Description

Technical Field

[0001] This invention relates to the field of milling and turning technology, specifically to a highly integrated five-axis milling and turning machining center. Background Technology

[0002] Five-axis milling and turning machining centers are core equipment in modern manufacturing for high-precision machining of complex parts. They can complete multiple processes such as turning, milling, drilling, and tapping in a single setup, reducing the number of workpiece clamping and transfer steps, thereby improving machining accuracy and production efficiency. With the increasing demands for part complexity and machining accuracy in industries such as aerospace, automotive manufacturing, and precision mold making, the application scope of five-axis milling and turning machining centers continues to expand. However, existing five-axis milling and turning machining centers still have many shortcomings in practical use. On the one hand, the clamping and moving mechanisms of traditional machining centers are usually separate, with each functional module occupying a large space, resulting in a large overall machine size and footprint. This makes it difficult to achieve a reasonable arrangement of multiple machines in a limited workshop space, limiting further increases in workshop capacity. On the other hand, tool changing in existing machining centers mostly relies on manual operation or semi-automatic tool changing mechanisms, resulting in long tool changing times and low automation levels, which severely restricts the improvement of machining cycle time in multi-process continuous machining scenarios. Furthermore, the lack of an effective collection and recycling mechanism for the cutting fluid and metal shavings generated during the processing means that the uncontrolled flow of cutting fluid not only pollutes the processing environment but also wastes resources and increases subsequent treatment costs. Summary of the Invention

[0003] The purpose of this invention is to provide a highly integrated five-axis turning and milling machining center to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a highly integrated five-axis turning and milling composite machining center, comprising a support box, several legs fixed at the bottom of the support box, a liquid collection assembly inside the support box, and an adjustment assembly fixed at the top of the support box. The adjustment assembly includes a moving motor and a U-shaped plate. The U-shaped plate is fixed at the top of the support box, and two trapezoidal blocks are fixed at the top of the U-shaped plate. Limiting strips are fixed at the top of each trapezoidal block, and a moving plate is slidably mounted on the two limiting strips. An inclined surface is provided on the moving plate, and a moving screw is rotatably mounted between the two trapezoidal blocks. A connecting plate is threaded onto the moving screw, and the connecting plate is fixed below the moving plate. The moving motor is fixed at the end of the support box, and the output shaft of the moving motor is fixedly connected to the moving screw. Two material drop ports are opened on the U-shaped plate, and four splash guards are fixed on the U-shaped plate. All four splash guards are made of transparent acrylic material. A support assembly is provided at the end of the support box, and a moving assembly is provided on the support assembly. A tool changing assembly is provided on the side of the support assembly.

[0005] Using the above structure, the support box serves as the main load-bearing structure of the entire machining center. Several legs are fixed below the support box, contacting the ground to provide stable foundation support for the entire equipment and prevent displacement due to vibration during processing. An adjustment assembly is fixed above the support box to achieve lateral adjustment of the workpiece clamping position. The moving motor is fixed at the end of the support box. When the clamping position needs to be adjusted, the moving motor starts, and its output shaft drives the moving lead screw to rotate. The moving lead screw is positioned between two trapezoidal blocks, which are fixed above the U-shaped plate, providing a fulcrum for the rotation of the moving lead screw. A connecting plate is threaded onto the moving lead screw and fixed below the moving plate. Therefore, when the moving lead screw rotates, the connecting plate undergoes linear displacement along the axial direction of the moving lead screw under the action of the threads. The moving plate is mounted on two limit strips, which are fixed above the two trapezoidal blocks. The limit strips constrain the sliding direction of the moving plate, ensuring that the moving plate can only move linearly in the horizontal direction, preventing displacement. During the movement of the plate, if it deflects or wobbles, the moving plate is equipped with an inclined surface. The inclined surface design guides the moving plate and the trapezoidal block during movement, ensuring the stability of the moving plate. The U-shaped plate is fixed above the support box. The U-shaped plate has two discharge ports, which are located directly below the two liquid collection tanks. The cutting fluid and chips generated during processing fall into the liquid collection tanks below through the discharge ports. Four splash guards are fixed on the U-shaped plate. The four splash guards are all made of transparent acrylic material. The transparent acrylic material allows the operator to observe the clamping and processing status of the workpiece above the U-shaped plate through the splash guards. At the same time, the splash guards enclose the processing area to prevent cutting fluid and chips from splashing outwards. The end of the support box is equipped with a support assembly, on which a moving assembly is installed. The moving assembly is used to realize the multi-directional movement of the tool and the processing head. The side of the support assembly is equipped with a tool changing assembly, which is used to quickly change tools during processing to realize multi-process continuous processing. By setting a moving motor to drive the moving lead screw to rotate, and the moving lead screw engaging with the connecting plate threadedly, the connecting plate drives the moving plate to slide on the second limiting strip, achieving precise lateral adjustment of the workpiece clamping position. The adjustment process is smooth and highly accurate. The second limiting strip constrains the movement direction of the moving plate, ensuring the straightness of the moving plate's movement and avoiding processing errors caused by movement deviations. The inclined surface on the moving plate, in conjunction with the trapezoidal block, plays a guiding and supporting role during movement, further improving the stability of the moving plate's movement. The two discharge ports on the U-shaped plate correspond to the liquid collection tank below. Waste liquid and debris generated during processing slide down the inclined surface onto the U-shaped plate, and then fall directly into the liquid collection tank through the discharge ports, achieving... The system features directional collection of waste liquid, preventing it from flowing freely inside the support box. Four splash guards made of transparent acrylic material ensure both visual monitoring of the processing area by operators and effective enclosure of the processing area, preventing cutting fluid splashes from affecting surrounding equipment and personnel. The transparent acrylic material is also lightweight, corrosion-resistant, and easy to clean, making it suitable for the working environment of machining centers. The support legs provide a stable foundation for the support box, effectively reducing the impact of processing vibration on the overall stability of the equipment. The integrated design of the adjustment, movement, and tool changing components enables the entire machining center to achieve multi-functional integration within a limited space, improving the space utilization and processing efficiency of the equipment.

[0006] Two support seats are fixed on the movable plate. Annular cylinder one and annular cylinder two are fixed above the two support seats respectively. A rotating plate is rotatably arranged between annular cylinder one and annular cylinder two. A rotating motor is fixed below the rotating plate. A clamping plate is fixed on the output shaft of the rotating motor and is rotatably arranged on the rotating plate. A rotating motor is fixed inside annular cylinder one, and the output shaft of the rotating motor is fixedly connected to the rotating plate.

[0007] With the above structure, two support seats are fixed on the moving plate, located on the upper sides of the moving plate respectively, providing a support base for the rotational clamping of the workpiece. Above the two support seats, an annular cylinder one and an annular cylinder two are fixed respectively, coaxially arranged, forming a rotational space between them. A rotating plate is rotatably mounted between annular cylinders one and two, capable of rotating around an axis between them. A rotating motor is fixed below the rotating plate. After the rotating motor starts, its output shaft drives the clamping disc to rotate. The clamping disc is rotatably mounted on the rotating plate, thus the clamping disc... Rotating together with the output shaft of the rotary motor, it realizes the rotation clamping and indexing of the workpiece. The rotary motor is fixed inside the annular cylinder, and the output shaft of the rotary motor is fixedly connected to the rotary plate. When the rotary motor starts, its output shaft drives the rotary plate and the entire clamping mechanism to rotate around the axis of the rotary motor, realizing the workpiece flipping processing. That is, it realizes one of the rotary axis functions of five-axis machining. The C-axis rotation of the workpiece is realized by driving the clamping plate to rotate through the rotary motor, and the A-axis or B-axis rotation of the workpiece is realized by driving the rotary plate to flip through the rotary motor. The two work together to realize the multi-axis linkage required for five-axis milling and turning composite machining. By setting two support seats on the moving plate and fixing annular cylinder one and annular cylinder two on the support seats, and rotating a plate between annular cylinder one and annular cylinder two, a stable rotary clamping structure is constructed. The rotating plate rotates smoothly under the constraint of annular cylinder one and annular cylinder two, with strong load-bearing capacity. The rotary motor drives the clamping plate to rotate, realizing the rotation of the workpiece in the C-axis direction. This allows the workpiece to be indexed and positioned at any angle during turning and milling, meeting the needs of multi-angle machining of workpieces in five-axis machining. The rotary motor fixed inside annular cylinder one has its output shaft fixedly connected to the rotating plate. The rotary motor drives the rotating plate to flip, realizing the rotation of the workpiece in the A-axis or B-axis direction. Together with the C-axis rotation of the clamping plate, they form the rotary axis system of five-axis linkage machining. The support seats provide a stable mounting base for annular cylinder one and annular cylinder two, ensuring the stability of the rotary mechanism when rotating at high speed. The entire rotary clamping mechanism is integrated on the rotating plate and is adjusted laterally along with the moving plate, realizing the coordinated control of clamping position and rotary machining, and improving the functional integration of the machining center.

[0008] The support assembly includes two support columns, both of which are fixed above the support box, and a mounting bracket is fixed above the two support columns.

[0009] Using the above structure, the support assembly consists of two support columns and a mounting frame. The two support columns are fixed above the support box and are vertically arranged to provide vertical support for the mounting frame above. The mounting frame is fixed above the two support columns and spans between the two support columns to form a stable frame structure. The mounting frame serves as the mounting carrier for the moving assembly. Components such as the transverse motor, transverse lead screw, and limit bar in the moving assembly are all mounted on the mounting frame. The support columns raise the mounting frame to a certain height, so that there is enough space below the mounting frame for installing components such as the moving frame and equipment frame. At the same time, the rigid structure of the support columns ensures that the mounting frame will not deform when subjected to processing loads. Two support columns are fixed above the support box, providing reliable vertical support for the mounting frame. The support columns are fixed with a rigid connection, which can withstand large cutting forces during processing without deformation, ensuring the installation accuracy of the moving component. The mounting frame is fixed above the two support columns, forming a transverse frame structure. This structure has high bending and torsional stiffness, providing a stable installation platform for the moving component. The support columns raise the mounting frame, giving the moving component and processing head sufficient operating space and avoiding interference with the adjustment components inside the support box. The two support columns are symmetrically arranged, ensuring even stress distribution on the mounting frame and improving the structural stability and service life of the entire support assembly.

[0010] The moving assembly includes a transverse motor, a transverse lead screw, and two limit bars. Both limit bars are fixed to the side of the mounting frame, and a moving frame is slidably mounted on the two limit bars. The transverse lead screw is rotatably mounted on the side of the mounting frame via a bearing seat. The transverse lead screw and the mounting frame are threadedly connected. The transverse motor is fixed to the side of the mounting frame, and the output shaft of the transverse motor is fixedly connected to the transverse lead screw.

[0011] Using the above structure, the moving component is used to realize the positional movement of the processing head in the lateral direction. The lateral motor is fixed to the side of the mounting frame. After the lateral motor is started, its output shaft drives the lateral lead screw to rotate. The lateral lead screw is rotatably mounted on the side of the mounting frame through a bearing seat. The lateral lead screw and the mounting frame are connected by a thread. Therefore, when the lateral lead screw rotates, due to the constraint of the thread, the lateral lead screw itself generates axial displacement. The lateral lead screw is connected to the moving frame, which is mounted on two limit bars. Both limit bars are fixed to the side of the mounting frame. The limit bars constrain the movement direction of the moving frame, so that the moving frame can only move linearly along the axial direction of the lateral lead screw. Therefore, the lateral motor drives the lateral lead screw to rotate, and the lateral lead screw drives the moving frame to slide on the limit bars through the threaded transmission, thereby realizing the lateral position adjustment of the processing head. The transverse motor drives the transverse lead screw to rotate, which is threadedly connected to the mounting bracket. Utilizing the lead screw and nut transmission principle, rotational motion is converted into linear motion, resulting in high transmission accuracy and good self-locking. After the drive stops, the moving bracket will not shift due to cutting force. Two limit strips are fixed to the side of the mounting bracket, providing double constraint on the direction of movement of the moving bracket, effectively preventing deflection or swaying during movement and ensuring the straightness and repeatability of the moving bracket's movement. The transverse motor is fixed to the side of the mounting bracket, resulting in a compact layout that reduces the space occupied by the moving components and improves the integration of the equipment. Compared to gear and rack transmission, the lead screw transmission method offers higher positioning accuracy and lower noise, making it suitable for high-precision milling and turning machining applications.

[0012] Two limiting strips are fixed on the top of the mobile frame. Equipment racks are slidably mounted on the two limiting strips. An electric push rod is fixed on the mobile frame. The end of the electric push rod is fixed on the equipment rack. Spray heads are provided on the side of the equipment rack. Fixed rods are fixed on both sides of the equipment rack. Air curtain boxes are fixed on the two fixed rods. The air curtain boxes are annular and are connected to an external air supply device through a hose.

[0013] With the above structure, two limiting bars are fixed above the moving frame, and an equipment frame is slidably mounted on the two limiting bars. The equipment frame can slide up and down along the direction of the limiting bars. An electric push rod is fixed on the moving frame, and the end of the electric push rod is fixed on the equipment frame. When the electric push rod extends or retracts, it drives the equipment frame to slide up and down on the limiting bars, thereby adjusting the position of the machining head in the Z-axis direction, i.e., controlling the machining depth. Spray heads are provided on the side of the equipment frame. The spray heads are used to spray cutting fluid into the machining area during the machining process to cool and lubricate the tool and workpiece. Fixed rods are fixed on both sides of the equipment frame, and air curtain boxes are fixed on the two fixed rods. The air curtain boxes are annular structures, and the annular air curtain boxes surround the outer perimeter of the machining area. The air curtain boxes are connected to an external air supply device through a hose. The external air supply device delivers high-pressure gas into the air curtain boxes. The gas is sprayed out from the annular outlet of the air curtain boxes to form an annular air curtain, which isolates the machining area from the outside world and prevents cutting fluid and chips from spreading outward. The electric push rod drives the equipment frame to slide on the limit bar three, achieving precise position adjustment of the machining head in the Z-axis direction. The electric push rod one features fast response speed and high positioning accuracy, meeting the precise control requirements for machining depth in milling and turning machining. The two limit bars three constrain the movement direction of the equipment frame, ensuring the straightness and stability of the equipment frame's up and down movement. The spray head is located on the side of the equipment frame, continuously spraying cutting fluid into the machining area during the machining process, effectively reducing the temperature of the tool and workpiece, reducing tool wear, and improving the surface quality of the machined surface. The air curtain box has a ring structure and is connected to an external air supply device through a hose. The formed ring air curtain can surround the machining area, effectively preventing cutting fluid splashing and chip diffusion, keeping the machining environment clean. The fixing rod fixes the air curtain box to both sides of the equipment frame, so that the air curtain box moves with the equipment frame, ensuring that the air curtain box always surrounds the perimeter of the machining area, improving the isolation effect of the air curtain.

[0014] The tool changing assembly includes a connecting frame, which is fixed to the side of one of the support columns. A side box is fixed to one side of the connecting frame, and a switching motor is fixed above the side box. An electric push rod is connected to the output shaft of the switching motor, and a tool changing rod is connected to the end of the electric push rod. A mounting box is provided on the side box, and a side tool magazine is fixed to the other side of the connecting frame. Several tools are installed inside the side tool magazine, and an annular baffle is fixed on the side tool magazine.

[0015] With the above structure, the tool changing assembly is fixed to the side of one of the support columns via a connecting frame. The connecting frame serves as the mounting carrier for the various components of the tool changing assembly. A side box is fixed to one side of the connecting frame, and a switching motor is fixed above the side box. After the switching motor starts, its output shaft drives the electric push rod two to move. The end of the electric push rod two is connected to the tool changing rod. The tool changing rod extends or retracts under the drive of the electric push rod two to realize the grabbing and release of the tool. An installation box is provided on the side box, which is used to temporarily store the tool during the tool changing process. A side tool magazine is fixed to the other side of the connecting frame. The side tool magazine contains several tools, which are arranged and stored in the side tool magazine according to the order of the machining process. When it is necessary to change the tool, the switching motor drives the electric push rod two to move the tool changing rod to the side tool magazine. The tool changing rod grabs the required tool, and then the switching motor drives in the opposite direction, and the tool changing rod sends the tool to the installation box or directly installs it on the machining head to complete the tool changing operation. An annular baffle is fixed on the side tool magazine, which surrounds the opening of the side tool magazine. By switching the motor to drive the electric push rod two to move the tool changer, the automatic tool grabbing and release is realized. The tool changing process is highly automated, reducing manual intervention and improving tool changing efficiency. The side-mounted tool magazine is fixed on the connecting frame and has several tools inside. It can store tools required for various machining processes, meeting the needs of continuous multi-process machining. The mounting box is set on the side box and provides a temporary storage position for tools during tool changing, avoiding the tool changer from moving without load during tool exchange and improving the continuity of tool changing actions. The annular baffle is fixed on the side tool magazine to physically shield the tools and prevent them from falling accidentally, improving the safety of the equipment. The tool changing assembly is fixed on the side of the support column, close to the machining area, shortening the movement stroke of the tool changer and reducing the time required for tool changing. The connecting frame integrates the side box and the side tool magazine together, with a compact structure, small footprint, and improved equipment integration.

[0016] The liquid collection assembly includes a pull-out box, which is slidably installed inside the support box. The pull-out box has four mesh partitions inside, which divide the interior of the pull-out box into a liquid storage chamber and two liquid collection chambers. A filter box is installed between the two mesh partitions on the same side. The two discharge ports are located below the corresponding liquid collection chambers. A submersible pump is fixed inside the liquid storage chamber. The outlet of the submersible pump is connected to a hose, and the end of the hose is connected to the spray head.

[0017] Using the above structure, the fluid collection assembly is used to collect and recycle the cutting fluid generated during processing. The pull-out box is slidably installed inside the support box and can be pulled out for easy cleaning and replacement of the internal filter box. The pull-out box has four mesh partitions that divide its interior into one storage tank and two collection tanks. Two discharge ports are located directly below the corresponding collection tanks. During processing, the cutting fluid and debris falling from the U-shaped plate through the discharge ports fall into the two collection tanks respectively. The mesh partitions have a filtering function, allowing the cutting fluid to... The cutting fluid flows through the mesh baffle into the collection tank below, while larger metal chips and impurities are intercepted by the mesh baffle above. A filter box is installed between the two mesh baffles on the same side. The filter box performs secondary fine filtration on the cutting fluid falling into the collection tank to remove fine particles and impurities from the cutting fluid. The filtered clean cutting fluid is collected in the storage tank. A submersible pump is fixed inside the storage tank. After the submersible pump is started, the clean cutting fluid in the storage tank is drawn out through a hose. The end of the hose is connected to a spray head. The clean cutting fluid is sprayed into the machining area through the spray head to realize the recycling of the cutting fluid. By installing a pull-out box inside the support box, operators can easily pull it out to clean and maintain the internal filter box and mesh baffles, improving the maintainability of the equipment. Four mesh baffles divide the pull-out box into a storage tank and two collection tanks, enabling graded collection of cutting fluid. The two collection tanks correspond to two discharge ports, allowing waste fluid from different processing areas to be collected separately for easier subsequent processing. The mesh baffles perform preliminary filtration of the cutting fluid, intercepting large particles of debris, while the filter box performs secondary fine filtration. This dual filtration mechanism effectively removes impurities from the cutting fluid, ensuring the cleanliness of the circulating cutting fluid and improving the quality of the machined surface. The submersible pump in the storage tank delivers the filtered clean cutting fluid to the spray head through a hose, achieving closed-loop recycling of the cutting fluid, reducing cutting fluid consumption, lowering processing costs, and reducing waste discharge, meeting the requirements of green processing. The pull-out design of the box makes filter box replacement and cleaning simple and quick, reducing equipment downtime for maintenance.

[0018] Compared with the prior art, the beneficial effects of the present invention are: The moving plate is precisely adjusted laterally by a moving motor-driven lead screw in conjunction with limit bar two. The inclined surface on the trapezoidal block ensures stable adjustment and avoids machining errors caused by motion deviation. A rotary motor drives the moving plate to flip, and a rotating motor drives the clamping plate to rotate, achieving multi-axis linkage to meet the needs of five-axis milling and turning composite machining. The support column provides high-rigidity support for the mounting frame. The transverse motor drives the transverse lead screw in conjunction with limit bar one to achieve high-precision transverse movement of the moving frame. The lead screw's self-locking property ensures no displacement after the drive stops. Electric push rod one, in conjunction with limit bar three, enables precise positioning of the equipment frame in the Z-axis direction. The combination of the spray head and the annular air curtain box achieves cooling, lubrication, and splash isolation. The tool changing assembly uses a switching motor-driven tool changing lever in conjunction with a side-mounted tool magazine to achieve rapid and automatic tool changing. The annular baffle improves storage safety. The mesh partition and filter box inside the pull-out box form a dual filtration mechanism. The submersible pump enables closed-loop recycling of cutting fluid. All components are highly integrated on the support box, with a partitioned layout that does not interfere with each other, improving space utilization, machining efficiency, and service life.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figures 1-9As shown, the present invention provides a technical solution: a highly integrated five-axis turning and milling composite machining center, including a support box 5, several support legs 28 fixed at the bottom of the support box 5, a liquid collection assembly inside the support box 5, and an adjustment assembly fixed at the top of the support box 5. The adjustment assembly includes a moving motor 15 and a U-shaped plate 33, the U-shaped plate 33 being fixed above the support box 5, and two trapezoidal blocks 20 fixed above the U-shaped plate 33. Limiting strips 21 are fixed above each of the two trapezoidal blocks 20, and a moving plate 22 is slidably mounted on the two limiting strips 21. The moving plate 22 is provided with... A movable lead screw 27 is rotatably mounted between two trapezoidal blocks 20 on the inclined plane. A connecting plate is threaded onto the movable lead screw 27 and fixed below the movable plate 22. A movable motor 15 is fixed at the end of the support box 5, and the output shaft of the movable motor 15 is fixedly connected to the movable lead screw 27. Two material discharge ports 35 are opened on the U-shaped plate 33, and four anti-splash baffles 6 are fixed on the U-shaped plate 33. All four anti-splash baffles 6 are made of transparent acrylic material. A support assembly is provided at the end of the support box 5, and a movable assembly is provided on the support assembly. A tool changing assembly is provided on the side of the support assembly.

[0023] The support box 5 serves as the main load-bearing structure of the entire machining center. Several support legs 28 are fixed below the support box 5, and the support legs 28 are in contact with the ground, providing stable foundation support for the entire equipment and preventing displacement due to vibration during processing. An adjustment assembly is fixed on the top of the support box 5, which is used to adjust the workpiece clamping position laterally. The moving motor 15 is fixed at the end of the support box 5. When the clamping position needs to be adjusted, the moving motor 15 is started, and its output shaft drives the moving lead screw 27 to rotate. The moving lead screw 27 is rotatably positioned between two trapezoidal blocks 20. Two trapezoidal blocks 20 are fixed above the U-shaped plate 33, providing a fulcrum for the rotation of the movable lead screw 27. A connecting plate is threaded onto the movable lead screw 27, and the connecting plate is fixed below the movable plate 22. Therefore, when the movable lead screw 27 rotates, the connecting plate undergoes linear displacement along the axial direction of the movable lead screw 27 under the action of the threads. The movable plate 22 is mounted on two limiting strips 21, which are fixed above the two trapezoidal blocks 20. The limiting strips 21 constrain the sliding direction of the movable plate 22, ensuring that the movable plate 22 can only move linearly in the horizontal direction, avoiding... To prevent the moving plate 22 from deflecting or wobbling during movement, the moving plate 22 is equipped with an inclined surface. This inclined surface guides the moving plate 22 against the trapezoidal block 20, ensuring the stability of the moving plate 22's movement. The U-shaped plate 33 is fixed above the support box 5. Two discharge ports 35 are provided on the U-shaped plate 33, located directly below the two liquid collection chambers. Cutting fluid and debris generated during processing fall into the liquid collection chambers below through the discharge ports 35. Four splash guards 6 are fixed on the U-shaped plate 33. All baffles 6 are made of transparent acrylic material. The transparent acrylic material allows the operator to observe the clamping and processing status of the workpiece above the U-shaped plate 33 through the splash baffles 6. At the same time, the splash baffles 6 enclose the processing area to prevent cutting fluid and chips from splashing outward. The end of the support box 5 is provided with a support assembly, and a moving assembly is provided on the support assembly. The moving assembly is used to realize the multi-directional movement of the tool 16 and the processing head. The side of the support assembly is provided with a tool changing assembly, which is used to quickly change the tool 16 during the processing to realize multi-process continuous processing. By setting a moving motor 15 to drive the moving lead screw 27 to rotate, the moving lead screw 27 is threadedly engaged with the connecting plate, and the connecting plate drives the moving plate 22 to slide on the limiting strip 21, achieving precise lateral adjustment of the workpiece clamping position. The adjustment process is smooth and highly accurate. The limiting strip 21 constrains the movement direction of the moving plate 22, ensuring the straightness of the movement of the moving plate 22 and avoiding processing errors caused by movement deviation. The inclined surface set on the moving plate 22 cooperates with the trapezoidal block 20, which plays a guiding and supporting role during the movement, further improving the stability of the movement of the moving plate 22. The two discharge ports 35 opened on the U-shaped plate 33 correspond to the liquid collection tank below, and the waste liquid and debris generated during the processing can fall directly into the collection tank through the discharge ports 35. In the liquid tank, waste liquid is collected in a specific direction, preventing it from flowing freely inside the support box 5. The four splash guards 6 are made of transparent acrylic material, which not only ensures the operator's visual monitoring of the processing area, but also effectively encloses the processing area to prevent cutting fluid splashing from affecting surrounding equipment and personnel. The transparent acrylic material is also lightweight, corrosion-resistant, and easy to clean, making it suitable for the working environment of the machining center. The support legs 28 provide a stable foundation for the support box 5, effectively reducing the impact of processing vibration on the overall stability of the equipment. The integrated setting of the adjustment components, moving components, and tool changing components enables the entire machining center to achieve multi-functional integration within a limited space, improving the space utilization and processing efficiency of the equipment.

[0024] Two support seats 19 are fixed on the movable plate 22. An annular cylinder 1 8 and an annular cylinder 2 18 are fixed above the two support seats 19, respectively. A rotating plate 29 is rotatably mounted between the annular cylinders 1 8 and 2 18. A rotary motor is fixed below the rotating plate 29. A clamping disc 23 is fixed on the output shaft of the rotary motor and rotatably mounted on the rotating plate 29. A rotary motor 26 is fixed inside the annular cylinder 1 8, and the output shaft of the rotary motor 26 is fixedly connected to the rotating plate 29. The two support seats 19 are located on the upper sides of the movable plate 22, providing a support base for the rotational clamping of the workpiece. An annular cylinder 1 8 and an annular cylinder 2 18 are fixed above the two support seats 19, respectively. The annular cylinders 1 8 and 2 18 are coaxially arranged, forming a rotational space between them. A rotating plate 29 is rotatably mounted between the annular cylinders 1 8 and 2 18. It can rotate around the axis between the first annular cylinder 8 and the second annular cylinder 18. A rotary motor is fixed below the rotary plate 29. After the rotary motor is started, its output shaft drives the clamping disk 23 to rotate. The clamping disk 23 is rotatably set on the rotary plate 29. Therefore, the clamping disk 23 rotates together with the output shaft of the rotary motor to realize the rotation clamping and indexing of the workpiece. A rotary motor 26 is fixed inside the first annular cylinder 8. The output shaft of the rotary motor 26 is fixedly connected to the moving plate 22. When the rotary motor 26 is started, its output shaft drives the rotary plate 29 and the entire clamping mechanism to rotate around the axis of the rotary motor 26 to realize the flipping processing of the workpiece. That is, it realizes one of the rotary axis functions of five-axis machining. The C-axis rotation of the workpiece is realized by driving the clamping disk 23 to rotate by the rotary motor. The A-axis or B-axis rotation of the workpiece is realized by driving the moving plate 22 to flip by the rotary motor 26. The two work together to realize the multi-axis linkage required for five-axis milling and turning composite machining. By setting two support seats 19 on the moving plate 22, and fixing annular cylinder 1 8 and annular cylinder 2 18 on the support seats 19, and rotating plate 29 rotatably arranged between annular cylinder 1 8 and annular cylinder 2 18, a stable rotary clamping structure is constructed. The rotating plate 29 rotates smoothly under the constraint of annular cylinder 1 8 and annular cylinder 2 18, exhibiting strong load-bearing capacity. The rotating motor drives the clamping disk 23 to rotate, realizing the C-axis rotation of the workpiece. This allows the workpiece to be indexed and positioned at any angle during turning and milling processes, meeting the requirements for multi-angle machining of workpieces in five-axis machining. The annular cylinder 1 8 is internally fixed... The rotary motor 26 has its output shaft fixedly connected to the moving plate 22. The rotary motor 26 drives the moving plate 22 to rotate, realizing the rotation of the workpiece in the A-axis or B-axis direction. Together with the rotation of the clamping plate 23 in the C-axis direction, it forms a five-axis linkage machining rotary axis system. The support base 19 provides a stable mounting foundation for the annular cylinder 1 8 and annular cylinder 2 18, ensuring the stability of the rotary mechanism when rotating at high speed. The entire rotary clamping mechanism is integrated on the moving plate 22 and is adjusted laterally along with the moving plate 22, realizing the coordinated control of the clamping position and rotary machining, and improving the functional integration of the machining center.

[0025] The support assembly includes two support columns 14, both of which are fixed above the support box 5. A mounting frame 13 is fixed above the two support columns 14. The support assembly consists of two support columns 14 and a mounting frame 13. The two support columns 14 are fixed above the support box 5 and are vertically arranged to provide vertical support for the mounting frame 13 above them. The mounting frame 13 spans between the two support columns 14, forming a stable frame structure. The mounting frame 13 serves as the mounting carrier for the moving assembly. Components such as the transverse motor 9, the transverse lead screw 10, and the limit bar 11 in the moving assembly are all mounted on the mounting frame 13. The support columns 14 raise the mounting frame 13 to a certain height, so that there is enough space below the mounting frame 13 for mounting components such as the moving frame 12 and the equipment frame 38. At the same time, the rigid structure of the support columns 14 ensures that the mounting frame 13 will not deform when subjected to processing loads. Two support columns 14 are fixed above the support box 5, providing reliable vertical support for the mounting frame 13. The support columns 14 are fixed by a rigid connection, which can withstand large cutting forces without deformation during processing, ensuring the installation accuracy of the moving component. The mounting frame 13 is fixed above the two support columns 14, forming a transverse frame structure. This structure has high bending stiffness and torsional stiffness, which can provide a stable installation platform for the moving component. The support columns 14 raise the mounting frame 13, so that the moving component and the processing head have sufficient operating space, avoiding interference with the adjustment components inside the support box 5. The two support columns 14 are symmetrically arranged, so that the mounting frame 13 is subjected to uniform force, improving the structural stability and service life of the entire support component.

[0026] The moving assembly includes a transverse motor 9, a transverse lead screw 10, and two limit bars 11. Both limit bars 11 are fixed to the side of the mounting frame 13. A moving frame 12 is slidably mounted on the two limit bars 11. The transverse lead screw 10 is rotatably mounted on the side of the mounting frame 13 via a bearing seat. The transverse lead screw 10 and the mounting frame 13 are threadedly connected. The transverse motor 9 is fixed to the side of the mounting frame 13, and its output shaft is fixedly connected to the transverse lead screw 10. The moving assembly is used to move the processing head in the transverse direction. The transverse motor 9 is fixed to the side of the mounting frame 13. After the transverse motor 9 is started, its output shaft drives the transverse lead screw 10 to rotate. The transverse lead screw 10 is rotatably mounted on the side of the mounting frame 13 via a bearing seat. On the side of the mounting bracket 13, the transverse lead screw 10 is threadedly connected to the mounting bracket 13. Therefore, when the transverse lead screw 10 rotates, due to the constraint of the thread, the transverse lead screw 10 itself generates axial displacement. The transverse lead screw 10 is connected to the movable bracket 12, which is set on two limit bars 11. Both limit bars 11 are fixed to the side of the mounting bracket 13. The limit bars 11 constrain the movement direction of the movable bracket 12, so that the movable bracket 12 can only move linearly along the axial direction of the transverse lead screw 10. Therefore, the transverse motor 9 drives the transverse lead screw 10 to rotate, and the transverse lead screw 10 drives the movable bracket 12 to slide on the limit bars 11 through the threaded transmission, thereby realizing the transverse position adjustment of the processing head. The transverse motor 9 drives the transverse lead screw 10 to rotate. The transverse lead screw 10 is threadedly connected to the mounting bracket 13. The rotational motion is converted into linear motion using the lead screw and nut transmission principle. It has high transmission accuracy and good self-locking performance. After the drive stops, the moving bracket 12 will not be displaced due to cutting force. Two limit strips 11 are fixed to the side of the mounting bracket 13, which double-constrains the movement direction of the moving bracket 12, effectively preventing the moving bracket 12 from deflecting or shaking during movement, and ensuring the straightness and repeatability of the moving bracket 12. The transverse motor 9 is fixed to the side of the mounting bracket 13, which is compact and reduces the space occupied by the moving components, improving the integration of the equipment. Compared with gear and rack transmission, the lead screw transmission method has higher positioning accuracy and lower noise, which is suitable for the needs of high-precision milling and turning composite machining.

When the electric push rod 24 is used, the spray head 37 is provided on the side of the equipment frame 38. Fixing rods 34 are provided on both sides of the equipment frame 38. When the push rod 24 extends or retracts, it drives the equipment frame 38 to slide up and down on the limit bar 25, thereby adjusting the position of the machining head in the Z-axis direction, i.e., controlling the machining depth. The side of the equipment frame 38 is equipped with a spray head 37, which is used to spray cutting fluid into the machining area during the machining process to cool and lubricate the tool 16 and the workpiece. Both sides of the equipment frame 38 are fixed with fixing rods 34, and air curtain boxes 4 are fixed on the two fixing rods 34. The air curtain box 4 has a ring structure and surrounds the outer perimeter of the machining area. The air curtain box 4 is connected to an external air supply device through a hose. The external air supply device delivers high-pressure gas into the air curtain box 4, and the gas is sprayed out from the ring outlet of the air curtain box 4 to form a ring air curtain, which isolates the machining area from the outside and prevents cutting fluid and chips from spreading outward. The electric push rod 24 drives the equipment frame 38 to slide on the limiting strip 25, realizing precise position adjustment of the machining head in the Z-axis direction. The electric push rod 24 has the characteristics of fast response speed and high positioning accuracy, which can meet the precise control requirements of machining depth in milling and turning composite machining. The two limiting strips 25 constrain the movement direction of the equipment frame 38, ensuring the straightness and stability of the vertical movement of the equipment frame 38. The spray head 37 is set on the side of the equipment frame 38, which can continuously spray cutting fluid into the machining area during the machining process, effectively reducing the temperature of the tool 16 and the workpiece, reducing tool 16 wear, and improving the machining surface quality. The air curtain box 4 has a ring structure and is connected to the external air supply device through a hose. The ring air curtain formed can surround the machining area, effectively preventing cutting fluid splashing and chip diffusion, keeping the machining environment clean. The fixing rod 34 fixes the air curtain box 4 to both sides of the equipment frame 38, so that the air curtain box 4 moves with the equipment frame 38, ensuring that the air curtain box 4 always surrounds the periphery of the machining area, improving the isolation effect of the air curtain.

The tool changer 3 sends the tool 16 to the mounting box 2 or directly installs it on the processing head to complete the tool change operation. The side tool magazine 17 is fixed with an annular baffle 1. The annular baffle 1 surrounds the opening of the side tool magazine 17. By switching motor 32 to drive electric push rod 2 to move tool changer 3, automatic tool grabbing and release of tool 16 is achieved. The tool changing process is highly automated, reducing manual intervention and improving tool changing efficiency. Side tool magazine 17 is fixed on connecting frame 39 and contains several tools 16, which can store tools 16 required for various processing operations, meeting the needs of continuous processing of multiple processes. Mounting box 2 is set on side box 30 to provide temporary storage position for tools 16 during tool changing, avoiding tool changer 3 from moving without load during tool 16 exchange, and improving the continuity of tool changing action. Annular baffle 1 is fixed on side tool magazine 17 to physically shield tools 16, preventing tools 16 from falling accidentally and improving equipment safety. The tool changing assembly is fixed to the side of support column 14, close to the processing area, shortening the movement stroke of tool changer 3 and reducing the time required for tool changing.

The pull-out box 7 is slidably disposed inside the support box 5 and can be pulled out of the support box 5 for easy cleaning and replacement of the internal filter box 36. The pull-out box 7 has four mesh partitions 31 inside, dividing the interior into one storage chamber and two collection chambers. Both discharge ports 35 are located directly below the corresponding liquid collection tanks. During the processing, the cutting fluid and chips falling from the U-shaped plate 33 fall into the two liquid collection tanks through the discharge ports 35. The mesh baffle 31 has a filtering function.

A filter box 36 is set between the two mesh baffles 31 on the same side. The filter box 36 performs secondary fine filtration on the cutting fluid falling into the liquid collection tank to remove fine particles and impurities in the cutting fluid.

[0030] Working principle: During operation, several support legs 28 provide a stable foundation for the support box 5. The entire machining center supports various functional components through the support box 5. First, when the workpiece clamping position needs to be adjusted laterally, the moving motor 15 starts, and its output shaft drives the moving lead screw 27 to rotate between the two trapezoidal blocks 20. The moving lead screw 27 is threadedly engaged with the connecting plate, which is fixed below the moving plate 22. Therefore, the moving plate 22 slides linearly in the horizontal direction on the two limit bars 21. The inclined surface on the moving plate 22 cooperates with the trapezoidal blocks 20 to achieve guidance. After the moving plate 22 reaches the designated position, the two... The rotating plate 29 between the first annular cylinder 8 and the second annular cylinder 18 on the support base 19 drives the clamping disk 23 to rotate under the drive of the rotating motor, realizing the C-axis rotation clamping of the workpiece. At the same time, the rotating motor 26 inside the first annular cylinder 8 starts, and its output shaft drives the rotating plate 29 and the entire clamping mechanism to rotate, realizing the A-axis or B-axis rotation of the workpiece, completing the multi-axis positioning of the workpiece. Subsequently, the two support columns 14 in the support assembly raise the mounting frame 13 to the processing height, and the transverse motor 9 starts to drive the transverse lead screw 10 to rotate. The transverse lead screw 10 is threadedly connected to the mounting frame 13, and the moving frame 12 moves between two limits. The horizontal sliding of the positioning bar 11 and the telescopic extension of the electric push rod 24 on the moving frame 12 drive the equipment frame 38 to slide up and down on the two limiting bars 25, achieving precise positioning of the machining head in the X and Z axes. The spray head 37 on the side of the equipment frame 38, driven by the submersible pump, sprays clean cutting fluid from the storage tank, which has been filtered by the mesh partition 31 and the filter box 36, into the machining area through a hose. At the same time, the annular air curtain box 4 on the fixed rods 34 on both sides of the equipment frame 38 sprays annular air curtains through the external air supply device to isolate the machining area. The cutting fluid and debris generated during the machining process pass through the U-shaped plate 3. The two discharge ports 35 on the cutting fluid 3 drop into the two collection chambers inside the pull-out box 7. After preliminary filtration by the mesh partition 31, the fluid is filtered a second time by the filter box 36 and flows into the storage chamber, completing the closed-loop circulation of the cutting fluid. When it is necessary to change the cutting tool 16, the switching motor 32 drives the electric push rod 2 to move the tool changer 3 to the side tool magazine 17 to grab the required cutting tool 16. After being transferred through the mounting box 2, the cutting tool 16 is installed on the machining head. The annular baffle 1 surrounds the side tool magazine 17 to prevent the cutting tool 16 from accidentally slipping out. Four transparent acrylic splash guards 6 surround the machining area and allow the operator to visually monitor the process.Beneficial technical effects: The moving motor 15 drives the moving lead screw 27 in conjunction with the limiting strip 21 to achieve precise lateral adjustment of the moving plate 22. Combined with the inclined guide on the trapezoidal block 20, the stability and straightness of the adjustment process are ensured, avoiding machining errors caused by motion deviation. The rotary motor 26 and the rotating motor drive the rotating plate 29 to flip and the clamping plate 23 to rotate, respectively. Together with the annular cylinder 8 and the annular cylinder 18, they form a stable rotary clamping structure, realizing multi-axis linkage between the C-axis and the A-axis or B-axis, and meeting the requirements of five-axis milling and turning composite machining. The machining requirements are met; the two support columns 14 in the support assembly provide high-rigidity vertical support for the mounting frame 13. The transverse motor 9 drives the transverse lead screw 10 in conjunction with the two limit bars 11 to achieve high-precision transverse movement of the moving frame 12. The self-locking property of the lead screw drive ensures that the moving frame 12 will not be displaced due to cutting force after the drive stops. The electric push rod 24, in conjunction with the two limit bars 25, enables the rapid and accurate positioning of the equipment frame 38 in the Z-axis direction. The combination of the spray head 37 and the annular air curtain box 4 achieves cooling and lubrication of the machining area and splashing of cutting fluid. Effective isolation; the tool changing assembly drives the electric push rod 2 via the switching motor 32 to move the tool changing rod 3, which works in conjunction with the side-mounted tool magazine 17 and the mounting box 2 to achieve rapid and automatic tool changing of the tool 16. The annular baffle 1 improves the safety of tool storage. The connecting frame 39 integrates all components on the side of the support column 14, shortening the tool changing stroke. In the liquid collection assembly, the pull-out box 7 is slidably set inside the support box 5. Four mesh partitions 31 divide the interior into a liquid storage chamber and two liquid collection chambers. Two discharge ports 35 correspond to the liquid collection chambers to achieve directional collection of waste liquid and filtration. The filter box 36 and the mesh partition 31 form a dual filtration mechanism. The submersible pump delivers clean cutting fluid to the spray head 37 through a hose to achieve closed-loop recycling. The pull-out design of the pull-out box 7 facilitates the cleaning and replacement of the filter box 36. The entire machining center highly integrates the adjustment components, rotating clamping mechanism, moving components, tool changing components, and fluid collection components on the support box 5. The components are arranged in separate zones without interfering with each other. Multifunctional integration of five-axis turning and milling composite machining is achieved in a limited space, improving the space utilization, processing efficiency, and service life of the equipment.
