Specific implementation mode
As shown in FIG. 1 to 3, raster pattern lever micrometer sensor provided in this embodiment include measuring rod 1, rotating member 2,
Dust cap 3, main body 5, cover board 6, carriage, scale grating 11, measures seat 12, indication grating 13, electro-optical package 14, electricity at briquetting 4
Road plate 15, dovetail guide 16, tension spring 17 and hanging bolt 18, the carriage include that 9, four V-type rails of upper saddle 7, two are secondary
Crossed roller 8 and lower slider 10, lower slider 9 are fixed in main body 5, and two V-type rails 7 in four V-type rails are fixed on
In the cavity of slide 9, another two V-type rail 7 is fixed on lower slider 10, and crossed roller 8 is located at the V-type of upper and lower V-type rail 7
In slot, the side of upper saddle 9 is provided with two precompressed adjusting screws, makes upper saddle 9 and lower slider 10 by precompressed adjusting screw
Accurate crossed roller linear motion pair is formd, which has mobile and guide function, can make 11 He of scale grating
It measures seat 12 and in one plane makees linear relative movement always.The tension spring 17 is located on upper saddle 9, and one end of which is fixed on pressures
On block 4, the other end is fixed on by hanging bolt 18 in main body 5.
The non-measured end of the measuring rod 1 is connect by screw-thread fit with one end of rotating member 2, the other end of rotating member 2
Between briquetting 4 and upper saddle 9, briquetting 4 is bolted with upper saddle 9, and rotating member 2 is pressed in briquetting 4 by bolt in advance
Between upper saddle 9, rotation dynamics is more than measuring force.
