[0017] The high-frequency nut removal device disclosed in this utility model is mainly used in scenarios where existing nut removal devices cannot remove nuts in tricky positions.

[0019] Specifically, the device utilizes the position adjustment module 5 to enable the device to remove rust and adjust the angle, allowing the induction coil 3 on the device to accurately and effectively cover the nut in a tricky position. The device can use high-frequency electromagnetic induction to generate eddy currents inside the nut or bolt, causing it to heat up quickly and locally. This utilizes the difference in thermal expansion and contraction to break the rusted bond or create gaps, facilitating the rapid disassembly of stubborn nuts. This greatly improves the applicability of the device in various disassembly environments and increases the disassembly efficiency of the device.
[0020] Reference Figure 3 and Figure 4In a preferred embodiment, the bottom of the movable rod 502 has a circular hole, and a threaded rod 501 is rotatably connected to the inner wall of the circular hole via an external thread. The threaded rod 501 is rotatably connected to the opposite side of the high-frequency induction heater body 1 via a bearing, and a support frame 503 is provided on the outside of the threaded rod 501. The bottom of the support frame 503 is connected to the opposite side of the high-frequency induction heater body 1 via bolts, and the movable rod 502 is in contact with the opposite side of the support frame 503. A knob 504 is provided on the outside of the threaded rod 501, and the upper side of the knob 504 is connected to the support frame 503. The outer opposite sides of the support frame 503 are rotatably connected via bearings. A small hole is provided at the bottom of the movable rod 502, and a guide rod 507 is slidably connected within the small hole. The bottom of the guide rod 507 is bolted to the upper side of the support frame 503, and a fixing block 505 is bolted to the upper side of the threaded rod 501. An annular inclined groove 506 is provided on the fixing block 505. Two symmetrical slots are provided on the inner wall of the circular hole, and round rods are bolted to the inner walls of each slot. Limit plates 508 are rotatably connected to the outer sides of each round rod via bearings, and torsion springs 50 are provided on the outer sides of each round rod. 9. One end of each torsion spring 509 is bolted to the outside of the limiting plate 508 on the same side, and the other end is bolted to the inner wall of the slot on the same side. The outside of the limiting plate 508 is slidably connected to the outside of the threaded rod 501. Two symmetrical torsion springs 513 are provided on the outside of the rotating shaft 511. One end of each torsion spring 513 is bolted to the outside of the base 510, and the other end is bolted to the outside of the rotating seat 512. A boss is bolted to the outside of the movable rod 502, and a guide roller 515 is rotatably connected to the boss via a bearing. High-frequency induction. A boss is bolted to the outside of the heater body 1. A winding roller 514 is rotatably connected to the boss via a bearing. An anti-cutting seat 518 is bolted to the outside of the base 510. The anti-cutting seat 518 is on the same side as the winding roller 514 and the guide roller 515. A steel wire rope 516 is provided on the outside of the guide roller 515. One end of the steel wire rope 516 is bolted to the outside of the rotating seat 512, and the other end is bolted to the outside of the winding roller 514. A handle 517 is provided on the outside of the boss. The handle 517 is bolted to the side opposite to the winding roller 514.
[0021] In specific application scenarios, the position adjustment module 5 is mainly used for the position adjustment stage in the position adjustment process. Specifically, the position adjustment module 5 utilizes the threaded rod 501, movable rod 502, base 510, and rotating seat 512 to quickly and conveniently change the position of the induction coil 3, enabling the device to efficiently process the nut, thereby improving the device's versatility. The annular inclined groove 506, limiting plate 508, and torsion spring 509 allow the movable rod 502 to move to its limit distance on the threaded rod 501, at which point the limiting plate 508 adjusts the annular inclined groove 506. The locking mechanism limits the movement of the movable rod 502, preventing it from detaching from the threaded rod 501 and ensuring the device's functionality. The torsion spring 513, wire rope 516, and winding roller 514 allow for real-time adjustment of the induction coil 3's angle during operation, reducing workload and adjustment difficulty. The anti-cutting seat 518 ensures that when the rotating seat 512 rotates and resets under the torque of the torsion spring 513, it lifts the wire rope 516, preventing it from tangling with structural components and causing a tangled wire.
[0022] Reference Figure 5 In a preferred embodiment, the offset locking module 6 includes an annular frame 601 located outside the threaded rod 501. The bottom of the annular frame 601 is bolted to the side opposite to the outside of the high-frequency induction heater body 1. A spring 602 is provided on the outside of the threaded rod 501. One end of the spring 602 is bolted to the inner wall of the bottom of the annular frame 601, and the other end is bolted to a movable seat 603. The inner wall of the movable seat 603 slides against the outside of the threaded rod 501. The movable seat 603 is slidably connected to the inner wall of the annular frame 601. The annular frame 601 has two symmetrical grooves 604 on its outer side. Each groove 604 has a sliding paddle 605. The two paddles 605 are bolted to the opposite side of the movable seat 603. The bottom of the groove 604 has multiple circumferentially distributed fitting grooves 606. Each fitting groove 606 has a pin inserted into it. The pins are bolted to the opposite side of the movable seat 603.
[0023] In specific application scenarios, the offset locking module 6 is mainly used in the offset locking process. The offset locking module 6 uses the spring 602, the movable seat 603 and the pin to quickly insert into the fitting groove 606. The cutting groove 604 limits the movement of the lever 605, preventing the knob 504 from rotating. This effectively controls the rotation of the threaded rod 501 and prevents the threaded rod 501 from rotating when it is subjected to impact or vibration, thus avoiding the displacement of the induction coil 3 and ensuring the accuracy of the position of the induction coil 3 on the nut.
[0024] Working principle: When the nut to be disassembled is rusted or overtight and in a difficult position, turn knob 504. Knob 504 drives threaded rod 501 to rotate, causing movable rod 502 to extend outward on threaded rod 501. When the limiting plate 508 on movable rod 502 moves to the position of annular groove 506, the torque of limiting plate 508 drives limiting plate 508 to rotate, causing limiting plate 508 to engage in annular groove 506. Movable rod 502 then stops moving. During the movement of rod 502, the wire rope 516 connected to the rotating seat 512 pulls the winding roller 514 to rotate under the guidance of the guide roller 515, causing the winding roller 514 to continuously release the wound wire rope 516. When the induction coil 3 reaches the position of the nut, if the nut has a certain angle of deviation from the movable rod 502, the handle 517 is turned. The handle 517 drives the winding roller 514 to rotate, causing the winding roller 514 to wind up the wire rope 516, thus pulling the wire rope 516. Rotate the rotating seat 512 and overcome the torque of the torsion spring 513 to rotate it by a certain angle so that the induction coil 3 can be perpendicular to the mounting surface of the nut. Turn on the power and press the start button 4 to start the induction coil 3. The induction coil 3 uses high-frequency electromagnetic induction to generate eddy currents inside the nut or bolt, which quickly and locally heats it. After using the difference in thermal expansion and contraction to destroy the rusted joint or create a gap, use a wrench to remove the nut. When it is necessary to adjust the movable rod 502, overcome the elastic force of the spring 602 to press down the paddle 605, so that the paddle 605 drives the movable seat 603 to move down, thereby pulling the pin connected to the movable seat 603 out of the fitting groove 606, releasing the lock on the knob 504. Rotate the knob 504 to adjust the movable rod 502. After the adjustment is completed, release the movable seat 603. Under the elastic force of the spring 602, the movable seat 603 rises and returns to its original position, inserting the pin into the fitting groove 606, and completing the locking of the groove 604.
[0025] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
