Embodiment
The present invention is described in further detail with reference to specific embodiment.
As shown in Figure 1 to Figure 3, the present invention is a kind of coaxial localization tool of flange pipeline, including with tapering and cylinder portion
Expander 24 and the regulating bolt 21 penetrated from cylinder portion rear, are cased with sleeve 23, sleeve between expander 24 and regulating bolt 21
23 provided with the cavity 231 penetrated for cylinder portion and around the uniform some square holes 233 of cavity 231, between expander 24 and sleeve 23
The expanding block 25 of the correspondence quantity of square hole 233 is clamped with, each expanding block 25 has on the conical surface with taper fit, expanding block 25
The adjustable shelf 26 of a perpendicular type is fixed with, the one side of adjustable shelf 26 is fixed with expanding block 25, another side penetrates square hole 233 and can edge
The radial motion of sleeve 23, sleeve 23 is fixed with the base 22 of dish-type in the one side close to regulating bolt 21.The axis of tool with
The axis collinear of the axis of expander 24, the axis of sleeve 23 and base 22.Cavity 231 can make expander 24 and sleeve 23 in work
Axiality is kept in dynamic.Square hole 233 can enable adjustable shelf 26 have short-range advance and retreat perpendicular to hole depth direction, also just make expansion
Block 25 can tool radial expansion.Before welding starts, unscrew regulating bolt 21, make expanding block 25 inside contract, tool is with regard to that can wear
The inside of flange 12 is crossed, 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 regulation
When bolt 21 is screwed, expander 24 is descending and oppresses each expanding block 25 toward obliquely downward by tapering, and expanding block 25 will be past
Outside distending, until expanding block 25 peripheral contacts to pipeline 11 inwall；When regulating bolt 21 can not continue to tighten, just
Illustrate expanding block 25 the distending of pipeline 11 to maximum, pipeline 11 is just presented closer to circular rotation body structure, and pipeline
The reaction force of 11 pairs of expanding blocks 25 can make tool and the coaxial line of pipeline 11, because flange 12 is on the basis of base 22, bottom
The upper surface of seat 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 axiality
And perpendicularity, so weld after product structure more conform to use standard.
As shown in Figures 2 and 3, ring seat 221 of the base 22 provided with an encirclement sleeve 23, 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, it is ensured that the axis of pipeline 11 and flange 12
Plane perpendicular.But during positioning, because the mouth of pipe precision of pipeline 11 is not often good, this can make flange 12 occur axially partially
Difference, during regulating bolt 21 is screwed, 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 workman'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 rotationally symmetrical structure, the symmetrical center line of pipeline 11 and the center line of tool are with regard to energy
Reach that collinearly 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, it is ensured that has welded
Perpendicularity after.It is obvious that when expanding block 25 is more than three, can equally reach above effect.
As shown in figure 3, the inside of sleeve 23 is held in return bullet of the adjustable shelf 26 positioned at one side in square hole 232 provided with two
Spring 27, return spring 27 makes 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 be inside contracted automatically, avoid flange 12
Inwall, facilitates tool 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 this requires operative's regulating bolt 21 will also have very big
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 invention.For the person of ordinary skill of the art, not
On the premise of departing from the invention design, various modifications and improvements can be made, these belong to the protection model of the present invention
Enclose.
