Please refer to Figures 1 to 4. The embodiment of the present invention provides a multi-axis linkage multi-station CNC machine tool, including a base 1, an outer cover 11, a rodless cylinder 2, a carrier 21, a lateral module 22, a vertical module 23, a slide 24 and a slide 25. The base 1 is provided with an outer cover 11 on the upper part, and the outer cover 11 surrounds the machine tool body. Two rodless cylinders 2 are symmetrically installed on the upper surface of the base 1, and the two rodless cylinders 2 are slidably provided with a carrier 21. The top of the two lateral modules 22 is installed between the two There is a transverse module 22, on which a slide 24 is slidably arranged, on which a vertical module 23 is installed, on which a slider is slidably arranged. The rodless cylinder 2 can drive the carrier 21 and the transverse module 22 to move horizontally longitudinally, while the transverse module 22 can drive the slider 24 and the vertical module 23 to move horizontally transversely, and the vertical module 23 can drive the slider 25 to move up and down in the vertical direction, so that the three-axis drive function of the machine tool can be realized.

Please refer to Figures 4, 5 and 8. In the embodiment of the present invention, a switching mechanism 3 is also included. The switching mechanism 3 is composed of a mounting platform 31, a hollow turntable 32, a drilling and tapping motor 33, a drilling and tapping piece 34, an unlocking ring 35, a driving motor 36, a full gear 37 and a gear ring 38. The front side of the slider 25 is fixed with a mounting platform 31 by bolts. The front part of the mounting platform 31 is rotatably connected with the hollow turntable 32. The front end of the mounting platform 31 is installed with a drilling and tapping motor 33. The output shaft of the drilling and tapping motor 33 is vertically downward. Six drilling and tapping pieces 34 are evenly spaced on the front side of the hollow turntable 32. The six drilling and tapping pieces 34 are arranged around the drilling and tapping motor 33. When the drilling and tapping pieces 34 rotate with the hollow turntable 32 to face vertically downward, they can be docked with the drilling and tapping motor 33 and can be used in the drilling and tapping process. The mounting platform 31 is driven by the motor 33 to operate, and an unlocking ring 35 is further provided at the front of the mounting platform 31. The unlocking ring 35 is provided with two bevel teeth. The lower bevel teeth can assist the initial drilling and tapping part 34 to disengage from the drilling and tapping motor 33, and the higher bevel teeth can ensure that the next drilling and tapping part 34 is docked with the drilling and tapping motor 33 when it is in a vertical downward state. A driving motor 36 is installed on the upper part of the mounting platform 31, and a full gear 37 is provided at the front end of the output shaft of the driving motor 36. A gear ring 38 is arranged around the outer wall of the hollow turntable 32, and the full gear 37 and the gear ring 38 are meshed with each other. The driving motor 36 drives the full gear 37 to rotate clockwise, which can drive the gear ring 38 and the hollow turntable 32 to rotate accordingly, thereby replacing the drilling and tapping part 34.

Please refer to Figures 6 to 8. The drilling and tapping member 34 is composed of a guide column 341, a mounting block 342, a milling cutter 343, a socket 344, a pinion I 345, a pinion II 346 and an elastic member 347. Six pairs of guide columns 341 are evenly spaced on the front side of the hollow turntable 32. The two pairs of guide columns 341 are slidably connected to the mounting block 342, and an elastic member 347 is arranged between the mounting block 342 and the corresponding guide column 341. The elastic member 347 adopts a spring. A milling cutter 343 is rotatably arranged in the middle of each mounting block 342, and the milling cutters 343 on different mounting blocks 342 have different specifications, and a pinion II 34 is fixedly arranged on the top of each milling cutter 343. 6. A pinion I 345 is fixedly provided at the bottom of the output shaft of the drilling and tapping motor 33. When the bottom end of the milling cutter 343 is vertically downward, the pinion I 345 and the pinion II 346 can fit together. At this time, starting the drilling and tapping motor 33 can drive the milling cutter 343 to rotate, and the drilling and tapping member 34 cooperates with the helical teeth on the unlocking ring 35 through the mounting block 342. When the hollow turntable 32 rotates clockwise, the mounting block 342 will contact the inclined part of the helical teeth on the unlocking ring 35 and slide along the inclined part. At the same time, the mounting block 342 will be squeezed by the helical teeth and slide forward along the corresponding guide column 341, so that the pinion I 345 is disengaged from the corresponding pinion II 346.

In the embodiment of the present invention, if a CNC machine tool is needed to process different parts, the worker can start the drive motor 36 to make the full gear 37 rotate counterclockwise. Under the meshing action of the full gear 37 and the gear ring 38, the gear ring 38 will drive the hollow turntable 32 to rotate clockwise. At this time, the mounting block 342 on the initial drilling and tapping part 34 will slide along the helical teeth on the unlocking ring 35 and be squeezed by the helical teeth, so that the initial mounting block 342 and the initial milling cutter 343 slide forward along the guide rod 41, and the initial milling cutter 343 is pressed. The small gear II 346 on 43 will then disengage from the small gear I 345. At the same time, the mounting block 342 and the milling cutter 343 on the next drilling and tapping part 34 will make the same movement. When the initial drilling and tapping part 34 turns away, the next drilling and tapping part 34 will just completely pass through the helical teeth. The elastic part 347 will then pull the mounting block 342 to reset. When the next drilling and tapping part 34 rotates to a vertical downward state, the small gear II 346 on the corresponding milling cutter 343 can just complete the engagement with the small gear I 345.

Please refer to Figures 6 and 9. In the embodiment of the present invention, a limit mechanism 4 is also included. The limit mechanism 4 is composed of a guide rod 41, a limit piece 42 and a latch block 43. A plug hole 344 is provided on the front side of each mounting block 342. Two guide rods 41 are symmetrically arranged on the front side of the casing of the drilling and tapping motor 33. The two guide rods 41 are slidably connected to the limit piece 42, and a return spring is arranged between the limit piece 42 and the guide rod 41. The bottom of the limit piece 42 is fixedly connected to the latch block 43, and the latch block 43 can be inserted into the plug on the mounting block 342. In the hole 344, the bottom of the latch block 43 is set to an arc surface, and the left and right sides of the latch block 43 are both cut corners. After the drilling and tapping part 34 and the drilling and tapping motor 33 are connected, the latch block 43 will be inserted into the socket 344, and the drilling and tapping part 34 will be limited and fixed in cooperation with the limiting part 42, thereby improving the axial stability of the drilling and tapping part 34 when working. Moreover, since the bottom of the latch block 43 is an arc surface and the left and right sides are both cut corners, when the hollow turntable 32 drives the drilling and tapping part 34 to rotate, the latch block 43 can slide out of the socket 34 smoothly.

Please refer to Figures 2 and 10. In the embodiment of the present invention, a material table 12 and a clamping mechanism 5 are also included. The clamping mechanism 5 is composed of an adjustment motor 51, a support seat 52 and an electric clamping member 53. The material table 12 is fixedly installed at the middle position of the upper surface of the base 1 by bolts. Two support seats 52 are fixedly connected to the material table 12 in a front-to-back symmetrical manner. Each of the two support seats 52 is rotatably connected to an electric clamping member 53. The electric clamping member 53 is divided into a main body and a clamping member. The main body is rotatably connected to the support seat 52, and the main body has a built-in power source. The power source can drive the clamping member to rotate relative to the main body. The material table 12 is symmetrically installed with an adjustment motor 51 in a front-to-back manner. The output shaft of the adjustment motor 51 is fixedly connected to the main body of the corresponding electric clamping member 53, and can drive the electric clamping member 53 to rotate as a whole.

In the embodiment of the present invention, when the surface of the workpiece is irregular, the power source inside the electric clamp 53 can be used to rotate the clamping part relative to the main body, and the adjustment motor 51 can also be used to drive the electric clamp 53 to rotate as a whole. Both methods can adjust the processing angle of the workpiece. By coordinating the two methods, the application scope of the machine tool can be expanded.
