Description

Technical Field

[0001] The present invention relates to the technical field of wood board processing, and in particular to a drilling and milling mechanism based on a wood door processing technology and a control method thereof. Background Art

[0002] CNC six-sided drilling equipment is a highly efficient and high-precision automated process for wooden door processing, capable of drilling, slotting, and milling on all six surfaces of a wooden door. Existing CNC six-sided drilling equipment primarily consists of a machine frame, a multi-axis motion system, upper and lower drill kits, an automatic tool changer with a tool magazine, and a clamping and positioning system. When using CNC six-sided drilling equipment to create lock slots on wooden doors, the automatic tool changer switches between tools equipped with an angle head (also known as a side milling head) to create a slot on one side of the door. However, due to the large machining depth of lock slots, such as those exceeding 100mm, the angle head is prone to gear vibration and backlash, resulting in oversized slots and reduced machining accuracy. Furthermore, frequent use of the angle head can lead to internal gear transmission issues, causing it to overheat, shortening its service life. Summary of the Invention

[0003] The present invention aims to address at least one of the technical problems existing in the prior art. To this end, the present invention provides a drilling and milling mechanism and control method based on wooden door processing technology. This mechanism is capable of producing door lock holes, hinge slots, and door lock slots on wooden doors with high precision. Furthermore, the mechanism is compact and avoids the overheating and shortened lifespan of angle heads commonly found in the prior art due to frequent use.

[0004] The first embodiment of the present invention provides a drilling and milling mechanism based on a wooden door processing technology, which includes: An upper drill package assembly, wherein a support seat is provided on one side of the upper drill package assembly along the second direction, and the upper drill package assembly is provided on the support seat; A two-axis motion assembly, used for adjusting the position of the support base in the up-down direction and the first direction; an automatic tool changing assembly, which is disposed on the support base and can move up and down relative to the support base, the automatic tool changing assembly is located on one side of the upper drill package assembly along the first direction, and the automatic tool changing assembly includes a first tool extending in the up and down direction for processing a door lock hole on the wooden door; A horizontal milling groove assembly is provided on the support seat and can move up and down relative to the support seat. The horizontal milling groove assembly is located on the other side of the upper drilling package assembly along the first direction. The horizontal milling groove assembly includes a rotary driving member, a second tool for processing the hinge groove on the wooden door, and a third tool for processing the door lock groove on the wooden door. The rotary driving member has two driving shafts extending along the first direction. The second tool and the third tool both extend along the first direction and are respectively connected to the two driving shafts. The second tool is shorter than the third tool. The second tool is located on the side of the third tool close to the upper drilling package assembly along the first direction. The first direction, the second direction and the up and down directions are perpendicular to each other.

[0005] The drilling and milling processing mechanism based on the wooden door processing technology according to the embodiment of the first aspect of the present invention has at least the following beneficial effects: when it is necessary to manufacture a door lock hole on the upper surface of the wooden door, the position of the automatic tool changing assembly in the first direction and the up and down directions is adjusted by the operation of the two-axis motion assembly. Moreover, since the automatic tool changing assembly can move downward relative to the support seat, the height position of the first tool can be adjusted to avoid the operation of the first tool being obstructed by the upper drilling package assembly and the horizontal milling groove assembly, thereby enabling the first tool to process the door lock hole on the wooden door during high-speed rotation.

[0006] When it is necessary to manufacture a hinge groove on a side of a wooden door away from the door lock hole along the first direction, the position of the second tool of the horizontal milling assembly in the first direction and the up and down directions is adjusted by the operation of the two-axis motion assembly. Moreover, the horizontal milling assembly can move downward relative to the support seat, thereby adjusting the height position of the second tool to prevent the operation of the second tool from being obstructed by the upper drilling package assembly and the automatic tool changing assembly, thereby enabling the second tool to process the hinge groove of the wooden door during high-speed rotation.

[0007] When it is necessary to manufacture a door lock groove on a side of a wooden door close to the door lock hole along the first direction, the position of the third tool of the horizontal milling groove assembly in the first direction and the up and down directions is adjusted by the operation of the two-axis motion assembly. Moreover, the horizontal milling groove assembly can move downward relative to the support seat, so that the height position of the third tool can be adjusted to avoid the work of the third tool being obstructed by the upper drilling package assembly and the automatic tool changing assembly, so that the third tool can be able to process the door lock groove of the wooden door during high-speed rotation.

[0008] Since the hinge groove and door lock groove of the wooden door can be processed respectively by the second tool and the third tool of the horizontal milling assembly, there is no need for an automatic tool changing assembly to complete it through a tool with an angle head. Therefore, the hinge groove and door lock groove can be manufactured on the wooden door with high precision, avoiding the problem of gear vibration and clearance problems in the angle head in the prior art during power transmission, which leads to the groove position of the manufactured door lock groove being too large, thereby causing a decrease in processing accuracy. At the same time, it can also avoid the problems of the angle head being prone to overheating, shortening its service life and increasing the number of maintenance times during frequent use.

[0009] Moreover, the automatic tool changing assembly and the horizontal milling assembly are respectively arranged on both sides of the upper drill package assembly along the first direction. The length of the second tool is smaller than that of the third tool. The second tool is arranged between the first tool and the third tool, so that the second tool is closer to the upper drill package assembly relative to the third tool, thereby reducing the distance between the horizontal milling assembly and the upper drill package assembly along the first direction, making the structure of the drilling and milling processing mechanism more compact, and the processing positions of the first tool, the second tool and the third tool can be adjusted in sequence in the same direction along the first direction through the two-axis motion assembly, so as to process the door lock hole, hinge groove and door lock groove on the wooden door in sequence, thereby reducing the total processing stroke, thereby improving processing efficiency and saving energy consumption.

In the description of the present invention, unless otherwise specified, "several" means one or more, and "a plurality" means two or more.

[0025] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0026] Reference below Figures 1 to 10 The present invention describes a drilling and milling mechanism based on a wooden door processing technology and a control method thereof.

[0027] like Figures 1 to 9As shown, the drilling and milling mechanism based on the wood door processing technology according to the first embodiment of the present invention can be used as a component of a six-sided drilling machine and can be applied to the processing of wooden boards to produce slots and holes in the boards. The drilling and milling mechanism based on the wood door processing technology of this embodiment can accurately process door lock holes, hinge slots, and door lock slots on wooden doors (such as cabinet doors). Moreover, it has a compact structure and can effectively avoid the overheating and shortened lifespan of the angle head in the prior art due to frequent use.

[0028] The drilling and milling mechanism based on the wooden door processing technology has a first direction, a second direction and an up-down direction, wherein the first direction and the second direction are perpendicular to the up-down direction. In this embodiment, it is assumed that the first direction is the left-right direction and the second direction is the front-back direction.

[0029] The drilling and milling mechanism based on the wooden door processing technology includes an upper drilling package component 400, a two-axis motion component, an automatic tool changing component 300 and a horizontal milling groove component 200.

[0030] The function of the upper drill package assembly 400 is to process screw holes, connection holes, etc. on the upper surface and four side surfaces of the wooden door. The upper drill package assembly 400 is provided with a support seat 140 on one side along the second direction, and the upper drill package assembly 400 can be fixed to the support seat 140 by bolts. In this embodiment, the upper drill package assembly 400 is located in front of the support seat 140. It can be understood that the upper drill package assembly 400 is an existing structure, and this embodiment does not make structural improvements thereto. Therefore, those skilled in the art should understand its specific structure and working principle, which will not be described in detail here. The specific shape of the support seat 140 is not limited.

[0031] In addition, it is not ruled out that in other embodiments, the drilling and milling processing mechanism based on the wooden door processing technology also includes existing structures such as a lower drill package assembly, an air flotation platform and a clamping and positioning system, wherein the clamping and positioning system includes a clamping robot for clamping the wooden door, and the clamping robot can clamp the wooden door and drive the wooden door to move along the second direction on the air flotation platform.

[0032] The two-axis motion assembly is used to adjust the position of the support base 140 and the upper drill package assembly 400 thereon in the vertical direction and the first direction. It is understood that the two-axis motion assembly can be a two-axis linear module or a two-axis drive device such as a structural combination of the lifting mechanism 110 and the translation mechanism 120.

[0033] Specifically, the structure of the two-axis motion assembly includes a frame, a lifting mechanism 110, a translation seat 130 and a translation mechanism 120. The lifting mechanism 110 and the translation mechanism 120 are both fixed on the translation seat 130. The translation mechanism 120 includes a motor and a driving gear. The driving gear is fixedly connected to the output shaft of the motor. The frame is provided with a rack extending along a first direction. The driving gear is meshed with the rack. Moreover, a guide rail slider pair is provided between the translation seat 130 and the frame. When the motor is running, the driving gear rotates and can roll along the rack, so that the translation seat 130 can drive the lifting mechanism 110 to move back and forth along the first direction. The lifting mechanism 110 is a screw drive device, and a guide rail slider pair is also provided between the support seat 140 and the translation seat 130. The support seat 140 is also threadedly connected to the screw of the lifting mechanism 110. Therefore, when the lifting mechanism 110 is working, the support seat 140 can drive the upper drill package assembly 400 to rise and fall along the screw to adjust the height position of the upper drill package assembly 400.

[0034] The automatic tool changer assembly 300 can be fixed to the support base 140 via bolts, allowing the automatic tool changer assembly 300 to rise and fall with the support base 140 and move vertically relative to the support base 140. The automatic tool changer assembly 300 is located on one side of the upper drill assembly 400 along the first direction. The automatic tool changer assembly 300 includes a first cutting tool 320 that extends vertically to process the door lock hole on the wooden door.

[0035] Specifically, the automatic tool changing assembly 300 also includes a third drive member 331, a second lifting seat 332 and a drive motor 310. The third drive member 331 is fixedly mounted on the support seat 140, and the output end of the third drive member 331 is fixedly connected to the second lifting seat 332. When the third drive member 331 is working, the output end of the third drive member 331 can drive the second lifting seat 332 to move in the up and down directions. The drive motor 310 is fixedly mounted on the second lifting seat 332 and can move up and down with the second lifting seat 332. The output shaft of the drive motor 310 extends downward, and the output shaft of the drive motor 310 is detachably connected to the first tool 320 so that the first tool 320 can be replaced according to the design of the door lock hole.

[0036] It is understood that the third drive member 331 can be a linear drive device such as a pneumatic cylinder, an electric cylinder, a hydraulic cylinder, or a linear module. In this embodiment, the third drive member 331 is a telescopic cylinder, the second lifting seat 332 is located in front of the support seat 140, and a guide rail slider pair is provided between the second lifting seat 332 and the support seat 140. The movable rod of the third drive member 331 extends in the vertical direction and is fixedly connected to the second lifting seat 332. Therefore, when the first tool 320 of the automatic tool changing assembly 300 is needed, the third drive member 331 is operated to move the first tool 320 downward to create a door lock hole on the upper surface of the wooden door; when the first tool 320 is no longer needed, the third drive member 331 is operated to drive the first tool 320 upward to return to its initial height position, thereby completing the reset of the first tool 320. Since the automatic tool changing assembly 300 is usually equipped with a tool magazine, the first tool 320 can be removed from the output shaft of the driving motor 310 and a first tool 320 of appropriate size can be installed to create a door lock hole on the wooden door.

[0037] The horizontal milling assembly 200 is fixed to the support base 140 and is movable in the vertical direction relative to the support base 140. The horizontal milling assembly 200 is located on the other side of the upper drill assembly 400 along the first direction. Thus, the upper drill assembly 400 is located between the automatic tool change assembly 300 and the horizontal milling assembly 200. The horizontal milling assembly 200 includes a rotary drive 210, a second cutting tool 220, and a third cutting tool 230. The second cutting tool 220 is used to process the hinge groove on the wooden door, and the third cutting tool 230 is used to process the door lock groove on the wooden door.

[0038] The rotary drive member 210 has two drive shafts, both of which extend in a first direction and are capable of rotating simultaneously. In this embodiment, the rotary drive member 210 is a double-ended motor, with power being transmitted from both ends of the rotary drive member 210. The second cutter 220 and the third cutter 230 both extend in the first direction, and are fixedly connected to the two drive shafts, respectively. When the rotary drive member 210 is in operation, the two drive shafts of the rotary drive member 210 can respectively drive the second cutter 220 and the third cutter 230 to rotate simultaneously at high speed. The second cutter 220 is shorter than the third cutter 230. Furthermore, the second cutter 220 is located on the side of the third cutter 230 that is closer to the upper drill package assembly 400 along the first direction, so that the second cutter 220 is positioned between the third cutter 230 and the upper drill package assembly 400.

[0039] Specifically, the horizontal slot milling assembly 200 also includes a first drive member 241 and a first lift base 243. The first drive member 241 is fixedly mounted on the support base 140, and its output end is fixedly connected to the first lift base 243. When the first drive member 241 is in operation, the output end of the first drive member 241 can drive the first lift base 243 to move vertically. The rotary drive member 210 is connected to the bottom of the first lift base 243 and can follow the first lift base 243 in its up and down motion.

[0040] It is understood that the first drive member 241 can be a linear drive device such as a pneumatic cylinder, electric cylinder, hydraulic cylinder, or linear module. In this embodiment, the horizontal slot milling assembly 200 also includes a first mounting base 242, which is fixedly connected to the support base 140. The first drive member 241 is mounted on the first mounting base 242. The first lifting base 243 is located on the side of the first mounting base 242 away from the upper drill package assembly 400 in the first direction. A guide rail slider pair is provided between the first lifting base 243 and the first mounting base 242. The first drive member 241 is a telescopic cylinder, and the movable rod of the first drive member 241 extends in the vertical direction and is fixedly connected to the first lifting base 243.

[0041] Therefore, when the second cutter 220 or the third cutter 230 of the horizontal slot milling assembly 200 is needed, the first drive member 241 is operated to move the second cutter 220 and the third cutter 230 downward to create a hinge slot or a door lock slot on the side of the wooden door; when the second cutter 220 or the third cutter 230 is no longer needed, the first drive member 241 is operated to drive the second cutter 220 and the third cutter 230 upward to return to their initial height position, thereby completing the reset operation of the second cutter 220 and the third cutter 230. The first cutter 320, the second cutter 220, and the third cutter 230 can be cutters with spiral chip removal grooves, which have good and stable chip removal functions, avoiding the slot being too large due to the inability to remove wood chips, thereby ensuring high processing accuracy.

[0042] In this embodiment, the length of the second cutting tool 220 is set to 50 mm, and the length of the third cutting tool 230 is set to 120 mm. In the door lock groove processing process, the processing depth of the door lock groove is generally required to be 100 mm or more. In addition, the processing range of the door lock groove is large (i.e., the dimension along the second direction is large). Therefore, in this embodiment, the longer third cutting tool 230 is used to process the door lock groove on one side of the wooden door along the first direction.

[0043] If the automatic tool changer assembly 300 is used in conjunction with an angle head and a cutting tool to machine the door lock slot, the gear transmission structure within the angle head can achieve a 90° change in power transmission direction, allowing the power from the main shaft of the automatic tool changer assembly 300 to be transmitted to the cutting tool at right angles. However, due to gear vibration and backlash, the angle head is prone to vibration when machining side slots exceeding a certain depth, such as the door lock slot, such as 50 mm. This results in the machined door lock slot being too large and not meeting design requirements. However, this embodiment primarily utilizes the third cutting tool 230 of the horizontal slot milling assembly 200, rather than the automatic tool changer assembly 300, to complete the door lock slot. This improves the machining accuracy of the door lock slot to meet design requirements, effectively preventing the reduction in machining accuracy due to angle head vibration and backlash. Furthermore, it prevents the angle head from overheating and shortening its lifespan due to frequent use. This effectively addresses the existing problems of horizontal milling of door lock slots, including difficulty, low machining accuracy, and heating of the angle head, that result from the use of angle heads and cutting tools in the conventional art.

[0044] In the hinge groove machining process, the machining depth of the hinge groove is typically several millimeters. Therefore, in this embodiment, a shorter second tool 220 is used to machine the hinge groove on the other side of the wooden door along the first direction. Based on the provision of the horizontal milling groove assembly 200, the second tool 220 is positioned closer to the upper drill assembly 400, while the third tool 230 is positioned further away from the upper drill assembly 400. This results in a more compact structure, allowing the first lifting base 243 to meet the machining travel of the second tool 220 with a smaller dimension along the first direction. This effectively avoids the increase in the dimension of the first lifting base 243 along the first direction caused by the placement of the third tool 230 closer to the upper drill assembly 400, thereby saving manufacturing material for the first lifting base 243.

[0045] In the drilling and milling processing mechanism based on the wooden door processing technology provided by the embodiment of the first aspect of the present invention, when it is necessary to manufacture a door lock hole on the upper surface of the wooden door, the position of the automatic tool changing assembly 300 in the first direction and the up and down directions is adjusted by the operation of the two-axis motion assembly. Moreover, since the automatic tool changing assembly 300 can move downward relative to the support seat 140, the height position of the first tool 320 can be adjusted to avoid the work of the first tool 320 being obstructed by the upper drilling package assembly 400 and the horizontal milling groove assembly 200, thereby enabling the first tool 320 to perform door lock hole processing on the wooden door during high-speed rotation.

[0046] When it is necessary to manufacture a hinge groove on a side of the wooden door away from the door lock hole along the first direction, the position of the second tool 220 of the horizontal milling groove assembly 200 in the first direction and the up and down directions is adjusted by the operation of the two-axis motion assembly. Moreover, the horizontal milling groove assembly 200 can move downward relative to the support seat 140, so that the height position of the second tool 220 can be adjusted to prevent the operation of the second tool 220 from being obstructed by the upper drilling package assembly 400 and the automatic tool changing assembly 300, so that the second tool 220 can perform hinge groove processing on the wooden door during high-speed rotation.

[0047] When it is necessary to manufacture a door lock groove on a side of a wooden door close to the door lock hole along the first direction, the position of the third tool 230 of the horizontal milling groove assembly 200 in the first direction and the up and down directions is adjusted by the operation of the two-axis motion assembly. Moreover, the horizontal milling groove assembly 200 can move downward relative to the support seat 140, so that the height position of the third tool 230 can be adjusted to avoid the work of the third tool 230 being obstructed by the upper drilling package assembly 400 and the automatic tool changing assembly 300, so that the third tool 230 can be able to process the door lock groove of the wooden door during high-speed rotation.

[0048] Since the hinge groove and door lock groove of the wooden door can be processed respectively by the second tool 220 and the third tool 230 of the horizontal milling assembly 200, there is no need for the automatic tool changing assembly 300 to complete the process through the tool with an angle head. Therefore, the hinge groove and door lock groove can be manufactured on the wooden door with high precision, avoiding the problem of the angle head in the prior art causing the slot position of the manufactured door lock groove to be too large due to gear vibration and clearance problems during power transmission, thereby causing a decrease in processing accuracy. At the same time, it can also avoid the problems of the angle head being prone to overheating, shortening its service life and increasing the number of maintenance times during frequent use.

[0049] Moreover, the automatic tool changing assembly 300 and the horizontal milling assembly 200 are respectively arranged on both sides of the upper drill package assembly 400 along the first direction. The length of the second tool 220 is smaller than the length of the third tool 230. The second tool 220 is arranged between the first tool 320 and the third tool 230, so that the second tool 220 is closer to the upper drill package assembly 400 relative to the third tool 230, thereby reducing the distance between the horizontal milling assembly 200 and the upper drill package assembly 400 along the first direction, making the structure of the drilling and milling processing mechanism more compact, and the processing positions of the first tool 320, the second tool 220 and the third tool 230 can be adjusted in sequence in the same direction along the first direction through the two-axis motion assembly, so as to process the door lock hole, hinge groove and door lock groove on the wooden door in sequence, thereby reducing the total processing stroke, thereby improving processing efficiency and saving energy consumption.

[0050] When the drilling and milling processing mechanism based on the wooden door processing technology of this embodiment becomes a component of the six-sided drilling processing equipment, it can solve the defects of the six-sided drilling processing equipment in the wooden door processing technology, such as the problem that the automatic tool changing assembly 300 drives the tool through the angle head to manufacture a door lock groove with a large depth, and realizes the diversified processing technology of the six-sided drilling processing equipment, which can create a multifunctional drilling and milling processing center, solve the shortcomings of horizontal processing milling grooves, and improve the accuracy of horizontal processing milling grooves.

[0051] In some embodiments, as Figures 3 to 6 As shown, the structure of the horizontal slot milling assembly 200 also includes a second drive member 252 and a first pressure plate 251. The first pressure plate 251 is used to press down the wooden door when machining the door lock slot. The first pressure plate 251 is located above the third tool 230. Two first pressure plates 251 are provided, one on either side of the third tool 230 along the second direction. The second drive member 252 is fixedly mounted on the first lifting platform 243 and can move up and down with the first lifting platform 243. The output end of the second drive member 252 is fixedly connected to the two first pressure plates 251. When the second drive member 252 is in operation, the output end of the second drive member 252 can drive the first pressure plates 251 to move up and down. A first air outlet is provided on the lower surface of the first pressure plate 251. There are multiple first air outlets, and the multiple first air outlets can be arranged in a matrix. The first pressure plate 251 is provided with a first air cavity, which is connected to the multiple first air outlets, so that the gas in the first air cavity can flow out through the multiple first air outlets.

[0052] It is understood that the second drive member 252 can be a linear drive device such as a cylinder, an electric cylinder, a hydraulic cylinder, or a linear module. In this embodiment, the second drive member 252 is a telescopic cylinder. The movable rod of the second drive member 252 is connected to a connecting block 254. The middle portion of the lower surface of the connecting block 254 is recessed to form a U-shaped notch. The two first pressing plates 251 are fixedly connected to the lower surface of the connecting block 254 and are symmetrically arranged along the second direction about the U-shaped notch. The first pressing plate 251 can be in the shape of a rectangular block. The first pressing plate 251 is provided with a first gas inlet connected to the first air cavity. The first gas inlet can be connected to a gas supply device such as a gas tank via a pipeline. The first pressing plate 251 is configured to blow air onto the upper surface of the wooden door when the first pressing plate 251 is about to press down on the wooden door to blow away wood chips and dust.

[0053] During the door lock slot machining process, the wooden door is placed on an air flotation platform and held in place by a clamping manipulator. Driven by the clamping manipulator, the wooden door can be moved back and forth in a second direction on the air flotation platform. The air flotation platform applies air to the wooden door, providing frictionless, stable support. During the door lock slot machining process, the second driving member 252 drives the two first pressing plates 251 downward to apply pressure to the upper surface of the wooden door, preventing the wooden door from warping during the door lock slot machining process, which would reduce the machining accuracy of the door lock slot.

[0054] Before the first pressing plate 251 contacts and compresses the wooden door, the first pressing plate 251 can eject air downward to remove impurities such as sawdust and dust from the upper surface of the wooden door, thereby preventing the upper surface of the wooden door from being scratched by impurities such as dust and sawdust. During the continuous ejection of air, the first pressing plate 251 exerts a contactless downward pressure on the wooden door through the action of air pressure, thereby preventing the wooden door from being scratched when it moves in the second direction relative to the first pressing plate 251.

[0055] The U-shaped notch on the connecting block 254 prevents the first pressing plates 251 from pressing against the third cutter 230 and damaging it when the second driving member 252 drives the two first pressing plates 251 downward into position. Furthermore, once the lock hole has been manufactured, when the first pressing plate 251 is pressed against the upper surface of the wooden door, the U-shaped notch can be positioned vertically opposite the lock hole. At this point, the high-speed rotation of the third cutter 230 allows wood chips to be removed from the third cutter 230 and subsequently discharged through the lock hole and the U-shaped notch, thereby improving chip removal efficiency and ensuring high machining precision for the lock hole.

[0056] Further, such as Figures 4 to 6 As shown, the horizontal slot milling assembly 200 further includes an adjustment seat 253. The adjustment seat 253 is provided with a plurality of elongated holes 255 extending along a first direction. The first lifting seat 243 is provided with a connecting hole. The adjustment seat 253 is fixedly connected to the first lifting seat 243 via bolts passing through the elongated holes 255 and the connecting hole. The second driving member 252 is fixedly mounted on the adjustment seat 253.

[0057] In this embodiment, the adjustment seat 253 can be designed to have a triangular shape when viewed along the second direction. Two elongated holes 255 are provided, spaced apart along the second direction. The elongated holes 255 extend vertically, allowing bolts to pass through the elongated holes 255 from top to bottom and threadably connect with the connecting holes, thereby securing the adjustment seat 253 to the first lifting seat 243. To adjust the position of the first pressing plate 251 along the first direction based on the length of the third tool 230, the bolts are loosened, causing the adjustment seat 253 to move the second driving member 252 and the first pressing plate 251 an appropriate distance along the first direction. After the positions are adjusted, the bolts are tightened. This arrangement allows the position of the first pressing plate 251 to be adjusted arbitrarily based on the machining depth of the door lock slot, allowing the first pressing plate 251 to exert a compressive force on the wooden door during the manufacturing process of the door lock slot.

[0058] Furthermore, Figures 4 to 6 As shown, the horizontal slot milling assembly 200 further includes a second dust hood 262 and a third dust hood 263. The second dust hood 262 is fixedly mounted on the first lifting base 243 and positioned above the second tool 220. A second dust suction port is provided on the lower surface of the second dust hood 262, and a second vacuum port is provided on the second dust hood 262. The third dust hood 263 is fixedly mounted on the first lifting base 243 and positioned on a side of the second dust hood 262 away from the upper drill package assembly 400 along the first direction. The third dust hood 263 is positioned above the third tool 230, and a third dust suction port is provided on the lower surface of the third dust hood 263, and a third vacuum port is provided on the third dust hood 263.

[0059] It is understood that the second vacuum port and the third vacuum port can be connected to a vacuuming device via a pipe. When the vacuuming device is in operation, the interior of the second dust hood 262 and the interior of the third dust hood 263 can be vacuumed, thereby enabling the second dust hood 262 to perform vacuuming through the second vacuum port, and the third dust hood 263 to perform vacuuming through the third vacuum port. The shape of the first lifting base 243 is not limited. The first lifting base 243 is provided with an opening structure for the second and third vacuum ports, so that wood chips, dust, etc. near the second tool 220 can flow into the second dust hood 262 through the second vacuum port, and wood chips, dust, etc. near the third tool 230 can flow into the third dust hood 263 through the third vacuum port, thereby preventing wood chips and dust from being scattered during the wooden door processing operation, which would deteriorate the working environment.

[0060] In this embodiment, the second vacuum port is located on the upper surface of the second dust hood 262, and the third vacuum port is located on the upper surface of the third dust hood 263. Furthermore, a transfer dust hood 261 is provided on the first lifting base 243. The transfer dust hood 261 has two dust inlets and one dust outlet. The two dust inlets are connected to the second and third vacuum ports, respectively, via pipes, and the dust outlet is connected to the vacuum equipment via a pipe.

[0061] In some embodiments, as Figure 3 、 Figure 7 and Figure 8 As shown, the automatic tool changing assembly 300 also includes a fourth drive member 343 and a second pressure plate 341. The second pressure plate 341 is used to press down on the wooden door when machining the door lock hole. The second pressure plate 341 is provided with a first through-hole, which extends from top to bottom and is used to pass through the first tool 320. The first through-hole is coaxial with the first tool 320. The fourth drive member 343 is fixedly mounted on the second lifting platform 332 and can rise and fall with the second lifting platform 332. The output end of the fourth drive member 343 is fixedly connected to the second pressure plate 341. When the fourth drive member 343 is in operation, the output end of the fourth drive member 343 can drive the second pressure plate 341 to move in the vertical direction. The lower surface of the second pressure plate 341 is provided with a second air outlet, and there are multiple second air outlets. The multiple second air outlets are arranged in a matrix arrangement or a circumferential arrangement. The second pressure plate 341 is provided with a second air cavity, and the second air cavity is connected to the multiple second air outlets, so that the gas in the second air cavity can flow out through the multiple second air outlets.

[0062] It is understood that the fourth drive member 343 can be a linear drive device such as an electric cylinder, a pneumatic cylinder, a hydraulic cylinder, or a linear module. In this embodiment, the fourth drive member 343 is a telescopic pneumatic cylinder, two of which are provided and spaced apart along the first direction. Two connecting plates 344 are provided above the second pressure plate 341. The two connecting plates 344 are spaced apart along the first direction. The movable rods of the two fourth drive members 343 are fixedly connected to the two connecting plates 344, respectively, thereby driving the connecting plates 344 to move the second pressure plate 341 upward and downward. The second pressure plate 341 can be a square plate. The second pressure plate 341 is provided with a second air inlet connected to the second air cavity. The second air inlet can be connected to an air supply device via a pipeline. The second pressure plate 341 is configured to blow air onto the upper surface of the wooden door when the second pressure plate 341 is about to press down on the wooden door to remove wood chips and dust.

[0063] During the lock hole machining process, the wooden door is placed on the air-floating platform and held in place by a clamping manipulator. Driven by the clamping manipulator, the wooden door can move back and forth along the second direction on the air-floating platform. During the lock hole machining process, the fourth driving member 343 drives the second pressing plate 341 downward, exerting downward pressure on the upper surface of the wooden door, ensuring that the wooden door remains stable during the lock hole machining process, thereby ensuring high machining accuracy.

[0064] Before the second pressing plate 341 contacts and compresses the wooden door, it ejects air downward to remove impurities such as dust and sawdust from the upper surface of the door, preventing scratches on the upper surface caused by impurities such as sawdust and dust. During this continuous air ejection, the second pressing plate 341 applies a contactless downward pressure to the door through air pressure, preventing scratches when the door moves in the second direction relative to the second pressing plate 341. After the second pressing plate 341 compresses the door, the first tool 320 rotates at high speed to machine the lock hole in the door.

[0065] Further, such as Figure 3 、 Figure 7 、 Figure 8 As shown, the automatic tool changing assembly 300 also includes a first dust hood 342. A second through hole 345 is provided on the upper and lower surfaces of the first dust hood 342. The second through hole 345 runs through the upper and lower surfaces and is used to allow the first tool 320 to pass through. Furthermore, the second through hole 345 is coaxially arranged with the first tool 320 and the first through hole. The first dust hood 342 is arranged between the drive motor 310 and the second pressure plate 341, so that the second through hole 345 is connected to the first through hole. Furthermore, the first dust hood 342 is fixedly connected to the second pressure plate 341. The first dust hood 342 can rise and fall with the second pressure plate 341. A first vacuum port is provided on the side of the first dust hood 342. A circular surface 311 is provided on the periphery of the output end of the drive motor 310. The central axis of the circular surface 311 extends in the vertical direction. The circular surface 311 is fitted against the inner circumference of the second through hole 345 and is slidably connected up and down.

[0066] It is understood that when the fourth driving member 343 drives the second pressure plate 341 and the first dust hood 342 to move upward, the circumferential surface 311 located at the periphery of the output end of the driving motor 310 can simultaneously fit and contact the inner circumferential surface of the first through hole and the inner circumferential surfaces of the two through holes, thereby blocking the first through hole and the second through hole 345. When the fourth driving member 343 drives the second pressure plate 341 and the first dust hood 342 to move downward, the circumferential surface 311 located at the periphery of the output end of the driving motor 310 can fit and contact the inner circumferential surface of the second through hole 345 located on the upper side, thereby blocking the second through hole 345 located on the upper side. At this time, the first through hole and the second through hole 345 located on the lower side are both in an open state, and the second through hole 345 located on the lower side is set as the first dust suction port, which is connected to the first through hole.

[0067] The first vacuum port can be connected to a vacuuming device via a pipe. When the vacuuming device is in operation, it can evacuate the interior of the first dust hood 342, thereby prompting the first dust hood 342 to collect dust through the first dust port. The specific shape of the first dust hood 342 is not limited. After the second pressure plate 341 applies downward pressure to the wooden door, the first dust hood 342 can suction wood chips generated during the door lock hole processing, allowing the wood chips to enter the first dust hood 342 through the first through hole and the first dust port.

[0068] In this embodiment, a felt piece is provided on the upper portion of the first dust hood 342, and the felt piece is arranged around the second through hole 345 located on the upper side. The felt piece can contact the circumferential surface 311 outside the output end of the drive motor 310, thereby improving the sealing effect and preventing wood chips from leaking from the gap between the second through hole 345 located on the upper side and the circumferential surface 311 outside the output end of the drive motor 310.

[0069] Furthermore, Figure 1 、 Figure 3 and Figure 9 As shown, the drilling and milling mechanism based on the wooden door processing technology further includes a dust collection box 510, a fifth driving member 520, and a baffle 530. The dust collection box 510 has a cavity, and is provided with an air outlet 511 and a plurality of air inlets 512. The air outlet 511 is used to be connected to a vacuuming device through a pipeline, and the plurality of air inlets 512 are respectively connected to a first vacuuming port, a second vacuuming port, and a third vacuuming port through pipelines. The air outlet 511 and the plurality of air inlets 512 are respectively connected to the cavity.

[0070] A plurality of baffles 530 are disposed within the cavity, and are arranged vertically opposite the plurality of air inlets 512. The baffles 530 are used to open and close the air inlets 512. A plurality of fifth driving members 520 are provided, and are arranged in a one-to-one correspondence with the plurality of baffles 530. The output end of the fifth driving member 520 is fixedly connected to the baffle 530. When the fifth driving member 520 is in operation, the output end of the fifth driving member 520 can drive the baffle 530 to move vertically, thereby controlling the opening and closing of the air inlets 512.

[0071] It is understood that the fifth drive member 520 can be a linear drive device such as a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder. The fifth drive member 520 can be disposed within the cavity of the dust collection box 510 or outside the cavity of the dust collection box 510. In this embodiment, the fifth drive member 520 is a telescopic pneumatic cylinder, the movable rod of which extends downward into the cavity and is fixedly connected to the baffle 530. The shape of the baffle 530 is compatible with the shape of the air inlet 512. If the air inlet 512 is circular, the baffle 530 is a circular plate.

[0072] When the first dust hood 342 is needed to work, the second dust hood 262 and the third dust hood 263 are in a stopped state. By starting the corresponding fifth drive member 520 to drive the baffle 530 to move upward, the corresponding air inlet 512 is switched from a closed state to an open state, so that the interior of the first dust hood 342 is connected to the cavity of the dust box 510, allowing the vacuuming equipment to vacuum the first dust hood 342, facilitating the first dust hood 342 to perform dust collection. Correspondingly, when the second dust hood 262 or the third dust hood 263 needs to work, the corresponding fifth drive member 520 is started to control the corresponding air inlet 512 to open. Such a design can improve the dust collection effect and avoid all the air inlets 512 being in an open state, which leads to a reduction in the dust collection effect.

[0073] like Figures 1 to 10 As shown, the control method of the drilling and milling processing mechanism based on the wooden door processing technology according to the second embodiment of the present invention is applied to the drilling and milling processing mechanism based on the wooden door processing technology according to the first embodiment, and the control method includes the following steps: Step S11: When the wooden door is placed on the air-floating platform and can move along the second direction, the automatic tool changing assembly 300 and the two-axis motion assembly are enabled, the processing position of the first tool 320 is adjusted, and the door lock hole is processed on the upper surface of the wooden door by the first tool 320, wherein the door lock hole is located on the side of the wooden door away from the horizontal milling groove assembly 200 along the first direction.

[0074] Step S12: When the door lock hole processing is completed, the horizontal milling groove assembly 200 and the two-axis motion assembly are activated to drive the second tool 220 to move along the first direction toward the direction close to the first tool 320, adjust the processing position of the second tool 220, and use the second tool 220 to process a hinge groove on the side of the wooden door away from the door lock hole along the first direction.

[0075] Step S13: When the hinge groove processing is completed, activate the horizontal milling assembly 200 and the two-axis motion assembly, drive the third tool 230 to move along the first direction toward the direction close to the first tool 320, adjust the processing position of the third tool 230, and use the third tool 230 to process the door lock groove on one side of the wooden door along the first direction close to the door lock hole.

[0076] During the processing of the door lock hole, hinge slot and door lock slot of the wooden door, the two-axis motion component is driven to move in the same direction along the first direction to adjust the processing positions of the first tool 320, the second tool 220 and the third tool 230 in the first direction in sequence, so that the door lock hole, hinge slot and door lock slot are processed in sequence on the wooden door. Therefore, the total processing stroke can be reduced, thereby improving the processing efficiency and saving electric energy, and effectively avoiding the two-axis motion component being driven back and forth along the first direction to increase the total processing stroke, thereby reducing the processing efficiency.

[0077] Moreover, the door lock hole is first manufactured through the above steps. When a deep door lock groove is manufactured on the side of the wooden door close to the door lock hole along the first direction, not only can the wood chips generated be discharged by the third tool 230, but the wood chips generated can also be discharged outward through the door lock hole, thereby improving the chip removal efficiency and ensuring the high processing accuracy of the door lock groove.
