[0026] The following is combined with Figure 1-3 This application is described in further detail.

[0027] Reference Figure 1 and Figure 3 An automatic rotary grabbing milling head comprises a housing 1 and a positioning frame 4 for fixing the milling head. A driving head 2 is arranged at the bottom of the housing 1. Both ends of the driving head 2 can rotate to increase the use effect of the milling head. A positioning seat 3 is arranged at the top of the housing 1. A positioning plate 5 is fixedly connected to the bottom of the positioning frame 4. The positioning plate 5 is fixedly connected to the machine platform by bolts. A grabbing frame 6 is fixedly connected to the top of the positioning frame 4. A clamping seat 7 is arranged inside the positioning seat 3. Four groups of positioning holes 8 are opened on the clamping seat 7. The four groups of positioning holes 8 are arranged inside A connecting column 9 is provided, and a connecting pipe 11 is provided inside the outer shell 1. The connecting pipe 11 can connect the grasping device with the milling head. A clamping plate 10 is provided inside the positioning seat 3 and on the outside of the connecting pipe 11. An arc groove 19 is opened inside the grasping frame 6. The grasping frame 6 and both sides of the arc groove 19 are fixedly connected to the limiting seat 20. Both sides of the bottom of the positioning seat 3 are fixedly connected to the limiting column 21. The limiting column 21 is clamped on the limiting seat 20, which can position the milling head during grasping, making it convenient for positioning.

[0028] Reference Figure 2A transmission gear set 12 is arranged inside the driving head 2, and a transmission shaft 13 is fixedly connected to the transmission gear set 12. A lower bearing 14, a middle bearing 15 and an upper bearing 16 are arranged on the transmission shaft 13, so that the transmission shaft 13 can stably rotate inside the housing 1 to increase the transmission effect. A transmission flange 17 is arranged on the upper bearing 16, and a positioning flange 18 is arranged on the transmission flange 17, which can rotate independently without affecting each other. An upper and lower set of internal threaded sleeves are provided inside the connecting pipe 11, and the lower threaded sleeve is threadedly connected to the axis of the transmission flange 17.
