The first step: Chassis prerequisite for process design 第一:底盘工艺设计的前提条件
1.1 Product information
Assembled together all the digital-analog 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 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 transportation lines, electrical control levels, etc.);
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 complete the entire chassis assembly, each part of the assembly must be guaranteed in order to complete all the assembly work and easy to assemble. 2.2.2 Tool Selection Choose according to wind conditions trigger assembly technology, sleeves, electric wrenches and other tools
2.2.3 tooling design and fabrication According to models of specific institutions, combing complete breakdown of special tooling, design and development of special tooling. 2.2.4 The preparation process of order cards The availability of preconditions, through process analysis, you can begin the preparation process card chassis. Process card chassis design, manufacture and commissioning of the entire process guidance document is the basis for all the work chassis line, the compilation process card on the chassis line depth and quality of the design, manufacture, testing the quality of the whole process even play a decisive role in the success or failure
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 institutional change is enough space; (wind trigger assembly is interfering with other components, torque wrench torque when playing rotation has enough space, etc.)

综述
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。
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。
The first step: Chassis prerequisite for process design 第一步:底盘工艺设计的前提条件
In the assembly process, 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, 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 occupies a pivotal position, is to produce cost-effective assembly line key.
d、装配工装是否与零部件干涉、零部件与零部件是否干涉; 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
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 drawing 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 rational assembly。
