Description

Technical Field

[0002] CNC machine tools, short for numerical control machine tools, are automated machine tools equipped with a program control system. This control system can logically process programs with control codes or other symbolic instructions, decode them, represent them with coded numbers, and input them into the CNC device via an information carrier.

[0014] Optionally, a Y-axis motor is fixedly installed on one side of the mounting bracket, and the output end of the Y-axis motor is connected to a Y-axis lead screw installed inside the mounting bracket.

[0015] Optionally, a Z-axis motor is fixedly installed on the movable frame, and the output end of the Z-axis motor is connected to a Z-axis lead screw installed inside the movable frame.

[0016] The beneficial effects of this utility model are: This invention achieves contactless and highly stable operation of the drive shaft at ultra-high speeds by setting a unique magnetic levitation output mechanism. By utilizing the combination of a first radial magnetic levitation bearing, a second radial magnetic levitation bearing, and a thrust magnetic levitation bearing, the drive shaft is completely suspended within the inner housing. Combined with the direct drive system consisting of the built-in motor stator and motor rotor, it fundamentally eliminates the physical friction and wear of traditional mechanical bearings, enabling the spindle to easily reach and maintain extremely high speeds. At the same time, it significantly reduces the heat and vibration sources generated by friction, providing a fundamental performance guarantee and an ultra-long service life for achieving mirror surface processing. Through active control and real-time compensation, micro-vibrations during machining are greatly suppressed, ensuring the extreme stability of the tool posture. The first and second position sensors, precisely arranged in the magnetic levitation output mechanism, can monitor the minute displacement of the drive shaft under high-speed rotation and cutting load in real time with a microsecond-level response speed. Furthermore, the position of the drive shaft is adjusted through the thrust magnetic levitation bearing, allowing the drive shaft to be adjusted up and down according to the rotation speed. In addition, the first and second demagnetizing housings reduce the magnetic levitation force, effectively adjusting the position of the drive shaft according to the first and second position sensors and the rotation speed. Achieving a mirror-like surface finish directly through cutting significantly improves product quality and optimizes the production process. Because the drive shaft achieves frictionless, ultra-high speeds and micro-vibrations during machining are actively eliminated, each cutting edge of the tool can glide across the workpiece surface at high speed in a stable and uniform manner, achieving nanoscale material removal. This results in extremely low surface roughness after machining, exhibiting a high-gloss mirror finish. Not only can it manufacture precision molds or optical components with extremely high accuracy and surface finish requirements, but more importantly, it eliminates the need for subsequent polishing and grinding processes required in traditional methods, thereby significantly shortening the production cycle, reducing manufacturing costs, and making the product more competitive in the market.

[0035] In this embodiment, preferably, a Z-axis motor 208 is fixedly installed on the movable frame 207, the output end of the Z-axis motor 208 is connected to a Z-axis lead screw 211 installed inside the movable frame 207, the Z-axis lead screw 211 is threadedly connected to a positioning seat 5, a third guide rod 209 is also fixedly installed inside the movable frame 207, the two ends of the positioning seat 5 are movably connected to the third guide rod 209, and the magnetic levitation output mechanism 4 is fixedly installed inside the positioning seat 5; It should be noted that the Z-axis motor 208 is fixedly installed by the movable frame 207, and when the Z-axis motor 208 and the Z-axis lead screw 211 are running, they can drive the positioning seat 5 to adjust its height and control the magnetic levitation output mechanism 4 to adjust its height, which facilitates the fine carving of the material to be finely carved. The setting of the third guide rod 209 can maintain the stability of the positioning seat 5 for height and adjustment.

[0036] The specific operation process of this embodiment is as follows: The operator places the workpiece to be processed firmly on the worktable 3 and clamps it in place; selects a suitable milling cutter according to the processing requirements, inserts it into the milling cutter connector 403 at the bottom of the magnetic levitation output mechanism 4, and secures the milling cutter firmly by rotating the locking bolt 404. When the control system is activated, the magnetic levitation output mechanism 4 starts working, and the first position sensor 411 and the second position sensor 419 start detecting the initial position of the drive shaft 402. Based on the feedback signal, the control system precisely controls the first radial magnetic levitation bearing 412, the second radial magnetic levitation bearing 417, and the thrust magnetic levitation bearing 414 to generate electromagnetic force, so that the drive shaft 402 achieves stable non-contact levitation in the inner housing 422, and completes the initialization of the main shaft. The operator manually or semi-automatically controls the movement of the three-axis mechanism 2 through the control system to determine the machining zero point; the specific movement process is as follows: The X-axis motor 201 is controlled to rotate, and the X-axis motor 201 drives the X-axis lead screw 202 to rotate, thereby driving the moving plate 212, which is threadedly connected to it, to move smoothly along the first guide rod 213 in the X-axis direction. Control the rotation of the Y-axis motor 205, which in turn drives the Y-axis lead screw 206 to rotate, thereby driving the moving frame 207 to move along the second guide rod 210 in the Y-axis direction. Control the rotation of the Z-axis motor 208, which drives the Z-axis lead screw 211 to rotate, thereby driving the positioning seat 5, which is threaded to it, to rise and fall along the third guide rod 209, thus driving the entire magnetic levitation output mechanism 4 to move in the Z-axis direction until the tool contacts the workpiece surface or the tool setter, and the machining zero point is set. The preset machining program is initiated; the control system begins to work in coordination. When the motor stator 407 inside the magnetic levitation output mechanism 4 is energized, the motor rotor 405 drives the transmission shaft 402 to rotate at a set ultra-high speed. The X-axis motor 201, Y-axis motor 205, and Z-axis motor 208 precisely drive their respective X-axis lead screws 202, Y-axis lead screws 206, and Z-axis lead screws 211 according to program instructions, thereby driving the magnetic levitation output mechanism 4 to perform high-speed precision carving on the workpiece according to a predetermined trajectory.

[0037] Throughout the entire processing, the first position sensor 411 and the second position sensor 419 continuously feed back the dynamic position information of the drive shaft 402 to the control system. The control system adjusts the electromagnetic force of each magnetic levitation bearing in real time, actively suppresses minor vibrations caused by factors such as cutting force, and ensures the extreme stability of the processing process, thereby obtaining a mirror-level processing effect. Furthermore, the position of the drive shaft 402 is adjusted by the thrust magnetic levitation bearing 414, allowing the drive shaft 402 to be adjusted up and down according to the rotation speed. In addition, the first demagnetizing housing 413 and the second demagnetizing housing 418 reduce the magnetic levitation force, which can effectively adjust the position of the drive shaft 402 according to the first position sensor 411, the second position sensor 419 and the rotation speed. After the machining program is completed, the Z-axis motor 208 drives the magnetic levitation output mechanism 4 to lift to a safe height, and then the motor rotor 405 stops rotating. The three-axis mechanism 2 controls the tool to return to the initial position or the tool change position; the operator turns off the power of the equipment and removes the workpiece that has been mirror-finished; the entire operation process ends.
