Description

Technical Field

[0001] This invention relates to the field of sofa panel processing, and in particular to a high-efficiency continuous CNC drilling equipment for sofa panels. Background Technology

[0002] Sofa panels are the main base material for sofa frames, typically referring to engineered wood products such as plywood, particleboard, or medium-density fiberboard (MDF) that have undergone veneer, adhesive pressing, edge trimming, and edge treatment. In modern sofa manufacturing, to achieve complex curved shapes and a comfortable seating experience, sofa panels often require holes of various sizes and angles for subsequent installation of connectors, spring attachments, or fixing of decorative components. With the rapid development of the custom furniture market, the demand for personalized sofa products is increasingly prominent, and the hole layouts in different sofa styles vary significantly. This places higher demands on the flexibility, precision, and efficiency of panel drilling.

[0003] To address the need for efficient drilling of sofa panels, the industry has developed various continuous CNC drilling machines. These machines typically employ multi-station drilling technology, using multiple mounting bases on the frame. Each base can independently mount a drill bit and be equipped with a power unit, enabling simultaneous drilling of batches of panels and significantly improving production efficiency. Some advanced machines also incorporate CNC slide rail systems. For example, patent application number 202110089784.X discloses a continuous drilling device for furniture wood, which uses a grid-like adjustment structure formed by mutually perpendicular first and second slide rails. A control device drives the mounting bases to move on the slide rails, allowing adjustment of the base position according to different combinations of hole positions on the panel. This addresses, to some extent, the problems of fixed workstations and poor adaptability in traditional multi-station drilling machines.

[0004] Existing technologies generally suffer from limited adjustment range of drilling devices, the inability to achieve independent adjustment of arbitrary hole positions and inclined drilling, making it difficult to fully meet the diverse and personalized high-efficiency continuous drilling needs of sofa panels. Taking the patent with application number 202110089784.X as an example, its first slide rail is integrally slidably mounted on the second slide rail, causing multiple drilling devices mounted on the first slide rail to slide and adjust as a whole along the second slide rail, failing to achieve truly independent adjustment between the individual drilling devices. When dealing with sofa panels with complex and varied hole layouts, the adjustment flexibility remains insufficient. In addition, the drill bit of this device can only perform vertical drilling operations, while sofa manufacturing often requires the processing of inclined holes in areas such as armrests and legs to meet the needs of specific structural connections or styling designs. Summary of the Invention

[0005] The purpose of this invention is to provide a high-efficiency continuous CNC drilling device for sofa panels, aiming to solve the problem of fixed distances and coordination between various stations on a multi-stage drilling machine in existing continuous CNC drilling devices for sofa panels. While a "first slide rail and a second slide rail" are used to allow the drilling device to "adjust the base position according to the combination of different hole positions on the panel," the first slide rail is integrally slidably mounted on the second slide rail. The drilling device on the first slide rail can only slide and adjust as a whole on the second slide rail, making it impossible to truly achieve independent adjustment between multiple drilling devices. Furthermore, it lacks the capability to perform inclined drilling. In short, the existing technology suffers from a limited adjustment range for the drilling device.

[0006] Specifically: High-efficiency continuous CNC drilling equipment for sofa panels, including:

[0007] A sofa panel conveying assembly is used to continuously and intermittently convey sofa panels forward and perform subsequent processing operations.

[0008] A continuous CNC drilling assembly is assembled on the side of the sofa panel conveying assembly. The continuous CNC drilling assembly is used to continuously drill holes in the sofa panels conveyed by the sofa panel conveying assembly.

[0009] A powertrain, which is mounted on a continuous CNC drilling assembly, is used to drive the continuous CNC drilling assembly to rotate intermittently.

[0010] The continuous CNC drilling assembly includes multiple CNC drilling legs, each CNC drilling leg comprising a support plate and multiple unit CNC drilling heads arrayed on the support plate; each unit CNC drilling head includes:

[0011] A primary adjustment frame, which is used to independently adjust the drill bit in both the X-axis and Y-axis directions;

[0012] A secondary adjustment frame, which is mounted on a primary adjustment frame, is used to rotate and adjust the drilling angle of the drill bit;

[0013] When the sofa panels are transported to the continuous CNC drilling assembly station, the continuous CNC drilling assembly uses multiple CNC drilling legs to sequentially act on the sofa panels to be drilled. As the CNC drilling legs, via the support plate, apply multiple unit CNC drilling heads to the sofa panels for drilling operations, each unit CNC drilling head independently uses a primary adjustment frame for combined adjustment in the X and Y axes; and a secondary adjustment frame to rotate and adjust the drilling angle of the drill head. This allows for independent adjustment of the distribution distance between multiple unit CNC drilling heads and their distribution pattern on the support plate. The wide drill head adjustment range facilitates independent adjustment of any hole position and inclined drilling, fully adapting to the diverse and personalized high-efficiency continuous drilling needs of sofa panels.

[0014] The technical solution of this application will be further described below:

[0015] In one embodiment, the primary adjustment frame includes:

[0016] An assembly plate, which is bolted to a support plate;

[0017] The connecting column is integrally assembled on the bottom of the assembly plate;

[0018] The X-axis electric telescopic rod is mounted on the side wall of the connecting column; the connecting column and the X-axis electric telescopic rod are vertically distributed, and the X-axis electric telescopic rod is used to independently adjust the position of the drill bit in the X-axis direction;

[0019] The Y-axis electric telescopic rod is mounted on the X-axis electric telescopic rod; the X-axis electric telescopic rod and the Y-axis electric telescopic rod are perpendicularly distributed; the Y-axis electric telescopic rod is used to independently adjust the position of the drill bit in the Y-axis direction.

[0020] In one embodiment, the secondary adjustment frame includes:

[0021] A rotating frame, which is mounted on a primary adjustment frame; the rotating frame is used to rotate and adjust the drilling angle of the drill bit;

[0022] A drill bit mounting bracket is mounted on a rotating frame and is used for mounting drill bits.

[0023] Furthermore, the rotating frame includes:

[0024] A connecting block, which is fixed on the primary adjustment frame;

[0025] An upright plate, which is fixed to the connecting block;

[0026] The second servo motor is fixed at the end of the upright plate away from the connecting block.

[0027] Furthermore, the rotating frame also includes:

[0028] A support ring, which is fixed to the side wall of the upright plate;

[0029] A rotating disk is rotatably mounted on a support ring via a sealed bearing ring; the rotating disk is fixed on a drill bit mounting bracket.

[0030] A rotating shaft, one end of which is fixed on a rotating disk, and the other end of which is rotatably mounted on the output shaft of a second servo motor via a coupling.

[0031] Furthermore, the drill bit mounting bracket includes:

[0032] A drive shaft is fixed on a rotating disk and integrally fixed with the rotating disk;

[0033] Mounting frame, the mounting frame being fixed at the end of the drive shaft away from the rotating disk;

[0034] An electric actuator is inserted and fixed in the mounting frame.

[0035] Furthermore, the drill bit mounting bracket also includes:

[0036] A positioning plate, which is fixed to an electric push rod;

[0037] The mounting holes are formed on the positioning plate and are used for mounting drill bits.

[0038] In one embodiment, the CNC drilling support leg further includes:

[0039] A load-bearing column, one end of which is fixed to the side wall of the positioning turntable, and the positioning turntable is connected to the power assembly via a power transmission.

[0040] A connecting plate is fixed to the other end of the load-bearing column and to the support plate. The connecting plate is used to assemble the load-bearing column onto the support plate.

[0041] In one embodiment, the sofa panel conveying assembly includes:

[0042] A conveyor belt for continuously and intermittently conveying sofa panels forward;

[0043] A first support platform is mounted on the bottom of the conveyor belt;

[0044] The second support platform is assembled at the bottom of the conveyor belt;

[0045] Mounting plate, which is mounted on a first support platform, is used for powertrain mounting.

[0046] In one embodiment, the powertrain includes:

[0047] The first servo motor is used to drive the continuous CNC drilling assembly to rotate intermittently.

[0048] A support frame is mounted on the sofa panel conveyor assembly; the support frame is used for mounting the first servo motor.

[0049] In summary, a high-efficiency continuous CNC drilling equipment for sofa panels includes a sofa panel conveying assembly, a power assembly, and a continuous CNC drilling assembly. Sofa panels to be drilled are sequentially placed on the sofa panel conveying assembly, which employs a continuous-intermittent conveying method to precisely and stably transport the panels to each processing station. When a sofa panel is transported to the working station of the continuous CNC drilling assembly, the equipment enters the drilling preparation state. At this time, the power assembly driving the continuous CNC drilling assembly to rotate starts, and its transmission rhythm perfectly matches the intermittent pauses of the sofa panel conveying assembly. Specifically, during the intervals between pauses in the conveying assembly, the power assembly drives the continuous CNC drilling assembly to descend, performing drilling operations on the static panels, thus achieving a combined "dynamic-static" assembly line-style high-efficiency processing.

[0050] During drilling operations, the continuous CNC drilling assembly exhibits high flexibility and precision. It uses multiple CNC drilling legs as a support structure to transmit force to the support plate, thereby driving multiple unit CNC drilling heads to simultaneously act on the plate surface. Each unit CNC drilling head has completely independent X / Y axis plane coordinate adjustment capabilities: via the X-axis electric telescopic rod in the primary adjustment frame, the drill bit can move independently in the X-axis direction; via the Y-axis electric telescopic rod, the drill bit can move independently in the Y-axis direction. This allows multiple drill bits to adjust their relative distance and distribution pattern in real time and independently within the support plate range, based on preset hole position data, completely breaking the limitation of traditional drilling machines that can only move as a whole.

[0051] After the second servo motor built into the secondary adjustment frame is started, it precisely transmits the rotational power to the rotary table, driving the entire drill bit mounting frame to rotate at an angle, thereby realizing stepless adjustment of the drilling angle; after the angle is adjusted to the correct position, the electric push rod is started, and through the cooperation of the positioning plate and the mounting hole, it drives the drill bit to feed along the set direction to complete high-precision drilling.

[0052] Compared with the prior art, the present invention has the following advantages:

[0053] 1. When the sofa panel is transported to the continuous CNC drilling assembly station, the continuous CNC drilling assembly uses multiple CNC drilling legs to sequentially act on the sofa panel to be drilled. While the CNC drilling legs, via the support plate, apply multiple unit CNC drilling heads to the sofa panel for drilling operations, each unit CNC drilling head independently uses a primary adjustment frame for combined adjustment in the X and Y axes; and a secondary adjustment frame to rotate and adjust the drilling angle of the drill head. This allows for independent adjustment of the distribution distance between multiple unit CNC drilling heads and their distribution pattern on the support plate. The wide drill head adjustment range facilitates independent adjustment of any hole position and inclined drilling, fully adapting to the diverse and personalized high-efficiency continuous drilling needs of sofa panels.

[0054] 2. The primary adjustment frame enables independent displacement in the X and Y axes, while the secondary adjustment frame enables independent angular rotation. When combined, each CNC drilling head is not only an independent point but also a processing unit with an independent posture. This transforms the entire continuous CNC drilling assembly from a simple multi-axis drilling system into a programmable, flexible tool cluster. It can drill any array of holes on a plane and simultaneously process composite hole systems, including straight holes, angled holes, and holes of different depths and angles, on the same sheet metal. This three-dimensional processing capability allows sofa panels to complete the processing of all complex holes in a single clamping and pause, avoiding errors caused by tool changes or secondary positioning, resulting in a qualitative leap in processing accuracy.

[0055] 3. Traditional independent drill bit units are often limited by the size of the motor and the transmission structure, making it impossible to arrange them too densely. In this application, a support plate is used as a shared platform to vertically integrate the complex primary adjustment frame, secondary adjustment frame, and electric push rod at the rear of the drill bit mounting frame. This highly integrated three-dimensional layout allows multiple drill bits to be arranged extremely closely on the horizontal projection plane, and even achieves overlap of the drill bit working areas (by staggering the angles). This not only meets the processing requirements of extremely small hole spacing on sofa panels, but also unexpectedly solves the interference problem under high-density arrangement. When two adjacent drill bits need to drill angled holes close together, they can tilt outwards through the rotary table to cleverly avoid each other's rear end mechanisms, realizing complex multi-angle operations in extremely narrow spaces, which is completely unattainable by traditional fixed-spacing or single-axis mobile equipment.

Detailed Implementation

[0068] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. The specific implementation of the invention will be described in detail below with reference to specific embodiments.

[0069] In embodiments of the present invention, such as Figure 1 , Figures 3-7As shown: High-efficiency continuous CNC drilling equipment for sofa panels, including:

[0070] Sofa board conveying assembly 100 is used for continuously and intermittently conveying sofa boards forward and performing subsequent processing operations.

[0071] A continuous CNC drilling assembly 300 is assembled on the side of the sofa board conveying assembly 100. The continuous CNC drilling assembly 300 is used to continuously drill holes in the sofa board conveying assembly 100.

[0072] A powertrain 200 is mounted on a continuous CNC drilling assembly 300 and is used to drive the continuous CNC drilling assembly 300 to rotate intermittently.

[0073] Therefore, the sofa panels to be drilled are sequentially placed into the sofa panel conveyor assembly 100. The sofa panel conveyor assembly 100 continuously and intermittently conveys the sofa panels forward. When the sofa panels are transported to the station of the continuous CNC drilling assembly 300, the power assembly 200 that drives the continuous CNC drilling assembly 300 to rotate is matched with the continuous and intermittent transmission mode of the sofa panel conveyor assembly 100, so that the continuous CNC drilling assembly 300 can perform continuous CNC drilling on the sofa panels conveyed by the sofa panel conveyor assembly 100.

[0074] The continuous CNC drilling assembly 300 includes multiple CNC drilling legs 320, each CNC drilling leg 320 including a support plate 350 and multiple unit CNC drilling heads 360 arrayed on the support plate 350; each unit CNC drilling head 360 includes:

[0075] A primary adjustment frame 361 is used to independently adjust the drill bit in the X-axis and Y-axis directions.

[0076] A secondary adjustment frame 362 is mounted on a primary adjustment frame 361, and the secondary adjustment frame 362 is used to rotate and adjust the drilling angle of the drill bit;

[0077] Therefore, when the sofa panel is transported to the continuous CNC drilling assembly 300 station, the continuous CNC drilling assembly 300 uses multiple CNC drilling legs 320 to sequentially act on the sofa panel to be drilled. When the CNC drilling legs 320 use the support plate 350 to act on the sofa panel with multiple unit CNC drilling heads 360 for drilling operations, each unit CNC drilling head 360 independently uses a primary adjustment frame 361 to adjust the drill bit in the X-axis and Y-axis directions; and uses a secondary adjustment frame 362 to rotate and adjust the drilling angle of the drill bit. This allows for independent adjustment of the distribution distance between multiple unit CNC drilling heads 360 and the distribution pattern of multiple unit CNC drilling heads 360 on the support plate 350. The drill bit adjustment range is wide, which is conducive to realizing independent adjustment of any hole position and inclined drilling processing, and fully adapts to the diverse and personalized high-efficiency continuous drilling needs of sofa panels.

[0078] In embodiments of the present invention, such as Figure 5 and Figure 6 As shown: The primary adjustment frame 361 includes:

[0079] Assembly plate 3611 is bolted to support plate 350;

[0080] Connecting post 3612, which is integrally assembled on the bottom of mounting plate 3611;

[0081] X-axis electric telescopic rod 3613 is mounted on the side wall of connecting column 3612; connecting column 3612 and X-axis electric telescopic rod 3613 are vertically distributed, and X-axis electric telescopic rod 3613 is used to independently adjust the position of drill bit in the X-axis direction;

[0082] Y-axis electric telescopic rod 3614 is mounted on X-axis electric telescopic rod 3613; X-axis electric telescopic rod 3613 and Y-axis electric telescopic rod 3614 are perpendicularly distributed; Y-axis electric telescopic rod 3614 is used to independently adjust the position of the drill bit in the Y-axis direction.

[0083] Therefore, when the CNC drilling support leg 320 uses the support plate 350 to apply multiple unit CNC drilling heads 360 to the sofa board for drilling operations, each unit CNC drilling head 360 independently uses the primary adjustment frame 361 to independently adjust the position of the Y-axis electric telescopic rod 3614 and the drill bit in the X-axis direction via the X-axis electric telescopic rod 3613, and independently adjusts the position of the drill bit in the Y-axis direction via the Y-axis electric telescopic rod 3614, thus completing the combined adjustment of the drill bit in the X-axis and Y-axis directions; and uses the secondary adjustment frame 362 to rotate and adjust the drilling angle of the drill bit; realizing independent adjustment of the distribution distance between multiple unit CNC drilling heads 360 and the distribution pattern of multiple unit CNC drilling heads 360 on the support plate 350; the drill bit adjustment range is wide, which is conducive to realizing independent adjustment of any hole position and processing of inclined drilling, fully adapting to the diverse and personalized high-efficiency continuous drilling needs of sofa boards.

[0084] In embodiments of the present invention, such as Figure 5 , Figure 7 and Figure 8 As shown: The secondary adjustment frame 362 includes:

[0085] The rotating frame 363 is mounted on the primary adjustment frame 361 (specifically, the rotating frame 363 is mounted on the Y-axis electric telescopic rod 3614 of the primary adjustment frame 361); the rotating frame 363 is used to rotate and adjust the drilling angle of the drill bit.

[0086] A drill bit mounting bracket 364 is assembled on a rotating frame 363 and is used for mounting drill bits.

[0087] It should be added that: drill bits are existing technology and can be purchased directly on the market or assembled by purchasing parts, etc. Whether they are publicly available or not does not affect the protection of the primary adjustment frame 361 and the secondary adjustment frame 362, so they will not be discussed in detail here.

[0088] Furthermore, such as Figure 7 and Figure 8 As shown: The rotating frame 363 includes:

[0089] Connecting block 3631, which is fixed on the first-stage adjustment frame 361 (specifically, the connecting block 3631 is assembled on the Y-axis electric telescopic rod 3614 of the first-stage adjustment frame 361).

[0090] An upright plate 3632 is fixed on a connecting block 3631;

[0091] The second servo motor 3633 is fixed to the end of the upright plate 3632 away from the connecting block 3631.

[0092] Furthermore, such as Figure 7 As shown: The rotating frame 363 further includes:

[0093] Support ring 3634, the support ring 3634 is fixed to the side wall of the upright plate 3632;

[0094] Rotary disk 3635 is rotatably mounted on support ring 3634 via a sealed bearing ring; rotary disk 3635 is fixed on drill bit mounting bracket 364;

[0095] The rotating shaft has one end fixed on the rotating disk 3635 and the other end rotatably mounted on the output shaft of the second servo motor 3633 via a coupling.

[0096] Therefore, when the CNC drilling support leg 320 uses the support plate 350 to apply multiple unit CNC drilling heads 360 to the sofa board for drilling operations, each unit CNC drilling head 360 independently uses the secondary adjustment frame 362. The secondary adjustment frame 362 starts the second servo motor 3633, and the second servo motor 3633 provides rotational power to the rotary disk 3635. The rotary disk 3635 drives the drill bit to rotate through the drill bit mounting frame 364, thereby completing the rotation adjustment of the drilling angle of the drill bit.

[0097] It should be noted that the second servo motor 3633 and its power supply wiring method are existing technologies. Their detailed structure can be found in existing literature and journals, and they can also be purchased directly on the market, or components can be purchased on the market to assemble them, etc. They are not what this invention is intended to protect, and will not be described in detail here, nor are they shown in the accompanying drawings.

[0098] Furthermore, such as Figure 7 and Figure 8 As shown: The drill bit mounting bracket 364 includes:

[0099] The drive shaft 3641 is fixed on the rotating disk 3635 and is integrally fixed with the rotating disk 3635;

[0100] Mounting frame 3643, which is fixed at the end of the drive shaft 3641 away from the rotating disk 3635;

[0101] An electric push rod 3642 is inserted and fixed in the mounting frame 3643.

[0102] Furthermore, such as Figure 7 and Figure 8 As shown: The drill bit mounting bracket 364 also includes:

[0103] Positioning plate 3645, which is fixed to electric push rod 3642;

[0104] Mounting hole 3644 is formed on positioning plate 3645 and is used for mounting drill bit.

[0105] In summary, existing technologies generally suffer from limited adjustment range of drilling devices, inability to achieve independent adjustment of arbitrary hole positions and inclined drilling, making it difficult to fully meet the diverse and personalized high-efficiency continuous drilling needs of sofa panels; this application can achieve the following:

[0106] Sofa panels to be drilled are sequentially placed into the sofa panel conveyor assembly 100. The sofa panel conveyor assembly 100 continuously and intermittently conveys the sofa panels forward. When the sofa panels are transported to the station of the continuous CNC drilling assembly 300, the power assembly 200 that drives the continuous CNC drilling assembly 300 to rotate is matched with the continuous and intermittent transmission mode of the sofa panel conveyor assembly 100, so that the continuous CNC drilling assembly 300 can process the sofa panels conveyed from the sofa panel conveyor assembly 100. The sheet material undergoes continuous CNC drilling. When the sofa sheet material is transported to the continuous CNC drilling assembly 300 station, the assembly uses multiple CNC drilling legs 320 to sequentially act on the sofa sheet material to be drilled. While the CNC drilling legs 320, via the support plate 350, apply multiple unit CNC drilling heads 360 to the sofa sheet material for drilling, each unit CNC drilling head 360 independently uses a primary adjustment frame 361 connected to an X-axis electric telescopic rod 3613. The position of the Y-axis electric telescopic rod 3614 and the drill bit can be independently adjusted in the X-axis direction. The position of the drill bit can be independently adjusted in the Y-axis direction via the Y-axis electric telescopic rod 3614, thus completing the combined adjustment of the drill bit in the X-axis and Y-axis directions. The second servo motor 3633 is started using the secondary adjustment frame 362. The second servo motor 3633 provides rotational power to the rotary disk 3635. The rotary disk 3635 drives the drill bit to rotate through the drill bit mounting frame 364, thus completing the rotation adjustment of the drilling angle of the drill bit. After that, the electric push rod 3642 is started. The electric push rod 3642 drives the drill bit to drill through the positioning plate 3645 and the mounting hole 3644. It realizes the independent adjustment of the distribution distance between multiple unit CNC drilling heads 360 and the distribution pattern of multiple unit CNC drilling heads 360 on the support plate 350. The drill bit adjustment range is wide, which is conducive to realizing the independent adjustment of any hole position and the processing of inclined drilling, fully adapting to the diversified and personalized high-efficiency continuous drilling needs of sofa panels.

[0107] In embodiments of the present invention, such as Figure 3 and Figure 4 As shown: The CNC drilling support leg 320 further includes:

[0108] A load-bearing column 330, one end of which is fixed to the side wall of a positioning turntable 310, which is powered and connected to a power assembly 200.

[0109] A connecting plate 340 is fixed to the other end of the load-bearing column 330 and fixed to the support plate 350. The connecting plate 340 is used to assemble the load-bearing column 330 onto the support plate 350.

[0110] In embodiments of the present invention, such as Figure 1 and Figure 2 As shown: The sofa board conveying assembly 100 includes:

[0111] Conveyor belt 110, the conveyor belt 110 being used for continuously and intermittently forward conveying of sofa panels;

[0112] The first support platform 120 is mounted on the bottom of the conveyor belt 110;

[0113] The second support platform 130 is mounted on the bottom of the conveyor belt 110;

[0114] Mounting plate 140 is mounted on the first support platform 120 and is used for mounting the powertrain 200.

[0115] In embodiments of the present invention, such as Figure 1 and Figure 2 As shown: The powertrain 200 includes:

[0116] The first servo motor 220 is used to drive the continuous CNC drilling assembly 300 to rotate intermittently.

[0117] Support frame 210 is mounted on sofa board conveying assembly 100; support frame 210 is used for mounting first servo motor 220.

[0118] In summary, a high-efficiency continuous CNC drilling equipment for sofa panels includes a sofa panel conveying assembly 100, a power assembly 200, and a continuous CNC drilling assembly 300. Sofa panels to be drilled are sequentially placed on the sofa panel conveying assembly 100, which employs a continuous-intermittent conveying method to precisely and stably transport the panels to various processing stations. When a sofa panel is transported to the working station of the continuous CNC drilling assembly 300, the equipment enters the drilling preparation state. At this time, the power assembly 200, which drives the continuous CNC drilling assembly 300 to rotate, starts, and its transmission rhythm perfectly matches the intermittent pauses of the sofa panel conveying assembly 100. Specifically, during the pauses of the conveying assembly 100, the power assembly 200 drives the continuous CNC drilling assembly 300 to descend, performing drilling operations on the static panels, thus achieving a combined "dynamic-static" assembly line-style high-efficiency processing.

[0119] During drilling operations, the continuous CNC drilling assembly 300 exhibits high flexibility and precision. It uses multiple CNC drilling legs 320 as a support structure to transmit force to the support plate 350, thereby driving multiple unit CNC drilling heads 360 to simultaneously act on the plate surface. Each unit CNC drilling head 360 has completely independent X / Y axis plane coordinate adjustment capabilities: via the X-axis electric telescopic rod 3613 in the primary adjustment frame 361, the drill bit can move independently in the X-axis direction; via the Y-axis electric telescopic rod 3614, the drill bit can move independently in the Y-axis direction. This allows multiple drill bits to adjust their relative distance and distribution pattern in real time and independently within the support plate 350 according to preset hole position data, completely breaking the limitation of traditional drilling machines that can only move as a whole.

[0120] After the second servo motor 3633 built into the secondary adjustment frame 362 is started, it accurately transmits the rotational power to the rotary disk 3635, driving the entire drill bit mounting frame 364 to rotate at an angle, thereby realizing stepless adjustment of the drilling angle; after the angle is adjusted to the correct position, the electric push rod 3642 is started, and through the cooperation of the positioning plate 3645 and the mounting hole 3644, it drives the drill bit to feed along the set direction to complete high-precision drilling.

[0121] The primary adjustment frame 361 enables independent displacement in the X and Y axes, while the secondary adjustment frame 362 enables independent angular rotation. When combined, each unit CNC drilling head 360 is not only an independent point but also a processing unit with an independent posture. This results in the entire continuous CNC drilling assembly 300 no longer being a simple multi-axis drilling machine but evolving into a programmable flexible tool cluster. It can not only drill any array of holes on a plane but also simultaneously process composite hole systems, including straight holes, oblique holes, and holes of different depths and angles, on the same sheet metal. This three-dimensional processing capability allows sofa panels to complete the processing of all complex holes in a single clamping and one pause, avoiding errors caused by tool changes or secondary positioning, resulting in a qualitative leap in processing accuracy.

[0122] Traditional independent drill bit units are often limited by motor size and transmission structure, making it impossible to arrange them too densely. In this application, a support plate 350 is used as a common platform to vertically integrate the complex primary adjustment frame 361, secondary adjustment frame 362, and electric push rod 3642 behind the drill bit mounting frame 364. This highly integrated three-dimensional layout allows multiple drill bits to be arranged extremely closely on the horizontal projection plane, and even achieves overlap of the drill bit working areas (by staggering the angles). This not only meets the processing requirements of extremely small hole spacing on sofa panels, but also unexpectedly solves the interference problem under high-density arrangement. When two adjacent drill bits need to drill angled holes close together, they can tilt outwards through the rotary disk 3635 to cleverly avoid each other's rear end mechanisms, realizing complex multi-angle operations in extremely narrow spaces, which is completely unattainable by traditional fixed-spacing or single-axis mobile equipment.
