[0002] A laser cutting machine is a device that uses a laser beam to cut materials. It heats the material to a melted or vaporized state through the high energy density of the laser beam, and then uses a high-pressure airflow to blow away the melted material, thereby achieving the cutting effect.

[0003] The door of the laser cutting machine equipment shell generally adopts PLC-controlled cylinder to drive the cylinder single door to lift and lower. The overall lifting process takes up a large space, and after the cylinder controls the single door to open, it needs to maintain a certain internal air pressure at all times when it is in the retracted or extended state to ensure the stability of the door panel, and the operation is more complicated. Therefore, a laser cutting machine linkage upper and lower double door structure is urgently needed. Utility Model Content

[0004] In response to the shortcomings of the existing technology, this solution provides a linked upper and lower double-door structure for a laser cutting machine to solve the problem that after the cylinder controls the opening of a single door, it needs to maintain a certain internal air pressure at all times when it is in a retracted or extended state to ensure the stability of the door panel, making the operation more complicated.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Combine Figures 1-4 As shown, the utility model provides: a laser cutting machine linkage type upper and lower double door structure, including a door panel 1 and a door panel 2 movably mounted on the laser cutting machine housing, a cylinder 6 is provided at both ends of the door panel 2, and the cylinder 6 is welded to the inner wall of the laser cutting machine housing, and the output shaft of the cylinder 6 is connected with a connecting seat, and the connecting seat is welded to one end of the door panel 2, so that the cylinder 6 can drive the door panel 2 2 to move downward, and a limit assembly 3 for positioning and guiding is symmetrically installed on the door panel 1 and the door panel 2, and a linkage unit 4 is installed at both ends of the door panel 1 and the door panel 2, and the linkage unit 4 includes two I-shaped guide wheels 401 rotatably mounted on the inner wall of the upper end of the laser cutting machine housing, which is used to reverse the lifting rope 402 and reduce the lifting rope 402 during operation. 02's friction force, the two guide wheels 401 are provided with a lifting rope 402 made of a nylon rope with a diameter of 3 cm, and the two ends of the lifting rope 402 are respectively fixed to one end of the inner side of the two door panels. When the cylinder 6 drives the door panel 2 2 to move downward, the lower end of the lifting rope 402 will follow and move downward. At this time, the other end of the lifting rope 402 will pull the door panel 1 upward, thereby separating the door panel 1 and the door panel 2 2 to open the laser cutting machine shell door. Since the door panel 1 and the door panel 2 2 are connected by the lifting rope 402 and serve as counterweights to each other, the pressure of the cylinder 6 when driving the door panel 2 2 to move downward is smaller. At the same time, when the door panel 1 and the door panel 2 2 are separated, the pressure inside the cylinder 6 to maintain the separation state is smaller, and the movement of the cylinder 6 is safer and more stable.

[0023] In order to ensure the stability of door panel 1 and door panel 2 when they move on the inner wall of the laser cutting machine shell, the limiting assembly 3 includes two guide plates 301 welded on the inner wall of the laser cutting machine shell, the guide plates 301 are attached to the surfaces of door panel 1 and door panel 2, and a guide groove is provided on the surface of the guide ring. A rotating seat 302 is installed in the guide groove. The rotating seat 302 is rotatably installed on the inner side surface of door panel 1 or door panel 2, and a roller 303 is rotatably installed on the side surface of one end of the guide plate 301. The roller 303 abuts on the inner side surface of door panel 1 or door panel 2. When the guide groove moves, the rotating seat 302 rotatably installed on door panel 1 can rotate in the guide groove and move with door panel 1, reducing friction while preventing the door panel 1 from shifting, and the roller 303 always rolls and abuts on door panel 1, causing the door panel 1 to shift in the longitudinal direction.

[0024] In order to facilitate the understanding of the closing status of door panel 1 and door panel 2, a detection unit 5 is installed between door panel 1 and door panel 2. The detection unit 5 of this scheme includes a travel switch welded to the inner side surface of the lower end of door panel 1 and a contact block welded to the inner side surface of the upper end of door panel 2.

[0025] The control method of the present invention is automatic control through a PLC controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.

[0026] It should be noted that, in this document, terms such as "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements that are inherent to such process, method, article or apparatus.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
