;In this paper,aiming at the development,design and manufacture of the special assembly equipment for needle roller bearings.And by a new type of limited reduction of the track wheel filling needle dedicated body design, to achieve the bearing can be successfully produced and reduce the artificial full inspection and improve the rate of non-performing and through through different aspects of the design and improvement of experimental design and simulation of various rationalization of the design, and finally this the concept of organizational design applied to other similar shapes of products for modular design. This new style reducing the track wheel needle filling special equipment it is institutions package Y-axis ball screw rail before and after the guide body, rotating Pin mechanism, Z-axis thimble mechanism and 3D optical fiber sensing module and through the programmable logiccontroller (PLC) And man-machine interface instructions to complete the two-way interactive man-machine interaction and equipment to achieve the function of automated production. The design concept of this facility is mainly based on the design of the three-axis X、Y、Z junction origins and serves as the basis for extending the key actions needed by the key agencies. With the simplest mechanical design to meet the requirements of the maximum capacity and reduce the production defects , it also improves the rate of operation of the equipment and reduces the number of invalid man-hours for maintenance and installation. The experimental results show that the design of the new type of limited-type track wheel needle-filling mechanism not only meets the original designer′s motion design requirements, but also more in line with the actual production of operating standards. And through the relevant bearing life experiment to explore and study the precision requirements of the valve swing bearing, bearing manufacturers and the market relevance and reliability comparison to meet the needs of customers and customized assembly equipment design and manufacturing . Finally , i hope to use this publication as a research case for designing R & D personnel to stimulate more creative organization design.
