Referring to fig. 10, the invention further discloses a control method of the tracking type telescopic automatic chip removal system based on the numerically controlled lathe, which specifically comprises the following steps:

step one, preparation before processing: after the workpieces are assembled, if the machined workpieces generate chips, the folded plastic chip collecting barrel 32 is pulled out, if the strip-shaped chips are generated, the chips are not pulled out, then the U-shaped frame 21 of the tracking chip blowing device 2 is grasped, the square shaft 26 is pulled out, then the U-shaped frame 21 is rotated to be in a vertical state, then the U-shaped frame 26 is inserted into the square shaft 26 for fixing, the bolt on the U-shaped frame 21 is loosened, the angle of the chip blowing mechanism 22 can be adjusted by rotating, the chip blowing mechanism faces to the position of the workpieces, and then the bolt is tightened;

step two, the adaptability of the adjustable scrap blowing mechanism 22 is adjusted: the multiple fan-shaped air blowing openings 222 of the adjustable chip blowing mechanism 22 are initially in a furled state and are adapted to short workpieces, if the workpieces are slender workpieces, the motor 228 is started to drive the winding wheel on the winding wheel to wind the pull rope 229, and then the two fan-shaped air blowing openings 222 are pulled towards two sides through the lantern ring 226 to be separated, and finally the multiple fan-shaped air blowing openings 222 are pulled to be in a parallel state;

step three, tracking the work of the chip blowing device 2: the tracking chip blowing device 2 is controlled by the control system to start, the camera 223 shoots pictures at the workpiece, then data processing is carried out on an external computer, the cutter is positioned in a visual contrast detection mode, the first linear guide rail 24 is controlled to work, and the U-shaped frame 21 and the adjustable chip blowing mechanism 22 are driven to synchronously move to blow chips when the cutter moves; when scrap is blown, the air pump 6 works, air is filled into the connecting box 2211 through the inflation main pipe 7, the air is dispersed into the fan-shaped air blowing openings 222 through the inflation hose 2210 to be blown out towards the right, and scrap generated by workpiece machining is blown out towards the right;

step four, the debris collection component 3 collects debris: after being blown rightwards by the tracking chip blowing device 2, chips generated by processing directly fall into the folding plastic chip collecting barrel 32 under the blockage of the right wall of the lathe frame 1, meanwhile, the air pump 6 extracts air in the folding plastic chip collecting barrel 32 through the exhaust pipe 5, so that a feed port at the top of the folding plastic chip collecting barrel 32 generates suction force, the chips falling to the vicinity of the outer side of the feed port are sucked into the feed port and then pass through the long groove 36 of the V-shaped flexible rubber plate 35, the extracted air is filtered through the matching of the filter cover 37 and the elastic wire 38, the chips are remained in the folding plastic chip collecting barrel 32, the rotating door 31 is pulled rightwards after the processing is finished, and then the folding plastic chip collecting barrel 32 is pulled out to clean internal impurities;

step five, winding ribbon-shaped scraps: the tracking chip blowing device 2 and the tracking chip rolling device 4 are started, the second linear guide rail 41 and the first linear guide rail 24 work synchronously, the tracking chip blowing device 2 blows ribbon-shaped scraps rightwards to enable the ribbon-shaped scraps to fall onto the tracking chip rolling device 4, the ribbon-shaped scraps are put on the insulating roller 415 and the winding roller 48, the starting motor 46 drives the first rotating disc 47, the winding roller 48 and the second rotating disc 49 to integrally rotate, the ribbon-shaped scraps are hooked by the hanging rod 410 and then wound up, after the redundant ribbon-shaped scraps are wound up, the ribbon-shaped scraps are straightened, and further left pressure is generated on the winding roller 48, the rotating arm 413 deflects leftwards until the metal strips 416 on the first rotating disc 47 and the second rotating disc 49 contact the metal elastic sheet 417 on the first iron core 412, related circuits are conducted, and further the power supply of the motor 46 is cut off by triggering electric signals, the winding is stopped, and when the ribbon-shaped scraps are loosened again, the rotating arm 413 is reset, and then the motor 46 is started again to wind;

step six, cleaning ribbon-shaped scraps: when the winding is finished and the cleaning is needed, the bolt for fixing the motor base 43 is detached, the motor base 43 slides forwards, the first rotating disc 47 is separated from the winding drum 48, then the wound ribbon-shaped scraps can be directly taken down from the front side, and finally the motor base 43 and the first rotating disc 47 are reset and fixed.
