[0002] As the core connection component in prestressed concrete structures, anchors are mainly used to permanently fix prestressed tendons such as steel strands and steel bars, and to improve the bearing capacity, crack resistance and durability of the structure by applying prestress. With the rapid growth of demand for infrastructure construction such as modern bridges, high-rise buildings, mine support and rail transit, anchor processing technology has become an indispensable key link in the field of civil engineering.

[0003] Anchor chamfering is a key process in the manufacture of prestressed anchors, which directly affects the assembly accuracy of anchors and prestressed tendons. In prestressed concrete structures, anchors need to work closely with high-strength materials such as steel strands and threaded steel bars, and end burrs, sharp edges or dimensional deviations may lead to stress concentration, insufficient grip and even fatigue cracking. Especially in high humidity or corrosive environments such as bridges and marine engineering, surface defects will accelerate the rust failure of anchors and threaten structural safety.

[0054] Working principle: When this device is in use, the sight 70 to be processed is placed at one end of the conveying structure 10 away from the detection mechanism 40. Then, the conveyor belt in the conveying structure 10 drives the sight 70 to move. When the sight 70 moves below the grinding part 20, the fourth electric cylinder 231 drives the second connecting plate 232, which in turn drives the first centering plate 234 to move downward. There are two limit rods below the first centering plate 234. The fifth electric cylinder 233 drives the first centering plate 234 to center the sight 70 directly below the first electromagnet 224, facilitating the energization and adsorption of the first electromagnet 224. The third electric cylinder 221 drives the first Z-shaped plate 222, which in turn drives the second drive motor 223 and the first electromagnet 224 to move downward. The first electromagnet 224 is energized to adsorb the sight 70. The second drive motor 223 drives the first electromagnet 224 to drive the sight 70 to rotate. Then, the first electric cylinder 211 drives the grinding wheel 215 close to the sight 70. The second electric cylinder 214 adjusts the distance between the two grinding wheels 215 to grind the sight 70. After grinding, the grinding structure 21 places the ground sight 70 on the conveying structure 10, and the conveying structure 10 continues to transport the sight 70. When the conveying structure 10 transports the sight 70 directly below the punching part 30, the seventh electric cylinder 322 extends and retracts to drive the connecting frame 321 to move downward. The sixth electric cylinder 313 extends to drive twelve racks 312 to clamp the sight 70. The first servo motor 331 drives the third gear 332 to drive the second internal gear ring 333 to rotate. The second internal gear ring 333 drives the outer ring 351 to drive the third internal gear ring 352 or the fourth internal gear ring 353 to rotate, which in turn drives the fifth gear 357 to drive the first drill bit 354 to rotate to complete punching. At the same time, the second servo motor 361 drives the second drill bit 362 for drilling.

[0055] When the distance of the side holes needs to be adjusted, the third servo motor 358 drives the fourth gear 355 to rotate, which in turn drives the driving inner ring 359 to rotate. The driving inner ring 359 drives another fourth gear 355 to rotate. One third servo motor 358 drives all the fourth gears 355 to rotate. The fourth gear 355 drives the drill bit mounting bracket 356 to drive the first drill bit 354 to rotate, so that all the first drill bits 354 rotate inward by an angle, causing the fifth gear 357 to disengage from the third internal gear ring 352. Then, the ninth electric cylinder 38 drives the outer ring 351 to move toward the conveying structure 10 direction, causing the fourth internal gear ring 353 to mesh with the fifth gear 357, thereby realizing the inward movement of the first drill bit 354 and adjusting the hole distance on the sight 70. After the holes are drilled, the fixing structure 31 places the sight 70 on the conveying structure 10. The conveying structure 10 transports the sight 70 to the lower part of the detection mechanism 40. The electric cylinder of the centering bottom plate 431 drives the second centering plate 432 to correct the sight 70 directly below the second magnet 424. The sixth driving motor 423 drives the second magnet 424 to drive the sight 70 to rotate. At this time, the detection sensor 44 detects the sight 70. After the detection, the second magnet 424 places the sight 70 on the conveying structure 10. When the sight 70 is qualified, the steering gear 411 does not drive the toggle lever 412 to rotate, and the sight 70 is conveyed out through the first conveying port 13; when the sight 70 is unqualified, the steering gear 411 drives the toggle lever 412 to rotate, pushes the sight 70 to the second conveying port 14, and the second conveying port 14 conveys the sight 70 into the detection mechanism 40.
