X50敞车上有一个零件叫角柱(如图1),需要在平面上钻孔。过去是分划线、打洋冲眼及钻孔等工序。这种生产方式不仅劳动量大,而且生产率低、质量又很难保证。经工人们研究后,自制一个简单的翻转式钻模。经实际使用结果,证明操作方便灵活、生产率高、质量好。钻模结构比较简单,主要由钻模板6和櫊架4组成。详细结构如图2所示。根据工件的尺寸大小,在两块扁条料钢板的钻模板6上钻好孔,安装上钻套8,然后与筋板5焊接组成一体。左右櫊架4,分别用角钢与钢板焊成T字形,然后用螺栓12压装在钻床工作台11上。在櫊架4上设有4～5组摆 There is a part on the X50 gondola called a corner post (Figure 1) that requires drilling in the plane. The past is the dividing line, hit the red eye and drilling and other processes. This mode of production not only labor-intensive, but low productivity, quality is difficult to guarantee. After the workers studied, made a simple flip-type drilling. The actual results show that the operation is convenient and flexible, high productivity, good quality. Drill structure is relatively simple, mainly by drilling template 6 and 4 frame. Detailed structure shown in Figure 2. According to the size of the workpiece, drilling holes in the two slab steel plate template 6, the drill sleeve 8 is installed, and then welded together with the ribs 5. Left and right pylons 4, respectively, with angle welded steel plate and T-shaped, and then use the bolts 12 pressed on the drilling table 11. In the frame 4 is provided with 4 to 5 groups of pendulum
