Description

Technical Field

[0001] The utility model relates to the field of laser machines, in particular to a laser machine which is convenient for positioning a workpiece. Background Art

[0002] Laser machine is a device that uses laser beam to cut, engrave and mark materials. It heats the surface of the workpiece instantly by focusing a high-energy-density laser beam, causing the heated area to evaporate or melt instantly, thereby achieving material cutting, engraving and marking. Laser cutting machines are suitable for a variety of materials, such as metals, plastics, wood, textiles and ceramics, and have the advantages of high precision, high repeatability, high efficiency, automation and environmental protection. It is widely used in industrial manufacturing, construction, clothing, furniture, medical equipment and other fields, gradually replacing traditional mechanical cutting process equipment.

[0003] Laser cutting uses a focused high-power density laser beam to irradiate the workpiece, causing the irradiated material to melt, vaporize, ablate or reach the ignition point quickly, and at the same time uses a high-speed airflow coaxial with the beam to blow away the molten material, thereby achieving the cutting of the workpiece. Laser cutting is one of the thermal cutting methods. The laser cutting machines currently used often place a focusing lens in front of the light source system to focus the parallel lasers generated by the light source system into a point. Since the energy of the focus point is extremely high, the focus point is used for cutting. When performing laser cutting, the focus of the focusing lens needs to be located on the surface to be cut of the workpiece to achieve a better cutting effect.

[0004] Before processing, the workpiece needs to be positioned, and then a certain type of processing equipment is used to process the workpiece. For example, when stamping, punching, dispensing, welding and other processing operations are performed on the plate, the plate needs to be accurately positioned on the loading mechanism. Application number: CN202320959924.9, discloses a cutting positioning structure of a laser cutting machine, which is positioned from the top of the workpiece by a third positioning component, and the workpiece is close to the top of the machine tool under the limit of the third limit plate, thereby avoiding the upward deviation of the workpiece, and the first positioning component and the second positioning component are combined to clamp and position the workpiece from multiple directions to ensure the stability of the workpiece positioning, which is convenient for subsequent laser cutting. However, when the device is in use, the laser head burns and vaporizes the workpiece, and then blows away the melted material through the internal high-speed airflow. At this time, there will be more splashing sparks in the surrounding working environment. If these sparks are not handled in time, they will not only affect the cutting accuracy and quality, but also may burn the operator or release harmful gases when cutting certain materials.

[0005] Therefore, it is necessary to provide a laser machine that is convenient for positioning the workpiece to solve the above technical problems. Utility Model Content
