发动机拆装台架的设计
摘 要
汽车作为目前比较普遍的一种交通工具在人们的日常生活中已经占有非常重要的地位，随之带来的是汽车维修行业的兴起，随着我国汽车产业快速发展，汽车维修技术的进步也越来越迅速。我国汽车维修行业投入方式呈现多层次的特征，这决定了我国汽修企业技术水平的良莠不齐。一方面，一些实力雄厚的汽车生产企业在国内建立了售后服务网点或者是所产车型的特约维修站，带动了汽修行业整体水平的大幅提高。但另一方面，我国还有更多的人他们本身素质较低，只能凭借简陋的设备、简单的工具和多年的工作经验从事汽车维修行业。在整个汽车维修行业中，发动机的维修毫无疑问是这个行业中比较重要的一个分支，汽车发动机拆装实习台架架就是作为汽车发动机维修行业较为常见的一个辅助设备而出现的。
结合职业院校汽修专业或培训机构的汽车培训技能需要，设计一种电控汽油发动机总成拆装教学设备，便于学员进行发动机拆卸和装配实训。使学员清楚了解发动机内部的结构与功能，便于学员较快地掌握发动机的构造和原理。拆装翻转架选材要重视使用安全，要求坚固耐用，表面经喷涂工艺处理，底部带有自锁脚轮装置，可移动式，方便教学。
关键词：发动机，拆装台架，传动。
As a more popular vehicle in the daily life of the car has occupied a very important position, along with the rise of the automobile maintenance industry, with the rapid development of China's auto industry, vehicle maintenance technology progress also more Come more quickly. China's auto repair industry investment approach presents a multi-level characteristics, which determines the technical level of China's auto repair business varies greatly. On the one hand, some of the strength of the automobile production enterprises in the country to establish a service network or the production of special models of maintenance stations, driven by the overall level of the auto repair industry a substantial increase. On the other hand, there are more people in China, their own low quality, only by virtue of simple equipment, simple tools and years of work experience in the automotive maintenance industry. In the entire vehicle maintenance industry, the engine maintenance is undoubtedly the industry is more important in a branch, car engine disassembly practice platform rack as a car engine repair industry is a more common auxiliary equipment and the emergence of.
Combined with professional training institutions or training institutions of automotive training skills needs, the design of an electronic control gasoline engine assembly disassembly teaching equipment to facilitate the students to carry out engine disassembly and assembly training. So that students clearly understand the internal structure and function of the engine, so that students can quickly grasp the structure and principles of the engine. Disassembly flip frame material to pay attention to the use of security, demanding rugged, the surface by the spray process, the bottom with a self-locking casters, removable, easy to teach.
Keywords: engine, dismantling platform, transmission.
