[0044] a machine base 1;

[0045] a workpiece mounting mechanism 2 disposed on the machine base 1 for mounting a workpiece;

[0046] The tool changing mechanism 3 is horizontally spaced apart from the workpiece mounting mechanism 2, and includes a rotating driving member 31 arranged on the machine base 1, a mounting plate 32 arranged on an output end of the rotating driving member 31, and a plurality of tool holders 33 arranged on the mounting plate 32, each of the tool holders 33 is annularly and spacedly distributed on the mounting plate 32:

[0047] The machining mechanism 4 includes a machining driving assembly 41 arranged on the machine base 1 and at least one machining spindle 42 connected to an output end of the machining driving assembly 41, and the machining driving assembly 41 is used to drive the machining spindle 42 to move in a direction towards or away from the workpiece mounting mechanism 2 or the tool holder 33;

[0048] The rotating driving member 31 is used to drive the mounting plate 32 to rotate, so as to drive any tool holder 33 to rotate towards the machining spindle 42.

[0049] In the embodiment, the machine base 1 is used as a mounting base of each mechanism, the workpiece mounting mechanism 2 is mounted on the machine base 1, and is used to stably clamp a workpiece and provide a basic support for machining. The tool changing mechanism 3 is composed of the rotating driving member 31, the mounting plate 32 and the plurality of tool holders 33, the plurality of tool holders 33 are annularly and spacedly distributed on a circumferential side of the mounting plate 32, the rotating driving member 31 drives the mounting plate 32 to rotate, so as to drive the plurality of tool holders 33 arranged on the mounting plate 32 to rotate, through rotating the mounting plate 32, any tool holder 33 can be quickly moved to a position corresponding to the machining spindle 42, the machining driving assembly 41 drives the machining spindle 42 to move in a direction towards or away from the workpiece mounting mechanism 2 or the tool holder 33, so as to realize that the machining spindle 42 processes a workpiece clamped by the workpiece mounting mechanism 2, or realizes that the machining spindle 42 and the tool holder 33 complete a tool changing operation, and complete a quick switching of a tool on the machining spindle 42 and a tool on the tool holder 33.

[0050] The movement of the machining spindle 42 driven by the machining driving assembly 41 can be horizontal direction movement relative to a horizontal plane of the machine base 1, or vertical direction movement relative to the horizontal plane of the machine base 1, specifically, the machining driving assembly 41 drives the machining spindle 42 to move horizontally relative to the horizontal plane of the machine base 1, the horizontal direction includes a first horizontal direction and a second horizontal direction, the first horizontal direction is different from the second horizontal direction, the direction in which the machining driving assembly 41 drives the machining spindle 42 to move back and forth between the tool changing mechanism 3 and the workpiece mounting mechanism 2 is defined as the first horizontal direction, hereinafter referred to as the X direction, the direction in which the machining driving assembly 41 drives the machining spindle 42 to move transversely relative to the tool changing mechanism 3 and the workpiece mounting mechanism 2 is defined as the second horizontal direction, hereinafter referred to as the Y direction, and the direction in which the machining driving assembly 41 drives the machining spindle 42 to move vertically relative to the tool changing mechanism 3 and the workpiece mounting mechanism 2 is defined as a vertical direction, hereinafter referred to as the Z direction, the above-mentioned X direction, Y direction and Z direction are exemplary naming names, and are not limitative.

[0051] In the machining process, first, the workpiece to be machined is installed on the workpiece mounting mechanism 2 to ensure that the workpiece is stable and accurately positioned during machining.

[0052] When the tool needs to be replaced, the rotary drive 31 drives the mounting plate 32 to rotate, selects the appropriate tool holder 33, and makes the tool holder 33 rotate to a position aligned with the machining spindle 42.

[0053] The machining drive assembly 41 drives the machining spindle 42 to approach the target tool holder 33 to complete the tool replacement, which can be divided into a disassembly process and a loading process. The machining spindle 42 can first exchange the tool to be replaced with the empty tool holder 33, and then place the tool to be replaced in the tool holder 33. The rotary drive 31 or the machining drive assembly 41 drives the machining spindle 42 to the position of another tool holder 33 to exchange the tool with the tool holder 33. Specifically, when the rotary drive 31 drives the mounting plate 32 to rotate so that the tool holder 33 on the mounting plate 32 rotates, the machining spindle 42 can be stationary, and the rotary drive 31 can switch the positions of different tool holders 33 by rotating the mounting plate 32. When the machining drive assembly 41 drives the machining spindle 42 to move, the machining spindle 42 can move in the X, Y, and Z directions between multiple tool holders 33, while the mounting plate 32 and the tool holders 33 thereon can be stationary or can rotate as described above to achieve a cooperative tool changing process to save tool changing time.

[0054] In some embodiments, the rotary drive 31 can be a rotary motor whose output end is directly connected to the mounting plate 32, or it can be indirectly connected through a driving motor, a synchronous pulley, and a connecting shaft. The mounting plate 32 is connected to the driven pulley of the synchronous pulley through the connecting shaft, and the driving motor is connected to the driving pulley of the synchronous pulley, so that when the rotary drive 31 outputs driving force, the mounting plate 32 can rotate relative to the machine base 1.

[0055] The multi-axis numerical control machining equipment with the above structure can achieve the following effects:

[0056] First, improve the machining efficiency: through the design of multiple tool holders 33 arranged in a ring on the mounting plate 32 and the quick rotation tool changing function, the tool changing time can be greatly shortened.

[0057] Multiple machining spindles 42 can be designed to achieve simultaneous machining, and multiple tool holders 33 can be provided to simultaneously replace the tools of multiple machining spindles 42, thereby improving the production efficiency of the entire equipment.

[0058] Secondly, the machining precision is enhanced, the workpiece can be clamped once to complete multi-position machining, the positioning error caused by multiple clamping is reduced, complex machining requirements can be adapted, multi-axis design is combined with flexible tool changing mechanism, and complex machining of multiple surfaces or different positions of the workpiece can be easily realized.

[0059] Thirdly, the operation cost is reduced, the automation degree is high, manual intervention is reduced, and the technical requirements and working strength of the operator are reduced.

[0060] Fourthly, the modular extension is strong, and the independent design of the tool changing mechanism 3 and the machining mechanism 4 enables the equipment to have good expansibility, and the number of tool types or machining spindles 42 can be increased according to requirements.

[0061] In summary, the multi-axis numerical control machining equipment improves the comprehensive performance of the numerical control machining equipment by efficient tool changing design and accurate machining control, provides an efficient and accurate solution for complex machining scenarios, greatly improves the tool changing efficiency of the machining spindle 42, and further improves the machining efficiency of the whole equipment, and is practical and efficient.

[0062] Reference Figures 1 to 4 In some embodiments, the mounting plate 32 is provided in a polygonal plate shape, and at least one tool holder 33 is arranged on each side of the mounting plate 32.

[0063] In this embodiment, the mounting plate 32 is designed as a polygonal plate, and at least one tool holder 33 is arranged on each side of the mounting plate 32. This layout uniformly distributes the plurality of tool holders 33 along the edges of the mounting plate 32, forms a plurality of tool positions, and can realize storage and switching of a plurality of tools.

[0064] The polygonal shape optimizes the planar space distribution of the mounting plate 32, so that the spaced positions of the tool holders 33 can accommodate more tools, and at the same time, the movement of the tool changing mechanism 3 will not be affected by the dense arrangement. Installing one tool holder 33 on each side can ensure that the installation position of each tool holder 33 is installed and stable, reduce the error during tool changing, and ensure the tool changing accuracy. The edge and corner structure of the polygonal plate is convenient for positioning, and when the corresponding tool holder 33 is turned to the machining spindle 42 position by rotating the mounting plate 32 of the tool changing mechanism 3, the target tool holder 33 can quickly align with the machining spindle 42 position, thereby shortening the tool changing time.

[0065] In some embodiments, a circular mounting plate 32 design can also be used. Compared with the circular design, the polygonal design has clear boundaries and positioning reference points, which can simplify the installation and docking structure of the tool holder 33, and at the same time, increase the stability of the tool holder 33. By adjusting the number of sides or the length of the polygon, the number and distribution of the tool holders 33 can be flexibly changed to adapt to different machining requirements.

[0066] The tool changing mechanism 3 controls the rotation of the mounting plate 32 through the rotary drive 31. The rotation of the mounting plate 32 drives each tool holder 33 on the polygonal plate to rotate along a circular path, that is, the mounting plate 32 is driven to rotate around the output end of the rotary drive 31. When the target tool holder 33 rotates to the position of the machining spindle 42, the tool changing mechanism 3 stops driving the mounting plate 32 to rotate, so that the mounting plate 32 is temporarily installed at the interaction position to wait for the tool changing interaction action of the machining spindle 42.

[0067] After the tool changing is completed, the machining drive assembly 41 controls the machining spindle 42 to move to the workpiece position to continue to perform the machining task. If tool changing is needed again, the rotary drive 31 rotates the mounting plate 32 again to select the next tool holder 33 so that it is opposite to the machining spindle 42.

[0068] The polygonal mounting plate 32 is rotated accurately, so that the tool changing mechanism 3 can quickly position the target tool holder 33, and the tool changing efficiency is significantly improved. Through the polygonal design and the flexible distribution of the tool holders 33, the tool changing mechanism 3 can accommodate tools of various specifications to meet diversified machining requirements.

[0069] In summary, the polygonal mounting plate 32 provides a basic support for the efficient cooperation of the tool changing mechanism 3 and the machining mechanism 4, solves the problem of low tool changing efficiency of the traditional tool changing mechanism, and significantly improves the flexibility and stability of the equipment.

[0070] Referring to Figure 3 and Figure 4 In some embodiments, the number of machining spindles 42 is multiple, and the number of tool holders 33 corresponding to the number of machining spindles 42 is set on each side of the mounting plate 32.

[0071] In this embodiment, the number of tool holders 33 set on each side of the mounting plate 32 needs to be consistent with the number of machining spindles 42, for example, when the number of machining spindles 42 is two, two tool holders 33 need to be set on each side of the mounting plate 32, and so on.

[0072] If the mounting plate 32 is an n-sided polygon, and there are two tool holders 33 on each side, the total number of tool holders 33 is: total number of tool holders 33 = number of tool holders 33 set on each side of the polygon × number of sides of the polygon. Assuming that the number of tool holders 33 set on each side of the polygon is 4 and the number of sides of the polygon is 6, 4*6 = 24 tool holders 33 need to be set.

[0073] When two tool holders 33 are arranged on each side, the two tool holders 33 are arranged at intervals on the side and correspond to the positions of the two machining spindles 42. By analogy, when four tool holders 33 are arranged on each side, the four tool holders 33 can be divided into two groups, and the two tool holders 33 in each group are arranged at intervals, and the two groups of tool holders 33 are arranged at intervals on the side, and the two tool holders 33 in each group correspond to the positions of the two machining spindles 42. Here, only exemplary examples are given, but are not limited.

[0074] When the number of machining spindles 42 is two, and two tool holders 33 corresponding to the two machining spindles 42 are arranged on each side of the mounting plate 32, in order to realize simultaneous tool changing of the two machining spindles 42, the numerical control system can be used to drive the two machining spindles 42 and the rotary drive 31 to drive the mounting plate 32 to rotate the tool holder 33, and synchronous control is performed.

[0075] The tool changing process can be briefly described as follows:

[0076] The machining spindle 42 is stationary at a predetermined tool changing interaction position, or is driven by the machining driving assembly 41 to the predetermined tool changing interaction position, the rotary drive 31 rotates the mounting plate 32, and the target tool holder 33 is aligned with the two machining spindles 42.

[0077] The machining spindle 42 moves to the position of the tool holder 33: the machining driving assembly 41 drives the two machining spindles 42 to move in the direction of the respective aligned tool holders 33. The machining spindle 42 unloads the current tool to the tool holder 33 through the automatic clamping system of the machining spindle 42. At this time, the rotary drive 31 drives the mounting plate 32 again to rotate the tool holder 33 on the other side of the mounting plate 32 to the position corresponding to the machining spindle 42, and the aforementioned tool holder 33 unloaded with the tool is away from the machining spindle 42, and the machining spindle 42 clamps a new tool from the tool holder 33 on the other side of the mounting plate 32 and completes the installation. After the tool changing is completed, the machining spindle 42 moves to the workpiece mounting mechanism 2 position and continues the machining task.

[0078] The tool changing paths of the two machining spindles 42 are designed to be parallel but not overlapped. The numerical control system needs to support multi-channel synchronous tool changing logic to ensure that the two machining spindles 42 simultaneously complete the unloading and clamping of the tool. The driving assemblies of the two machining spindles 42 need to independently control the motion paths to enable them to accurately dock to the respective tool holders 33. The mounting plate 32 ensures that the tool holder 33 is accurately aligned with the machining spindle 42 after each rotation.

[0079] In some embodiments, sensors can also be provided to monitor the tool changing process in real time to ensure that the tool is docked firmly and the tool changing action is completed without error.

[0080] The embodiments of the utility model realize the following effects by setting the above structure:

[0081] Significant improvement in tool changing efficiency: through simultaneous tool changing of two machining spindles 42, the tool changing time is greatly shortened, improving the production efficiency of the equipment.

[0082] Optimization of processing rhythm: the design of synchronous tool changing enables the equipment to quickly connect the processing tasks, reduces the waiting time, and improves the overall processing rhythm.

[0083] Enhanced processing flexibility: the distributed design of the tool holder 33 and the tool changing mechanism enable the equipment to quickly adapt to the complex processing needs of various workpieces.

[0084] High efficiency automation: multi-channel control and automatic tool changing process reduce the need for manual intervention, improving the automation level of the equipment.

[0085] In summary, through reasonable tool holder 33 quantity setting and synchronous tool changing design, the embodiment realizes efficient collaborative tool changing of multiple machining spindles 42, significantly improving tool changing efficiency, processing efficiency and equipment performance.

[0086] Reference Figure 3 In some embodiments, the tool holder 33 proposed by the utility model embodiment includes a base 331 and two clamping jaws 332, the base 331 is arranged on the mounting plate 32, and the two clamping jaws 332 are arranged on the two sides of the base 331 in the horizontal direction to clamp the tool head for the machining spindle 42.

[0087] In the embodiment, the tool holder 33 is composed of a base 331 and two clamping jaws 332, wherein the base 331 is mounted on the mounting plate 32 to provide stable support for the tool holder 33. The two clamping jaws 332 are arranged on the two sides of the base 331 in the horizontal direction, which can be connected to the base 331 or the mounting plate 32 or both, and can firmly hold the tool head through clamping force to prevent the tool head from falling off or moving when the mounting plate 32 rotates or the machining spindle 42 is connected.

[0088] A controllable clamping space is formed between the two clamping jaws 332, and when the tool head is inserted into the clamping jaw 332, the clamping jaw 332 provides moderate clamping force through the elastic mechanism or locking mechanism. When the machining spindle 42 takes the tool head, the elastic mechanism or locking mechanism of the clamping jaw 332 is slightly loosened to allow the spindle to smoothly clamp the tool head. The loosening operation can be realized by the deformability of the elastic mechanism and the locking mechanism, or by external driving elements such as air cylinder drive.

[0089] The tool head is installed between the clamping jaws 332 of the tool holder 33 before installation or tool changing. The base 331 provides support, and the clamping jaws 332 provide stable clamping force to ensure the installation of the tool head position. When the machining spindle 42 needs to be changed, the installation plate 32 rotates to align the target tool holder 33 with the machining spindle 42. The machining spindle 42 moves to the position of the tool holder 33 and is connected to the connecting end of the tool head. The spindle grabs the tool head through its clamping device, while the clamping jaws 332 of the tool holder 33 are gradually loosened to release the tool head. When the old tool is returned, the spindle inserts the tool head between the clamping jaws 332, and the clamping jaws 332 restore the clamping of the tool head through the elastic mechanism to complete the storage. This tool changing process is only illustrative, and the actual operation may be different depending on the selected machining spindle 42. Therefore, it is not limited here and is only illustrative for easy understanding.

[0090] The base 331 and the clamping jaws 332 of the tool holder 33 ensure stable storage of the tool head in the non-working state and prevent the tool head from falling off due to vibration or rotation of the installation plate 32. The tool holder 33 is designed to enable the machining spindle 42 to quickly access and return the tool head, shorten the tool changing time, and improve the machining efficiency.

[0091] In summary, the tool holder 33 of the embodiment of the utility model provides reliable storage and tool changing support for the tool through the reasonable design of the base 331 and the clamping jaws 332, significantly improves the efficiency and stability of tool changing, and is an important part of efficient machining.

[0092] Referring to Figure 1 and Figure 2 In some embodiments, the machine base 1 proposed in the embodiment of the utility model comprises a portal frame 11, the portal frame 11 comprises two side plates 111 arranged at intervals, and a connecting plate 112 located between the two side plates 111, and the connecting plate 112 connects the two side plates 111; the machining driving assembly 41 comprises:

[0093] The first transfer driving member 411 is arranged in the portal frame 11;

[0094] The mounting seat 412 is slidably connected to the portal frame 11 and connected to the output end of the first transfer driving member 411, and at least one machining spindle 42 is connected to the mounting seat 412;

[0095] The first transfer driving member 411 is used to drive the mounting seat 412 to move relative to the portal frame 11, so as to drive the machining spindle 42 to move along the horizontal direction to the workpiece mounting mechanism 2 or the tool changing mechanism 3.

[0096] In this embodiment, the first transfer driving member 411 drives the mounting seat 412 to slide along the horizontal guide rail of the gantry 11 through the linkage of the control output end and the mounting seat 412, specifically, moves in the X direction, so that the mounting seat 412 drives the machining spindle 42 arranged thereon to move in the horizontal direction, realizing efficient positioning of the machining spindle 42 between the workpiece mounting mechanism 2 and the tool changing mechanism 3. The machining spindle 42 arranged on the mounting seat 412 can be directly connected to the mounting seat 412 or connected through an intermediate connecting piece. The intermediate connecting piece can be a plate body, a seat body, and a driving member for installation. Here, only an exemplary distance is provided, and no limitation is made.

[0097] The first transfer driving member 411 is usually driven by a servo motor or a stepping motor, and converts the rotary motion into horizontal linear motion through a lead screw, a gear rack, or a linear guide rail system. The transfer path, speed, and precision are accurately managed by a PLC control system or the like, ensuring that the machining spindle 42 can accurately reach the target position.

[0098] Initialization positioning: When the machining task starts, the first transfer driving member 411 drives the mounting seat 412 to position the machining spindle 42 to the initial position (usually between the workpiece mounting mechanism 2 or the tool changing mechanism 3).

[0099] Moving to the machining position: When the machining spindle 42 needs to process the workpiece, the first transfer driving member 411 controls the mounting seat 412 to move relative to the gantry 11 along the gantry 11 horizontally, and accurately positions the machining spindle 42 to the machining area of the workpiece mounting mechanism 2.

[0100] Moving to the tool changing position: When the tool needs to be changed, the first transfer driving member 411 drives the mounting seat 412 to move to the tool changing mechanism 3, so that the machining spindle 42 is aligned with the tool holder 33, and the tool loading and unloading is completed.

[0101] In multi-process machining, the first transfer driving member 411 dynamically adjusts the horizontal position of the machining spindle 42 according to the machining program to meet the machining requirements of multiple parts or different angles of the workpiece.

[0102] The gantry 11 and the first transfer driving member 411 with the above structure realize the following effects in this embodiment:

[0103] Realize high-precision horizontal motion: The first transfer driving member 411 ensures that the movement of the machining spindle 42 in the horizontal direction has high positioning accuracy through precise control, providing protection for complex machining tasks.

[0104] Improve tool changing efficiency: The first transfer driving member 411 can quickly drive the machining spindle 42 to the tool changing position, cooperate with the tool changing mechanism 3, realize efficient tool changing, and reduce non-processing time.

[0105] Support complex processing tasks: by flexible moving the position of the machining spindle 42, support the multi-surface, multi-feature processing of different parts of the workpiece, adapt to complex processing requirements.

[0106] In summary, the first moving and loading driving member 411 undertakes the tasks of accurate positioning and flexible adjustment of the machining spindle 42 in the horizontal direction. The numerical control machining equipment of the embodiment of the utility model can realize the quick switching of workpiece machining and tool replacement by setting the first moving and loading driving member 411, and significantly improves the machining efficiency, precision and adaptability of the equipment.

[0107] Referring to Figure 1 and Figure 2 Further, in some embodiments, the machining driving assembly 41 proposed in the embodiment of the utility model further comprises:

[0108] The second moving and loading driving member 413 is arranged on the mounting seat 412, and at least one machining spindle 42 is connected to the output end of the second moving and loading driving member 413. The second moving and loading driving member 413 is used to drive the machining spindle 42 to move horizontally along the horizontal direction relative to the workpiece mounting mechanism 2 or the tool changing mechanism 3.

[0109] In the embodiment, the second moving and loading driving member 413 is mounted on the mounting seat 412, and the output end thereof is directly connected with the machining spindle 42, which is used to control the horizontal movement of the machining spindle 42 relative to the workpiece mounting mechanism 2 or the tool changing mechanism 3 in the horizontal direction. The direction of the horizontal movement is the Y direction recorded in the foregoing embodiment.

[0110] The second moving and loading driving member 413 works in cooperation with the first moving and loading driving member 411. The first moving and loading driving member 411 is responsible for the horizontal movement in the X direction, so that the machining spindle 42 can move horizontally in the X direction. The second moving and loading driving member 413 is responsible for the horizontal movement of the machining spindle 42 in the Y direction, and cooperates with the first moving and loading driving member 411 to perform fine adjustment and transverse positioning during machining, etc., so that the equipment has higher flexibility.

[0111] In the processing process, the second moving driving member 413 can drive the processing spindle 42 to move horizontally and transversely, complete the fine adjustment of the specific processing path, and be suitable for cutting, drilling or multi-point processing operation. The second moving driving member 413 is not only used for the horizontal movement of the processing spindle 42 along the Y direction in the processing, but also used for cooperating with the tool changing mechanism 3 to realize tool changing. As described in the foregoing embodiment, each side of the mounting plate 32 is provided with two groups of tool holders 33, each group of tool holders 33 includes a plurality of tool holders 33 corresponding to the number of the processing spindle 42. When the first moving driving member 411 moves the mounting seat 412 to the target area, the processing spindle 42 is aligned with the tool changing mechanism 3, and then the second moving driving member 413 is started to drive the processing spindle 42 to dock the tool holder 33 of the tool changing mechanism 3, so as to ensure the accurate loading and unloading of the tool. The transverse adjustment function can also reduce the demand for the overall movement of the mounting seat 412 in the tool changing process, and improve the tool changing efficiency.

[0112] In summary, the second moving driving member 413 plays a role in driving the processing spindle 42 to move transversely (in the Y direction) in the embodiment, and realizes the position compensation effect in the transverse direction (Y direction), and forms an efficient cooperation mechanism with the first moving driving member 411. Through the function of driving the processing spindle 42 to move transversely (in the Y direction), the positioning accuracy and flexibility of the processing spindle 42 are improved, the execution efficiency of tool changing and complex processing tasks is further optimized, and the overall performance of the equipment is significantly enhanced.

[0113] With reference to Figure 1 and Figure 2 In some embodiments, the processing driving assembly 41 provided in the embodiment of the utility model further comprises:

[0114] The vertical driving member 414 is connected to the output end of the second moving driving member 413 at one end, and is an output end at the other end. At least one processing spindle 42 is arranged at the output end of the vertical driving member 414. The vertical driving member 414 is used to drive the processing spindle 42 to move in the vertical direction, so that the processing spindle 42 approaches or moves away from the workpiece mounting mechanism 2 or the tool changing mechanism 3.

[0115] In the embodiment, the vertical driving member 414 controls the movement of the processing spindle 42 in the vertical direction relative to the horizontal plane of the machine base 1 (relative to the tool changing mechanism 3 or relative to the workpiece mounting mechanism 2), so that the processing spindle 42 has three-dimensional movement capability and can flexibly adapt to multi-dimensional processing requirements.

[0116] In the processing process, the vertical driving member 414 can accurately adjust the relative height of the processing spindle 42 and the workpiece surface, meet the requirements of different processes on the processing depth and contact angle, and improve the processing precision. By increasing the movement freedom in the vertical direction, the vertical driving member 414 enables the equipment to process more complex workpiece shapes, such as deep holes, stepped surfaces or multi-layer features.

[0117] The first moving driving member 411 controls the mounting seat 412 to move along the horizontal rail of the gantry 11, and roughly positions the machining spindle 42 to the machining area of the workpiece mounting mechanism 2. The second moving driving member 413 drives the machining spindle 42 to make lateral fine adjustment on the basis of the rough positioning of the first moving driving member 411, so that the machining spindle 42 is aligned with the target machining point of the workpiece.

[0118] Before the machining starts, the vertical driving member 414 controls the machining spindle 42 to move downward to the specified machining depth, and adjusts the height in real time according to the process requirement during the machining. After the machining is completed, the vertical driving member 414 moves the machining spindle 42 upward to the safety height, so as to avoid interference with the mounting seat 412 or the workpiece.

[0119] During the tool changing process, the vertical driving member 414 can make the machining spindle 42 approach or move away from the tool changing mechanism 3, so as to ensure smooth loading and unloading of the tool, realize tool changing, and thus improve the efficiency.

[0120] The first moving driving member 411 drives the mounting seat 412 to move to the position where the tool changing mechanism 3 is located, so that the machining spindle 42 approaches the tool holder 33. The second moving driving member 413 adjusts the machining spindle 42 laterally to align with the target tool holder 33, so as to prepare for the subsequent tool loading and unloading action. The vertical driving member 414 drives the machining spindle 42 to move downward, and precisely connects with the tool head on the tool holder 33.

[0121] In some embodiments, a plurality of vertical driving members 414 can be arranged, and each vertical driving member 414 is separately connected with a machining spindle 42, so as to realize separate control of the lifting of different machining spindles 42.

[0122] In summary, the introduction of the vertical driving member 414 and the cooperation of the first moving driving member 411 and the second moving driving member 413 bring high flexibility and adaptability to the device, and significantly improve the performance and efficiency in the machining and tool changing operations.

[0123] In some embodiments, the first moving driving member 411, the second moving driving member 413 and the vertical driving member 414 can be driving elements such as motors and driving cylinders, which are only exemplarily described herein, but are not limited.

[0124] Referring to Figure 1 and Figure 5 In some embodiments, the workpiece mounting mechanism 2 proposed in the embodiments of the utility model comprises:

[0125] The swing driving member 21 is arranged in one of the two side plates 111.

[0126] The swing arm 22 is rotatably connected to the output end of the swing driving member 21 at one end, and is rotatably connected to the other one of the two side plates 111 at the other end.

[0127] At least one workpiece mounting member 23 is arranged on the swing arm 22 for mounting a workpiece;

[0128] The swing driving member 21 drives the swing arm 22 to swing, and drives the workpiece to swing relative to the machining spindle 42, so that the machining spindle 42 can machine the workpiece within a range of angles.

[0129] In this embodiment, the swing driving member 21 is mounted on one of the two side plates 111 of the gantry 11, and the output end thereof can extend into the space between the two side plates 111 and is connected to one end of the swing arm 22, and is responsible for providing power to drive the swing arm 22 to swing. The other end of the swing arm 22 is rotatably connected to the other one of the two side plates 111, so as to form a swingable support structure.

[0130] The workpiece mounting member 23 is mounted on the swing arm 22, and is used for stably mounting the workpiece and ensuring the stability of the position of the workpiece during machining.

[0131] The swing driving member 21 drives the swing arm 22 to swing along the fulcrum thereof, and the mounted workpiece also changes its position relative to the machining spindle 42 within a range of angles. This swing enables the machining spindle 42 to machine multiple angles, surfaces or parts of the workpiece without multiple clamping.

[0132] When the swing driving member 21 is in the initial position, the position of the workpiece is aligned with the machining point of the machining spindle 42.

[0133] The swing driving member 21 is started according to machining requirements, drives the swing arm 22 to swing, and adjusts the target machining surface of the workpiece to the working range of the machining spindle 42. This process can accurately control the swing angle of the swing arm 22, and ensures the butt joint of the machining spindle 42 and the machining surface of the workpiece.

[0134] After the machining spindle 42 completes machining of the current machining surface, the swing driving member 21 is started again to drive the swing arm 22 to swing, so as to adjust the workpiece on the swing arm 22 to a new angle or position. In this process, the workpiece does not need to be re-clamped, and the movement of the swing arm 22 realizes the continuity of multi-angle or multi-surface machining of the workpiece.

[0135] After the machining task is completed, the swing driving member 21 restores the swing arm 22 to the initial position, and the workpiece is ready to be unloaded.

[0136] The workpiece mounting member 23 can automatically drive the workpiece to be mounted through a pneumatic element or an electrical driving member, or can manually install the workpiece by hand, which is not limited herein.

[0137] In some embodiments, the workpiece mounting member 23 is rotatably connected to the swing arm 22, and an electrical driving member can be used to drive the workpiece mounting member 23 to rotate relative to the swing arm 22, so that the device can adapt to different machining modes, which is only illustrative herein.

[0138] The workpiece mounting mechanism 2 with the above structure achieves the following effects:

[0139] Firstly, the swing function of the swing arm 22 allows the machining spindle 42 to process multiple angles or surfaces of the workpiece without the need for multiple adjustments of the workpiece clamping, significantly improving the processing efficiency. Moreover, it can process complex curved surfaces, special-shaped parts or multi-surface parts, and is particularly suitable for high-requirement precision machining scenarios.

[0140] Secondly, the swing of the swing arm 22 is precisely controlled by the numerical control system, ensuring that the adjustment angle of the workpiece position meets the processing requirements and reducing positioning errors caused by multiple clamping. One clamping can complete the multi-angle and multi-surface processing of the workpiece, reducing the time for repositioning and installing the workpiece and improving the overall processing efficiency of the equipment.

[0141] In summary, the workpiece mounting mechanism 2 proposed in the embodiment achieves the multi-angle swing function of the workpiece through the swing driving member 21 driving the swing arm 22, and can flexibly process multiple surfaces of the workpiece in cooperation with the machining spindle 42.

[0142] In some embodiments, the swing driving member 21 can be a motor, a driving cylinder or other driving elements, which are only exemplary and not limiting.

The recycling mechanism 5 centrally manages the waste through separation and conveying, preventing it from scattering into the equipment or the machining environment.

[0153] In the tool changing stage, the third moving driving member 6 drives the tool changing mechanism 3 to move to a suitable position for docking with the machining spindle 42. In the machining of complex workpieces, the third moving driving member 6 can dynamically adjust the position of the tool changing mechanism 3 according to the machining program, so that the tools on the mounting plate 32 avoid the machining area, that is, after the tool changing is completed, the third moving driving member 6 moves the tool changing mechanism 3 to a safe position to avoid interference with the unloading or cleaning operation.

[0154] In some embodiments, the first sliding structure 12 can be a sliding table, and the second sliding structure 13 can be a component provided with a sliding rail on the adapter plate, which is only illustrative.
