10. The use method of the pipe inner wall cleaning device for nodular cast iron according to any one of claims 1 to 9 is characterized in that: the method comprises the following steps:
(A) positioning the pipe fitting: the pipe fitting to be cleaned is flatly placed on the two fixed jackets 13, the screw rods 19 are rotated, the thread turning directions of the two ends of each screw rod 19 are opposite, the movable jackets 15 on the two sides of each fixed jacket 13 can be driven to be far away from the fixed jackets 13, at the moment, the movable jackets 15 pull one ends of the movable rods 18 to be far away from the ejector rods 14, the other ends of the movable rods 18 pull the ejector rods 14 to move towards the inner sides of the fixed jackets 13, so that the clamp blocks 17 at one ends of the ejector rods 14 extrude and clamp the pipe fitting, and meanwhile, the ejector rods 14 are driven by the movable jackets 15 and the movable rods 18 to synchronously move, so that the center of the pipe fitting is superposed with the central axis of the fixed jackets 13;
(B) and adjusting the rotating shaft: a hand crank 25 drives the screw rod 24 through a bevel gear, so that the sliding table 4 slides along the screw rod 24 to a direction close to the bracket 2, and one end of the rotating shaft 3 close to the baffle is inserted into the limiting hole 21;
(C) and folding in the fixing strip: along with the insertion of the rotating shaft 3, one end of the fixing strip 5, which is close to the baffle, abuts against the surface of the baffle 20 and is supported by the two supporting rods 10, the sliding block 9 at the other end of each supporting rod 10 is under the elastic action of the springs 11, the elastic forces of the two springs 11 are offset, the fixing strip 5 is located at the outermost end, along with the continuous movement of the sliding table 4, the fixing strip 5 is pushed by the baffle 20 to move towards the direction of the motor 22, the fixing strip 5 is connected with the rotating shaft 3 through the two connecting rods 7 which are arranged in parallel, along with the horizontal movement of the fixing strip 5, the connecting rods 7 rotate to drive the fixing strip 5 to approach towards the direction of the rotating shaft 3 until being collected into the fixing groove 6, at the moment, the sliding block 9 slides along the sliding groove 8, so that the two springs 11 are compressed and stretched respectively, the elastic forces of the two springs 11 are not offset, and the fixing strip 5 is subjected to outward thrust;
(D) adjusting the fixing strip: with the continuous movement of the sliding table 4, the fixing strips 5 and the rotating shaft 3 penetrate through the limiting holes 21 to enter the pipe fitting, when the fixing strips 5 are completely inserted into the pipe fitting, the two fixing strips 5 can be rapidly ejected out under the action of the two springs 11 to be separated from the fixing groove 6, so that the abrasive cloth on the outer wall of each fixing strip 5 is pressed in the pipe fitting;
(E) cleaning the pipe fittings: starter motor 22, motor 22 output shaft rotate and drive pivot 3 and rotate, and then drive the emery cloth of 5 outer walls of fixed strip and rotate the clearance to the pipe fitting inner wall, and after the clearance was accomplished, the counter rotation crank 25 makes slip table 4 slide to the direction of keeping away from support 2, and then makes fixed strip 5 leave inside the pipe fitting, expandes once more and resets to accomplish the clearance process of pipe fitting.
