Description

Technical Field

[0001] This invention relates to the field of machining equipment for solid wood beams, and more particularly to a multifunctional composite machining equipment for solid wood beams. Background Technology

[0002] In fields such as construction and railways, solid wood beams are often used as core load-bearing components. Their processing quality directly affects the mechanical properties and assembly accuracy of the overall structure. Moreover, the processing requirements for solid wood beams are becoming increasingly diversified, usually requiring multiple processes such as sawing, milling, mortise and tenon processing, surface milling, and drilling.

[0003] Currently, traditional processing methods often employ a single-function, sequential operation model, using saws, milling machines, drilling machines, etc., to complete corresponding processes. Workpieces need to be repeatedly transferred and clamped between multiple machines, resulting in significant time consumption for loading, unloading, and transfer, leading to low production efficiency and making it difficult to achieve large-scale, mass production. This is especially true for large, heavy workpieces, which are particularly difficult to handle and process, and can easily cause personal injury.

[0004] Meanwhile, existing equipment often uses fixed-spaced support platforms and simple clamping structures, which cannot flexibly adjust the support points according to the length of the workpiece. When the solid wood is large, an unreasonable distribution of support points can easily cause the middle of the workpiece to be suspended, which can easily generate forced vibrations during the cutting process, reduce the stability of the processing, and affect the surface quality and the yield of finished products.

[0005] Furthermore, solid wood cutting generates a large amount of wood chips and dust. Existing processing equipment mostly uses integrated dust collection hoods or open dust collection structures. The chip removal system consumes a lot of energy to operate continuously throughout the entire area, and it is difficult to achieve precise dust collection. The chips accumulated on the workpiece surface cannot be cleaned in time, and they are easily picked up by the rotating cutting tool, scratching the machined surface and interfering with the accuracy of subsequent clamping and positioning.

[0006] Therefore, there is an urgent need for a composite processing equipment for solid wood beams that features multi-functional processing, strong vibration-proof clamping, and efficient energy-saving chip removal. Summary of the Invention

[0013] Furthermore, the main support of the worktable is equipped with a worktable guide rail and a rack, and the machine head is equipped with an X-axis slider and a drive assembly, and the X-axis slider and drive assembly slide and mesh with the worktable guide rail and rack for transmission.

[0014] The main support of the workbench and the machine head assembly are also connected by an X-axis cable chain.

[0015] Furthermore, the nose section includes a cross frame and a nose support; The cross frame is equipped with a Z-axis slider, and the head support is equipped with a head guide rail that slides with the Z-axis slider; The headstock is also equipped with a Z-axis drive assembly, which includes a servo motor and a ball screw pair; the cross frame is equipped with a nut seat; the Z-axis drive assembly and the nut seat are used to drive the headstock to move along the Z-axis direction; A Z-axis cable chain is also connected between the cross frame and the head support; The five-axis head is fixed to the bottom of the head support.

[0016] Furthermore, the cross frame is also fixed with a Z-axis balancing cylinder, the piston rod end of which is fixedly connected to the cylinder connecting bracket set on the machine head support.

[0017] Furthermore, the protective cover assembly is installed at both ends of the workbench frame structure via protective cover brackets on both sides, and the front and rear ends of the protective cover assembly are provided with notches to avoid the solid wood beams. A cover movable plate that moves along the Z-axis is slidably connected to the notches, and a brush for cleaning debris from the surface of the solid wood beams is provided at the bottom edge of the cover movable plate.

[0018] Furthermore, the machine tool assembly has several independent chip chambers arranged in an array along its length.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0036] like Figure 1 As shown, this invention discloses a multifunctional solid wood beam composite processing equipment, including a machine tool assembly 1. The machine tool assembly 1 has several support platform assemblies 2 arranged in an array along its length direction (i.e., the Y-axis direction of the equipment), and the support platform assemblies 2 collectively fix a solid wood beam 9 to be processed. A left column assembly 7 and a right column assembly 8, movable along the Y-axis direction, are installed on both sides of the machine tool assembly 1. The left column assembly 7 and the right column assembly 8 collectively mount a worktable frame structure 4. The worktable frame structure 4 mounts a machine head assembly 5, movable along the width and height directions (i.e., the X-axis and Z-axis directions of the equipment) of the machine tool assembly 1. The machine head assembly 5 is equipped with a five-axis head 10 for performing processing actions. Furthermore, a protective cover assembly 6 is fixed to the worktable frame structure 4. Figure 5 As shown, the left column assembly 7, the right column assembly 8, the worktable frame structure 4, the machine head assembly 5, and the protective cover assembly 6 together constitute the worktable for processing solid wood beams 9. The machine tool assembly 1 and the worktable are equipped with an electrical control unit assembly 3, which is electrically connected to the machine tool assembly 1 and the worktable to control the operation of the equipment.

[0037] Machine tool assembly 1 is the base of the equipment, which is fixed to the ground. For example... Figure 2 As shown, the machine tool assembly 1 is equipped with two sets of machine tool outer rails and racks 13. Each set of machine tool outer rails and racks 13 includes a linear guide rail and a rack arranged parallel to it. The two sets of machine tool outer rails and racks 13 are respectively installed on the outer end faces of the two side walls of the machine tool assembly 1, and are used to provide Y-axis guidance and meshing transmission for the left column assembly 7 and the right column assembly 8. At the same time, the machine tool assembly 1 is also equipped with two machine tool inner rails 14. The machine tool inner rails 14 are respectively installed on the inner end faces of the two side walls of the machine tool assembly 1, and are arranged parallel to the machine tool outer rails and racks 13. The machine tool inner rails 14 are used for guiding and fixing the support table assembly 2. In addition, a Y-axis chain groove 16 is fixed to one side wall of the machine tool assembly 1. The Y-axis chain groove 16 is located in the Y-axis direction of the equipment and accommodates the Y-axis drag chain 15. One end of the Y-axis drag chain is fixed in the Y-axis chain groove 16, and the other end is fixedly connected to the right column assembly 8. When the right column assembly 8 (i.e., the worktable) moves along the Y-axis, the Y-axis cable chain 16 extends and retracts accordingly, thereby guiding and protecting the cables in the Y-axis cable chain.

[0038] The machine tool assembly 1 has several independent chip chambers 11 arranged in an array along its length to receive chips generated during machining. Each chip chamber 11 has an opening at its bottom, and they all connect to a chip removal channel 12. The chip removal channel extends along the length of the machine tool assembly 1, and one end is connected to a chip removal device (such as a vacuum cleaner, not shown in the figure) to collect and discharge chips from the equipment. Figure 3 The chip chamber 11 shown has a hinged opening / closing plate 18 at its opening. A closing rod 17 is mounted on the end wall of the chip chamber 11, with its movable end connected to the closing plate 18. When the closing rod 17 extends or retracts, it rotates the closing plate 18, thus controlling the opening and closing of the chip chamber. When the worktable moves to the processing position of a specific chip chamber 11, only the closing plate 18 corresponding to that position can be opened, while the closing plates 18 of the other chip chambers remain closed. This achieves targeted chip removal and reduces equipment energy consumption.

[0039] The support platform assemblies 2 are used for positioning and supporting the solid wood crossbeams 9. They are movably mounted on the machine tool assembly 1 via the machine tool inner rail 14, and each support platform assembly 2 is independent of the others. The spacing between each support platform assembly 2 can be adjusted to accommodate solid wood crossbeams 9 of different lengths. Figure 4The shown support platform assembly 2 includes a support platform frame 21, and two sets of sliders and clamps 22 are fixed to the bottom of the support platform frame 21. The sliders and clamps 22 are divided into two parts: sliders and clamps. The sliders slide in engagement with the machine tool inner rail 14, allowing the support platform assembly 2 to move along the Y-axis. The clamps are pneumatically or hydraulically driven locking devices. When the support platform assembly 2 moves to a predetermined position, the clamps activate to lock the support platform assembly 2 onto the machine tool inner rail 14, preventing it from moving during further processing.

[0040] The support platform frame 21 is a box-type structure with an open front end. A slide cylinder assembly 23 is installed inside, and a reference clamping assembly 25 is fixed to the rear end wall. Specifically, the reference clamping assembly 25 is located on one side of the rear end wall and includes a reference cylinder and a connected reference clamping plate. The reference cylinder can drive the reference clamping plate to move up and down to adapt to solid wood beams 9 of different heights. The movable end of the slide cylinder assembly 23 moves along the length direction of the support platform assembly 2 (i.e., the X-axis direction of the equipment). The movable end protrudes from the front opening of the support platform frame 21, and a clamping column 24 is vertically fixed to the movable end along the height direction of the support platform assembly 2 (i.e., the Z-axis direction of the equipment). The clamping column 24 is a column with an arc-shaped cross-section, and its cross-section is the clamping surface of the clamping column 24. The clamping surface of the clamping column 24 and the clamping surface of the reference clamping plate are parallel and opposite, and both clamping surfaces are fitted with clamping pads. In addition, a horizontal plate-shaped support plate 26 is fixed to the top surface of the support platform frame 21, which is used to directly support the solid wood beam 9, and the support plate 26 is provided with anti-slip texture to enhance the friction with the solid wood beam 9.

[0041] When the solid wood beam 9 is placed on the support plate 26, the movable end of the slide cylinder assembly 23 drives the clamping column 24 to move towards the reference clamping plate until the clamping column 24 and the reference clamping plate clamp each other from both sides of the solid wood beam 9, thereby achieving precise positioning and firm clamping of the solid wood beam 9 in the horizontal direction.

[0042] like Figure 1As shown, this invention discloses a multifunctional solid wood beam composite processing equipment, including a machine tool assembly 1. The machine tool assembly 1 has several support platform assemblies 2 arranged in an array along its length direction (i.e., the Y-axis direction of the equipment), and the support platform assemblies 2 collectively fix a solid wood beam 9 to be processed. Left column assemblies 7 and right column assemblies 8, movable along the Y-axis direction, are installed on both sides of the machine tool assembly 1. A workbench frame structure 4 is jointly installed on the left column assemblies 7 and right column assemblies 8. The workbench frame structure 4 is connected to a protective cover assembly 6 and a machine head assembly 5 movable along the width and height directions (i.e., the X-axis and Z-axis directions of the equipment) of the machine tool assembly 1. The left column assemblies 7, right column assemblies 8, workbench frame structure 4, machine head assembly 5, and protective cover assembly 6 together constitute a workbench for processing the solid wood beam 9. An electrical control unit 3 is installed outside the machine tool assembly 1 and the worktable, and the electrical control unit 3 is electrically connected to the machine tool assembly 1 and the worktable to control the operation of the equipment.

[0043] The left column of the workbench is equipped with 7 and the right column is equipped with 8, as shown. Figure 8 As shown, the left column assembly 7 and the right column assembly 8 are respectively provided with mirrored left column brackets 70 and right column brackets 80. Both the left column bracket 70 and the right column bracket 80 are provided with vertical bearing plates, and each bearing plate is provided with a Y-axis slider and a drive assembly 30.

[0044] like Figure 8 As shown, the left column assembly 7 and right column assembly 8 of the worktable are mirror images of each other, each equipped with a left column support 70 and a right column support 80, respectively. Both the left and right column supports 70 and 80 have a Y-axis slider and a drive assembly 30 at their bottom ends. The Y-axis slider and drive assembly 30 include a slider, a servo motor, a reducer, and a drive gear. The slider slides along the linear guide of the machine tool's outer rail and rack 13; the drive gear meshes with the rack of the machine tool's outer rail and rack 13. Driven by the servo motor, the drive gear rotates along the rack, thereby driving the left and right column assemblies to move along the Y-axis. Both the left and right column supports 70 and 80 are also equipped with photoelectric sensors 36, which can detect the presence, position, and distance of the solid wood beam 9, ensuring the processing accuracy of the equipment and preventing problems such as empty cutting.

[0045] It should be noted that the left column assembly 7 has no additional machining accessories, while the right column assembly 8 integrates a tool magazine and saw blade magazine assembly. The right column bracket 80 is fixed with a saw blade bracket 33 and a tool magazine bracket 34. The saw blade bracket 33 holds the saw blade 31; the tool magazine bracket 34 is equipped with a cutter head 32, which is a disc-type tool magazine with several tool clamping positions on its circumference for holding milling tools of different specifications. The five-axis head 10 of the worktable is equipped with an automatic tool changer interface, which, in conjunction with the tool magazine and saw blade magazine assembly, enables the replacement and loading / unloading of tools and saw blades. The right column bracket 80 is also fixed with a Y-axis cable chain connector 35, which is used for connecting the Y-axis cable chain 15.

[0046] The workbench frame structure 4, the left column assembly 7, and the right column assembly 8 are fixed together to form the gantry-type support structure of the workbench. For example... Figure 7 The workbench frame structure 4 shown includes a main workbench support 41, which is a beam structure. Its bottom end is fixedly connected to the left column support 70 and the right column support 80 by bolts. The main workbench support 41 is fixed with workbench guide rails and a rack 46. The workbench guide rails and rack 46 include two linear guide rails located on the front wall of the main workbench support 4 and a rack located on the top wall of the main workbench support 4. The rack and the linear guide rails are arranged in parallel. The workbench guide rails and rack 46 are used to provide X-axis guidance and meshing transmission for the machine head assembly 5.

[0047] The workbench is also equipped with a pressure roller assembly, which includes a front roller assembly 45 and its connected front pressure roller 43, and a rear roller assembly 48 and its connected rear pressure roller 44. The front roller assembly 45 is mounted on a pressure roller bracket 42, which is fixed to the front wall of the main support 4 of the workbench. The rear roller assembly 48 is mounted on the inner walls of the left and right column supports via a fixing bracket. The front roller assembly 45 and the rear roller assembly 48 have the same structure, both including a vertically arranged guide rod and a lifting cylinder. The movable end of the lifting cylinder and the end of the guide rod are connected to a pressure roller transition plate. The front pressure roller 43 and the rear pressure roller 44 are respectively hinged to the two pressure roller transition plates of their respective components. The lifting cylinder drives the front and rear pressure rollers to rise and fall to fit against the upper surface of the solid wood beam 9, providing a stable vertical clamping force, thereby suppressing the vertical vibration of the solid wood beam during processing and ensuring the processing accuracy and quality of the equipment.

[0048] The head unit 5 is the equipment's execution unit, such as... Figure 9As shown, it includes a cross frame 51 and a head support 56. The rear end face of the cross frame 51 is provided with an X-axis slider and a drive assembly 52. ​​Through the sliding engagement and drive meshing of the X-axis slider and drive assembly 52 with the worktable guide rail and rack 46, the head assembly 5 moves along the X-axis. Head guide rails 58 are installed on the left and right end walls of the head support 56 along the Z-axis. Z-axis sliders 53, which mate with the head guide rails 58, are fixed to the inner surfaces of the left and right end walls of the cross frame 51. The Z-axis sliders 53 and the head guide rails 58 are used for Z-axis guidance of the head support 56. Simultaneously, a Z-axis drive assembly is fixed to the top of the rear end wall of the head support 56. The Z-axis drive assembly includes a servo motor and a ball screw pair. A nut seat for the ball screw is provided on the front end face of the rear end wall of the cross frame 51. Therefore, driven by the servo motor, the ball screw screws in and out of the nut seat, thereby realizing the movement of the head support 56 in the Z-axis direction.

[0049] The five-axis head 10 is fixed to the end (bottom) of the headstock bracket 56. It is a five-axis linkage machining head with two rotary axes, an A-axis (rotating around the X-axis) and a C-axis (rotating around the Z-axis), and three linear axes, X, Y, and Z, enabling five-axis linkage machining. The five-axis head 10 is equipped with an electric spindle, and a tool clamping mechanism is installed at the end of the electric spindle for clamping milling tools. Simultaneously, an automatic tool changer is provided on the side of the five-axis head 10. The five-axis head 10 cooperates with the cutter head 32 to achieve automatic tool loading, unloading, and replacement. The five-axis head 10 can perform multi-angle milling on the upper surface and sides of the solid wood beam 9, and can also use a saw blade 31 to complete end face cutting.

[0050] In addition, a Z-axis balancing cylinder is fixed to the cross frame 51. The piston rod end of the Z-axis balancing cylinder is fixedly connected to the cylinder connecting bracket 59 provided on the head support 56. The Z-axis balancing cylinder 54 is a cylinder with a locking function, and compressed air at a constant pressure is introduced into it. The thrust direction of the Z-axis balancing cylinder 54 is opposite to the direction of gravity, which is used to counteract the self-weight of the five-axis head 10 and the head support 56, reduce the load on the Z-axis drive assembly 57, and thus improve the dynamic response speed and positioning accuracy of the Z-axis movement. A worktable electrical box 55 is also provided at the top of the cross frame 51 for controlling the movement of the five-axis head 10 along each axis direction. One end of the workbench electrical box 55 is connected to an X-axis cable chain 37, which is connected to the X-axis cable chain connecting frame 47 of the workbench frame structure 4; the other end of the workbench electrical box 55 is connected to a Z-axis cable chain 38, which is connected to the Z-axis cable chain connecting frame 39 of the machine head assembly 5. The X-axis cable chain 37 and the Z-axis cable chain 38, like the Y-axis cable chain 15, are used to guide and protect the cables therein.

[0051] like Figure 6The protective cover assembly 6 shown is mounted on both ends of the workbench frame structure 4 via protective cover brackets 61 on both sides, thereby isolating the processing area from the external environment and protecting operators from flying debris and rotating tools. The front and rear ends of the protective cover assembly 6 are provided with notches to avoid the solid wood crossbeams, and sliding cover movable plates 62 (moving along the Z-axis) are connected to these notches. The cover movable plates 62 are designed to accommodate solid wood crossbeams 9 of different heights and facilitate workpiece loading and unloading and equipment maintenance. Furthermore, a brush 63 is installed on the bottom edge of the cover movable plate 62, with bristles extending downwards. When the workbench moves along the machine tool assembly 1, the bristles of the brush 63 contact the upper surface of the solid wood crossbeam 9, sweeping the accumulated debris onto the surface into the debris chamber 11 of the machine tool assembly 1, preventing the dispersion of wood dust.

[0052] The overall working process and linkage logic of this invention are described below: Workpiece loading and positioning. Adjust the positions of each support platform assembly along the Y-axis according to the length of the solid wood beam to be processed, and lock them in place using clamps. Hoist the solid wood beam onto the support plate, ensuring one side of the beam is flush against the reference clamping assembly. Activate the slide cylinder assembly; the clamping column extends and presses the solid wood beam against the other side, completing the horizontal positioning and clamping of the workpiece.

[0053] Workpiece clamping. Control the cylinders of the front and rear roller assemblies to move the front and rear pressure rollers downwards, pressing them against the top of the solid wood crossbeam, applying a vertical clamping force to prevent the workpiece from vibrating up and down during processing.

[0054] Machining Preparation. Start the CNC system of the electrical control unit assembly and import the machining program. According to the instructions of the machining program, the system controls the left and right column assemblies to move synchronously along the Y-axis, moving the head assembly to the machining start position. At the same time, the control system controls the opening and closing plates of the corresponding chip chambers to open via the cavity opening and closing levers according to the X-axis position of the head assembly, activating the chip removal device.

[0055] Composite machining. Following the instructions of the CNC program, the machine head moves along the X and Z axes, while the A and C axes of the five-axis head oscillate according to the program, performing multi-angle milling on the upper surface and sides of the solid wood beam. Additionally, the saw blade cuts the end faces of the solid wood beam. Throughout the entire machining process, the front and rear pressure rollers maintain constant pressure on the workpiece, and the chip removal device operates continuously.

[0056] Unload the workpiece. After processing, turn off the chip removal device, control the front and rear pressure rollers to lift, and the slide cylinder assembly to retract, causing the clamping column to release the solid wood beam, and lift the processed solid wood beam away from the equipment.

[0057] In summary, this invention utilizes a multi-partitioned chip removal structure within the machine tool assembly, along with matching cavity opening and closing rods and plates, to create a zoned chip removal system. Combined with the sealing brushes in the protective cover assembly, this achieves targeted dust collection, resulting in highly efficient and energy-saving chip removal. Multiple sets of sliding and locking support platforms along the machine tool guideways allow for flexible spacing adjustment based on the length of the solid wood beam. These, along with the reference clamping assembly and the lateral positioning of the clamping columns driven by the slide cylinder, and further reinforced by the vertical pressing of the front and rear pressure rollers on the worktable frame structure, form a comprehensive force-bearing system that effectively suppresses vibration during the cutting of long solid wood beams. This invention significantly improves workpiece machining accuracy and surface quality. The gantry-type worktable, combined with a five-axis head unit, enables integrated composite operations such as sawing, milling, and drilling. Automatic and rapid tool changing is achieved via the saw blade and cutter head mounted on the right column, eliminating the need for multiple workpiece transfer steps and greatly improving production efficiency. The support table unit can be flexibly adjusted along the machine tool's internal rails to accommodate solid wood beams of different lengths and specifications. Combined with the multi-angle machining capabilities of the five-axis head, the equipment possesses exceptional machining flexibility. The protective cover unit isolates the machining area from the operators, maximizing personal safety. This invention effectively solves problems such as vibration, chip removal, and reduced efficiency due to inter-process transfer in solid wood beam machining, making it suitable for mass production of solid wood beams of various specifications in construction, railway, and other industries.
