设计总说明

本课题来源于社会实际生产，这次课题给定零件为汽车转向器壳体。转向器是汽车行驶系统中的重要安全部件，其质量好坏对汽车直线行驶的稳定性和操纵稳定性都有直接影响。汽车在行驶过程中需要改变行驶方向时，驾驶员通过汽车转向系使汽车转向桥，一般是前桥，上的车轮相对于汽车纵轴线偏转一定的角度，使汽车达到转向目的。另外，当汽车在直线行驶时，转向轮往往会受到路面侧向干扰力的作用而自动偏转的，从而改变了原来行驶方向，此时，驾驶员也可以通过汽车转向系使转向轮向相反的方向偏转，恢复了汽车原来的行驶方向。

本次设计主要任务是按照给定零件设计其加工自动线，随行夹具输送，完成自动线总体设计、专用设备机械结构设计、主要零件设计。具体有：

1．拟定全线自动化方案，确定总体布局；

2．专用设备方案分析及方案设计；

3．专用设备总体设计（布局、主要参数、运动方案和原理、控制方案）；

4．专用设备机械结构装配设计；

5．主要零部件结构设计。

本设计先从汽车转向器壳体的零件图入手，通过实际情况的调查研究和查阅相关资料，了解其功用、种类以及国内外发展状况、发展水平及存在问题等，写出开题报告，拟定进度表等。然后，就按照进度表完成各阶段的设计内容，最终完成本设计。

本设计的基本设计流程如下：

1.分析零件结构。

2.分析毛坯情况。

3.分析年产纲领是否合乎建立生产线条件。

4.拟定工艺方案，并绘制工序图和加工示意图。

5.拟定全线的自动化方案。

6.确定自动线的总体布局，绘出自动线的总联系尺寸图。

7.随行夹具的设计。

INTRODUCTION

This topic comes from the actual production of the society, the topic given parts for automotive steering gear housing. Steering gear is a system of the most important components of the vehicle running, the quality of the car is moving in a straight line stability and handling stability has direct impact. Car in the driving process needs to change direction of travel, the driver through the car steering system the steering axle of automobile, front axle, wheel relative to the vehicle longitudinal axis deflection angle, making the car reach the purpose of steering. Also when the car in a straight line driving, steering wheel tends to be influenced by the role of pavement lateral disturbance force and automatic deflection, thus changing the original direction of travel. At this point, the driver can also through the automotive steering system the steering wheel to the deflection in the opposite direction, to restore the automobile to the direction of travel.

The design of the main task is to design the automatic production line according to a given part, pallet conveyor, complete the general design of the automatic line, special equipment for mechanical structure design, design of the main parts. Concrete:

1 to develop a full line automation plan, determine the overall layout;

2 Scheme Analysis and scheme design for special equipment;

3 special equipment (overall design layout, main parameters, motion principle and scheme, the control scheme);

4 the mechanical structure of special equipment;

5 main parts structure design.

The design of the first from the automobile steering device casing parts diagram of through the actual situation of the research and access to relevant information to understand its function, as well as the type of development situation at home and abroad, the development level and the existence question and so on, write a proposal, develop schedule etc.. Then, in accordance with the schedule to complete the design content of each stage, the final completion of the design.

The basic design flow of this design is as follows:

1 Analysis of parts structure.

2 Analysis of rough case.

3 analyze whether the annual program meets the establishment of production line conditions.

4 develop and process scheme, process drawing and processing sketch map.

5 to develop automated programs across the board.

6 to determine the overall layout of the automatic line, the total contact size diagram drawn line.

7 design of accompanying fixture.
