Description

Technical Field

[0001] This utility model relates to the field of wood carving machine technology, and in particular to a multi-axis wood carving machine. Background Technology

[0002] Multi-axis wood carving machines, as core CNC equipment in the woodworking industry, can efficiently complete complex processes such as carving, hollowing, and relief carving of wood thanks to their multi-spindle collaborative or independent working design. They are widely used in high-precision processing scenarios such as mahogany furniture carving and solid wood component inlay. Their core advantage lies in their ability to simultaneously process multiple identical workpieces or perform parallel processing on multiple parts of a single workpiece, significantly improving production efficiency. Simultaneously, relying on a high-precision transmission system and advanced control system, they ensure smooth and delicate carved surfaces, reducing the cost of secondary manual processing. They are a key piece of equipment in modern woodworking, replacing multiple single-axis carving machines and reducing equipment investment and space occupation.

[0003] In scenarios where multi-axis wood carving machines simultaneously process multiple workpieces, the positioning plate is a core component ensuring workpiece positioning accuracy. Because multiple spindles need to carve multiple workpieces consistently, the positioning plate must precisely confine the workpieces within a preset processing area to prevent workpiece displacement during processing, which could lead to misalignment of the carved pattern or dimensional deviations. Therefore, the adjustability and ease of disassembly / reassembly of the positioning plate directly affect the equipment's adaptability to workpieces of different specifications and the smoothness of the overall processing flow.

[0004] However, the design of the limit plates in existing multi-axis wood carving machines has significant flaws. Most limit plates are fixedly attached to the worktable, requiring the disassembly of multiple fixed components and recalibration when adjusting the spacing. This process is cumbersome and time-consuming, making it difficult to quickly adapt to the processing needs of workpieces of different widths and lengths, resulting in extremely poor flexibility. Especially when processing requirements change from simultaneous processing of multiple workpieces to processing multiple parts of a single workpiece, the entire limit plate must be removed from the worktable to free up sufficient processing space. The disassembly and subsequent reassembly not only increase manual labor but also interrupt the processing flow, leading to a significant decrease in production efficiency.

[0005] Furthermore, while some existing technologies have optimized dust protection and transmission accuracy for multi-axis wood carving machines—for example, the dust collection mechanism designed by the patented design (CN219485981U)—they have not addressed the practicality and convenience of the limit structure. The problems of cumbersome limit adjustment and inconvenient disassembly remain unresolved, resulting in insufficient adaptability of the equipment to diverse processing needs. This hinders the full realization of the high efficiency advantages of multi-axis carving, limiting the equipment's applicability and improving processing continuity. Utility Model Content

[0006] To overcome the technical defects of the existing technology, this utility model provides a multi-axis wood carving machine that can conveniently adjust the spacing of the limiting plates and conveniently store the limiting plates.

[0007] The technical solution adopted in this utility model is as follows: it includes a multi-axis wood carving machine body, a baffle, a sliding block, a limiting plate, and a positioning component; The multi-axis wood carving machine has sliding grooves on both sides of the main worktable. A square rod is fixedly installed in the sliding groove, and a first positioning screw hole is formed in a linear array at one end of the square rod. The baffle is fixedly installed at both ends of the main worktable of the multi-axis wood carving machine. The sliding block is sleeved on the outside of the square rod, and a square block is fixedly installed on the upper end of the sliding block; The limiting plate is detachably connected to the square block via a second positioning screw, and a circular groove is provided at the upper end of the limiting plate; The positioning component includes: The first positioning screw is rotatably installed in the circular groove. The first positioning screw meshes with the first positioning screw hole to realize the positioning connection between the limiting plate and the square rod. One end of the first positioning screw passes through the sliding block and extends into the first positioning screw hole. The handwheel is rotatably mounted in the circular groove, and the handwheel is fixedly connected to the first positioning screw.

[0008] Preferably, in order to facilitate the discharge of sawdust from the sliding groove, a square hole is provided at the bottom of the sliding groove.

[0009] Preferably, in order to improve the dustproof performance of the square rod, the surface of the square rod is coated with a dustproof grease layer, which is composed of a thermosetting dry film lubricant.

[0010] Preferably, in order to improve the dustproof performance of the first positioning screw hole, a dry lubricating dustproof coating is coated on the inner side of the first positioning screw hole, and the thickness of the dry lubricating dustproof coating is 5-10μm.

[0011] Preferably, in order to limit the position of the limiting plate, a square groove is provided at the lower end of the limiting plate, and one end of the square block is inserted into the square groove.

[0012] Preferably, in order to facilitate the installation of the limiting plate, the size of the square groove matches the size of the square block.

[0013] Preferably, in order to fix the limiting plate, the second positioning screw is rotatably installed at one end of the limiting plate, and the square block has a second positioning screw hole on both sides of one end. The second positioning screw meshes with the second positioning screw hole to realize the positioning connection between the limiting plate and the square block.

[0014] Preferably, in order to ensure smooth movement of the wood, both ends of the limiting plate are smooth polytetrafluoroethylene surfaces.

[0015] The beneficial effects of this utility model are: 1. The distance between the limit plate and the two sides of the worktable can be quickly adjusted by driving the first positioning screw with a handwheel to accommodate the positioning needs of multiple pieces of wood of different sizes; the limit plate is detachably connected to the square block by the second positioning screw, and the square block matches the size of the square groove, allowing for quick assembly and disassembly of the limit plate.

[0016] 2. When multiple parts of a single workpiece need to be processed simultaneously, the limiting plate can be moved to both sides without disassembling the entire limiting plate, saving time and effort and improving processing efficiency. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0025] like Figures 1-6 As shown, this embodiment provides a multi-axis wood carving machine, including a multi-axis wood carving machine body 1, a baffle 2, a sliding block 3, a limiting plate 4, and a positioning component 5.

[0026] The multi-axis wood carving machine body 1 has sliding grooves 6 on both sides of the worktable. A square rod 7 is fixedly installed in the sliding groove 6. One end of the square rod 7 has a first positioning screw hole 8 in a linear array. The inner side of the first positioning screw hole 8 is coated with a dry lubricating dustproof coating with a thickness of 5-10μm. The surface of the square rod 7 is coated with a dustproof lubricating grease layer, which is composed of a thermosetting dry film lubricant. A square hole 12 is opened at the bottom of the sliding groove 6. During the processing, when some wood chips produced by the spindle carving wood fall into the sliding groove 6, they will fall directly to the collection device below the equipment through the square hole 12 at the bottom, avoiding the accumulation of wood chips in the sliding groove 6 and affecting the movement accuracy of the sliding block 3.

[0027] The surface of the square rod 7 is coated with a dustproof lubricating grease layer with a thickness of 9μm. On the one hand, this reduces frictional loss between the sliding block 3 and the square rod 7, ensuring smooth and uninterrupted sliding adjustment. On the other hand, it forms a physical dustproof barrier, preventing fine wood chips from entering the sliding gap and extending the service life of the transmission components. Meanwhile, the dry lubricating dustproof coating applied to the inner side of the first positioning screw hole 8 does not affect the meshing accuracy between the first positioning screw 501 and the first positioning screw hole 8, and also prevents ultrafine dust from adhering to the thread gap, avoiding thread jamming or wear, and ensuring the long-term accuracy of the limit adjustment.

[0028] The baffle 2 is fixedly installed at both ends of the worktable of the main body 1 of the multi-axis wood carving machine.

[0029] The sliding block 3 is sleeved on the outside of the square rod 7, and a square block 9 is fixedly installed on the upper end of the sliding block 3.

[0030] The limiting plate 4 is detachably connected to the square block 9 via the second positioning screw 10. The upper end of the limiting plate 4 has a circular groove 11, and the lower end of the limiting plate 4 has a square groove 13. One end of the square block 9 is inserted into the square groove 13. The size of the square groove 13 matches the size of the square block 9. The second positioning screw 10 is rotatably installed on one end of the limiting plate 4. The two sides of one end of the square block 9 have second positioning screw holes 14. The second positioning screw 10 meshes with the second positioning screw holes 14 to achieve the positioning connection between the limiting plate 4 and the square block 9. Both ends of the limiting plate 4 are smooth polytetrafluoroethylene surfaces.

[0031] like Figure 4 and Figure 5 As shown, the positioning component 5 includes: The first positioning screw 501 is rotatably installed in the circular groove 11. The first positioning screw 501 meshes with the first positioning screw hole 8 to realize the positioning connection between the limiting plate 4 and the square rod 7. One end of the first positioning screw 501 passes through the sliding block 3 and extends into the first positioning screw hole 8.

[0032] Handwheel 502 is rotatably installed in the circular groove 11 and is fixedly connected to the first positioning screw 501. During use, the operator manually rotates the handwheel 502 in the circular groove 11 at the upper end of the limiting plate 4. Since the handwheel 502 is coaxially fixedly connected to the first positioning screw 501, the rotation of the handwheel 502 directly drives the first positioning screw 501 to rotate synchronously. Simultaneously, the first positioning screw 501 meshes with the first positioning screw holes 8 linearly arrayed on the square rod 7. The operator pushes the sliding block 3, causing it to drive the limiting plate 4 to move synchronously along the sliding groove 6. Adjust the spacing between the two limit plates 4 according to the width of the multiple pieces of wood to be processed; when the spacing reaches the appropriate size, stop rotating the handwheel 502. At this time, the first positioning screw 501 is tightly engaged with the first positioning screw hole 8 at the corresponding position on the square rod 7. The self-locking characteristic of the thread is used to lock and position the sliding block 3, ensuring that the spacing does not shift during the processing. Since the first positioning screw hole 8 is a linear array design, the limit spacing can be continuously adjusted to meet the processing requirements of different specifications of workpieces. A scale can also be set at one end of the square rod 7 for auxiliary positioning. Setting the scale is an existing mature technology.

[0033] When in use, the operator first aligns the square groove 13 at the lower end of the limiting plate 4 with the square block 9 at the upper end of the sliding block 3. Since the square groove 13 and the square block 9 are perfectly matched in size, they can be quickly and without deviation. This structural design can prevent the limiting plate 4 from shifting during assembly. Then, the second positioning screw 10 installed at one end of the limiting plate 4 is rotated to precisely engage with the second positioning screw holes 14 preset on both sides of the square block 9. The limiting plate 4 and the sliding block 3 are firmly fixed by the threaded locking force. The assembly process does not require complicated tools, which provides structural protection for the subsequent positioning accuracy. When the width needs to be adapted when processing multiple pieces of wood, the distance between the two limiting plates 4 can be quickly adjusted manually through the positioning component 5.

[0034] Next, multiple pieces of wood to be processed are placed parallel to each other on the worktable of the multi-axis wood carving machine body 1. Both ends of the wood are tightly fitted with the limiting plate 4, firmly confining the multiple pieces of wood within the preset processing area. The ends of the limiting plate 4 are made of smooth polytetrafluoroethylene (PTFE), whose low coefficient of friction facilitates quick placement of the wood while preventing scratches on the wood surface. Simultaneously, it ensures that the positioning reference of the multiple pieces of wood is completely uniform, providing consistency for multi-axis synchronous carving and preventing misalignment of the carved pattern and dimensional deviations due to wood offset. When multiple parts of a single workpiece need to be processed... During processing, there is no need to disassemble the limiting plate 4. The operator rotates the handwheel 502 in the opposite direction to disengage the first positioning screw 501 from the currently engaged first positioning screw hole 8, thereby releasing the locking state of the sliding block 3. Then, the sliding block 3 is pushed to move the limiting plate 4 along the square rod 7 to both sides of the worktable until the limiting plate 4 completely gives way to the processing space of the workpiece. At this time, the workpiece can be placed directly on the worktable, and processing can be started by positioning the machine with its own processing coordinates. This design eliminates the traditional process of disassembling and reassembling the limiting plate 4, greatly shortening the adjustment time and improving the continuity of processing.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this invention. Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention. Various changes and modifications may be made to this invention without departing from its spirit and scope. All such changes and modifications fall within the scope of this invention as defined by the appended claims and their equivalents.
