Description

Technical Field

[0001] This utility model relates to the field of furniture manufacturing technology, specifically to a high-precision laser cutting device for intelligent furniture processing. Background Technology

[0002] With the popularization of the smart home concept and the increasing demand for personalized furniture, traditional furniture processing methods face challenges such as low precision, poor efficiency, and difficulty in meeting the processing needs of complex shapes. Laser cutting technology, with its advantages of high precision, high speed, and non-contact processing, is gradually becoming an important technological means in the field of smart furniture processing.

[0003] Laser cutting equipment typically uses a three-axis moving mechanism to drive the laser cutting head to achieve precise cutting. During cutting, the raw material is usually placed horizontally on a support grid. The support grid is usually composed of several serrated or strip-shaped steel plates arranged in parallel intervals. While supporting the material, it can effectively reduce the contact area and facilitate the discharge of molten waste from the cutting process.

[0004] However, the waste generated during the cutting process adheres to the grating at the bottom of the sheet metal, affecting the grating's levelness and consequently the cutting accuracy. At this point, the grating needs to be cleaned and repaired to restore its supporting levelness. However, due to the limitations of the cutting machine's structure and the grating's size, replacing and cleaning the grating is quite troublesome, requiring the use of cranes, forklifts, and other equipment for lifting, which affects production efficiency. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a high-precision laser cutting device for intelligent furniture processing.

[0006] The technical solution of this utility model is:

[0007] A high-precision laser cutting device for intelligent furniture processing includes:

[0008] A cutting machine includes a frame, on the top surface of which a laser head is mounted via a three-axis moving mechanism. A worktable is provided between the frame and the laser head. The worktable includes a limiting mechanism and a grid. The limiting mechanism is used to fix the position of the grid, and the grid is used to ensure that the workpiece is horizontal. A changing assembly is provided on the front and rear sides of the frame for changing the grid of the worktable.

[0009] Preferably, the grille includes a support frame, in which a plurality of support frames are arranged laterally, and a plurality of support strips are arranged longitudinally between two adjacent support frames.

[0010] Preferably, the limiting mechanism includes a limiting guide rail, a roller is rotatably mounted on the top surface of the limiting guide rail, and the bottom surface of the support frame contacts the roller.

[0011] Preferably, the inner sides of both ends of the limiting guide rail are provided with support blocks, and the top surface of the support block abuts against the bottom surfaces of the front and rear sides of the support frame.

[0012] Preferably, the limiting mechanism further includes a fixing cylinder, which is fixedly installed on the outside of the limiting guide rail. A buckle plate is fixedly installed on the top of the fixing cylinder, and the buckle plate is snapped into the support frame and the support frame.

[0013] Preferably, the replacement assembly includes a rotating frame, which is rotatably mounted on the front and rear sides of the frame, and a lifting device is connected to the middle of the rotating frame.

[0014] Preferably, the top surface of the rotating frame is provided with a second guide rail, and a second roller is rotatably mounted on the top of the second guide rail, with the upper edge of the second roller flush with the bottom surface of the grid.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention utilizes a support frame to divide the support frame, which shortens the length of the support strips, reduces deformation, and ensures cutting accuracy. By using a limiting guide rail and rollers, the grid can be moved easily while restricting its direction of movement. A fixed cylinder drives the buckle plate to move, thus fixing the grid. A lifting device drives the rotating frame to rotate upward, making the second guide rail parallel to the grid, thereby moving the grid out from under the laser head. This facilitates the replacement of the support strips, reduces replacement time, and improves replacement efficiency. Attached Figure Description

[0027] Example 1:

[0028] Please see Figure 1-5 The present invention will describe the above technical solution in detail through the following embodiments:

[0029] A high-precision laser cutting device for intelligent furniture processing includes:

[0030] The cutting machine 1 includes a frame 11. A laser head 14 is mounted on the top surface of the frame 11 via a three-axis moving mechanism 12. A platform 2 is provided between the frame 11 and the laser head 14. The platform 2 includes a limiting mechanism and a grid. The limiting mechanism is used to fix the position of the grid, and the grid is used to ensure that the workpiece is horizontal. The front and rear sides of the frame 11 are provided with a changing assembly 3, which is used to change the grid of the platform 2.

[0031] The three-axis motion mechanism 12 employs a known three-axis servo motion platform, capable of driving the laser head 14 to move in the horizontal, vertical, and longitudinal directions. The laser head 14 generates laser light for cutting workpieces.

[0032] A discharge hopper 13 is fixedly installed on the bottom inner side of the frame 11 by bolts. The discharge hopper 13 is used to receive waste materials and some fallen parts generated during cutting.

[0033] The grille includes a support frame 21, and several support frames 22 are arranged horizontally inside the support frame 21. Several support bars 23 are arranged longitudinally between two adjacent support frames 22.

[0034] The support frame 21 can be made of square steel pipe by welding, and the support frame 22 can be made of steel plate by welding. The support frame 22 is welded to the support frame 21.

[0035] The support frame 22 is provided with several slots at intervals, and the support bar 23 is inserted into the slots on the top surface of the support frame 22.

[0036] The support bar 23 can be strip-shaped or serrated, and the top of the support bar 23 tapers towards the center in a blade-like shape.

[0037] The limiting mechanism includes a limiting guide rail 24, on the top surface of which a roller 25 is rotatably mounted, and the bottom surface of the support frame 21 contacts the roller 25.

[0038] The limiting guide rail 24 is fixedly installed on the top surface of the frame 11 by bolts or welding and is located on the left and right sides of the discharge hopper 13.

[0039] The outer side of the limiting guide rail 24 is higher than the roller 25 to prevent the support frame 21 from moving to the left or right.

[0040] Rollers 25 are used to support the forward and backward movement of the frame 21.

[0041] The inner sides of both ends of the limiting guide rail 24 are provided with support blocks 26, and the top surface of the support block 26 abuts against the bottom surfaces of the front and rear sides of the support frame 21.

[0042] The support block 26 is fixedly installed on the top surface of the frame 11 by bolts or welding and is located on the front and rear sides of the discharge hopper 13. It is used to provide support for the front and rear sides of the bottom of the support frame 21 and prevent the middle of the support frame 21 from bending downward.

[0043] The limiting mechanism also includes a fixed cylinder 27, which is fixedly installed on the outside of the limiting guide rail 24. A buckle plate 28 is fixedly installed on the top of the fixed cylinder 27 by bolts, and the buckle plate 28 is snapped into the support frame 22 and the support frame 21.

[0044] When the fixed cylinder 27 is working, it can drive the buckle plate 28 to move in the vertical direction.

[0045] When the buckle plate 28 moves downward, it can lock the support frame 22 and press down the support frame 21, thereby fixing the support frame 22 and the support frame 21.

[0046] When the buckle plate 28 moves upward, it can release the latching connection between the support frame 22 and the support frame 21, at which time the support frame 22 and the support frame 21 can move back and forth.

[0047] The replacement assembly 3 includes a rotating frame 31, which is rotatably mounted on the front and rear sides of the frame 11, and a lifting device 32 is connected to the middle of the rotating frame 31.

[0048] The lifting device 32 can be a known hydraulic cylinder, and the lifting device 32 is mounted between the rotating frame 31 and the frame 11. When the lifting device 32 is working, it can drive the rotating frame 31 to rotate.

[0049] When the rotating frame 31 rotates to a horizontal position, the top surface of the rotating frame 31 is flush with the top surface of the frame 11.

[0050] The top surface of the rotating frame 31 is fixedly mounted with a second guide rail 33 by bolts. A second roller 34 is rotatably mounted on the top of the second guide rail 33. The upper edge of the second roller 34 is flush with the bottom surface of the grid.

[0051] The second guide rail 33 is used to limit the direction of movement of the grille, and the second roller 34 is used for the horizontal movement of the grille.

[0052] Working principle:

[0053] When it is necessary to inspect the support bar 23, first determine the location of the support bar 23 that needs to be replaced or maintained.

[0054] Depending on the position of the support bar 23, select the replacement assembly 3 on the front or rear side of the utility rack 11.

[0055] The lifting device 32 is controlled to operate, driving the rotating frame 31 to rotate upward to a horizontal state.

[0056] The control cylinder 27 is activated, driving the buckle plate 28 to move upward, thus releasing the clamping connection between the support frame 21 and the support bracket 22.

[0057] A horizontal pulling force is applied to the support frame 21, and the support frame 21 is moved horizontally onto the second guide rail 33 using the roller 25 and the second roller 34.

[0058] Inspect the support bar 23, remove the old support bar 23, and insert the new support bar 23 into the support frame 22.

[0059] Then push the support frame 21 and support bracket 22 back to their original positions, control the fixing cylinder 27 to work, drive the buckle plate 28 to move downwards, and re-fix the support frame 21 and support bracket 22.
