A kind of pipe docking scoring tool

Technical field

This utility model belongs to machinery scoring tool technical field, particularly relates to a kind of pipe docking scoring tool.

Background technology

Smelter ore dressing and the equipment of pipeline transportation industry, all vertical with the pipe of not equal-specification with circular same specification or Use after docking at a certain angle, install when changing, between institute's installation position pipe in docking or the damage that expires service life The location of mutual alignment, is usually after using tarred brown paper to its setting-out, re-uses the overall dimensions of model in the most required peace Carry out setting-out on holding position, cut with cutting machine or gas welding, when abutting joint, the accuracy of setting-out and the location of setting-out Accuracy, including the operation level of cutting, all can produce different errors to the quality of docking with location, and diameter is the biggest, angle When the most complicated pipe fitting, the time needed for setting-out and docking, the expense of lifting is the highest, brings the most not when this meeting is to operation Just with the waste of manpower and materials.

Utility model content

The purpose of this utility model is to provide a kind of pipe docking scoring tool, to solve present in existing ruling Setting-out accuracy is relatively low, Position location accuracy is poor, time-consuming longer the best the asking of pipe joint quality caused of complex pipes setting-out Topic.

For solving the problems referred to above, the technical solution adopted in the utility model is:

A kind of pipe docking scoring tool, including vertical chi and the adjustable ruler being connected on vertical chi, adjustable ruler connects location Bar, connection fixing clamp bottom vertical chi, two intermediate plate front ends of fixation clamp arrange clip tooth, and location bar is by sleeve with expansion link even Connecing, be provided with spring in expansion link, connect slide bar bottom expansion link, slide bar both sides are provided with two sliding sleeves, and sliding sleeve lower end connects respectively Needle guard, is provided with scriber in needle guard.

For this utility model is better achieved, the clip tooth of intermediate plate front end engages each other.

For this utility model is better achieved, spring is set in needle guard.

For this utility model is better achieved, adjustable ruler and slide bar arrange scale.

For this utility model is better achieved, sleeve lining has screw thread.

For this utility model is better achieved, sleeve lateral symmetry arranges handle.

For this utility model is better achieved, packing ring is set inside fixation clamp.

For this utility model is better achieved, vertical chi is vertical with adjustable ruler.

For this utility model is better achieved, slide bar is vertical with expansion link.

This utility model hinge structure has the advantages that

1, fixed folder structure is used, convenient installation, it is adaptable to Multiple Type, the docking of multiple angles pipe, fixation clamp two Clip tooth structure and the packing ring of the engagement of individual intermediate plate can ensure that the stability between fixation clamp and pipe.

2, expansion link and the interior spring arranged of needle guard, it is ensured that scriber intersects with pipe surface when line always, keeps away Exempt to draw partially and escape being classified.

3, two scribers are set and can improve the efficiency of line, it is ensured that joint is positive round shape.

4, the scale of adjustable ruler is easy to the determination of docking port home position, and improves its accuracy, and the scale of slide bar is easy to Scriber determines circumferential position, and accurately can quickly determine circumferential position according to different requirement of docking port.

Reference implication is as follows: 1, clip tooth；2, fixation clamp；3, pipe；4, packing ring；5, fixation clamp handle；6, vertical chi；7、 Bolt fixed by vertical chi；8, vertical chi sliding sleeve；9, adjustable ruler；10, adjustable ruler sliding sleeve；11, adjustable ruler fixes bolt；12, location bar； 13, sleeve；14, handle；15, expansion link；16, sliding sleeve；17, fixing bolt；18, slide bar；19, needle guard；20, scriber.

Detailed description of the invention

The utility model is described in further detail with detailed description of the invention below in conjunction with the accompanying drawings.

A kind of pipe docking scoring tool as shown in Figure 1, including orthogonal vertical chi 6 and the tune being connected on vertical chi 6 Joint chi 9, adjustable ruler 9 arranges scale, and connection fixing clamp 2 bottom vertical chi 6, two intermediate plate front ends of fixation clamp 2 are arranged mutually nibbles The clip tooth 1 closed, arranges packing ring 4 inside fixation clamp 2, adjustable ruler 9 connects location bar 12, and location bar 12 passes through sleeve 13 with flexible Bar 15 connects, and sleeve 13 inwall has screw thread, and sleeve 13 lateral symmetry arranges handle 14, is provided with spring in expansion link 15, flexible Bottom bar 15, vertical connection slide bar 18, slide bar 18 arranges scale, and slide bar 18 both sides are provided with two sliding sleeves 16, and sliding sleeve 16 lower end is divided Not Lian Jie needle guard 19, spring is set in needle guard 19, spring inner is provided with scriber 20.

Before pipe docking line work, first being closed up by fixation clamp handle 5, pipe clamped by two intermediate plates opening fixation clamp 2 3, relieving fixation clamp handle 5 makes the clip tooth 1 of two intermediate plates of fixation clamp 2 engage each other fixing pipe 3, utilizes packing ring 4 to prevent solid Clamp 2 and pipe 3 slide；The adjustable ruler sliding sleeve 10 being socketed on adjustable ruler 9, adjusts location bar according to the scale on adjustable ruler 9 The position of 12, makes location bar 12 be positioned at above the home position needing picture circle, screws the adjustable ruler coordinated with adjustable ruler sliding sleeve 10 Fixing bolt 11, secured adjusted chi sliding sleeve 10；Adjust two sliding sleeves 16 respectively according to the scale on slide bar 18, make two scribers 20 The fixing bolt 17 supporting with sliding sleeve 16 is screwed after laying respectively at circumferential position；The vertical chi sliding sleeve 8 that slides drive adjustable ruler 9 move down from And regulating the height of scriber 20, the spring being adjusted in expansion link 15 and needle guard 19 is compacted, and scriber 20, will be with after pipe 3 The vertical chi that vertical chi sliding sleeve 8 coordinates is fixed bolt 7 and is screwed, and makes adjustable ruler 9 be fixed on vertical chi 6.

During pipe docking line work, the handle 14 on turnbarrel 13, make sleeve 13 rotate under handle 14 acts on, band Moving slide-bar 18 rotates, and makes scriber 20 rule at cylinder 3 surface pivots, when scriber 20 is positioned at cylinder 3 contact surface peak, flexible Spring in cylinder 15 and the spring in needle guard 19 are in impaction state, along with the rotation of slide bar 18, drive two scribers 20 simultaneously Leaving cylinder 3 contact surface peak, the spring in cylinder 3 both sides landing, expansion link 15 and needle guard 19 is along with scriber 20 position Reduction gradually loosen, control scriber 20 be constantly in pipe 3 surface, after scriber 20 reaches pipe 3 both sides minimum point, scriber 20 start to move to cylinder 3 contact surface peak under slide bar 18 drives, and the spring that scriber 20 extrudes in needle guard 19 gradually tightens up, And extruding slide bar 18 moves upward simultaneously, drive expansion link 15 inner spring to tighten up, control scriber 20 and be still constantly in pipe 3 table Face, until two scribers 20 return to cylinder 3 contact surface peak, draws and has justified.
