It should be noted that, because the weight of the cross beam 41 and the saddle 42 is large, once the five-axis laser processing machine tool tilts or vibrates during transportation, the cross beam 41 and the saddle 42 form large kinetic energy of motion, which is easy to cause the failure of the fixing structure of the optical path transmission box 11, so as to better ensure the stability of the transportation and fixing structure of the optical path transmission box 11 and the laser box 12, the cross beam 41 is locked on the bed 10 by the first locking plate 46, and the saddle 42 is locked on the cross beam 41 by the second locking plate 47, which ensures that the cross beam 41 and the saddle 42 do not slide during transportation.

As shown in fig. 6 to 10, the first organ cover 75 expands or contracts with the up-and-down movement of the optical path transmission case 11, and in order to prevent the first organ cover 75 from being displaced and interfering with the laser inside the first organ cover when moving, the first organ cover 75 is guided by a linear guide mechanism; the linear guide mechanism comprises a mounting lug 751 arranged at the lower end of the first organ cover 75, a plurality of positioning lugs 752 are arranged on the side wall of the first organ cover 75, the mounting lug 751 and the plurality of positioning lugs 752 are arranged on the same side, an elastic mechanism 9 is arranged on the elongated protective shell 74, a pull wire 78 is arranged on the mounting lug 751, the pull wire 78 sequentially penetrates through the plurality of positioning lugs 752, the tail end of the pull wire 78 is connected with the elastic mechanism 9, and the elastic mechanism 9 is used for releasing the pull wire 78 along with the expansion of the first organ cover or tightening the pull wire 78 along with the contraction of the first organ cover.
In actual installation, the first organ cover 75 extends vertically, the pull wire 78 is pulled out from the tightening mechanism 9, and then sequentially passes through the plurality of positioning tabs 752 from top to bottom, and when passing through the positioning tab 752 at the lowermost end, one end of the pull wire 78 is bound to the installation tab 751. When the optical path transmission box body 11 moves downward, the optical path transmission box body 11 drives the first organ cover 75 to extend vertically, that is, the whole length of the first organ cover 75 is lengthened, so that the length of the stay wire 78 passing through the plurality of positioning lugs 752 also needs to be lengthened, and as the traction force of the optical path transmission box body 11 is greater than the winding tension force of the tightening mechanism 9, the tightening mechanism 9 releases the stay wire 78, and the stay wire 78 is tightened and straightened under the effect of the winding tension force, so that the stay wire 78 limits the first organ cover 75 from tilting. Conversely, when the optical path transmission box body 11 moves upward, the optical path transmission box body 11 drives the first organ cover 75 to contract vertically, that is, the overall length of the first organ cover 75 is shortened, so that the length of the pull wire 78 passing through the plurality of positioning lugs 752 also needs to be shortened, and under the rolling pulling force provided by the tightening mechanism 9, part of the pull wire 78 is automatically rolled on the tightening mechanism 9, and the pull wire 78 is stretched again, so that the pull wire 78 limits the first organ cover 75 from tilting.

The existing organ cover is improved, a mounting lug 751 is arranged at the lower end of the existing organ cover, a positioning lug 752 is arranged at each folding position of the first organ cover, the stay wire 78 sequentially passes through second through holes 7521 on the positioning lugs 752 from top to bottom, then the stay wire 78 is tied to the mounting lug 751 through the first through holes 7511 to realize the fixation of the stay wire 78, the first through holes 7511 and the second through holes 7521 which are overlapped by the center line ensure the verticality of the stay wire 78, namely, the stay wire 78 cannot be contacted with the positioning lugs 752 under the normal movement of the first organ cover 75; when the first organ cover 75 is deviated, the pull wire 78 contacts the positioning lug 752 to limit the first organ cover 75 from tilting, so that friction between the positioning lug 752 and the pull wire 78 is reduced, and the pull wire 78 is prevented from being broken.
With such an arrangement, the pulling wire 78 extends along the length direction of the elongated protective housing 74 after being pulled out from the elastic mechanism 9, in order to enable the pulling wire 78 to transition to the vertical state, the elongated protective housing 74 is provided with the pulley assembly 8 for changing the direction of the pulling wire 78, and the elongated protective housing 74 is provided with an avoiding through hole 741 for the pulling wire 78 to pass through, so that the pulling wire 78 can vertically pass through all the positioning tabs 752.

Through the guidance of the first pulley 82 and the second pulley 83, not only the moving direction of the pulling wire 78 can be changed, but also the pulling wire 78 can be prevented from being separated from the pulley assembly 8 due to the fact that the optical path transmission case 11 moves too fast, and the winding mode of the embodiment is specifically as follows: the pull wire 78 is pulled out of the tightening mechanism 9, passes through the bottom of the second pulley 83, passes through the top of the second pulley 83, sequentially passes through the escape through hole 741, the second through hole 7521 and the first through hole 7511, and is finally fixed on the mounting lug 751.
