁分别钻孔,用螺栓联结固定,再由工人手持风钻铰孔、手工铆接。这样的铆接工艺,工序多、工位多、效率低和劳动强度大。为了适应生产的发展,决定采用多轴钻孔和液压铆接新工艺。我们设计了一种移动式钻
C62 all-steel gondolas on both sides of the body have six side columns. The side columns and side beams are assembled from six rivets of 20 mm diameter (three on each side). The riveting technology commonly used in domestic vehicle construction factories is as follows: the side columns and the soil side beams are respectively drilled and fixed with bolts, and then ream holes are hand drilled by the workers and manually riveted. This riveting process, more processes, more workstations, low efficiency and labor-intensive. In order to adapt to the development of production, decided to adopt multi-axis drilling and hydraulic riveting new technology. We designed a mobile drill
