Embodiment
Below in conjunction with the drawings and specific embodiments to the centre of form position provided by the utility model suitable for different pipe calibers
Concentrator marker is put to be described in further detail.With reference to following explanation and claims, advantages and features of the present utility model will more
It is clear.It should be noted that accompanying drawing uses using very simplified form and non-accurately ratio, only to convenient, apparent
Ground aids in illustrating the purpose of the utility model embodiment.
Refer to Fig. 1 and Fig. 2, the position of form center concentrator marker 100 suitable for different pipe calibers in the present embodiment, including
Outer force circle 110, interior force circle 120, center of circle mark 130,3 support arms 140 of light target and 3 force connecting rods 150.
Wherein, outer force circle 110 is circular ring structure；Interior force circle 120 is embedded in outer force circle 110, is enclosed with outer force
110 is concentric, and interior force circle 120 can enclose 110 relative to outer force around the axle center and rotate.
Wherein, center of circle mark light target 130, it is fixed on interior force circle 120, the center of circle is identified with the mark light target 130 of the center of circle,
The axle center of interior force circle 120 passes through the center of circle.
Wherein, 3 one end of support arm 140 are angularly articulated with outer force circle 110, and the other end is free end, can be around hinge
Contact is positioned at 110 place rotation with surface of outer force circle.The pin joint of 3 support arms 140, positioned at force circle 110 in addition
Axle center for the center of circle circumference on.
Wherein, one end of 3 force connecting rods 150 is angularly hinged on interior force circle 120, the other end and support arm 140
It is be hinged.3 force connecting rods 150 enclose 120 pin joint with interior force, and the axle center of force circle 120 is the circumference in the center of circle within being located at
On；The pin joint of 3 force connecting rods 150 and support arm 140, positioned at the axle center of force circle 110 in addition on the circumference in the center of circle.
The position of form center concentrator marker 100 suitable for different pipe calibers that the present embodiment provides, using " donut drives
It is dynamic " pattern, i.e., relatively rotated between interior force circle 120 and outer force circle 110, as pin joint A, (support arm 140 and outer force are enclosed
110 pin joint) and pin joint B (force connecting rod 150 and it is interior force circle 120 between pin joint) close to when, exert a force connecting rod 150
Drive the free end synchronous expansion of 3 support arms 140；When pin joint A is away from pin joint B, force connecting rod 150 drives 3 branch
The free end of brace 140 is synchronous to be closed to the center of circle.
Meanwhile the present embodiment positions to the center of circle and uses " three-point fox method ", that is, base is used as by 3 points using on circumference
Standard, a center of circle can be uniquely determined.The center of circle O that the center of circle mark light target 130 of position of form center concentrator marker 100 identifies, 3 support arms
140 free end is located at using center of circle O as the center of circle, using R as on the circumference of radius, during support arm 140 deploys and closed,
Radius R's gradually changes, and position of form center concentrator marker 100 is adapted to the pipe of different tube diameters.When the freedom of 3 support arms 140
End is when being supported on round tube inner wall, and the center of circle O that center of circle mark light target 130 identifies is the pipe cross section center of circle, i.e., so-called tubular
The heart.
Position of form center concentrator marker 100 in this implementation has the following advantages that：(1) 3 support arm 140 can be synchronized with the movement,
The circular radius R of 3 free end of support arm 140 compositions of regulation, can make position of form center concentrator marker 100 adapt to different inner diameters
Pipe, there is preferable versatility；(2) position of form center concentrator marker 100 is formed by the free end of support arm 140 with round tube inner wall
3 contact points, the pipe centre of form is determined by 3 point locations, the centre of form position that thereby determines that relatively low to pipe end requirement on machining accuracy
It is higher to put precision.

On, the other end is fixed on interior force circle 120.Under the pulling force of spring, the free end of support arm 140 is in expansion trend.As
Citing, one end of spring are fixed on pin joint A, and the other end is fixed on the pulling force of pin joint B, pin joint A and pin joint B in spring
Effect is lower to be relatively rotated, and pin joint B is strutted support arm 140 close to pin joint A, force connecting rod 150, make support arm 140 from
It is supported in by end on the inwall of pipe.
Free end in order to facilitate support arm 140 is kept closed after construction, is preferably, position of form center mark
The retention mechanism relatively rotated between restricted interior force circle 120 and outer force circle 110 is set on device 100.Under external force,
Acting force of the spring can be offset, the free end of support arm 140 is closed, is then fixed by retention mechanism.As an example, fasten
Mechanism includes being arranged on the through hole 2 141 that outer force is enclosed on through hole 1 and support arm 140 on 110, and is securable to lead to
Snib 112 in hole 1 and through hole 2 141, it when external force offsets spring force, can close the free end of support arm 140,
Now through hole 1 and through hole 2 141 are in overlap condition, and insertion snib 112 can make support arm oneself when cancelling external force
By holding still in closure state.
Preferred embodiment is that support rubber tire 142 is provided with the free end of support arm 140, and support rubber tire 142 is advantageous to
The free end of support arm 140 is supported on round tube inner wall, while also ensures that point is formed between support arm 140 and pipe to be contacted.
Larger frictional force is produced during relative motion between interior force circle 120 and outer force circle 110 in order to reduce, is applied inside
Rolling mechanism is provided between power circle 120 and outer force circle 110, the rolling mechanism can be the rolling being arranged on the two contact surface
Pearl, roller bearing, roller.For example force encloses 120 with setting some rollers, interior force circle on outer 110 corresponding sides of force circle inside
120 are contacted by roller with the inwall point of outer force circle 110, can be with frictional force during the two less relative motion.
Preferably, limited position mechanism is set between force circle 110 and interior force circle 120 outside, phase therebetween can be limited
To the angle of rotation, as an example, the limited post and be arranged at interior force circle that position-limit mechanism can be provided on outer force circle
On stopper slot, inside force circle 120 with it is outer force enclose 110 relatively rotate when, limited post rotates in stopper slot.Should be according to branch
The position of limited post determines stopper slot end positions when brace 140 is fully deployed and closed completely.
Preferably, mark light target 130 in the center of circle is lucite, is provided with tracking cross above, the intersection point of tracking cross is
The center of circle of interior force circle 120 and outer force circle 110, while be also the center of circle of circumference where the free end of support arm 140.
