[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0027] See Figure 1 and Figure 2 This embodiment provides a laser cutting table for sheet metal, comprising:

[0028] The support frame 1 has a positioning baffle 2 fixedly installed at one end. The positioning baffle 2 is used to position the feeding position of one end of the sheet metal part. When feeding, the one end of the sheet metal part is attached to the positioning baffle 2 for feeding.

[0029] The position adjustment roller 3 is provided in multiple sets within the support frame 1;

[0030] Support plate 4 is configured to lift within support frame 1. Multiple sets of support plate 4 are provided, and support plate 4 and position adjustment roller 3 are arranged at intervals.

[0031] The position adjustment roller 3 is used to adjust the position of the sheet metal parts placed on it, and the support plate 4 is used to support the sheet metal parts. The support plate 4 is configured to adjust the relative height between its upper surface and the upper surface of the position adjustment roller 3 by lifting and lowering.

[0032] During operation, in the initial state, the height of the position adjusting roller 3 is higher than that of the support plate 4. The sheet metal part is fed manually or by an automatic feeding system. During feeding, one end of the sheet metal part is attached to the positioning baffle 2 to limit the feeding position of the sheet metal part in the length direction. After the sheet metal part is fed, if there is a deviation in the feeding position in the width direction, the position of the sheet metal part can be quickly adjusted by controlling the rotation of the position adjusting roller 3. After the position adjustment is completed, the support plate 4 is raised so that the height of the upper surface of the support plate 4 is higher than the height of the upper surface of the position adjusting roller 3. At this time, the sheet metal part is stably supported by the support plate 4 to ensure the stability of the sheet metal part during laser cutting.

[0033] It should be noted that in this embodiment, multiple sets of position adjusting rollers 3 are driven to rotate synchronously by a set of motors. The multiple sets of position adjusting rollers 3 can be connected by chain transmission. The principle of synchronous rotation can be referred to that of a roller conveyor. Since it is existing technology, its specific structure and working principle will not be described in detail in this solution.

[0034] Specifically, see Figure 4 and Figure 5In this embodiment, a laser cutting table for sheet metal also includes a height adjustment mechanism. The height adjustment mechanism includes a height adjustment motor 5 and a height adjustment assembly. The output end of the height adjustment motor 5 is fixedly provided with a drive gear 6. Multiple sets of height adjustment assemblies are provided corresponding to the support plate 4. A driven gear 7 is fixedly provided on one set of height adjustment assemblies. The driven gear 7 meshes with the drive gear 6. Adjacent sets of height adjustment assemblies are connected by a transmission chain 8.

[0035] During operation, the height adjustment motor 5 drives the drive gear 6 to rotate. Through the meshing of the drive gear 6 and the driven gear 7, a set of height adjustment components are driven to move. Under the action of the transmission chain 8, multiple sets of height adjustment components are driven to move. The multiple sets of height adjustment components drive the corresponding support plate 4 to rise or fall respectively. Specifically, when the height adjustment motor 5 rotates forward, the height adjustment components drive the support plate 4 to rise. When the height adjustment motor 5 rotates in reverse, the height adjustment components drive the support plate 4 to fall.

[0036] Specifically, see Figures 3-6 In this embodiment, the height adjustment assembly includes a nut sleeve 9, a threaded rod 10, a guide cylinder 11, and a guide rod 12. The nut sleeve 9 is rotatably mounted, the threaded rod 10 is connected to the nut sleeve 9 by threads, the guide cylinder 11 is fixedly mounted, and the guide rod 12 is slidably mounted inside the guide cylinder 11. The support plate 4 is connected to the threaded rod 10 and the guide rod 12. The driven gear 7 is fixedly mounted on the nut sleeve 9 of a set of height adjustment assemblies. A set of sprockets is provided on each of the two adjacent sets of nut sleeves 9. The two ends of the transmission chain 8 are sleeved on the sprockets of the two adjacent sets of nut sleeves 9 and mesh with the sprockets.

[0037] During operation, when the height adjustment motor 5 drives the nut cylinder 9 to rotate, the nut cylinder 9 drives the threaded rod 10 to rise and fall, and the guide rod 12 slides and rises and falls along the guide cylinder 11. Under the driving force of the threaded rod 10 and the guiding force of the guide rod 12, the support plate 4 is driven to rise and fall.

[0038] Specifically, see Figures 1-3 In this embodiment, a set of position adjustment slots 13 are respectively provided on the opposite side walls of the support frame 1. A position adjustment mechanism is provided in the position adjustment slots 13. The position adjustment mechanism includes a position adjustment motor 14, a position adjustment screw 15, a position adjustment slide rod 16, and a position adjustment frame 17. The position adjustment motor 14 is fixedly installed on the side wall of the support frame 1. The position adjustment screw 15 is rotatably installed in one set of position adjustment slots 13. One end of the position adjustment screw 15 is fixedly connected to the output end of the position adjustment motor 14. The position adjustment slide rod 16 is fixedly installed in another set of position adjustment slots 13. A position adjustment nut block 18 is threadedly connected to the position adjustment screw 15. A position adjustment slider 19 is slidably installed on the position adjustment slide rod 16. The two ends of the position adjustment frame 17 are respectively connected to the position adjustment nut block 18 and the position adjustment slider 19.

[0039] During operation, the position adjustment motor 14 is started, which drives the position adjustment screw 15 to rotate. Under the drive of the position adjustment screw 15 and the guidance of the position adjustment slide 16, the position adjustment frame 17 is driven to adjust its position on the support frame 1, that is, the position of the support frame 1 relative to the positioning baffle 2 is adjusted so that the distance between the position adjustment frame 17 and the positioning baffle 2 is adapted to the length of the sheet metal part.

[0040] Specifically, see Figure 1 and Figure 3 In this embodiment, a set of positioning drive motors 20 are fixedly installed on both the position adjustment frame 17 and the positioning baffle 2. A drive cavity 21 is opened in both the position adjustment frame 17 and the positioning baffle 2. A bidirectional screw 22 is rotatably installed in the drive cavity 21. One end of the bidirectional screw 22 is connected to the output end of the positioning drive motor 20. A guide groove 23 is opened on the side wall of the drive cavity 21. Two sets of positioning mechanisms are respectively connected to the two ends of the bidirectional screw 22 by threads. The positioning mechanisms are slidably installed in the guide groove 23.

[0041] During operation, the bidirectional screw 22 is driven to rotate by the positioning drive motor 20. The bidirectional screw 22 drives two sets of positioning mechanisms to move. The two sets of positioning mechanisms move along the width direction of the sheet metal part to adjust the position of the positioning mechanism and avoid the positioning mechanism affecting the laser cutting machine to cut the sheet metal part at different positions. During cutting, the positioning mechanism fixes the sheet metal part to ensure the stability of the sheet metal part during laser cutting.

[0042] Specifically, see Figure 3 In this embodiment, the positioning mechanism includes a positioning block 24, an electric telescopic rod 25, and a positioning pressure plate 26. The positioning block 24 is connected to the bidirectional screw 22 by a thread. The electric telescopic rod 25 is disposed on the positioning block 24, and the positioning pressure plate 26 is connected to the free end of the electric telescopic rod 25.

[0043] During operation, the positioning mechanism is driven to the position where the sheet metal part does not need to be laser cut under the action of the bidirectional screw 22. The electric telescopic rod 25 extends to drive the positioning pressure plate 26 to press onto the sheet metal part and fix the sheet metal part.

[0044] The working principle of a laser cutting table for sheet metal provided in this embodiment is as follows:

[0045] (1) Sheet metal parts are fed manually or by an automatic feeding system. When feeding, one wide edge of the sheet metal part is attached to the positioning baffle 2. The positioning baffle 2 limits the feeding position of the sheet metal part in the length direction. After feeding, if the feeding position of the sheet metal part in the width direction is deviated, the position adjustment roller 3 can be started to rotate. The position adjustment roller 3 can quickly adjust the feeding position of the sheet metal part.

[0046] (2) After the adjustment is completed, the support plate 4 is driven to rise under the action of the height adjustment mechanism. When the upper surface of the support plate 4 is higher than the position adjustment roller 3, multiple sets of support plates 4 cooperate to provide stable support for the sheet metal parts.

[0047] (3) Adjust the position of the position adjustment frame 17 under the action of the position adjustment mechanism. When the position adjustment frame 17 moves to the other wide side of the sheet metal part, start the positioning mechanism on the position adjustment frame 17 and the positioning baffle 2 to stably press the sheet metal part to ensure the stability of the sheet metal part when cutting. And when cutting, the bidirectional screw 22 can be driven to rotate by the positioning drive motor 20 to adjust the position of the two sets of positioning mechanisms to avoid the positioning mechanism affecting the cutting position of the cutting mechanism on the sheet metal part.
