Description

Technical Field

[0001] This utility model relates to the field of CNC machining equipment, and in particular to a four-spindle dual-channel CNC machine tool. Background Technology

[0002] CNC machine tools are precision equipment that achieves automated machining through intelligent control systems. They are widely used in manufacturing and are mainly used for cutting, drilling, milling, and engraving of materials such as metals and non-metals. CNC machine tools can precisely control the tool movement path according to preset programs, enabling the mass production of complex parts, improving machining accuracy and efficiency, and are suitable for machining tasks requiring high precision and repeatability.

[0003] For example, related technologies propose a jewelry processing equipment, a type of CNC machine tool, primarily used for fine carving, setting, and surface treatment of precious metals, gemstones, and other materials to create exquisite jewelry and ornaments. The jewelry processing equipment proposed in these technologies typically employs a single-axis machining mode, meaning that only one spindle is used for cutting and shaping the workpiece. While this design is simple in structure, it suffers from low processing efficiency, frequent process switching, and poor adaptability to complex, multifaceted workpieces, leading to extended production cycles and an inability to efficiently meet diverse processing needs.

[0004] Existing single-axis machining methods in related technologies are inefficient and cannot meet the needs of fast-paced multi-specification machining. Therefore, there is an urgent need to propose a multi-spindle dual-channel CNC machine tool to achieve parallel machining, flexible switching between multiple tasks, and improve overall production efficiency and adaptability.

[0037] This application's four-spindle dual-channel CNC machine tool can be applied to workpiece processing such as jewelry making, metal workpiece processing, etc. In a preferred embodiment, refer to... Figure 1 and Figure 2 The four-spindle dual-channel CNC machine tool of this application includes:

[0038] Base 1;

[0039] The workpiece mounting mechanism 2 includes at least two mounting components 21 spaced apart along the width direction of the base 1, the mounting components 21 being used to mount the workpiece;

[0040] The machining mechanism 3 is located on the machine base 1 and on one side of the workpiece mounting mechanism 2. It includes at least two machining components 31, each machining component 31 is set corresponding to a mounting component 21, and each machining component 31 includes at least two machining spindles 310.

[0041] Tool magazine mechanism 4 is set on the machine base 1 and located on the side of the machining mechanism 3 facing away from the workpiece mounting mechanism 2. Tool magazine mechanism 4 is used to store tools for use by machining spindle 310.

[0042] In this embodiment, the operating principle of the four-spindle dual-channel CNC machine tool is based on a mechanism of multi-spindle parallel machining and independent or cooperative dual-channel control. By precisely coordinating the workpiece mounting mechanism 2 and the machining mechanism 3 on the machine base 1 through the CNC system, synchronous or asynchronous fine machining of the workpiece is achieved. Specifically:

[0043] Dual-channel design: The CNC machine tool of this application is divided into two independent machining channels, each channel can independently process at least one workpiece, or collaboratively process the same complex workpiece. This dual-channel separation operation allows for parallel machining operations, reducing process waiting time.

[0044] Multi-spindle linkage: Each machining component 31 is equipped with two machining spindles 310, each of which can work independently and supports the simultaneous execution of different processes.

[0045] The CNC machine tool operation process described in this application adopts an automated workflow, from workpiece preparation to output completion, emphasizing the parallelism of the dual channels and the cooperation of the spindle, wherein:

[0046] On the base 1, the workpiece is fixed to two mounting components 21 of the workpiece mounting mechanism 2. Each mounting component 21 can use a clamp to hold the workpiece, ensuring stable positioning of the workpiece.

[0047] The CNC system assigns tasks: the spindle in channel one performs the initial operation, while the machining spindle 310 simultaneously executes auxiliary operations. Meanwhile, the spindle in channel two processes another workpiece or the other side of the same workpiece, achieving parallel operation.

[0048] During the machining process, the machining spindle 310 can be moved to the tool magazine mechanism 4 to change the tool, or the tool can be changed before or after machining to adapt to different machining standards.

[0049] After processing is completed, the machining spindle 310 retracts, and the waste material can be collected through the waste collection port set in the machine base 1.

[0050] This application demonstrates significant advantages in jewelry processing and metal workpiece machining, primarily in efficiency, precision, and adaptability. The dual-channel parallel operation allows for the simultaneous processing of two workpieces, while the four-spindle linkage reduces process changeover time and significantly shortens production cycles. Compared to single-axis equipment, it is suitable for fast-paced, multi-specification requirements, such as the diverse jewelry production in the jewelry industry. It supports integrated multi-process machining of different specifications, facilitating the handling of irregularly shaped or multi-material workpieces.

[0051] Reference Figure 1 and Figure 2 In some embodiments, the at least two mounting components 21 proposed in this application include a first mounting component 211 and a second mounting component 212, wherein:

[0052] The first mounting assembly 211 includes a mounting base 2110, a swing drive 2111, and a tooling fixture 2112. The mounting base 2110 is disposed on the machine base 1, the swing drive 2111 is disposed on the mounting base 2110, and the tooling fixture 2112 is oscillatingly disposed on the mounting base 2110. The tooling fixture 2112 is used to mount the workpiece, and the swing drive 2111 is used to drive the tooling fixture 2112 to swing relative to the mounting base 2110, so as to drive the workpiece to swing relative to the machining spindle 310.

[0053] The second mounting component 212 has the same structure as the first mounting component 211.

[0054] In this embodiment, the working principle of the first mounting component 211 is based on a controllable swing mechanism. By integrating the mounting base 2110, the swing drive component 2111, and the tooling fixture 2112, the dynamic angle adjustment and stable fixation of the workpiece are achieved. Specifically:

[0055] Mounting base 2110 serves as a basic support structure, providing a stable installation platform. Mounting base 2110 can be directly or indirectly installed on base 1.

[0056] The swing drive component 2111 is mounted on the mounting base 2110 and can be powered by a motor or pneumatic drive to control the swing motion of the tooling fixture 2112. The drive component can achieve precise angular rotation or swing according to the instructions of the CNC system, and supports continuous or step adjustment.

[0057] The tooling fixture 2112 is pivotally mounted on the mounting base 2110 for directly clamping or adsorbing workpieces (such as jewelry blanks). The fixture is designed to allow the workpiece to pivot relative to the machining spindle 310 while in a fixed state, driven by the pivoting drive 2111, thereby changing the workpiece's posture relative to the machining spindle 310.

[0058] Reference Figure 1 and Figure 2 In some embodiments, the two processing components 31 proposed in this application include a first processing component 311 and a second processing component 312. The first processing component 311 includes a spindle drive member 3110. At least two processing spindles 310 are disposed at the output end of the spindle drive member 3110. The spindle drive member 3110 is used to drive the two processing spindles 310 to move toward or away from the workpiece mounting mechanism 2.

[0059] In a preferred embodiment, the first machining component 311 proposed in this application includes a spindle drive component 3110, and at least two machining spindles 310 are disposed at the output end of the spindle drive component 3110. The spindle drive component 3110 is used to drive the two machining spindles 310 to move between the workpiece mounting mechanism 2 and the tool magazine mechanism 4.

[0060] The second processing component 312 has the same structure as the first processing component 311.

[0061] In this embodiment, the first machining component 311 operates based on an integrated drive and multi-spindle linkage mechanism. The spindle drive component 3110 coordinates the movement of at least two machining spindles 310, achieving efficient machining and tool changing operations. Specifically:

[0062] The spindle drive component 3110, as the core power component, is located in the machining component 31 and provides driving force and motion control. For example, the two machining spindles 310 at the output end can be precisely controlled by a mechanism such as a servo motor or a linear guide to achieve translational or positioning movements along a specified path, so as to move the machining spindles 310 to the workpiece mounting mechanism 2 for machining or to the tool magazine mechanism 4 for tool changing.

[0063] The machining spindle 310 has at least two spindles fixed to the output end of the spindle drive component 3110. Each spindle is independently equipped with a tool interface, supporting operations such as rotary cutting and drilling. The spindles can work synchronously or asynchronously; while one machining spindle 310 is performing the current machining task, the other can prepare or wait for a tool change.

[0064] The spindle drive component 3110 drives two spindles to reciprocate between the workpiece mounting mechanism 2 (which fixes the position of the workpiece) and the tool magazine mechanism 4 (which stores the tools). This design allows the spindles to quickly move from the machining area to the tool magazine area for automatic tool changing, and then return to the workpiece area to continue operation, reducing downtime.

[0065] Reference Figure 1 and Figure 2 In some embodiments, the four-spindle dual-channel CNC machine tool proposed in this application further includes a gantry 5, which includes two spaced-apart support columns 51 and a crossbeam 52 connecting the two support columns 51. The crossbeam 52 is located on the upper side of the workpiece mounting mechanism 2; the spindle drive component 3110 includes:

[0066] A transverse drive unit 3111 is disposed on the crossbeam 52. The transverse drive unit 3111 is used to drive the machining spindle 310 to move horizontally relative to the workpiece mounting mechanism 2 along the width direction of the machine base 1.

[0067] The lifting drive 3112 is located at the output end of the transverse drive 3111. The output end of the lifting drive 3112 is provided with at least two machining spindles 310. The lifting drive 3112 is used to drive the machining spindles 310 to approach or move away from the workpiece mounting mechanism 2 in the vertical direction.

[0068] In this embodiment, the spindle drive component 3110 proposed in this application operates based on a multi-axis linkage drive mechanism. By integrating the transverse drive component 3111 and the lifting drive component 3112 through the gantry frame 5 structure, the machining spindle 310 achieves precise positioning and movement in both horizontal and vertical directions. Specifically:

[0069] The supporting function of the gantry frame 5: The two support columns 51 and the crossbeam 52 form a stable frame to ensure the rigidity and accuracy of the drive components during movement. The upper position of the crossbeam 52 facilitates the spindle to approach the workpiece mounting mechanism 2 from above.

[0070] The transverse drive unit 3111 is mounted on the crossbeam 52 and acts as a horizontal motion controller. Using a guide rail or lead screw, it drives the entire spindle assembly to slide horizontally relative to the workpiece mounting mechanism 2 along the width direction of the machine base 1. This motion allows the spindle to traverse different processing areas laterally, supporting switching between channels or covering wide workpieces.

[0071] The lifting drive 3112 is installed at the output end of the transverse drive 3111, and its output end is directly connected to at least two machining spindles 310. The lifting mechanism controls the vertical movement of the spindle, allowing it to approach the workpiece for cutting or move away for tool changing and obstacle avoidance.

[0072] Reference Figure 1 and Figure 2 In some embodiments, the number of lifting drive components 3112 proposed in this application is two, with the two lifting drive components 3112 being spaced apart at the output end of the transverse drive component 3111, and each machining spindle 310 being correspondingly disposed at the output end of one lifting drive component 3112.

[0073] In this embodiment, the lifting drive component 3112 operates based on an independent vertical motion control mechanism. Two spaced-apart lifting drive components 3112 drive the corresponding machining spindles 310, achieving precise lifting and positioning of the spindles in the vertical direction. Specifically:

[0074] Two lifting drive units 3112 are installed parallel to each other at the output end of the transverse drive unit 3111. Each drive unit operates independently, powered by a hydraulic or electric mechanism, ensuring that its respective spindle can be vertically adjusted without interference. This spacing design avoids mechanical conflict between the spindles and supports synchronous or asynchronous operation.

[0075] Each lifting drive unit 3112 is connected to a machining spindle 310 at its output end. When the drive unit is activated, the spindle moves along the vertical axis to approach the workpiece for cutting, drilling, or other operations, or moves away from the workpiece to change tools, avoid obstacles, or switch processes. The CNC system coordinates the speed and stroke of the drive unit to achieve smooth transitions and precise height matching.

[0076] Combined with the horizontal movement of the transverse drive 3111, the lifting drive 3112 adds a vertical degree of freedom, forming a two-dimensional or multi-dimensional path control, which makes it easier for the spindle to adapt to different workpiece heights or multi-layer processing requirements.

[0077] Reference Figure 1 and Figure 2 In some embodiments, the tool magazine mechanism 4 proposed in this application is spaced apart on one side of the workpiece mounting mechanism 2, and the tool magazine mechanism 4 includes at least one tool mounting assembly 41 slidably disposed on the base 1.

[0078] In this embodiment, the tool magazine mechanism 4 proposed in this application uses a tool mounting assembly 41 that is slidably mounted on the machine base 1 to achieve orderly storage of tools and supply the tool changing needs of the machining spindle 310. Specifically:

[0079] The tool magazine mechanism 4 is located on one side of the workpiece mounting mechanism 2, ensuring it does not interfere with the machining area. It also allows the tool mounting assembly 41 to slide to the corresponding tool change position on the machining spindle 310 for tool changing operations, such as moving it directly below the machining spindle 310. The tool mounting assembly 41 stores multiple tools. When the machining spindle 310 needs to be changed, the assembly is moved to the corresponding tool change position by external force (such as manual pushing or a drive mechanism), while the spindle remains stationary, allowing for direct tool access. After completion, the assembly can be reset by external force, ready for the next operation.

[0080] At least one tool mounting assembly 41 is slidably mounted on the machine base 1. Its sliding is facilitated by a guide rail or slider mechanism, allowing it to be moved along the machine base 1 by external force. The tool mounting assembly 41 is designed with multiple tool positions for fixing different types of tools. The sliding motion aligns a specific tool position with the stationary machining spindle 310, facilitating the machining spindle 310 to grip or release the tool.

[0081] Reference Figure 1 and Figure 2 In some embodiments, the four-spindle dual-channel CNC machine tool proposed in this application includes a base 6, a sliding assembly 7, and a mounting plate 8. The base 6 is disposed on the machine base 1, and the mounting plate 8 is slidably connected to the base 6 through the sliding assembly 7. The tool mounting assembly 41 is mounted on the mounting plate, and the sliding assembly 7 is used to drive the mounting plate 8 by external force, so as to drive the tool mounting assembly 41 disposed on the mounting plate 8 to move in a direction toward or away from the machining spindle 310.

[0082] In this embodiment, the working principle is based on the sliding connection and external force driving mechanism. Through the cooperation of the base 6, the sliding component 7 and the mounting plate 8, the dynamic positioning and movement of the tool mounting component 41 are realized.

[0083] Specifically:

[0084] The base 6 serves as a fixed foundation, set on the base 1, providing a stable support platform.

[0085] The sliding component 7 connects the base 6 and the mounting plate 8, and can achieve smooth sliding of the mounting plate 8 using a guide rail or roller mechanism. As a force transmission medium, it allows external forces (such as human power or driving devices such as motors or cylinders) to act on the mounting plate 8, pushing it to move relative to the base 6, thereby driving the tool mounting component 41 mounted on the mounting plate 8 to move.

[0086] Mounting plate 8 is connected to base 6 via sliding assembly 7 and is used to support tool mounting assembly 41. When external force drives mounting plate 8, it causes tool mounting assembly 41 to move linearly in a specified direction (towards or away from machining spindle 310), so that the tool position is aligned with the spindle, facilitating tool change operation.

[0087] Reference Figure 1and Figure 2 In some embodiments, the tool mounting assembly 41 proposed in this application includes:

[0088] Tool changer drive unit 411 is mounted on mounting plate 8;

[0089] At least two drive shafts 412 are provided, each drive shaft 412 is spaced apart on the mounting plate 8 along the length of the machine base 1, the drive shafts 412 are rotatably provided on the mounting plate 8 and are connected to the output end of the tool changer drive 411.

[0090] An annular chain 413 is sleeved on each drive shaft 412;

[0091] Multiple tool holders 414 are distributed at intervals along the entire circle of the annular chain 413. The tool holders 414 are used to store tools for the machining spindle 310 to access.

[0092] The tool changer drive 411 is used to drive the ring chain 413 to move, thereby causing any tool holder 414 to move toward or away from the machining spindle 310.

[0093] In this embodiment, the working principle of the tool mounting assembly 41 is based on a rotary cyclic transmission mechanism. The tool changer 411 drives the annular chain 413 to move, thereby achieving dynamic positioning of the tool holder 414 and tool supply. Specifically:

[0094] At least two drive shafts 412 are spaced apart along the length of the machine base 1 on the mounting plate 8 and are rotatably connected to ensure stable support and transmission path for the ring chain 413. The drive shafts 412 serve as fulcrums, allowing the ring chain 413 to rotate around them. At least one of the two drive shafts 412 is connected to the output end of the tool changer drive 411, so that the tool changer drive 411 drives the drive shaft 412 to rotate.

[0095] The annular chain 413 is sleeved on each drive shaft 412 to form a closed loop structure. It acts as a transmission medium. When the tool changer drive unit 411 provides power to drive the drive shaft 412 to rotate, the annular chain 413 rotates or slides with the drive shaft 412, causing the attached tool holder 414 to move as a whole.

[0096] Multiple tool holders 414 are distributed at intervals along the full circle of the annular chain 413, and each tool holder 414 is used to store a specific tool (such as a cutting tool or a drill bit). Through the movement of the annular chain 413, the tool holders 414 can be cyclically moved so that the target tool holder 414 is aligned with the machining spindle 310, which facilitates the spindle to grab or release the tool.

[0097] The tool changer drive 411 is mounted on the mounting plate 8 and serves as a power source to drive the ring chain 413 to move, thereby controlling the tool holder 414 to approach the machining spindle 310 for tool change, or to move away for reset and storage.

[0098] Reference Figure 1 and Figure 2 In some embodiments, the tool mounting assembly 41 proposed in this application embodiment is two in number. The four-spindle dual-channel CNC machine tool also includes a transmission assembly 9. The transmission assembly 9 includes a driven gear 91, a driving gear 92 and a transmission belt. The driving gear 92 is located at the output end of the tool changer drive 411. There are two driven gears 91. The two driven gears 91 are respectively located on the transmission shafts 412 of the two tool mounting assemblies 41. The transmission belt is sleeved on the driving gear 92 and the driven gear 91.

[0099] In this embodiment, the working principle is based on synchronous transmission and multi-component linkage mechanism. The transmission component 9 connects the tool changer drive 411 to the two tool mounting components 41, achieving unified driving and cyclical supply of tools. Specifically:

[0100] The transmission assembly 9 includes a drive gear 92, a driven gear 91, and a transmission belt, serving as a power transmission system. The drive gear 92 is located at the output end of the tool changer drive 411, and the driven gear 91 is respectively mounted on the drive shafts 412 of the two tool mounting assemblies 41. The transmission belt is sleeved to connect the drive gear 92 and the driven gear 91, ensuring that the power is evenly distributed from the drive to the two assemblies, achieving synchronous rotation.

[0101] There are two tool mounting assemblies 41. Each assembly receives power from the driven gear 91 via a drive shaft 412, supporting the movement of the ring chain 413 and the cyclic positioning of the tool holder 414. Both machining spindles 310 of any machining assembly 31 can be used simultaneously for tool changing.

[0102] The tool changer drive unit 411 serves as a power source, driving the drive gear 92 to rotate. Through the transmission belt and driven gear 91, it links the two tool mounting assemblies 41, causing the tool holder 414 to move toward the machining spindle 310 for tool changing, or away from it to reset.
