基于Solidworks单面多轴组合钻床液压集成块及其加工工艺的设计

卧式单面多轴组合钻床液压系统集成块

及其加工工艺的设计

设计总说明

传统的液压系统是通过油管道连接，对管道所承受的压力要求较高，而且容易造成漏油，影响运动的平稳性，其运动效率低，论文采用液压集成式连接代替传统的液压系统，选择板式液压元件安装在集成块上，将油孔道布置在集成块体内，既缩小了装置的占用面积，同时还消除了漏油现象，提高液压系统的稳定性。

本课题主要针对卧式单面多轴组合钻床液压系统的集成块进行设计，同时借助Solidworks辅助设计，综合应用各种先进的设计理念完成本次课题的研究。

论文第一部分首先根据技术参数，完成液压系统的工况分析，制定出液压系统的各个回路，拟定出液压系统原理；然后确定液压缸的工作压力和主要尺寸；最后根据各工作回路的最大压力和流量选择液压元件，确定出液压元件的型号和尺寸。

第二部分论文对该液压系统集成块结构进行设计。首先绘制集成块单元回路图，再合理的布置液压元件，同时借助Solidworks辅助设计绘制出三维图、二维视图，确定各油孔和连接孔号、孔径与孔深，并根据使用要求确定详细的技术要求。

最后设计集成块的加工工艺。根据集成块的技术要求，毛坯材料选择45号钢，确定出毛坯余量。其次拟定出加工工艺路线，绘制出加工工艺卡片。

本次设计使用板式液压阀，将液压系统集成到几个一定尺寸的集成块上，避免了传统液压系统的弊端。同时使用Solidworks软件设计，将集成块体内的孔道空间位置清楚地展现出来，对实际生产有着一定意义。但是此次设计也有很多地方的不足，例如没有考虑到油液流动的速度对油路弯道的冲击力，和油孔实际加工中的沉孔等工艺孔的设计，希望能够在下次设计中得到更多的改进。

Structure and Process of the Hydraulic Manifold on the Horizontal

Single –sided Multi-axis Combination Drilling Machine

Design Description

The traditional hydraulic system connects through oil pipelines, and has a higher demand for pressure of pipelines. With its easy to lead, unstable and lower efficiency. The design replaces the traditional hydraulic system with integrated system, on which the plate hydraulic components installed and the oil duct arranged in the block, which not only shrinks the device space and eliminates the leakage, but also improves the stability of the hydraulic system.

The project is mainly focused on horizontal single-sided multi-axis combination drilling machine hydraulic system design, and with the help of Solidworks, completes the work application of advanced concepts.

First part: according to the requirements and the parameters, the analysis of working conditions and the schematic diagram of the hydraulic system are proposed in this paper. The pressure and main dimensions of the hydraulic cylinder are determined. At last, the type and the size of hydraulic valves are selected based on the primary hydraulic cylinder pressure and flow calculation.

Second part: the structure of the manifold. The circuit diagram of manifold block unit, a layout of hydraulic components and the dimensions of every oil holes which are shown in the 3D map, 2D view in this paper.

Finally, the manifold processing. According to the technical requirements of the manifold, 45 steel is selected as the blank material. The blank margin, the processing line, the manufacturing processing card are worked out.

The plate hydraulic valves are used in the design to make the hydraulic system integrated into manifold blocks, which can avoid the drawbacks of traditional hydraulic system. With Solidworks software the location of the holes in the manifold block are clearly demonstrated. However, this design also has many disadvantages, for example, the impaction of the oil flow on the block at the oil corner and the sink holes do not take into account, which be improved in the future .
