Hole flange, equal part has eight bolts on porous flange, and eight are bolted the big copper draw runner of eight copper draw runners i.e. four and four small
Copper draw runner, four big copper draw runner respectively correspond installation there are four big fanning strip, and four small copper draw runner respectively corresponds there are four installations
Small fanning strip.
As an improvement of the present invention, gradient relation is 1:4 between the big fanning strip and big copper draw runner, small fanning strip
Gradient relation is 1:2.8 between small copper draw runner.When i.e. oil cylinder drives copper draw runner transverse shifting 4mm, four pieces big fanning strip respectively rises
It opens or reduces 1mm, when oil cylinder drives copper draw runner transverse shifting 2.8mm, each spreading of four pieces small fanning strip or reduce 1mm, oil cylinder is living
The thread of stopper rod is M75 × P2.
Mandrel for recoiling machine outer circle method of adjustment, which is characterized in that the method is as follows:
The first step first measures reel axle diameter with vernier diameter ruler (PAI ruler) in compressor emergency shutdown, records data；
Second step, if identical as normal diameter Φ 413.2mm with vernier diameter ruler (PAI ruler) air plug gauge diameter, four
Block fritter fanning strip recess is gone down, then oil cylinder stroke just has been adjusted to position, respectively on four small fanning strips according to
Sequence mark a, b, c, d, make coiler mandrel be in spreading state, measure the amount of deflection with outside micrometer and Steel Ruler,
Mobile distance is needed according to the zero-bit that data can calculate four pieces small copper draw runner；
Third step increases gasket on copper draw runner,
4th step, it is ensured that the filling-up area of fanning strip is abundant to grease, it is ensured that between pull rod, mandrel, copper draw runner and fanning strip
There is enough lubricating grease, reel mandrel harmomegathus experimental test is repeated, measures drum diameter.Outside by a kind of mandrel for recoiling machine
Mandrel for recoiling machine diameter, can be corrected to proper circle shape by the application of circle method of adjustment, thoroughly eliminate heart-shaped volume defect.
As an improvement of the present invention, the first step is specific as follows: the first situation: if axle diameter and standard
Diameter of phi 413.2mm difference is larger, can first adjust the diameter of a circle that oil cylinder stroke forms four pieces big fanning strip by conversion
It is corrected to Φ 413.2mm.Assuming that a circular diameter Φ and standard Φ 413.2mm of four pieces big fanning strip spreading composition is poor on mandrel
Value is △ x, then needing to adjust oil cylinder stroke are as follows:
L=(△ x/2) × 4=2 △ x mm is 1.
At this point, the circular diameter Φ ' and standard Φ 413.2mm difference of four pieces of reel small fanning strip spreading composition are △
X ', after can calculating adjustment oil cylinder stroke, difference in diameter becomes:
△ x '=Φ '-Φ 413.2+ △ Φ ' is 2.
Wherein, Φ ' is a diameter of a circle of the four pieces small fanning strip spreading composition measured with vernier diameter ruler.
△ Φ '=(L/2.8) × 2=(2 △ x/2.8) × 2=10 △ x/7
If △ x '≤0.3mm (this value is the empirical value for manufacturing and using actual achievement accumulation), it is living to need to adjust oil cylinder
The angle of the rotation of stopper rod are as follows:
W=L/2 × 360 °=△ x*360 ° is 3.
I.e. under the conditions of rotary oil cylinder release, the fixed simultaneously cap of piston rod is unclamped, by piston rod rotation W angle.If △ x
For positive value, cylinder piston rod is adjusted rotationally clockwise；If △ x is negative value, adjustment cylinder piston rod counterclockwise turns
It is dynamic.
If △ x ' > 0.3mm, value cannot be had adjusted on the basis of △ x.This is because four pieces of small fanning strips
Spreading diameter is more too many greatly than four pieces big fanning strip spreading diameter, can deform big fanning strip edge top after small fanning strip spreading, lead
The fact that cause damages, general is fewer, can generate when mainly mandrel assembles serious wear or the low accuracy of manufacture；
After there is such case, reel can be adjusted according to the methods below:
It is worth on the basis of △ x ', adjusts the stroke of oil cylinder are as follows:
L '=(x '/2 △) × 2.8=1.4 △ x ' mm
So need to adjust the angle of the rotation of cylinder piston rod are as follows:
* 360 ° of the △ x ' of W '=(L '/2) × 360 °=0.7
If △ x ' is positive value, adjustment cylinder piston rod is rotationally clockwise；If △ x ' is negative value, adjustment oil cylinder is living
Stopper rod rotates in an anti-clockwise direction；
Since gradient relation is 1:4 between big fanning strip and copper draw runner, gradient relation between small fanning strip and small copper draw runner
It is 1:2.8, after oil cylinder transverse shifting L ' stroke, the spreading diameter of four pieces big fanning strip is straight less than the spreading of four pieces of small fanning strips
Diameter, so there is no interfere problem, that is, △ x ' < 0.3mm；
Next, big fan-shaped board diameter is adjusted again, at this point, a circular diameter Φ of four pieces of reel big fanning strip spreading composition
It is △ x with standard Φ 413.2mm difference, after can calculating adjustment oil cylinder stroke, difference in diameter becomes:
△ x=Φ-Φ 413.2+ △ Φ
Wherein Φ is a diameter of a circle of the four pieces big fanning strip spreading composition measured with vernier diameter ruler.
△ Φ=(L '/4) × 2=(1.4 x '/4 △) × 2=0.7 △ x '.
As an improvement of the present invention, the second step is specific as follows: assuming that diameter between small fanning strip a and c with
Standard Φ 413.2mm differs △ y ', and the medium and small concave height of fanning strip a is △ y1 ', then the small copper of corresponding small fanning strip a
The small copper draw runner of draw runner and corresponding small fanning strip c need to be respectively as follows: at a distance from movement
L1 '=2.8 × △ y1 ' is 4.
L3 '=2.8 × (△ y '-△ y1 ') is 5.
The corresponding small copper draw runner of small fanning strip b and d needs mobile distance L2 ', L4 ' calculation method as above identical.As
A modification of the present invention, the third step are specific as follows:
31), retract rotary oil cylinder piston bar, reel mandrel is in deflated state；When rotary oil cylinder piston bar retracts
When, drive 8 pieces of copper draw runners to move laterally together, due to there is trapezoidal mating surface between copper draw runner and fanning strip, fanning strip can be with
The change at trapezoidal angle and radial motion, amount of exercise relationship proportional to cylinder piston rod amount of movement.The principle of shimming is exactly to change
Become the zero point cooperation position of trapezoidal mating surface, thus change the final position of fanning strip, the thickness i.e. L1 ' of gasket, L2 ',
The numerical value of L3 ', L4 '；
32), remove reel mandrel by army cap；
33) label: A, B, C, D, a, b, c, d, is performed in porous flange screw hole site respectively, is compiled with corresponding fanning strip
It is number consistent, remove porous flange；
The gasket of correspondingly-sized is put on corresponding bolt, needs to be glued together between gasket, it is very easy when not so installing
It falls.
34) it, returns and fills porous flange, return dress for army cap.
Compared with the existing technology, the invention has the advantages that, the technical solution is by with vernier diameter ruler air plug gauge
