Comparative Analysis of Rotation Welding Positioners Based on Friction Forces

Abstract

In this paper a two solution of rotation welding positioners are presented. The presented welding positioner can be used for a various dimension of workpieces. First of the presented solutions is a conventional one. As the conventional solution it can be purchased at market as machine. A concept of second solution is presented in one of the authors previous papers. This paper presents way of functioning for both solutions. Also, in this paper is presented a friction forces determination, and its dependence of the workpiece position. A detailed mathematical model for friction forces are presented and for one size, the biggest one allowed to be on device, the reaction and friction forces are calculated. The conducted analysis is used for comparison between friction forces in conventional and new concept design. The paper concludes with clearly pointed advantages and disadvantages of the proposed new concept related to the conventional solution. At the very end the future research plans and directions are given.
