Description

[0002] In the manufacturing of critical equipment such as aerospace, energy, and shipbuilding, it is often necessary to process large and complex components. These parts are typically characterized by their large size, heavy weight, complex shape, and high precision requirements. Traditional processing methods have the following shortcomings: 1. When using an integrated machine tool to process large parts, the machine tool itself needs a huge structure, which leads to high equipment manufacturing costs and difficulties in transportation, installation and debugging.

The workpiece spindle assembly is used to clamp the workpiece when the split six-axis five-linkage turning and milling composite machining center is running in horizontal machining mode.

[0024] Specifically, the structure corresponding to the horizontal machining mode of the split-type six-axis five-linkage turning and milling composite machining center includes a workpiece spindle assembly 205, a swivel head assembly 11, a hydraulic tailstock assembly 242, a hydraulic center frame 241, an X-axis drive assembly, a Y-axis drive assembly, and a Z-axis drive assembly. The workpiece spindle assembly 205 is used to clamp the workpiece; The oscillating head assembly 11 is used to hold the cutting tool; The hydraulic center support 241 is mounted on the hydraulic tailstock assembly 242 and is used to clamp and position the workpiece in conjunction with the workpiece spindle; specifically, the hydraulic tailstock assembly 242 and the hydraulic center support 241 are used to cooperate with the workpiece spindle to process long shaft parts. The X-axis drive assembly, Y-axis drive assembly and Z-axis drive assembly are respectively used to drive the oscillating head assembly 11 to drive the tool to move linearly along the X-axis direction, Y-axis direction and Z-axis direction; The structure corresponding to the vertical machining mode of the split-type six-axis five-linkage turning and milling composite machining center includes a rotary table 203, a tilting head assembly 11, an X-axis drive assembly, a Y-axis drive assembly, and a Z-axis drive assembly. The rotary table 203 is used to clamp the workpiece; The oscillating head assembly 11 is used to hold the cutting tool; The X-axis drive assembly, Y-axis drive assembly and Z-axis drive assembly are respectively used to drive the oscillating head assembly 11 to drive the tool to move linearly along the Z-axis direction, Y-axis direction and X-axis direction; In this embodiment, the CNC system also pre-sets an activated vertical spindle unit and an activated horizontal spindle unit according to the structure corresponding to the horizontal and vertical machining modes of the split-type six-axis five-linkage turning and milling composite machining center. The activated vertical spindle unit is used to control the split-type six-axis five-linkage turning and milling composite machining center to operate in the vertical machining mode: that is, the rotary table 203 is used to clamp the workpiece, and the rotary table 203 serves as the spindle rotation axis C-axis; the rotation axis where the swivel head assembly 11 is located serves as the B-axis rotating around the Y-axis; the X-axis drive assembly, Y-axis drive assembly, and Z-axis drive assembly are respectively used to drive the swivel head assembly 11 to enable the tool to move linearly along the Z-axis direction, Y-axis direction, and X-axis direction. The activated horizontal spindle unit is used to control the split six-axis five-linkage turning and milling composite machining center to operate in horizontal machining mode: that is, the workpiece spindle assembly 205 is used to clamp the workpiece, and the workpiece spindle of the workpiece spindle assembly 205 serves as the C-axis rotating around the Z-axis; the rotation axis of the swivel head assembly 11 serves as the B-axis rotating around the Y-axis; the X-axis drive assembly, Y-axis drive assembly, and Z-axis drive assembly are respectively used to drive the swivel head assembly 11 to enable the tool to move linearly along the X-axis, Y-axis, and Z-axis directions; The equipment switches between vertical and horizontal machining modes via a CNC system: Vertical mode (channel 1): Activates the vertical spindle unit, linking the X, Y, and Z axes with the B and C axes. In this mode, the C axis is a vertical rotary table. Based on the vertical machining process of the part (such as end milling and radial turning of disc-shaped parts), the corresponding tool and machining program are called to complete the machining of complex contours.

[0025] Horizontal mode (channel 2): ​​Switch to horizontal spindle unit, X, Y, and Z axes (axial conversion) are linked with B and C axes. At this time, the C axis is the horizontal workpiece spindle; it is suitable for processes such as internal and external turning of shaft parts and radial surface milling. The preset tool changing system and cooling chip removal system automatically adapt with the mode switch to ensure continuous and efficient machining process.

[0026] In this embodiment, activating the vertical spindle unit and activating the horizontal spindle unit are used to adjust the configuration manager in the CNC system according to the linkage of the X-axis, Y-axis, Z-axis, B-axis and C-axis, and configure the vertical and horizontal working channels according to the mechanical workpiece requirements of the machining center. The vertical and horizontal working channels are achieved by setting logical axes under different coordinate systems and encapsulating corresponding physical axes, and by changing the preset PLC logic control instructions of the CNC system to control the switching of the working channels to realize dual-channel multi-axis linkage operation. The working channels include a first working channel, namely the vertical working channel, and a second working channel, namely the horizontal working channel. The first working channel is used in a set first axis coordinate system, such as Figure 6 As shown, the rotary table 203 is controlled to clamp the workpiece, and the rotary table 203 serves as the second logical axis, namely the spindle rotation axis C-axis; the rotation axis where the swivel head assembly 11 is located is controlled to rotate around the Y-axis, and the swivel head assembly 11 serves as the third physical axis, namely the B-axis, corresponding to the second axis coordinate system; the X-axis drive assembly, Y-axis drive assembly, and Z-axis drive assembly are controlled to drive the swivel head assembly 11 to drive the tool to move linearly along the Z-axis, Y-axis, and X-axis directions, and the X-axis drive assembly, Y-axis drive assembly, and Z-axis drive assembly serve as the fourth physical axis, corresponding to the second axis coordinate system. The second working channel is used in the set second axis coordinate system, such as... Figure 7As shown, the workpiece spindle assembly 205 is controlled to clamp the workpiece, and the workpiece spindle of the control workpiece spindle assembly 205 rotates around the Z-axis, with the workpiece spindle serving as the first logical axis, i.e., the C-axis; the rotation axis of the control head assembly 11 rotates around the Y-axis, with the control head assembly 11 serving as the first physical axis, i.e., the B-axis; the control X-axis drive assembly, Y-axis drive assembly, and Z-axis drive assembly drive the control head assembly 11 to drive the tool to move linearly along the X-axis, Y-axis, and Z-axis directions, with the X-axis drive assembly, Y-axis drive assembly, and Z-axis drive assembly serving as the second physical axes. In this embodiment, the preset PLC logic control instructions of the CNC system can be changed to control the switching between the first and second working channels to achieve dual-channel multi-axis linkage operation. The methods for changing the PLC logic control instructions of the CNC system to control the working channels include manual control and code control. Using code control, specifically: S100: The working channel display interface is set through the CNC system; and the working channel display interface includes a first working channel display interface and a second working channel display interface; S101: Select two corresponding working channels according to the mechanical workpiece configuration and axis coordinate configuration. The mechanical workpiece configuration includes a workpiece spindle assembly, a rotary table, a cutting tool, an X-axis drive assembly, a Y-axis drive assembly, and a Z-axis drive assembly. The axis coordinate configuration includes coordinate axes applied to the first working channel and coordinate axes applied to the second working channel. The CNC system selects the working channel according to the workpiece processing requirements. If the first working channel is executed, the M-code of the first working channel is started, and the workpiece is machined by the CNC system. After the machining is completed, the first working channel is closed. After the first working channel is closed, if the second working channel is switched according to the workpiece processing requirements, the M-code of the first working channel is switched to the M-code of the second working channel by the CNC system, and the corresponding PLC logic control instruction is issued. S102: The second working channel receives the PLC logic control instruction, completes the channel switching, and transfers the physical axis control corresponding to the first working channel to the second working channel. The second working channel works, and the workpiece is machined by the CNC system based on the second working channel. Specifically, after the CNC system detects that the physical axis of the current working channel has no rotational speed, it issues a working channel variable. Upon receiving the working channel variable, the CNC system switches the working channel display interface, releases control of the current working channel, transfers it to the next working channel, and binds the logical axis of the next working channel to the corresponding physical axis. In actual use, the operator can select the target channel number through the channel knob or M code according to the required machine tool mechanical mode. After the PLC issues the channel switching command, it activates the preset Changel_ch channel switching algorithm module in the CNC system to control the channel control conversion. Then, the ChgPhyAxSubchan function block is used to transfer the control of the physical axis to the corresponding logical axis of the target channel, completing the complete channel switching process.

[0027] Using manual control, specifically: A rotary switch for switching working channels is set in the CNC system. The rotary switch corresponds to different working channels. After rotating the rotary switch, the rotary switch triggers a digital signal and transmits it to the CNC system of the CNC machine tool. The CNC system recognizes the digital signal and obtains PLC logic control instructions, thereby realizing the switching of axis coordinates and working channels. At the same time, if a common physical axis is involved when switching different working channels, it is judged to be a channel interlock relationship. The CNC system stops the switching of working channels and issues an alarm signal. After the control of the common physical axis is transferred, the switching of working channels resumes.

[0028] To overcome the shortcomings of existing technologies, this embodiment utilizes a split layout and dual-mode design to achieve rapid switching and coordination between vertical and horizontal processing modes. This meets the integrated processing needs of complex workpieces across multiple processes, improving processing accuracy, efficiency, and equipment flexibility. Simultaneously, it optimizes the production layout and significantly reduces overall costs. Furthermore, addressing the transportation and installation challenges of large equipment that cannot be transported as a single unit, the split design allows for separate installation and overall lifting of the individual components, enabling conventional transportation and rapid installation and commissioning.

[0031] In a specific embodiment, spiral chip conveyors 8 are symmetrically arranged on both sides of the worktable bed 201. The main function of the spiral chip conveyors 8 in this embodiment is to discharge chips from the machining area outside the CNC machine tool. The spiral chip conveyors 8 are driven by a reducer to a spiral shaft with spiral blades, pushing the chips forward to the discharge port and into a designated station. This is used to remove waste chips generated during the cutting process in workpiece machining, maintaining a clean working environment and ensuring the normal operation of the machine tool.

[0032] Furthermore, this embodiment also includes a hoisting and transfer mechanism for realizing the overall hoisting of the tool movement assembly 1 and the workpiece placement and clamping assembly 2, such as... Figures 8 to 9 As shown, it includes a hanger 31, a lifting rope 32, a shackle 33, and a lifting ring 34 to achieve overall lifting, thereby facilitating the transportation and installation of the split six-axis five-linkage dual-mode milling and turning composite machining.
