Description

Technical Field

[0001] This utility model relates to, but is not limited to, the field of laser cutting equipment support technology. Specifically, it relates to a laser cutting equipment support platform for laser cutting. Background Technology

[0002] A laser cutting machine uses a laser beam emitted from a laser source. The laser beam is focused into a high-power-density laser beam through an optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach its melting or boiling point. At the same time, high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, a kerf is eventually formed in the material, thus achieving the purpose of cutting.

[0003] In existing technologies, when using a laser cutting machine to cut a workpiece, the laser cutting machine is typically mounted above a support worktable. The workpiece to be cut is placed on the cutting grid plate of the support worktable, and the position of the laser cutting machine is adjusted by moving it to cut the workpiece as needed. However, the support table is fixed and cannot be adjusted. For extra-long materials, an auxiliary table must be temporarily added or the entire support table must be replaced, making the process cumbersome. Therefore, this paper proposes a laser cutting equipment support table with an expandable table surface. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a support platform for laser cutting equipment.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: This utility model discloses a support platform for laser cutting equipment, including a main body of the support platform. The main body of the support platform includes two support frames, a cutting mesh plate located between the two support frames, and a base plate disposed at the bottom of the support frames. Two cutting mesh plate extension components are disposed on the bottom side of the cutting mesh plate. Each cutting mesh plate extension component includes an extension panel, a support member, a folding member, and a connecting hinge for connecting the extension panel and the cutting mesh plate. The support member is disposed on the bottom side of the extension panel, and the folding member is disposed between the support member and the extension panel. A debris cleaning component is mounted above the cutting mesh plate.

[0006] Preferably, the connecting hinge is disposed at the bottom of the extension panel and the cutting mesh plate, and the support includes a support rod, a connecting ear plate a and a bottom rod. The connecting ear plate a is screwed to the support rod and the extension panel respectively, and the bottom rod is welded to the support rod.

[0007] Preferably, the support rod is composed of several steel columns with successively decreasing external dimensions. The steel columns are sequentially nested in a center-corresponding structure. The bottom of the outermost steel column is welded to the support rod, and the outer thread is fitted with a limit screw. The inner steel column surface is provided with a limit hole that is threaded to the limit screw.

[0008] Preferably, the support rod is provided with folding parts on both the left and right sides. The folding parts include an upper folding rod, a lower folding rod, and a connecting ear plate b. The connecting ear plate b is screwed to the upper folding rod and the expansion panel, respectively. The two ends of the lower folding rod are screwed to the upper folding rod and the support rod, respectively.

[0009] Preferably, the debris cleaning assembly includes a mounting frame, a push rod, a cleaning plate, and a movable component. The mounting frame has an inverted "U" shape. The push rod is located between the mounting frame and the cleaning plate. The cleaning plate is positioned directly above the cutting mesh plate. The movable component is located between the mounting frame and the support frame.

[0010] Preferably, at least three push rods are provided above the cleaning plate. The push rods are one of electric push rods, telescopic rods, or a combination of electric push rods and telescopic rods, and at least one electric push rod is included.

[0011] Preferably, the bottom surface of the cleaning plate is provided with a brush or a cone.

[0012] Preferably, the moving component includes a rotary motor, a lead screw, and a slider. The rotary motor is mounted on one side of the support frame, the lead screw is located at the output end of the rotary motor, and the slider is sleeved on the outside of the lead screw and screwed to the mounting frame.

[0013] Preferably, the top of the support frame has a movable groove for moving the slider, the lead screw is placed inside the movable groove, the output end of the rotary motor is connected to the lead screw for transmission, and the lead screw is threadedly engaged with the slider.

[0014] Preferably, the cutting mesh plate is screwed to the support frames on the left and right sides, the base plate has a concave design, and the support frames are screwed to the base plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention provides a cutting mesh plate extension assembly on the bottom side of the cutting mesh plate, consisting of an extension panel, connecting hinges, steel column support, and folding components. The extension panel can be flipped down to unfold or folded up to store by simply loosening the screws of the folding components, lowering the extension panel, and pulling out the steel column to lock it. This expands the supporting working surface without the need for an external auxiliary table. After cutting, the extension panel is folded back and locked, and then returned to the bottom of the cutting mesh plate without occupying extra space. This solves the problem of fixed and unadjustable support tables, which necessitates the temporary addition of auxiliary tables or complete replacement when encountering extra-long plates, resulting in a cumbersome process.

[0019] like Figure 1-6 As shown, this utility model provides a support platform for laser cutting equipment, including a main body 1. The main body 1 includes two support frames 11, a cutting screen 12 located between the two support frames 11, and a base plate 13 disposed at the bottom of the support frames 11. Two cutting screen extension components 2 are disposed on the bottom side of the cutting screen 12. The cutting screen extension component 2 includes an extension panel 21, a support member, a folding member, and a connecting hinge 29 for connecting the extension panel 21 and the cutting screen 12. The support member is disposed on the bottom side of the extension panel 21, and the folding member is disposed between the support member and the extension panel 21. A debris cleaning component 3 is mounted on the top of the cutting screen 12.

[0020] Furthermore, in this embodiment, the connecting hinge 29 is disposed at the bottom of the extension panel 21 and the cutting mesh plate 12. The connecting hinge 29 enables the extension panel 21 and the cutting mesh plate 12 to be hinged, allowing the extension panel 21 to be flipped down to unfold or folded up to store, while maintaining structural stability. The support component includes a support rod 22, a connecting ear plate a23 and a bottom rod 24. The connecting ear plate a23 is screwed to the support rod 22 and the extension panel 21 respectively. The bottom rod 24 is welded to the support rod 22. The connecting ear plate a23 is used to connect the support rod 22 and the extension panel 21, and the bottom rod 24 supports the support rod 22.

[0021] In this embodiment, the support rod 22 is composed of several steel columns (not shown in the figure) with successively decreasing external dimensions. The steel columns are sequentially nested in a center-corresponding structure. The bottom of the outermost steel column is welded to the support rod 22. The support height of the extension panel 21 can be adjusted by pulling out steel columns of different diameters. The outer threads are fitted with limit screws 25, and the inner steel column surfaces are provided with limit holes that are threaded with the limit screws 25. The limit screws 25 and the limit holes are used to lock the extension and retraction positions of the steel columns to prevent slippage and ensure support rigidity.

[0022] It should be noted that the material of the steel column and the selection of the limit screw 25 must ensure that the steel column can withstand the weight of the material above when it extends, and that the limit screw 25 is strong enough to support the weight of the material above.

[0023] In this embodiment, folding components are provided on both the left and right sides of the support rod 22. The folding components include an upper folding rod 26, a lower folding rod 27, and a connecting ear plate b28. The connecting ear plate b28 is screwed to the upper folding rod 26 and the extension panel 21 respectively. The folding rod is installed through the connecting ear plate b28. The two ends of the lower folding rod 27 are screwed to the upper folding rod 26 and the support rod 22 respectively. The lower folding rod 27 is located on the outer side near the bottom of the support rod 22. The upper folding rod 26 can rotate on the connecting ear plate b28 and the lower folding rod 27 through the screw connection. The lower folding rod 27 can rotate on the outer side of the upper connecting rod and the support rod 22, so that the screws can be loosened to fold the folding components and store the support components.

[0024] Specifically, after loosening the screws, the upper folding rod 26 can rotate around the connecting ear plate b28, and the lower folding rod 27 can rotate around the support rod 22, so that the extension panel 21 is folded and placed on the bottom side of the cutting mesh plate 12, and the screws of the support rod 22 and the connecting ear plate a23 are loosened, reducing space occupation. When the support is unfolded, tighten all screws. The folding rod and the support rod 22 form a triangular support structure, which enhances the load-bearing stability of the extended panel 21.

[0025] It should be noted that the screws need to be tightened after the folding parts are folded and unfolded. The screws can be removed before folding, or they can be loosened before folding.

[0026] In this embodiment, the debris cleaning assembly 3 includes a mounting frame 31, a push rod 32, a cleaning plate 33, and a movable component. The mounting frame 31 has an inverted "U" shape design, which allows the mounting frame 31 to span the cutting mesh plate 12, providing mounting fulcrums for the push rod 32 and the cleaning plate 33, ensuring that the cleaning mechanism covers the entire mesh plate area. The push rod 32 is disposed between the mounting frame 31 and the cleaning plate 33, and the cleaning plate 33 is positioned directly above the cutting mesh plate 12. The movable component is disposed between the mounting frame 31 and the support frame 11.

[0027] In this embodiment, at least three push rods 32 are provided above the cleaning plate 33. The push rods 32 are one of electric push rods 32, telescopic rods, or a combination of electric push rods 32 and telescopic rods, and at least one electric push rod 32 is included.

[0028] Specifically, the push rod 32 consists of three electric push rods 32, which extend and retract simultaneously to control the cleaning plate 33 to move toward the cutting mesh plate 12. The push rod 32 consists of one electric push rod 32 and two telescopic rods. The telescopic rods are located on the left and right sides of the electric push rod 32 and are used as guides. The movement of the cleaning plate 33 is controlled by a single electric push rod 32, and the telescopic rods extend and retract simultaneously.

[0029] It should be noted that if more than one electric actuator 32 is set, the electric actuators 32 must extend and retract synchronously.

[0030] In this embodiment, the bottom surface of the cleaning plate 33 is provided with a brush or a cone. The brush removes light debris (such as metal dust) from the surface of the mesh plate, or the cone clears the mesh holes 14 of the cutting mesh plate 12 and pushes out the heavy molten slag stuck in the mesh holes 14 to prevent blockage.

[0031] In this embodiment, the moving component includes a rotary motor 34, a lead screw 35, and a slider 37. The rotary motor 34 is mounted on one side of the support frame 11, the lead screw 35 is located at the output end of the rotary motor 34, and the slider 37 is sleeved on the outside of the lead screw 35 and screwed to the mounting frame 31.

[0032] In this embodiment, the top of the support frame 11 is provided with a movable groove 36 for the sliding block 37 to move. The lead screw 35 is placed inside the movable groove 36. The output end of the rotary motor 34 is connected to the lead screw 35 for transmission. The lead screw 35 is threadedly engaged with the sliding block 37. The rotary motor 34 drives the lead screw 35 to rotate, and the lead screw 35 pushes the sliding block 37 to move horizontally. The sliding block 37 drives the mounting frame 31 to move horizontally along the movable groove 36, so as to achieve full coverage of the cleaning plate 33.

[0033] It should be noted that, in order to avoid conflict between the debris cleaning component 3 and the laser cutting machine 4 during laser cutting, the screws of the mounting bracket 31 and the slider 37 should be loosened during laser cutting, while retaining the slider 37, the lead screw 35 and the rotary motor 34. A removable cover plate should be inserted above the movable slot 36 and sealed to prevent debris from entering the movable slot 36. The mounting bracket 31, the push rod 32 and the cleaning plate 33 can be stored away.

[0034] In this embodiment, the cutting mesh plate 12 is screwed to the support frames 11 on the left and right sides, and the base plate 13 has a concave design. The support frames 11 are screwed to the base plate 13. Through the design of the base plate 13, the debris can fall into the base plate 13 through the mesh 14 during laser cutting and cleaning, which is convenient for cleaning.

[0035] Specifically, the existing laser cutting equipment is installed on the support platform body, which can be installed on the support frame 11 or the cutting mesh plate 12. When the length of the steel plate or steel pipe to be cut exceeds the length of the cutting mesh plate 12, the cutting mesh plate extension assembly 2 is used. The screws of the folding rod are loosened, and the extension panel 21 is held with one hand. It is slowly rotated around the connecting hinge 29. The upper folding rod 26 rotates downward around the connecting ear plate b28, and the lower folding rod 27 rotates outward around the support rod 22. The support rod 22 is perpendicular to the ground until the three form a triangular support. Then, the steel columns are pulled out to the required height so that the extension panel 21 is flush with the upper surface of the cutting mesh plate 12. The limiting screws 25 are screwed into the corresponding limiting holes to fix the support height of the support rod 22. All screws are tightened to complete the triangular support structure and support the extension plate. Place the steel plate / pipe on the cutting mesh plate 12 and the extension panel 21. Confirm that the extension area support is stable. Start the laser cutting machine 4 and cut according to the process program. After the cutting is completed, remove the laser cutting machine 4. After the table cools down, install the debris cleaning component 3. Start the rotary motor 34 via remote control. The rotary motor 34 drives the lead screw 35 to rotate. The slider 37 and the mounting bracket 31 move from one end to the other at a constant speed. The push rod 32 extends to lower the cleaning plate 33. The brush gently sweeps the surface dust, or the cone is inserted into the mesh hole 14 to push out the slag. The motor rotates forward and backward 2-3 times until the mesh hole 14 is clear and the debris falls into the base plate 13. After cleaning is completed, the push rod 32 retracts and the cleaning plate 33 rises to the highest position. The rotary motor 34 moves the mounting bracket 31 to the initial end. If there is stubborn slag, use a pry bar to gently tap it from above the mesh plate to make it fall into the base plate 13. Pull out the base plate 13, empty the debris, clean it, and reinstall it. Disassemble the cleaning assembly, disconnect the screws of the mounting bracket 31 and the slider 37, remove the cleaning assembly, reinsert the cover plate of the movable slot 36 and seal it, loosen all the screws of the folding part, retract the upper and lower folding rods 27, unscrew the limit screws 25, retract the steel column completely and lock it, flip the extension panel 21 upward until the bottom surface of the extension panel 21 is level with the bottom surface of the cutting panel, tighten the screws of the folding part to restrict the extension panel 21 and the support rod 22; It is important to note that the cleaning components must be completely removed and the movable groove 36 sealed during laser cutting to prevent damage from laser reflection. High-temperature grease should be sprayed regularly at the hinge of the folding parts to prevent jamming. The steel column telescopic mechanism should be inspected every two weeks for thread wear of the limit screw 25 and replaced if necessary.

[0036] It should be noted that when the cutting stencil 12 does not need to be expanded, the cutting stencil expansion assembly 2 can be disassembled to prevent debris from affecting the use of the cutting stencil expansion assembly 2.

[0037] It is worth noting that the control method in this application is to control the activation of electric components such as electric push rod 32 and rotary motor 34 through a remote control. The control circuit of the remote control can be implemented by a person skilled in the art through simple programming, which is common knowledge in the field. This application will not explain the control method and circuit connection in detail.
