A Straightening Control System for the Linear Guide Rail

The linear guide rail has high accuracy requirement for straightness in some mechanical equipment. In order to meet the straightness accuracy of the linear guide rail, straightening machine can be used to straighten the linear guide rail in the industrial manufacturing process. Deformation and bending often occur in different planes, which is a challenge to the traditional straightening control systems. This paper proposes a control system to straighten the linear guide rail precisely. The function of the control system is modularized, which is divided into four main functional modules. Based on the analysis of functional modules of the control system, the straightening control flow is designed, and the workpiece rotation operation is added based on the previous straightening control process, which allows the straightening press head to straighten the linear guide rail at the optimal angle. This also provides a new idea for optimizing the structure of the straightening machine. The hardware and software of the control system are also designed, motion control card is the key part of the hardware, and the function of the software is divided into different functional modules. The control system is used in the straightening machine to straighten the linear guide rail. The experimental data shows that the straightened linear guide rail has a high straightness accuracy, the efficiency of the straightening process has also been improved.
