The intelligent high-precision positioning control device for numerical control machines according to any one of claims 1-9, characterized in that: The method of the device is as follows: S1: after the inner gear one (12) rotates, the inner gear two (13) and the inner gear three (14) are sequentially driven to rotate through gear meshing, three-stage inner gear transmission realizes speed reduction and torque increase, and the transmission stability is ensured; the inner gear three (14) drives the mounting shaft (15) of the shaft center to rotate, and then drives the rear wheel (16) at the end of the mounting shaft (15) to rotate, the rear wheel (16) synchronously drives the shaft disc (41) of the shaft center to rotate, the connecting rod one (28) and the butt joint strip (39) eccentrically installed on the shaft disc (41) start linkage action under the action of rotating force, when the connecting rod one (28) rotates with the shaft disc (41), the connecting rod two (30) is pushed to swing around the hinge point, the rod sleeve (29) in the middle of the connecting rod two (30) slides up and down along the guide rod (32), realizing the conversion from swinging to linear motion, and at the same time, the connecting rod two (30) drives the push rod (31) to do vertical reciprocating motion in the inner cavity of the vertical cylinder (17), and the rod block (33) on the push rod (31) rises and falls synchronously with the push rod; S2: when the shaft disc (41) rotates, the butt joint strip (39) connected eccentrically drives the connecting piece (38) to swing left and right with the center fixed point as the shaft, the hinge rod one (35) and the hinge rod two (37) on the upper and lower parts of the connecting piece (38) do left and right reciprocating motion, the hinge plug (36) in the cylinder seat (40) is displaced along the axis, and then drives the push block (34) at the front end to do horizontal reciprocating motion; S3: since the connecting rod one (28) and the butt joint strip (39) are both eccentrically driven by the shaft disc (41), there is a fixed phase difference between the movements of the two, when the push rod (31) drives the rod block (33) to rise to the highest position, the push block (34) is just displaced to below the rod block (33) and contacts with it, realizing accurate clamping of the rod block (33), so that the opening block (23) remains in the waiting machining station, and the positioning action is completed; S4: The to-be-operated part (26) is inserted into the inner cavity of the through cylinder (24) from the opening block (23) and moves synchronously with the opening block (23); the circular wheel (27) at the bottom of the opening block (23) slides in the arc-shaped slot (25) of the slotted cylinder (10), so that the opening block (23) moves along an arc-shaped trajectory; when the opening block (23) is located at the upper and lower parts of the slotted cylinder (10), the to-be-operated part (26) is in the longest extension state; when the opening block (23) is located at the left and right parts of the slotted cylinder (10), the to-be-operated part (26) is in the shortest contraction state, realizing the trajectory conveying and station switching of the workpiece; S5: When the opening block (23) drives the to-be-operated part (26) to move to the machining station (the longest state), the push rod (31) is kept at the highest position under the locking of the clamping mechanism, and the to-be-operated part (26) is pressed and fixed in the inner cavity of the opening block (23), realizing the positioning and clamping of the workpiece; at the same time, the gear two (8) driven by the shaft rod (11) drives the meshing gear one (7) to rotate, the gear one (7) synchronously drives the compression wheel (9) to rotate, the knife wheel convex strip (20) on the outer wall of the compression wheel (9) performs compression and shaping on the to-be-operated part (26), and then the knife wheel (19) at the end of the compression wheel (9) performs precise cutting on the to-be-operated part (26), completing the machining process; S6: After cutting, the shaft disc (41) continues to rotate, the connecting rod one (28) drives the push rod (31) to descend, the butt joint strip (39) drives the push block (34) to reset, and the clamping is released; the opening block (23) is driven by the arc-shaped slot (25) to return to the discharging station, completing the discharging of the workpiece; then the device repeats the above transmission, positioning and machining process, realizing continuous high-precision positioning and cutting operation.
