【摘要】：汽車散熱器芯體全自動裝配機是目前較為先進的芯體組裝設備,能夠應用于絕大多數(shù)汽車散熱器生產(chǎn)廠家。相較于傳統(tǒng)手動裝配,全自動裝配機在工作效率、裝配質(zhì)量及安全性等方面都有無可比擬的優(yōu)越性,然而目前國內(nèi)市場散熱器芯體組裝自動化程度較低,基本以手工或半自動裝配為主。 本課題以提高汽車散熱器芯體的裝配精度、裝配效率,降低裝配成本,減輕裝配人員的勞動強度為目標,設計制造具有我國自主知識產(chǎn)權的全自動汽車散熱器芯體裝配機。通過研究不同品種規(guī)格的汽車散熱器芯體的裝配工藝,分析現(xiàn)有汽車散熱器芯體的裝配技術,實地考察汽車散熱器芯體的裝配現(xiàn)場,確定了全自動裝配機的動作流程、裝配節(jié)奏、裝配精度等工作參數(shù),在此基礎上完成了全自動裝配機的機構組成和控制系統(tǒng)的設計工作。 本課題采用模塊化設計方法,根據(jù)全自動裝配機的動作流程、裝配節(jié)奏進行總體設計,把全自動裝配機各部分按依據(jù)功能不同分解為三大部、十二大模塊,并逐個進行模塊設計,同時對整機的布局和各模塊之間的連接進行統(tǒng)籌考慮,使各模塊間成為一個有機的整體。利用UG NX軟件建立全自動裝配機的三維數(shù)字化模型,通過較為成熟的虛擬裝配技術,對整機的運轉性能進行模擬運動仿真,對整機驅動氣缸進行選型設計,對壓裝部件中負載最大的伺服電機進行功率和扭矩的核算,對關鍵連接桿件進行結構應力分析,以保證整機的安全性和可靠性。 研制的汽車散熱器芯體裝配機可實現(xiàn)60套／時的散熱器芯體生產(chǎn)效率,所生產(chǎn)的散熱器芯體表面平整度為0.05mm,全自動裝配機裝配位置精度在0.05mm,運行噪聲小于75分貝,可裝配不同型號不同尺寸的散熱器芯體,其裝配側板可調(diào)間距為300-700mm,裝配主片可調(diào)間距為400-800mm,單個芯體可排列鋁管數(shù)25-65。 該設備目前已在江蘇康杰機械股份有限公司試運行,設備運行可靠,穩(wěn)定性、安全性以及生產(chǎn)效率都達到了預期目標。
[Abstract]:Automobile radiator core assembly machine is an advanced assembly equipment, which can be used in most automobile radiator manufacturers. Compared with the traditional manual assembly, the automatic assembly machine has unparalleled advantages in work efficiency, assembly quality and safety. However, at present, the automation degree of assembly of radiator core body in domestic market is relatively low. Basic manual or semi-automatic assembly is the main. In order to improve the assembly accuracy, assembly efficiency, reduce assembly cost and reduce the labor intensity of assembly personnel, the automatic automobile radiator core assembly machine with our own intellectual property rights is designed and manufactured. By studying the assembly technology of automobile radiator core body with different specifications, analyzing the assembly technology of automobile radiator core body, and inspecting the assembly site of automobile radiator core body on the spot, the action flow of automatic assembly machine is determined. On the basis of the working parameters such as assembly rhythm and assembly precision, the mechanism composition and control system of the automatic assembly machine are designed. This subject adopts the modular design method, according to the automatic assembly machine movement flow, the assembly rhythm carries on the overall design, divides each part of the automatic assembly machine according to the function different into three parts, 12 big modules, At the same time, the layout of the whole machine and the connection between the modules are considered as a whole, which makes the modules become an organic whole. The 3D digital model of automatic assembly machine is established by UG NX software. Through the more mature virtual assembly technology, the running performance of the whole machine is simulated, and the type selection of the driving cylinder of the whole machine is designed. In order to ensure the safety and reliability of the whole machine, the power and torque of the servomotor with the largest load in the pressure-mounting parts are calculated, and the structural stress of the key connecting members is analyzed in order to ensure the safety and reliability of the whole machine. The developed assembly machine of automobile radiator core body can realize the production efficiency of 60 sets / h radiator core body. The surface smoothness of the produced radiator core body is 0.05mm, the assembly position precision of the automatic assembly machine is 0.05mm, and the operating noise is less than 75 dB. Different types and sizes of radiator cores can be assembled with adjustable distance of 300-700mm for side plates, 400-800mm for main plates, and 25-65mm for single core. At present, the equipment has been tested in Jiangsu Kang Jie Machinery Co., Ltd. The equipment has been running reliably, stably, safely and efficiently.
