【摘要】：本課題主要研究內(nèi)容是駕駛室用油缸缸筒擴徑機的設(shè)計與研究,解決目前半自動化擴徑過程中存在的成本高、效率低、加工質(zhì)量一致性差等問題。本文根據(jù)具體的技術(shù)要求,有針對性的解決上述問題,實現(xiàn)由人工到智能化的轉(zhuǎn)變,避免人為因素對加工質(zhì)量的影響,在保證質(zhì)量的同時,提高生產(chǎn)效率。本文首先根據(jù)技術(shù)要求對設(shè)備整體進行結(jié)構(gòu)功能劃分,將整臺設(shè)備分為四個部分:上料機構(gòu)、機械手、擴徑機構(gòu)和卸料架。通過運用機械學(xué)科理論知識,對各個子系統(tǒng)的機械結(jié)構(gòu)進行設(shè)計,利用Solidworks軟件的三維建模功能對各個子系統(tǒng)的三維模型進行構(gòu)建,并對各子系統(tǒng)的主要零部件進行選型。應(yīng)用有限元分析軟件ANSYS WorkBench(AWB)對擴徑機的整體機架以及主要受力部件擋塊及推桿進行靜力學(xué)分析,并對擴徑機的簡化模型進行模態(tài)分析,確保設(shè)計的合理性。通過利用三維繪圖軟件和有限元分析軟件對擴徑機機械結(jié)構(gòu)的設(shè)計,大大縮短了產(chǎn)品設(shè)計周期,解決了人工設(shè)計效率低、設(shè)計時間長等問題。根據(jù)擴徑機氣動系統(tǒng)和液壓系統(tǒng)執(zhí)行元件的運動要求,設(shè)計出相應(yīng)的氣動回路與液壓回路,并畫出氣動原理圖和液壓原理圖。綜合設(shè)備的機械結(jié)構(gòu)特點和功能要求,設(shè)計出電控系統(tǒng)方案。本設(shè)備選用PLC作為核心邏輯控制器,通過控制軟件對擴徑機的程序進行編寫,實現(xiàn)擴徑過程由人工操作到自動化、智能化的轉(zhuǎn)變,解決了液壓缸生產(chǎn)企業(yè)生產(chǎn)效率低和加工精度差等問題。對擴徑孔機進行安裝調(diào)試與實驗研究,主要確定三項需要驗證的指標:1.擴徑機的生產(chǎn)效率2.加工精度3.設(shè)備的過程性能指數(shù)。使用擴徑機的手動操作模式模擬人工操作與擴徑機自動模式進行效率對比,通過實際測得的數(shù)據(jù)計算出設(shè)備的生產(chǎn)節(jié)拍并與技術(shù)要求進行對比。采集一組擴徑后缸筒的內(nèi)徑尺寸,驗證其是否滿足加工精度的技術(shù)要求,并且通過對擴徑機的過程性能指數(shù)Ppk的計算,證明擴徑機加工過程的穩(wěn)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.
