[0002] With the development of CNC technology and intelligent manufacturing, five-axis machining centers are widely used in the aerospace, precision manufacturing, and woodworking industries. Especially in the woodworking field, the machining of complex structural parts is becoming increasingly refined and diversified, placing higher demands on the structural flexibility and precision of machining equipment.

[0003] 1. Most existing woodworking five-axis linkage machining centers adopt a fixed structure, which has the following problems:

[0004] 2. The workbench is a fixed structure, which cannot be adapted to wooden workpieces of different shapes and sizes. The clamping method is limited, which restricts processing efficiency.

[0005] 3. The spindle has a simple structure and poor functional expandability, making it difficult to meet the processing needs of multiple processes and different materials;

[0006] 4. Workpieces often need to be flipped and reclamped multiple times during processing, which can easily cause positioning errors and affect processing accuracy;

[0007] 5. Lacks a flexible and replaceable modular structure, making it impossible to quickly switch processing modes according to specific working conditions;

[0008] 6. The current system is not adaptable enough to heavy-duty processing or complex curved surface forming, which affects the equipment's versatility and overall efficiency.

[0009] Therefore, there is an urgent need to provide a woodworking horizontal five-axis linkage machining center with flexible structure, high modularity, and strong adaptability to solve the above problems. Utility Model Content

[0010] The purpose of this utility model is to provide a woodworking horizontal five-axis linkage machining center, which overcomes the problems of fixed structure, limited spindle function, inconvenient clamping and insufficient flexibility of existing woodworking five-axis linkage machining centers.

[0011] This utility model is achieved using the following technical solution: a woodworking horizontal five-axis linkage machining center, characterized in that it includes a worktable base, an X-axis feed mechanism, an X-axis slide plate, a worktable, a column, a Z-axis slide plate, a Y-axis feed mechanism, and a spindle assembly. The X-axis feed mechanism is fixedly installed on the worktable base. The X-axis slide plate is disposed on the X-axis feed mechanism and can reciprocate along the X-axis direction. The worktable is installed on the X-axis slide plate and moves along the X-axis direction with the X-axis slide plate. The column is vertically disposed at one end of the worktable base. The Z-axis slide plate is installed on the side of the column and slides along the Z-axis direction. The Y-axis feed mechanism is disposed on the Z-axis slide plate and can move up and down with the Z-axis slide plate, while simultaneously driving the spindle assembly to move along the Y-axis direction. The spindle assembly is disposed at the end of the Y-axis feed mechanism. The movement directions of the X-axis feed mechanism and the Y-axis feed mechanism are perpendicular to each other. The worktable and the spindle assembly are replaceable.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0031] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. Example 1

[0032] like Figure 1 As shown, this embodiment provides a woodworking horizontal five-axis linkage machining center, including a worktable base 1, an X-axis feed mechanism 2, an X-axis slide plate 3, a worktable, a column 5, a Z-axis slide plate 6, a Y-axis feed mechanism 7, and a spindle assembly.

[0033] The X-axis feed mechanism 2 is fixedly mounted on the worktable base 1, and the X-axis slide plate 3 is mounted on the X-axis feed mechanism 2 and reciprocates along the horizontal direction (i.e., the X-axis direction). The worktable is detachably mounted on the X-axis slide plate 3 and moves with the X-axis slide plate 3 in the X-axis direction to support and clamp the workpiece to be processed.

[0034] The column 5 is vertically mounted at one end of the worktable base 1. The Z-axis slide plate 6 is mounted on the side of the column 5 and slides along the Z-axis (up and down). The Y-axis feed mechanism 7 is mounted on the Z-axis slide plate 6 and moves up and down synchronously with it, while also driving the spindle assembly to move along the Y-axis (back and forth). The spindle assembly is detachably mounted at the end of the Y-axis feed mechanism 7, achieving high-precision displacement along the Y-axis. The X-axis feed mechanism 2 and the Y-axis feed mechanism 7 move in mutually perpendicular directions, forming a typical three-axis linkage system, providing a motion basis for five-axis linkage.

[0035] Specifically, in this embodiment, the worktable is a vacuum adsorption worktable 41, and the spindle assembly is a single-support cross spindle assembly 81.

[0036] The vacuum adsorption worktable 41 has a general-purpose structure that can firmly adsorb workpieces onto the worktable surface through vacuum negative pressure. It is suitable for processing wooden parts with regular shapes such as boards and boxes, and offers quick clamping and high positioning accuracy.

[0037] The single-support cross spindle assembly 81 adopts a cross-arranged spindle form with at least four independent tool positions, which can realize light cutting machining at multiple angles, and is especially suitable for one-time forming operations of solid wood parts.

[0038] This embodiment features a reasonable structural layout and a clear motion chain. Through the combination of a modularly designed worktable and spindle assembly, it achieves efficient and precise processing of workpieces with different shapes and process requirements. Example 2

[0039] like Figure 2As shown, this embodiment is a further optimization based on embodiment 1, specifically:

[0040] In this embodiment, the worktable is a clamp-type worktable 42, and the spindle assembly is still a single-support cross spindle assembly 81.

[0041] The clamp-type worktable 42 is fixedly mounted on the X-axis slide plate 3 and moves with it in the X-axis direction. This worktable is equipped with multiple adjustable clamping components, allowing for precise fixing of strip-shaped and columnar wooden parts of different sizes and shapes. It is particularly suitable for machining chair legs, backrests, and railing-like structural components.

[0042] The spindle assembly is still a single-support cross spindle assembly 81, which has a compact structure and staggered arrangement between spindles. It can install at least four tools at a time and is suitable for multi-angle light cutting, milling, hollowing and other processes.

[0043] By using a clamp-type positioning system and multi-tool spindle linkage, this structure significantly reduces the number of workpiece flipping operations, improves processing consistency and efficiency, and is especially suitable for small and medium-sized wood product manufacturing scenarios where similar parts are processed in batches. Example 3

[0044] like Figure 3 As shown, this embodiment is a further optimization based on embodiment 1, specifically:

[0045] In this embodiment, the worktable is still a vacuum adsorption worktable 41, and the spindle assembly is replaced with a dual-support multi-spindle assembly 82.

[0046] The dual-support multi-spindle assembly 82 is fixed at both ends to the output end of the Y-axis feed mechanism 7, which enhances structural rigidity and improves operational stability. With a large number of spindles arranged densely, multiple cutting tools can be installed simultaneously, making it suitable for high-load synchronous cutting of large-section wood or composite boards.

[0047] The vacuum adsorption worktable 41 maintains a versatile structure, adaptable to various planar workpieces such as sheet metal, door panels, and cabinets. Combined with a high-rigidity multi-spindle design, it can simultaneously process multiple feature surfaces or perform operations such as grooving and milling, significantly improving cutting efficiency.

[0048] This structure is suitable for scenarios where multiple blades are processed simultaneously, such as solid wood furniture parts and cabinet components, meeting the needs of medium-depth, high-frequency processing. Example 4

[0049] like Figure 4 As shown, this embodiment is a further optimization based on embodiment 1, specifically:

[0050] In this embodiment, the worktable is still the vacuum adsorption worktable 41, and the spindle assembly is replaced with a dual-support single spindle assembly 83, which has an automatic tool change function.

[0051] The dual-support single spindle assembly 83 is located at the end of the Y-axis feed mechanism 7, with support at both ends of the spindle. Its high structural rigidity makes it suitable for high-precision, high-stability machining applications. This spindle assembly is equipped with an automatic tool changer and tool magazine, allowing for rapid tool switching and making it suitable for multi-stage continuous machining of complex workpieces.

[0052] The vacuum adsorption worktable 41 provides a reliable clamping base, ensuring that the workpiece maintains positioning accuracy during tool changes and avoiding errors caused by multiple clamping operations.

[0053] This structure is particularly suitable for processing high-end custom furniture components, embossed patterns, inlaid panels, and other precision wood products with high detail requirements, and supports automated processing flows with complex paths. Example 5

[0054] like Figure 5 As shown, this embodiment is a further optimization based on embodiment 1, specifically:

[0055] In this embodiment, the worktable is a rotary worktable 43, and the spindle assembly is a single-support cross spindle assembly 81.

[0056] The rotating worktable 43 is set on the X-axis slide plate 3, and a gear disk structure is fixed at the bottom. A gear mechanism is installed at the front of the X-axis slide plate 3. The gear is driven to rotate by a servo motor. The gear meshes with the gear disk to realize the rotation of the worktable around the vertical axis.

[0057] This structure is suitable for multi-face continuous machining of large rotating bodies, cylindrical or irregular curved parts. The machining surface angle can be quickly switched by controlling the servo rotation angle, reducing the number of clamping operations and improving machining continuity.

[0058] The spindle assembly is a single-support cross spindle assembly 81, which supports multi-angle light cutting operations and is linked with the rotary worktable. It is suitable for processes such as curved surface trimming, irregular shaped parts, and multi-angle end face machining.

[0059] This embodiment has extremely high flexibility in processing, and is particularly suitable for the efficient processing of complex-shaped workpieces such as customized curved surfaces and large solid wood arc components.

[0060] The above embodiments describe the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Modifications and variations made by those skilled in the art without departing from the spirit and scope of this utility model should be protected within the scope of the appended claims.
