Description
Technical field
The present invention relates to a kind of angle of bend positioning devices.
Background technology
Industrial pipes are mainly used for fluid conveying, industry has the connection for pressing the pipelines such as equipment, the performance and quality of product straight
Connect the excellent difference of the transfer efficiency and equipment that are related to pipeline.Therefore, industrial pipes are in shape design, manufacture craft, safety
Detection etc. has extremely strict requirements.In industrial pipes, elbow is a kind of important component, its outer diameter, wall thickness,
The quality of the quality of internal diameter etc. determines the quality of entire industrial pipes quality.
Currently, the outer arc and inner arc of measurement elbow generally use bevel protractor, but bevel protractor is inconvenient to use, needs every time
It adjusts, such mode has delayed many times, reduces working efficiency.Traditional elbow scribing line angle position inaccurate,
The problems such as pipe is difficult to install, welding quality is not high, and tradition scribing line angle localization method work are easy tod produce in follow-up work
Make inefficiency.Therefore, the accuracy for improving elbow scribing line angle is necessary.
Traditional angle localization method is mainly the length for measuring outer arc in sizing elbow, calculates sizing elbow needed for decile
The number of degrees, then using tape measure, connection is crossed from both sides, and scribing line in this way is intermediate and no fixed since line segment span is big and is bent
Position, the cutting line to the left or to the right that all can not accurately draw required angle elbow.
Scribing line angle position inaccurate is easy for leading to the problem of as follows：
1) angle is inaccurate, and sizing angle of bend inaccuracy caused by scribing line is inaccurate is to install after causing pipe to make
It is difficult.
2) it shapes end face of elbow out of plumb, just will produce connector bend and connect that gap is excessive or too small, and gap is non-uniform
Situation easy tos produce problems of welded quality.
3) sizing elbow tangential length is inaccurate, and amount arc length draws the tangential length that angle cannot be guaranteed sizing elbow, and it is fixed to generate
The case where type elbow tangent line shortens, since the allowable range of error of school pipe is ± 3mm, and the sizing elbow tangential length cut is super
Allowable range is gone out, this just makes made pipe too short.Cause pipe on ship difficult to install, such as blanking has resulted in pipe again
The waste of material.
4) method of lost labor, tradition scribing line want two people's cooperations that could carry out, and standardized sizing elbow wants 10 minutes,
Two people are exactly 20 minutes, are wasted time.
Invention content
The technical problem to be solved by the present invention is in order to overcome angle of bend position inaccurate in the prior art, need it is more
People, which co-operates, leads to the lower defect of working efficiency, provides a kind of angle of bend positioning device.
The present invention is to solve above-mentioned technical problem by following technical proposals：
A kind of angle of bend positioning device, including bearing panel, angle positioning rule and scribing line locator, the bearing panel

The positioning of scribing position.
Preferably, the angle of bend positioning device further includes elbow supporting rack, the elbow supporting rack is set to described
The end face close to the scribing line locator of bearing panel, the elbow supporting rack are used to support the elbow.
Preferably, the angle of bend positioning device further includes the first limited screw, first limited screw is used for will
The angle positioning rule is fixed with the bearing panel.By being fixed at the angle index of elbow to angle positioning rule,
It can be more convenient to carry out scribing line positioning to elbow.
Preferably, the angle of bend positioning device further includes length positioning baffle and the second limited screw, the length
Positioning baffle is slidedly arranged in the angle positioning rule, and second limited screw is used for the length positioning baffle and the angle
Degree positioning rule is fixed, and the angle positioning rule is equipped with length scale.
On the basis of common knowledge of the art, above-mentioned each optimum condition can be combined arbitrarily to get each preferable reality of the present invention
Example.
The positive effect of the present invention is that：The present invention angle of bend positioning device can to elbow cross angle into
Row is accurately positioned, and only needs people's operation, easy to operate, improves work efficiency.
Description of the drawings
Fig. 1 is a preferred embodiment of the present invention the structural schematic diagram of angle of bend positioning device.
