Abstract

This thesis belongs to the mechanical structure design of the paper, the mechanical structure design of the paper is through studying in school of mechanical design theory and in practice in the factory the actual learning, appropriate completed a mechanical structure design, ultimately meet the expected design goal, makes the final design of the machine can complete the design index requirements etc..

This thesis is of vertical online adaptive screw assembly platform structure design, adaptive screw assembly platform is screw assembly manufacturing machine assembly is composed of the main equipment, bear the screw assembly manufacturing operation reliable send a lock screw of the action, the agencies frequently, internal components between serious wear and tear is screw assembly machine as a whole composed of equipment in the most easy to damage is one of the important equipment. This design is based on adaptive screw assembly platform structure design and research, design a adaptive screw assembly platform, by sending a lock mechanism lock screw machine operation of screw assembly work, ensure that the technical performance, screw assembly work parameters meet the requirements of design, in the vertical online adaptive screw assembly platform the structure of the development process, appropriate organization of reducing cost to save materials, screw assembly process, shorten the development cycle, improve efficiency, screw assembly work extended screw assembly machine service life and work efficiency, it is very necessary and important, but the right of the screw assembly platform has advantages of saving the manufacturing development cycle. Has a very important significance for reducing the cost of assembling screw design.

This paper describes the adaptive screw assembly platform device structure and working principle of the arrangement, in determining the design scheme based on complete the send a lock screw machine transmission mechanism design, and on the design of the structure of rational layout analysis and mechanical stiffness, strength check, so that the screw assembly platform to complete, such as screw assembly send a lock screw, and according to the design of various parts of the detailed parameters, the final use of AutoCAD drawing software rendering the overall assembly drawing and the transmission mechanism of the parts of the map.

Keyword: vertical automatic screw assembly platform; structure design; AUTOCAD drawing software
