Description

Technical Field

[0001] This invention relates to the field of intelligent manufacturing equipment technology, and more specifically, to a highly flexible CNC six-sided drilling device. Background Technology

[0002] In the intelligent manufacturing equipment industry, panel furniture, with its advantages of personalized design and high space utilization, is experiencing a continuous rise in market demand. This has also placed higher demands on the performance of core processing equipment—the CNC six-sided drill. Currently, the CNC six-sided drill has gradually expanded from its traditional single function of drilling and grooving to complex processes such as panel cutting and laminar flow processing, becoming a key piece of equipment on panel furniture production lines.

[0003] However, existing CNC six-sided drilling machines still have many technical pain points that need to be addressed in practical applications: For multi-sided processing requirements such as four-sided grooving and six-sided drilling of panels, traditional equipment needs to switch grippers and adjust clamping positions multiple times. The frequent clamping and positioning process is prone to cumulative errors, resulting in key processing indicators such as hole accuracy and groove parallelism failing to meet standards; Panel furniture panels are prone to warping and surface unevenness during production and storage due to changes in environmental humidity and uneven stress. Traditional rigid processing structures cannot adapt to such shape deviations, which in turn affects the drilling accuracy of horizontal and vertical holes and may even cause chipping of the panel edges; Fourth, when facing different hole diameters and different processing requirements, traditional equipment needs to stop for tool replacement, which is cumbersome and interrupts the processing flow, further restricting the improvement of production efficiency and making it difficult to meet the flexible production needs of small batches and multiple batches in the customized furniture industry. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a highly flexible CNC six-sided drilling device, which aims to solve the problems mentioned in the background art.

[0005] The present invention provides the following technical solution: a highly flexible CNC six-sided drilling device, including a support frame, on which processing components are mounted; The processing assembly includes an adjustable center seat located in the middle of the support, and a positioning assembly for multi-faceted adjustment of the workpiece is provided on the top of the center seat. The center seat has rotating plates on both sides, and each rotating plate has several support plates on its outer side. Servo motors are slidably connected to the support plates, and each servo motor has a processing head at its output end. The position of each support plate and processing head is adjusted by rotating the rotating plates, and the servo motors slide on the support plates to make the processing head flexibly abut against the workpiece for processing. Several deflection rods are rotatably connected to the plate, and the vertical cross-section of the deflection rods is set to L-shape. The vertical section of the deflection rod extends to one end of the support plate, and the horizontal section of the deflection rod is provided with a pulley. During the rotation of the support plate, the deflection rods are indirectly driven to deflect, so that the deflection rods drive the servo motor to adjust the position on the support plate accordingly.

[0006] Optionally, in one possible implementation, the processing assembly further includes a carriage disposed at one end of the pallet, the carriage being slidably connected to the pallet, and the vertical section of the deflection rod abutting against the carriage and being slidably connected to the carriage, so that when the deflection rod deflects, it drives the carriage to slide on the pallet. A plurality of push rods are fixedly disposed on the carriage, and a return spring is respectively sleeved on the outer side of each push rod. One end of the push rod extends to the servo motor, so that when the carriage is displaced, it drives the push rod to displace, thereby driving the servo motor to move laterally on the pallet and causing the return spring to be stressed. When the elasticity of the return spring itself causes the carriage to lose the push force of the deflection rod, the servo motor and the processing head reset. An eccentric disk is movably connected at the axis of the rotating plate, the eccentric disk being eccentrically disposed with the rotating plate and fixed on the bracket. The eccentric disk abuts against the pulley, so that when the rotating plate and the deflection rod rotate, the pulley slides on the eccentric disk, causing the deflection rod to deflect through the inclined surface of the eccentric disk and drive the carriage to move laterally on the pallet. Optionally, in one possible implementation, the positioning assembly includes a first hinge seat disposed on the top of the center seat, a second hinge seat with an adjustable angle hinged to the first hinge seat, an adjustable hinge platform hinged to the top of the second hinge seat, a processing table rotatably connected to the top of the hinge platform, a plurality of clamping rods for positioning the workpiece disposed on the processing table, and locking knobs for positioning the second hinge seat and the hinge platform respectively rotatably connected to the first hinge seat and the second hinge seat, for locking after adjusting the angle of the second hinge seat and the hinge platform by rotating the locking knobs on the first hinge seat and the second hinge seat respectively. Optionally, in one possible implementation, the processing head includes a protective cover disposed at the output end of a servo motor. A first drive motor is disposed inside the protective cover. A locking sleeve is disposed at one end of the first drive motor. A drill bit for drilling is disposed at the bottom of the locking sleeve. The locking sleeve is rotatably connected to the protective cover. The servo motor drives the protective cover to rotate, thereby adjusting the drilling angle of the drill bit. Bevel gears are respectively disposed at the output end of the first drive motor and on the outer side of the drill bit, and the two bevel gears mesh with each other. The rotation of the bevel gear at the output end of the first drive motor drives the bevel gear on the locking sleeve to rotate, thereby driving the drill bit to rotate for drilling. The center seat is slidably connected to the bracket via an electric slide rail. A screw drive module for driving the positioning component to move laterally is disposed on the center seat. The electric slide rail drives the center seat to move on the bracket, and the screw drive module drives the positioning component to move on the center seat, for lateral and longitudinal adjustment of the positioning component. The rotating plate is mounted on the bracket via a bearing seat, and a second drive motor for driving the rotating plate to rotate is disposed at one end of the bearing seat. The technical effects and advantages of this invention are as follows: 1. The positioning component of this invention, through a multi-stage hinge structure consisting of a first hinge seat, a second hinge seat, and a hinge table, combined with the rotation function of the processing table, enables omnidirectional adjustment of the workpiece in the transverse, longitudinal, multi-angle, and circumferential directions. With the stable clamping of the clamping rod and the precise locking of the locking knob, it not only adapts to plates of different sizes and shapes but also compensates for shape deviations caused by plate warping through angle compensation, ensuring that the processed surface is always in a flat processing posture. This design reduces the cumulative error caused by multiple clamping operations in traditional equipment, laying the foundation for subsequent high-precision machining. 2. This invention is based on a collaborative structure of a rotating plate, a deflecting rod, an eccentric disk, and a return spring. During the rotation of the rotating plate to switch the machining surface, the pulley slides along the inclined surface of the eccentric disk, indirectly driving the deflecting rod to push the servo motor to achieve progressive feed. This mechanical linkage design, which synchronizes position switching and feed action, avoids the time gaps of step-by-step operation in traditional equipment, thus improving processing efficiency. On the other hand, the buffering effect of the return spring allows the machining head to form a flexible contact with the workpiece, which can adaptively compensate for the size deviation of the plate, avoiding excessive or insufficient drilling depth, and also avoid problems such as plate chipping and drill breakage caused by rigid contact. While ensuring processing accuracy, it extends the service life of the core components of the equipment. 3. The processing head of this invention is driven by a servo motor to rotate the protective cover. With the help of the bevel gear transmission structure, the drilling angle can be flexibly adjusted without changing the tool, which can adapt to the processing needs of holes in different directions. This integrated design complements the above-mentioned flexible positioning and linkage feed structure, so that the equipment can complete complex processes such as multi-sided drilling and grooving of plates without stopping the machine to adjust the clamping position or change the tool. This greatly shortens the processing cycle, reduces the intensity of manual operation, and is suitable for flexible production scenarios. Attached Figure Description

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0017] Example 1 This embodiment discloses a highly flexible CNC six-sided drilling equipment, which is mainly used for six-sided drilling, grooving and other processing processes of panel furniture. It can effectively solve the problems of traditional six-sided drilling, such as the need to switch grippers multiple times, large cumulative error in clamping and positioning, insufficient drilling accuracy due to panel warping, low processing efficiency and inconvenience in changing tools.

[0018] Specifically, such as Figure 1 , Figure 2 As shown, the highly flexible CNC six-sided drilling equipment includes a support 1, on which a processing component is mounted. The processing component is the core structure for realizing flexible drilling of multiple sides of the plate. Its specific composition and connection relationship are as follows: The processing component includes a central seat 2 located in the middle of the support 1. The central seat 2 is slidably connected to the support 1 via an electric slide rail, which allows for fine adjustment of the longitudinal displacement of the central seat 2 along the support 1. At the same time, a lead screw drive module 23 is provided on the central seat 2. The lead screw drive module 23 is connected to the positioning component and is used to drive the positioning component to move laterally on the central seat 2. Through the cooperation of the electric slide rail and the lead screw drive module 23, the positioning component can be flexibly adjusted laterally and longitudinally to meet the processing and positioning requirements of different positions of the plate.

[0019] like Figure 6 As shown, the positioning assembly is located on the top of the center seat 2 and includes a first hinge seat 12, a second hinge seat 13, a hinge table 14, a processing table 15, a clamping rod 16, and a locking knob 17.

[0020] The first hinge seat 12 is fixed on the lead screw drive module 23. The second hinge seat 13 is hinged to the first hinge seat 12 and can be adjusted around the first hinge seat 12. The hinge table 14 is hinged to the top of the second hinge seat 13 and can be adjusted left and right around the second hinge seat 13. The processing table 15 is rotatably connected to the top of the hinge table 14 and can rotate 360°. Several clamping rods 16 are evenly arranged on the processing table 15. The clamping rods 16 are connected to the processing table 15 by thread. Rotating the clamping rods 16 can clamp and position the plate, ensuring that the plate is stable and does not shift during processing.

[0021] Locking knobs 17 are rotatably connected to the first hinge seat 12 and the second hinge seat 13, respectively. After the second hinge seat 13 and the hinge table 14 are adjusted to the target angle, rotating the corresponding locking knob 17 can lock them in place, preventing angle deviation from affecting machining accuracy during processing. Through multi-dimensional adjustment of the positioning components, it can adapt to the warping of the sheet metal. Angle compensation ensures that the machined surface of the sheet metal remains flat, and different angle machining requirements can be achieved without repeated clamping. Furthermore, the locking knob 17 is a set screw with a tapered end, which is screwed into the threaded holes of the first hinge seat 12 and the second hinge seat 13 respectively. Its tapered end abuts against the corresponding hinge shaft, and the angle position is locked by friction to prevent loosening caused by processing vibration.

[0022] Example 2 Based on Example 1, this embodiment, for example Figure 1 , Figure 3 As shown, rotating plates 3 are respectively arranged on the left and right sides of the center seat 2. The rotating plates 3 are mounted on the bracket 1 through bearing seats. A second drive motor 24 is fixedly installed at one end of the bearing seat. The output end of the second drive motor 24 is connected to the rotating plate 3 and is used to drive the rotating plate 3 to rotate around the axis of the bearing seat. Several support plates 4 are evenly arranged circumferentially on the outer side of each rotating plate 3. The support plates 4 are fixedly connected to the rotating plate 3 and rotate synchronously with the rotating plate 3. A servo motor 5 is slidably connected to each support plate 4 through a slide rail. The sliding direction of the servo motor 5 is consistent with the length direction of the support plate 4. A processing head is provided at the output end of the servo motor 5. The spatial position of the support plate 4 and the processing head can be adjusted by rotating the rotating plate 3. Combined with the sliding of the servo motor 5 on the support plate 4, the processing head can flexibly abut against different processing surfaces of the plate to realize multi-face drilling.

[0023] like Figure 3 , Figure 5 As shown, a deflection rod 6 is rotatably connected to the rotating plate 3 via a rotating shaft. The vertical cross-section of the deflection rod 6 is L-shaped, with its vertical section extending to one end of the support plate 4 and its horizontal section facing the axis of the rotating plate 3. A pulley 10 is rotatably connected to the end of the horizontal section of the deflection rod 6. A slide 7 is slidably connected to one end of the support plate 4 near the vertical section of the deflection rod 6. The sliding direction of the slide 7 is consistent with the sliding direction of the servo motor 5. The vertical section of the deflection rod 6 abuts against the side of the slide 7 and is slidably connected to the side of the slide 7. When the deflection rod 6 deflects around the rotating shaft, its vertical section can push the slide 7 to slide on the support plate 4. Several push rods 8 are fixedly installed on the side of the slide 7 facing the servo motor 5. The push rods 8 are fixedly connected to the housing of the servo motor 5. A return spring 9 is sleeved on the outside of the push rod 8. One end of the return spring 9 abuts against the push rod 8, and the other end abuts against the limiting protrusion of the support plate 4. When the slide 7 slides towards the servo motor 5, the push rod 8 pushes the servo motor 5 to move synchronously, and at the same time, the return spring 9 is compressed and stores force. When the slide 7 loses its thrust, the elastic restoring force of the return spring 9 drives the slide 7, the push rod 8 and the servo motor 5 to return to their original positions.

[0024] like Figure 3As shown, an eccentric disk 11 is movably connected to the axis of the rotating plate 3. The eccentric disk 11 is eccentrically positioned to the rotating plate 3 and is fixed to the bracket 1 by bolts. The outer circumferential surface of the eccentric disk 11 is an inclined cam surface and abuts against the pulley 10 on the deflection rod 6. When the second drive motor 24 drives the rotating plate 3 to rotate, the rotating plate 3 drives the support plate 4, the deflection rod 6, and the pulley 10 to rotate synchronously around the axis of the rotating plate 3. The pulley 10 slides on the cam surface of the eccentric disk 11. As the rotation angle changes, the cam surface of the eccentric disk 11 pushes the pulley 10 to drive the deflection rod 6 to deflect around the axis, thereby driving the carriage 7 to move laterally on the support plate 4, realizing the feed adjustment of the servo motor 5 and the processing head. Flexible feed is achieved through the linkage of the mechanical structure, avoiding hard contact that could cause damage to the workpiece or a decrease in processing accuracy. Furthermore, the outer circumferential surface of the eccentric disk 11 has a continuous and smooth profile. Its profile curve can be designed according to the required feed displacement function, so that when the rotating plate 3 rotates, the pulley 10 rolls along the cam profile, driving the deflection rod 6 to generate a continuous and progressive deflection displacement corresponding to the rotation angle, thereby driving the servo motor 5 through the carriage 7 and the push rod 8 to achieve flexible feeding.

[0025] Example 3 Based on Example 2, this embodiment, for example Figure 4 , Figure 7 As shown, the processing head includes a protective cover 18, a first drive motor 19, a locking sleeve 20, a drill bit 21, and a bevel gear 22.

[0026] The protective cover 18 is fixedly mounted on the output end of the servo motor 5, rotating and shifting synchronously with the servo motor 5. The first drive motor 19 is fixed inside the protective cover 18 by bolts, and the output end of the first drive motor 19 is fixedly connected to one of the bevel gears 22. The locking sleeve 20 is rotatably connected to the protective cover 18 through a bearing. The bottom of the locking sleeve 20 is provided with a clamping hole for mounting the drill bit 21. The drill bit 21 is fixed to the locking sleeve 20 by locking bolts. Different specifications of drill bits 21 can be replaced according to processing requirements without disassembling the entire processing head, making replacement convenient. The other bevel gear 22 is fixedly sleeved on the outside of the locking sleeve 20 and meshes with the bevel gear 22 at the output end of the first drive motor 19. When it is necessary to adjust the drilling angle, the servo motor 5 drives the protective cover 18 to rotate, driving the drill bit 21 to rotate synchronously to the target angle. When drilling, the first drive motor 19 starts, and through the two meshing bevel gears 22, it drives the locking sleeve 20 and the drill bit 21 to rotate at high speed to achieve drilling processing.

[0027] The specific working principle is as follows: Panel positioning: Place the panel to be processed on the processing table 15, and rotate the clamping rod 16 to clamp and fix the panel; according to the processing requirements of the panel, adjust the longitudinal position of the center seat 2 through the electric slide rail, and adjust the lateral position of the positioning component through the lead screw transmission module 23; if the panel is warped or requires processing at a specific angle, adjust the vertical angle of the second hinge seat 13 and the horizontal angle of the hinge table 14, rotate the processing table 15 to adjust the orientation of the panel, and after adjustment, rotate the locking knob 17 to lock and position, ensuring that the processing surface of the panel is flat and in the target processing position.

[0028] Adjusting the position of the machining head: Start the second drive motor 24 to drive the rotating plate 3 to rotate. The rotating plate 3 drives the support plate 4, the servo motor 5 and the machining head to rotate to the corresponding position of the surface to be machined on the plate. During the rotation of the rotating plate 3, the pulley 10 slides on the cam surface of the eccentric disk 11, pushing the deflection rod 6 to deflect. Then, through the slide 7 and the push rod 8, the servo motor 5 is pushed to feed towards the plate, so that the drill bit 21 flexibly abuts against the plate near the machining surface. At the same time, the return spring 9 is compressed.

[0029] Drilling Angle and Processing: According to the drilling requirements, the servo motor 5 is started, driving the protective cover 18 to rotate, which in turn drives the drill bit 21 to adjust to the target drilling angle; the first drive motor 19 is started, which drives the drill bit 21 to rotate through the bevel gear 22. At the same time, under the continuous push of the deflection rod 6, the servo motor 5 slowly feeds to realize the drilling process; when the surface is processed, the second drive motor 24 continues to drive the rotating plate 3 to rotate, and the pulley 10 slides on the eccentric disk 11 to the low position of the cam surface. The return spring 9 drives the servo motor 5 and the processing head to return to the original position. At the same time, the positioning component can adjust the plate angle or the rotating plate 3 can drive other processing heads to rotate to the corresponding position to drill the next surface without having to repeatedly clamp the plate.

[0030] Example 4 In the above steps, the feed of the machining head of a traditional six-sided drill is mostly rigidly driven, such as direct cylinder push or lead screw hard connection transmission. If the workpiece is warped, has an uneven surface, or has a slight deviation between the machining surface and the feed direction, it is very easy for the machining head to make hard contact with the workpiece. This can cause scratches or chipping on the workpiece surface, or even breakage of the drill bit 21 or overload damage to the servo motor 5.

[0031] Conversely, when the pulley 10 slides along the inclined cam surface of the eccentric disk 11, the driving force is transmitted step by step through the deflection rod 6, the slide 7, and the push rod 8, and the return spring 9 always provides a reverse buffering force. The traction force generated by the corresponding cooperation between the pulley 10 and the eccentric disk 11, combined with the buffering effect of the return spring 9, makes the displacement of the servo motor 5 progressively feed: when the processing head approaches the workpiece, the feed force increases slowly with the eccentricity of the eccentric disk 11. If it encounters a protruding or warped part of the plate, the return spring 9 can absorb the impact force through a small compression, realizing the flexible contact between the processing head and the workpiece, fundamentally avoiding damage to the equipment and workpiece caused by hard contact; Meanwhile, the cam surface of the eccentric disk 11 is a continuous smooth curved surface, and the sliding trajectory of the pulley 10 is a continuous curve. The corresponding deflection angle of the deflection rod 6 and the displacement of the servo motor 5 are both continuously adjustable. When there is a deviation in the plate size, the return spring 9 can adaptively compensate for this deviation through elastic deformation: when the plate size is too large, after the machining head is fed to the preset position, the return spring 9 is further compressed to avoid overfeeding; when the plate size is too small, the return spring 9 releases its elastic potential energy, pushing the machining head to continue approaching the workpiece to ensure the drilling depth meets the standard. This adaptive adjustment capability allows the equipment to be compatible with a certain range of plate size deviations, eliminating the need for frequent adjustments to equipment parameters and ensuring consistent processing accuracy across different batches of plates. Furthermore, in this design, the deflection rod 6 is fixedly connected to the rotating plate 3 and rotates synchronously with the rotating plate 3. The rotation of the rotating plate 3 is both the process of the machining head switching machining surfaces, such as adjusting the position from the front to the side or top of the workpiece, and the process of the pulley 10 sliding along the eccentric disk 11 and driving the machining head to feed closer. The two actions are completed synchronously through mechanical linkage, without the need for additional independent feed control commands, which greatly shortens the connection time for switching machining surfaces, and is especially suitable for multi-face continuous machining scenarios of workpieces.

[0032] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
