Embodiment
The utility model is described in further detail with reference to specific embodiment.
As shown in Figure 1 to Figure 3, the utility model is a kind of coaxial localization tool of flange pipeline, including with tapering and cylinder
The expander 24 in portion and the regulating bolt 21 penetrated from cylinder portion rear, are cased with sleeve 23 between expander 24 and regulating bolt 21,
Sleeve 23 is provided with the cavity 231 penetrated for cylinder portion and some square holes 233 around cavity 231 uniformly, expander 24 and sleeve 23
Between be clamped with the expanding block 25 of the corresponding quantity of square hole 233, each expanding block 25 has the conical surface with taper fit, expanding block
The adjustable shelf 26 of a perpendicular type is fixed with 25, the one side of adjustable shelf 26 is fixed with expanding block 25, and another side penetrates square hole 233 simultaneously
The base 22 of dish-type can be fixed with the one side close to regulating bolt 21 along the radial motion of sleeve 23, sleeve 23.The axle of tool
Axis, the axis of sleeve 23 and the axis collinear of base 22 of line and expander 24.Cavity 231 can make expander 24 and sleeve 23
Aprowl keep axiality.Square hole 233 can enable adjustable shelf 26 have short-range advance and retreat perpendicular to hole depth direction, also just make
Expanding block 25 can be in the radial expansion of tool.Before welding starts, regulating bolt 21 is unscrewed, and expanding block 25 inside contracts, and tool is with regard to energy
Through the inside of flange 12, thus tool and flange 12 can be allowed to be put into from below in the mouth of pipe of pipeline 11 together again；Work as tune
When section bolt 21 screws, expander 24 is descending and oppresses each expanding block 25 toward obliquely downward by tapering, and expanding block 25 will
Toward outside distending, until expanding block 25 peripheral contacts to pipeline 11 inwall；When regulating bolt 21 can not continue to tighten,
With regard to explanation expanding block 25 the distending of pipeline 11 to maximum, pipeline 11 is just presented closer to circular rotation body structure, and is managed
Road 11 can make tool and the coaxial line of pipeline 11 to the reaction force of expanding block 25, because flange 12 is on the basis of base 22,
The upper surface of base 22 is vertical with the axis of tool, so the position relationship of flange 12 and pipeline 11 is with regard to that can reach good coaxial
Degree and perpendicularity, the product structure after so welding more conform to use standard.
As shown in Figures 2 and 3, base 22 is provided with the ring seat 221 of an encirclement sleeve 23, and the inwall of ring seat 221 is close to
The outer wall of sleeve 23.Base 22 needs to play a part of to be to provide benchmark to flange 12, ensures the axis of pipeline 11 and flange 12
Plane perpendicular.But during positioning, because the mouth of pipe precision of pipeline 11 is often bad, this can make flange 12 occur axially partially
Difference, during regulating bolt 21 screws, flange 12 will cause base 22 crooked in turn, influence the core work(of tool
Energy.Increase ring seat 221 after, the bottom surface of flange 12 is limited by ring seat 221, and sleeve 23 can make ring seat 221 keep with
The vertical relation of the axis of sleeve 23, just because of the axis of sleeve 23 is related to the axis of pipeline 11, the upper surface of ring seat 221 is with turning over
The bottom surface on side 12 is related, so positioning precision more conforms to welding requirements.
As shown in Figures 2 and 3, the upper surface in tapering is fixed with suspension ring 241.Suspension ring 241 make positioning step hang tension state
Complete, pipeline 11 will be about to flange 12 certainly under gravity and compress, and facilitate worker's one-handed performance regulating bolt 21 to complete fixed
Position.
As shown in Fig. 2 expanding block 25 has three.Because can be toward mutually on the direction of hexagonal angle by three expanding blocks 25
Extend out, on the one hand make pipeline 11 be adjusted to the structure of rotational symmetry, the symmetrical center line of pipeline 11 and the center line of tool are with regard to energy
Reach conllinear, on the basis of the base 22 on tool, the bottom surface of flange 12 just can be vertical with the axis of pipeline 11, and guarantee has been welded
Perpendicularity after.It is obvious that when expanding block 25 is more than three, it can equally reach above effect.
As shown in figure 3, the inside of sleeve 23 is held in the return bullet that adjustable shelf 26 is located at one side in square hole 232 provided with two
Spring 27, return spring 27 make radial direction of the adjustable shelf 26 along sleeve 23 retreat.When regulating bolt 21 is unscrewed, tapering will loosen
To the active force of expanding block 25, in the presence of return spring 27, all expanding blocks 25 will inside contract automatically, avoid flange 12
Inwall, tool is facilitated to remove.
As shown in Fig. 2 the afterbody of regulating bolt 21 swells and is provided with annular knurl line.Ensure the precision of tool positioning, expansion
Block 25 needs have sufficiently large oppressive force to the inwall of pipeline 11, and it is very big that this requires that operation regulating bolt 21 will also have
Screw power.The afterbody that regulating bolt 21 swells can increase the arm of force, and annular knurl line can prevent from skidding, and so be advantageous for human hand pair
The increase torque of regulating bolt 21, has also just ensured the precision of coaxial positioning.
Above-described is only some embodiments of the present utility model.For the person of ordinary skill of the art,
On the premise of not departing from the utility model and creating design, various modifications and improvements can be made, these belong to this practicality
New protection domain.
