At work, the first electric displacement sensor 6 first and the second electric displacement sensor 7 measure its respectively end face are arrived respectively
The distance of 4 end face of fixation kit, will be in the distance data transmission to controller that measured.After controller compares two range data,
It controls the first briquetting (the second briquetting) held at a distance not move, the second briquetting of short distance end (the first briquetting) pushes fixation kit
4 slidings, the distance that fixation kit 4 slides are that distal end distance subtracts half of the proximal end apart from resulting value.
Since error is in the presence of that can exist, first motor 81 and the second motor 82 push away there are distance and mostly and not shift two kinds of position onto
Situation.When not shifting onto, that is, repeat above-mentioned step.If distance pushes away mostly, using former distal side as proximal end, continue weight
Multiple above-mentioned step, until the numerical value of two distances is equal, then 6 He of the end face of fixation kit 4 and the first electric displacement sensor at this time
The end face ideal parallelism of second electric displacement sensor 7.
Then, then manually magnetic support 12 is adsorbed onto on the corresponding position of bearing 1, so that micrometer probe 9 is touched plane flat
At the maximum horizontal diameter of crystalline substance 5, the registration of micrometer is 0 μm or so (being no more than 2 μm), you can starts to control air supporting upper slide unit 3
Sliding measures the straightness of guide rail 2.
Above disclosed is only a kind of the utility model preferred embodiment, cannot limit this practicality with this certainly
Novel interest field, therefore equivalent variations made according to the claim of the utility model still belong to what the utility model was covered
Range.
