The horizontal drilling, gluing, and tenoning machine also includes at least one integrated drilling and tenoning device movably connected to the frame. The integrated drilling and tenoning device moves relative to the board along a first axis via a first driving mechanism, and moves relative to the board thickness along a second axis via a second driving mechanism.

Description

Technical Field

[0001] This utility model belongs to the field of sheet metal processing technology, and in particular relates to a horizontal drilling, gluing and tenoning machine. Background Technology

[0002] In existing technologies, drilling, gluing, and tenoning equipment for furniture board processing pre-sets the positions for drilling and tenoning before performing the drilling and tenoning. Although this method can meet the processing requirements to a certain extent, drilling, gluing, and tenoning are three different pieces of equipment, resulting in limited functionality and lower efficiency. Utility Model Content

[0003] The purpose of this utility model is to address the above-mentioned problems by providing a horizontal drilling, gluing, and tenoning machine that can solve the aforementioned technical issues.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A horizontal drilling, gluing, and tenoning machine includes a frame, on which at least one board positioning component is provided, and a pressing mechanism for fixing the board placed on the board positioning component. The horizontal drilling, gluing, and tenoning machine also includes at least one drilling and tenoning integrated device movably connected to the frame. The drilling and tenoning integrated device moves relative to the board along a first axis direction via a first driving mechanism, and moves relative to the board thickness direction along a second axis direction via a second driving mechanism. The drilling and tenoning integrated device includes adjacent drilling mechanisms and tenoning mechanisms.

[0005] Furthermore, the first driving mechanism is any one of a lead screw driving mechanism, a rack and pinion driving mechanism, and a pulley driving mechanism.

[0006] Furthermore, the second drive mechanism is any one of a servo electric cylinder drive mechanism, a hydraulic cylinder drive mechanism, and a linear drive mechanism.

[0007] Furthermore, the second drive mechanism includes a second driver and an auxiliary balancing driver distributed in parallel with the second driver.

[0008] Furthermore, the drilling and tenoning integrated device also includes a sliding side plate that is slidably connected to the frame and moves along the first axis direction under the drive of the first drive mechanism. A lifting sliding frame that moves in the second axis direction is slidably connected to the sliding side plate. The second drive mechanism drives the lifting sliding frame to move. The drilling mechanism and the tenoning mechanism are respectively disposed on the lifting sliding frame.

[0009] Furthermore, the drilling mechanism includes a drilling base slidably connected to the lifting sliding frame on a third axis, the drilling base being connected to a linear drive assembly, and 1-N drill bit holders being provided on the drilling base, each of the drill bit holders being connected to a drill bit rotary driver.

[0010] Furthermore, the tenoning mechanism includes a tenoning seat with a horizontal discharge channel, a tenoning feed channel that is angularly distributed with the horizontal discharge channel on the tenoning seat, and a tenoning push rod located behind the connection between the horizontal discharge channel and the tenoning feed channel in the horizontal discharge channel, the tenoning push rod being connected to a linear driver.

[0011] Furthermore, the tenon feeding channel and the horizontal discharge channel are distributed at an acute angle, and the tenon feeding channel is connected to the vibrating material tray through a conveying pipe. A tenon discharge control cylinder is provided on the horizontal discharge channel or the conveying pipe.

[0012] Furthermore, the tenoning mechanism also includes a side glue injection assembly, wherein the glue injection needle of the side glue injection assembly and the horizontal discharge channel are distributed at an acute angle, and the glue injection needle and the glue injection needle driver are connected.

[0013] Furthermore, the plate positioning assembly includes a plurality of positioning references distributed along the first axis and the third axis on the placement platform, and at least two adjacent sides of the plate are in contact with the positioning references; the pressing mechanism includes a plurality of pressing blocks that move axially along the second axis, and pressing drivers connected to each of the pressing blocks.

[0014] Compared with existing technologies, the advantages of this application are: it achieves precise centering control of the drilling position in the thickness direction of the sheet material. By driving the integrated drilling and tenoning device to move as a whole along the thickness direction, the mechanism can adjust the starting height of the drill bit according to the real-time thickness or preset requirements of each sheet material, ensuring that the drilling axis is always located on the geometric center line of the sheet material thickness. This effectively solves the problem of hole position being too high or too low due to uneven sheet material thickness, thus making it applicable to the processing of sheets of different thicknesses.

[0015] The integrated drilling and tenoning device is integrated into one unit, which can improve production efficiency and make the whole machine more compact. Attached Figure Description

Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0019] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0021] In the description of this embodiment, the terms "upper," "lower," "right," and "left," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0022] In this embodiment, the Y-axis is a direction perpendicular to the ground, and the Z-axis and X-axis are directions perpendicular to the Y-axis, respectively. Example 1

[0023] like Figures 1-3 As shown, this horizontal drilling, gluing, and tenoning machine includes a frame 1 as a framework, at least one plate positioning assembly 2 on the frame 1, and a pressing mechanism 4 for fixing the plate 3 placed on the plate positioning assembly 2. The plate positioning assembly 2 includes a plurality of positioning references 21 distributed along the first axis X and the third axis Z on the frame 1, generally 2-N, for example 4. At least two adjacent sides of the plate 3 are in contact with the positioning references 21. The pressing mechanism 4 includes a plurality of pressing blocks 41 that move along the second axis Y, and pressing drivers 42 connected one by one to the plurality of pressing blocks 41.

[0024] When the equipment is working, the operator or the automatic feeding device places the sheet material 3 to be processed on the frame 1 of the sheet material positioning component 2, ensuring that the adjacent edges of the sheet material 3 are in close contact with the corresponding positioning reference 21. Subsequently, the pressure drive 42 drives the pressure block 41 to move downward along the second axis Y direction, firmly pressing the sheet material 3 onto the frame 1 to prevent displacement during processing. In this embodiment, the pressure drive 42 can be any one of a servo electric cylinder drive mechanism, a hydraulic cylinder drive mechanism, and a linear drive mechanism. This embodiment only exemplifies a cylinder-driven pressure drive 42.

[0025] Its special feature is that the horizontal drilling and gluing tenoning machine also includes at least one drilling and tenoning integrated device 5 movably connected to the frame 1. The drilling and tenoning integrated device 5 is an integral structure and is horizontal. The drilling and tenoning integrated device 5 moves relative to the plate 3 along the first axis X direction through the first drive mechanism 6. The drilling and tenoning integrated device 5 moves relative to the thickness direction of the plate 3 along the second axis Y direction through the second drive mechanism 7. The drilling and tenoning integrated device 5 includes a drilling mechanism 51 and a tenoning mechanism 52 that are distributed adjacently.

[0026] Furthermore, the aforementioned horizontal drilling and gluing tenoning machine also includes a sliding side plate 53 that is slidably connected to the frame 1 and moves along the first axis X direction under the drive of the first drive mechanism 6. A lifting sliding frame 54 that moves in the second axis Y direction is slidably connected to the sliding side plate 53. The second drive mechanism 7 drives the lifting sliding frame 54 to move. The drilling mechanism 51 and the tenoning mechanism 52 are respectively disposed on the lifting sliding frame 54.

[0027] Furthermore, the first drive mechanism 6 can be any one of a lead screw drive mechanism, a rack drive mechanism, and a pulley drive mechanism. The second drive mechanism 7 can be any one of a servo electric cylinder drive mechanism, a hydraulic cylinder drive mechanism, and a linear drive mechanism. In this embodiment, the first drive mechanism 6 is a rack drive mechanism, and the second drive mechanism 7 is a servo electric cylinder drive mechanism. As a multiple option, the drive method of the second drive mechanism 7 can also be manually adjustable, such as a lead screw and nut transmission method.

[0028] Specifically, in this embodiment, the first driving mechanism 6 adopts a rack and pinion drive mechanism. This mechanism includes a precision rack fixedly mounted on the frame 1, and a drive gear rotatably connected to the sliding side plate 53 and meshing with the rack. The drive gear is driven by a servo motor. When the motor operates, the drive gear rolls along the fixed rack, thereby precisely driving the entire drilling and tenoning integrated device 5 to perform linear reciprocating motion along the first axis X. The advantages of rack and pinion drive are its relatively simple structure, good rigidity, and ability to achieve stable transmission over long strokes.

[0029] In this embodiment, the second drive mechanism 7 specifically adopts a servo electric cylinder drive mechanism. This mechanism uses a double-acting cylinder as its core actuating element. The cylinder body is fixedly connected to the sliding side plate 53 driven by the first drive mechanism. The end of the cylinder piston rod is rigidly connected to the lifting sliding frame 54. By controlling compressed air, the piston rod and its connected lifting sliding frame 54 are driven to perform linear reciprocating motion along the second axis Y direction.

[0030] like Figure 4 and Figure 7As shown, the second drive mechanism 7 includes a second driver 71 and an auxiliary balance driver 72 that is parallel to the second driver 71. In this embodiment, both the second driver 71 and the auxiliary balance driver 72 are servo electric cylinder drive mechanisms. The second driver 71 and the auxiliary balance driver 72 are respectively located on both sides of the lifting sliding frame 54 and fixed to the sliding side plate 53. Their output ends are respectively fixedly connected to the lifting sliding frame 54. The second driver 71 and the auxiliary balance driver 72 work synchronously and in coordination under the control of a control system (not shown in the figure, and the control system is prior art or directly purchased). When it is necessary to drive the lifting sliding frame 54 to move up and down along the second axis Y direction (i.e., the thickness direction of the plate 3), the second driver 71 and the auxiliary balance driver 72 simultaneously output driving force, directly pushing or pulling the lifting sliding frame 54 through their output ends, thereby driving the entire drilling mechanism 51 and tenoning mechanism 52 fixed on the lifting sliding frame 54 to move smoothly. This dual-drive parallel symmetrical arrangement effectively overcomes the problems of tilting, jamming, or unilateral wear of the lifting sliding frame 54 during movement, which may be caused by the offset of the device's center of gravity or uneven processing forces. The auxiliary balancing drive 72 not only shares the main downward pressure load but also provides symmetrical support and guiding force, ensuring the high linearity and stability of the lifting sliding frame 54 and the drilling and tenoning integrated device 5 it carries in the second axis Y direction. When the second drive 71 outputs driving force (such as cylinder rod extension), the auxiliary balancing drive 72 synchronously outputs driving force of the same direction and magnitude. The two drive 72 share the total load acting on the lifting sliding frame 54, avoiding overload, deformation, or response lag caused by a single drive bearing the majority of the load.

[0031] In this embodiment, the drilling mechanism 51 includes a drilling base 511 slidably connected to the lifting sliding frame 54 on the third axis Z. The drilling base 511 is connected to the linear drive assembly 512, and 1-N drill bit holders 513 are provided on the drilling base 511. In this embodiment, the drill bit holder 513 is a drill bit chuck. In use, a straight shank drill bit is inserted into the inner hole of the chuck, and the inner diameter of the chuck is contracted by tightening the locking nut, thereby firmly and accurately clamping the drill shank. Each drill bit holder 513 is connected to a drill bit rotation driver 514, and several drill bit holders 513 are arranged as follows: Figures 8-9 As shown, the linear drive assembly 512, which is horizontally distributed on the drilling base 511, is primarily responsible for realizing the drilling feed motion. During the drilling process, the linear drive assembly 512 drives the drill bit holder 513 (and the drill bit) to feed perpendicularly to the plate surface (third axis Z) to a preset depth.

[0032] When the equipment is working, after the drilling and tenoning integrated device 5 is positioned at the target processing point by the first drive mechanism 6 and the second drive mechanism 7, the drilling mechanism 51 performs the drilling operation: Single hole machining mode: If only a single tenon hole needs to be machined, the linear drive assembly 512 will drive the drill base 511 to move, so that one of the drill bit holders 513 is precisely aligned with the position of the hole for drilling.

[0033] Multi-hole synchronous processing mode: If multiple tenon holes with fixed spacing need to be processed at one time along the first axis X, the required spacing between drill bits is preset. During processing, the drilling base 511 only needs to be positioned once along the second axis Y, and the drill bit rotation driver 514 simultaneously drives the drill bit to rotate. The first drive mechanism 6 drives the entire device to move along the first axis X, thus completing the drilling of multiple tenon holes simultaneously, significantly improving processing efficiency.

[0034] In this embodiment, the tenoning mechanism 52 includes a tenoning seat 521 with a horizontal discharge channel 5211, a tenoning feed channel 5212 angled to the horizontal discharge channel 5211 on the tenoning seat 521, and a tenoning push rod 5213 located behind the connection between the horizontal discharge channel 5211 and the tenoning feed channel 5212 within the horizontal discharge channel 5211. The tenoning push rod 5213 is connected to a linear driver 522. The tenoning feed channel 5212 and the horizontal discharge channel 5211 are arranged at an acute angle, and the tenoning feed channel 5212 is connected to a vibrating feed pan 8 via a conveying pipe 81. A tenon discharge control cylinder 82 is provided on the horizontal discharge channel 5211 or the conveying pipe 81. There are two tenon discharge control cylinders 82, one in front of the other, to control the single feeding of the tenon into the horizontal discharge channel 5211.

[0035] like Figure 2 As shown, the tenoning mechanism 52 also includes a side glue injection assembly 523, in which the glue injection needle 5231 and the horizontal discharge channel 5211 are distributed at an acute angle, and the glue injection needle 5231 and the glue injection needle driver 5232 are connected.

[0036] The vibrating feeder 8 transports the wooden doves systematically to the dove-feeding channel 5212 via the conveying pipe 81. The dove discharge control cylinder 82 (the rear cylinder) activates first, allowing a single dove to enter the end of the dove-feeding channel 5212 near the point where it connects to the horizontal discharge channel 5211. Subsequently, the rear dove discharge control cylinder 82 closes, and the front dove discharge control cylinder 82 opens, allowing the dove, aided by gravity or slight vibration, to roll or slide into the horizontal discharge channel 5211 through the acute-angled dove-feeding channel 5212, and stop in front of the dove-feeding push rod 5213 (i.e., behind the connection point). Then, the front dove discharge control cylinder 82 also closes, ensuring that only one dove is to be inserted in the horizontal discharge channel 5211. This effectively prevents the doves from stacking or getting stuck in the channel, ensuring precise single-dove feeding. Figure 8As shown, the conveying pipe 81 passes through the through hole in the side upright plate so that the conveying pipe 81 can be distributed at an inclined angle.

[0037] like Figure 9 As shown, when the wooden dove is located in the horizontal discharge channel 5211, the glue injection needle driver 5232 drives the glue injection needle 5231 to move forward along its axial direction (at an acute angle with the horizontal discharge channel), so that its needle tip is accurately inserted into the tenon hole (not shown in the figure) on the side wall of the board 3. The glue injection needle driver 5232 is any one of the servo electric cylinder drive mechanism, hydraulic cylinder drive mechanism and linear drive mechanism.

[0038] A linear actuator 522 (typically a cylinder or electric actuator) drives the dowel insertion rod 5213 forward along the axis of the horizontal discharge channel 5211. The front end of the dowel insertion rod 5213 precisely strikes the tail of the wooden tenon located in front of it, pushing the wooden tenon out of the outlet of the horizontal discharge channel 5211. Under the kinetic energy of the actuator, the wooden tenon is horizontally pressed into the pre-drilled mortise in the plate 3, completing the dowel insertion action. Glue is then injected to firmly place the wooden tenon in the mortise through friction and adhesive bonding.
