Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting machines, and in particular to a profile clamping device for a laser cutting machine. Background Art

[0002] The laser cutting machine focuses the laser light emitted from the laser into a high-power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point. At the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, the material is eventually cut, thereby achieving the purpose of cutting.

[0003] After searching, the utility model patent with announcement number CN217859458U discloses a profile clamping device for a laser cutting machine, including a linear moving module fixed to a frame, a second linear guide module installed on a moving seat, a third linear guide module perpendicular to the second linear guide module installed on a moving seat, a slider of the second linear guide module installed with a push seat, a slider of the third linear guide module installed with a left clamping arm and a right clamping arm respectively, a rotatable roller member is connected to the left clamping arm and the right clamping arm and located on the opposite surface, a connecting rod member is connected to one end of the left clamping arm and the right clamping arm, and the other end of the connecting rod member is connected to the push seat, and the cylinder push rod of the moving seat is connected to the push seat. Therefore, the front end of the profile steel is clamped by the roller member and moves forward stably during the pushing process, so the profile steel can be effectively prevented from damaging the parts of the laser cutting machine during the pushing process, and the position stability of the laser cutting machine feeding at the laser cutting head is greatly improved, and the cutting processing accuracy of the laser cutting machine is effectively improved.

[0004] However, the above patent still has the following shortcomings: during the forward movement of the profile steel, although the side of the profile steel is clamped and limited by the roller, the bottom is not supported. During the forward movement of the profile steel, it is easy to rub against the top of the third linear guide module, causing damage to it; in addition, since there is no limit on the top of the profile steel, the profile steel is prone to longitudinal movement during the forward movement, affecting the processing efficiency. For this reason, we propose a profile clamping device for a laser cutting machine. Utility Model Content
