一、治理漏油M7120A平面磨床工作台油压筒两端封油结构如图1所示。常见的漏油多数是由于活塞杆3和油封1不断摩擦,形成间隙。当工作台4向右运动时,渗漏出来的油便沿着活塞杆滴下,既浪费油,又影响周围环境清洁。针对这个漏油问题,我们采取了改进措施,具体如下:在法兰盘2上加装一个毛毡油封5,并在法兰盘上钻φ4孔漏油。用凿子把放毛毡的沉割槽下部和漏油孔凿通,这样,油毛毡刮下的油便自然漏入床身油池。这个小改革工作量不大,对原机床外观无影响,但效果却很好。二、改善磨头润滑目前生产出厂的M7120A磨床主轴滑动轴承已采 First, the management of oil spill M7120A surface grinder oil pressure on both ends of the oil cylinder structure shown in Figure 1. Most of the common oil leakage is due to the continuous friction rod 3 and seal 1, forming a gap. When the workbench 4 moves to the right, the leaking oil drips along the piston rod, which is a waste of oil and affects the surrounding environment. In response to this oil spill problem, we have taken remedial measures as follows: Install a felt seal 5 on flange 2 and drill a hole of φ4 on the flange. Use a chisel to put the lower part of the undercut of the blanket and the oil drain hole to dig through, so that the oil scraped by the felt will naturally leak into the bed oil pool. This small reform workload is small, no effect on the appearance of the original machine, but the effect is very good. Second, to improve the grinding head lubrication At present, the M7120A grinding machine spindle bearings have been taken
