1、Car chassis process planning processes 汽车底盘工艺规划的流程 应聘人：张 慧 日 期：2013年7月9日 在总装工艺中，底盘工艺设计相对于电器和内外饰来说，刚性强，多品 种车型的通用性差，每更新换代一种车型，均需要更新车间大量专用设备和生 产工艺。底盘工艺设计可以称得上是总装生产线的“灵魂”，涉及的专业知识 较多，如机械化、电控、非标设备、抱具结构等，决定着生产线的工艺设备种 类和数量、物流工位器具形式等。因此，底盘工艺设计在总装生产线的开发中 占有举足轻重的地位，是产生高性价比总装生产线的关键。 综述 In the assembly process,

2、the chassis relative to the electrical and process design for interior and exterior, rigid, multi-species models of the general poor, one model for each replacement, all you need to update a large workshop equipment and production processes. Process design chassis assembly line can be called a soul,

3、 involving the expertise of more, such as mechanization, electronic control, non-standard equipment, hold a structure, determine the production line process equipment types and quantities, logistics station form such appliances. Therefore, the chassis assembly line process design in the development

4、occupies a pivotal position, is to produce cost-effective assembly line key. The first step: Chassis prerequisite for process design 第一步：底盘工艺设计的前提条件 1.1产品资料 将所有数模装配在一起就构成了一个整车数模，从数模中可以获得零部件的结 构尺寸、位置关系。由数模还可以生成整车、分总成，因此工艺设计计过程中，首 先要输入数字模型。 1.1 Product information Assembled together all the digital-an

5、alog constitute a vehicle modulus, modulus can be obtained from several parts of the structure, size, position relationship. Can also be generated by a digital-analog vehicle, sub-assembly, thus taking into account technological design process, we must first enter the digital model. 2.1 plant design

6、 parameters Plant design parameters include the following aspects: a production program that annual production; b is the base year production shifts, production line utilization; c production line automation; d production line process requires (such as major equipment selection principles, means of

7、transportation lines, electrical control levels, etc.); 2.1工厂设计的参数 工厂设计的参数包括以下几方面： a 生产纲领即年产量； b 年时基数即生产班次、生产线的利用率等； c 生产线的自动化程度； d 生产线的工艺水平要求（如主要设备选用原则、生产线的输送方式、电气控制 水平等）； The first step: Chassis prerequisite for process design 第一步：底盘工艺设计的前提条件 Step Two: Process Analysis 第二步：工艺分析 2.1工艺线路分析 根据设计院提供的产

8、品资料进行产品工艺线路分析，完成装底盘工艺线路图 或爆炸图设计。 2.1.1 产品分块 同类型底盘的分块基本相同，一般底盘均由燃油系，动力传动系，转向系，行 驶系以及制动系等组成），各总成之间的连接方式及顺序合理的分块才能保证装配。 2.1 Process Line Analysis According to institute provides product information for product line analysis process to complete wiring diagram mounted chassis technology or explosion draw

9、ing design. 2.1.1 chunked The same type of chassis is basically the same block, generally by the fuel system chassis, power train, steering system, driving system and the braking system and other components), the connection between the assembly and the order of the sub-blocks in order to ensure rati

10、onal assembly。 Step Two: Process Analysis 第二步：工艺分析 2.1.2 SE analysis SE analysis includes the following aspects: a hold with upper body positioning point is universal; b tooling is universal; (mainly including engine spreader, front axle dispensing tooling, etc.) c partially assembled chassis instit

11、utional change is enough space; (wind trigger assembly is interfering with other components, torque wrench torque when playing rotation has enough space, etc.) SE分析主要包括以下方面: a、抱具上车身定位点是否通用； b、工装是否通用；（主要包括发动机吊具、前桥分装工装等） c、底盘机构变化部分装配空间是否足够；（如风扳机装配时是否与其他零部 件干涉、扭力扳手打扭力时转动空间是否足够等） d、装配工装是否与零部件干涉、零部件与零部件是

12、否干涉； e、油液加注量是否变化； f、同一工位的工具是否通用。 g、工位节拍是否平衡（例如解决工位平衡的方法为：分装成小总成、分成 几部分分工位装配） 针对SE检查出的问题，一般形成问题KTM表，进行逐项整改关闭。 Step Two: Process Analysis 第二步：工艺分析 d assembly tooling and parts are interfering, parts and parts for interference; e whether the amount of oil fill change; f the same station of the tools ar

13、e common. g station beat is balanced (for example, a balanced approach to solve stations are: Aliquot into small assembly, divided into several parts division bit assembly) For SE Check out the problem, the general problem of KTM table form for itemized rectification closed. 2.2 工程化阶段 2.2.1 确定装配顺序 底

14、盘上的每个零部件、分总成和总成都是按照严格的顺序进行组装从而 完成整个底盘的装配，每个零件的装配顺序必须保证能完成全部装配工作且 便于装配。 2.2.2 工具选型 根据装配技术条件选择风扳机、套筒、电动扳手等工具 Step Two: Process Analysis 第二步：工艺分析 2.2 Project stage 2.2.1 determine the assembly sequence Each chassis components, sub-assemblies and assemblies are assembled according to a strict order to c
