【摘要】：本课题主要研究内容是驾驶室用油缸缸筒扩径机的设计与研究,解决目前半自动化扩径过程中存在的成本高、效率低、加工质量一致性差等问题。本文根据具体的技术要求,有针对性的解决上述问题,实现由人工到智能化的转变,避免人为因素对加工质量的影响,在保证质量的同时,提高生产效率。本文首先根据技术要求对设备整体进行结构功能划分,将整台设备分为四个部分:上料机构、机械手、扩径机构和卸料架。通过运用机械学科理论知识,对各个子系统的机械结构进行设计,利用Solidworks软件的三维建模功能对各个子系统的三维模型进行构建,并对各子系统的主要零部件进行选型。应用有限元分析软件ANSYS WorkBench(AWB)对扩径机的整体机架以及主要受力部件挡块及推杆进行静力学分析,并对扩径机的简化模型进行模态分析,确保设计的合理性。通过利用三维绘图软件和有限元分析软件对扩径机机械结构的设计,大大缩短了产品设计周期,解决了人工设计效率低、设计时间长等问题。根据扩径机气动系统和液压系统执行元件的运动要求,设计出相应的气动回路与液压回路,并画出气动原理图和液压原理图。综合设备的机械结构特点和功能要求,设计出电控系统方案。本设备选用PLC作为核心逻辑控制器,通过控制软件对扩径机的程序进行编写,实现扩径过程由人工操作到自动化、智能化的转变,解决了液压缸生产企业生产效率低和加工精度差等问题。对扩径孔机进行安装调试与实验研究,主要确定三项需要验证的指标:1.扩径机的生产效率2.加工精度3.设备的过程性能指数。使用扩径机的手动操作模式模拟人工操作与扩径机自动模式进行效率对比,通过实际测得的数据计算出设备的生产节拍并与技术要求进行对比。采集一组扩径后缸筒的内径尺寸,验证其是否满足加工精度的技术要求,并且通过对扩径机的过程性能指数Ppk的计算,证明扩径机加工过程的稳定性及可靠性。
[Abstract]:The main research content of this topic is the design and research of the cylinder diameter expanding machine in the cab oil cylinder, which solves the problems of high cost and low efficiency in the process of semi-automatic diameter expansion at present. According to the specific technical requirements, this paper solves the above problems, realizes the transformation from artificial to intelligent, and avoids the influence of human factors on the processing quality. In order to ensure the quality, improve the production efficiency. Firstly, according to the technical requirements, the whole equipment is divided into four parts: feeding mechanism, manipulator. The mechanical structure of each subsystem is designed by using the theoretical knowledge of mechanical discipline. The 3D model of each subsystem is constructed by using the 3D modeling function of Solidworks software. The main parts of each subsystem are selected and the finite element analysis software ANSYS WorkBench AWB is used. The statics analysis of the integral frame of the expanding machine, the main force components, the block and the push rod is carried out. The simplified model of the expanding machine is analyzed by modal analysis to ensure the rationality of the design. Through the use of three-dimensional drawing software and finite element analysis software to design the mechanical structure of the expanding machine, the product design cycle is greatly shortened. The problems of low efficiency and long design time are solved. According to the movement requirements of pneumatic system and hydraulic system of diameter expander, the corresponding pneumatic and hydraulic circuits are designed. And draw the pneumatic principle diagram and hydraulic principle diagram. The mechanical structure characteristics and functional requirements of the integrated equipment design of the electronic control system. This equipment selected PLC as the core logic controller. The program of the expanding machine is written by the control software, and the process of expanding the diameter is changed from manual operation to automation and intelligence. The problems of low production efficiency and poor machining precision in hydraulic cylinder production enterprises were solved. The installation, debugging and experimental study of the diameter expanding machine were carried out. Three main indicators to be validated were identified:. 1. The production efficiency of the expanding machine 2. Machining accuracy 3. The process performance index of the equipment. The manual operation mode of the expanding machine is used to simulate the manual operation and the automatic mode of the expanding machine is compared with the efficiency of the automatic mode of the expanding machine. Through the actual measured data calculated the production beat of the equipment and compared with the technical requirements. Collect a group of diameter after the cylinder diameter dimensions to verify whether it meets the technical requirements of processing accuracy. By calculating the process performance index (Ppk) of the expanding machine, the stability and reliability of the process are proved.
