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

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.
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.
