Specific embodiment
A kind of grating sensor caliberating device as shown in Figure 1, including base 1, grating sensor 8 and differential
6, support post 3 is installed on the base 1, Height Adjustable lower 4 He of measurement support arm is installed on the support post 3
Height Adjustable upper measurement support arm 5, described lower measurement support arm 4 with upper measurement support arm 5 parallel and upper measurement support arm 5 be located at lower survey
Amount support arm 4 above, the grating sensor 8 be vertically arranged to lower measurement support arm 4 on and grating sensor 8 probe
9 upward, the differential head 6 be installed on measurement support arm 5 and differential head 6 measuring staff 7 down, the measuring staff 7 is being located at probe 9 just
Top.
In the present embodiment, on the lower measurement support arm 4 and upper measurement support arm 5, set lever 2 is provided with.
In the present embodiment, the support post 3 is fixedly installed on base 1.
The operation principle of device of the present utility model is：During the process of measurement grating sensor 8, will probe 9 and survey
Bar 7 is just contacted, and slow rotation differential head 6 clockwise, measuring staff 7 will decline compression probe 9, the process indicating value of probe 9
Compared with the process indicating value of differential head 6, you can verify the process precision of grating sensor 8.Measurement grating micrometer sensing
During the backhaul of device 8, probe 9 is compressed to maximum range on measuring staff 7, counterclockwise slow rotation differential head 6, measuring staff 7 will be gone up
