摘要自动化生产是将人们的双手从繁重的劳动生活中解放出来的重要手段之一，同时，在这个劳动力越来越昂贵的今天，自动化生产可以有效的减少生产成本，目前自动化生产也是制造业发展的一个重要趋势。由于人工制刷过程繁琐、复杂，还会产生对人体有害的物质，并且难以满足标准化加工的要求，使油漆刷制刷自动化的要求变的迫在眉睫，本论文将制刷机中装柄机构的设计作为本论文的主要研究对象。73682

本文介绍了油漆刷制造行业的国内外现状，除了国内绝大多数手工制造之外，其中还包括国外各种已经成熟的功能齐全的全自动生产线的设计思路、组成原理及原理图的介绍，文中对每种生产线的优缺点进行了分析，以便于后面自己做设计的时候作为参考。通过对多条生产线装柄机构实现方式的研究对比，在他们的基础上对原方案中的机构设计进行优化设计，并且针对国内现阶段制刷行业油漆刷刷头不规则的特点加入了全新的结构，设计出了可以在一次推送过程中完成刷头扩张和刷柄推入的制刷机装柄机构。

本文设计所面对的是油漆刷市场各种尺寸的刷柄，为了方便各种尺寸的刷柄的更换，所以推柄装置尺寸设计较大，以便于后期刷柄尺寸改变的时候调整方便，只要加入合适大小的模套即可。本文直接利用液压缸往复推送作为设计机构的动力，本机构设计完整的组成环节包括以下几个部分：刷柄推入装置的设计、刷头固定方式的设计，刷头扩张方式的设计、以及扩充装置扩充完毕退出方式的设计。

根据制造自动化的要求，本文完成了机械结构方面的设计和相关零件的选择设计，对于各个配件的制造方式及配件之间的安装方式进行了介绍。本文设计的油漆刷装柄机可以实现在一个动力源的情况下，一次往复，完成多种运动的功能，设计中充分使用了不同机械结构以达到预期的目的。

Design of brush handle mechanism of paint brush

Abstract Production automation is will be one of the important means to liberate the hands of the people from the heavy work life, at the same time, in the labor force is more and more expensive today, production automation can effectively reduce the production cost, the production automation is manufacturing industry development is an important trend。 Due to the artificial brush making process cumbersome and complex, still can produce substances harmful to human body, and it is difficult to meet the standardized processing requirements, paint brush brush automation requirements become imminent, the will of brush installed crank mechanism design as the main research object of study。

Is introduced in this paper paint brush manufacturing industry, the status quo at home and abroad, apart from the vast majority of domestic manual manufacturing, which also includes various foreign mature functional automatic production line design ideas, principle and schematic diagram is introduced, the advantages and disadvantages of each kind of production line are analyzed, in order to facilitate subsequent to do their own design as a reference。 Through the multiple production lines and crank mechanism to achieve the comparative study, on the basis of their of institutional design in the original scheme of optimization design, and at this stage of the domestic manufacturing industries brush paint brush head irregular to the characteristics, and joined the new structure design in a push in the process of complete pushed into the brush head expansion and a brush handle of the brush handle mechanism。

In this paper, the design of the face paint brush Market of various sizes of the brush handle, in order to replacement of the convenience of various sizes of the brush handle, so the handle pushing device size larger, to facilitate later brush handle size change when convenient adjustment, just add the appropriate size of the die sleeve。 The paper directly uses the hydraulic cylinder reciprocating push as a Design Institute of power, the mechanism design complete part includes the following parts: push the brush handle device design, the brush head is fixed mode design, brush head expansion design and expansion device expansion completed back out of the way of design。 油漆刷制刷机装柄机构设计+CAD图纸:http://www.youerw.com/jixie/lunwen_84095.html
