在滚压螺纹过程中,常见的故障通常是指滚丝机产生故障,滚丝轮产生缺陷,被滚压螺纹主要参数的精度超差,表面加工质量不符合规定,以及其它一些异常现象。一、滚丝机产生的故障当滚丝机处于工作状态时,主轴部件、进给机构、压力调整系统、延时机构、油泵、行星齿轮机构等均会出现故障,从而影响机床的正常工作。 1、主轴部件 (1)主轴向外窜动(延伸)。主要原因有:主轴顶端弹簧失效;或压弹簧的螺母松动;或超负荷工作。 (2)主轴旋转时松动过大。一般是由于蜗轮、蜗
In the rolling process, the common faults usually refers to the rolling machine failure, rolling wheel defects, the accuracy of the main parameters of the rolling thread tolerance, surface quality does not meet the requirements, and other abnormalities. First, the rolling machine failure When the rolling machine is in working condition, the spindle components, feed mechanism, pressure adjustment system, delay mechanism, oil pump, planetary gear mechanism, etc. will fail, thus affecting the normal operation of the machine. 1, the main shaft components (1) spindle outward (extension). The main reasons are: the top of the spindle spring failure; or pressure spring nut loose; or overload work. (2) Loose spindle when rotating too much. Generally due to the worm, worm
