[0027] Please see Figures 1 to 6The present invention provides an embodiment of a laser cutting machine protective device, which includes a laser cutting machine body 1, a support frame 2, a movable frame 3, fixing parts 4, a bellows cover 5, and mounting parts 6. The support frame 2 moves horizontally along the Y-axis of the laser cutting machine body 1, and the movable frame 3 moves horizontally along the X-axis of the laser cutting machine body 1. The support frame 2 is located at the top of the laser cutting machine body 1, and the movable frame 3 is located at the top of the support frame 2. The fixing parts 4 are distributed on both sides of the movable frame 3, and there are four sets of fixing parts 4. The bellows cover 5 is located between two sets of fixing parts 4, and the mounting parts 6 are distributed at one end of any set of fixing parts 4.

[0028] The main body 1 of the laser cutting machine is the base of the entire equipment. The support frame 2 moves horizontally along the Y-axis and supports the movable frame 3, which is responsible for positioning the laser cutting head in the Y-axis direction. The movable frame 3 moves horizontally along the X-axis and the laser cutting head is installed at the bottom, which is responsible for positioning in the X-axis direction. The bellows protective cover 5 is the core protective component, which isolates the waste chips, sparks and strong light generated by cutting and protects the operators. It adopts a "bellows" folding structure to adapt to the dynamic movement of the movable frame 3.

[0029] Mounting component 6 includes a support frame 61, a rotating column 62, a connecting frame 67, and a mounting column 68; the surfaces of the two sets of support frames 61 located on the inner side are fixed to the surface of the movable frame 3, the rotating column 62 is rotatably connected to the inside of the support frame 61, the connecting frame 67 is distributed on the outside of the rotating column 62 at one end away from the support frame 61, and the mounting column 68 is fixed to the outer surface of the connecting frame 67.

[0030] The support frame 61 is used to support and install the rotating column 62. By changing the state of the rotating column 62, and cooperating with the movement of the limit block 66, the mounting plate 42 can be locked and unlocked. The connecting frame 67 is linked with the rotating column 62 and is locked by the limit block 66. The mounting column 68 is used to fix the connecting frame 67 inside the top of the mounting plate 42.

[0031] A spring 63 is fixed inside the rotating column 62, and a connecting column 64 is fixed on the surface of the spring 63.

[0032] The spring 63 provides elastic force after compression, so that the limit block 66 automatically resets and locks. The connecting post 64 is used to connect the spring 63 and the guide plate 65 together.

[0033] A guide plate 65 is fixed to the surface of the connecting column 64, and a limit block 66 is fixed to the surface of the guide plate 65. The limit block 66 is inserted into the inside of the connecting frame 67.

[0034] The guide plate 65 facilitates changing the position of the limiting block 66. After the limiting block 66 pops into the connecting frame 67, the mounting plate 42 can be locked inside the mounting frame 41.

[0035] Mounting brackets 69 are fixed to the outer surfaces of the two outer sets of support frames 61, and the surfaces of the mounting brackets 69 are fixed to the surfaces of the support frames 2;

[0036] Mounting bracket 69 is used to install the outer mounting piece 6 in the desired position;

[0037] The fastener 4 includes a mounting frame 41 and a mounting plate 42; the mounting frame 41 is fixed to the surfaces on both sides of the movable frame 3, and the mounting frame 41 is also fixed to the surfaces on both sides of the support frame 2; the mounting plate 42 is inserted into the interior of the mounting frame 41, and the interior of the mounting plate 42 near the support frame 61 is glued and fixed to the mounting column 68.

[0038] Mounting frame 41 provides guidance and limit for mounting plate 42, which is used to insert into the interior of mounting frame 41, thereby installing accordion cover 5 in the desired position;

[0039] Mounting holes 43 are provided inside the mounting frame 41, mounting plate 42 and bellows cover 5. The cross-section of the mounting hole 43 is "T" shaped and the mounting hole 43 is wider on the outside and narrower on the inside.

[0040] The "T"-shaped design of the mounting frame 41 makes it easy to store the outer side of the bolt 44 inside the mounting plate 42, preventing the outer side of the mounting plate 42 from protruding and the mounting plate 42 from being unable to be inserted into the mounting frame 41.

[0041] A bolt 44 is provided inside the mounting hole 43, and the nut of the bolt 44 is located inside the bellows cover 5;

[0042] Bolt 44 is used to securely connect the bellows cover 5 and the mounting plate 42 together;

[0043] Working principle: When the main body 1 of the laser cutting machine is working, the support frame 2 moves the movable frame 3 to the required position under the action of the drive component. Then, under the action of the drive component, the laser cutting head at the bottom of the movable frame 3 moves to the required position. During the cutting process, the waste chips and strong light generated can be effectively protected by the design of the bellows protective cover 5.

[0044] When it is necessary to disassemble or assemble the bellows cover 5, a pushing force is applied to the guide plate 65, causing the limiting block 66 to disengage from the interior of the connecting frame 67. Then, a rotational force is applied to the guide plate 65, so that the rotating column 62 is in a vertical state. After the connecting frame 67 is unrestricted, an upward pulling force is applied to the bellows cover 5, so that the mounting plate 42 disengages from the interior of the mounting frame 41. After removing the bolt 44 from the interior of the bellows cover 5, the new bellows cover 5 is connected to the mounting plate 42 by the bolt 44. After inserting the mounting plate 42 into the interior of the mounting frame 41, a pressing force is applied to the guide plate 65. After the spring 63 is in a compressed state, a flipping force is applied to the guide plate 65, so that the rotating column 62 is in a horizontal state. Then, the force applied to the guide plate 65 is released. Under the elastic force of the spring 63, the limiting block 66 springs into the interior of the connecting frame 67.

[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
