Description

Technical Field

[0001] The invention relates to the technical field of stress wave driving tools, in particular to a stress wave driving tool and a method for quickly disassembling interference screw structure fasteners. Background Art

[0002] When fasteners are overlapped with two composite laminates or titanium alloy plates for aviation, interference connection is generally used, also called interference fit assembly or interference extrusion installation. The interference is the fit between the interference fit of the bolt and the hole of the connecting plate, and the diameter of the light rod is slightly larger than the hole. For traditional pneumatic loading methods, the general interference amount of metal interference installation is 0.05%-1.5%, and the general interference amount of composite material installation is 0.05%-1.2%. The interference amount is the percentage of the difference between the hole diameter and the light rod diameter and the light rod diameter. Rapid mechanical impact loading (such as stress wave impact, etc.) can realize the interference installation of the light rod part of the high-locking bolt on the two overlapping plates, and the maximum interference amount of the interference installation can reach 2.5%. After the impact loading is completed, the broken cap nut dedicated to the high-locking bolt is used to tighten it on the high-locking bolt from the other side. When a certain tightening torque is reached, the collar breaks from the groove, and the threaded nut stays on the high-locking bolt to achieve the function of locking and anti-slipping. When tightening the nut, in order to prevent the bolt from rotating due to excessive torque, you can use the corresponding wrench to insert it into the multi-faceted hole at one end of the high-locking bolt near the threaded part. During maintenance and disassembly, the current method is to use a wind tunnel rivet gun to disassemble. You need to first force the fastening nut of the high-locking bolt to be removed, then aim the gun head at the fastener, and use the top iron of the wind tunnel rivet gun to aim at the high-locking bolt for repeated pneumatic loading to remove the high-locking bolt from the screw hole.

[0003] At present, although high-locking bolts can be pushed out by using wind tunnel rivet guns, repeated impacts will aggravate the damage to the connection hole wall and expand the damaged area to the surrounding areas. This will inevitably require the expansion of a larger damaged hole, thereby weakening the load-bearing and load-transmitting capacity of the connecting plate. In addition, a separate device must be used to remove the nut, which slows down the disassembly speed. Summary of the invention

[0021] The present invention also provides a method for quickly disassembling an interference threaded structural fastener, comprising the following steps:

[0022] Step 1: Install the impact head on the push rod, insert the sleeve into the sleeve and fix it to one end of the cross pipe with bolts;

[0023] Step 2: insert the polygonal column on the impact head into the polygonal hole at one end of the high-locking bolt.

[0027] (III) Beneficial effects

[0028] Compared with the prior art, the present invention provides a stress wave driven tool and method for rapid disassembly of interference screw structure fasteners, which has the following beneficial effects:

[0029] 1. The present invention can remove the nut on the high-locking bolt, and at the same time, the thrust ring on the impact head blocks the nut of the high-locking bolt to make it fall off from the sleeve until the nut to be removed is completely removed. After removal, the next high-locking bolt can be removed, and the limit assembly is used to lock the cross tube and the sleeve. Then, the impact head is inserted into the multi-faceted hole on the high-locking bolt, and then the loading mechanism is started. The magnetic stress wave generated by the induction coil and the loading coil is used to make the impact head hit the screw of the high-locking bolt, so that the screw falls off from the screw connection hole until all the screws to be removed are removed. The motor is started to rotate the screw rod, and when the screw rod rotates, the internal thread block is driven to move the rectangular rod. When the rectangular rod moves, the arc rod is driven to contact the structural member, and the stress wave driving tool is auxiliary supported to improve the stability when removing the high-locking bolt.

[0030] 2. The disassembly mechanism provided in the present invention, when in use, turns on the first switch to energize the electromagnetic coil to generate a magnetic pole opposite to one side of the strong magnetic ring, and the magnetic attraction attracts the strong magnetic ring to make the cross tube and the sleeve move at high speed and hit the nut of the high locking bolt. At this time, under the dead weight of the strong magnetic ring and the cross tube, the inertial potential energy generated enables the sleeve to be inserted into the nut, and the friction between the sleeve and the nut can be increased. Then the main switch is turned on to make the drive motor work to drive the worm to rotate, and when the worm rotates, it drives the worm wheel to rotate the shaft and the gear When the gear rotates, it drives the gear ring to rotate the sleeve. When the sleeve rotates, the nut of the high-locking bolt is loosened on the screw rod through the protrusion and the slot. In this way, the nut of the high-locking bolt can be forced to be removed. After all the nuts are removed, the brake pad is moved by hand to make the rotating shaft drive the limit block to rotate. When the limit block rotates, it moves to the limit groove on the limit ring. At this time, the cross tube can be limited so that the cross tube and the sleeve cannot move, thereby achieving the locking effect and avoiding the cross tube from sliding when the loading mechanism is working.

[0031] 3. The loading mechanism provided in the present invention, when in use, starts the second switch, so that the induction coil and the loading coil are energized at the same time, when energized, the opposite ends of the induction coil and the loading coil generate the same magnetic pole, at this time the magnetic repulsion force increases instantly, and at the same time the second switch also controls the operation of the steering gear, the operation of the steering gear drives the rocker arm so that the shaft pin drives the square frame to move, the movement of the square frame drives the sliding sleeve to make the rectangular block subject to force, the rectangular block drives the pull rod to move the lock tongue, and the lock tongue releases the lock on the cylinder after it moves. Since a certain amount of time is required during the movement of the steering gear, the magnetic repulsion force can be increased to the maximum and then released instantly, so that energy storage can be achieved, so that the fixed frame, the counterweight block and the induction coil It can accumulate energy before moving, and the magnetic repulsion can continue to load the counterweight and the induction coil during the movement, so that when the fixed frame hits the brake plate, the push rod and the impact head can have sufficient kinetic energy to hit the screw of the high-locking bolt, so that the screw can fall off from the screw hole. The induction coil and the loading coil are controlled by the second switch to produce opposite magnetic poles. The induction coil, the counterweight and the fixed frame can be reset by magnetic attraction. At the same time, the magnetic attraction generated can also attract the magnetic block to reset the push rod and the impact head. In addition, when the polygonal column on the impact head is inserted into the polygonal hole on the high-locking bolt, the push rod and the impact head can also be reset.

A sleeve 38 is provided at the pipe mouth of one end of the sleeve 6, and a disassembly mechanism is provided on the tube wall of the sleeve 6. The disassembly mechanism drives the sleeve 6 through a reduction mechanism so that the sleeve 38 disassembles the nut of the high locking bolt. A cross tube 31 is sleeved in the sleeve 6, one end of the cross tube 31 is fixedly connected to the sleeve 38, and the other end of the cross tube 31 extends into the shell 1 and is installed with a driving component.

[0047] The shell 1 is fixed on one side of the second connecting seat 2, and a plurality of guide rails 25 are fixedly connected inside the shell 1. A guide frame 23 is slidably connected between the plurality of guide rails 25. A loading mechanism is installed inside the guide frame 23. The loading mechanism is installed in the cross tube 31 and is installed with an impact head 17. The loading mechanism generates a magnetic stress wave to cause the impact head 17 to hit the screw of the high-locking bolt, causing the screw to fall off from the screw hole.

[0048] An extension portion 5 is provided on one side of the first connecting seat 4, and a sleeve 6 is sleeved in the extension portion 5. A rectangular sleeve 10 is fixedly connected to the lower end of the extension portion 5, and a rectangular rod 11 is provided in the rectangular sleeve 10. The rod wall of the rectangular rod 11 is provided with a bending portion. A rectangular tube 34 is fixedly connected to one side of the housing 3. One end of the rectangular rod 11 penetrates the side wall of the housing 3 and extends into the rectangular tube 34. An internal thread block 56 is fixedly connected in the rectangular tube 34. A screw rod 55 is threadedly connected in the internal thread block 56.

[0049] When in use, the impact head 17 is installed on the push rod 16, and the sleeve 38 is inserted into the sleeve 6 and fixed to one end of the cross tube 31 with bolts. The inner diameter of the sleeve 38 can be configured into a variety of sizes according to actual needs to adapt to the nuts of high-locking bolts with different diameters; the polygonal column on the impact head 17 is inserted into the polygonal hole at one end of the high-locking bolt. When the polygonal column is inserted into the polygonal hole, the rotation of the screw can be limited when the nut is removed, so as to avoid the rotation and inability to remove the nut. The size and structure of the polygonal column are designed according to the polygonal hole designed at the end of the high-locking bolt standard part. The existing high-locking bolt has a protruding part at the tail of the high-locking bolt (the protruding part designed at the bare rod part of the high-locking bolt). A multi-faceted hole is designed for the head. When tightening the nut, a wrench of the same size and structure is inserted into the multi-faceted hole to assist in adding force, which can prevent the high-lock bolt from rotating when tightening the nut. In addition, the multi-faceted hole is a groove with multiple edges such as a pentagonal groove or a hexagonal groove conventionally set on the high-lock bolt. Similarly, the multi-faceted column structure of the main component in the technical solution needs to be designed according to the multi-faceted hole structure and size on the high-lock bolt in the prior art. Therefore, only by configuring multi-faceted columns of various sizes and structures, the multi-faceted column can be replaced according to needs when removing the nut. After starting the drive assembly, the electromagnetic coil 32 generates a magnetic attraction to attract the strong magnetic ring 30, and the strong magnetic ring 30 moves The cross tube 31 is moved to push the sleeve 38 to move, and the sleeve 38 hits the nut of the high-locking bolt. At this time, the triangular block 40 in the sleeve 38 uses its edge to cut a pit on the nut. After cutting the pit, the friction between the sleeve 38 and the nut is increased to avoid the nut being unable to be screwed when the torque increases. At the same time, the nut can be vibrated during the collision to make it easier to loosen. The disassembly mechanism is started, and the reduction mechanism is used to drive the sleeve 6 to generate a torsional force on the sleeve 38. The nut of the high-locking bolt is disassembled by using the sleeve 6 and the sleeve 38 with low speed and high torque. After the disassembly is completed, the impact head 17 is removed from the high-locking bolt, the drive assembly is reset manually, and the electromagnetic coil 32 is used to generate The same magnetic pole as that on one side of the strong magnetic ring 30 uses magnetic repulsion to make the cross tube 31 push the sleeve 38 to reset. During the reset, the thrust ring on the impact head 17 blocks the nut of the high-locking bolt and makes it fall off from the sleeve 38 until the nut to be removed is completely removed. After removal, the next high-locking bolt can be removed. The limit assembly is used to lock the cross tube 31 and the sleeve 38, and then the impact head 17 is inserted into the multi-faceted hole on the high-locking bolt. Then the loading mechanism is started, and the magnetic stress wave generated by the induction coil 20 and the loading coil 21 is used to make the impact head 17 hit the screw of the high-locking bolt, so that the screw falls off from the screw connection hole until all the screws to be removed are removed.

[0050] When in use, the motor 19 is started to rotate the screw rod 55, and the rotation of the screw rod 55 drives the internal thread block 56 to move the rectangular rod 11, and the movement of the rectangular rod 11 drives the arc rod 8 to contact the structural member, thereby providing auxiliary support for the stress wave drive tool, improving the stability when removing the high-locking bolts, and avoiding uneven force on the high-locking bolts due to multiple loading, which aggravates the damage to the wall of the connecting hole and expands the damaged area to the surrounding areas.

[0055] The disassembly mechanism provided in the present invention, when in use, turns on the first switch 12 to energize the electromagnetic coil 32 to generate a magnetic pole opposite to one side of the strong magnetic ring 30, and the magnetic attraction attracts the strong magnetic ring 30 to make the cross tube 31 and the sleeve 38 move at high speed and hit the nut of the high locking bolt. At this time, under the dead weight of the strong magnetic ring 30 and the cross tube 31, the inertial potential energy generated enables the sleeve 38 to be inserted into the nut, and the friction between the sleeve 38 and the nut can be increased. Then, the main switch 18 is started to make the drive motor 1913 work to drive the worm 33 to rotate. When the worm 33 rotates, it drives the worm wheel 37 to rotate the shaft and the gear 35. When the gear 35 rotates, it drives The movable gear ring 36 rotates the sleeve 6. When the sleeve 6 rotates, the convexity and the groove cooperate with the driving sleeve 38 to drive the nut of the high-locking bolt to loosen on the screw rod. In this way, the nut of the high-locking bolt can be forced to be removed. After all the nuts are removed, the brake pad is moved by hand to make the rotating shaft 42 drive the limit block 43 to rotate. When the limit block 43 rotates, it moves to the limit groove on the limit ring 41. At this time, the cross tube 31 can be limited, so that the cross tube 31 and the sleeve 38 cannot move, thereby achieving the locking effect, avoiding the sliding of the cross tube 31 when the loading mechanism is working, causing irreversible mechanical damage to the connecting hole wall of the high-locking bolt and the connecting plate.

[0056] Embodiment 3: Based on embodiment 1, the difference is that;

[0057] See attached Figure 2 , Figure 3 , Figure 8-Figure 11The loading mechanism includes a push rod 16, which is sleeved in the cross tube 31 and fixedly connected with an annular block. One end of the cross tube 31 is provided with a flared portion that matches the annular block. A support frame 29 is sleeved on the rod wall of the push rod 16, and the support frame 29 is fixed in the shell 1. One end of the push rod 16 is connected to the impact head 17, and the other end of the push rod 16 is fixedly connected with a brake plate 28. The side wall of the brake plate 28 is fixedly connected with a plurality of magnetic blocks 26. The four corners of the brake plate 28 are slidably connected with a plurality of guide rails 25 through slide grooves. The guide frame 23 is fixedly connected with an induction coil 20 and a counterweight block. The shell 1 is fixedly connected with a loading coil 21. The shell 1 is fixedly connected with two conductive copper bars 24. The two power input ends of the induction coil 20 are fixedly connected with carbon brushes 46, and the carbon brushes 46 are in contact with the conductive copper bars 24. A fixed frame 22 is arranged between the induction coil 20 and the loading coil 21. The fixed frame 22 is fixed in the shell 1 and is installed with a power storage component for delaying the movement of the induction coil 20.

[0058] The loading mechanism also needs to be equipped with an input power supply, a step-up transformer, a rectifier element, a current-limiting resistor, and a capacitor. When in use, it is only necessary to charge the capacitor through the input power supply after the step-up transformer boosts the voltage and the rectifier element rectifies it. After the specified voltage is reached, the discharge switch is closed and the loading coil 21 is discharged through the cable. The electromagnetic repulsion generated between the loading coil 21 and the induction coil 20 is used to provide kinetic energy to the induction coil 20 and the counterweight, thereby forming a millisecond-level impact loading. Through the movement of the impact head 17, the high-locking bolt can be pushed out of the screw hole on the lap plate. When the loading coil 21 and the induction coil 20 generate electromagnetic attraction, the loading mechanism can be reset.

[0059] The power storage component includes a cylinder 45, which is fixed to one side of the guide frame 23 and has a rectangular hole. A locking tongue 52 is arranged in the rectangular hole. One end of the locking tongue 52 is fixedly connected to a pull rod 51. Two rectangular blocks 53 are fixedly connected to the rod wall of the pull rod 51. A sliding sleeve 49 is sleeved on the rod wall of the pull rod 51. Two strip holes are arranged on the side wall of the sliding sleeve 49. The rectangular block 53 is slidably connected in the strip hole. A second spring 50 is fixed in the sliding sleeve 49. One end of the second spring 50 contacts one end of the pull rod 51. A steering gear is fixedly connected in the housing 1. The output end of the steering gear is fixedly connected to a rocker arm 47. One end of the arm 47 is fixedly connected to a pin shaft, a square frame 48 is sleeved on the shaft wall of the pin shaft, the square frame 48 is fixed to one end of a sliding sleeve 49, one side of the fixed frame 22 is fixedly connected to a directional sleeve, the sliding sleeve 49 is slidably connected in the directional sleeve, one side of the fixed frame 22 is sleeved with a locking tongue 52 through a square hole, one side of the cylinder 45 is provided with a chamfer, and an inclined surface is provided at the corner of one end of the locking tongue 52. The brake plate 28 and the guide frame 23 are fixedly connected to the opposite side with a rubber block 27, and a plurality of through grooves are provided on one side of the rubber block 27. One side of the shell 1 is fixedly connected to an end cover by bolts, and an air hole is opened on the side wall of the end cover.

[0060] The loading mechanism provided in the present invention, when in use, starts the second switch 15, so that the induction coil 20 and the loading coil 21 are energized at the same time, when the induction coil 20 and the loading coil 21 are energized, the same magnetic poles are generated at the opposite ends of the induction coil 20 and the loading coil 21, and the magnetic repulsion force increases instantly. At the same time, the second switch 15 also controls the operation of the steering gear, and the operation of the steering gear drives the rocker arm 47 so that the shaft pin drives the square frame 48 to move, and the movement of the square frame 48 drives the sliding sleeve 49 to force the rectangular block 53, and the rectangular block 53 drives the pull rod 51 to move the lock tongue 52, and the lock tongue 52 releases the lock of the cylinder 45 after it moves. Since a certain amount of time is required during the movement of the steering gear, the magnetic repulsion force can be increased to the maximum and then released instantly, so that energy storage can be achieved, so that the fixed frame 22, the counterweight block and the induction coil 20 can accumulate energy before moving, and the magnetic repulsion force can continue to load the counterweight block and the induction coil 20 during the movement, so that when the fixed frame 22 hits the brake plate 28, the push rod 16 and the impact head 17 can have enough kinetic energy to hit the screw of the high lock bolt The rod is used to make the screw rod fall off from the screw hole. The induction coil 20 and the loading coil 21 are controlled by the second switch 15 to generate opposite magnetic poles. The induction coil 20, the counterweight and the fixing frame 22 can be reset by magnetic attraction. At the same time, the magnetic attraction generated can also attract the magnetic block 26 to reset the push rod 16 and the impact head 17. In addition, when the polygonal column on the impact head 17 is inserted into the polygonal hole on the high locking bolt, the push rod 16 and the impact head 17 can also be reset. When resetting, the steering gear first moves the rocker arm. 47 makes the square frame 48 and the sliding sleeve 49 move. After the sliding sleeve 49 moves, the pull rod 51 and the locking tongue 52 are pushed to reset through the second spring 50. When the fixing frame 22 is reset, the cylinder 45 is inserted into the circular hole provided on the fixing frame 22. At this time, the inclined surface on the locking tongue 52 squeezes the chamfer on the cylinder 45. At this time, the second spring 50 contracts, so that the locking tongue 52 can move backward so that the cylinder 45 can be smoothly inserted into the circular hole. After insertion, the second spring 50 can push the locking tongue 52 out of the rectangular hole connected to the cylinder 45.

[0061] The operation steps of the technical solution are: when in use, the impact head 17 is first installed on the push rod 16, the sleeve 38 is inserted into the sleeve 6 and fixed to one end of the cross tube 31 with bolts, and the inner diameter of the sleeve 38 can be configured into a variety of sizes according to actual needs to adapt to the nuts of high locking bolts with different diameters;

[0062] After selecting the correct sleeve 38, insert the polygonal column on the impact head 17 into the polygonal hole at one end of the high locking bolt. When the polygonal column is inserted into the polygonal hole, it can limit the rotation of the screw when removing the nut, avoiding the rotation and failure to remove the nut;

[0063] After the driving assembly is started, the electromagnetic coil 32 generates a magnetic attraction force to attract the strong magnetic ring 30. The strong magnetic ring 30 moves to make the cross tube 31 push the sleeve 38 to move. The sleeve 38 hits the nut of the high-locking bolt. At this time, the triangular block 40 in the sleeve 38 uses its edge to cut a pit on the nut. After the pit is cut, the friction between the sleeve 38 and the nut is increased to avoid the nut being unable to be screwed when the torque increases. At the same time, the nut can be vibrated when hitting to make it easier to loosen;

[0064] Start the disassembly mechanism, use the reduction mechanism to drive the sleeve 6 to make the sleeve 38 generate a torsional force, use the low-speed and high-torque sleeve 6 and sleeve 38 to disassemble the nut of the high-locking bolt. After the disassembly is completed, remove the impact head 17 from the high-locking bolt, manually operate the driving component to reset, use the electromagnetic coil 32 to generate the same magnetic pole as one side of the strong magnetic ring 30, and use the magnetic repulsion to make the cross tube 31 push the sleeve 38 to reset. During the reset, the thrust ring on the impact head 17 blocks the nut of the high-locking bolt and makes it fall off from the sleeve 38 until the nuts to be disassembled are all removed. After removal, the next high-locking bolt can be disassembled, and the limit assembly is used. Lock the cross tube 31 and the sleeve 38, and then insert the impact head 17 into the multi-faceted hole on the high-locking bolt. Then start the loading mechanism, and use the magnetic stress wave generated by the induction coil 20 and the loading coil 21 to make the impact head 17 hit the screw of the high-locking bolt, so that the screw falls off from the screw hole until all the screws to be disassembled are removed. During the disassembly process, the screw rod 55 is rotated by starting the motor 19. When the screw rod 55 rotates, it drives the internal thread block 56 to move the rectangular rod 11. When the rectangular rod 11 moves, it drives the arc rod 8 to contact the structural part, thereby providing auxiliary support for the stress wave driving tool and improving the stability when disassembling the high-locking bolt.
