Description
Technical field
The utility model relates to the hand-operated tools in metal plate assembly, specifically a kind of Closely locking nut removers.
Background technique
In aviation, the component of high locked bolts and Closely locking nut assembly, upon installation, Closely locking nut are used
Retained part is twisted into two parts（As shown in Figure 4, Figure 5）, because not having retained part to make when needing to remove Closely locking nut in maintenance and repair
Difficult at removing, working efficiency is low.Therefore it is sought after a kind of tool for removing Closely locking nut, to adapt to the needs of maintenance work.
Summary of the invention
To overcome the difficulty in Closely locking nut dismounting, reduces the labor intensity of operator, improves production efficiency, this is practical new
Type provides a kind of Closely locking nut remover, to meet the demand in maintenance work.
The technical solution of the utility model is as follows, and Closely locking nut remover includes allen wrench, and composition further includes cone
Shape elastic collet, conical ring, locking nut, bushing, cone-shaped flexible folder head portion are provided with the rectangular channel being not penetrated along axial direction,
For taper ring set on cone shaped elastic collet, cone shaped elastic collet lower part is equipped with locking nut and bushing, locking nut and Conical Projectile
Property collet be threadedly coupled, allen wrench is inserted into from bushing, constitutes complete remover.
Cone-shaped flexible folder head portion is covered on the Closely locking nut to be removed when work, makes remover collet end and assembly
Component is close to, and rotates counterclockwise locking nut, while carrying on the back elastic collet with spanner, rotates it not together, at this time elastic clip
Head retaining part is by radial compression power, and the face A and the axial distance in the face B on conical ring on elastic collet become smaller, conical ring
Elastic collet is squeezed, the aperture for making elastic collet clamp position becomes smaller, and clamps Closely locking nut, and allen wrench is inserted into high lock spiral shell
It in the interior hexagonal hole of bolt, prevents high locked bolts from rotating together with Closely locking nut, continues to rotate counterclockwise locking nut, until high lock
Nut is removed, and then rotates clockwise locking nut, unclamps elastic collet, takes out the Closely locking nut removed, and process is completed.
The beneficial effects of the utility model are as follows：1, structure is simple, easy to use and operate, selects the dismounting of different size
Device can efficiently complete the dismounting of various specifications Closely locking nut, be used cooperatively better effect with ratchet spanner；2, due to cone shaped elastic
Collet marmon clamp compact form, demolishing process Closely locking nut uniform force, is unlikely to deform, therefore will not damage the spiral shell of high locked bolts
Line, high locked bolts are recyclable to be reused, save the cost；3, small in size, it can be used in small space.

Specific embodiment
Illustrate specific embodiment of the present utility model with reference to the accompanying drawing, as shown in Figure 1, Closely locking nut remover includes
Allen wrench 8, composition further includes cone shaped elastic collet 4, conical ring 5, locking nut 6 and bushing 7, cone shaped elastic collet 4
Head is provided with 4 rectangular channels being not penetrated, varying aperture when realizing work along axial direction, and inner cavity retaining part is formed with anti-slop serrations
（As shown in Figure 3）, 5 sets of conical ring on cone shaped elastic collet 4,4 lower part of cone shaped elastic collet be equipped with locking nut 6 and bushing 7,
Locking nut 6 and cone shaped elastic collet 4 are threadedly coupled, and allen wrench 8 is inserted into from bushing 7.As shown in Figure 1, on assembly parts 1
Equipped with high locked bolts 2 and Closely locking nut 3, the inner hole sleeve of cone shaped elastic collet 4 is interior on the Closely locking nut 3 to be removed when work
In the interior hexagonal hole of the high lock snail 2 of hexagon insertion, dismounting work can be carried out by foregoing routine.
The cone shaped elastic collet 4 of the utility model makes of 65Mn spring steel, thermally treated and surface treatment, other parts
It is made of No. 45 steel, conditioned and surface oxidation treatment.
