Problems solved by technology

[0003] 1. The seat ring connected with a joint bolt is installed on the fitting rib by extrusion. Once the verticality of the hole is not good, the inner wall of the seat ring is damaged by more than 0.3mm during hole making, and the expansion force of the seat ring hole will be reduced. Not enough, the rotation of the bolts during assembly will cause the seat ring to fall off, resulting in a lot of rework
[0004] 2. If the verticality of the hole is not good, there will be a gap between the bolt head and a joint surface, which will affect the connection strength and reliability of the aircraft

Embodiment 1

[0038] The utility model is realized through the following technical solutions, as figure 1 As shown, a positioning device to ensure the verticality of the hole in a special area is used in conjunction with the reamer 4 to ream the primary hole that has been made, including a guide bolt 1 with a guide hole 11, which cooperates with the guide bolt 1 Using the nut 2 provided with the clamping convex portion 21 and the seat ring 3 used in conjunction with the clamping convex portion 21 and provided with the connecting portion 31, the guide bolt 1, the nut 2, and the seat ring 3 are sequentially connected to form a whole. The guide hole 11 is arranged along the axial direction of the guide bolt 1 .

[0039] It should be noted that, through the above improvements, the first choice is to press the end of the seat ring 3 without the connecting part 31 into the beam (at the joint), and the guide bolt 1, the nut 2, and the seat ring 3 are connected in sequence to form a whole, and then...

Embodiment 2

[0042] This embodiment is further optimized on the basis of the above embodiments, such as figure 1 As shown, further, in order to better realize the present invention, the seat ring 3 includes a stepped shaft and a through hole 313 coaxial with the stepped shaft, the larger end of the stepped shaft is a connecting portion 31 and is connected to the nut 2, The diameter of the through hole 313 is larger than the outer diameter of the guide bolt 1 .

[0043] Other parts of this embodiment are the same as those of the foregoing embodiments, so details are not repeated here.

Embodiment 3

[0045] This embodiment is further optimized on the basis of the above embodiments, such as figure 1 As shown, further, in order to better realize the present invention, the connecting part 31 is arranged on the side of the seat ring 3 close to the nut 2, including a nut installation groove 312, a spring 3111 for fixing the nut 2 and the seat ring 3 together, and A spring installation slot 311 is provided along the side of the connecting portion 31 and is used for installing a spring 3111 . The spring installation groove 311 is connected with the nut installation groove 312 , and the size of the nut installation groove 312 matches the clamping protrusion 21 .

[0046] It should be noted that, through the above improvements, the clamping convex portion 21 of the nut 2 is installed in the nut installation groove 312, and the clamping convex portion 21 on the side away from the seat ring 3 is realized by the spring 3111 installed in the spring installation groove 311. Buckle and ...

Abstract

The invention discloses a positioning device for ensuring the perpendicularity of a made hole in a special area and a using method thereof. The positioning device cooperates with a reamer for being used for reaming a made primary hole and comprises a guide bolt provided with a guide hole, a nut cooperating with the guide bolt for use and provided with a clamping boss, and a seat ring cooperating with the clamping boss for use and provided with a connecting part, wherein the guide bolt, the nut and the seat ring are sequentially connected to form a whole body; and the guide hole is formed in the axial direction of the guide bolt. A special reamer is adopted for passing through a through hole from the end, far away from the guide bolt, of the seat ring for reaming the primary hole. Comparedwith the prior art, the positioning device has the advantages that the guide bolt is fixed on the seat ring and the perpendicularity of the hole is corrected by taking the guide bolt as a guide; the use is fast and convenient, safety and reliability are realized, holes made by workers of any skill levels can meet the requirements of technical conditions; and the cost is effectively reduced, and the manufacturing is low.

Description

technical field [0001] The invention relates to the technical field of aircraft assembly positioning, in particular to a positioning device for ensuring the verticality of a hole in a special area and a method for using the same. Background technique [0002] When making a hole at a joint of a certain type of machine, due to special connectors and special structural restrictions (mainly the angle between the rib strip surface of the mounting seat ring and the double plate surface is about 10 degrees), it is difficult to ensure the accuracy of the hole making Perpendicularity, if the verticality of the hole does not meet the relevant technical requirements, it will lead to the following quality hazards: [0003] 1. The seat ring connected with a joint bolt is installed on the fitting rib by extrusion. Once the verticality of the hole is not good, the inner wall of the seat ring is damaged by more than 0.3 mm during hole making, and the expansion force of the seat ring hole wi...
