Obviously, the embodiments described in the following are only some embodiments of the present application, but not all the embodiments. Based on the embodiments in the present patent, all other embodiments obtained by those skilled in the art without creative labor are within the scope of the present patent. DETAILED DESCRIPTION
[0034] As Figure 1 and Figure 2As shown, the specific embodiment provides a large surrounding structure of a single table laser cutting machine, including a support frame, a line rail 5, a left front door and a right front door; the support frame is spliced with sheet metal 17 outside, the support frame includes two oppositely arranged support columns 1, the support columns 1 are arranged near the end of the cutting platform 18, and a cross beam 7 is arranged between the two support columns 1; the left front door and the right front door each include door body one 2 and door body two 4 hinged by a fixed hinge 3, the door body one 2 is rotatably connected with the corresponding support column 1 through the hinge, and the door body two 4 is slidably and rotatably connected with the guide rail 6 on the corresponding cross beam 7; the line rail 5 is arranged at the lower part of the cutting platform 18, and the door body two 4 is slidably and rotatably connected with the line rail 5.
[0035] The specific embodiment sets two folding doors which can be pushed and pulled on the large surrounding structure, compared with the lifting door, greatly widens the width of the large surrounding structure allowing the plate to enter and exit, occupies small space, and is convenient for forklift and other feeding equipment to feed, meets the processing requirements of plate with larger size range; meanwhile, the upper and lower ends of the door body two 4 are each provided with a corresponding guide structure, which improves the stability of the opening and closing of the door body two 4 and avoids jamming.
[0036] In the specific embodiment, the upper and lower ends of the door body two 4 are each rotatably provided with a connecting plate 9, the end of the connecting plate 9 is connected with a corresponding sliding block 12, the upper sliding block 12 is movably arranged on the guide rail 6 of the cross beam 7, and the lower sliding block 12 is movably arranged on the line rail 5; specifically, a reinforcing column is vertically arranged on the opening and closing side of the inner surface of the door body two 4, the upper and lower ends of the reinforcing column are each provided with a hinge seat 10, the hinge seat 10 is rotatably connected with the connecting plate 9 through a pin shaft, and the other end of the connecting plate 9 is connected with the corresponding sliding block 12 through a bolt.
[0037] Further, in order to facilitate the feeding and discharging equipment to enter and exit the large enclosure structure, the middle part of the cross beam 7 is provided with an avoiding opening 8, which can avoid interference with the feeding and discharging equipment. In order to avoid the sliding block 12 from being separated from the avoiding opening 8 of the cross beam 7, the connecting plate 9 located at the upper end of the door body two 4 is in an L-shaped structure, which includes a connecting part one 901 and a connecting part two 902. The connecting part one 901 protrudes from the plane of the cross beam 7, and the connecting part two 902 extends in the direction of the door body one 2.

Further, a handle 13 is arranged on the door body one 2, and the handle 13 is arranged close to the door body two 4, so that the door can be opened more labor-savingly.
[0041] In order to further improve the sealing, the edges of the door body one 2 and the door body two 4 are provided with sealing strips, and the linear rail 5 is provided with a light shield plate on the side close to the cutting platform 18; the sealing strips effectively prevent the smoke in the large enclosure from leaking and polluting the environment, the light shield plate avoids light leakage and spark leakage, and the safety is improved.
[0042] Since some pipelines are fed from the top through a travelling crane and the like, in order to adapt the large enclosure structure to the feeding mode from the top, improve the use flexibility, in the embodiment, two top covers 15 are further included, which are movably arranged on the top of the support frame, and the opposite ends of the two top covers 15 can be attached when closed; specifically, the top of the support frame is provided with a sliding rail assembly, the top cover 15 is connected with the sliding block 12 of the sliding rail assembly, the other end of the top cover 15 is provided with a pneumatic cylinder 16, the pneumatic cylinder 16 is arranged on the sheet metal 17 on the top, and the pneumatic cylinder 16 drives the top rod to approach and move away, thereby realizing the opening and closing of the top.
[0043] In order to facilitate the maintenance of the laser processing equipment, in the embodiment, a maintenance door is further included, which is arranged opposite to the door body one 2 and / or the door body two 4, and is rotatably arranged on the rear upright column of the support frame through a hinge; in the embodiment, the maintenance door is arranged opposite to the door body one 2 and the door body two 4.
