[0036] Reference Figure 1 and Figure 3When cutting a workpiece, the workpiece is placed at a specific position on the lifting plate 105, and the position of the sliding door frame 103 on the supporting side plate 102 and the position of the sliding block 2 on the slide rail 104 are adjusted.

[0037] Reference Figure 2-4 , the pressure sensor 11 receives the squeeze from the limit rod 311. When the force on the cutting tool rod 309 is too large and exceeds the threshold, the clamping electromagnet 312 is powered off and loses its magnetism and separates from the connecting magnet 13 inside the clamping groove 3111.

The debris mixed with the cutting oil is discharged through the guide spiral groove 3092, which reduces the possibility of debris abrading the workpiece surface. The provision of the sealed bearing 46 reduces the possibility of the oil pipe 43 being entangled on the cutting bar 309 during its rotation.

[0039] The implementation principle of a wind turbine bearing seat milling machine and its processing technology in the embodiment of the present application is as follows: when cutting a workpiece, the workpiece is placed at a specific position on the lifting plate 105, and the position of the sliding door frame 103 on the supporting side plate 102 and the position of the sliding block 2 on the slide rail 104 are adjusted. According to the processing requirements, the angles of the connecting vertical plate 302 and the cutting tool rod 309 are adjusted by rotating the motor 5.

[0040] When the force on the cutting tool bar 309 exceeds the threshold, the limit rod 311 slides upward along the yielding arc groove 10, realizing the automatic and timely avoidance of the cutting tool bar 309. When the pressure is removed, the cutting tool bar 309 is reset under the joint action of the yielding spring 313 and the two mounting springs 306, avoiding the shaking of the cutting tool bar 309 during normal use. While cutting, the oil pump 42 injects lubricating cutting oil into the mounting ring box 45 through the oil pipe 43 to achieve lubrication and cooling of the cutting tool bar 309.
