The lower surface of the machine tool is fixedly connected with support legs. Guide rails I are fixedly connected to both sides of the machine tool. A gantry slides on the outer surface of the guide rail I. The movement of the gantry and the cutting machine drives a plasma cutting gun to cut the steel plate. During cutting, the four corners of the steel plate are clamped by positioning angle plates, so that the steel plate is more stable, the cutting is more accurate, and the cutting quality is improved.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention can adaptively adjust and clamp and fix steel plates with different lengths, widths and thicknesses through the conveying mechanism. When in use, first drive the upper positioning mechanisms on both sides to slide outwards, then place the steel plate on the positioning base plate, and then automatically drive the upper positioning mechanisms to slide inwards through the positioning motor.

When vertical cutting of the steel plate is required, the cutting device can be driven by the first driving motor to move along the cross frame, or the entire steel plate can be rotated 90 degrees by the rotating base. In addition, when the rotating base drives the steel plate to rotate at different angles, different and complex various steel plate structures and cutting seams can be obtained, which improves the cutting effect and cutting efficiency of the steel plate cutting device.

Therefore, before grinding, first, the sliding plate and the clamping plate are driven to move outward by the adjusting motor and the clamping motor. When the cutting seam is a straight line or an oblique line, the entire moving seat is driven by the cooperation of the conveying mechanism and the rotating base. When the cutting seam is a curve, while driving the moving seat to move, the angle of the rotating base can be adjusted at any time by the rotating motor, which improves the grinding effect of the steel plate cutting device.
