Abstract：

A problem has been found in an aluminum alloy forging production line that when the machine hand places an aluminum alloy bar to a specified position, the position of the bar is not accurate. After a preliminary observation, the cause was confirmed as the deformation of the clamping jaw. In order to analyze further, a 3D model of the clamping jaw was established by Solidworks, and its finite element model was established by Solidworks Simulation. Therefore, a static analysis was carried out. Based on the finite element analysis results, the deformation positions and causes were found out, and the clamping jaw's structure was improved. Furthermore, the improved clamping jaw was analyzed by the Solidworks Simulation again, and the rationality of structure improvement was verified preliminarily. Finally，taking the improving method on the model as a reference, the clamping jaw's structure was improved actually. Through the actual test results, it is confirmed that the improvement is reasonable and effective.
