Therefore, they should not be construed as limitations on this utility model.

[0046] Example:

[0047] See Figures 1 to 15 A bed beam protection structure for a laser cutting machine includes a bed body 1, a parallelogram mechanism 2, a support frame 3, a sliding frame 4, and a protective plate 5.

[0048] See Figures 1 to 5 The top of the bed body 1 is provided with multiple sword grid modules 11 along the longitudinal direction, the side of the bed body 1 is provided with multiple windows 12 along the longitudinal direction, and the interior of the bed body 1 is provided with multiple crossbeams 13 along the longitudinal direction. The crossbeams 13 are an integral structure with the bed body 1.

[0049] See Figure 6 and Figure 7 The parallelogram mechanism 2 includes a first rod 21, a second rod 22, a third rod 23, and a fourth rod 24, which are hinged end-to-end. The first rod 21 and the third rod 23 are parallel, and the second rod 22 and the fourth rod 24 are parallel. See also Figure 3 The first rod 21 is welded and fixed to the bottom of the crossbeam 13.

[0050] See Figure 10 The support frame 3 includes a support frame body 31 and a tie rod 32, which is welded and fixed to the side of the support frame body 31. See also Figure 5 The pull rod 32 is located inside the window 12 at the end furthest from the support frame body 31. See also Figure 10 The support frame body 31 is welded and fixed to the third rod 23 in the parallelogram mechanism 2.

[0051] See Figure 6 A first square column 311 is welded and fixed to the top of the support frame body 31, and a second square column 312 is welded and fixed to the top of the first square column 311. Both the first square column 311 and the second square column 312 refer to columns with a square cross-section, and the side length of the second square column 312 is greater than the side length of the first square column 311.

[0052] See Figure 7 and Figure 8The sliding frame 4 is provided with a stepped hole, which includes a first sliding hole 41 and a second sliding hole 42 connected sequentially from bottom to top. The first square post 311 slides in the first sliding hole 41 in the transverse direction, and the second square post 312 slides in the second sliding hole 42 in the transverse direction.

[0053] See Figure 11 Multiple protective plates 5 are laid on the sliding frame 4, and the protective plates 5 are made of graphite plates.

[0054] The working principle of this embodiment is as follows:

[0055] See Figures 2 to 5 In the shown configuration, the support frame body 31 abuts against the side of the crossbeam 13. The angle between the first rod 21 and the second rod 22 in the parallelogram mechanism 2 is minimized, the distance between the first rod 21 and the third rod 23 is minimized, and the distance between the support frame body 31 and the crossbeam 13 is minimized. The sliding frame 4 is located directly above the crossbeam 13, and the protective plate 5, laid on the sliding frame 4, is also located directly above the crossbeam 13, thus shielding the crossbeam 13. During laser cutting operations, the protective plate 5 protects the crossbeam 13 from laser damage.

[0056] Figures 12 to 15 With all sliding frames 4 pulled out from window 12, the angle between the first rod 21 and the second rod 22 is 90°, the parallelogram mechanism 2 is in a rectangular state, the distance between the third rod 23 and the first rod 21 is at its maximum, and the distance between the support frame 3 and the crossbeam 13 is at its maximum.

[0057] When it is necessary to replace the protective plate 5 above a certain crossbeam 13, the following operations need to be performed:

[0058] (1) The worker pulls the lever 32 out from the window 12. The lever 32 drives the support frame body 31 to move together. Specifically, the support frame body 31 swings in an arc with the hinge of the first rod 21 and the second rod 22 as the center of rotation, so that the support frame body 31 not only leaves the crossbeam 13, but also moves closer to the window 12. The sliding frame 4 located on the top of the support frame body 31 moves away from above the crossbeam 13.

[0059] During the movement of the support frame body 31, the angle between the first rod 21 and the second rod 22 gradually increases, the distance between the first rod 21 and the third rod 23 gradually increases, and the distance between the support frame body 31 and the crossbeam 13 gradually increases.

[0060] When the angle between the first rod 21 and the second rod 22 increases to 90°, the parallelogram mechanism 2 is in a rectangular state, the distance between the third rod 23 and the first rod 21 is at its maximum, and the distance between the support frame 3 and the crossbeam 13 is at its maximum. The sliding frame 4 located at the top of the support frame 3 faces the window 12. At this time, the sliding frame 4 can be pulled out from the window 12.

[0061] (2) The worker pulls the sliding frame 4 out of the window 12 in a horizontal direction. After the sliding frame 4 is pulled out of the window 12, the protective plate 5 laid on the sliding frame 4 is located on the side of the bed body 1. During the process of pulling the sliding frame 4 out of the window 12, the first square column 311 slides relative to the first sliding hole 41, and the second square column 312 slides relative to the second sliding hole 42.

[0062] (3) The worker stands on the side of the bed body 1 to replace the protective plate 5 on the sliding frame 4.

[0063] (4) The worker pushes the sliding frame 4 in the reverse direction to reset the sliding frame 4; the worker then pushes the pull rod 32 in the reverse direction to reset the support frame body 31 to the state of abutting the side of the crossbeam 13, so that the replaced protective plate 5 can cover the crossbeam 13 again, restoring the original state. Figures 2 to 5 The state shown.

[0064] (5) The above steps (1)-(4) are steps to replace the protective plate 5 above a certain crossbeam 13. The crossbeam 13 is temporarily not protected by the protective plate 5, but other crossbeams 13 are still protected by the protective plate 5. Therefore, during the cutting operation, the plate to be cut can be placed on the sword grid module 11 above the crossbeam 13 protected by the protective plate 5. This will not delay the laser cutting operation, but also protect the crossbeam 13 that is not protected by the protective plate 5.

[0065] Based on the working principle described above in this embodiment, it can be seen that this embodiment has the following effects:

[0066] First, the parallelogram mechanism 2, support frame 3, and sliding frame 4 allow the protective plate 5, which protects the crossbeam 13, to be moved out from the window 12 on the side of the bed body 1 by sequentially pulling the support frame 2 and the sliding frame 4, making the operation simple. Because the protective plate 5 is moved out from the window 12 on the side of the bed body 1, it is convenient for workers to replace the protective plate 5 from the side of the bed body 1 without stopping the machine or removing the sword grid module 11 laid on top of the bed body 1. At this time, the laser cutting machine can normally cut the plate placed on the sword grid module 11 without hindering the laser cutting operation, which helps to improve the efficiency of the laser cutting operation.

[0067] Secondly, the pull rod 32 on the support frame body 31 makes it convenient for workers to pull the pull rod 32 from the window 12, which helps to improve the ease of operation.

[0068] Third, the arrangement of the first sliding hole 41, the second sliding hole 42, the first square post 311 and the second square post 312 can limit the sliding distance of the sliding frame 4 relative to the support frame 3, prevent the sliding frame 4 from slipping off the support frame 3, and help improve the assembly reliability of the sliding frame 4 and the support frame 3.

[0069] Further, see Figure 6 The support frame body 31 has a groove on the side facing the crossbeam 13. A magnetic element is provided in the groove. The magnetic element can be a magnet 313. The magnet 313 is fixed in the groove with screws. The magnet 313 can be attracted to the side of the carbon steel crossbeam 13.

[0070] When the distance between the support frame body 31 and the crossbeam 13 is at its minimum, the magnet 313 on the side of the support frame body 31 can be attracted to the side of the crossbeam 13, which can improve the stability of the support frame body 31, and consequently improve the stability and reliability of the protective plate 5 covering the crossbeam 13.

[0071] Further, see Figure 7 and Figure 8 The sliding frame 4 has multiple positioning holes 43 along its horizontal direction. (See also...) Figure 9 The bottom of the protective plate 5 is provided with a positioning boss 51, and the protective plate 5 and the positioning boss 51 are an integral structure. See also Figure 10 When the positioning boss 51 is located inside the positioning hole 43, the positioning boss 51 can be limited by the positioning hole 43, preventing the protective plate 5 from moving in the plane, which helps to improve the stability of the protective plate 5 placed on the sliding frame 4.

[0072] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
