The beneficial effects of the invention are as follows：
The fixed block at the blade two ends of the present invention is contacted with bar positioning, and the laser range sensor in the middle of blade is to bar
Surface carries out ranging, and distance measurement result can show the flexibility of bar, and flexibility accuracy of detection can meet every meter of flexibility
0.1mm, and the numerical value that can be fed back by laser range sensor is positive and negative can quickly judge the bending direction of steel.Present invention knot
Structure is simple, measurement is accurate, it is possible to achieve one man operation, can not only measure every meter of flexibility, passes through mobile fixed block and bar
Card can measure the flexibility between 200 ~ 1000mm of bar, to sheet material, tubing and can also have plane, the deformed steel of cambered surface
Flexibility is measured.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is Fig. 1 A-A sectional views；
Fig. 3 is the structural representation of U-shaped calibration block.
Marked in figure as follows：Blade 1, laser range sensor 2, vernier seat 3, fixed block 4, bar card 5, V-type neck
6th, spring lever 7, vernier seat clamping screw 8, fixed block clamping screw 9, U-shaped calibration block 10.
Embodiment
The present invention is by blade 1, laser range sensor 2, vernier seat 3, fixed block 4, bar card 5,10 groups of U-shaped calibration block
Into.
Fig. 1 shows that there is strip hole at 3 centers of vernier seat, and strip hole matches with the cross sectional shape of blade 1, and vernier seat 3 passes through length
Bar borehole jack is on blade 1, and vernier seat 3, to be slidably matched, has vernier seat clamping screw 8 will with blade 1 in the top of vernier seat 3
Vernier seat 3 is fixed with blade 1.Pad is housed between vernier seat 3 and blade 1, it is ensured that the easy slide of vernier seat 3, blade 1 is marked with
Centimetre unit scales.
Fig. 1 shows that laser range sensor 2 is fixedly mounted on the bottom of vernier seat 3.
Fig. 1 shows that two fixed blocks 4 are cuboid, and there are strip hole, strip hole and chi in the center of two fixed blocks 4 respectively
Body cross sectional shape matches, and fixed block 4 is sleeved on the two ends of blade 1 by strip hole, and two fixed blocks 4 are slip with blade 1
