Embodiment
Technical scheme is illustrated with embodiment below in conjunction with the accompanying drawings.
As shown in Figures 1 to 4, a kind of accurate bended pipe curvature measurement device of the present invention, including pedestal 6, base
6 upper surfaces of seat are provided with groove 4, and pipe measuring scale is provided with groove 4, and pipe measuring scale includes pipe measuring scale 1, fixed circle
Pipe measuring scale 2 and pipe measuring scale 23, the side of groove 4 are provided with horizontal scale bar 5, are provided with groove 4 and fixed pipe measuring scale
The 2 horizontal scale chi zero mark lines 7 being correspondingly arranged, what pipe measuring scale 1 can move left and right is located at fixed pipe measuring scale 2
Side, the opposite side located at fixed pipe measuring scale 2 that pipe measuring scale 23 can move left and right.This hair of composition described above
Bright basic structure.
Structure setting as present invention use, by being provided with groove 4 in the upper surface of pedestal 6, pipe is provided with groove 4
Measuring scale 1, fixed pipe measuring scale 2 and pipe measuring scale 23, by measuring spacing and steel between adjacent pipe measuring scale
The bending height of pipe 20 is poor, then by the calculation with Pythagorean theorem, can quickly calculate the curvature of steel pipe 20, the letter of its structure
Single, easy to operate, registration, reading are quick, operating efficiency is high.
More specifically, the pipe measuring scale by outer tube 8 and inner tube 9 socket form, the top of inner tube 9 be provided with it is adsorbable in
Rotatable magnet cap 11 on steel pipe 20, inner tube 9 are provided with inner tube scale 10, and inner tube 9 is moving up and down to be located at outer tube 8
Interior, the bottom of outer tube 8 coordinates in groove 4.Using such structure setting, steel tube body is adsorbed in by rotating magnet cap 11
On, then reading is carried out in the inner tube 9 for passing through pipe measuring scale, it is poor so as to obtain the bending height of steel pipe 20.
More specifically, the pedestal 6 uses prismatoid structure setting.
A kind of accurate bended pipe curvature measurement device, its specific measuring process are as follows：
Step 1, reference picture 2, after the steel pipe 20 of bending is stably placed in frock 21, curvature measurement device is put
Put and bend pipe underface, it should be noted that horizontal scale chi is horizontal with steel pipe longitudinal axis；
Step 2, along axis trimming curvature measurement setting position, make to fix steel pipe 20 of the pipe measuring scale 2 in alignment with bending
Center, inner tube 9 is pulled out, the magnet cap 11 on the end of inner tube 9 is adsorbed in the bottom of steel pipe 20, read the correspondence of fixation measuring chi 2
Scale, with K2As reading；
Step 3, pipe measuring scale 1 is moved respectively with pipe measuring scale 23 to required position, magnet cap 11 is inhaled
The bottom of steel pipe 20 is invested, scale corresponding to pipe measuring scale 1 is read, with K1As reading, and read 23 pairs of pipe measuring scale
The scale answered, with K3As reading；
Step 4, while the spacing between now pipe measuring scale 1 and fixed pipe measuring scale 2 is read, with L1As
Reading, and the spacing between fixed pipe measuring scale 2 and pipe measuring scale 23 is read, with L2As reading；
Step 5, reference picture 1 calculate local curvature and overall curvature, theoretical calculation principle is L according to Pythagorean theorem2+
