DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods:

[0026] like Figure 1-2 As shown, the utility model provides a laser cutting machine that is easy to replace a cutting head, including a laser cutting workbench 1, a sliding frame 2 is arranged on the top of the laser cutting workbench 1, a sliding mainframe box 3 is slidably connected to the top of the sliding frame 2, a laser cutting head 4 is arranged on the left side of the bottom end of the sliding mainframe box 3, and adjustment mechanisms 5 are arranged on the top of the left front and rear sides of the laser cutting workbench 1. The laser cutting head 4 includes a connecting sleeve 41, which is fixedly connected to the left side of the bottom of the sliding mainframe box 3, a cutting head body 42 is slidably inserted in the middle of the connecting sleeve 41, and a rotating ring 43 is rotatably connected to the outer surface of the connecting sleeve 41 , a bevel gear ring 44 is fixedly connected to the inner side of the rotating ring 43, and three bevel gears 45 are meshed and connected in an annular array inside the bevel gear ring 44. Three sliding grooves 1 are opened in the internal annular array of the connecting sleeve 41, and the bevel gear 45 is movably connected inside the sliding groove 1. A first screw rod 46 is fixedly connected to the side of the bevel gear 45 close to the cutting head body 42, and a fixed plug post 47 is threadedly connected to the outer surface of the first screw 46.

[0033] Under the pushing of the tightening spring 585, the circular plate 583 can be pressed against the fixed plug plate 584, so that the fixed plug plate 584 is inserted into the interior of the positioning groove to fix the collection box 57. Thereafter, by rotating the knob 581, the rotating pressure plate 582 can press the circular plate 583, so that the fixed plug plate 584 can be retracted, and the collection box 57 can be pulled out by pulling the knob 581, making it convenient to pour out the impurities inside.

[0034] The following is a detailed description of the working principle of the laser cutting machine that is easy to replace the cutting head.

[0035] like Figure 1-5 As shown, when the laser cutting machine is in use, the rotating ring 43 can drive the bevel gear ring 44 to rotate, and drive the bevel gear 45 to rotate, so that the first screw 46 drives the fixed pin 47 to be pulled out from the inside of the fixed groove, which is convenient for taking out the cutting head body 42 and replacing it with a new cutting head body 42. By rotating the rotating ring 43 in the opposite direction, the new cutting head body 42 can be fixed by the fixed pin 47, and then the cutting workpiece is placed on the laser cutting workbench 1.
