Description

Technical Field

[0001] This utility model relates to the field of aviation screw insert tool technology, specifically an aviation screw insert adjustment tool. Background Technology

[0002] Aviation-grade screw thread adjustment tools are specialized tools used in aircraft maintenance for the disassembly, installation, and adjustment of screw thread inserts.

[0003] However, existing technologies still have many defects in some similar structures when used in practice. For example, the tightening and loosening of the nut is usually located in different positions of the aircraft structure, which may be due to space limitations or special installation angles. If the adjustment tool cannot adjust the distance to the nut, it will be impossible to operate the nut. At the same time, in the assembly process of aerospace components, the tightening and loosening nut is usually used to connect and adjust the relative position and gap between components. If the nut cannot be tightened or loosened easily, it will be difficult to assemble the components into the precise position, resulting in a decrease in assembly accuracy.

[0004] To address the aforementioned problems, the inventors have proposed an aviation-grade tensioning screw adjustment tool to solve these issues. Utility Model Content

Multiple clamping blocks distributed in a ring array can clamp the threaded sleeve from multiple directions, which can effectively tighten or loosen the threaded sleeve.

[0009] As a preferred technical solution of this application, the top surface of the base plate is threaded with a plurality of bolts arranged in a rectangular array.

[0010] Through the above technical solution, the bolt can fix the base plate on the workbench, ensuring stability during processing and avoiding the impact of tool shaking on the adjustment accuracy of the tightness of the threaded sleeve.

[0011] As a preferred technical solution of this application, two guide rods are fixedly connected between the inner walls of the two sides of the base plate, and the lower part of the slide plate is movably sleeved with the guide rods.

[0012] Through the above technical solution, the guide rod that is movably connected to the bottom of the skateboard and the slider that cooperates with the slide groove play the role of guiding and restricting the direction of movement of the skateboard.

[0013] As a preferred technical solution of this application, the lower part of the skateboard is symmetrically and fixedly connected with sliders, and the inner walls on both sides of the base plate are provided with grooves for use with the sliders.

[0014] With the above technical solution, the slider slides within the inner wall of the groove.

[0015] As a preferred technical solution of this application, the outer surface of the fixing rod is in contact with the inner wall of the arc groove.

[0016] With the above technical solution, the fixing rod slides within the inner wall of the arc groove.

[0017] As a preferred technical solution of this application, the outer surface of the rotating plate is provided with a plurality of inclined grooves, and the end of the extrusion rod is in contact with the inner wall of the inclined groove.

[0018] With the above technical solution, when the extrusion rod rotates, it will push the rotating plate along the inclined groove.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model allows the slide plate to move along the axial direction of the lead screw when the lead screw rotates. The guide rod that is movably sleeved at the lower part of the slide plate and the slider that cooperates with the slide groove play the role of guiding and restricting the movement direction of the slide plate, ensuring that the slide plate moves smoothly in a straight line, thereby achieving the purpose of adjusting the distance between the adjustment tool and the screw sleeve. 2. When the extrusion rod rotates, it pushes the rotating plate along the inclined groove. The rotating plate rotates on the support plate, and the pull rod connected to the bottom surface of the rotating plate moves accordingly, causing the clamping block to rotate around the rotation connection point between the clamping block and the inner wall of the base, thereby achieving the clamping action of the threaded sleeve. Multiple clamping blocks distributed in a ring array can clamp the threaded sleeve from multiple directions, thereby achieving the purpose of effectively tightening or loosening the threaded sleeve.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example: Figure 1-4 As shown, this utility model provides an aviation loosening and tightening screw adjustment tool, including a base plate 1, a plurality of bolts 4 arranged in a rectangular array are threaded on the top surface of the base plate 1, and an adjustment device 3 is provided inside the base plate 1; The adjusting device 3 includes a lead screw 31, with both ends of the lead screw 31 rotatably connected to the inner walls of both sides of the base plate 1. A knob 32 is movably inserted through one side of the base plate 1, with one end of the knob 32 fixedly connected to the lead screw 31. A slide plate 33 is threaded onto the outer surface of the lead screw 31. Two guide rods 34 are fixedly connected between the inner walls of both sides of the base plate 1. The lower part of the slide plate 33 is movably connected to the guide rods 34. A slider 35 is symmetrically fixedly connected to the lower part of the slide plate 33. Slide grooves 36 that cooperate with the slider 35 are opened on the inner walls of both sides of the base plate 1. A rotating shaft 37 is rotatably connected to the upper part of the slide plate 33. A clamping device 2 is fixedly connected to the end of the rotating shaft 37.

[0028] When the lead screw 31 rotates, the slide plate 33 moves along the axial direction of the lead screw 31. The guide rod 34, which is movably sleeved at the lower part of the slide plate 33, and the slider 35, which cooperates with the slide groove 36, play the role of guiding and restricting the movement direction of the slide plate 33, ensuring that the slide plate 33 moves smoothly in a straight line. The distance between the adjustment tool and the screw sleeve can be adjusted.

[0029] The clamping device 2 includes multiple bases 20 arranged in a ring array. The bottom surface of the base 20 is fixedly connected to the rotating shaft 37. A support plate 21 is fixedly connected to the inner wall of the base 20. A clamping block 22 is rotatably connected between the inner walls of the two sides of the base 20. A pressing rod 23 is threaded onto one side of the clamping block 22. A rotating plate 24 is rotatably connected to the middle of the top surface of the support plate 21. A pull rod 25 is fixedly connected to the bottom surface of the rotating plate 24. Multiple arc grooves 26 arranged in a ring array are opened on the top surface of the rotating plate 24. Multiple fixing rods 27 arranged in a ring array are fixedly connected to the top surface of the support plate 21. The outer surface of the fixing rod 27 is in contact with the inner wall of the arc groove 26. A placement plate 28 is fixedly connected to the top of the fixing rod 27. Multiple inclined grooves 29 are opened on the outer surface of the rotating plate 24. The end of the pressing rod 23 is in contact with the inner wall of the inclined groove 29.

[0030] When the pressing rod 23 rotates, it pushes the rotating plate 24 along the inclined groove 29. The rotating plate 24 rotates on the support plate 21, and the pull rod 25 connected to the bottom surface of the rotating plate 24 moves accordingly, causing the clamping block 22 to rotate around the rotating connection point between it and the inner wall of the base 20, thereby realizing the clamping action of the threaded sleeve. The multiple ring array of clamping blocks 22 can clamp the threaded sleeve from multiple directions, which can effectively tighten or loosen the threaded sleeve.

[0031] The working principle of the aviation-grade loosening and tightening screw sleeve adjustment tool according to the embodiment of this application is as follows: the bolt 4 can fix the base plate 1 on the worktable to ensure stability during processing and avoid the adjustment accuracy of the loosening and tightening screw sleeve due to tool shaking. When the knob 32 is rotated, since one end of the knob 32 is fixedly connected to the lead screw 31, it will drive the lead screw 31 to rotate. The slide plate 33, which is threaded on the outer surface of the lead screw 31, will move along the axial direction of the lead screw 31 when the lead screw 31 rotates. The guide rod 34, which is movably sleeved at the lower part of the slide plate 33, and the slider 35, which cooperates with the slide groove 36, play the role of guiding and restricting the movement direction of the slide plate 33, ensuring that the slide plate 33 moves smoothly in a straight line, thereby achieving the purpose of adjusting the distance between the adjustment tool and the screw sleeve. Rotating the pressing rod 23 causes it to be threadedly connected to the clamping block 22, and the end of the pressing rod 23 is in contact with the inclined groove 29 on the outer surface of the rotating plate 24. When the pressing rod 23 rotates, it pushes the rotating plate 24 along the inclined groove 29. The rotating plate 24 rotates on the support plate 21, and the pull rod 25 connected to the bottom surface of the rotating plate 24 moves accordingly, causing the clamping block 22 to rotate around its rotation connection point with the inner wall of the base 20, thereby achieving the clamping action of the threaded sleeve. The multiple ring-shaped array of clamping blocks 22 can clamp the threaded sleeve from multiple directions, thereby achieving the purpose of effectively tightening and loosening the threaded sleeve.

[0032] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
