Problems solved by technology
[0003] The failure analysis of the guide rails of CNC machine tools shows that the worn guide rails have a great influence on the accuracy, accuracy retention, stability and shock resistance of the guide rails, which seriously reduces the operating performance of the guide rails, especially in humid air environments. Accelerated rail wear

The invention discloses a test method for electrochemical corrosion and wear of guide rails. At least three sets of guide rail test benches with the same configuration are obtained, including a bench, a guide rail and a screw nut mechanism installed on the bench, and a bracket installed on the guide rail. plate, the power system used for driving, the linear grating sensor used to detect the position of the moving parts of the guide rail, and the loading device used to load the pallet; before the test, the straightness of each guide rail was detected and recorded separately; during the test, different Concentrated salt water is intermittently sprayed on the guide rail, and the supporting plate is driven by the power system until the set test time is reached, and the straightness of each guide rail is detected separately, and compared with the recorded guide rail straightness, to detect different concentrations of salt water Influence on the straightness of the guide rail. The invention has the advantages of being able to simulate the electrochemical corrosion wear of the guide rail, analyzing the degree of influence of different concentrations of salt water on the electrochemical corrosion wear of the guide rail, and facilitating the formulation of targeted protective measures.
Description
technical field [0001] The invention relates to the technical field of testing, in particular to a testing method for electrochemical corrosion and wear of guide rails. Background technique [0002] Guide rails are widely used in life and industry, especially in CNC machine tools. They provide support and guidance for CNC machine tool parts and are the key components to ensure the effective operation of CNC machine tools. The quality of the guide rail directly affects the running performance of the CNC machine tool. Studying the quality characteristics of the guide rail is the key to ensure the performance of the CNC machine tool. The guide rail mainly provides the feed movement in the CNC machine tool, so that the moving parts reciprocate in the given direction of the guide rail, and combine with other movements of the CNC machine tool to achieve the specified function. The applications of guide rails in CNC machine tools mainly include sliding guide rails, rolling guide r...
