The design of column bearing pressing and riveting machine steering
Abstract: Steering column assembly is an important component of the steering system , the connection between the steering wheel and the steering is the steering mechanism . Pass plays came rotational torque to the steering wheel steering role in normal use , is widely used in cars, trains , ships and other mechanical and practical fields. Design steering column bearing press-fit mouth and riveting machine system, fitting force online testing, fitting force data real-time display , alarm function failed , to ensure the quality of products has important practical significance. This paper introduces the device is in the steering column of a total assembly line assembly station , is based on the original steering column bearing press-fit and rivet design on the opening drive , to improve it , to make more precise bearing fitting force , simplify the overall mechanical structure , reducing the power source , and to press-fit and riveting opening two processes using only one power source based on organically combined . Meanwhile, the special machine parts using common standards , combined with ingenious mechanical structure, function and achieve semi-automatic assembly line testing , with error prevention , reduce labor intensity , reducing assembly costs and other functions ; is a dedicated steering column applies to the industry equipment.
