One end of the movable screw rod 11 is fixedly connected to a driven gear 15. By providing a mounting base 1, a fixed plate 2, a fixed gear block 3, a drive motor 4, a drive shaft 5, a movable disk 6, a reciprocating screw rod 7, a fixed guide rail 8, a fixed rod 9, a lifting nut 10, a movable screw rod 11, a sliding nut 12, a movable clamp 13, a cylindrical gear 14, a driven gear 15 and a fixed rack 16, it is beneficial to automatically clamp and loosen the drill pipe joint, thereby improving the convenience of loading and unloading, and facilitating the rotation of the drill pipe joint after clamping, which is beneficial to continuous processing and thus improving the efficiency of drilling pipe joint processing.

[0019] Furthermore, several fixed gear blocks 3 are arranged at equal angles along the outer wall of the fixed plate 2, and the fixed plate 2 and the fixed gear blocks 3 are distributed in the shape of incomplete gears. The bottom of the reciprocating screw 7 is connected to cylindrical gears 14 distributed at equal angles along the axial center line of the movable disk 6, and two of the cylindrical gears 14 are meshed with the fixed plate 2 through the fixed gear block 3, which facilitates the rotation of the cylindrical gears 14 at different angles after being connected to the fixed gear block 3.

[0020] Furthermore, the reciprocating screw 7 is threadedly connected to the lifting nut 10, and the lifting nut 10 is slidingly connected to the fixed guide rail 8, and the fixed guide rail 8 is distributed in a "concave" shape, and the fixed guide rail 8 is symmetrically distributed on both sides of the lifting nut 10, which facilitates driving the lifting nut 10 to rise and fall.

[0021] Furthermore, both ends of the sliding nut 12 are distributed in a "concave" shape, and the movable clamp 13 is rotatably connected to the sliding nut 12 through an axis. A through groove is provided at the middle end of the movable clamp 13, and the movable clamp 13 is slidably connected to the fixed rod 9 through the through groove, and one end of the movable clamp 13 is semicircular, which facilitates driving the movable clamp 13 to clamp or loosen.

[0022] Furthermore, the driven gear 15 is meshed with the fixed rack 16 , and the driven gear 15 and the fixed rack 16 form a sliding structure, which facilitates driving the movable screw rod 11 to rotate.

[0023] When in use, first fix the mounting base 1 to the processing table through external bolts, then start the driving motor 4, so that the driving motor 4 drives the movable disk 6 to rotate through the driving shaft 5, so that the movable disk 6 drives the cylindrical gear 14 to revolve through the reciprocating screw 7.

[0024] At the same time, the other cylindrical gear 14 gradually moves away from the fixed gear block 3, so that through the above principle, the other cylindrical gear 14 continues to drive the other reciprocating screw 7 to rotate, and then the other reciprocating screw 7 drives the lifting nut 10 to rise, and through the reverse operation of the above principle, the other set of movable clamps 13 move away from each other to loosen the oil drill pipe joint, thereby completing the automatic unloading work, further improving the convenience of operation. At the same time, the remaining cylindrical gear 14 is not connected to the fixed gear block 3, so that the remaining movable clamps 13 maintain the clamping and positioning work of the oil drill pipe joint, thereby facilitating the continuous processing after the oil drill pipe joint is rotated to a certain angle, effectively improving the processing efficiency.
