The worm gear 8 is driven to rotate through the driving assembly, thereby driving the movement of the sleeve 6, and cooperating with the foot support 7 to adjust the flatness. At the same time, cooperating with the pigment water in the water tank 9, the flatness of the base is judged. The L-shaped water tank 9 can provide at least three reference points that are not on the same straight line, so as to achieve a more accurate judgment of the flatness of the base. Compared with the existing device, it avoids the problem of complex operation that often needs to be operated with a professional level in order to achieve more precise adjustment, thereby improving processing efficiency.

[0023] Reference Figure 4-5 A sliding groove 10 is provided on the bottom surface of the box body 1, and a slider 11 is slidably provided in the sliding groove 10. A cavity 12 is provided under the plurality of sliding grooves 10, and a synchronization component for driving the plurality of sliders 11 to approach each other is provided in the cavity 12. The plurality of sliders 11 are brought close to each other by the synchronization component, thereby fixing the workpiece.

[0024] Reference Figure 1-3 The sleeve 6 is fixedly connected to the limiting blocks 13 on both sides, and the sliding hole 3 is provided with limiting grooves 14 for the limiting blocks 13 to move. The limiting blocks 13 cooperate with the limiting grooves 14 to prevent the sleeve 6 from rotating with the threaded rod 5, thereby improving the stability of the device.

[0025] The driving assembly includes a worm 15 which is laterally rotatably connected to the chamber 4, and the worm 15 is meshed with the worm wheel 8. One end of the worm 15 extends to the outside of the housing 1 and is fixedly connected to a knob 16. The worm 15 drives the worm wheel 8 through the knob 16. The knob 16 can also be replaced with a small motor. The combination of the worm wheel 8 and the worm 15 can avoid the passive rotation of the threaded rod 5 while improving the accuracy of the adjustment.

[0026] The total amount of pigment water is half of the volume of the water tank 9. A horizontal line 17 is provided on the side of the water tank 9, and the horizontal line 17 is located in the middle of the water tank 9.

[0030] Working principle:

[0031] The five-axis machining center uses an adjustable flatness base. When using the base, observe the water level line of the water tank 9 and the horizontal line 17. If they are inconsistent, rotate the knob 16 to drive the worm 15 to rotate, thereby driving the worm wheel 8 and the threaded rod 5 to rotate, thereby driving the sleeve 6 and the foot support 7 to move vertically until the water level line of the water tank 9 coincides with the horizontal line 17. At this time, place the workpiece at the center of the box body 1, and turn on the motor to drive the rotating disk 18 to rotate. The threads 19 on the rotating disk 18 drive multiple tooth plates 20 to move synchronously until the buffer pads 22 on the multiple sliders 11 are simultaneously fitted, that is, the workpiece is fixed. At this time, turn on the cutter head assembly to process the workpiece. The above is the entire use process of the five-axis machining center with adjustable flatness.
