and step 3: the worker can also control the station moving mechanism (3) to drive the station assembly (4) on the other side to move to the lower side, the electric clamping jaw (46) releases the clamping connection state with the clamping seat (35) and simultaneously controls the controller (2) to sequentially start the second motor (512) and the third motor (519) in the accurate positioning unit (5) in the station assembly (4), the second motor (512) drives the bevel gear (513) on the corresponding position to rotate by taking the output end of the second motor as the axis, so that the bevel gear (513) on the rotating seat (511) drives the rotating seat (511) to rotate, the second connecting seat (518) is driven to circumferentially move by taking the axis of the connecting pin shaft of the rotating seat (511) as the vertex, the second connecting seat (518) drives the first connecting seat (517) to move towards the outer end of the inner side or the outer side, so that the first connecting seat (517) drives the third rotating shaft (514) to drive the driving rotating rod (515) to swing in the clockwise direction or the anticlockwise direction, further changing the circumferential motion into angular motion, enabling the first connecting seat (517) to enable the sliding block (58) to drive the rack block (59) to move inwards under the limiting action of the guide rail (57) under the matching of the first connecting rod (516), enabling the gear (510) to drive the second rotating shaft (54) to drive the driving rod (55) to rotate inwards under the action of the rack block (59) due to the meshing of the rack block (59) and the gear (510), further enabling the driving rod (55) to drive the shell (56) to move outwards under the limiting action of the limiting rod (53), enabling the shell (56) to be in contact with the inner wall of the annular guide rail (31) to achieve braking, enabling the third motor (519) to drive the lead screw and screw rod (520) to rotate, enabling the lead screw and nut seat (521) to move outwards under the rotating action of the lead screw and screw rod (520) and the limiting action of the limiting slide rail (522), so that the screw nut seat (521) drives one end of the second connecting rod (524) to move outwards, the second connecting rod (524) pushes the brake rod (523) to move out of the inner cavity of the shell (56) and contact with the upper side and the lower side of the inner wall of the annular guide rail (31) to realize auxiliary fixation, and a worker can control the station moving mechanism (3) to drive the station assembly (4) provided with the corresponding workpiece to move so as to realize different milling processing.
