Detailed Implementation

[0031] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand this utility model and implement it. However, the embodiments are not intended to limit this utility model. In this embodiment, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this utility model.

[0032] It should be noted that when one element is considered to be "connected" to another element, it can be directly connected to and integrated with the other element, or there may be an intervening element present. The terms "mounted," "one end," "the other end," and similar expressions used in this invention are for illustrative purposes only.

[0033] In this field, metal additive and subtractive manufacturing integrated equipment is a new type of processing equipment that combines additive manufacturing and subtractive manufacturing technologies. The equipment typically uses electric arc, laser, plasma, electron beam, etc. as heat sources to melt metal materials such as wire or powder and stack them layer by layer according to a preset three-dimensional model to achieve additive manufacturing of metal parts. At the same time, it uses cutting tools equipped with robots or machine tools to perform turning and milling operations to complete subtractive manufacturing, thereby improving the dimensional accuracy and surface quality of the parts. However, current equipment has problems such as large machine tool size, large footprint, and low integration. This utility model embodiment optimizes the structure and integration of each module of the equipment to design an equipment with the functions of existing equipment but with a small footprint and high integration.

[0034] Please refer to Figures 1-3 This utility model provides a five-axis linkage composite additive and subtractive material processing device 1, which includes a base 10, an X-axis motion component 20, a Y-axis motion component 30, a Z-axis motion component 40 and a slide platform 50. The slide platform 50 is provided with a laser cladding component 501 and a cutting component 502.

[0035] One side of the base 10 extends upward to form a support platform 101. The X-axis motion component 20 is mounted on the support platform 101, and the Y-axis motion component 30 is movably connected to the slide platform 50. The slide platform 50 and the Y-axis motion component 30 are both connected to the X-axis motion component 20. The slide platform 50 and the Y-axis motion component 30 can reciprocate along the X-axis direction, while the slide platform 50 reciprocates along the Y-axis direction. It can be understood that the side with the laser cladding component 501 and the cutting component 502 is the processing end, while the support platform 101 is located at the other end opposite to the processing end. The support platform 101 can be integrally constructed with the base 10, or it can be a separate structure that is then fixedly connected to the base 10. The base 10 and the support platform 101 can be configured as structures with internal cavities for placing other components and arranging wiring and control systems, etc.

[0036] The Z-axis motion assembly 40 is connected to the Y-axis motion assembly 30 and is used to drive the laser cladding assembly 501 and the cutting assembly 502 to reciprocate along the Z-axis direction. Understandably, a machine tool drag chain is provided on the Y-axis motion assembly 30 to limit the Y-axis travel when moving along the X-axis direction, and to provide wiring space for the processing device 1 to provide electrical connection for each component.

[0037] The laser cladding assembly 501 and the cutting assembly 502 are positioned on the side opposite to the support platform 101. A five-axis cradle platform 60 extends outward from the side of the support platform 101 facing the laser cladding assembly 501 and the cutting assembly 502. The five-axis cradle platform 60 is used to place the workpiece and provides B-axis and C-axis rotation. The lower ends of the laser cladding assembly 501 and the cutting assembly 502 correspond to the five-axis cradle platform 60. It can be understood that B-axis rotation means the five-axis cradle platform 60 can rotate or pitch around the Y-axis, and C-axis rotation means the five-axis cradle platform 60 can rotate around the Z-axis. Combined with the X-axis motion assembly 20, Y-axis motion assembly 30, and Z-axis motion assembly 40 of the processing device 1, five-axis linkage can be achieved during processing, eliminating the need for a separate rotary table and achieving higher integration.

[0038] Please refer to Figures 1-3 In this embodiment, the X-axis motion assembly 20 includes an X-axis guide rail 201 and a first drive assembly. The first drive assembly 203 may include a first drive screw 202 and a linear motor. The X-axis guide rail 201 is arranged on the upper part of the support platform 101.

[0039] The Y-axis motion assembly 30 includes a Y-axis guide rail 301 and a second drive assembly. The second drive assembly may include a second drive screw and a linear motor. The Y-axis guide rail 301 is arranged on the X-axis guide rail 201 and connected to the first drive assembly 203. The Y-axis motion assembly 30 is connected to the slide platform 50 through the second drive assembly.

[0040] The ram platform 50 is connected to the Y-axis guide rail 301 and to a linear motor via a second drive screw. The second drive assembly drives the Y-axis motion assembly 30 to reciprocate along the Y-axis guide rail 301 on the ram platform 50. Exemplarily, in this embodiment, the X-axis motion assembly 20, Y-axis motion assembly, and Z-axis motion assembly 40 are all driven by linear motors in conjunction with ball screws to achieve linear motion in the X, Y, and Z axes, ensuring high rigidity, high precision, and rapid response in each direction. The guide rail of the Z-axis motion assembly 40 is fixed to the Y-axis motion assembly 30 and reinforced with welded steel plates to support the vertical lifting of the ram platform 50, thus enhancing the rigidity of the device.

[0041] Please refer to Figures 1-3In this embodiment, the five-axis cradle platform 60 includes a connecting part 601 and a platform part 602. The platform part 602 is movably connected to the side of the support platform 101 through the connecting part 601. A fourth drive assembly is provided inside the support platform 101. The platform part 602 is connected to the fourth drive assembly through the connecting part 601. The connecting part 601 can drive the platform part 602 to rotate around the Y-axis. It can be understood that the support platform 101 is provided with a fourth drive assembly that connects to and drives the five-axis cradle platform 60 to rotate. The fourth drive assembly is connected to the connecting part 601 and can drive the connecting part 601 to rotate or pitch around the Y-axis, i.e., rotate the B-axis. The pitch motion mentioned here refers to the swing motion of the five-axis cradle platform 60 around the Y-axis, so as to realize continuous cutting of different inclined surfaces, inclined holes or spatial curved surfaces of the workpiece.

[0042] A rotary platform 603 is located in the middle of the platform section 602. A fifth drive assembly is installed inside the platform section 602. The fifth drive assembly can drive the rotary platform 603 to rotate around the Z-axis. The rotary platform 603 is used to place the workpiece. It can be understood that the workpiece is placed on the rotary platform 603, and the rotary platform 603 drives the workpiece to rotate around the Z-axis, similar to the workpiece rotating on its own axis, thus enabling the workpiece to be processed within a 360° range.

[0043] Please refer to Figures 1-3 In this embodiment, the laser cladding assembly 501 includes a laser cladding head 503, and the cutting assembly 502 includes a cutting head 504. When the processing device 1 drives the laser cladding assembly 501 or the cutting assembly 502 to work, the laser cladding head or the cutting head 504 is located above the rotating platform 603 and faces the rotating platform 603. The laser cladding head 503 or the cutting head 504 performs additive or subtractive processing on the workpiece. It is understood that in the field of integrated metal additive and subtractive processing equipment, some use arc-type DEDs that use a welding arc as a heat source, while others use laser-type DEDs that utilize high-energy-density laser melting as a heat source. This embodiment uses a laser-type DED, which has advantages such as high focusing accuracy, controllable microstructure, and good surface quality. Laser cladding technology is relatively mature in this field, and its specific structure and working principle will not be described in detail here.

[0044] Please refer to Figures 1-3 In this embodiment, a chip collection cover 102 is provided below the corresponding five-axis cradle platform 60 on the base 10. The chip collection cover 102 is recessed downward toward the base 10 to form a chip collection cavity 103. The projection of the chip collection cavity 103 in the Z-axis direction is larger than the projection of the five-axis cradle platform 60, so as to collect the chips that fall off during the processing. It can be understood that the size of the chip collection cover 102 is larger than the size of the five-axis cradle platform 60, so that the chips that fall off during the processing can fall into the chip collection cover 102 and will not fall into other areas of the device and affect the normal operation of the device.

[0045] Please refer to Figures 1-3 In this embodiment, the chip collection cavity 103 is in the shape of a downwardly extending funnel. A chip collection hole 104 is provided at the bottom of the chip collection cavity 103. A powder receiving box 105 is also provided in the base 10. A chip collection tube is provided below the chip collection hole 104. The chip collection tube connects the chip collection hole 104 and the powder receiving box 105 to collect the chips falling from the chip collection hole 104.

[0046] Please refer to Figures 1-3 In this embodiment, a tool magazine platform 106 is also provided on the side of the five-axis cradle platform 60 on the support platform 101. The tool magazine platform 106 includes a subtractive cutting tool magazine 107 and a cladding head tool magazine 108. The subtractive cutting tool magazine 107 is located close to the support platform 101 and can extend or retract along the Y-axis direction. The cladding head tool magazine 108 is located outside the subtractive cutting tool magazine 107. The subtractive cutting tool magazine 107 is used to place the cutting tool head 504, and the cladding head tool magazine 108 is used to place the cladding head. It can be understood that the subtractive cutting tool... The movement of the subtractive tool magazine 107 along the Y-axis and the movement of the slide platform 50 along the Y-axis are two independent motion controls. When the cutting assembly 502 needs to be replaced with a tool head, the subtractive tool magazine 107 extends out. The tool magazine contains tool heads of different sizes. Furthermore, the support platform 101 has a cavity inside to accommodate the subtractive tool magazine 107. When the subtractive tool magazine 107 retracts, it is stored inside the support platform 101. The cladding head tool magazine is used for the pre-replacement and storage of laser cladding heads.

[0047] An automatic tool setter is also installed on the tool magazine platform 106. When the cutting assembly 502 replaces the cutting head 504, the automatic tool setter measures the tool length and performs diameter compensation. Understandably, the automatic tool setter can automatically measure tool parameters and perform tool compensation, avoiding rotary axis tool setting errors during five-axis machining and can cooperate with spindle positioning to automatically update compensation values ​​during non-cutting periods, ensuring part consistency. Automatic tool setters are a relatively mature technology in this field, and their specific structure will not be described in detail here.

[0048] Please refer to Figures 1-3 In this embodiment, the processing device 1 is also equipped with a dustproof baffle 109, which is located on the side of the cladding head magazine 108 near the five-axis cradle platform 60, and is used to shield the cladding head magazine 108. It is understood that the laser cladding assembly 501 is used for additive manufacturing, and the cutting assembly 502 is used for subtractive manufacturing. To avoid interference between these two components, during subtractive manufacturing, the laser cladding head 503 is placed in the cladding head magazine 108, and the dustproof baffle 109 can prevent debris or dust from damaging the laser cladding head 503 during the subtractive cutting process.

[0049] Please refer to Figures 1-3In this embodiment, a quick-connect interface is provided on the side of the slide platform 50. The laser cladding assembly 501 is connected to the processing device 1 through the quick-connect interface to switch the laser cladding assembly 501 to process the workpiece. It can be understood that during subtractive processing, the laser cladding head 503 is placed in the cladding head magazine 108, while during additive processing, the laser cladding head 503 is connected to the processing device 1 through the quick-connect interface, enabling quick replacement and convenient operation.

[0050] Please refer to Figures 1-3 In this embodiment, the processing device 1 is also equipped with an atmosphere printing shield, which covers the processing area of ​​the processing device to form a sealed chamber, used to create a protective atmosphere through protective gas during processing. During additive manufacturing, it is necessary to introduce protective gas into the processing environment to prevent oxygen from causing oxidation at the processing site, thereby improving processing accuracy and quality.

[0051] In this embodiment, the rear end of the base 10 is also provided with a bracket assembly fixedly connected to the base 10, for placing and fixing electrical cabinet components such as transformer boxes. Furthermore, the processing device 1 in this embodiment is also provided with modules such as a powder or wire feeding system, a CNC system and operation panel, an inert gas protection system, and a monitoring system. However, these modules are not the main inventive points of this embodiment, and therefore will not be described in detail in this application. For specific operation and structure, please refer to relevant published patents in the field.

[0052] This embodiment of the invention aims to optimize the body structure of the X-axis motion assembly 20, Y-axis motion assembly 30, and Z-axis motion assembly 40, eliminating the need for large crossbeams and columns for load-bearing support. Furthermore, it integrates B-axis and C-axis motion onto the five-axis cradle platform 60, resulting in a smaller footprint for the processing device 1 compared to existing products. The minimum size is 1.8m * 1.3m (≈2.4m). 2 The size of the additive workpiece is approximately half that of the smallest existing product, and the maximum additive workpiece size of the device in this embodiment is 100mm*100mm*100mm, which is suitable for smaller size and finer customized processing needs. The positioning accuracy is 0.01mm and the repeatability is 0.005mm.

[0053] In this specification, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
