Technical Field

[0001] The utility model relates to the technical field of cutting machines, in particular to a cutting machine for steel processing. Background Art

[0002] At present, in the actual use of cutting saws in the prior art, most of the equipment processing adopts manual assistance to turn the workpiece in order to complete the cutting of different angles and different sides. Poor positioning accuracy leads to poor cutting accuracy, which can easily cause misalignment between the workpiece and the cutting saw, resulting in cutting errors.

[0003] The patent with the authorization announcement number CN205519904U discloses a cutting saw, which includes: a workbench; a saw frame; a fixed jaw to locate the cutting angle of the workpiece; a connecting piece connected to the workbench; a cam wrench with a cam surface, which is matched with the connecting piece, and the cam wrench can rotate between a first rotation position and a second rotation position under the action of an external force, and the cam surface rotates between the first rotation position and the second rotation position accordingly, and when the cam surface is in the first rotation position, the cam surface and the fixed jaw are in an interference fit. When cutting the workpiece at an angle, first draw a cutting line on the workpiece, clamp the workpiece by the auxiliary fixed jaw, and adjust the angle of the workpiece by rotating the fixed jaw, so that the drawn cutting line coincides with the movement trajectory of the saw blade, thereby completing the inclined cutting of the workpiece.

[0004] Although the above-mentioned cutting machine can adjust the angle of the workpiece by rotating the fixed jaws, it is difficult to ensure that the drawn cutting line coincides with the actual cutting line when adjusting the angle of the workpiece, resulting in unstable cutting accuracy.
