Research on Design of Electrode Holder Turning Fixture Based on Finite Element Analysis
In order to solve the turning fixture positioning accuracy of the electrode base part in the welding system of an automobile frame,the feasible fixture structure scheme is worked out through the analysis of the processing technology of the electrode base part,and the special eccentric fixture of the corresponding working procedure is designed.To further ensure the overall accuracy and mechanical properties of the fixture,the influence degree and its change rule of three factors affecting the accuracy of fixture positioning element,such as rotating speed,eccentric quality and eccentric distance,are studied systematically by means of NX finite element method,and the accuracy and reliability of fixture are evaluated.The design and reserch provide a theoretical basis for the development and improvement of the same kind of fixture.
