[0030] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0031] like Figure 1 and Figure 2 As shown, the furniture manufacturing board drilling device of this application includes several key components that work together to achieve efficient drilling operations. This device is mainly used for drilling furniture boards, and its optimized structural design improves operational efficiency.

[0032] Drill bit 1 is used to perform drilling operations on furniture panels. It is mounted at the front end of drive shaft 2 and can be replaced via quick connector 3. Drill bit 1 is typically made of carbide material, for example, using an indexable insert structure to achieve high-precision hole machining. Technically, drill bit 1 can engage with the connector through a standardized shank design, ensuring stability during high-speed rotation and reducing vibration and wear.

[0033] The drive shaft 2 is used to transmit rotational power to drive the drill bit 1. It is installed in the central area of ​​the base 5 and connected to the base 5 via bearings. The drive shaft 2 is made of high-strength steel and has a hollow channel inside to accommodate the power transmission components. Technically, rotational power can be input via a motor or an external drive source, for example, by using a coupling to couple the motor output shaft to the drive shaft 2, ensuring efficient power transmission to the drill bit 1.

[0034] The quick connector 3 is used to enable quick replacement of the drill bit 1 and is fixedly connected to the end of the drive shaft 2. This connector includes a snap-fit ​​engagement structure 31, which contains a spring-preloaded locking pin 32 (see details). Figure 4 The locking pin 32 is equipped with a manual release lever 33. Structurally, the locking pin 32 is preloaded by a spring mechanism and automatically engages with a groove in the shank of the drill bit 1 when the drill bit 1 is inserted, forming a rigid connection. The manual release lever 33 is located on the side of the connector and is used to release the lock with a single press. Technically, the connector can be implemented using a standard mechanical design, such as using a locking pin 32 made of spring steel and a lever-type release mechanism, to ensure that the drill bit 1 locks instantly during unidirectional insertion and is quickly removed when the release lever is pressed.

[0035] The clamp 4 is used to hold and position the furniture board. It is installed on the worktable of the base 5 and works in conjunction with the guide column 6. The clamp 4 is usually composed of adjustable jaws and positioning blocks. Technically, clamping can be achieved by hydraulic or manual screw mechanisms, such as using a rotating handle to drive the jaws to move, to accommodate boards of different sizes and ensure that the boards are stably positioned during drilling.

[0036] The base 5 supports the drive shaft 2 and the clamp 4. It is mounted at the base of the device and is rotatably connected to the drive shaft 2 via bearings. The base 5 is made of cast iron or aluminum alloy and has an integrated bearing housing. Technically, the connection can be achieved using rolling bearings or sliding bearings, for example, using deep groove ball bearings embedded in the holes of the base 5, allowing the drive shaft 2 to rotate freely while providing overall structural rigidity.

[0037] The guide post 6 is used to guide the drill bit 1 to move vertically and is fixedly connected to the upper part of the base 5. The guide post 6 is usually a cylindrical rod that slides with the drill bit 1 assembly; technically, it can be achieved by a linear bearing or a sliding sleeve structure, for example, by installing a linear bearing on the guide post 6, so that the drill bit 1 can be smoothly pressed down along the vertical path during operation, ensuring drilling accuracy and consistency.

[0038] This feature, through the optimized design of the quick connector 3, effectively solves the technical problem of how to shorten operation time. Specifically, the snap-fit ​​engagement structure 31 of the quick connector 3 allows the drill bit 1 to be instantly locked by a one-way insertion action, without the need for additional tools or complex operations, significantly reducing the time spent changing the drill bit 1; the spring-preloaded locking pin 32 automatically engages with the groove upon insertion, forming a rigid connection and avoiding the tightening time required for traditional threaded connections; at the same time, a single press of the manual release lever 33 can quickly release the lock, enabling immediate removal of the drill bit 1. These designs reduce operation interruption time and improve overall processing efficiency, making them particularly suitable for mass production scenarios that require frequent changes of the drill bit 1.

[0039] like Figure 3As shown, in one embodiment, the drill bit 1 of a furniture manufacturing board drilling device of this application has a standardized interface groove 11 at its end. The shape of the interface groove 11 is designed to precisely match the locking pin 32 of the quick connector 3. The interface groove 11 is located at the end of the insertion end of the drill bit 1, and its structure adopts a standardized geometric profile to ensure a consistent positioning reference during drill bit 1 replacement. Specifically, the size and profile of the interface groove 11 are optimized to achieve a seamless fit with the locking pin 32, thereby eliminating the need for manual alignment.

[0040] The connection design of the interface slot 11 allows for automatic engagement via a unidirectional insertion action. When the drill bit 1 is inserted into the quick connector 3, the guide surface of the interface slot 11 guides the locking pin 32 to slide into the slot. Under the action of the spring preload mechanism, the locking pin 32 automatically engages with the bottom of the slot to form a rigid connection. This arrangement simplifies the positioning process for changing the drill bit 1, requiring only a single push-in action to complete the installation.

[0041] For example, the interface groove 11 can be manufactured in a rectangular or keyway shape, while the locking pin 32 is designed as a columnar structure with a corresponding cross-section. In implementation, the end of the drill bit 1 is machined to form a groove profile, the depth and width of which are complementary to the dimensions of the locking pin 32, so that the locking pin 32 can be compressed and spring into the groove to lock during insertion, ensuring the reliability and speed of the connection.

[0042] A flange 21 is provided at the end of the drive shaft 2, which is used to fix the quick connector 3. This connection method achieves direct installation of the drive shaft 2 and the quick connector 3 through the rigid coupling of the flange 21, ensuring that the rotational power is efficiently transmitted from the drive shaft 2 to the quick connector 3 and avoiding energy loss due to indirect transmission. The flange 21 adopts a bolt-fastening structure, in which the flange 21 is integrated into the end of the drive shaft 2 and is tightly fixed to the corresponding interface of the quick connector 3 by multiple bolts. This design eliminates the gaps in traditional keyway or spline connections, thereby significantly reducing the risk of connection loosening under high-speed rotation conditions. In addition, the standardized interface of the flange 21 simplifies the disassembly process, eliminating the need for complex calibration steps when changing the drill bit 1, and directly shortening the adjustment time.

[0043] like Figure 2 As shown, in one embodiment, the drive shaft 2 of the furniture manufacturing board drilling device of this application is integrated with a flange 21 at its end. The flange 21 is fixedly connected to the base 5 of the quick connector 3 by bolts. For example, the flange 21 is provided with annularly distributed threaded holes, and the quick connector 3 is provided with corresponding through holes. After the bolts pass through the through holes and are screwed into the threaded holes, a rigid connection is formed. Specifically, the flange 21 and the base 5 of the quick connector 3 adopt a flat contact surface design to ensure that the rotational power is directly transmitted and there is no relative displacement.

[0044] like Figure 2As shown, in one embodiment, the main body of the quick connector 3 of the furniture manufacturing board drilling device of this application adopts an integrally formed cylindrical structure 34. This cylindrical structure 34 is directly exposed to the outside of the device, making it convenient for users to operate by hand. Specifically, the cylindrical structure 34 is located in the end area of ​​the drive shaft 2, and its shape is designed as cylindrical or similar, allowing users to grip it directly without the need for additional tools or protective covers. By being exposed to the outside, the cylindrical structure 34 ensures the accessibility of operation, thereby optimizing the convenience of replacing the drill bit 1.

[0045] The cylindrical structure 34 integrates a snap-fit ​​engagement structure 31, resulting in a compact overall layout that reduces operational steps. For example, the inner cavity of the cylindrical structure 34 directly accommodates the snap-fit ​​engagement structure 31, forming a single component and avoiding the assembly complexity caused by scattered parts. This integrated design allows the snap-fit ​​engagement structure 31 to be completely built-in while maintaining the integrity of the cylindrical structure 34, ensuring that only simple actions are required when inserting or removing the drill bit 1, thus improving efficiency.

[0046] Specifically, the cylindrical structure 34 can be integrally cast from metal or high-strength plastic, and has an internal mounting slot for the snap-fit ​​joint structure 31. For example, the snap-fit ​​joint structure 31 is embedded in the inner wall of the cylindrical structure 34. During operation, the user holds the cylindrical structure 34 and inserts the drill bit 1 in one direction. The snap-fit ​​joint structure 31 automatically locks itself in place without the need for multiple adjustments or auxiliary tools.

[0047] The snap-fit ​​engagement structure 31 mainly consists of a locking pin 32 and a single helical spring 35. The locking pin 32, as a key locking element, is configured to automatically engage with the groove in the drill bit 1 shaft when the drill bit 1 is inserted, thereby achieving a rigid connection. The locking pin 32 has an internal receiving cavity, within which the single helical spring 35 is preloaded and fixed, remaining compressed to continuously provide elastic force. This preload mechanism ensures that the locking pin 32 remains in the extended position when not subjected to external force, briefly retracts during drill bit 1 insertion, and then immediately pops out to lock when the grooves are aligned.

[0048] By integrating the helical spring 35 directly into the locking pin 32, the number of components is simplified, eliminating the need for external springs or additional fasteners. The locking pin 32 is typically slidably mounted in the radial hole of the quick connector 3, with its direction of movement perpendicular to the insertion axis of the drill bit 1. One end of the spring abuts against the inner wall of the locking pin 32, while the other end is fixed to the bottom of the hole, forming a stable preloaded connection. This structure reduces the number of moving parts, lowers the risk of jamming, and thus improves the reliability and responsiveness of the locking action.

[0049] like Figure 4As shown, in one embodiment, the snap-fit ​​engagement structure 31 of a furniture manufacturing board drilling device of this application includes a locking pin 32. The locking pin 32 has a cylindrical cavity inside, and a single helical spring 35 is compressed and installed within this cavity, forming a preloaded state. Specifically, the locking pin 32 is slidably disposed in the radial guide hole of the quick connector 3. One end of the spring is fixed to the bottom of the cavity, and the other end abuts against the end wall of the guide hole. When the drill bit 1 is inserted, its tapered end pushes the locking pin 32 radially inward to compress the spring. Once the groove of the drill bit 1 reaches the designated position, the spring pushes the locking pin 32 to automatically engage in the groove, completing the locking. A manual release lever 33 is operably connected to the outside of the locking pin 32 for releasing the locked state by pressing against the spring force.

[0050] The locking pin 32, a key component of the snap-fit ​​engagement structure 31, is installed inside the quick connector 3 to achieve automatic locking during drill bit 1 insertion. The end of the locking pin 32 integrates a tapered guide head 321, designed with a gradually tapering tapered geometry and a smooth surface to reduce the coefficient of friction. When the drill bit 1 is inserted into the quick connector 3, the tapered guide head 321 first contacts the entrance edge of the drill bit 1 interface groove 11. Due to the inclined design of the tapered guide head 321, it guides the locking pin 32 to automatically slide into the interface groove 11, thereby reducing insertion resistance during the initial contact phase. This structure optimizes the initial alignment process of the locking pin 32 and the interface groove 11, allowing for rapid alignment without the need for precise operator adjustments to the drill bit 1 angle.

[0051] The locking pin 32 is preloaded into the snap-fit ​​engagement structure 31 via a spring mechanism, ensuring that the tapered guide head 321 actively adapts to the entrance of the interface slot 11 during insertion. The tapered guide head 321 is positioned at the end of the locking pin 32, forming a complementary guide path with the interface slot 11, effectively shortening the assembly time between the drill bit 1 and the quick connector 3. Specifically, the length and taper of the tapered guide head 321 are configured to cover the entire entrance area of ​​the interface slot 11, allowing the guide head to smoothly transition to the locking position during drill bit 1 advancement.

[0052] like Figure 4 As shown, in one embodiment, the locking pin 32 of the furniture manufacturing board drilling device of this application is machined into a conical guide head 321, for example, with a 45-degree conical angle design. Specifically, the guide head is formed by a turning process, and its conical surface is polished to enhance sliding performance. When the drill bit 1 is inserted into the quick connector 3, the conical guide head 321 automatically contacts the inlet ramp of the interface groove 11 and slides into the groove under the action of the insertion force, achieving resistance-free guidance and alignment.

[0053] The manual release lever is located on the side surface of the quick connector 3, a position optimized for easy one-handed operation. Specifically, the lever's mounting point is chosen on the outer area of ​​the quick connector 3, exposing it to the operator's direct view and reach, thus eliminating the need for additional tools or complex movements. This layout not only considers ergonomic factors but also improves the smoothness and responsiveness of the pressing action by reducing operating distance and angle.

[0054] In terms of structural composition, the manual release lever is directly connected to the locking pin 32 mechanism, forming a linkage system. This lever is typically made of a rigid material, such as metal or high-strength plastic, with its end designed as a flat or grooved surface for easy finger pressing. The connection involves the lever's fulcrum being fixed to the quick connector 3 housing, while the other end is coupled to the release mechanism of the locking pin 32 via a mechanical interface. When pressure is applied, the lever, through a pivoting motion, drives the displacement of the locking pin 32, interrupting its engagement with the drill bit 1, thereby achieving rapid unlocking. The entire assembly is compactly integrated, ensuring reliability and durability during frequent operation.

[0055] like Figure 4 As shown, in one embodiment, a manual release lever 33 is installed on the side surface of the quick connector 3 of the furniture manufacturing board drilling device of this application. For example, the lever is fixed to the housing by a hinge and connected to the spring-preloaded locking pin 32 via a linkage mechanism. Specifically, when the operator presses the lever once, the pivoting motion of the lever directly pulls the linkage, compresses the spring and retracts the locking pin 32, causing the groove of the drill bit 1 to disengage from the snap-fit ​​engagement structure, thereby realizing one-click unlocking and removal.

[0056] The clamp 4 is mounted on the base 5 via a slide rail mechanism 41, which ensures that the clamp 4 can be linearly displaced relative to the base 5. Specifically, the slide rail mechanism 41 includes a guide rail assembly fixed to the base 5 and a slider assembly slidably connected to the guide rail assembly, wherein the clamp 4 is fixedly mounted on the slider assembly. This structure allows the clamp 4 to slide freely on the base 5 in a lateral direction, defined as parallel to the working plane of the base 5 and perpendicular to the feed direction of the drill bit 1 during drilling operations.

[0057] The guide rail assembly of the slide rail mechanism 41 is typically made of hardened steel to withstand wear from repeated sliding, while the slider assembly integrates low-friction elements, such as linear bearings or ball bushings, to ensure smooth and jam-free sliding. In terms of connection, the guide rail is bolted to the side or top surface of the base 5, while the slider assembly is directly connected to the bottom of the clamp 4 via fasteners, forming a rigid yet movable connection.

[0058] The design of the slide rail mechanism 41 allows the clamp 4 to be moved laterally away from the drilling area, which is defined as the operating space directly below the drill bit 1. When the clamp 4 slides away from this area, it creates unobstructed space for changing the drill bit 1 and prevents any part of the clamp 4 from interfering with the operating path of the quick connector 3.

[0059] like Figure 1 As shown, in one embodiment, the slide rail mechanism 41 of a furniture manufacturing board drilling device of this application includes a pair of parallel guide rails, which are fixedly installed on the top edge of the base 5. The clamp 4 is slidably mounted on the guide rails by a slider assembly, for example, the slider assembly includes a ball bearing system. The user can push the clamp 4 laterally to a preset stopping position by a handle or a pneumatic drive device, thereby ensuring that the clamp 4 is completely disengaged from the drilling area when the drill bit 1 is replaced.

[0060] A rectangular access window 51 is provided on the base 5 of the furniture manufacturing board drilling device. The position of this window is precisely configured to directly align with the quick connector 3. Specifically, the access window is formed in the main structure of the base 5, and its size and shape are designed to provide sufficient operating space to ensure that the quick connector 3 is fully exposed to the external environment, thereby forming an unobstructed operating path. The installation position of the access window is determined based on the fixed connection relationship between the quick connector 3 and the base 5, that is, the central axis of the window coincides with the central axis of the quick connector 3 to achieve direct alignment. The structure of the access window is cut from the board material of the base 5, and the edges are smoothed to avoid interference or damage during operation. At the same time, its rectangular outline helps to maximize visibility and tool accessibility.

[0061] The direct alignment design of the access window allows the operator to directly access the quick connector 3 from the outside, enabling drill bit 1 replacement without removing or adjusting other components. This structure ensures that key components such as the manual release lever 33 are unobstructed, facilitating unlocking with a single press and simplifying the process. The access window is integrated with the base 5 using a direct opening design, relying on the support frame of the base 5 itself for connection. The window boundary seamlessly connects to the base 5 material to maintain structural strength and stability.

[0062] like Figure 1 and Figure 2As shown, in one embodiment, the base 5 of the furniture manufacturing board drilling device of this application includes a rectangular opening located in the front end area of ​​the base 5, directly opposite the locking pin 32 and release rod position of the quick connector 3. Specifically, the window is reserved during the casting process of the base 5 or excess material is removed by machining. The window size is slightly larger than the outline of the quick connector 3, for example, the width is 1.5 times the diameter of the quick connector 3, and the height covers its vertical range, ensuring that the operating tool can be inserted in a straight line and touch the release rod, realizing an unobstructed operating path.

[0063] Specifically, the guide post 6 is equipped with a quick-lifting mechanism 61, which is designed to quickly raise the drill bit 1, facilitating efficient access to the quick connector 3 for drill bit 1 replacement. The quick-lifting mechanism 61 includes a pneumatic spring 62, which is mounted on the guide post 6. Specifically, one end of the pneumatic spring 62 is fixedly connected to the top bracket of the guide post 6, and the other end is connected to the sliding assembly of the drive shaft 2. Under normal conditions, the pneumatic spring 62 is in a pre-compressed state, storing elastic potential energy; when activated, its extension directly drives the drill bit 1 to rise vertically, achieving the quick-lifting function. Through a one-button operation mechanism, such as a button or lever trigger, the locking device of the pneumatic spring 62 is released, instantly raising the drill bit 1 assembly to the preset replacement height. This height position ensures that the quick connector 3 is fully exposed and easy to operate, avoiding the tedious steps of manual adjustment. The entire mechanism has a compact structural connection; the pneumatic spring 62 is rigidly connected to the fixed point of the guide post 6 and the sliding assembly, ensuring a stable and non-deviation-prone lifting process.

[0064] like Figure 3 As shown, in one embodiment, the quick lifting mechanism 61 of the furniture manufacturing board drilling device of this application includes a pneumatic spring 62. For example, the upper end of the pneumatic spring 62 is fixedly installed on the upper fixed bracket of the guide column 6, and the lower end is connected to the movable support of the drive shaft 2. Specifically, when the operator presses the one-key release button, the locking pin 32 of the pneumatic spring 62 is disengaged, the spring quickly extends, and pushes the drive shaft 2 and the drill bit 1 to slide upward along the guide column 6 to the predetermined replacement height position, so that the quick connector 3 is directly exposed to the operating area.

[0065] In actual operation, when this device is used, the clamp 4 is first used to clamp and position the furniture board to ensure that the board is firmly fixed; then, the drive shaft 2 transmits rotational power to drive the drill bit 1 to rotate, and at the same time, the drill bit 1 moves vertically under the guidance of the guide post 6 to perform the drilling operation; when the drill bit 1 needs to be replaced, the operator inserts the new drill bit 1 through the one-way insertion action of the quick connector 3, and the spring-preloaded locking pin 32 automatically engages in the groove to form a rigid connection, achieving instant locking; when removing the drill bit 1, the locking state of the locking pin 32 is released by pressing the manual release lever 33 once, and the drill bit 1 is quickly removed; the base 5 supports the entire device and the drive shaft 2 is rotatably connected through the bearing to ensure the stability and accuracy of the drilling process.
