我厂在y3150滚齿机总装检验工作精度时,当发现精度超差都需拆下蜗杆重新调整其轴向间隙及窜动。由于该产品的批量较大,按此办法去做工作量较大,生产效率低,所以,我们经过几种方案试验后,选定了本文所述的用弹簧力模拟工作实际载荷,在装配工序中把蜗杆间隙、窜动调整至最佳状态的方法。具体如下(见下图): 将蜗杆托架组件7固定于组合夹具的基 I plant assembly work in the y3150 hobbing machine assembly work accuracy, when found to exceed the precision tolerance need to remove the worm to re-adjust its axial clearance and movement. Due to the large volume of the product, according to this approach to do a large amount of work, low production efficiency, therefore, after several programs we tested, selected the spring load simulation described in this article the actual load, the assembly process In the worm gap, play to adjust to the best way. The details are as follows (see below): Fix the worm bracket assembly 7 to the base of the combination fixture
