This book introduces four modules, including machining long lead screw and worm, eccentric parts and multi-throw crankshaft, gearbox, and assembly, with tasks and subtasks in each module, with regard to the workpiece diagram recognition, processing analysis and calculation of various parts, such as long lead screw, multi-start thread, multi-start worm, double eccentric parts, four-throw crankshaft, gear reducer, worm gear reducer, bevel gears, bisector parts, mold, combined shaft and kit, as well as their clamping and positioning methods, processing methods, dimensional and geometric accuracy test methods, surface quality assurance methods, common quality problems and preventive measures or solutions, etc. This book can be used as a teaching book for application-oriented undergraduates in colleges and universities, mechanical majors, mechatronics and other related majors in higher vocational colleges, as well as a reference book or skill training book for relevant technicians.
This book aims at providing high-quality technical skills training and educational concepts to Lancang-Mekong countries so as to better serve the Belt and Road Initiative and the Lancang-Mekong Vocational Education and Training Center. Adhering to the modern apprenticeship talent training model and with the guidance of requirements of technical skills and theoretical knowledge for the advanced lathe workers in the newly revised national vocational qualification standard, this book is compiled with reference to the actual production of the enterprise and the actual operation of skilled workers, combined with the development level of the local manufacturing industry and the training equipment used.
In terms of contents, this book strives to highlight practicability and operability, ability-oriented and guided by practical work tasks, taking projects as the carrier. It adheres to the principle of project-based teaching mode and combines theory with practice, focusing on practice, supplemented by theory with sufficient introduction to theoretical knowledge. With the emphasis on practice and the cultivation of hands-on ability, the book is compiled through practicing according to the requirements of practical tasks, from shallow to deep, from easy to difficult. The scientific education theory of systematic working process is flexibly applied, and the knowledge and skills that students need to master are fully reflected in each module and specific work tasks.
The book designs four modules: machining long lead screw and worm, machining eccentric parts and multi-throw crankshaft, machining gearbox and machining assembly, with tasks and subtasks in each module. At the beginning of each task, the theoretical basic knowledge required in the task is compiled, so as to combine theory with practical work, and to make the book suitable for readers with or without professional foundation.
The modules and tasks designed in this book are all from practical production cases and skill appraisal, and can meet the requirements and regulations of theoretical knowledge and related skills for the advanced lather in national vocational qualification standard. In order to in line with international teaching materials, this book is written in Chinese and English. It can not only meet the learning needs of domestic readers for English of machinery related majors, but also be applied to the training of overseas related skills and the self-study of foreign readers.
