Main Reduction gear screw Mechanical structure
Abstract
In the assembly of the automobile main gear case,the pneumatic gun is commonly used to tighten the screws,but this kind of operation makers the operators extremely tired,moreover,the right pre-tightening force can not be gaind.Therefore,such operation may cause inefficient production and the assembly quality can not be guaranteed.In this paper,a new screw-machine for tightening the screws is introduced which is fitted on she flexible assembly line of the main gear case.The serew-machine is controlled by an industrial control. Computer,so it can measure the serew-machine intelligently,and then the appropriatc pre-tightening force can be achieved.Thus the production efficiency and the quality of productd can be improved greatly.With stable parameters and reliable performance,the developed machine is worth applying and spreading.
