[0002] Milling is a machining method that uses a rotating multi-edged cutting tool (milling cutter) to cut a workpiece. It is widely used in the forming and finishing of materials such as metals and plastics. Its core feature is that the cutting tool rotates while the workpiece moves. Through the axial or radial feed of the milling cutter, complex contours such as planes, grooves, gears, and threads can be machined.

[0003] Milling is a metalworking method that uses a rotating cutting tool to cut a workpiece, and it is widely used in the machinery manufacturing industry. A milling machine mainly consists of core components such as the bed, spindle system, worktable, and feed mechanism. CNC milling machines are also equipped with a CNC control system. During machining, a high-speed rotating milling cutter removes material through climb milling or conventional milling, and can machine complex surfaces such as planes, grooves, and gears. Modern machining centers generally use automatic tool changers, enabling rapid tool changes via robotic arms or direct spindle tool changing.

A positioning component is installed on the inner wall of the housing 1. The positioning component is used to fix the workpiece and ensure machining accuracy.

[0033] refer to Figure 2 and Figure 3 The drive assembly includes a moving motor 2, which is externally fixedly connected to the inner wall of the housing 1. A lead screw 3 is fixedly connected to the drive end of the moving motor 2, which converts rotational motion into linear motion. A threaded block 4 is threadedly connected to the external of the lead screw 3, which moves along the lead screw 3 to adjust the position of the tool 16. An electric slide rail 5 is fixedly connected to the bottom of the threaded block 4, which provides movement in another direction to achieve multi-axis control. A sliding block 9 is slidably connected to the bottom of the electric slide rail 5, which moves along the electric slide rail 5 to adjust the longitudinal position. A hydraulic cylinder 10 is fixedly connected to the bottom of the sliding block 9, which controls lifting and lowering to adapt to different processing depths. The drive end of the hydraulic cylinder 10 is fixedly connected to the top of the protective housing 11.

[0034] Two limiting rods 7 are fixedly connected to the inner wall of the housing 1. The limiting rods 7 restrict the movement trajectory of the electric slide rail 5 to prevent deviation. Extension blocks 6 are fixedly connected to both sides of the top of the electric slide rail 5. The extension blocks 6 cooperate with the limiting rods 7 to ensure smooth movement. The through holes of the extension blocks 6 are slidably connected to the outside of the limiting rods 7. Two limiting plates 8 are fixedly connected to the inner wall of the housing 1. The limiting plates 8 further constrain the movement of the electric slide rail 5 and improve stability. The outside of the electric slide rail 5 is slidably connected to the inner wall of the limiting plates 8 to form a double guide and reduce vibration.

[0035] The collection assembly includes a collection box 17, which stores processing debris for easy centralized cleaning. The collection box 17 is externally fixedly connected to the inner wall of the housing 1. A suction pump 18 is installed on the top of the collection box 17. The suction pump 18 generates negative pressure to suck away the processing debris. A connecting pipe 19 is fixedly connected to the output end of the suction pump 18. The connecting pipe 19 transports the debris to the collection box 17. Multiple suction heads 20 are fixedly connected to the outside of the connecting pipe 19.

The outside of the shell 13 is slidably connected to the bottom of the protective shell 11 to ensure that the debris can be effectively collected during processing.

[0036] The positioning assembly includes a positioning motor 21, which drives the clamping mechanism to fix the workpiece. The positioning motor 21 is externally fixedly connected to the inner wall of the housing 1. A rotating plate 22 is fixedly connected to the driving end of the positioning motor 21. The rotating plate 22 converts the rotational motion of the motor into a clamping action. Connecting rods 23 are rotatably connected to both sides of the rotating plate 22. The movement of the connecting rods 23 achieves clamping or loosening. A sliding plate 24 is rotatably connected to the other end of the connecting rods 23. The sliding plate 24 can adjust the clamping range. A positioning block 25 is fixedly connected to the top of the sliding plate 24. The positioning block 25 directly contacts the workpiece to ensure stable clamping. A sliding groove is provided on the inner wall of the housing 1. The outer side of the positioning block 25 is slidably connected to the inner wall of the sliding groove. The sliding groove guides the movement of the positioning block 25 to ensure clamping accuracy.

[0037] Working principle: When the equipment is needed, the workpiece to be processed is placed on the inner wall of the housing 1. At this time, the positioning motor 21 is started, which drives the rotating plate 22 to rotate. The rotation of the rotating plate 22 drives the connecting rod 23 to rotate, and the rotation of the connecting rod 23 causes the sliding plate 24 to move. The movement of the sliding plate 24 drives the positioning block 25 to move, and finally the movement of the positioning block 25 fixes the workpiece to achieve the clamping effect.

[0038] After clamping, the moving motor 2 can be started, which will drive the lead screw 3 to rotate. The rotation of the lead screw 3 will drive the threaded block 4 to move. The movement of the threaded block 4 controls the position of the electric slide rail 5. The sliding block 9 slides on the bottom of the electric slide rail 5, which can adjust the XY axis. Finally, the hydraulic cylinder 10 can be started to drive the protective shell 11 to move for processing. Before processing, the cylinder 12 needs to be started to control the shell sleeve 13 to move. The movement of the shell sleeve 13 drives the processing motor 14 to move the drive rod 15 and the tool 16, so that the tool 16 is exposed from the bottom of the protective shell 11. The processing motor 14 is started to drive the drive rod 15 to rotate the tool 16 for processing. Different tools 16 can be installed by multiple sets of tools 16 to improve the efficiency of tool 16 replacement.

[0039] Finally, during processing, the suction pump 18 is activated to generate suction in the connecting pipe 19, which in turn generates suction in the suction head 20. This allows the debris and powder generated during processing to be collected by the connecting pipe 19, and ultimately the debris enters the collection box 17 for collection.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
