摘要推力滚针轴承全自动装配机是实现滚道圈、滚针和保持架组件组成装配体的装备。本设计所选用的轴承为标准的推力滚针轴承AXK7510,根据要求需装配40枚滚针到相应保持架组件孔中。在国内目前装配滚针方法还比较落后,装配速度低,装配质量也无法保证。因此,本文对推力滚针轴承全自动装配系统进行了设计和研究。33255
本文分析了装配难点,提出了滚针轴承装配新方法,介绍了推力滚针轴承全自动装配机的功能和主要结构,并使用了可编程控制器技术完成对滚针轴承(合格与否)的分选。
本文在总体机构及工作过程的基础上,详细阐述了推力滚针轴承全自动装配机的机械系统结构设计,主要由布置滚针机构、棘轮机构、槽轮机构、按压机构和分选机构组成。
为达到轴承装配时间小于5S/套的目的,对测控系统的硬件进行了设计和选择,硬件部分主要包括 PLC 和驱动电机。最后回归于软件设计,包括软件开发流程图等。
    本文设计的推力滚针轴承全自动装配系统可以实现集滚针高速布置,装配为一体,可实现自动加载装置自动加载撤销功能,编程方便,而且整个控制过程简单。

 Abstract Thrust needle roller bearing automatic assembly machine is to achieve the raceway ring, needle roller and cage assembly of components and equipment. The design chosen as the standard bearing thrust needle roller bearings AXK7510, according to the requirements need to assemble 40 needle into the corresponding hole in the cage assembly. Needle assembly method in China at present is still relatively backward, low speed of assembly, assembly quality can not be guaranteed. Therefore, thrust needle roller bearing automatic assembly system is designed and studied. 源自$六l维,论:文w网)加7位QQ3249^114 www.lwfree.cn
This paper analyzes the assembly difficulties, proposed a new method for needle bearing assembly, describes the features and main structure thrust needle roller bearing automatic assembly machine, and the use of the programmable controller technology to complete the needle roller bearings (qualified or not) sorting.
Based on the overall organization and the work process, the detail of the thrust needle roller bearing automatic assembly machine mechanical design system, mainly by the arrangement of the needle mechanism, ratchet mechanism, geneva mechanism, a pressing mechanism and sorting mechanism.
In order to achieve the purpose of the bearing assembly time of less than 5 seconds per sets, hardware monitoring and control system has been designed and options, including hardware PLC and the drive motor. Finally, return to the software design, software development flow chart.
    This design of the thrust needle bearing automatic assembly systems can achieve high-speed set needle arrangement, the assembly as a whole, can achieve automatic loading device to automatically load the Undo function, programming convenience, and the whole control process is simple.
