[0002] Traditional CNC machine tool positioning accuracy typically relies on the machine tool positioning system of a machining center. This system usually uses machine tool components such as the machine bed, worktable, and fixtures for positioning. However, this method has room for optimization. The positioning accuracy depends on the rigidity of these components, which usually decreases with prolonged use and environmental changes. Machining center positioning accuracy is significantly affected by environmental factors; for example, temperature and humidity affect the thermal expansion coefficient of machine tool components, thus causing changes in positioning accuracy.

Detailed Implementation
[0029] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0030] Example: Figures 1-13The illustrated dual-guide-column adjustable positioning CNC intelligent machine tool includes a part placement mechanism. The part placement mechanism includes a machine tool base plate 1, a base plate slide rail 2 fixedly mounted on the base plate 1, a placement table 3 slidably mounted on the base plate slide rail 2, a first motor 6 fixedly mounted on the placement table 3, a first guide column 7 fixedly mounted on the output shaft of the first motor 6, a second motor 8 fixedly mounted on the placement table 3, a second guide column 9 fixedly mounted on the second motor 8, and a sliding base 10 slidably mounted on the placement table 3. The sliding base 10 is simultaneously positioned on the placement table... The sliding base 10 is fixedly mounted with a movable worm gear 11, which is threadedly engaged with the first guide post 7. The second guide post 9 is also threadedly engaged with the movable worm gear 11. A placement and retraction cylinder 12 is fixedly mounted on the sliding base 10. A mechanical component 14 is placed on the telescopic end of the placement and retraction cylinder 12. A base plate motor 4 is fixedly mounted on the machine tool base plate 1. A base plate lead screw 5 is rotatably mounted on the machine tool base plate 1. The base plate lead screw 5 is fixedly connected to the output shaft of the base plate motor 4. The base plate lead screw 5 is threadedly engaged with the placement table 3. The base plate motor 4 starts, driving the base plate lead screw 5 to rotate. The base plate lead screw 5 drives the placement platform 3 to slide on the base plate slide rail 2, changing the front and rear position of the placement platform 3. The first motor 6 and the second motor 8 control the forward and reverse rotation of the first guide post 7 and the second guide post 9, respectively. When the first guide post 7 rotates forward and the second guide post 9 rotates forward, the first guide post 7 and the second guide post 9 exert a force in the same direction on the moving worm wheel 11, causing the moving worm wheel 11 to move forward and drive the sliding base 10 to slide on the placement platform 3. When the first guide post 7 rotates forward and the second guide post 9 rotates in reverse, the first guide post 7 and the second guide post 9 exert a force in the opposite direction on the moving worm wheel 11, causing the moving worm wheel 11 to drive the sliding base 10 to rotate forward in place. When the first guide post 7 rotates in reverse and the second guide post 9 rotates in the forward direction, the moving worm gear 11 drives the sliding base 10 to rotate in the opposite direction in place. When the first guide post 7 rotates in reverse and the second guide post 9 rotates in reverse, the moving worm gear 11 drives the sliding base 10 to slide in the opposite direction on the placement platform 3. In addition, the different rotation speeds of the first motor 6 and the second motor 8 can be controlled to achieve directional movement of the sliding base 10 while simultaneously achieving directional rotation, thus realizing the adjustment and positioning of the double guide posts. The movement of the sliding base 10 drives the placement shrink cylinder 12 to move. The placement shrink cylinder 12 extends to connect to the machine part 14. The placement shrink cylinder 12 retracts to retract the machine part 14. When the machine part 14 needs to be processed, the placement shrink cylinder 12 extends to place the machine part 14.
[0031] The intelligent machine tool includes a clamping mechanism, which includes a placement plate 13, which is fixedly mounted on a sliding base 10. A clamping seat 15 is fixedly mounted on the placement plate 13, and a clamping slider 16 is slidably mounted on the clamping seat 15. A clamping wheel rod 17 is rotatably mounted on the clamping slider 16, and small wheels are mounted at both ends of the clamping wheel rod 17. The machine part 14 is placed on the clamping seat 15. A connecting rod 18 is rotatably mounted on the clamping seat 15, and a slider rod 19 is fixedly mounted on the clamping slider 16. The slider rod 19 is rotatably connected to the connecting rod 18. A clamping cylinder 20 is fixedly mounted on the clamping seat 15, and the telescopic end of the clamping cylinder 20 is fixedly connected to the clamping slider 16. When the clamping cylinder 20 is activated, it drives the clamping slider 16 to slide on the clamping seat 15. The movement of the clamping slider 16 drives the clamping wheel rod 17 to move. One end of the small wheel of the clamping wheel rod 17 contacts the side of the machine part 14. The clamping wheel rod 17 moves until both ends of the small wheels of the clamping wheel rod 17 are in contact with the machine part 14, thus completing the fixation of the machine part 14. The other side of the clamping seat 15 is also provided with a clamping slider 16. The movement of the clamping slider 16 drives the slider rod 19 to move. The movement of the slider rod 19 drives the connecting rod 18 to rotate. The rotation of the connecting rod 18 drives the clamping slider 16 on the other side to move, thereby realizing the positioning and clamping of the machine part 14.
[0032] The intelligent machine tool includes an operating table mechanism, which includes an operating table frame 21. The operating table frame 21 is fixedly mounted on the machine tool base plate 1.

A lifting motor 23 is fixedly mounted on the operating table frame 21, and a lifting lead screw 24 is fixedly mounted on the output shaft of the lifting motor 23. The lifting lead screw 24 and the lifting slider 25 form a threaded engagement. When the lifting motor 23 starts, it drives the lifting lead screw 24 to rotate, which in turn drives the lifting slider 25 to move up and down, thus achieving the up and down positioning of the operating table.
[0033] A fixed plate 26 is fixedly mounted on the lifting slider 25. A positioning bracket 27 is fixedly mounted on the fixed plate 26. A positioning motor 28 is fixedly mounted on the positioning bracket 27. A positioning lead screw 29 is fixedly mounted on the output shaft of the positioning motor 28. A positioning slide plate 30 is slidably mounted on the positioning bracket 27, and the positioning slide plate 30 and the positioning lead screw 29 form a threaded engagement. When the positioning motor 28 starts, it drives the positioning lead screw 29 to rotate. The positioning lead screw 29 drives the positioning slide plate 30 to move on the positioning bracket 27. The movement of the positioning slide plate 30 realizes the left and right movement and positioning of the operating table.
[0034] A forward-moving motor 32 is fixedly mounted on the positioning slide plate 30, and a grinding screw 31 is rotatably mounted on the positioning slide plate 30. The grinding screw 31 is fixedly connected to the output shaft of the forward-moving motor 32, and a multi-directional cutting tool mechanism is slidably mounted on the positioning slide plate 30. When the forward-moving motor 32 starts, it drives the grinding screw 31 to rotate, and the grinding screw 31 drives the multi-directional cutting tool mechanism to move, thereby realizing the forward and backward movement and positioning of the operating table.
[0035] The multi-directional tooling mechanism includes a grinding slide block 33, which is slidably mounted on a positioning slide plate 30. The grinding slide block 33 and the grinding lead screw 31 form a threaded engagement. A grinding motor 37 is rotatably mounted on the grinding slide block 33. A steering main rod 38 is fixedly mounted on the output shaft of the grinding motor 37. A guide main plate 39 is fixedly mounted on the grinding motor 37. A guide motor 40 is fixedly mounted on the guide main plate 39. A guide secondary plate 41 is fixedly mounted on the output shaft of the guide motor 40. A guide secondary rod 42 is rotatably mounted on the guide secondary plate 41. A ball joint 43 is fixedly mounted on the guide secondary rod 42. The guide secondary rod 42 is rotatably connected to the steering main rod 38 through the ball joint 43. A grinding tool 44 is fixedly mounted on the guide secondary rod 42. The grinding motor 37 starts and drives the steering main rod 38 to rotate. The rotation of the steering main rod 38 drives the guide rod 42 to rotate through the ball joint 43. The guide rod 42 drives the grinding tool 44 to rotate. The grinding tool 44 rotates to grind the machine part 14. The guide motor 40 starts and drives the guide plate 41 to rotate on the guide main plate 39. The rotation of the guide plate 41 changes the direction of the guide rod 42. However, due to the action of the ball joint 43, the steering main rod 38 can still drive the guide rod 42 to rotate. The guide rod 42 drives the grinding tool 44 to rotate, changing the processing angle of the grinding tool 44.
[0036] An adjusting block 34 is slidably mounted on the grinding slider 33. A beveled rod is fixedly mounted on the fixed plate 26, forming a fit between the fixed plate 26 and the adjusting block 34. A coil spring 35 is fixedly mounted on the grinding slider 33, with one end of the coil spring 35 fixedly connected to the grinding slider 33 and the other end fixedly connected to the adjusting block 34. An adjusting rod 36 is fixedly mounted on the grinding motor 37, and the adjusting rod 36 is slidably connected to the adjusting block 34. During the sliding of the grinding slider 33 on the positioning slide plate 30, when the adjusting block 34 moves to contact the beveled rod of the fixed plate 26, the beveled rod presses the adjusting block 34 to slide upward on the grinding slider 33. The sliding of the adjusting block 34 drives the adjusting rod 36 to rotate, which in turn drives the grinding motor 37 to rotate upward, realizing the retraction of the multi-directional tool mechanism. The coil spring 35 is used to control the automatic return of the adjusting block 34.
[0037] The intelligent machine tool includes a tool switching mechanism, which comprises a clamping motor 45 fixedly mounted on a positioning bracket 27. A clamping lead screw 46 is fixedly mounted on the output shaft of the clamping motor 45. A clamping slide 47 is slidably mounted on the positioning bracket 27, forming a threaded engagement with the clamping lead screw 46. A transverse lead screw 48 is rotatably mounted on the clamping slide 47, and a clamping assembly 49 is slidably mounted on the clamping slide 47, forming a threaded engagement with the transverse lead screw 48. When the clamping motor 45 starts, it drives the clamping lead screw 46 to rotate, which in turn moves the clamping slide 47 on the positioning bracket 27, positioning the clamping assembly 49 left and right. The transverse lead screw 48 rotates on the clamping slide 47, moving the clamping assembly 49 forward and backward, positioning the clamping assembly 49 back and forth. The clamping assembly 49 temporarily clamps the grinding tool 44, facilitating the replacement of the grinding tool 44.
[0038] A tool swivel 50 is fixedly mounted on the positioning bracket 27. A tool turntable 51 is rotatably mounted on the tool swivel 50. A turntable motor 52 is fixedly mounted on the tool swivel 50. The output shaft of the turntable motor 52 is fixedly connected to the tool turntable 51. A milling cutter 53 is fixedly placed on the tool turntable 51. When the turntable motor 52 starts, it drives the tool turntable 51 to rotate. The tool turntable 51 has multiple slots. When the transverse lead screw 48 rotates, it drives the clamping assembly 49 to move back and forth. The clamping assembly 49 places the grinding tool 44 into an empty slot on the tool turntable 51. Then, the tool turntable 51 rotates, moving the milling cutter 53 to the lowest position. The clamping assembly 49 grabs the milling cutter 53 and moves it onto the guide rod 42, completing the installation of the milling cutter 53 and the guide rod 42. This completes the switching between the grinding tool 44 and the milling cutter 53, and the machine tool switches from grinding to milling.
