Description

Technical field [0001] The invention belongs to the technical field of intelligent numerical control machine tools, and relates to an automatic monitoring and alarm device for bed deformation of a heavy-duty machine tool. Background technique [0002] As the working machine of the manufacturing industry, heavy-duty CNC machine tools are widely used in automobile, aerospace, shipbuilding and other manufacturing fields. They are strategic materials to measure a country's technical level and comprehensive national strength. [0003] In the process of designing, manufacturing, and using CNC machine tools, due to the incomplete elimination of residual stress, environmental temperature changes, and the influence of factors such as the gravity of the machine tool, the deformation of the machine tool will cause the geometric accuracy of the machine tool to exceed its use range. [0004] After the heavy-duty CNC machine tools are put into use, companies generally calibrate the accuracy of the...

Problems solved by technology

[0003] In the design, manufacture and use of CNC machine tools, due to the incomplete elimination of residual stress, the influence of environmental temperature changes and the gravity of the machine tool, the deformation of the machine tool will make the geometric accuracy of the machine tool exceed its use range

[0004] After heavy-duty CNC machine tools are put into use, companies generally calibrate the accuracy of machine tools regularly according to experience. The workload is heavy and the efficiency is low, which can no longer meet the needs of heavy-duty precision machine tools for precision, efficiency and manufacturing costs.

At present, domestic and foreign enterprises are still in a blank state in the research and development of the deformation monitoring technology of the heavy-duty machine bed, and there is no measuring instrument that can monitor the deformation of the heavy-duty machine bed online in real time, so it is impossible to inform the operator in time to check the accuracy of the machine tool
