The end socket of this device.
Background technology
Often use end socket in chemical industry and other industries at present, and need the axis part in end socket to weld
The part needing or part, are then assembled.These parts being welded on end socket axis part or part often require that welding
In the positive axle center of end socket, the requirement to axiality is very high；Otherwise, not only have influence on the welding quality of product, and serious
Final assembling will be had influence on.Weld a part, this part and end socket it is desirable on end socket axis direction taking certain product as a example
The axiality in axle center needs to control in the range of 0.25 it is desirable to very strict.As the requirement of this axiality cannot be ensured, in product
Multiple adjustment and shaping will be carried out in assembling process, have a strong impact on production efficiency, cause the very big of human and material resources
Waste；And due to being assembling after shaping, easily produce stress concentration, and during the final use of product, may
Influence whether the final mass of product, be seriously to lead to the generation of security incident.Therefore, end socket axle center orientation parts is same
Axle degree ensures that problem is always the problem that relevant industries put forth effort to pay close attention to.
Technology contents according to the current national standard gb/t 25198-2010 of China " pressure vessel end socket " require,
For the processing of end socket, its diameter allows there is certain tolerance, according to the difference of diameter, its tolerance permitted range from ±

Specific embodiment
Below embodiments of the invention are elaborated, the present embodiment is carried out under premised on technical solution of the present invention
Implement, give detailed embodiment and specific operating process, but protection scope of the present invention is not limited to following enforcements
Example.
As shown in figures 1-4, the end socket 1 of the present embodiment, including centralising device 2, is fixed on gripper shoe 3 and within end socket 1
Treat the co-axially fixed axle sleeve 4 with end socket 1, centralising device 2 includes three groups of detent mechanisms 21, positioning sleeve 22, sliding sleeve 23 and central canal
24；Every group of detent mechanism 21 includes the first connector 211, the second connector 212, the 3rd connector 213, connecting rod 214 and elongation
Claw 215；First connector 211 is fixed on central canal 24, and the second connector 212 is fixed on sliding sleeve 23, the 3rd connector
213 are fixed on connecting rod 214, and the first connector 211, the second connector 212, the 3rd connector 213 are located at triangle respectively
On three summits；One end of described elongation claw 215 is hinged on the first connector 211, and the other end is hanging；The one of connecting rod 214
End is hinged on the second connector 212, and the other end passes through the 3rd connector 213 and elongation claw 215 is hinged；Described positioning sleeve 22
It is connected to the bottom of sliding sleeve 23, central canal 24 is set in sliding sleeve 23, the folder of the circumference along central canal 24 for the adjacent positioned mechanism 21
Angle is identical, and the two ends of gripper shoe 3 are fixed in end socket 1, and axle sleeve 4 is set on positioning sleeve 22, the free end position of elongation claw 215
On the inner surface of end socket 1.
Elongation claw 215 and connecting rod 214 need the nominal diameter according to end socket 1 to carry out necessary calculating or emulation mould
Intend, the most rational length is set out.When the nominal diameter of end socket 1 changes, elongation claw 215 and connecting rod 214 all accordingly enter
The necessary adjustment of row.Elongation claw 215 and connecting rod 214 are flexibly connected；When elongation claw 215 or connecting rod 214 because damage or
End socket 1 nominal diameter change and need change when, can be changed after pulling down, it is further provided the adaptability of this device and
Flexibility function.
First connector 211, the second connector 212 are identical with the structure of the 3rd connector 213, and each connector all includes
Clip 200, bearing pin 201 and in order to spacing circlip 202, described clip 200 is u-shaped, and the opening of u-shaped clip 200 sets
There is through hole, bearing pin 201 is set on described clip 200, one end of bearing pin 201 is provided with order to spacing projection, and the other end connects
Circlip 202, it can be ensured that stable connection, is unlikely to come off, and so elongation claw 215 can rotate around bearing pin 201, but not
Can come off；Elongation claw 215 end open up through hole, the bearing pin 201 on the first connector 211 pass through clip 200 on through hole and
The through hole of elongation claw 215 end；Through hole is opened up, the bearing pin 201 on the 3rd connector 213 passes through clip on elongation claw 215
Through hole on through hole on 200 and elongation claw 215；One end of connecting rod 214 is fixed on the clip 200 of the 3rd connector 213,
Through hole is opened up on the other end, the bearing pin 201 on the second connector 212 passes through the logical of through hole on clip 200 and connecting rod 214 end
Hole, circlip 202 is the annular ring being provided with opening.
The detent mechanism 21 of the present embodiment, positioning sleeve 22, sliding sleeve 23 and central canal 24 are made up of rustless steel.Not only ensure that
Overall is attractive in appearance, prevents simultaneously and gets rusty, improves the service life of this device.
In other embodiment, detent mechanism 21, positioning sleeve 22, sliding sleeve 23 and central canal 24 outer all claddings chromium coating, also may be used
To play antirust effect.
Positioning sleeve 22 and sliding sleeve 23 is threaded connection it is ensured that the detachability of positioning sleeve 22；Dimensions when axle sleeve 4
It is only necessary to change positioning sleeve 22 during change, it is allowed to corresponding with axle sleeve 4；Such that it is able to improve this device adaptability and
Flexibility function.
During work, end socket 1 is placed on the workbench of central aperture, connecting positioning sleeve 22 and axle sleeve 4, then centralising device
2 entirety puts into end socket 1, and now end socket 1 is not with axle sleeve 4 on the same line；Central canal 24 applies a downward power,
Now, central canal 24 slide downward in sliding sleeve 23, drives elongation claw 215 to move simultaneously, makes elongation claw 215 to end socket 1
Inwall move, and drive axle sleeve 4 gradually close to the center of end socket 1；According to three-point fix principle, when three extend claw
215 when all contacting with end socket 1 inner surface and no longer moving, and the axle center of axle sleeve 4 and end socket 1 on the same line, axle sleeve 4 is welded
It is connected in gripper shoe 3, thus ensure that the axiality of end socket 1 0.05.
When the interior diameter of end socket 1 becomes hour due to due to tolerance it is only necessary to carry central canal 24 upwards it is ensured that elongation blocks
Pawl 215 is in close contact, with the inner surface of end socket 1, the axiality requirement that can ensure axle sleeve 4 and end socket 1；Interior diameter when end socket 1
It is only necessary to firmly be pressed downward central canal 24 it is ensured that extending the inner surface of claw 215 and end socket 1 when becoming big due to tolerance reason
Close contact can ensure that axle sleeve 4 and the axiality of end socket 1 require.
Thus, the situation that the present invention can be changed with tolerance using diameter, embody the principle of flexible design.The present invention
Can be widely applied to positioning and the welding of various types of end socket 1 axle center orientation parts.
