[0002] In furniture production, CNC milling machines are used to process grooves in furniture parts, allowing the parts to be assembled using mortise and tenon joints. This is one method of furniture manufacturing.

[0003] Chinese patent document CN220074963U discloses an environmentally friendly CNC milling machine for furniture production. With the linkage of sprockets and transmission chains, the milling machine can drive multiple rotating rods to rotate synchronously using a drive motor. When all rotating rods rotate in the direction of the stop block, the wood can be clamped and fixed by the clamping claws on the outer surface of the rotating rods and the stop block.

[0004] However, in the above solution, the distance between the stop block and the clamping claw is small, while the furniture parts have various structural shapes, such as boards, square columns and round columns. With the cooperation of the stop block and the clamping claw, only columnar structures such as square columns and round columns can be placed, which makes the furniture processing relatively inconvenient.

[0037] Example 1

[0038] like Figure 1-4 As shown, the present invention proposes a CNC milling machine, which includes a platform 1 with a cavity in the middle, an adjustment component, a limiting component, and a collecting component;

[0039] The main body of the slotting equipment (not shown in the prior art drawings) is slidably mounted on the back of the platform 1;

[0040] The adjustment assembly is installed inside the cavity of the stage 1 and one end extends to the outside of the stage 1. The two ends of the adjustment assembly and the inner side of the stage 1 are respectively provided with support assemblies for supporting the workpiece in use. The two support assemblies are arranged relative to each other on the adjustment assembly according to the center of the stage 1.

[0041] The limiting component is installed at the top of the support component and its bottom end extends into the inner bottom end of the support component;

[0042] The collection component is located at the bottom of the cavity of stage 1 and is connected to the adjustment component.

[0043] In this embodiment, the workpiece is supported by a support assembly and fixed on the support assembly by a limiting assembly. The workpiece is then slotted on the platform 1 by the main body of the slotting equipment. Simultaneously, the processed debris and waste fall into the collection assembly and are screened. At the same time, the two support assemblies are moved relative to or opposite to each other on the inner side of the platform 1 by an adjusting assembly, so that the distance between the two support assemblies can be adjusted, allowing workpieces of different sizes to be placed on the two support assemblies for slotting.

[0044] Example 2

[0045] like Figure 1 As shown, the present invention proposes a CNC milling machine. Compared with embodiment one, the difference in this embodiment is that the adjustment component includes a slide bar 3, a lead screw 5, and a motor 6.

[0046] The lead screw 5 is rotatably mounted on the inner side of the platform 1 and one end extends to the outer side of the platform 1.

[0047] The motor 6 is mounted on the outside of the platform 1 and is connected to the lead screw 5 for transmission.

[0048] The slide bar 3 is installed inside the platform 1 and located on the side of the lead screw 5 and is slidably connected to the support assembly.

[0049] In this embodiment, the motor 6 drives the lead screw 5 to rotate inside the platform 1, causing the lead screw 5 to move the two support components relative to or opposite to each other, thereby adjusting the distance between the two support components and allowing workpieces of different sizes to be placed on the two support components. At the same time, by providing a slide rod 3 that is slidably connected to the support inside the platform 1, the slide rod 3 supports the ends of the support components, improving the stability of the support components inside the platform 1.

[0050] Example 3

[0051] like Figure 2-3 As shown, the present invention proposes a CNC milling machine. Compared with the first embodiment, the difference in this embodiment is that the support assembly includes a mounting block 4, a support block 7, a mounting plate 8, and bolts 9.

[0052] Mounting block 4 is fitted on the outside of slide bar 3 and lead screw 5 and located on the inside of platform 1;

[0053] There are multiple support blocks 7. The support blocks 7 are installed on the top of the mounting block 4 and are arranged towards the middle of the platform 1. The projected shape of the support block 7 is L-shaped. The bottom inner side of the support block 7 is flush with the top of the platform 1. The support blocks 7 on the two mounting blocks 4 are arranged symmetrically and staggered.

[0054] Bolt 9 is bolted to the top of one end of support block 7, and the middle part of bolt 9 and near the top is cylindrical;

[0055] Mounting plate 8 is fitted onto the outside of the cylinder of bolt 9 and extends one end upwards toward the other end of support block 7.

[0056] In an optional embodiment, both ends of the lead screw 5 and the inner side of the platform 1 are provided with threads, and the two threads are arranged symmetrically with respect to the center of the platform 1. The middle of the mounting block 4 is provided with a first threaded hole 16. When the mounting block 4 and the lead screw 5 are installed together, the lead screw 5 is fitted into the first threaded hole 16. This is used to move the two mounting blocks 4 relative to each other or in opposite directions through the engagement of the first threaded hole 16 during use, so that the lead screw 5 can adjust the spacing between the two support blocks 7 through the mounting block 4, and place workpieces of different widths on the two support blocks 7.

[0057] In an optional embodiment, a pad 13 is bolted to the inner side of the support block 7 to separate the workpiece from the support block 7 during use and to prevent the support block 7 from pressing indentations on the surface of the workpiece.

[0058] In this embodiment, the workpiece is placed inside the support block 7 by the shape of the support block 7, and the limiting component is installed at one end of the mounting plate 8. At the same time, the mounting block 4 is installed on the lead screw 5 through the first threaded hole 16, so that the lead screw 5 drives the mounting block 4 to move inside the platform 1, and the two mounting blocks 4 simultaneously drive the support block 7 to move towards the middle of the platform 1, so that the two support blocks 7 exert pressure on the workpiece, fix the position of the workpiece, and press the workpiece downward by the limiting component, so that the placement of the workpiece is more stable.

[0059] Example 4

[0060] like Figure 4 As shown, the present invention proposes a CNC milling machine. Compared with embodiment one, the difference in this embodiment is that the limiting component includes an adjusting rod 10 and a pressure block 11.

[0061] The adjusting rod 10 is installed at one end of the mounting plate 8 and its bottom end extends toward the top of one end of the support block 7, and its bottom end is spherical;

[0062] The pressure block 11 is rotatably mounted on the bottom end of the adjusting rod 10.

[0063] In an optional embodiment, the top end of the adjusting rod 10 is provided with a connector 17 and the bottom end of the pressure block 11 is provided with a gasket 12.

[0064] In an optional embodiment, one end of the mounting plate 8 is provided with a second threaded hole 18, and the outer side of the adjusting rod 10 is provided with threads. When the adjusting rod 10 is installed in conjunction with the mounting plate 8, the adjusting rod 10 is accommodated in the second threaded hole 18.

[0065] In this embodiment, by cooperating with the adjusting rod 10 and the second threaded hole 18, after use, an external tool is connected to the connector 17 and the connector 17 is turned to adjust the position of the adjusting rod 10 inside the second threaded hole 18, and the adjusting rod 10 drives the pressure block 11 to move towards the workpiece, so that the adjusting rod 10 drives the pressure block 11 to press the workpiece and fix the workpiece on the support block 7. At the same time, the pressure block 11 and the workpiece are separated by the gasket 12 to prevent the pressure block 11 from directly contacting the workpiece and damaging the surface of the workpiece.

[0066] Example 5

[0067] like Figure 1 As shown, the present invention proposes a CNC milling machine. Compared with embodiment one, the difference in this embodiment is that the collection component includes a collection box 2, a lever 14, and a screen 15.

[0068] The collection box 2 is located at the bottom inner side of the platform 1 and has a cavity with an opening at the top in the middle.

[0069] The screen 15 is installed inside the collection box 2, and its edge is fitted and connected to the inner wall of the collection box 2.

[0070] The lever 14 is installed at the bottom end of the mounting block 4 and extends into the inside of the collection box 2 and is slidably connected to the screen 15. The lever 14 is made of a soft material, such as a rubber rod.

[0071] In this embodiment, the debris and scraps generated during the processing are collected by the collection box 2, and the scraps are supported and filtered inside the collection box 2 by the screen 15. At the same time, the lever 14 installed at the bottom of the mounting block 4 drives the lever 14 to move the scraps and debris at the top of the screen 15 during the movement of the mounting block 4, so that the screen 15 can separate the debris and scraps more thoroughly.

[0072] In this invention, the motor 6 drives the lead screw 5 to rotate inside the platform 1, causing the lead screw 5 to move the two mounting blocks 4 relative to or opposite to each other according to the workpiece width. This ensures that the distance between the two mounting blocks 4 matches the workpiece width. The workpiece is then placed inside the support block 7 via the pad 13. Simultaneously, the mounting blocks 4 continue to move, causing the symmetrically arranged support blocks 7 on the two mounting blocks 4 to press against the workpiece, thus limiting its position. Finally, by turning the connector 17, the position of the adjusting rod 10 inside the second threaded hole 18 is adjusted. The adjustment rod 10 drives the pressure block 11 to move towards the workpiece and is rotatably connected to the pressure block 11 through the adjustment rod 10. The adjustment rod 10 drives the pressure block 11 to press the workpiece and restrict its position. The grooving equipment body performs grooving work, while the processing debris and scrap fall onto the screen 15. The screen 15 supports the debris and sieves it into the collection box 2. The movement of the mounting block 4 drives the lever 14 to move on the screen 15. The lever 14 moves the debris and scrap at the top of the screen 15, so that the screen 15 can separate the debris and scrap more thoroughly.

[0073] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
