A pre-embedded device for laser processing of steel plates

Abstract

This utility model relates to the field of laser equipment processing technology, and provides a pre-embedded device for laser processing of steel plates. The device includes an embedded part positioning module located above a base platform, comprising an adjustable clamping mechanism and a position sensor; a laser processing window located in the center of the base platform, corresponding to the laser head's movement trajectory; and a cooling system integrated inside the base platform, including coolant channels and heat dissipation fins. This utility model employs closed-loop control of the position sensor and clamping mechanism to provide real-time feedback on the embedded part's position offset, reducing positioning error compared to traditional tooling. A spiral-wound coolant channel covers the entire area of ​​the laser processing window, and combined with the auxiliary heat conduction of the heat dissipation fins, lowers the temperature of the processing area. A high-temperature resistant quartz glass shield automatically closes the window at the moment of laser triggering, preventing molten slag splashes and maintaining the cleanliness of the embedded part's surface.
