四轴卧式钻孔专用机床液压及控制系统设计

摘  要：四轴卧式钻孔专用机床适合成批生产或大量生产，且能钻削具有圆柱形外表面的工件。它特别适合于加工深度直径比大于30，立式加工困难的高粗糙度的小孔径深孔。广泛用于阀门、法兰、轴承座、汽车配件、工程机械配件等生产钻孔加工。在设计过程中，通过各阀之间的联合运作来控制液压缸的运动，并且利用电气开关来控制液压系统，最后通过所设计的液压回路完成液压缸在快进、工进、快退之间的转换。而各阀之间的连接是通过集成块的孔道来实现的，液压泵与集成块连接，使油液通过各集成块里的管道最终到达液压缸。使用集成块可以节约阀的安装空间，减少管件连接，从而降低由于管道接头引起的泄漏问题，而且集成块价格便宜。由此可以看出集成块的设计对于液压系统设计尤为重要。

Design of Hydraulic System for the Four Axis Horizontal Drilling Machine

Abstract: Four axis horizontal drilling machine is suitable for batch production or mass production, and drilling has a cylindrical outer surface of workpieces dedicated machine. It is especially suitable for processing depth to diameter ratio greater than 30, vertical machining difficult high roughness of small diameter deep hole. Widely used in valves, flanges, bearing, auto parts, engineering machinery accessories such as production and drilling processing. In the design process, through the valve between the joint operation to control the motion of hydraulic cylinder, and the use of electrical switches to control hydraulic system, finally through the design of hydraulic circuit for hydraulic cylinder to complete in the fast forward, rewind, feed conversion between. Each valve is connected between the through integrated block channel to implement, hydraulic pump with integrated block is connected, so that the oil through the integrated block in the pipe eventually reach the hydraulic cylinder. The use of integrated block can save valve installation space, reducing pipe connection, thereby reducing the pipeline joint caused by leakage problem and integrated block, cheap price. It can be seen that the IC Design for the hydraulic system design is particularly important.
