Embodiment
The present invention is made up of blade 1, digital display centimeter 2, vernier seat 3, fixed block 4, bar card 5, U-shaped calibration block 10.
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 digital display centimeter 2 is installed with vernier seat 3 and is connected, and digital display centimeter 2 is by dial gauge gauge outfit, measurement pin
11st, adapter sleeve is constituted.Dial gauge gauge outfit is connected with measurement pin 11 upper end, and measurement pin 11 is arranged on vernier seat 3 by adapter sleeve
On, the distance on the measurement head of pin 11 to blade 1 is more than the bottom of fixed block 4 to 8 ~ 10mm of distance of blade 1.
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.
