[0029] The shock absorber 2.4 can absorb the inertia of the steel pipe 4 rotation, further ensuring the quality of the steel pipe threading.

[0030] Working principle:

[0031] The V-shaped wheel 1.1 descends: under the action of the rightward pulling force, the pull rod 1.2 drives the swing arm 1.7 to rotate counterclockwise, the upper end of the swing arm 1.7 pulls the lifting shaft 1.4 downward, and the lifting shaft 1.4 drives the V-shaped wheel 1.1 downward, and finally the V-shaped wheel 1.1 is lowered a required distance.

[0032] The V-shaped wheel 1.1 rises: under the action of the leftward thrust, the pull rod 1.2 drives the swing arm 1.7 to rotate clockwise, the upper end of the swing arm 1.7 pushes the lifting shaft 1.4 to rise, and the lifting shaft 1.4 drives the V-shaped wheel 1.1 to rise, and finally the V-shaped wheel 1.1 rises the required distance.

[0033] The rotating wheel 2.1 rises: the piston of the oil cylinder 2.5 is pushed out, and the first base 2.3 is separated from the top of the frame 3 until the rotating wheel 2.1 contacts the bottom of the steel pipe 4; at the same time, the piston of the air cylinder 2.8 is also pushed out in cooperation with the oil cylinder 2.5, and the rotating part 2.9 rotates counterclockwise until the holding roller 2.10 contacts the side of the steel pipe 4. Under the action of the holding roller 2.10, the steel pipe 4 will not move, thereby ensuring the quality of threading.

[0034] The rotating wheel 2.1 descends: the piston of the oil cylinder 2.5 retracts until the second base 2.3 abuts against the top of the frame 3, the oil cylinder 2.5 stops working, and at the same time the piston of the air cylinder 2.8 retracts, the rotating member 2.9 rotates clockwise, and the holding roller 2.10 is separated from the steel pipe 4.

[0035] The present invention provides a threading machine auxiliary machine, wherein the feed roller has a lifting function in addition to the basic feeding function, thereby meeting the special needs of users; the rotating roller has a lifting function in addition to the basic function of rotating the workpiece, thereby adjusting the height of the two rotating wheels 2.1 to adapt to steel pipes of different specifications by lifting and lowering the oil cylinder 2.5; and the holding roller 2.10 can also prevent the workpiece from moving, thereby meeting the special needs of users.

[0036] In the above embodiments, the present invention is only exemplarily described, but those skilled in the art may make various modifications to the present invention without departing from the spirit and scope of the present invention after reading this patent application.
