常见的齿轮减速箱上盖(图1),在刨削A、B两平面时,由于零件工艺性较差,所以装夹时很费力气,并且不十分安全。我们利用角钢,按需要的长度和宽度焊制两件方框式的支架(图2)。可以首先将方框支架固定在刨床工作台的合理位置,将工件吊放到方框支架上去进行校正。也可以将工件放在地面上,用C形夹头将两个方框支架和齿轮减速箱盖夹压 Common gear reducer cover (Figure 1), planing A, B two plane, due to the poor workmanship of the parts, so when the folder laborious and not very safe. We use angles to weld two square frame brackets to the required length and width (Figure 2). The square bracket can be fixed on the planer table at a reasonable position, the workpiece hanging on the square bracket to be corrected. It is also possible to place the work piece on the ground and clamp the two square brackets and the gearbox cover with a C-clamp
