我厂在河北-30型拖拉机的技术改造中,制造了一批组合机床流水线。为了提高机床的机械化、自动化程度,对一些技术要求较高的机床采用了液压传动技术。 机床液压装置中液压元件的安装和连接,一般以管式连接和板式连接比较普遍,但这两种连接方式都有其一定缺点。管式连接用输油管将液压元件、执行机构连接起来,这样很多油管上下交叉,纵横交错,给制造和维修带来
In the technical transformation of Hebei-30 tractors, our factory produced a number of combined machine tool lines. In order to improve the degree of mechanization and automation of machine tools, hydraulic transmission technology has been adopted for some machine tools with higher technical requirements. The installation and connection of the hydraulic components in the machine hydraulic unit is generally common with pipe and plate connections. However, these two connection methods have certain disadvantages. The tubular connection connects the hydraulic components and the actuators together with the oil pipeline so that many pipelines cross over and down in a crisscross pattern, bringing manufacturing and maintenance
