为了解决一个实际的工业问题，进行了开发研究：在焊接过程中抵消工件的轴向位移（轴向漂移或轴向蠕变）。文献中找到的解决方案通常提供足够的结果;然而，它们机械复杂，购买和维护成本高。本文提出了一种机械上简单且廉价的解决方案。轴向漂移是用低成本定制的接触式位移传感器测量的。该传感器无需校准或设置操作即可测量轴向漂移。它非常坚固，以便在工业条件下正确运行。气动缸使空转转向辊沿着轨道移动，从而改变空转转向辊的纵向位置以抵消轴向漂移。空转转向辊的位置由控制算法控制，该控制算法由一组规则组成。为了验证所提出的解决方案，进行了测试，该解决方案可应用于现有的车削辊，从而显着降低成本。
Development research has been carried out in order to solve a practical industrial problem: to counteract axial displacement (axial drift or axial creep) of workpieces during the welding process. Solutions found in the literature generally provide adequate results; however, they are mechanically complex with high purchase and maintenance costs. A mechanically simple and inexpensive solution is proposed in this paper. Axial drift is measured with a low-cost custom-built contact displacement sensor. This sensor can measure axial drift without calibration or set-up operations. It is highly robust in order to function correctly in industrial conditions. A pneumatic cylinder moves the idle turning roll along a rail, modifying the longitudinal position of the idle turning roll in order to counteract axial drift. The position of the idle turning roll is controlled by a control algorithm, which consists of a set of rules. Tests were carried out in order to validate the proposed solution, which can be applied to existing turning rolls thereby significantly reducing costs.
