Description

Technical Field

[0001] This utility model belongs to the technical field of laser cutting machines, and particularly relates to a protection device for a laser cutting machine. Background Art

[0002] A laser cutting machine is a device that uses a laser beam with a high energy density to cut materials. The laser cutting machine emits a laser beam through a laser, and the laser beam is focused into a laser beam with a high power density through an optical path system. When the laser beam irradiates the surface of the workpiece, the workpiece quickly reaches the melting point or boiling point. At the same time, the high-pressure gas coaxial with the beam blows away the melted or vaporized metal. As the relative position of the beam and the workpiece moves, finally a cut is formed in the material to achieve the purpose of cutting.

[0003] Currently, the observation windows on the doors of laser cutting machines are generally made of transparent glass. High-temperature debris generated during the operation of the laser cutting machine is extremely likely to adhere to the glass. Over time, the accumulation of these debris may not only damage the transparent glass, but also seriously affect its perspective effect, making it difficult for users to clearly observe the internal operation of the laser cutting machine, thus reducing the use effect of the equipment. Content of the Utility Model

[0004] The purpose of this utility model is to provide a protection device for a laser cutting machine, which can blow high-temperature debris, form an air flow barrier, quickly cool the debris, avoid sticking to the protective glass, and ensure the clarity and transparency of the protective glass.

[0019] In order to make the purpose and advantages of this utility model clearer, the following specifically describes this utility model in conjunction with embodiments. It should be understood that the following text only describes one or several specific implementation manners of this utility model, and does not strictly limit the specific protection scope claimed by this utility model.

[0020] Such as Figures 1-3As shown in the figure, a protection device for a laser cutting machine includes a laser cutting machine 1. A protective door 2 is provided on one side of the laser cutting machine 1. An installation groove 3 is penetratingly opened on one side of the protective door 2. An installation frame 4 is rotatably installed inside the installation groove 3. A plug-in slot 5 is opened at the top of the installation frame 4. A protective glass 6 is inserted inside the plug-in slot 5. A buckle assembly for limiting the installation frame 4 is provided on one side of the protective door 2. A plurality of cross plates 9 are fixed on one side of the protective door 2 and span the installation groove 3. The cross plates 9 can limit one side of the protective glass 6. A blowing head for blowing air on the protective glass 6 is provided at the bottom of the cross plate 9. A cold air blower 8 is provided on the outer wall of the protective door 2 and on one side of the installation groove 3. The cold air blower 8 is connected to the blowing head through an air duct, which can blow and cool the debris generated by cutting. The structure is simple, which can prevent the high-temperature debris from sticking to the protective glass 6 and affecting the subsequent normal use of the protective glass 6. It is also convenient for installing, fixing, disassembling and replacing the protective glass 6, which is relatively labor-saving. One side of the top of the cross plate 9 is provided with an inclined sliding surface to prevent the debris generated by cutting from accumulating on the top of the cross plate 9, which is relatively practical. The buckle assembly includes an installation block 10 fixed on the outer wall of the protective door 2 and above the installation groove 3. A guide groove 11 is penetratingly opened at the top of the installation block 10. A limiting rod 13 is inserted inside the guide groove 11. A first slider is fixed on the outer wall of the limiting rod 13. A first sliding groove for sliding connection with the first slider is opened inside the guide groove 11. The arranged first slider and first sliding groove make the movement of the limiting rod 13 relatively stable. A spring 12 is fixed at the top of the first slider, and the top of the spring 12 is fixed to the inner wall of the first sliding groove. The installation frame 4 is limited and fixed by the limiting rod 13 to prevent the installation frame 4 from opening during work;

[0021] As Figures 1-2 shown, a support block 7 is provided on the outer wall of the protective door 2 and below the installation groove 3. When the installation frame 4 is turned over and opened, the installation frame 4 can be supported by the support block 7, which is convenient for taking out the protective glass 6 from the plug-in slot 5;

[0022] As Figures 1-3 shown, a pull rod is fixed above the installation block 10 at the top of the limiting rod 13, which is relatively labor-saving to pull the limiting rod 13;

[0023] As Figures 1-3 shown, a handle is fixed on the outer wall of the installation frame 4, which is convenient for operating and opening the installation frame 4 through the handle.

[0024] The working principle of this utility model is as follows: When in use, when the high-temperature debris generated by the laser cutting machine 1 contacts the protective glass 6, the cold air generated by the cold air blower 8, in cooperation with the air blowing heads on the cross plate 9, blows the high-temperature debris, so that the debris is quickly cooled and prevented from sticking to the protective glass 6. When the protective glass 6 needs to be replaced, pull the limit rod 13 upwards to cancel the limit of the installation frame 4 by the limit rod 13. Then, turn the installation frame 4 downwards through the handle, so that the installation frame 4 contacts the support block 7 for support. Then, take out the protective glass 6 from the insertion slot 5, replace it with a new protective glass 6, and then turn the installation frame 4 into the installation slot 3. Due to the elastic force of the spring 12, the limit rod 13 descends to limit and fix the installation frame 4, thus completing the installation of the protective glass 6.

[0025] The above is only the preferred embodiment of this utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of this utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of this utility model. The structures, devices, and operation methods not specifically described and explained in this utility model, unless otherwise specifically stated and limited, are implemented according to the conventional means in this field.
