【摘要】：汽车散热器芯体全自动装配机是目前较为先进的芯体组装设备,能够应用于绝大多数汽车散热器生产厂家。相较于传统手动装配,全自动装配机在工作效率、装配质量及安全性等方面都有无可比拟的优越性,然而目前国内市场散热器芯体组装自动化程度较低,基本以手工或半自动装配为主。本课题以提高汽车散热器芯体的装配精度、装配效率,降低装配成本,减轻装配人员的劳动强度为目标,设计制造具有我国自主知识产权的全自动汽车散热器芯体装配机。通过研究不同品种规格的汽车散热器芯体的装配工艺,分析现有汽车散热器芯体的装配技术,实地考察汽车散热器芯体的装配现场,确定了全自动装配机的动作流程、装配节奏、装配精度等工作参数,在此基础上完成了全自动装配机的机构组成和控制系统的设计工作。本课题采用模块化设计方法,根据全自动装配机的动作流程、装配节奏进行总体设计,把全自动装配机各部分按依据功能不同分解为三大部、十二大模块,并逐个进行模块设计,同时对整机的布局和各模块之间的连接进行统筹考虑,使各模块间成为一个有机的整体。利用UG NX软件建立全自动装配机的三维数字化模型,通过较为成熟的虚拟装配技术,对整机的运转性能进行模拟运动仿真,对整机驱动气缸进行选型设计,对压装部件中负载最大的伺服电机进行功率和扭矩的核算,对关键连接杆件进行结构应力分析,以保证整机的安全性和可靠性。研制的汽车散热器芯体装配机可实现60套／时的散热器芯体生产效率,所生产的散热器芯体表面平整度为0.05mm,全自动装配机装配位置精度在0.05mm,运行噪声小于75分贝,可装配不同型号不同尺寸的散热器芯体,其装配侧板可调间距为300-700mm,装配主片可调间距为400-800mm,单个芯体可排列铝管数25-65。该设备目前已在江苏康杰机械股份有限公司试运行,设备运行可靠,稳定性、安全性以及生产效率都达到了预期目标。
[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.
