在修理机床时,经常碰到由于振动而影响工件的光洁度问题,过去解决这一问题大都凭经验。近两年来,我们用GZ2型测振仪,解决了一些机床修理中的振动问题,取得了较好的效果。举例介绍如下: 532型滚齿机加工最大模数为6,最大直径为630毫米,一般中、小工厂均有这种机床.武汉重型机床厂齿轮车间有6台532型滚齿机,长期带病工作,被加工零件的精度和光洁度都达不到要求。为此,要求该机床大修后,加工出来的齿轮精度达到Ⅰ级,光洁度达到6,且能试切螺旋角为45°的
In the repair of machine tools, often encountered due to vibration and the impact of the finish of the workpiece, the past to solve this problem mostly based on experience. In the past two years, we use the GZ2 vibrometer to solve some vibration problems in the machine repair, and achieved good results. The following is an example: Model 532 gear hobbing machine has a maximum modulus of 6 and a maximum diameter of 630 mm, and is commonly found in small and medium-sized factories. There are 6 sets of 532 hobbing machines in the gear workshop of Wuhan Heavy Duty Machine Tool Factory. The accuracy and finish of machined parts are not up to the requirements. To this end, the requirements of the machine overhaul, the accuracy of the gear processed to level Ⅰ, finish 6, and can test the helix angle of 45 °
