Description
Technical field
Provided by the utility model is the supplemental measurement tool of fields of measurement, is particularly suitable for general NC bending machine upper tube
Material bending angle is quick and precisely measured and is tracked.Specifically tubing cold bend(ing) angle measurement unit.
Background technology
Currently, bending pipes angle measurement generally use following methods：
（1）Common angle ruler or Digit Display Angle Ruler is directly used to measure；
（2）It is measured using three-coordinates measuring machine.
But above two kinds of methods are all in place of Shortcomings, be widely used in daily production it is direct measured with bevel protractor,
Measurement error is larger, and measurement data is influenced by external factor, is not used to analysis tubing bending angle deforming high precision research, by
In blocking for tube bending machine mould, causes bevel protractor accurately to be measured tubing in bending process, miss by a mile；And utilize three
Coordinate measuring apparatus measurement accuracy is higher, but use cost is high and cumbersome, it is difficult to be widely used in actual production.
Invention content
The purpose of this utility model is that when tubing is through bending machine bending machining, to confirm its bending angle extent of deviation,
Bending angle measurement is carried out under the premise of not removing tubing.The utility model can measure tubing bending angle on bending machine in real time
The advantages of spending, taking into account bevel protractor directly measurement and three-coordinates measuring machine, solves nothing during conventional method tubing angle measurement
The technical issues of precision that method avoids is low and measured deviation has no way of grasping.
Scheme is used by the utility model solves technical problem：
Two layers of frame tube bending connection reticular structure are equipped in the upper vertical of bending tubing, upper frame pipe passes through threeway
Connector connects into the horizontal outer rim with bending angle, and bending angle both sides top outer rim is respectively equipped with as carrying angle
The angle steel of ruler card slot, lower part connect into bending angle structure equipped with frame tube by four-way connection transverse and longitudinal；
It is equipped with single active section casing shaft in top, lower knuckle angle or can axially move up and down with scale
The shaft of ruler, bending angle are hung with plummet vertical from up to down and bending tubing centering；
Two layers of frame tube lower part vertically fit in swan-neck equipped with vertical frame pipe by circular arc type card base or V-type card base
Material is fastened in vertical frame tube by the connection of card base hold-down bolt on V-type card base.
Good effect, due to bent angular measurement position translation when the utility model is using by tubing clod wash, not by other
The position march angular measurement of object interference.Overall framework is connected using small-bore carbon steel pipe, and the crossbeam longeron of frame is using letter
Easy threeway, four-way connection are attached；Ensure when bevel protractor installation place is equipped with angle steel card slot, angle steel and frame welding and accurately angle
The depth of parallelism of steel and frame；It is attached using barrel forms at bending pipes, casing spindle central can hang plummet, when use
Position centering；Card base improves the smoothness and accuracy that the utility model uses when being bonded with tubing with groove.Equipped with accidentally
Poor compensation mechanism, can it is convenient, accurately measure bending pipes angle in bending process.Suitable for as tubing cold bend(ing) angle
Measuring device.

Specific implementation mode
According to the figure, two layers of bending connection reticular structure of frame tube 3, upper frame are equipped in the upper vertical of bending tubing
Pipe connects into the horizontal outer rim with bending angle by three-way connection 5, and bending angle both sides top outer rim is respectively equipped with
As the angle steel 2 of carrying bevel protractor card slot, lower part connects into bending angle structure equipped with frame tube by 4 transverse and longitudinal of four-way connection；
It is equipped with single active section casing shaft 1 in top, lower knuckle angle or axial can move up and down carries quarter
The shaft 1.1 of ruler 1.2 is spent, bending angle is hung with plummet 6 vertical from up to down and bending tubing centering；
Two layers of frame tube lower part are vertically fitted in equipped with vertical frame pipe by circular arc type card base 7 or V-type card base 7.1 curved
Curved tube material is fastened in vertical frame tube by the connection of card base hold-down bolt 7.2 on V-type card base.
The operation principle of the utility model：
Lower frame pipe bends angle first, then measures actual angle with bevel protractor, is recorded as point of theory, reuses this
Utility model carries out tubing angle measurement, is recorded as actual angle, two groups of data differences are finally depicted as line chart.
Then the utility model can be used directly to measure the bending angle of tubing, directly by card base and tubing when measurement
Fitting, and read the bevel protractor number of degrees.
The number of degrees finally read with the utility model, are compareed with the line chart drawn before, measure data
Error compensation is both final bending angle.
Utility model works process：
1., the utility model is put in platform first, using horizon rule by angle steel plane leveling.
2., the utility model is subjected to error test, tested by a series of measurements, form the utility model and making
The Error Trend generated in journey.
3., the pipe for needing clod wash bent on bending machine.
4., the utility model is positioned on pipe after bending, and read on the bevel protractor above the utility model
Bending angle.
5., the Error Trend that experiment generates before control, error compensation, final degree of certainty are carried out to the number of degrees measured
Number.
