[0002] The laser cutting machine bed is a machine that focuses the laser emitted from the laser into a high-power density laser beam through the optical path system. The laser cutting process replaces the traditional mechanical knife with an invisible light beam. It has the characteristics of high precision, fast cutting, no restrictions on cutting patterns, automatic typesetting to save materials, smooth incisions, and low processing costs. It will gradually improve or replace traditional metal cutting process equipment.

[0025] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 The utility model provides a technical solution: a laser cutting machine body with a protective device, comprising a laser cutting machine 1, a cutting moving assembly 2, a cutting assembly 3, and a laser cutting head 4. Two guide plates 12 are respectively welded to the left and right side walls of the cutting assembly 3, a groove 13 is provided on the side surface of the guide plate 12 away from the cutting assembly 3, and a guide groove 14 is respectively provided on the front and rear side walls of the inner cavity of the groove 13, and the tops of the guide groove 14 and the groove 13 are both open, so that the protective cover 5 can be pulled out from the groove 13, thereby achieving the purpose of disassembling the protective cover 5. The limiting plate 6 is welded to the front side wall of the cutting component 3, and the limiting holes 19 are evenly arranged on the front surface of the limiting plate 6. The protective component can be raised and lowered, and it is arranged on the outside of the cutting component 3. When the laser cutting head 4 is exposed, the protective cover 5 of the protective component descends to cover and protect the laser cutting head 4 to prevent it from being damaged due to bumps. The limiting component is arranged on the outer wall of the protective component, and it is used in conjunction with the limiting plate 6 and the limiting hole 19 to control the lifting and lowering of the protective cover 5, so that it can be lowered when protection is needed and raised when it is not needed, thereby improving practicality.

[0026] See also Figure 5 , Figure 6 The protective assembly includes a protective cover 5, two protrusions 15 are welded to the inner walls on both sides of the top of the protective cover 5, the protrusions 15 are matched with the grooves 13, and can slide up and down in the grooves 13, thereby driving the protective cover 5 to move up and down, and the cylinder 16 is rotatably connected to the front and rear side walls of the protrusions 15 through the bearing, and the cylinder 16 is matched with the guide groove 14, and it is installed in the groove body of the guide groove 14, the purpose of which is to improve the lifting stability of the protective cover 5 and guide the lifting of the protective cover 5. The cross section of the protective cover 5 is U-shaped, the purpose of which is to provide more protection for the laser cutting head 4, the through hole 20 is matched with the limiting hole 19, and it is opened on the top wall of the protective cover 5, and the purpose of setting the through hole 20 is to facilitate the limiting column 9 in the limiting assembly to move forward and backward smoothly, so that the rear end column of the limiting column 9 can be inserted into the limiting hole 19, and then the protective cover 5 is limited and fixed at the required position.

[0027] The limiting assembly includes a fixing frame 7, a shift block 8, a limiting column 9, a stop plate 10, and a spring 11. The cross-section of the fixing frame 7 is U-shaped. The fixing frame 7 is welded to the top front side wall of the protective cover 5. The limiting column 9 is located in the inner cavity of the fixing frame 7, and the rear end column of the limiting column 9 can be inserted into the limiting hole 19 on the surface of the limiting plate 6 through the hole cavity of the through hole 20. The front end column of the limiting column 9 can move through the front side wall of the fixing frame 7. The shift block 8 is welded to the end of the limiting column 9 away from the cutting assembly 3. The purpose is to enable the limiting column 9 to move forward and backward through the shift block 8, thereby determining whether to limit the protective cover 5. The butt plate 10 and the spring 11 are both located in the inner cavity of the fixing frame 7, and the butt plate 10 is welded to the cylindrical surface of the limiting column 9, the spring 11 is sleeved on the surface of the limiting column 9 and the spring 11 is located on the side of the butt plate 10 away from the cutting assembly 3, the purpose of which is to make it possible for the protective cover 5 to be lowered to protect the laser cutting head 4, by only pulling the shift block 8 forward to drive the limiting column 9 to move forward, the rear end column of the limiting column 9 can be pulled out from the limiting hole 19 on the surface of the limiting plate 6, thereby releasing the limiting fixation of the protective cover 5, and allowing it to be lowered, and during the lowering process, The protrusion 15 and the cylinder 16 move along the groove 13 and the guide groove 14 respectively, and the limit column 9 drives the abutment plate 10 to squeeze the spring 11 during the forward movement. Then, when the protective cover 5 drops to the required position, the shift block 8 is released and the limit column 9 can be automatically moved backward under the action of the spring 11 and inserted into the corresponding limit hole 19 to fix the protective cover 5 there. This avoids the problem that when the laser cutting head 4 of the existing laser cutting machine body is in an exposed state, there is a lack of a structure for exclusive protection of the laser cutting head 4, which easily leads to damage of the laser cutting head 4 due to external collision.

[0028] When the wiring harness or laser cutting head 4 at the bottom of the cutting assembly 3 fails and needs maintenance, in order to avoid inconvenience in maintenance, a raised column 17 is set and welded on the top wall of the guide plate 12, and the rotating block 18 is rotatably connected to the column surface of the raised column 17 through a bearing. The purpose is to be able to rotate the rotating block 18 to one side from directly above the guide groove 14. At the same time, the limiting column 9 is pulled out of the limiting hole 19, so as not to block the protrusion 15 and the cylinder 16 from sliding out of the groove 13 and the guide groove 14, and then the protective cover 5 can be removed from the entire cutting assembly 3, thereby avoiding the problem that the existing large protective structure is not conducive to the maintenance of the wiring harness and laser cutting head 4 at the bottom of the cutting assembly 3 because it cannot be disassembled.
