Traditional CNC machine tools are generally only equipped with one feed assembly and can only perform a single and simple process mode, with low machining efficiency. When the workpiece needs to be processed in multiple processes, frequent manual tool changes are required to meet the processing of multiple processes. Such a structural design obviously cannot meet the diverse needs of users, so it is necessary to improve it. Utility Model Content

[0024] The following are only preferred embodiments of the present invention, and do not limit the protection scope of the present invention.

[0025] like Figures 1 to 7 As shown, the utility model provides a multi-mode multi-channel CNC machine tool, including a spindle case 1, a spindle assembly 2 mounted in the middle of the spindle case 1, and multiple groups of feed assemblies 3 arranged around the spindle assembly 2, the spindle assembly 2 is provided with a rotary chuck 20 for clamping the workpiece, and the multiple groups of feed assemblies 3 can process the workpiece in the rotary chuck 20, wherein each feed assembly 3 is provided with a slidably arranged tool holder 30, a mounting seat 31 detachably mounted on the tool holder 30, and a cutting kit mounted on the mounting seat 31, and the cutting kit is arranged as a CNC tool 301, a multi-tool kit, a nozzle guide sleeve 33, a tail butt support member 35 or a milling cutter kit 34.

[0026] The utility model realizes rapid processing of workpieces by processing the workpieces synchronously or individually through multiple groups of feed components 3, and freely selects suitable cutting kits at the driving ends of the multiple groups of feed components 3 to meet the diversified needs of multiple processes. For example, multiple CNC tools can be assembled at the same time through the multi-tool kit to meet the needs of turning, milling, drilling or tapping the workpiece, and the nozzle guide sleeve 33 can be extended to clamp the workpiece to meet the clamping of slender materials. Such structural design is very clever, and the factory can select and assemble it according to needs to form a variety of modes or combination modes, which is highly practical.

[0027] During specific use, various types of cutting kits are fixedly assembled on the mounting seat 31 , and can be disassembled by directly replacing the mounting seat 31 .

[0028] The numerical control tool 301 may be a lathe tool, a milling cutter, a drill bit, a hole drill, a flower drill and a tapping tool.

[0029] In a more specific implementation scheme, the number of the feed components 3 is preferably five groups, forming five feed channels that can move synchronously or independently. Such a structural design is ingenious. The five feed components 3 can work independently and cooperate with each other for synchronous processing. The processing speed is fast and the versatility is strong, and it can meet multiple process requirements at the same time.

[0030] In a more specific implementation scheme, the plurality of groups of feed assemblies 3 are distributed in a semi-fan shape or a semi-circle. Such a structural design facilitates the synchronous processing of various surfaces of the workpiece.

[0031] More specifically, the tool holder 30 is provided with a plurality of first limiting holes 300, and the mounting seat 31 is provided with a plurality of second limiting holes 310. The mounting seat 31 is assembled to the tool holder 30 through a locking member 32. The locking member 32 passes through the second limiting holes 310 and the first limiting holes 300 in sequence to lock the mounting seat 31 to the tool holder 30. Such a structural design is simple and can be quickly disassembled and assembled. The locking member 32 can be a bolt or a screw. In addition, in a more preferred scheme, the array of the plurality of the first limiting holes 300 is triangular. Such a structural design has higher stability and higher processing accuracy. Similarly, the array of the plurality of the second limiting holes 310 is also arranged in a triangular structure.

[0032] In a feasible implementation scheme, Figure 2-3 As shown, the cutting kit of at least one of the feed assemblies 3 is configured as a nozzle guide sleeve 33, and the central axis of the nozzle guide sleeve 33 is aligned parallel to the central axis of the rotary chuck 20. The nozzle guide sleeve 33 is used to extend the clamp to form a nozzle mode, which is suitable for the processing of slender parts.

[0033] In another possible embodiment, Figure 4 As shown, the cutting kit of at least one of the feed assemblies 3 is configured as a multi-tool kit, which includes a plurality of CNC tools 301 mounted side by side on a mounting seat 31. Such a structural design forms a multi-tool mode.

[0034] In another possible embodiment, Figure 5 As shown, at least one cutting kit of the feed assembly 3 is configured as a tail butt support member 35, and the tail butt support member 35 has a support groove 350, and the central axis of the support groove 350 is aligned parallel to the central axis of the rotary chuck 20. Such a structural design forms a tail butt support mode, which can support large workpieces through the support groove 350 and reduce the amount of tail butt residue.

[0035] In another feasible implementation, at least two of the feed assemblies 3 are horizontally arranged relative to the rotary chuck 20, and the cutting kits of the two feed assemblies 3 are configured as milling cutter kits 34 to form a double milling mode.

[0036] The milling cutter kit 34 includes a milling cutter driving component 340 fixedly mounted on the mounting seat 31 and a milling cutter 341 drivingly connected to the milling cutter driving component 340 .

[0037] More specifically, if Figure 6 As shown, when the central axes of the two milling cutters 341 are perpendicular to the central axis of the rotating chuck 20, a double-sided milling mode can be formed. Figure 7 As shown, when the central axis of one milling cutter 341 is perpendicular to the central axis of the rotating chuck 20 and the central axis of the other milling cutter 341 is parallel to the central axis of the rotating chuck 20, an end milling and side milling mode can be formed.

[0038] In this embodiment, it also includes a machine table 4 and an automatic unloading mechanism 5. The spindle box 1 is installed on the machine table 4. The automatic unloading mechanism 5 includes a material receiving channel 50, a material receiving belt 51 and a material receiving frame 52 fixed to the machine table 4. The material receiving channel 50 is tilted and extends to the position of the rotating chuck 20. Specifically, the workpiece automatically falls into the material receiving channel 50 after processing, and then the material receiving belt 51 conveys the workpiece in the material receiving channel 50 into the material receiving frame 52, thereby realizing automatic material receiving with a high degree of automation.

[0039] In a further technical solution, each feed assembly 3 is also provided with a first fixed seat 36 fixedly mounted on the spindle housing 1, a first driving member 37 mounted on the first fixed seat 36, a second fixed seat 38 drivingly connected to the first driving member 37, and a second driving member 39 mounted on the second fixed seat, and the tool seat 30 is slidably mounted on the second fixed seat 38.

[0040] Among them, the first driving member 37 is used to drive the second fixed seat 38 to slide along the first axial direction, and the second driving member 39 is used to drive the tool seat 30 to slide along the second axial direction. The first axial direction and the second axial direction are vertically crossed. Such a structural design can adjust the specific position of the cutting kit in two axes with higher precision.

[0041] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
