Abstract

This invention relates to the field of angular contact ball bearing processing technology, and more particularly to a high-precision assembly fixture specifically designed for angular contact ball bearings. It includes an assembly box, an inner cylinder positioning assembly, an outer cylinder positioning assembly, and a temperature-conducting assembly. This invention utilizes the principle that semiconductor materials absorb and release heat at their two ends when energized, and, in conjunction with the lifting and rotating of the temperature-conducting assembly with a concentric cylinder structure, achieves flexible switching between cooling and heating. By attaching the heating / cold ends of the temperature-conducting assembly to the temperature-conducting platform, the temperature of the angular contact ball bearing is specifically adjusted, and the principle of thermal expansion and contraction is used to control the installation space. During assembly, the inner and outer cylinder positioning assemblies, working together, not only fix and limit the inner and outer cylinders respectively, but also automatically complete the installation of the balls. The installation methods are diverse, the process is highly controllable and automated, and it meets the high-precision requirements of different types of angular contact ball bearings.
