摘要

本文是根据无锡迪奥机械厂轴承内外圈生产线改造项目要求，针对工人手工上料易出现危险，且效率较低的问题，设计一套轴承内外圈加工专用机床上料机构，使其能够代替工人手工上料，保证工人操作的安全性，并提高生产效率。

论文根据轴承内外圈的特点，对其上料机构进行了合理的设计。此上料机构主要实现了坯料的自动定位、夹紧以及工件的回放等功能。这一系列运动都是由气缸驱动获得。本设计中的设计部分主要包括：上料机构设计；料道设计；夹紧机构设计；驱动系统等。确定了上料机构的具体尺寸后，利用UG软件对上料机构的零件进行参数化建模，并对整体结构进行虚拟装配。然后将装配体导入UG软件的运动仿真界面，并利用软件进行运动学仿真和动力学仿真。分析仿真结果，得出相应结论。最后对轴承内外圈加工专用机床上料机构进行优化设计，提高其稳定性，可靠性，让本设计能够真正的投入到日常生产操作中，使其切实能够为轴承厂的生产线改造做出贡献。

Abstract

This article is based on the requirements of the bearings inside and outside circle line renovation project of the wuxi dior machinery, and it aims to solve the problem that the manual feeding by workers which is dangerous for workers, and it has low efficiency, therefore a set of bearing inner and outer circle machining machine tool feeding mechanism is designed to replace the manual feeding of workers, and ensure the security of workers when operating, and improving producing efficiency.

This paper provides a reasonable design of the feeding mechanism according to the characteristics of the bearing inner and outer circle. The feeding mechanism mainly achieves the following functions: the automatically positioning, clamping and artifact-play backing of the billet, etc. This series of movement is driven by cylinder. The design part of this design mainly includes: the design portion of feeding mechanism; material design; the design of Clamping mechanism; Drive systems, etc. The method is: firstly determining the dimensions of the feeding mechanism, and then using UG software for parametric modeling of parts of the feeding mechanism, after that, doing virtual assembly to the overall structure; then importing the assembly body to the motion simulation interface of UG software, and using the software to do kinematics simulation and dynamics simulation. Thereafter, analyzing the simulation results, and getting the corresponding conclusions. Finally the optimization design of bearing inner and outer circle machining machine tool feeding mechanism is done, to improve its stability, reliability, and to make the design truly enter into the daily production operation, make it practical and able to contribute to bearing factory production line modification.

Key words: feeding agencies; parametric modeling; virtual assembly; motion simulation
