[0026] During the processing of wooden doors, lock holes, hinge holes, and decorative patterns need to be machined on the door panels. Lock-hole machines are a crucial piece of woodworking machinery, primarily used for processing wooden doors, door frames, window frames, window sash grooves, door locks, door lock steps, and door lock hinges in one operation. They are used for milling and drilling grooves and holes in the flat surfaces and sides of wooden doors, and can also be used for grooving and drilling in wooden furniture. They provide convenient and precise control over the processing requirements of door lock grooves and hinges. During the processing of wooden doors, the width of the door panel needs to be measured first. Currently, the door panel width is measured manually before being placed on the processing equipment. This method is not only inefficient and inaccurate, but also inevitably generates a large amount of debris during the processing of wooden workpieces. If this debris is not handled promptly, it will not only affect the quality of milling and drilling but also cause environmental pollution and contamination of the lock-hole machine's work surface, making subsequent cleaning very difficult.

[0027] For example, existing keyhole machines use floating dust collection devices for dust collection. Among these, most of the existing floating dust collection devices are independent, which is costly; the existing floating dust collection devices have poor dust collection effect; and the existing floating dust collection devices have a complicated structure and are not easy to adjust, etc.

[0028] In this embodiment of the invention, the first direction is along the X direction in the figure, the second direction is along the Y direction in the figure, and the third direction is along the Z direction in the figure. The front, back, left, and right directions in this invention are along the front, back, left, and right directions in the figure.

[0029] In this embodiment, a keyhole machine includes a frame 100. A support roller assembly 200 is provided at one end of the left side of the upper surface of the frame 100. A fixed platform assembly 300 and a movable platform assembly 400 are respectively installed on the upper surface of the frame 100 from front to back along a first direction. A first processing assembly 500 and a second processing assembly 600 that move along the first direction are respectively movably installed on the front and rear sides of the frame 100. A cantilever arm 700 located above the frame 100 and distributed along a second direction is mounted on the second processing assembly 600. A pusher assembly 800 for positioning and measuring the length of the wooden board to be processed is installed on the left side of the cantilever arm 700. A retractable automatic lateral sensing positioning and retraction assembly 900 for positioning and measuring the length of the wooden board is installed on the right side of the fixed platform assembly 300 near the movable platform assembly 400.

[0030] In one or more possible embodiments of the present invention, the frame 100 is a conventional design. Slide rails are installed on both the front and rear ends of the frame 100, which can move in conjunction with the corresponding sliders installed in the first processing component 500 and the second processing component 600, respectively. As shown in the accompanying drawings, two sets of slide rails distributed along the first direction are installed at the front and rear of the frame 100, and a rack installed on the frame 100 and distributed along the first direction is also provided between the two slide rails on the same side. The rack can be connected to the first transmission mechanism in the first processing component 500 and the second processing component 600, such as a motor, and a gear meshing with the rack to realize the reciprocating motion of the first processing component 500 and the second processing component 600 along the first direction to adapt to the processing of the wood board.

[0031] Meanwhile, the accompanying drawings of this invention also disclose conventional features such as drag chain plates mounted on the frame 100 and limiting blocks set at both ends of the rack, which will not be described in detail here.

[0032] In one or more possible embodiments of the present invention, a support roller assembly 200 for supporting wooden boards is installed on the left side of the upper surface of the frame 100. As can be seen from the accompanying drawings, the support roller assembly 200 includes two sets of roller support plates symmetrically mounted on the upper surface of the frame 100. Two sets of rollers distributed along a second direction are strung between the two roller support plates, which facilitates the transition of wooden boards from the previous wooden board processing step to the present device to complete the processing of the wooden boards.

[0033] In one or more possible embodiments of the present invention, the fixed platform assembly 300 includes a fixed vacuum adsorption assembly 310 and a fixed lifting and conveying assembly 320. The fixed vacuum adsorption assembly 310 includes a fixed support base plate 311 mounted on the frame 100 by a plurality of fixed support columns 312 and horizontally arranged along a first direction. A first vacuum adsorption member 313 is provided at one end of the upper surface of the fixed support base plate 311, and a plurality of second vacuum adsorption members 314 are provided on one side of the first vacuum adsorption member 313 and evenly distributed on the fixed support base plate 311.

[0034] The fixed vacuum adsorption component 310 uses vacuum adsorption to adsorb the wood board and stabilize its position for processing. Before adsorbing the wood board, the wood board needs to be transported from the support roller assembly 200 and lowered onto the vacuum adsorption component (including the fixed vacuum adsorption component 310 in the fixed platform assembly 300 and the movable vacuum adsorption component 410 in the movable platform assembly 400) by a lifting and conveying component (including the fixed lifting and conveying component 320 in the fixed platform assembly 300 and the movable vacuum adsorption component 410 in the movable platform assembly 400) to achieve adsorption of the wood board.

[0035] The fixed lifting and conveying assembly 320 includes two sets of L-shaped mounting plates 321 respectively installed on both ends of the rear side of the fixed support base plate 311. The bottom of each of the two L-shaped mounting plates 321 is equipped with a lifting push rod 322. The telescopic ends of the two lifting push rods 322 are respectively connected to the conveying component 323 through the lifting mounting seat. The bottom of each of the two lifting mounting seats is equipped with a guide shaft 324 that passes through the bottom of the L-shaped mounting plate 321. Thus, by lifting and lowering the lifting push rods 322, the conveying component 323 is driven to lift and lower, thereby realizing the conveying of the wooden board.

[0036] The conveying component 323 is a conventional conveying unit in the art, and its structure will not be described in this invention.

[0037] In this invention, a mobile platform assembly 400 is also disclosed. The mobile platform assembly 400 includes a mobile vacuum adsorption assembly 410, a mobile lifting and conveying assembly 420, and a reciprocating moving assembly 430 that drives the mobile vacuum adsorption assembly 410 and the mobile lifting and conveying assembly 420 to reciprocate along a second direction. The structures of the mobile vacuum adsorption assembly 410 and the mobile lifting and conveying assembly 420 are symmetrical to the fixed vacuum adsorption assembly 310 and the fixed lifting and conveying assembly 320 in the fixed platform assembly 300. Therefore, the structures of the mobile vacuum adsorption assembly 410 and the mobile lifting and conveying assembly 420 will not be described in this invention. This embodiment only illustrates the structure of the reciprocating moving assembly 430.

[0038] The reciprocating moving assembly 430 includes a reciprocating drive unit 431 and several first guide rails 432 distributed along a second direction. Each first guide rail 432 is movably mounted with a first slider 433, and each first slider 433 is connected to a movable support column in the movable vacuum adsorption assembly 410. The reciprocating drive unit 431 includes a reciprocating drive push rod, and the telescopic end of the reciprocating drive push rod is connected to a reciprocating limiting block 434 installed at the bottom of the movable support column. The telescopic movement of the reciprocating drive push rod drives the reciprocating limiting block 434. The mobile vacuum adsorption assembly 410 is moved in the second direction, and the mobile lifting conveyor assembly 420 is also moved in the second direction to adapt to the processing of wooden boards of different widths. In order to further ensure the stable operation of the mobile vacuum adsorption assembly 410 and the mobile lifting conveyor assembly 420, the frame 100 is also equipped with a reciprocating limiting optical axis assembly 435 that cooperates with the reciprocating limiting block 434. The reciprocating limiting optical axis assembly 435 further enhances the stability of the mobile vacuum adsorption assembly 410 and the mobile lifting conveyor assembly 420 in the second direction.

[0039] In one or more possible embodiments of the present invention, the first processing assembly 500 includes a first housing 510, the top of the first housing 510 is provided with a processing component 520 that moves in a second direction, the rear side of the first housing 510 is connected to a processing fixing plate 540 mounted on a frame 100 via a slide rail slider assembly, the processing fixing plate 540 is equipped with a first processing lifting cylinder 530, the telescopic end of the first processing lifting cylinder 530 is connected to the first housing 510 via a first processing connecting block, and the first housing 510 is moved upward in a third direction by the first processing lifting cylinder 530.

[0040] As one embodiment of the processing component 520, the processing component 520 includes a first processing unit 521 and a second processing unit 522. The first processing unit 521 includes a first processing motor 5211. The bottom of the first processing motor 5211 is mounted on a first slide rail slider assembly via a first processing base 5213. The first slide rail slider assembly is mounted on a first housing 510. A first processing electric push rod 5212 is provided on the front side of the first processing motor 5211 and mounted on the first housing 510. The telescopic end of the first processing electric push rod 5212 is connected to the first processing base 5213. Thus, the first processing motor 5211 is driven to reciprocate in a first direction by the first processing electric push rod 5212.

[0041] The second processing unit 522 includes a second processing motor 5221. The bottom of the second processing motor 5221 is mounted on the second slide rail slider assembly via a second processing base. The second slide rail slider assembly is mounted on the first housing 510. A second processing electric push rod 5222 is provided on the front side of the second processing motor 5221 and mounted on the second housing. The telescopic end of the second processing electric push rod 5222 is connected to the second processing base. Thus, the second processing motor 5221 is driven to reciprocate in the first direction by the second processing electric push rod 5222.

[0042] In this embodiment, both the first processing unit 521 and the second processing unit 522 are equipped with dust-collecting isolation covers. The dust-collecting isolation covers are conventional technologies used in the art. During specific processing, a first processing tool is connected to the output end of the first processing motor 5211, and a second processing tool is connected to the output end of the first processing motor 5211 to process the wooden board.

[0043] Referring to the accompanying drawings, a first transmission mechanism for driving the first housing 510 to move in a first direction is also installed on one side of the first housing 510. As mentioned above, the first transmission mechanism cooperates with the rack on the frame 100 to drive the first processing component 500 to reciprocate along the first direction on the frame 100.

[0044] In one or more embodiments of the present invention, the second processing component 600 includes a first horizontal processing unit 610, a second vertical processing unit 620, and a third front and rear processing unit 630, which are arranged in sequence from back to front.

[0045] The second vertical processing unit 620 includes a second lifting servo motor 621. The second lifting servo motor 621 is mounted on one side of the fixed plate via a cylinder seat set on the top of the fixed plate. The second lifting servo motor 621 is connected to a lead screw 622 distributed along the third direction via a coupling. The other end of the lead screw 622 is connected to a nut seat mounted on the outer side of the second Z-axis slide plate 623. The second Z-axis slide plate 623 is connected to the fixed plate via a slide seat. Several sets of Z-axis processing components 624 are mounted on the other side of the second Z-axis slide plate 623.

[0046] The Z-axis machining component 624 includes a main spindle slide plate 6241 that movably engages with a second Z-axis slide plate 623 via a slide block. The upper part of the main spindle slide plate 6241 is connected to a Z-axis cylinder 6242 mounted on the second Z-axis slide plate 623 via a cylinder connecting seat. A vertically downward-oriented Z-axis machining motor 6243 is mounted on the main spindle slide plate 6241 via a main spindle back plate. Two sets of dust hood guide shaft seats 6244 are symmetrically mounted on two opposite sides of the main spindle slide plate 6241. A Z-axis optical axis 6245 is installed between the corresponding two sets of dust hood guide shaft seats 6244. The bottom end of each Z-axis optical axis 6245 is connected to a Z-axis floating dust hood 6246. A short compression spring and a long compression spring are respectively sleeved on the outside of each Z-axis optical axis 6245. The long compression spring is located on the Z-axis floating dust hood. Between 6246 and the lower dust hood guide shaft seat 6244, a short compression spring is set between the two dust hood guide shaft seats 6244. The upper part of the Z-axis optical shaft 6245 is provided with an optical shaft fixing ring 6247 for controlling the static deformation of the spring. In this way, the Z-axis machining motor 6243 is controlled to move up and down by the extension and retraction of the Z-axis cylinder 6242 to adapt to the processing of wood boards of various thicknesses. The Z-axis optical shaft 6245 is connected to the Z-axis floating dust hood 6246. The net size of the rubber ring pressure plate of the Z-axis floating dust hood 6246 and the tool on the Z-axis machining motor 6243 is adjusted to ensure that the wood dust at the tool can be sucked away during processing. After the adjustment is completed, the optical shaft fixing ring 6247 is locked to the optical shaft with bolts to control the static deformation of the spring and achieve floating adjustment.

[0047] In this embodiment, the first horizontal processing unit 610 includes a first front axle base plate 611. Horizontal spindle slide plates 612 are respectively mounted on the left and right sides of the first front axle base plate 611 via slide blocks. X-axis processing components 613 for horizontally processing the rear side of the wooden board are respectively mounted on the two horizontal spindle slide plates 612. A width-measuring cylinder 614 that extends and retracts in a first direction is mounted at the bottom front end of the first front axle base plate 611. A width-measuring travel switch 615 is mounted on the extension end of the width-measuring cylinder 614 via a travel switch bracket. A thickness measuring cylinder 616 that extends and retracts in a third direction is installed on the lower left side of the bearing plate 611. The extension end of the thickness measuring cylinder 616 is equipped with a thickness measuring limit switch 617 through a limit switch bracket. This enables horizontal processing of the wooden board, as well as thickness and width measurement of the wooden board. In this embodiment, the first front bearing plate 611 is connected to the rear side of the second Z-axis slide plate 623 through a vertical bearing plate, so that the first horizontal processing unit 610 can move in the vertical direction under the control of the second lifting servo motor 621 to adapt to the processing of the wooden board.

[0048] In this embodiment, the third front-end and rear-end processing unit 630 includes a double-head spindle plate 631 that is connected to the second Z-axis slide plate 623. The front side of the double-head spindle plate 631 is connected to the double-head spindle slide plate 632 via a slide block. A vertical telescopic cylinder 633 is installed on the top of the double-head spindle plate 631. The telescopic end of the vertical telescopic cylinder 633 is connected to the rear side of the double-head spindle slide plate 632 via a cylinder connecting block. A double-head spindle motor 634 arranged along the first direction is installed on the lower part of the front side of the double-head spindle slide plate 632. Two sets of parallel-positioned motors are symmetrically installed on the front side of the double-head spindle slide plate 632. Above the dual-head spindle motor 634, on the linear bearing seat 635, two sets of floating adjustment shafts 637 are respectively installed between the two linear bearing seats 635, extending to both sides and connected to the end face floating dust collection cover 636. This allows them to cooperate with the dual-head spindle motor 634. When the dual-head spindle motor 634 is equipped with the corresponding processing tool to process the wood board, the net dimensions of the end face floating dust collection cover 636 and the dual-head spindle tool can be calculated according to the hole depth at the front and rear ends of the wooden door. This ensures that the tool can reach the turning hole depth, while the end face floating dust collection cover 636 is always in contact with the processing end face of the wooden door to prevent sawdust from leaking out.

[0049] In this embodiment, the floating adjustment shaft 637 includes two sets of horizontally arranged X-axis optical shafts 6371 that cooperate with linear bearing seats 635. The end of the X-axis optical shaft 6371 is connected to the end face floating dust collection cover 636 located on one side of the dual-head spindle motor 634. A long compression spring is sleeved on the outer circumference of the X-axis optical shaft 6371 and between its end and the adjacent linear bearing seat 635. A short compression spring is sleeved on the outer circumference of the X-axis optical shaft 6371 between the two linear bearing seats 635. In specific applications, the retraction amount of the compression spring is initially set according to the calculated theoretical value. Then, based on the processing effect, the deviation value of the actual hole depth is verified with the theoretical value. On this data, the retraction amount of the compression spring is finely adjusted again until the processing hole depth effect value meets the processing requirements and is within a reasonable tolerance.

[0050] The floating dust collection hoods in each of the above processing units are connected to the dust collection components via flexible hoses. The dust collection components are connected to the negative pressure device via pipes to remove wood chips from the wood processing area. The attached drawings of this embodiment disclose a dust collection component (not marked in the figure, which is a concave structure), located on the upper part of the first horizontal processing unit 610, the second vertical processing unit 620, and the third front and rear processing unit 630.

[0051] In conjunction with the above, the processing of the rear side, top surface, and front and rear end faces of the wooden board is achieved through the first horizontal processing unit 610, the second vertical processing unit 620, and the third front and rear processing unit 630, as well as floating dust removal. This ensures that the floating dust suction cover 636 is always in contact with the processing end face of the wooden door to prevent wood chips from leaking out. In addition, it can be used to measure the width and thickness of the wooden board.

[0052] In this embodiment, the side of the fixed plate near the cantilever arm 700 is also equipped with a slider that cooperates with the slide rail set along the second direction on the cantilever arm 700, and a drive mechanism for driving the second processing component 600 to move in the second direction is provided. The attached drawings of this embodiment show that the top of the cantilever arm 700 is provided with a rack, and the drive mechanism includes a servo drive motor. The output end of the servo drive motor is provided with a gear that cooperates with the rack. By driving the gear through the servo drive motor, the second processing component 600 can reciprocates along the second direction on the cantilever arm 700.

[0053] In one or more possible embodiments of the present invention, a push assembly 800 for positioning and measuring the length of the wooden board to be processed is installed on the left side of the cantilever arm 700. The push assembly 800 includes a push mounting plate 810 mounted on the cantilever arm 700. A push cylinder 830 is mounted on the lower part of the push mounting plate 810 via a push lifting cylinder seat 820. The telescopic end of the push cylinder 830 is connected to a push cylinder seat 840. A push cylinder 850 is installed at the bottom of the push cylinder seat 840. The telescopic end of the rear push cylinder 850 is equipped with several rubber pressure rollers 860 via a side push roller mounting plate. A miniature cylinder 870 is provided on one side of the rear push cylinder 830, and a limit switch is installed at the telescopic end of the miniature cylinder 870. In specific applications, the rear push assembly 800 needs to cooperate with other components of this device. Specifically, when the wooden door moves forward and passes the diffuse reflection photoelectric sensor on the fixed platform assembly 300, the cantilever beam is immediately reset to the origin of the loading platform. When the wooden door continues to move forward to the front positioning group of the machine body... When the diffuse reflection photoelectric sensor of the component is activated, the lifting and conveying assembly immediately stops operating and lowers, placing the wooden door onto the vacuum adsorption sponge of the fixed platform assembly 300 and the moving platform assembly 400. Simultaneously, the cantilever beam moves rapidly from back to front, and the pushing cylinder 830 of the rear pushing device extends a certain distance, centering the rubber pressure roller 860 with the thickness of the wooden door. Then, the limit switch at the output shaft of the micro cylinder 870 extends forward. When the contact of the limit switch touches the wooden door, the micro cylinder 870 immediately retracts and completes the counting. The system records the position of the cantilever beam when the contact point is made. The difference between the recorded value and the position value of the diffuse reflection photoelectric sensor of the automatic side-sensing positioning shrinkage assembly 900 is used to obtain the total length of the wooden door, realizing the length measurement function. As the cantilever beam moves forward, the rubber pressure roller 860 of the rear pushing device pushes the wooden door forward until the front end of the wooden door touches the contact of the micro switch 940 of the automatic side-sensing positioning shrinkage assembly 900. At this moment, the cantilever beam immediately stops moving forward and the wooden door is positioned.

[0054] Specifically, the automatic lateral sensing positioning and retraction assembly 900 includes a positioning mounting plate 910 mounted on the fixed platform assembly 300. A slanted positioning assembly seat 920 is mounted on the front side of the positioning mounting plate 910. A slanted positioning block 930 is connected to the left side of the slanted positioning assembly seat 920 via a slide block. A micro switch 940 is mounted on the upper left end of the slanted positioning block 930, and a positioning block cooperating with the micro switch 940 is mounted on the upper right end of the slanted positioning block 930. A positioning telescopic cylinder 960 is mounted on the bottom of the slanted positioning assembly seat 920 via a positioning clamping mounting plate 950. The telescopic end of the positioning telescopic cylinder 960 is connected to the bottom of the inclined positioning block 930. A diffuse reflection photoelectric sensor 970 is installed on the upper right end face of the inclined positioning component seat 920. The inclined positioning block 930 of the automatic side-sensing positioning retraction component 900 is parallel to the inclined positioning component seat 920 and both form an 85° angle with the conveyor belt platform.
