Description

Technical Field

[0001] This invention belongs to the field of vertical lathe technology, specifically relating to a vertical lathe milling and turning composite machining function expansion device. Background Technology

[0002] Vertical lathes, also known as vertical turning lathes, are important turning and milling composite machining equipment in the field of mechanical processing. They are mainly used for precision turning and milling of large, large-diameter disc, ring, and cylindrical workpieces. Compared with horizontal lathes, they adopt a vertical spindle layout and vertically clamp the workpiece, which has the advantages of strong load-bearing capacity, good clamping stability, and suitability for machining large and heavy-duty workpieces. They are widely used in industries such as engineering machinery, aerospace, mold manufacturing, and precision parts processing, and are the core equipment for achieving precision machining of large and medium-sized metal workpieces.

[0003] Most existing vertical lathes consist of a housing base, vertical guideways, independent turning mechanisms, milling mechanisms, and a fixed chuck structure. The overall structure is relatively fixed. The machining mechanism achieves vertical feed along the vertical guideways, and the fixed chuck completes workpiece clamping and positioning. The spindle drives the workpiece to rotate, coordinating with the cutting tool to complete basic machining operations such as turning and milling. They can meet the single-sided turning and milling needs of conventional small and medium-sized regular workpieces. They have a simple structure, are easy to operate, and can achieve batch processing of standardized workpieces, such as the existing one with announcement number CN112171307. According to Chinese patent A, the worktable of this device slides freely along the X-axis on the bed guide rail, and the slide slides freely along the Y-axis on the crossbeam guide rail, realizing the relative horizontal movement of the electric spindle and the workpiece. The ram slides freely along the Z-axis on the slide, which facilitates the electric spindle to penetrate into the workpiece. The servo rotation mechanism drives the electric spindle to swing, making the drilling and milling angle of the electric spindle freely controllable. This allows the vertical lathe to be used to turn the inner and outer circles and end faces of the workpiece, as well as to process the internal holes and planes of the workpiece, avoiding secondary clamping and improving the machining accuracy of the workpiece.

[0004] Although the aforementioned existing devices can machine internal holes and planes of workpieces without requiring secondary clamping, they still have significant technical shortcomings in actual use: 1. Most existing vertical lathe chucks are fixed structures without workpiece flipping function. When machining the bottom surface of the workpiece, it is still necessary to manually disassemble the workpiece and re-clamp and align it. Multiple clamping can easily cause positioning errors, which seriously affect the machining accuracy. In addition, the process is cumbersome and the machining efficiency is low. 2. Traditional vertical lathe conductive power supply structures are mostly central slip ring power supplies, which occupy central space and have limited aperture, making them unsuitable for through-processing and bottom processing of large-diameter hollow workpieces; 3. Traditional slip rings mostly use sliding contact conductivity, which has high frictional resistance and severe wear. They cannot meet the power supply requirements of high-speed rotating machining equipment. When the equipment is running at high speed, problems such as poor contact and power failure jamming are prone to occur, which greatly limits the machining adaptability, machining accuracy and machining efficiency of vertical lathes. It is difficult to meet the current production needs of large-size, high-precision, multi-faceted integrated composite machining. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a vertical lathe milling and turning composite machining function expansion device.

[0006] The technical solution adopted to solve the above technical problems is: a vertical lathe turning and milling composite machining function expansion device, including a housing mechanism, a slewing bearing mechanism, a rotary conductive mechanism, a chuck mechanism, a turning mechanism, and a milling mechanism. A slide mechanism is fixed on the inner side of the housing mechanism, and a connecting frame is fixed on the slide mechanism. The connecting frame has a concave arc-shaped structure. A slewing bearing mechanism is fixed on the slide mechanism. The slewing bearing mechanism includes a slewing bearing body. An insulating ring is fixed at the bottom of the inner ring of the slewing bearing body. Multiple conductive rings are embedded in the insulating ring. A first upright is fixed on the inner side of the inner ring of the slewing bearing body. An electric slip ring is fixed on the first upright. A first servo motor is installed at the top of the first upright. A rotating conductive mechanism is fixed on the slewing bearing mechanism. The rotating conductive mechanism includes an insulating fixing frame, on which multiple conductive slide rods are slidably arranged. An insulating wheel frame is fixed to one end of each conductive slide rod. A conductive metal sheet is embedded and fixed on the insulating wheel frame. A conductive wheel shaft is rotatably connected to the insulating wheel frame. A voltage-conducting wheel is coaxially fixed on the conductive wheel shaft. A top-pressure spring is sleeved on the outside of each conductive slide rod. A parallel wire is connected to the end of the conductive slide rod away from the voltage-conducting wheel. The inner side of the slewing bearing mechanism is rotatably connected to a chuck mechanism, which includes a large-diameter annular disc. Multiple jaw mechanisms are slidably connected to the chuck mechanism. A clamping drive mechanism is fixed at the bottom of the chuck mechanism. The clamping drive mechanism includes a second servo motor. A commutator is fixed at the output end of the second servo motor. A turning mechanism and a milling mechanism are installed on the inner side of the housing mechanism.

[0007] Furthermore, the housing mechanism includes a base, a housing body is fixed to the top of the base, a first vertical guide rail pair and a second vertical guide rail pair are fixed to the inner side of the housing body, a control panel is embedded and fixed to the outside of the housing body, a CNC numerical control unit is installed inside the base, and the control panel is electrically connected to the CNC numerical control unit.

[0008] Through the above technical solution, the base serves as the supporting foundation of the entire device, stably supporting the upper processing and transmission mechanisms, ensuring the overall stability and structural rigidity of the equipment. The housing body is fixed to the top of the base, providing reliable installation support for the first vertical guide rail pair, the second vertical guide rail pair, and other internal processing components. Relying on the two sets of vertical guide rail pairs, precise vertical sliding guidance can be provided for the turning and milling mechanisms respectively, ensuring the feed accuracy and motion stability during the turning and milling processes. At the same time, the externally embedded control panel, together with the CNC numerical control unit inside the base, realizes intelligent control functions such as equipment parameter adjustment, processing program input, and operation status monitoring through electrical connection, achieving precise numerical control control of the entire machine's processing actions, and significantly improving the automation level and processing accuracy of the device's turning and milling composite processing.

[0009] Furthermore, the slide mechanism includes an X-axis guide rail pair, a Y-axis guide rail pair is mounted on the top of the X-axis guide rail pair, a mounting bracket is fixed on the Y-axis guide rail pair, a main spindle motor is fixed inside the mounting bracket, a connecting plate is fixed to the output end of the main spindle motor, and the connecting plate is bolted to the connecting bracket.

[0010] Through the above technical solution, the ram mechanism relies on the X-axis guide rail pair and the Y-axis guide rail pair to form a planar dual-axis feed motion structure, which can drive the upper mounting frame to achieve precise horizontal and vertical displacement adjustment, effectively expanding the processing stroke and workpiece adaptability range of the device. The mounting frame provides a stable mounting carrier for the spindle motor, ensuring the structural stability of the motor operation. The spindle motor is bolted to the connecting frame through the connecting plate at the output end, realizing stable power transmission and rigid structural connection. It can drive the lower slewing bearing mechanism and chuck mechanism to move in a coordinated manner, and cooperate with the turning mechanism and milling mechanism to complete multi-directional, high-precision turning and milling composite machining, effectively improving the processing flexibility and overall processing adaptability of the equipment. The concave connecting frame provides clearance for the chuck mechanism to flip.

[0011] Furthermore, the outer ring of the slewing bearing body is fixed to the mounting frame, the inner ring of the slewing bearing body is fixed to the connecting frame, the plurality of conductive rings are parallel to each other, the inner ring of the slewing bearing body is fixed with a second support, and a bearing is fixed on the second support.

[0012] Through the above technical solution, the slewing bearing body utilizes the installation method where the inner and outer rings are fixed to the mounting frame and connecting frame respectively to achieve the overall rotational bearing function. It can stably support the lower chuck mechanism and workpiece and complete the angle flipping action. The insulating ring plays a role in insulating and isolating multiple sets of parallel conductive rings and fixing and positioning them, avoiding the problem of cross-current and short circuit between conductive circuits, and ensuring the stability and safety of the rotational power supply. The first stand provides a stable mounting point for the electric slip ring and the first servo motor. The electric slip ring, together with the conductive ring, can realize continuous conduction and signal transmission in the rotational state, solving the problem of power supply line entanglement and breakage under rotational conditions. The second stand and its mounted bearing can provide auxiliary rotational support for the end of the chuck mechanism, effectively improving the coaxiality and running stability of the chuck rotation and flipping process, reducing rotational wear, and further ensuring the accuracy of the overall milling and turning composite machining and the reliability of equipment operation.

[0013] Furthermore, the insulating fixing frame is fixed to the outer ring of the slewing bearing body, the voltage guiding wheel is arranged in multiple rows and at least three columns, the number of rows of voltage guiding wheels is the same as the number of conductive rings, each row of voltage guiding wheels is in rolling contact with one of the conductive rings, one end of the conductive slide rod is fixed with a terminal, and the first servo motor is electrically connected to the conductive ring.

[0014] Through the above technical solution, the insulating fixing frame is fixed to the outer ring of the slewing bearing body, providing a stable installation foundation for the entire rotating conductive mechanism and achieving overall insulation protection. Multiple sets of conductive slide rods can slide on the insulating fixing frame and cooperate with the top pressure spring to form an elastic clamping structure, so that the conductive voltage wheels in each row and column can always maintain close rolling contact with the corresponding conductive ring, effectively compensating for assembly errors and rotational runout, avoiding power failure due to poor contact. The insulating wheel frame plays an insulating isolation role, and reliable conduction between the conductive slide rod and the conductive wheel shaft is achieved by relying on the built-in conductive metal sheet. The coaxially fixed conductive voltage wheels replace the traditional sliding friction with rolling friction, which greatly reduces the wear of components during the rotating conductive process and extends the service life of the equipment. The array structure of at least three rows of conductive voltage wheels corresponds one-to-one with the conductive rings. The multi-point parallel contact significantly improves the conductive area and power supply stability. At the same time, the wiring terminals and parallel wires can be connected to the power supply and signal in a unified manner, and the conductive rings provide stable power supply to the first servo motor, which is suitable for the uninterrupted conductive needs under large-diameter and large-aperture rotation conditions, and solves the defects of the traditional slip ring center power supply structure which is limited in space and cannot be adapted to the layout of large-aperture chucks.

[0015] Furthermore, the large-diameter annular disk is fixed to the output shaft of the first servo motor. The large-diameter annular disk is a hollow structure. A shaft is fixed to one end of the large-diameter annular disk. The shaft is fixed to the inner ring of the bearing. Multiple sliding grooves are provided on the top of the large-diameter annular disk. A rotating disk is rotatably connected inside the large-diameter annular disk. The top of the rotating disk is provided with a spiral pattern. An internal toothed ring is milled on the bottom of the rotating disk.

[0016] Through the above technical solution, the large-diameter annular disc is directly connected to the output shaft of the first servo motor, and can synchronously complete the overall angle rotation of the workpiece with the servo power. The hollow structure reserves a large central passage space, which is suitable for through-processing of long cylindrical workpieces. The end shaft and the bearing on the second stand cooperate to form a double-end support structure, which improves the coaxiality and structural rigidity of the disc during rotation and rotation. Multiple sliding grooves on the top of the disc provide radial limit guidance for the chuck mechanism. The built-in rotatable rotating disc relies on the top surface vortex pattern to synchronously drive multiple sets of chucks to extend and retract synchronously. The integrated milled internal toothed ring at the bottom can receive the power of the clamping drive mechanism to complete the rotation. The overall structure reduces the radial width occupied and further enlarges the size of the central through hole of the large-diameter annular disc, taking into account both the stable clamping of the workpiece and the needs of adapting to the processing of large-sized workpieces.

[0017] Furthermore, the claw mechanism includes a claw body that is slidably connected to the slide groove. The bottom of the claw body is machined with a coiled pattern, which meshes with the spiral pattern. The inner end of the claw body is machined with clamping teeth.

[0018] Through the above technical solution, the chuck body slides and engages with the groove on the large-diameter annular disk, achieving precise limiting and stable guidance of the radial displacement of the chuck. The coil pattern at the bottom of the chuck body meshes with the spiral pattern at the top of the rotating disk, which can drive multiple sets of chuck bodies to synchronously and equidistantly converge towards the center or open outward when the rotating disk rotates, ensuring the centering and consistency of workpiece clamping. The clamping teeth set on the inner end of the chuck body can effectively increase the friction between the contact surface with the workpiece, improve the clamping firmness, and prevent the workpiece from loosening or slipping during milling and turning compound machining and flipping, ensuring the stability of the machining process and the machining accuracy of the finished product. The overall structure is compact and responsive, adaptable to the rapid clamping and positioning needs of workpieces of different specifications.

[0019] Furthermore, the clamping drive mechanism includes a second servo motor fixed to the bottom of the large-diameter annular disk. The output end of the second servo motor is connected to a commutator, and the output end of the commutator is connected to an output gear. The output gear meshes with an internal gear ring. The second servo motor is electrically connected to an electric slip ring, and the electric slip ring is electrically connected to a conductive ring.

[0020] Through the above technical solution, the second servo motor is installed at the bottom of the large-diameter annular disk and can rotate synchronously with the chuck mechanism. After the commutator changes the direction of motor power transmission, it drives the output gear to rotate. The output gear meshes with the inner gear ring at the bottom of the rotary disk, thereby driving the rotary disk to rotate in both directions to achieve workpiece clamping and unloading. The second servo motor is connected to the rotating conductive mechanism through the slip ring and conductive ring in sequence, and is continuously and stably powered while the chuck is rotating. There is no need to drag external cables, avoiding the risk of wire tangling and pulling. The entire drive structure is compact and does not occupy the space of the central through hole of the disk, ensuring the large through hole processing advantage of the large-diameter annular disk.

[0021] Furthermore, the turning mechanism includes a first vertical slide block that is slidably connected to the first vertical guide rail pair, a rotary table fixed on the first vertical slide block, a turning head mounted on the rotary table, and a turning tool fixed at the bottom of the turning head.

[0022] Through the above technical solution, the first vertical slide slides vertically along the first vertical guide rail pair inside the housing body, providing a vertical feed stroke for the turning head. The rotary table can drive the turning head to rotate and adjust the tool at multiple angles, flexibly switching the turning angle. The turning tool mounted at the bottom of the turning head, together with the chuck mechanism, clamps the rotating workpiece to complete turning processes such as outer circle and end face. The high-precision guidance of the guide rail pair ensures stable vertical feed. The rotary tool adjustment structure expands the turning processing conditions and, together with the milling mechanism, realizes integrated turning and milling composite machining.

[0023] Furthermore, the milling mechanism includes a second vertical slide block that is slidably connected to the second vertical guide rail pair, a milling head is mounted on the second vertical slide block, and a milling turret is mounted on the bottom of the milling head.

[0024] Through the above technical solution, the second vertical slide can slide stably vertically along the second vertical guide rail pair inside the housing body, providing high-precision vertical feed motion for the milling head. The milling head drives the bottom milling turret to operate. The turret can carry multiple milling cutters of different specifications to realize multiple milling processes such as drilling, grooving, and planar milling. The mechanism has independently set up guide rail pairs and turns mechanism for zoned operation, without interfering with each other's movement stroke. With the help of the flip-up chuck mechanism, it can perform multi-directional milling processing of the workpiece, realize the integration of turning and milling processes, and improve the efficiency of composite processing and the versatility of the equipment.

[0025] The beneficial effects of this invention are as follows: 1. This invention, through the cooperation of a slewing bearing mechanism, a rotary conductive mechanism, and a chuck mechanism, adds a set of machining motion axes to the original milling and turning machining, enabling the workpiece to be automatically flipped and adjusted in machining posture. The workpiece can be machined on both sides and at multiple angles without removing it and re-clamping it, effectively reducing the number of clamping operations, eliminating secondary clamping and positioning errors, and significantly improving machining accuracy and efficiency, achieving a composite machining effect of multi-faceted forming of the workpiece in a single clamping operation; 2. This invention, by setting up a rotating conductive mechanism and using a rolling contact conductive roller to replace the traditional sliding conductive structure, effectively reduces friction loss and heat wear during the rotating power supply process, adapting to the continuous and stable power supply requirements of the equipment under high-speed rotation. At the same time, this external large-diameter ring conductive layout is suitable for large-diameter rotating power supply conditions, avoids the central structural space, and provides sufficient operating space for the bottom flipping processing of the workpiece, effectively solving the problem of difficult bottom surface processing of large-sized workpieces.

[0030] like Figure 1 , Figure 3 and Figure 4 As shown, a slide mechanism 2 is fixed to the inner side of the housing mechanism 1, and a connecting frame 3 is fixed to the slide mechanism 2. The connecting frame 3 has a concave arc-shaped structure.

Precise horizontal and vertical displacement adjustment effectively expands the processing stroke and workpiece adaptability range of the device. The mounting frame 203 provides a stable mounting carrier for the spindle motor 204, ensuring the structural stability of the motor operation. The spindle motor 204 is bolted to the connecting frame 3 through the connecting plate 205 at the output end, realizing stable power transmission and rigid structural connection. It can drive the lower slewing bearing mechanism 4 and chuck mechanism 6 to move together, and cooperate with the turning mechanism 9 and milling mechanism 10 to complete multi-directional, high-precision turning and milling composite machining, effectively improving the processing flexibility and overall processing adaptability of the equipment. The recessed connecting frame 3 provides clearance for the chuck mechanism 6 to flip.

[0031] like Figure 1 , Figure 5 and Figure 6 As shown, a slewing bearing mechanism 4 is fixed on the ram mechanism 2. The slewing bearing mechanism 4 includes a slewing bearing body 401 with an outer diameter of 1250 mm, an inner diameter of 800 mm, an axial rated load of 120 kg, and a radial rated load of 250 kg.

The outer ring of the slewing bearing body 401 is fixed to the mounting bracket 203, and the inner ring of the slewing bearing body 401 is fixed to the connecting bracket 3. Multiple conductive rings 403 are parallel to each other. A second support 407 is fixed to the inner ring of the slewing bearing body 401. The upper bearing 408 is fixed on the upper part. The slewing bearing body 401 is installed by fixing the inner and outer rings to the mounting frame 203 and the connecting frame 3 respectively, so as to realize the overall rotation bearing function. It can stably support the lower chuck mechanism 6 and the workpiece and complete the angle flipping action. The insulating ring 402 plays the role of insulation isolation and fixed positioning for multiple sets of parallel conductive rings 403, avoiding the problem of cross-current and short circuit between conductive circuits, and ensuring the stability and safety of rotation power supply. The first upright 404 provides a stable mounting point for the electric slip ring 405 and the first servo motor 406. The electric slip ring 405, together with the conductive ring 403, can realize continuous conduction and signal transmission in the rotation state, solving the problem of power supply line entanglement and breakage in the rotation condition.

[0032] like Figures 5-8As shown, a rotating conductive mechanism 5 is fixed on the slewing bearing mechanism 4. The rotating conductive mechanism 5 includes an insulating fixing frame 501, on which multiple conductive slide rods 502 are slidably arranged. An insulating wheel frame 503 is fixed to one end of each conductive slide rod 502. A conductive metal sheet 504 is embedded and fixed on the insulating wheel frame 503. A conductive wheel axle 505 is rotatably connected to the insulating wheel frame 503. A conductive voltage wheel 506 is coaxially fixed on the conductive wheel axle 505. The contact surface width of the conductive voltage wheel 506 is 12mm. It is made of copper-silver alloy conductive substrate, and the preload of a single wheel is 120N. It is suitable for equipment with a low-speed continuous rotation of 0~60r / min. Under electrical conditions, the maximum current carrying capacity of a single wheel is 15A. A top pressure spring 507 is sleeved on the outside of the conductive slide rod 502. A parallel wire 508 is connected to the end of the conductive slide rod 502 away from the conductive voltage wheel 506. The insulating fixing frame 501 is fixed to the outer ring of the slewing bearing body 401. The conductive voltage wheel 506 is arranged in multiple rows and at least three columns. The number of rows of the conductive voltage wheel 506 is the same as the number of conductive rings 403. Each row of conductive voltage wheels 506 is in rolling contact with one of the conductive rings 403. A terminal 509 is fixed to one end of the conductive slide rod 502. The first servo motor 406 is electrically connected to the conductive ring 403. The insulating fixing frame 501... 01 is fixed to the outer ring of the slewing bearing body 401, providing a stable installation foundation for the entire rotating conductive mechanism 5 and achieving overall insulation protection. Multiple sets of conductive slide rods 502 can slide on the insulating fixing frame 501, cooperating with the top pressure spring 507 to form an elastic clamping structure, so that the conductive voltage wheels 506 in each row and column can always maintain close rolling contact with the corresponding conductive ring 403, effectively compensating for assembly errors and rotational runout, and avoiding power failure due to poor contact. The insulating wheel frame 503 plays an insulating isolation role, and reliable conduction between the conductive slide rods 502 and the conductive wheel shafts 505 is achieved by relying on the built-in conductive metal sheet 504, in conjunction with the coaxially fixed conductive... The pressure roller 506 replaces the traditional sliding friction with rolling friction, which greatly reduces the wear of components during the rotational conduction process and extends the service life of the equipment. The array structure of the pressure rollers 506 with at least three columns in multiple rows corresponds one-to-one with the conductive ring 403. The multi-point parallel contact significantly improves the conductive area and power supply stability. At the same time, the terminal block 509 and the parallel wire 508 can be connected to the power supply and signal in a unified manner. The conductive ring 403 provides stable power to the first servo motor 406, which is suitable for the uninterrupted conduction requirements under large-diameter rotation conditions and solves the defects of the traditional slip ring center power supply structure which is limited by space and cannot be adapted to the layout of large-diameter chucks.

[0033] like Figures 9-12As shown, a chuck mechanism 6 is rotatably connected to the inner side of the slewing bearing mechanism 4. The chuck mechanism 6 includes a large-diameter annular disc 601 with a central through-hole diameter of 650mm and an overall thickness of 110mm. The large-diameter annular disc 601 is fixed to the output shaft of the first servo motor 406. The large-diameter annular disc 601 is a hollow structure. A shaft 602 is fixed to one end of the large-diameter annular disc 601, and the shaft 602 is fixed to the inner ring of the bearing 408. Multiple sliding grooves 603 are provided on the top of the large-diameter annular disc 601. A rotating disk 604 is rotatably connected inside the large-diameter annular disc 601. A spiral pattern 605 is provided on the top of the rotating disk 604, and an internal toothed ring 606 is milled on the bottom of the rotating disk 604. The large-diameter annular disc 601 is directly connected to the first servo motor 406. The servo motor 406 output shaft can synchronously rotate the entire workpiece angle with the servo power. The hollow structure reserves a large central passage space, which is suitable for through-processing of long cylindrical workpieces. The end shaft 602 cooperates with the bearing 408 on the second stand 407 to form a double-end support structure, which improves the coaxiality and structural rigidity when the disc rotates and rotates. Multiple sliding grooves 603 opened on the top of the disc provide radial limit guidance for the chuck mechanism 7. The built-in rotatable rotating disc 604 relies on the top surface vortex pattern 605 to synchronously drive multiple sets of chucks to extend and retract synchronously. The integrated milled internal toothed ring 606 at the bottom can receive the power of the clamping drive mechanism 8 to complete the rotation. The overall structure reduces the radial width occupied and further enlarges the central through hole size of the large-diameter annular disc 601, taking into account the stable clamping of the workpiece and the need for processing large-sized workpieces.

[0034] like Figure 9 , Figure 11 and Figure 13 As shown, multiple jaw mechanisms 7 are slidably connected to the chuck mechanism 6. Each jaw mechanism 7 includes a jaw body 701 slidably connected to a slide groove 603. The bottom of the jaw body 701 is machined with a spiral pattern 702, which meshes with a volute pattern 605. Clamping teeth 703 are machined on the inner end of the jaw body 701. The jaw body 701 slidably engages with the slide groove 603 on the large-diameter annular disc 601, achieving precise limiting and smooth guidance of the jaw's radial displacement. The spiral pattern 702 at the bottom of the jaw body 701 interacts with the volute pattern 605 at the top of the rotating disc 604. The meshing transmission of the 605 pattern can drive multiple sets of chuck bodies 701 to synchronously and equidistantly converge towards the center or open outward when the rotary disk 604 rotates, ensuring the centering and consistency of workpiece clamping. The clamping teeth 703 set on the inner end of the chuck body 701 can effectively increase the friction between the contact surface with the workpiece, improve the clamping firmness, and prevent the workpiece from loosening or slipping during milling and turning compound machining and flipping, ensuring the stability of the machining process and the machining accuracy of the finished product. The overall structure is compact and responsive, and adaptable to the rapid clamping and positioning needs of workpieces of different specifications.

[0035] like Figure 9 and Figure 14 As shown, a clamping drive mechanism 8 is fixed to the bottom of the chuck mechanism 6. The clamping drive mechanism 8 includes a second servo motor 801 with a rated power of 2.2kW, a rated torque of 14N·m, a maximum speed of 300r / min, and a clamping force adjustment range of 0~120kN. A commutator 802 is fixed to the output end of the second servo motor 801. The clamping drive mechanism 8 includes a second servo motor 801 fixed to the bottom of the large-diameter annular disk 601. The output end of the second servo motor 801 is connected to the commutator 802, and the output end of the commutator 802 is connected to the output gear 803. The output gear 803 meshes with the internal gear ring 606. The second servo motor 801 is electrically connected to the slip ring 405, and the slip ring 405 is connected to the conductive... The rings 403 are electrically connected. The second servo motor 801 is installed at the bottom of the large-diameter annular disk 601 and can rotate synchronously with the chuck mechanism 6. After the commutator 802 changes the direction of the motor's power transmission, it drives the output gear 803 to rotate. The output gear 803 meshes with the internal gear ring 606 at the bottom of the rotary disk 604, thereby driving the rotary disk 604 to rotate in both directions to achieve workpiece clamping and unloading. The second servo motor 801 is powered by the electric slip ring 405 and the conductive ring 403 in sequence to conduct power to the rotating conductive mechanism 5. It provides a continuous and stable power supply while the chuck is rotating. There is no need to drag external cables, avoiding the risk of wire tangling and pulling. The entire drive structure is compact and does not occupy the space of the central through hole of the disk, ensuring the large through hole processing advantage of the large-diameter annular disk 601.

[0036] like Figure 1 , Figure 15 and Figure 16As shown, a turning mechanism 9 and a milling mechanism 10 are installed on the inner side of the housing mechanism 1. The turning mechanism 9 includes a first vertical slide 901 slidably connected to a first vertical guide rail pair 103. A rotary table 902 is fixed on the first vertical slide 901, and a turning head 903 is installed on the rotary table 902. A turning tool 904 is fixed at the bottom of the turning head 903. The first vertical slide 901 slides vertically along the first vertical guide rail pair 103 on the inner side of the housing body 102, providing a vertical feed stroke for the turning head 903. The rotary table 902 can drive the turning head 903 to rotate and adjust the tool at multiple angles, flexibly switching the turning angle. The turning tool 904 mounted at the bottom of the turning head 903, together with the chuck mechanism 6, clamps the rotating workpiece to complete turning operations such as outer diameter and end face. The high-precision guidance of the guide rail pair ensures stable vertical feed. The rotary tool adjustment structure expands the turning processing conditions and can be used with milling machines. The structure 10 is designed to achieve integrated milling and turning machining. The milling mechanism 10 includes a second vertical slide 1001 that is slidably connected to a second vertical guide rail pair 104. A milling head 1002 is mounted on the second vertical slide 1001, and a milling turret 1003 is mounted at the bottom of the milling head 1002. The second vertical slide 1001 can slide stably vertically along the second vertical guide rail pair 104 inside the housing body 102, providing high-precision vertical feed motion for the milling head 1002. The milling head 1002 drives the bottom milling turret 1003 to operate. The turret can carry multiple milling cutters of different specifications to achieve multiple milling operations such as drilling, grooving, and planar milling. The mechanism has independently set up guide rail pairs and turns 9 for zoned operation, without interfering with each other's movement stroke. With the help of the flip-up chuck mechanism 6, it can perform multi-directional milling machining of the workpiece, realizing the integration of turning and milling operations, improving the efficiency of composite machining and the versatility of the equipment.

[0037] The working principle of this embodiment is as follows: A vertical lathe milling and turning composite machining function expansion device, when in use, the operator inputs the CNC program through the external control panel 105 of the housing mechanism 1, and the CNC unit inside the base 101 controls the operation of the whole machine. The slide mechanism 2 drives the mounting frame 203 to move by relying on the X-axis guide rail pair 201 and the Y-axis guide rail pair 202. The spindle motor 204 drives the overall displacement of the slewing bearing mechanism 4 through the connecting plate 205 and the connecting frame 3. The outer ring of the slewing bearing body 401 is fixed with the insulating fixing frame 501. The conductive slide rod 502 in the rotating conductive mechanism 5 is pushed by the top pressure spring 507, so that the conductive wheel 506 rolls and presses the conductive ring 403 on the insulating ring 402. The current is completed through the terminal 509, the parallel wire 508, the conductive metal sheet 504, and the conductive wheel shaft 505, and is sequentially transported to the electric slip ring 405, the first servo motor 406 and the second servo motor 801. The workpiece is placed in the large-diameter annular disk 601 of the chuck mechanism 6. Two servo motors 801 drive the bottom internal gear ring 606 of the rotary disk 604 via commutator 802 and output gear 803. The spiral pattern 605 engages with the bottom thread pattern 702 of the chuck body 701. Multiple sets of chuck mechanisms 7 synchronously tighten and clamp the workpiece along the slide groove 603. The shaft 602 cooperates with the bearing 408 on the second stand 407 to provide auxiliary support for the large-diameter annular disk 601. During processing, the first servo motor 406 can drive the chuck mechanism 6 to rotate the entire workpiece to adjust the processing angle. Inside the housing mechanism 1 The first vertical guide rail pair 103 drives the first vertical slide 901, turning head 903 and turning tool 904 to feed vertically to complete the turning operation. The second vertical guide rail pair 104 drives the second vertical slide 1001, milling head 1002 and milling turret 1003 to feed vertically to complete the milling operation. The whole device relies on the rolling conductive structure to ensure stable power supply for high-speed rotation. The large-diameter hollow disk body reserves central passage space. The workpiece can complete the front and back turning and milling composite machining in one clamping and flipping.
