Description

Technical Field

[0001] The utility model relates to the field of tools for aircraft maintenance, in particular to a quick installation and disassembly device for an earring joint. Background Art

[0002] As Figure 1 and Figure 2 shown, limited by the shape of the earring joint itself, when installing the first locking nut 11 and the second locking nut 12 on the external thread of the earring joint 1, it is necessary to start screwing in from the right end of the external threaded rod part of the earring joint 1. The existing assembly method is to manually or use an open-end wrench to rotate the nut, and gradually screw it in one circle by one circle to the left end of the earring joint 1. It screws in 1.5 millimeters per circle. The first locking nut 11 and the second locking nut 12 need to repeat the operation twice, and usually it takes about 20 minutes, with low efficiency and high labor intensity for the operator. Similarly, the operating rod 2 also needs to be screwed into the internal thread of the earring joint 1, and it also needs to start screwing in from the right end of the internal threaded rod part of the earring joint 1. The existing assembly method is to manually or use an open-end wrench to rotate the third locking nut 21, and gradually screw it in one circle by one circle to the left end of the earring joint 1. It screws in 1.5 millimeters per circle, and then adjusts the screwing depth of the operating rod 2 according to the assembly situation. This assembly method usually takes about 10 minutes to assemble one operating rod 2. Therefore, there are also defects of low efficiency and high labor intensity for the operator.

[0030] The present utility model will be further described in detail below with reference to the accompanying drawings of the specification and specific embodiments.

[0031] Figures 3 to 5 An embodiment of the quick installation and disassembly device for the earring joint of the present utility model is shown. The quick installation and disassembly device for the earring joint in this embodiment includes a U-shaped mounting member 3. On both sides of the mounting member 3, there are fixing components 4 for fixing the sides of the earring joint 1. On the mounting member 3, there is a polygonal clamping portion 31, and the orientation of the clamping portion 31 is opposite to the opening direction of the mounting member 3 (specifically refer to Figure 4 , in this embodiment, the clamping portion 31 is arranged towards the left, and the opening of the mounting member 3 is arranged towards the right).

[0032] Specifically refer to Figure 5 , for the quick installation and disassembly device for the earring joint in this embodiment, during operation, the fixing components 4 on both sides of the mounting member 3 can be used to fix the two sides of the earring joint 1, thereby preventing the earring joint 1 from shifting when being driven to rotate. The clamping portion 31 is used for the clamping of a variable-speed electric drill chuck or other automated tools. Start the electric drill to drive the overall rotation of the clamping portion 31, the mounting member 3, the fixing components 4, the earring joint 1, etc. At this time, as long as the locking nuts (the first locking nut 11, the second locking nut 12, and the third locking nut 21) and the operating rod 2 are fixed (for example, clamped by a vise or a strong clamp), the screwing assembly or disassembly of the thread can be quickly completed (assembly and disassembly only need to change the rotation direction of the electric drill). Compared with the existing manual rotation assembly method, the structure is simple, the degree of automation is high, the work efficiency is improved, and the labor intensity of the operator is reduced.

[0033] Furthermore, in this embodiment, the fixing component 4 includes an elastic dowel pin 41. The elastic dowel pin 41 can press the steel ball at the head end against the side of the earring joint 1 by using the internal spring, which can effectively prevent the earring joint 1 from shifting when being driven to rotate, and the structure is simple and reliable.

[0034] Even further, in this embodiment, the fixing component 4 further includes an adjusting pad 42 provided on the mounting member 3. The adjusting pad 42 is provided with an adjusting hole 421, and the elastic dowel pin 41 is threadedly connected with the adjusting hole 421. This structure can conveniently adjust the position of the elastic dowel pin 41 along the axial direction to ensure that the elastic dowel pin 41 can press against the side of the earring joint 1.

[0035] Even further, in this embodiment, the installation position of the adjusting pad 42 can be adjusted along the opening direction of the mounting member 3. By changing the installation position of the adjusting pad 42, the position where the elastic dowel pin 41 presses against the side of the earring joint 1 can be adjusted, which is more convenient to use and has stronger adaptability.

[0036] Specifically refer to Figure 4, in this embodiment, waist-shaped holes 32 are provided on both sides of the mounting member 3. The adjusting pad 42 has a T-shaped structure and is inserted into the waist-shaped holes 32. The end with a larger diameter of the adjusting pad 42 is located inside the mounting member 3, and a fixing nut 43 is provided at the end with a smaller diameter. After loosening the fixing nut 43, the position of the adjusting pad 42 can be changed along the waist-shaped holes 32. After the adjusting pad 42 is in place, tighten the fixing nut 43, and with the T-shaped structure of the adjusting pad 42 itself, the adjusting pad 42 can be reliably fixed on the mounting member 3, with a reasonable and effective structure.

[0037] As a preferred embodiment, an adjusting washer 44 is further provided between the adjusting pad 42 and the mounting member 3. By replacing adjusting washers 44 of different specifications, the distance between the adjusting pad 42 and the earring joint 1 can be changed, so as to fit with earring joints 1 of different thicknesses, making it more convenient to use and having a wider adaptation range.

[0038] As a preferred embodiment, the adjusting pad 42 is made of a non-metallic material, such as rubber or plastic, etc. The non-metallic material helps to avoid bumping with the earring joint 1 and causing damage to the earring joint 1.

[0039] Furthermore, in this embodiment, a positioning pin 33 is also provided on the mounting member 3. The orientation of the positioning pin 33 is the same as the opening direction of the mounting member 3, and a tapered tip 331 is provided at the end of the positioning pin 33. The tapered tip 331 can cooperate with the central hole 13 on the earring joint 1 to play a role in rotational centering, further improving the reliability of the device.

[0040] As a preferred embodiment, both the positioning pin 33 and the clamping portion 31 are provided in the middle of the mounting member 3. Correspondingly, the two sets of fixing components 4 are symmetrically arranged on both sides of the positioning pin 33 and the clamping portion 31, with good symmetry and balance, which is beneficial to ensuring stability during the rotation process.

[0041] As a preferred embodiment, the clamping portion 31 has a regular hexagon structure, which is convenient for clamping the drill chuck of a variable-speed electric drill. Of course, in other embodiments, the clamping portion 31 can also be a triangular structure, a square structure, etc., which will not be elaborated here.

[0042] Although the present utility model has been disclosed above with preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make many possible changes and modifications to the technical solution of the present utility model, or modify it into an equivalent embodiment with equivalent changes, without departing from the scope of the technical solution of the present utility model. Therefore, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model without departing from the content of the technical solution of the present utility model shall fall within the scope of protection of the technical solution of the present utility model.
