[0019] An automatic measuring component 4 is provided on the drive processing component 3. The automatic measuring component 4 includes a connecting frame 41, which is mounted on the movable frame 36. A third guide rail 42 is mounted on the connecting frame 41, and a second slider 43 is slidably connected to the third guide rail 42. The second slider 43 is fixed to the third guide rail 42 by bolts. Loosening the bolts adjusts the position of the second slider 43 on the third guide rail 42, and tightening them fixes the position. An adjusting frame 44 is mounted on the front of the second slider 43, and a fourth guide rail 45 is provided on the front of the adjusting frame 44. A third slider 46 is slidably connected to the fourth guide rail 45 on the front of the adjusting frame 44. The fourth guide rail 45 is equipped with a grating ruler 47 and a roller 48 at its bottom. The grating ruler 47 is a high-precision LS-50 model with a measurement accuracy of ±0.001mm and an effective measurement stroke of 50mm. The roller 48 is made of 40Cr alloy steel with a diameter of 80mm and a width of 5mm. The outer surface is hardened and precision polished, with a surface roughness Ra≤0.8μm. The roller 48 is connected to the axle through a bearing to ensure that the roller 48 can rotate flexibly and reduce rolling resistance. The roller 48 is used to fit closely with the surface being processed and pushes the grating ruler 47 to make linear displacement when rolling on the surface being processed.

[0020] The drive processing component 3 is equipped with a material unloading clamping component 5. The material unloading clamping component 5 includes a first cylinder 51, which is mounted on a mounting frame 31 via a stabilizing bracket. A movable frame 52 is mounted on the output end of the first cylinder 51, and a fourth slider 53 is mounted on the movable frame 52. A fifth guide rail 54, which is slidably connected to the fourth slider 53, is mounted on the mounting frame 31. By setting the fifth guide rail 54, the stability of the fourth slider 53's forward and backward movement is improved, thus achieving a guiding effect. A second cylinder 55 is mounted on the movable frame 52, and a fifth slider 56 is mounted on the output end of the second cylinder 55. An electric chuck 57 is mounted on the fifth slider 56. A sixth guide rail 58, which is slidably connected to the fifth slider 56, is mounted on the movable frame 52 at the position of the fifth slider 56. By setting the sixth guide rail 58, the stability of the fifth slider 56's up and down movement is improved, thus achieving a guiding effect.

[0021] When in use, first start the PLC controller 100 on the main body 1 of the fully automatic curved surface milling machine, select the curved surface processing mode through the controller touch screen, and the system automatically completes the initialization self-test of the grating ruler 47, servo motor 32 and drive motor 21. Then place the curved surface workpiece of bamboo and wood products to be processed, such as wooden spoons and bamboo curved surface decorative parts, on the moving table 23, start the two automatic clamping heads on the moving table 23, and clamp the two sides of the workpiece by air pressure drive to ensure that the workpiece does not deviate during the movement. The PLC controller 100 sends a measurement preparation command to start the servo motor 32 in the processing component 3, which drives the thread rod 33 to rotate. The thread block 34 moves downward along the thread rod 33, and simultaneously drives the moving plate 35, the moving frame 36 and the automatic measurement component 4 to move downward. At the same time, the second slider 43 of the automatic measurement component 4 is manually adjusted to slide up and down along the third guide rail 42, and the third slider 46 slides up and down along the fourth guide rail 45 until the roller 48 is in close contact with the curved surface of the workpiece. The contact pressure is monitored in real time by the PLC to ensure that the pressure is 5-8N to avoid damaging the workpiece or not being in close contact. After the adjustment is completed, the positions of the second slider 43 and the third slider 46 are locked. When the start button of the PLC controller 100 is pressed, the drive motor 21 of the moving connection component 2 starts, driving the adjusting rod 22 to rotate. The moving table 23 moves at a constant speed along the first guide rail 25. The workpiece moves to the left synchronously with the moving table 23. At this time, the roller 48 rolls on the curved surface of the workpiece, driving the grating ruler 47 to perform linear displacement through the wheel axle. The grating ruler 47 collects displacement data in real time and transmits it to the PLC controller 100 through the data line. The PLC controller 100 processes the data using a preset PID algorithm, calculates the real-time curvature of the workpiece surface, generates a control signal for the servo motor 32, and controls the servo motor 32 to adjust the height of the moving frame 36 in real time, so that the milling cutter 38 driven by the rotary motor 37 always maintains a preset processing depth with the curved surface of the workpiece, realizing synchronous linkage of measurement, adjustment and processing. When the PLC controller 100 detects that the moving stage 23 has moved to the preset endpoint, the rotary motor 37 stops running and the milling cutter 38 stops rotating. Then, the first cylinder 51 of the unloading clamping assembly 5 starts, pushing the movable frame 52 forward along the fifth guide rail 54. When the electric chuck 57 moves above the workpiece, the second cylinder 55 starts, driving the fifth slider 56 to move downward along the sixth guide rail 58. The electric chuck 57 clamps the workpiece, the first cylinder 51 drives the movable frame 52 to reset, and then after the workpiece is transferred to the appropriate position, the electric chuck 57 releases, completing a single processing cycle.
