124.
As a kind of embodiment, elastic component 132 is spring.
In the present embodiment, the first groove is set in the end of body 110, one end of elastic component 132 is fixed on first recessed
In groove, one end of connecting rod 134 arranges the second groove, and the other end of elastic component 132 is fixed in the second groove.
As a kind of embodiment, guide bar 100 also includes sheath 140.Sheath 140 is tubulose, is sleeved on elasticity even
On connected components 130.
As a kind of embodiment, one end of sheath 140 is connected on body 110.
In the present embodiment, sheath 140, using the straight tube with certain rigidity, not only can protect elastic connecting component 130,
The axial location of elastic connecting component 130 can also be limited.Sheath 140 can also adopt the corrugated tube of plastics.
As a kind of embodiment, as shown in Fig. 2 the small end 122 of target seeker 120 is taper, the tip of taper is remote
Larger end 124 from target seeker 120.During work, the tip of the taper of target seeker 120 is in motion foremost, reaches at first
To the end of copper pipe, most advanced and sophisticated design can preferably probe into copper pipe, and during gradually probeing into, taper can be by copper pipe
Axial location slowly adjusts along the gradient, finally by its position adjustment to the center overlapping of axles with target seeker 120, arrival in copper pipe
The purpose of guiding.
As a kind of embodiment, the larger end 124 of target seeker 120 and the junction of the small end 122 of target seeker 120
Using spherical arc 126.The centre of sphere of spherical arc 126 is located on the central shaft of target seeker 120 that is to say, that spherical arc 126
Towards target seeker 120.In guided procedure, target seeker 120 probes into copper pipe, until the end of copper pipe is contacted with spherical arc 126.
As a kind of embodiment, please in conjunction with shown in Fig. 1, female thread is set at the larger end 124 of target seeker 120,
In connecting rod 134, external screw thread is set away from one end of elastic component 132；Target seeker 120 is threaded connection with connecting rod 134.
As a kind of embodiment, the quantity of target seeker 120 is multiple, and the small end 122 of each target seeker 120 has
Different size.
Threaded mode can easily and quickly be dismantled or change target seeker 120, by all target seekers 120 and even
Screw thread design on extension bar 134 is unified specification, makes the scope of application of guide bar 100 very wide.And threaded do not need it
His connection assist, easy to use, reliability is high.
As a kind of embodiment, as shown in figure 1, setting elastic connecting component 130 in free state, on body 110
Installing the distance between the position of sheath 140 and the larger end 124 of target seeker 120 is l1, and the length of sheath 140 is l2, l2 ＜
l1.After the spherical arc 126 of target seeker 120 is contacted with copper pipe, elastic connecting component 130 at most can shorten l1-l2 inward.Pass through
The control of l1-l2 numerical values recited can limit the stroke in axially-movable for the target seeker 120.
Refer to shown in Fig. 3, it is the guiding device schematic front view in working order of the present invention, a kind of guiding dress
Put, including above-mentioned guide bar 100 and guiding actuator.
The quantity of guide bar 100 is multiple, and guiding actuator Driving guide bar 100 passes through fin hole, and target seeker 120 is relatively
Small end 122 reaches copper pipe End, and guiding actuator continues Driving guide bar 100 and moves, the globular arc of copper pipe and target seeker 120
Face 126 contacts, and guiding actuator continues Driving guide bar 100 and moves, and elastic connecting component 130 starts to compress, until target seeker
120 larger end 124 abuts to the end of sheath 140, and the length of elastic connecting component 130 can not shorten again.
When the two ends of u shape copper pipe have range difference l, the guide bar 100 of lower section reaches the corresponding copper pipe end in position
During portion, the guide bar 100 of top does not also reach the corresponding copper pipe End in position；Guiding actuator drives all of guide bar
100 are synchronized with the movement, and the spherical arc 126 of the target seeker 120 of lower section is contacted with copper pipe, and the elasticity in the guide bar 100 of lower section is even
Connected components 130 start to shorten；The guide bar 100 of top continues motion, reaches the corresponding copper pipe End in position；Top lead
Draw bar 100 and probe into the corresponding copper pipe in position, until the spherical arc 126 of the target seeker 120 of top is contacted with copper pipe.
Reach end-state, elastic connecting component 130 reduction length of the guide bar 100 of lower section is l, the guide bar of top
100 elastic connecting component 130 is in free state.By the spherical arc 126 of target seeker 120, the end of copper pipe is had
Effect positioning, and in fin poling technical process, make copper pipe persistently keep axial location constant.
In the same manner, when the position of multiple copper pipes has differences, the guide bar of guiding device can also be in certain scope
It is adjusted, the most all of copper pipe accurate positioning.Adjustment l1 and l2 is respectively worth, can be according to the actual requirements in different scopes
Inside be adjusted, guiding device use more flexible, scope is more extensive.
In the process, due to the elastic compression of elastic connecting component 130, the position making target seeker 120 can be in certain model
Enclose interior floating shifting, it is to avoid with copper pipe rigid contact, prevent guide bar 100 and copper pipe to be damaged, lead to the failure of fin poling technique,
Prevent hidden danger of quality.The guide bar of the present invention and guiding device improve the accuracy of guiding, poling work in technical process
The accuracy of skill,
Embodiment described above only have expressed the several embodiments of the present invention, and its description is more concrete and detailed, but simultaneously
Therefore the restriction to the scope of the claims of the present invention can not be interpreted as.It should be pointed out that for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, some deformation can also be made and improve, these broadly fall into the guarantor of the present invention
Shield scope.
