黑龙江工程学院本科生毕业设计 I 摘 要 微型及普及型汽车在我国有很大市场，从 0.9L 到 1.6L，价格适合我国国情，适合正在发展的中国的现况。发动机是汽车重要零件之一，随着现在设计加工制造技术的发展，发动机的装配方法及技术手段等也在不断发展，确定装配工艺与装夹方案及设计，从而达到对发动机装配工艺进一步的更深了解。 该毕业设计可以加强常用工具 AutoCAD 软件的使用与掌握；加快了解汽车企业生产装配工艺设计、制造及应用的过程。 汽车发动机装配的自动化程度，在一定程度上限制了汽车的自动化生产水平。因此，提高汽车发动机的自动装配生产线水准，是 目前我们必须解决的重要难题。 汽车发动机的气缸 分为缸体与气缸盖两大部分，其中缸体主要提供发动机的动力输出，而气缸盖主要提供发动机的动力来源。它将输入的燃料以化学能转化成热能形式、进而转化成发动机的动力，以实现汽车的动力与预期功用。 汽车发动机的配气机构是发动机实现其正常工作的必备机构，发动机通过配气机构的运动带动活塞的往复运动，进而实现其吸气、排气、做功等一系列的动作与功能。 弹簧座是气门组的重要固定与夹紧装置，在弹簧预紧力的作用下，锁片、气门阀、以及弹簧座的实现紧密配合，即自锁。弹簧座可大致分为正向与反向 两种固定方式。起重，正向固定一般为与水平垂直 90 度“上大下小”方式，而反向固定为与水平垂直90 度“下小上大”方式。本设计采用的是正向固定方式。 在弹簧座的自锁机构中，为了更加的保证配合的精度，有时需要在弹簧座中加入一锁片套，利用锁片套与锁片之间的紧密配合，来达到更高的技术要求。 汽车发动机气缸盖进、排气门组自动检验装置的设计，是完全自动化的检查装置，检查时间为 60s。 关键词 ： 发动机；气缸盖；气门组；检查装置；传感器 nts黑龙江工程学院本科生毕业设计 II ABSTRACT The universal mini-vehicles in China has great market, from 0.9L to 1.6L, the price for Chinas national conditions, China is developing for the current situation. One of the important parts in automotive engines, with the present design manufacturing technology, engine assembly methods and techniques are evolving such as to determine the assembly process and the clamping scheme and design of the engine assembly process so as to achieve further deeper understanding. The graduation project can enhance the use of common tools and mastery of AutoCAD software; Accelerate the understanding of automobile production assembly process design, manufacturing and application process. Engine assembly automation, to a certain extent, limit the level of automated production of motor vehicles. Therefore, improving the car engine standard automatic assembly line, is we have to solve important problems. Automotive engine cylinder block and cylinder head cylinder head is divided into two parts, of which the main provider of the engine cylinder power output, and provide the engine cylinder head main power source. It will enter the fuel to form chemical energy into heat, and then into the engines power, in order to achieve the expected vehicle dynamics and function. Automotive engine valve train is the engine must work to achieve their normal body, engine valve mechanism by the movement of the piston driven reciprocating motion, thus achieving its suction, exhaust, doing work and a series of actions and functions. Valve spring seat is an important group of fixed and clamping device, the role of preload in the spring, the locking pieces, gas patriarch, and the spring seat closely with the realization that the self-locking. Spring seat can be broadly divided into two fixed positive and negative ways. Lifting, forward fixed is generally 90 degrees with the horizontal and vertical next big small way, but the reverse is fixed at 90 degrees with the horizontal and vertical, the next big small way. This design uses a positive fixation. In the spring seat of the self-locking, in order to better guarantee the accuracy of cooperation, sometimes in the spring seat by adding a lock piece sets, the use of locking nts黑龙江工程学院本科生毕业设计 III plates and locking plates between the sets of close coordination to achieve higher technical requirements. Into the automobile engine cylinder head, exhaust valve set
