The mounting plate 601 and the stopper 605 are respectively fixedly connected to the two ends of the top of the second slider 4. A horizontal sleeve 602 is fixedly connected to the top of the mounting plate 601. A rotating shaft 603 is inserted into the sleeve 602. The length direction of the sleeve 602 and the rotating shaft 603 is perpendicular to the moving direction of the second slider 4. One end of the rotating shaft 603 extending outside the sleeve 602 is rotatably connected to a U-shaped connecting plate 604, and the U-shaped connecting plate 604 is located on one side of the moving direction of the second slider 4.

[0062] The working principle of this embodiment is the same as that of Embodiment 1. The present invention connects three linear guide rails to form an H-shaped frame through a rolling slider. By moving the slider, the second slider 4 can be displaced in the longitudinal and transverse directions, and can be moved freely within the plane coordinate system covered by the H-shaped frame; the horizontality of the H-shaped frame is adjusted by four sets of horizontal adjustment mechanisms, so that the surface grinding device can grind various positions on the surface of the embedded steel plate at the same horizontal height to improve the horizontality of the surface of the embedded steel plate after grinding; the H-shaped frame composed of sliding connections is used to install the grinding amount adjustment mechanism and the grinding equipment, so that the grinding wheel 702 in the grinding equipment can be translated between any positions within the plane covered by the H-shaped frame, which is convenient for adjusting the grinding position and improving the flatness of the grinding surface; the distance between the grinding equipment and the grinding surface can be adjusted by the grinding amount adjustment mechanism, which is convenient for adjusting the grinding feed amount of the grinding wheel 702.

[0063] Therefore, when the surface grinding device of the present invention is used to grind the surface of the embedded steel plate, it can effectively ensure the levelness of the ground surface, and can accurately control the grinding amount to improve the flatness of the ground surface. The grinding process is highly safe and easy to operate, which can greatly reduce the workload of the operator and can significantly improve the grinding quality and efficiency of the grinding work.
