Description

Technical Field

[0001] This invention relates to the field of machining equipment technology, and in particular to a multi-functional turning and milling integrated machining center. Background Technology

[0002] In machining, lathes and milling machines are the two most commonly used processing equipment. A lathe is a machine tool that uses a cutting tool to turn a rotating workpiece, mainly used for machining shafts, discs, sleeves, and other workpieces with rotating surfaces. A milling machine uses a rotary milling cutter to machine planes, grooves, gear-split parts, and various curved surfaces. In addition, it can be used for machining the surfaces and internal holes of rotating bodies, as well as for cutting off parts. In workpiece machining, traditional machine tools have limited functions and cannot perform complex machining operations. For example, a lathe can only turn workpieces. When multiple machine tools are needed, the workpiece must be moved between them, which is not only time-consuming and labor-intensive, but also requires a significant amount of space.

[0003] As a result, milling-turning composite machine tools have emerged in the industry, integrating the functions of lathes and milling machines. This reduces the number of machines and the floor space required, saving space and enabling the completion of multiple machining processes on a single composite machine tool. It also reduces the number of setups and machining time, thereby improving production efficiency.

[0004] However, currently common milling-turning machine tools have complex structures and lack internal workpiece transport devices with movable control. During operation, they cannot automatically move and transport workpieces or adjust their orientation between different processing stages or changes in processing methods. For example, between turning and milling, milling and turning, or turning different shaft diameters, workers need to manually lift and move the workpiece between different stages, affecting the rapid and efficient connection between processing stages and increasing the labor intensity of processing workers, thus impacting the efficiency of composite processing production. To address this, some machining manufacturers equip CNC composite machine tools with articulated robotic arms. These robotic arms move and adjust the orientation of workpieces at different processing stages, replacing manual lifting and movement. However, this method increases equipment costs, and the coordination between the articulated robotic arm's movements and the milling-turning machine tool is poor, making it difficult to adjust movements to changes in processing steps. Furthermore, most current milling-turning machine tools use a single motor to drive the spindle, making it difficult to simultaneously meet the requirements of both speed and rotational angle accuracy, necessitating technological improvements. Summary of the Invention

[0005] Based on this, the present invention provides a multi-functional milling and turning machining center that can automatically move and transport the workpiece and adjust its direction between different stages of workpiece processing and changes in different processing methods, so as to achieve rapid and efficient connection between each stage and processing method, reduce the labor intensity in the processing process, and improve the efficiency of composite processing.

[0006] To achieve the above objectives, the present invention provides a multifunctional milling and turning machining center, comprising: a base; a frame mounted on the base; a rotary drive unit including a first support, a first spindle, a first chuck, and a high-speed drive motor, wherein the first support is fixedly mounted on the longitudinal front end of the frame, the first spindle is rotatably mounted on the first support around the longitudinal central axis and connected to the high-speed drive motor, and the first chuck is mounted on the front end of the first spindle; a composite machining unit including a composite tool holder, a turning tool, and a milling cutter, wherein the composite tool holder is located in the middle of the frame, and the turning tool and the milling cutter are mounted on the composite tool holder; a transport support platform mounted on the frame, configured to transport workpieces between different machining stages and to support workpieces during machining; and a controller electrically connected to the rotary drive unit, the transport support platform, and the composite machining unit.

The upper body and the lower body are arranged vertically opposite each other. The lifting and rotating drive mechanism is connected between the upper body and the lower body. The upper body is provided with a bearing part for bearing the workpiece.

[0011] Furthermore, the lifting and rotating drive mechanism includes a turntable and a linear cylinder disposed between the upper and lower seats. The turntable is disposed at the center of the lower seat and the rotating shaft is arranged vertically. The rotating drive mechanism is driven and connected to the turntable and is configured to control the turntable to rotate around the rotating shaft. The linear cylinder is provided with a movable rod that extends freely and is circumferentially fixed. The linear cylinder is disposed at the center of the turntable and the movable rod extends upward. The upper seat is connected to the movable rod.

[0012] Furthermore, the controller is equipped with a workpiece tracking unit, which is configured to monitor the dimensional information of the workpiece during the processing. The controller moves and lifts the conveying support table longitudinally according to the dimensional information of the workpiece during the processing, so that after the workpiece is processed to the set size, it is conveyed longitudinally and accurately docked with the first chuck / second chuck in the height direction. Alternatively, the controller reverses the angle of the conveying support table according to the dimensional information of the workpiece during the processing, so that after the workpiece is processed to the set size, it is conveyed longitudinally and reversed, so that the original clamping end docks with the first chuck / second chuck.

[0013] Furthermore, a second longitudinal guide rail is provided on the transverse front side of the platform, the second support is slidably mounted on the second longitudinal guide rail and connected to the second longitudinal drive mechanism, and the controller is provided with a chuck tracking unit for tracking the longitudinal position of the second chuck. The controller controls the movement of the conveying support platform according to the received longitudinal position information of the second chuck, so that the workpiece is conveyed into the second chuck after the position is adjusted.

[0014] Furthermore, the composite machining unit is also provided with a third support and a fourth support for supporting the composite tool holder.

The third support slides on the longitudinal guide rail and is connected to the third longitudinal drive mechanism. The third support is provided with a vertical guide rail. The fourth support slides on the conveying vertical guide rail and is connected to the vertical drive mechanism. The composite tool holder is connected to the fourth support.

[0015] Furthermore, the turning tool and the milling cutter are disposed on different sides of the composite tool holder, the fourth support is connected to a turntable with a rotating shaft extending laterally, the composite tool holder is disposed on the turntable and is configured to drive the composite turntable to rotate so as to adjust the turning tool / milling cutter toward the machining direction.

[0016] Furthermore, the composite tool holder is also equipped with a drill bit, and a dual-output shaft motor is arranged perpendicular to the rotation axis of the turntable on the composite tool holder. The milling cutter is connected to one end of the motor shaft, and the drill bit is connected to the other end of the motor shaft. The composite tool holder is provided with a tool wall extending outward perpendicular to the motor axis on the outside of the dual-output shaft motor, and the turning tool is connected to the outer end of the tool arm.

[0017] The technical advantages of the multi-functional milling and turning machining center provided are mainly reflected in the following aspects:

[0018] 1. By setting a rotary drive unit on the frame and a composite tool holder with a turning tool and a milling cutter in the middle of the frame, the workpiece can be driven to rotate at high speed around the central axis by the first chuck driven by the high-speed drive motor of the rotary drive unit, and the turning tool of the composite tool holder can be used to perform turning of the workpiece; alternatively, the workpiece can be milled in the presence of a stationary workpiece, in conjunction with the milling cutter of the composite tool holder. This integrated machining center has a simple structure and completes turning and milling operations with a single integrated machining center. It does not require moving the workpiece to other lathes and milling machines, nor does it require multiple clamping operations, which effectively improves production efficiency and reduces the labor intensity of the machining process.

[0019] 2. By setting up a conveyor support platform on the frame, the workpiece can be automatically moved, conveyed, and its direction adjusted between different stages of workpiece processing and changes in different processing methods. This enables rapid and efficient connection between each stage and processing method, reduces labor intensity during processing, and improves the efficiency of composite processing. There is no need to configure an external articulated robotic arm for workpiece handling. The conveying process can be adjusted according to changes in processing procedures. The operation is simple and easy to implement.

[0020] 3. During milling, the workpiece is supported at the bottom to avoid the instability problem caused by a cantilever beam structure formed by clamping the workpiece at one end, thus ensuring the stability of the workpiece during milling. During turning, the workpiece is freed from the space, creating sufficient space for high-speed rotation of the workpiece and removal of turning chips, so as to achieve smooth milling and turning.

[0038] Through extensive production practice, the inventors discovered that current milling-turning machine tools cannot automatically move and transport workpieces or adjust their orientation between different processing stages or changes in processing methods. This affects the rapid and efficient connection between processing stages, increases the labor intensity of processing workers, and impacts the efficiency of composite processing production. While configuring an articulated robotic arm increases equipment costs, its movements have poor compatibility with the milling-turning machine tool, and adjusting its movements to adapt to changes in processing steps is difficult.

[0039] To address this, the inventors developed a multi-functional turning and milling integrated machining center. A frame is mounted on a base. The first support of the rotary drive unit is fixedly mounted at the longitudinal front end of the frame. The first spindle, rotating around its longitudinal central axis, is mounted on the first support and connected to a high-speed drive motor. A first chuck is located at the front end of the first spindle. The composite tool holder of the composite machining unit is located in the middle of the frame, with the turning tool and milling cutter mounted on the composite tool holder. A conveyor support table transports the workpiece between different machining stages and supports the workpiece during machining. The provided multi-functional turning and milling integrated machining center, through controller control of the rotary drive unit, conveyor support table, and composite machining unit, can automatically move and transport the workpiece and adjust its direction between different stages of workpiece machining and changes in components and machining methods. This achieves rapid and efficient connection, reduces labor intensity during machining, and improves composite machining efficiency.

[0040] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. The descriptions of the exemplary embodiments are merely illustrative and are in no way intended to limit the invention or its application or use. The invention can be implemented in many different forms and is not limited to the embodiments described herein. In the present invention, when a particular device is described as being located between a first device and a second device, an intermediary device may or may not be present between the particular device and the first or second device.

[0041] Example 1:

[0042] like Figures 1 to 7 As shown, a multi-functional milling and turning machining center includes a base 1, a frame 2, a rotary drive unit 3, a composite machining unit 5, a conveyor support table 6, and a controller. The frame 2 is mounted on the base 1. The rotary drive unit 3 includes a first support 31, a first spindle 32, a first chuck 33, and a high-speed drive motor 34. The first support 31 is fixedly mounted on the longitudinal front end of the frame 2. The first spindle 32 is rotatably mounted on the first support 31 around its longitudinal central axis and connected to the high-speed drive motor 34. The first chuck 33 is located at the front end of the first spindle 32. As a transmission method, a pulley 35 is provided at the rear end of the first spindle 32 away from the first chuck 33. The high-speed drive motor 34 is connected to the pulley 35 via a belt, which can reduce the vibration impact during the turning process and improve the smoothness of the turning process.

[0043] The composite machining unit 5 includes a composite tool holder 54, a turning tool 56, and a milling cutter 57. The composite tool holder 54 is located in the middle of the frame 2, and the turning tool 56 and the milling cutter 57 are mounted on the composite tool holder 54. The turning tool 56 and the milling cutter 57 are oriented by the composite tool holder: when turning is required, the turning tool 56 is adjusted to face the workpiece; when milling is required, the milling cutter 57 is adjusted to face the workpiece.

[0044] The platform 2 is also equipped with a conveying support platform 6, which is configured to convey workpieces between different processing stages and support workpieces during processing. Therefore, the conveying support platform 6 can be moved and raised during implementation.

[0045] The controller 7 is electrically connected to the rotary drive unit 3, the conveying support platform 6, and the composite processing unit 5. During implementation, the controller 7 can be an industrial computer, an intelligent control device for machining, or an existing control device such as a PLC programmable controller. It can also be connected to distance sensors, speed sensors, etc., as needed to monitor the processing conditions.

[0046] The working method of the provided multi-functional turning and milling integrated machining center:

[0047] Turning: The high-speed drive motor 34 of the rotary drive unit 3 drives the workpiece to rotate at high speed around the central axis through the first chuck, and the turning tool of the compound tool post performs turning of the workpiece. During the turning process, the conveyor support table leaves the space to create enough space for the high-speed rotation of the workpiece and the discharge of turning chips.

[0048] Milling: The high-speed drive motor 34 of the rotary drive unit 3 stops rotating, the workpiece remains stationary, and the milling cutter of the composite tool table 54 moves to the position where the workpiece needs to be processed to perform milling. During this process, the first chuck supports one end of the workpiece, and the conveying support table 6 supports the bottom of the workpiece at the processing position to avoid the problem of poor stability caused by the cantilever beam structure formed by clamping the workpiece at one end, thus ensuring the stability of the workpiece milling process.

[0049] Workpiece conveying: The first chuck 33 releases the workpiece, and the conveying support table 6 receives the released workpiece, moving the position of the workpiece that needs to be milled to the milling cutter of the compound tool table 54 for milling. During the milling process, the bottom of the workpiece is supported to realize the milling process.

[0050] In a preferred embodiment, the base 1 is provided with a transverse guide rail 11, the platform 2 is slidably mounted on the transverse guide rail 11 and connected to a transverse drive mechanism, and the controller 7 is electrically connected to the transverse drive mechanism and is configured to control the transverse movement of the platform 2 and the workpiece on it, so as to facilitate the adjustment of the transverse position of the workpiece and the alignment with the milling cutter, etc.

[0051] Based on this embodiment, the provided multi-functional turning and milling integrated machining center completes turning and milling operations through a single integrated machining center. It does not require moving the workpiece to other lathes and milling machines, nor does it require multiple clamping operations. Furthermore, by setting a conveyor support table on the frame for automatic workpiece movement and orientation adjustment, it achieves rapid and efficient connection between various stages and processing methods, effectively improving production efficiency. The device has a simple structure, low operation difficulty, and is easy to implement.

[0052] Example 2:

[0053] like Figure 1 and Figure 3 As shown, based on Embodiment 1, structural optimization is carried out: the frame 2 is also provided with a conveying support platform 6, which is longitudinally reciprocating between the first support 31 and the second support 41, and is configured to transfer and convey the workpiece between the first chuck 33 and the second chuck 43, and to support the bottom of the workpiece during the workpiece milling process.

[0054] Specifically, the conveying support platform 6 includes an upper body 61, a lower body 62, and a lifting and rotating drive mechanism. The upper surface of the platform 2 is provided with a first longitudinal guide rail 21. The lower body 62 is slidably mounted on the first longitudinal guide rail 21 and connected to the first longitudinal drive mechanism. The upper body 61 and the lower body 62 are arranged vertically opposite each other. The lifting and rotating drive mechanism is connected between the upper body 61 and the lower body 62. The upper body 61 is provided with a bearing part for bearing the workpiece.

[0055] The lifting and rotating drive mechanism includes a turntable 63 and a linear cylinder 64 disposed between the upper seat 61 and the lower seat 62. The turntable 63 is located at the center of the lower seat 62 and the rotating shaft is arranged vertically. The rotating drive mechanism is driven by the turntable 63 and is configured to control the turntable 63 to rotate 180° around the rotating shaft. The linear cylinder 64 is provided with a movable rod that extends freely and is circumferentially fixed. The linear cylinder 64 is located at the center of the turntable 63 and the movable rod extends upward. The upper seat 61 is connected to the movable rod.

[0056] In this embodiment, the conveying support table can reciprocate on the entire frame to convey the workpiece between the first chuck 33 and the second chuck 43. The upper body can be raised and lowered relative to the lower body to adjust its height and achieve 180° circumferential rotation. This allows for adjustment of the front and rear end orientation of the workpiece during the conveying process, thereby changing the clamping end of the workpiece to facilitate milling and turning at both ends of the workpiece.

[0057] Preferably, the controller 7 is provided with a workpiece tracking unit, which is configured to monitor the dimensional information of the workpiece during the processing. Specifically, the workpiece tracker includes a video camera, a distance sensor, a position sensor, etc., to track the position of the workpiece; the workpiece tracker may also include a shaft diameter measuring device to measure the shaft diameter during the processing.

[0058] The controller 7 moves and raises the conveyor support 6 longitudinally based on the workpiece's dimensional information during processing, so that after the workpiece is processed to the set size, it is longitudinally conveyed and accurately docked with the first chuck 33 / second chuck 43 in the height direction. Alternatively, the controller 7 reverses the angle of the conveyor support 6 based on the workpiece's dimensional information during processing, so that after the workpiece is processed to the set size, it is longitudinally conveyed and reversed, allowing the original clamping end to dock with the first chuck 33 / second chuck 43. This design is suitable for changes in the outer diameter of the workpiece during processing. It can be flexibly adjusted according to the workpiece's processing dimensions, making it suitable for the workpiece processing process.

[0059] Example 3:

[0060] like Figure 4 As shown, the inventors further discovered that current milling and turning composite machine tools mostly use a single motor to drive the spindle, which makes it difficult to simultaneously meet the requirements of both speed and rotation angle accuracy, necessitating technological improvements. Based on Embodiment 1 and Embodiment 2, structural optimizations were made:

[0061] The multi-functional milling and turning machining center is also equipped with an angle adjustment unit 4, including a second support 41, a second spindle 42, a second chuck 43 and a servo drive motor 44. The second support 41 is located at the longitudinal rear end of the frame 2. The second spindle 42 is rotatably mounted on the second support 41 around the longitudinal central axis and connected to the servo drive motor 44. The second chuck 43 is located at the front end of the second spindle 42 and is arranged opposite to the first chuck 33.

[0062] Based on this embodiment, the milling and turning process for the workpiece is as follows:

[0063] Turning: The high-speed drive motor 34 of the rotary drive unit 3 drives the workpiece to rotate at high speed around the central axis through the first chuck, and the turning tool of the compound tool 54 is used to perform turning of the workpiece.

[0064] Workpiece conveying: The first chuck 33 releases the workpiece, the conveying support table 6 receives the released workpiece, and the workpiece is moved to the second chuck 43 for clamping.

[0065] Milling: The second chuck 43 is controlled by the servo drive motor 44 to precisely adjust the circumferential angle of the workpiece, and the milling cutter 57 of the composite tool holder 54 is used to achieve milling of the workpiece surface with different circumferential angles.

[0066] Through this optimized embodiment, the high-speed rotation of the workpiece is achieved by the high-speed drive motor 34, which meets the needs of workpiece turning; the precise angle control of the servo drive motor 44 achieves the accurate adjustment of the workpiece angle required for milling, taking into account both the requirements of speed and rotation angle accuracy.

[0067] In another preferred embodiment, a second longitudinal guide rail 22 is further provided on the transverse front side of the frame 2. The second support 41 is slidably mounted on the second longitudinal guide rail 22 and connected to the second longitudinal drive mechanism. The controller 7 is provided with a chuck tracking unit that tracks the longitudinal position of the second chuck 43. The controller 7 controls the movement of the conveying support table 6 according to the received longitudinal position information of the second chuck 43, so that the workpiece is conveyed into the second chuck 43 after the position is adjusted. The longitudinal movement adjustment setting of the second support 41 can cooperate with the conveying support table 6 to move and clamp the workpiece, and can also adjust the longitudinal position of the workpiece to meet the needs of longitudinal movement of the workpiece during milling.

[0068] Example 4:

[0069] like Figure 5 and Figure 6 As shown, the composite processing unit 5 is also provided with a third support 51 and a fourth support 52 to support the composite tool holder 54. A longitudinal guide rail 13 is provided on the back plate 12 on the lateral rear side of the base. The third support 51 is slidably mounted on the longitudinal guide rail and connected to the third longitudinal drive mechanism. The third support 51 is provided with a vertical guide rail. The fourth support 52 is slidably mounted on the conveying vertical guide rail and connected to the vertical drive mechanism. The composite tool holder 54 is connected to the fourth support 52.

[0070] During the milling and turning process of the workpiece, the longitudinal position of the composite tool holder is adjusted by the second support, and the height of the composite tool holder is adjusted by the third support, which drives the turning tool and the milling cutter to the machining position to perform milling and turning within the workpiece.

[0071] The turning tool 56 and the milling cutter 57 are disposed on different sides of the composite tool holder 54. The fourth support 52 is connected to a turntable 53 with a rotating shaft extending laterally. The composite tool holder 54 is disposed on the turntable 53 and is configured to drive the composite turntable to rotate via the turntable 53 to adjust the orientation of the turning tool 56 and the milling cutter 57 toward the machining direction. During the composite turning and milling process, the orientation of the turning tool 56 and the milling cutter 57 is adjusted by rotating the turntable to meet the machining requirements.

[0072] The composite tool holder 54 is also equipped with a drill bit 58. A dual-output shaft motor 55, arranged perpendicular to the rotation axis of the turntable 53, is mounted on the composite tool holder 54. The milling cutter 57 is connected to one end of the motor shaft, and the drill bit 58 is connected to the other end of the motor shaft. A tool wall extending outward perpendicular to the motor axis is located outside the dual-output shaft motor 55 on the composite tool holder 54. The turning tool 56 is connected to the outer end of the tool arm. The drill bit 58 and the milling cutter 57 are driven separately by the dual-output shaft motor to perform drilling and milling operations respectively. The layout is simple and meets the needs of various machining methods.
