[0028] Embodiment 1

[0029] Reference Figure 1 The utility model discloses a frame structure of a laser cutting machine, including a workbench 1, a plurality of supporting rack plates 2 and a spacing adjustment component 3. A guide rail 4 is arranged in the workbench 1, and the plurality of supporting rack plates 2 are installed on the spacing adjustment component 3. Each supporting rack plate 2 is slidably connected to the guide rail 4 through a corresponding fixing member 5.

[0030] With the above structure, when laser cutting is required for different objects, a plurality of support rack plates 2 are adjusted through the spacing adjustment component 3, so that the spacing between two adjacent support rack plates 2 can be adjusted within a certain range, and the adjustment is convenient.

[0031] In detail, in this embodiment, a collecting groove 6 is provided on the top of the workbench 1, and the collecting groove 6 is used to collect waste generated during the laser cutting process. The inner cavity walls of the collecting groove 6 are fixed with guide rails 4 by bolts, and the guide rails 4 provide fixing members 5 to drive each supporting rack plate 2 to slide smoothly horizontally.

[0032] Reference Figure 2 In detail, in the present embodiment, the fixing member 5 comprises a support plate 501, at both ends of which are fixed raised sliders 505 slidably connected to the guide rail 4, a top of the support plate 501 is provided with an embedding groove 502, a side wall of the support plate 501 is provided with a locking hole 503, a locking bolt 504 is screwed in the locking hole 503, one end of the locking bolt 504 located in the embedding groove 502 abuts against the side surface of the support rack plate 2, and the support plate 501 is used as a support, and the support rack plate 2 can be fixed in the embedding groove 502 by the locking bolt 504, which is convenient for disassembly and replacement of the support rack plate 2, and the support rack plate 2 is slidably connected to the guide rail 4 through the support plate 501, which is convenient for adjustment of the support rack plate 2 when the spacing adjustment component 3 adjusts the support plate 501.

[0033] In this embodiment, the spacing adjustment component 3 includes a first connecting rod 301 and a second connecting rod 302. The bottoms of the two adjacent support plates 501 are correspondingly plugged with a first support shaft 303 and a second support shaft 304. One end of the first connecting rod 301 is rotated on the outside of the first support shaft 303, and the other end of the first connecting rod 301 is connected to one end of the second connecting rod 302 through a hinge shaft 305. The other end of the second connecting rod 302 is connected to the outside of the second support shaft 304. Figure 3-Figure 4 As shown, multiple support plates 501 are alternately connected through the first connecting rod 301 and the second connecting rod 302 in sequence. The rotation of the first connecting rod 301 and the second connecting rod 302 with the hinge shaft 305 will drive the multiple support plates 502 to move closer to or away from each other, so as to achieve synchronous adjustment of the spacing of multiple supporting rack plates 2.

[0034] Reference Figure 1 and Figure 3 In detail, in this embodiment, a control groove 7 is opened on one side of the inner cavity of the workbench 1, and one end of the first connecting rod 301 or the second connecting rod 302 connected to the bottom of one side support plate 501 extends into the control groove 7, and the end extending into the control groove 7 is the control end. By adjusting this end, the first connecting rod 301 and the second connecting rod 302 connected alternately in sequence can drive multiple support plates 502 to move closer to or away from each other. A manipulator 8 is installed on the top of the workbench 1, and the output end of the manipulator 8 controls the first connecting rod 301 or the second connecting rod 302 to move closer to or away from each other. One end of the second connecting rod 302 rotates a certain angle, and the manipulator 8 can be a knob, a motor or a telescopic cylinder. When it is a knob or a motor, the rotating shaft of the knob or the motor drives one end of the first connecting rod 301 or the second connecting rod 302 to rotate clockwise or counterclockwise by a certain angle, so that the spacing of multiple supporting rack plates 2 can be adjusted; when it is a telescopic cylinder, the telescopic cylinder hinged to the workbench 1 and one end of the first connecting rod 301 or the second connecting rod 302 is extended or shortened, so that the spacing of multiple supporting rack plates 2 can be adjusted.

[0035] Working principle: When laser cutting objects of different sizes, according to the size of the object, the manipulator 8 controls one end of the first connecting rod 301 or the second connecting rod 302 to rotate a certain angle. Since multiple support plates 501 are alternately connected through the first connecting rod 301 and the second connecting rod 302 in turn, the first connecting rod 301 and the second connecting rod 302 will rotate with the hinge shaft 305, driving the multiple support plates 502 to move closer to or away from each other, so as to achieve synchronous adjustment of the spacing of multiple support rack plates 2, which is convenient to adjust, improves the operating efficiency of laser cutting work, and reduces labor intensity. The support rack plate 2 is fixed in the embedded groove 502 of the support plate 501 through the locking bolt 504, so as to disassemble and replace the support rack plate 2.

[0036] Embodiment 2

Before the object to be cut is placed on the multiple support rack plates 2, the scale 9 is used to calibrate the range of the multiple support rack plates 2 after adjustment to be suitable for the size of the object to be cut, so that the multiple support rack plates 2 can support objects of different sizes when laser cutting is performed, so that the bottom of the object is evenly stressed, and the problem of unstable support of the object is avoided when the range of the multiple support rack plates 2 after adjustment is greater than or less than the size of the object to be cut.

[0038] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
