Claims

1. A high strength steel cut deformation monitoring device, characterized by: It comprises a moving frame, a strain sensor positioning frame, a strain gauge, a power supply battery pack, a micro-power wireless remote transmission module and a total display. The moving frame is arranged across a steel plate cutting platform, and guide rails are arranged on both sides of the steel plate cutting platform; the moving frame is in a door-shaped structure, and a traction frame driven by a motor is arranged at the bottom end of the moving frame to move back and forth along the extension direction of the guide rails; a pair of longitudinal guide rails are arranged on the side surface of the moving frame, and a horizontal slide rail with a scale is horizontally arranged on the longitudinal guide rails and driven in the vertical direction by a screw nut pair. The strain sensor positioning frame has a plurality of strain sensor positioning frames, and the strain sensor positioning frames are arranged at the top edge of the strain sensor positioning frame and installed on the horizontal slide rail of the moving frame by a sliding block; the strain sensor positioning frame can be adjusted in position along the extension direction of the horizontal slide rail; the strain sensor positioning frame is in a cuboid frame structure and is provided with a positioning plate at the bottom end; a positioning groove for accommodating the strain sensor is formed at the edge of the positioning plate for quick positioning and pasting of the strain sensor; the longitudinal movement of the horizontal slide rail driven by the screw nut pair enables the positioning plate at the bottom end of the strain sensor positioning frame to keep close to the surface of the steel plate to be cut on the steel plate cutting platform during pasting of the strain sensor; The strain gauge, the power supply battery pack and the micro-power wireless remote transmission module are all installed on the moving frame; a plurality of connecting lines are led out from the strain gauge and extend into each strain sensor positioning frame and are bound to the strain sensor positioning frame; the end of the connecting line is provided with a quick wiring terminal for quick plug-in communication with the output end of the pasted strain sensor; the power supply battery pack is connected to the strain sensor, the strain gauge and the micro-power wireless remote transmission module by wires and supplies power; The total display is used to receive the signal output by the micro-power wireless remote transmission module and display the signal.

2. The apparatus for monitoring cutting and deformation of a high-strength steel according to claim 1, wherein: The sliding block is provided with a threaded hole, and after the sliding block is adjusted in position along the extension direction of the slide rail, the sliding block is locked by a bolt to fix the position of the strain sensor positioning frame.

3. The apparatus for monitoring cutting and deformation of a high-strength steel according to claim 1, wherein: The screw nut pair comprises a transmission screw, a driving disc and a fixed nut; the fixed nut is installed on the side surface of the moving frame, and the transmission screw is matched with the fixed nut; the bottom end of the transmission screw is connected to the top end of the horizontal slide rail through a bearing, and the driving disc is fixedly installed on the top end of the transmission screw to drive the horizontal slide rail to move in the vertical direction by rotating the driving disc.
