轴向柱塞泵泵体加工生产线专机及主辅助设备(车基准机床及双头镗床液压系统设计)

摘要

21世纪的今天，社会经济稳步发展，科学技术高速进步，人们对生产效率的追求是越来越高，尤其是在中国这样的制造大国。

在机械加工行业，如果继续沿用普通机床加工各类零件，不但生产效率低，劳动强度大，质量不稳定，且很难实现大批量生产。目前主要采用自动或半自动生产流水线来解决这一系列的问题。轴向柱塞泵泵体是ZB40柱塞泵的关键零件之一。单件，小批量生产沿用普通机床加工，生产效率低，劳动强度大，质量不稳定。想要达到年产量1万台/年，同时要提高生产率、降低劳动强度、保证生产质量就必须得采用专门的生产流水线来实现。

本次设计主要采用液压系统来实现流水线生产加工过程的部份自动化。我这次做的工作是车基准机床及双头镗床液压系统设计。从整个零件的加工过程来看，基准的精确度直接影响着以后工序的加工过程精度，即在加工过和中基准的精度得要非常的重视。本设计过程要镗的孔在装配中起着重要的作用，如果加工过程中镗孔的精度不能达到精度要求，那么就可能出现不能装配或是装配后不能正常使用，即成为废品。因此，因此在本次设计过程中，我采用液压系统来解决普通机床加工的不足。

Abstract

In the 21st century, with the steady development of our socio-economy and rapid advance of scientific and technological, people pursuit of efficiency of production become more and more urgent, especially in China, which is a big manufacturing country.

In the mechanical processing industry, if we continue to use ordinary machine tool to process various components, it will results in low production efficiency, labor intensity and unsteady quality, which is very difficult to achieve mass production. At present, we mainly use the automatic or semi-automatic production lines to solve those issues. Axial piston pump Body Pump is ZB40 one of the key components. Single pieces and small batch production by using ordinary machine processing result in low productivity, labor intensity and quality instability. Try to achieve annual output of 10,000 units/ year, we should increase productivity, reduce labor intensity and assure quality in a new producing line.

This design focuses on hydraulic pipeline systems, which is used to achieve the production process of automation. My work on this design is to design the standard of lathing and the headed benchmark boring machine hydraulic system. From the entire parts of the machining process, the benchmark precision direct impact on the future operations of the processing accuracy, so the accuracy of the benchmarks needs to be very seriously. The design process should be boring holes in the assembly plays an important role. If processing Boring not achieve the accuracy and precision, it is possible that no assembly or assembly after normal use, that is to say the products will become as scrap. Therefore, in this design, I mainly use hydraulic system to solve those deficiencies of ordinary Machining.
