The invention discloses a heavy-duty machine tool body deformation automatic monitoring and alarm device, and the device comprises a data collection subsystem, a data processing and analysis subsystem, and a machine tool body deformation monitoring and alarm subsystem. The data collection subsystem comprises a laser transmission module and a PSD position sensor module, which are located in the same line. The laser transmission module transmits a signal to the PSD position sensor module, and monitors horizontal and vertical deformation amounts of a heavy-duty machine tool body. The output end of the PSD position sensor module is connected with the input end of a single-chip microcomputer module in the data processing and analysis subsystem, and an operation and control keyboard module is connected with the input end of the single-chip microcomputer module. The output end of the single-chip microcomputer module is connected with a display module and an alarm module in the machine tool body deformation monitoring and alarm subsystem. The device can monitor the deformation of the machine tool body in real time, can automatically transmit alarm information, is high in precision, is high in practicability, is high in intelligentization degree, judges whether the deformation amounts can affect the precision of the machine tool or not, and improves the prediction capability of machine tool precision.

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 deformation of a heavy machine tool bed. Background technique [0002] As the workhorse of the manufacturing industry, heavy-duty CNC machine tools are widely used in the manufacturing fields of automobiles, aerospace, and ships. They are strategic materials to measure a country's technical level and comprehensive national strength. [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.

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
