上横梁、活动横梁和工作台是液压机的主要零件,这三大件对主机的精度影响很大。我厂批量生产315tf 液压机,为保证上述三大件的镗孔精度,通用镗床已不能满足需要。为此,我广自行设计制造了一台液压机专用镗孔机床,现介绍如下。一、设计依据及工艺要求活动横梁是主要运动零件之一,四孔为导向孔,工作面面积较大,在1.92m~2上对四孔 On the beams, beams and workstations is the hydraulic machine’s main components, the three major pieces of precision on the host a great influence. I plant mass production 315tf hydraulic machine, in order to ensure the accuracy of the above three pieces of boring, general boring machine has been unable to meet the needs. To this end, I widely design and manufacture of a hydraulic machine boring machine, are described below. First, the design basis and process requirements Activity Beam is one of the main moving parts, four holes for the pilot hole, a larger working area, at 1.92m ~ 2 on the four holes
