There is strip hole at above-mentioned portable bar stock bent degree laser measuring apparatus, the center of the vernier seat and fixed block respectively, Strip hole matches with blade cross sectional shape, and vernier seat and fixed block are sleeved on blade by strip hole.
There is spring vertically downward above-mentioned portable bar stock bent degree laser measuring apparatus, the top both sides of the bar card Hole, spring eye embeds shock mount, and the upper end of spring lever withstands on the lower end of spring, the lower end of spring lever and the upper end phase of V-type neck Connection.
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, U-shaped school The depth of U-type groove in the middle of quasi- block is equal with the distance of fixed block bottom to blade bottom.
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 Coordinate, there is fixed block clamping screw 9 to fix fixed block 4 with blade 4 in the top of fixed block 4.Filled between fixed block 4 and blade 1 There is pad, it is ensured that the easy slide of fixed block 4.
Fig. 1,2 displays, top and the assembly connection of fixed block 4 of two bar cards 5, the bottom of two bar cards 5 is respectively The V-type neck 6 that Open Side Down.There is spring eye vertically downward the top both sides of bar card 5, and spring eye embeds shock mount, spring The upper end of bar 7 withstands on the lower end of spring, and the lower end of spring lever 7 is connected with the upper end of V-type neck 6.
