Description

Technical Field

[0001] The invention relates to a laser cutting machine, in particular to a multifunctional laser cutting machine. Background Art

[0002] The laser cutting machine focuses the laser emitted from the laser into a high-power density laser beam through the optical path system. As the relative position of the laser beam and the workpiece moves, a slit is eventually formed in the material, thereby achieving the purpose of cutting. In addition, the surface of the workpiece can be marked with a high-speed galvanometer, which has multiple functional uses.

[0003] With the advancement and development of science and technology, the size of laser cutting machines is becoming smaller and smaller. At present, when the existing miniaturized laser cutting machines are in use, the distance between the light source of the laser cutting machine and the bottom of the protective box is fixed, which leads to limited operating space. Therefore, when processing some slightly larger workpieces, it is often necessary to remove the bottom plate of the protective box and use pads to raise the protective box to process some slightly larger workpieces. Such operation has many inconveniences. Not only is the operation troublesome, but the raised protective box and the laser cutting machine inside it have poor stability in use, and there are certain safety hazards.

[0004] In summary, a multifunctional laser cutting machine with easy-to-adjust operating height is proposed. Summary of the invention

The protective pad 10 is taken out after use, which is convenient for cleaning the debris remaining on the protective pad 10, and is conducive to keeping the protective frame 2 and the cutting table 1 clean and tidy, achieving the purpose of easy cleaning and easy use. A base 4 is installed at the bottom of the cutting table 1, and columns 40 are respectively arranged at the four corners of the base 4. A slider 411 corresponding to the column 40 is arranged at the lower outer side of the protective frame 2, and a slide groove 410 for the slider 411 to move up and down is opened on the column 40. An adjustment component is arranged between the base 4 and the protective frame 2, and the working position of the protective frame 2 and the laser cutting machine 3 can be adjusted by the adjustment component, thereby achieving the purpose of convenient processing of workpieces of different volumes.

[0032] For further information, see Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8 and Fig. 9 As shown, the adjustment component includes a connecting block 41, a connecting rod 42, an adjustment seat 43, a guide frame 44 and an adjustment screw 45. The base 4 and the left and right sides of the protective frame 2 are hingedly connected with two groups of connecting blocks 41 through mounting blocks. The number of each group of connecting blocks 41 is two. The ends of the same group of connecting blocks 41 on the front side are connected in series through the connecting rod 42, and the ends of the same group of connecting blocks 41 on the rear side are also connected in series through the connecting rod 42. The middle parts of the two connecting rods 42 are movably sleeved with an adjustment seat 43, and a guide frame 44 is slidably inserted between the two adjustment seats 43.

[0035] For further information, see Figure 3 As shown, anti-skid pads 8 are also included. Anti-skid pads 8 are embedded in the four corners of the bottom of the base 4, which are beneficial to the purpose of anti-skid and shock absorption.

[0036] When processing some slightly larger workpieces, the two adjustment seats 43 and the connecting rod 42 can be driven away from each other by twisting the adjusting screw 45, so that the connecting block 41 in the folded state can be unfolded and extended, thereby driving the protective frame 2 thereon to be lifted upward under the support of the connecting block 41, and the slide groove 410 can provide a guiding effect for the slider 411, so that the laser cutting machine 3 in the protective frame 2 can be lifted upward steadily, which is conducive to conveniently adjusting the processing height of the laser cutting machine 3, so that the processing space can be conveniently adjusted according to workpieces of different volumes, which is conducive to processing workpieces of different volumes. , it is highly practical and has achieved the purpose of convenient operation and easy use; when the protection frame 2 is lifted upward, the gap between the front and rear sides of the bottom of the protection frame 2 and the bottom of the cutting table 1 gradually increases, through the blocking effect of the protective cover 6, and the magnetic attraction of the magnetic block 21 after the cover 20 is closed, it is conducive to forming a closed space inside the protection frame 2, and then through the exhaust effect of the exhaust fan 70, it is conducive to the discharge of the exhaust gas generated by the laser cutting machine 3 inside the protection frame 2 when processing the workpiece, and the convex ring 72 of the exhaust pipe 7 can be connected to an external air pipe, and then one end of the air pipe can be led to a ventilated place outdoors, avoiding the exhaust gas from covering the room and affecting the working environment.
