When the electric screw 301 rotates and causes the screw sleeve 302 to rotate, the screw sleeve 302 and the retracted connecting plate 303 first rotate and then lock, so that the screw sleeve 302 can finally move on the electric screw 301.

[0032] Working principle: Before using this positioning mechanism for gantry deep hole drilling machine, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 6 As shown, firstly, the workpiece is placed on the surface of the processing table 201, and then the motor 203 is started to rotate the turntable 202, so that the slider 205 drives the lifting block 208 to move toward the workpiece along the slide groove 206. As the edge of the workpiece fits and presses the abutment plate 210, the workpiece will cause the abutment plate 210 to slide. As the abutment plate 210 slides, the sliding plate 209 will slide upward due to the pressing, so that the other end of the sliding plate 209 extends out of the surface of the lifting block 208 and lifts the workpiece upward. When the workpiece is pushed to the middle position of the processing table 201 and clamped, the whole workpiece will be lifted to a certain height by the lifting blocks 208 around it, so as to avoid seamless fitting between the workpiece and the surface of the processing table 201, so that the processing table 201 is accidentally touched by the drill bit for processing the through hole, resulting in damage, thereby reducing the wear of the drill bit;

[0033] After the processing is completed, the motor 203 is reversed, so that the slider 205 is reset. During this process, the workpiece no longer presses against the abutment plate 210, and the sliding plate 209 slides down due to its own weight and presses the abutment plate 210 to reset.

[0034] The first electric telescopic rod 212 is activated so that the support plate 213 pushes the workpiece to lift, and then the second electric telescopic rod 214 is activated so that the workpiece is pushed and slid to the side of the processing table 201 to avoid the lifting block 208 hindering the transfer of the workpiece;

[0035] Then, the transport roller is started to transport the workpiece away from the bed frame 102 from the side, and the electromagnetic tube 305 is magnetized. At this time, the connecting shaft 304 will drop due to the magnetic force between the electromagnetic tube 305 and the workpiece, so that the electromagnetic tube 305 and the workpiece are magnetically attracted together by the magnetic force, and as the workpiece moves, the metal debris on the surface of the workpiece will be attracted to the electromagnetic tube 305;

[0036] After the workpiece leaves, the electric screw 301 is started, so that the screw sleeve 302 drags the telescopic connecting plate 303 to drive the scraper sleeve 309 to slide on the electromagnetic tube 305, so that the debris on the electromagnetic tube 305 will be scraped to both sides, and finally the magnetization of the electromagnetic tube 305 is canceled, so that the metal debris at both ends of the electromagnetic tube 305 all fall into the storage chamber 310, so that the metal debris remaining on the surface of the workpiece can be cleaned again.
