Above-mentioned portable bar stock bent degree laser measuring apparatus, it also has U-shaped calibration block, and U-shaped calibration block is U-shaped piece, and the degree of depth of the U-type groove in the middle of U-shaped calibration block is equal with the distance bottom fixed block bottom blade.
The invention has the beneficial effects as follows:
The fixed block at blade two ends of the present invention and bar aligned contact, laser range sensor in the middle of blade is found range to Surface of Rod Bar, range measurement can demonstrate the flexibility of bar, flexibility accuracy of detection can meet every meter of flexibility 0.1mm, and by laser range sensor feedback the positive and negative bending direction that can judge steel fast of numerical value.Structure of the present invention is simple, measurement is accurate, one man operation can be realized, every meter of flexibility can not only be measured, the flexibility between bar 200 ~ 1000mm can be measured by mobile fixed block and bar card, and the flexibility of the deformed steel of plane, cambered surface can also be had to measure to sheet material, tubing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the A-A cut-open view of Fig. 1;
Fig. 3 is the structural representation of U-shaped calibration block.
In figure, mark is as follows: blade 1, laser range sensor 2, vernier seat 3, fixed block 4, bar card 5, V-type draw-in groove 6, spring lever 7, vernier seat clamping screw 8, fixed block clamping screw 9, U-shaped calibration block 10.
Embodiment
The present invention is made up of blade 1, laser range sensor 2, vernier seat 3, fixed block 4, bar card 5, U-shaped calibration block 10.
Fig. 1 shows, there is strip hole at vernier seat 3 center, and strip hole and blade 1 cross sectional shape match, and vernier seat 3 is sleeved on blade 1 by strip hole, vernier seat 3 and blade 1, for being slidably matched, have vernier seat clamping screw 8 vernier seat 3 and blade 1 to be fixed above vernier seat 3.Between vernier seat 3 and blade 1, pad is housed, ensure the easy slide of vernier seat 3, blade 1 is marked with a centimetre unit scales.
Fig. 1 shows, and laser range sensor 2 is fixedly mounted on the bottom of vernier seat 3.
Fig. 1 shows, two fixed blocks 4 are rectangular parallelepiped, there is strip hole at the center of two fixed blocks 4 respectively, strip hole and blade cross sectional shape match, fixed block 4 is sleeved on the two ends of blade 1 by strip hole, two fixed blocks 4 and blade 1, for being slidably matched, have fixed block clamping screw 9 fixed block 4 and blade 4 to be fixed above fixed block 4.Between fixed block 4 and blade 1, pad is housed, ensures the easy slide of fixed block 4.
