the servo motor 355 is started to drive the second-stage lead screw 354 to rotate, the second-stage sliding blocks 351 are in spiral transmission connection with the second-stage lead screw 354, the thread directions of the left part and the right part of the second-stage lead screw 354 located inside the second-stage sliding groove 35 are opposite, so that the two second-stage sliding blocks 351 are driven to move oppositely along the second-stage sliding groove 35, the two detection plates 31 are driven to approach each other until the insertion plate 313 on the left detection plate 31 is inserted into the insertion groove 314 on the right detection plate 31, splicing of the two detection plates 31 is completed, the stability between the detection plates 31 can be improved due to the matching of the insertion plate 313 and the insertion groove 314, and the normal operation of the second-stage detection mechanism 3 is guaranteed;
in the process that the left detection plate 31 and the right detection plate 31 approach each other, the movable rod 341 contacts the left end of the sink roller first, the left end of the movable rod 341 is extruded into the sleeve 34 for a certain distance along with the completion of splicing of the two detection plates 31, then the band-type brake motor 33 is started to drive the gear 332 to rotate clockwise, the gear 332 is meshed with the gear teeth 311 on the outer annular surfaces of the two detection plates 31, the two detection plates 31 are spliced into an annular structure, the two tracks 312 are also spliced into an annular structure, the roller 333 is rotatably connected with the tracks 312, the center position of the front side surface of the roller 333 is fixedly connected with the fixed plate 331 through the fixed shaft, so that the fixed plate 331 is driven to do circular motion around the sink roller, the movable rod 341 is driven to do circular motion around the sink roller, and the right end of the movable rod 341 is in a hemispherical structure, when the movable rod 341 passes through the upper end of the sinking roller, the upper end of the sinking roller is thinned after turning, so that the movable rod 341 extends under the action of a spring, and the touch pen 342 at the left end of the movable rod is driven to slide towards the center of the sinking roller along the movable groove 343, so that the touch pen 342 leaves a motion track on the electronic whiteboard 32, after the movable rod 341 leaves the light position on the upper side of the sinking roller, the movable rod 341 is pressed again to contract, after one rotation, a complete motion track is left on the electronic whiteboard 32, the distance of the downward concave track is read through the scale mark 321 carved on the vertical part on the upper side of the left electronic whiteboard 32, and the turned amount is judged by combining the shape of the track, so that the position of the counterweight is determined, and the working efficiency is improved;
after the sink roll passes through the welding counter weight, it is rotatory to start step motor 22 and start one-level band pulley 221, because one-level band pulley 221 passes through the belt rotation with second grade band pulley 232 and is connected, thereby it is rotatory to drive cutting ferrule 23, and then it is rotatory to drive the sink roll, drive the sink roll through step motor 22 and stop the back to the optional position, rotating threaded rod 241 drives splint 24 and keeps away from each other, thereby make the sink roll lose fixedly, observe whether the sink roll takes place to rotate, and then judge whether the sink roll reaches dynamic balance, and the work efficiency is improved.
