B20/2A龙门刨床导轨长9米,两导轨跨距1.25米,安装支承共16对,床身刚度较差,找正极不容易。我们在无光学仪器和成套工具的情况下,仅用几只框式水平仪和一副自制过桥能较快的实现找正,使纵向水平不超过0.02毫米,横向水平不超过0.01毫米,这样,就超过了原机床安装的精度要求。找正工艺过程如下: 粗找:将机床放在坚固的地基上,穿好地脚螺栓(螺栓不必压紧)放好所有的垫铁。在较长的时间内及时找匀垫铁,使机床在自然状态下基本处于水平。
B20 / 2A planer guide 9 meters long, two rails span 1.25 meters, a total of 16 pairs of mounting and supporting, bed stiffness is poor, not easy to find positive. In the absence of optical instruments and kits, we can quickly achieve alignment with only a few frame level and a self-made bridge, the vertical level of not more than 0.02 mm, the horizontal level of not more than 0.01 mm, It exceeds the accuracy requirements of the original machine tool installation. Find the process is as follows: Rough find: the machine on a solid foundation, put anchor bolts (bolts do not have to be pressed) put all the horns. In a longer period of time to find a uniform horn, so that the basic state of the machine at a natural level.
