Abstract
The utility model discloses a vaulting pole is used in assembly of small -size sealing ring in dark elongated hole, the vaulting pole is circular cone and cylinder along the axial in proper order, and the axial of following the vaulting pole is provided with the guiding groove that spanes round conic section and cylindrical section in 180 symmetries at the side interval of vaulting pole, and the guiding groove becomes shallow until the disappearance from the branch boundary point of circle conic section and cylindrical section toward its degree of depth of cylindrical section rear end gradually, the utility model discloses the guiding groove of gradual change is set up in 180 symmetries at the side interval of vaulting pole for the vaulting pole stretches into the in -process of sealing ring, and the fold of sealing ring progressively expandes along the gradual change of guiding groove, and consequently, the fine has avoided the sealing ring to receive temporal overstocking and taken place the condition that the fold is unable and the seal groove is laminated completely, and the success rate of assembly has obtained very big improvement.
Description
Technical field
This utility model belongs to machining and mounting technology field, small size sealing ring dress in particularly a kind of deep elongated hole
Adapted strut.
Background technology
In the mechanical assembly field that some is special, need to install undersized sealing ring in deep elongated hole, owing to machinery is
One-body molded mechanism, it is necessary to install sealing ring inside from only opening part, it is therefore desirable to special assembly technology could be real
The installation of existing sealing ring.
Existing frequently-used sealing ring assembly method is first to be pinched by sealing ring with tweezers so that it is profile is compressed, and should
Sealing ring tweezers are sent in the seal groove in deep elongated hole；Because sealing ring self has certain elastic deformation, when unclamping tweezer
After son, do not fall off in sealing ring can stick into seal groove automatically；Then stretch with the stock of a front end taper back end cylindrical shape
Entering in deep elongated hole, sealing ring can be strutted by stock so that it is fits with seal groove；But but there will be close in actually used
The problem that seal ring cannot extend smoothly.It has been investigated that, when stretching in deep elongated hole due to stock, due to sealing ring
Overstock by moment, therefore, it is very easy to occur that sealing ring does not extend according to anticipation after being squeezed, but fold
Place is overstock, and causes sealing ring not fitted with seal groove, thus causes sealing property the best.
Utility model content
The purpose of this utility model is to provide one to enable to sealing ring and slowly extend, it is to avoid sealing ring is subject to
Moment overstocks and cannot complete small size sealing ring assembling strut in the deep elongated hole of predetermined stretching, extension.
The technical solution realizing this utility model purpose is:
Small size sealing ring assembling strut in a kind of deep elongated hole, strut is followed successively by circular cone and cylinder vertically, along strut
Axial the side of strut be spaced 180 ° of guiding grooves being symmetrically arranged with across conical section and cylindrical section, guiding groove is from circle
The separation of cone section and cylindrical section gradually becomes shallower as until disappearing toward its degree of depth of cylindrical section rear end.
This utility model compared with prior art, its remarkable advantage:
This utility model is spaced 180 ° of guiding grooves being symmetrical arranged gradual change in the side of strut so that strut stretches into sealing ring
During, the fold of sealing ring is progressively to launch along the gradual change of guiding groove, therefore, well avoids sealing ring
Situation about being overstock by moment and occur fold cannot fit completely with seal groove, the success rate of assembling has obtained greatly
Improve.
Below in conjunction with the accompanying drawings this utility model is described in further detail.
Accompanying drawing explanation

Detailed description of the invention
In conjunction with Fig. 1:
Small size sealing ring assembling strut in a kind of deep elongated hole of this utility model, strut is followed successively by circular cone and circle vertically
Post, along strut axial the side of strut be spaced 180 ° of guiding grooves being symmetrically arranged with across conical section and cylindrical section,
Guiding groove gradually becomes shallower as until disappearing toward its degree of depth of cylindrical section rear end from the separation of conical section and cylindrical section.
The cylindrical section rear end of strut arranges Anti-slip handle.
Guiding groove is the dovetail groove of bottom belt circular arc.
Two waist angles of dovetail groove are 25 °～40 °；Guiding groove axis is 3 °～6 ° with the angle of strut axis.
In conjunction with Fig. 2～Fig. 3:
Operation principle of the present utility model:
First with tweezers, sealing ring is become 8-shaped according to the shape kneading shown in Fig. 2, and these sealing ring tweezers are sent into
In seal groove in deep elongated hole.Because sealing ring self has certain elastic deformation, after unclamping tweezers, sealing ring can be certainly
Move and do not fall off in sticking into seal groove.Then, shown in Fig. 3, putting in hole by the strut of band guiding groove, noting will
Two deformation projections that two guiding grooves on strut are respectively aligned on sealing ring.Along the strut direction of motion shown in Fig. 3
Strut is injected in deep elongated hole, until it reaches the position shown in Fig. 4.Finally extract strut, check that sealing ring is the completeest
It is extended into well "○" shape.
