The accurate measurement for realizing small gaps straightness and flatness can be facilitated with auxiliary device, traditional slit is overcome using this method
The defects of measurement method, improves measurement accuracy and efficiency, ensure that the reliability service of slit kind equipment.
In order to solve the above technical problems, small gaps straightness of the present invention and the auxiliary device of the measurement of planeness include ladder
Measuring block and circular ring shape measurement terminal, the measurement terminal are arranged on the upper plane of the Step measurement block, the Step measurement block
The flatness of lower plane is less than 0.01mm, and the flatness of the cascaded surface of the Step measurement block is less than less than 0.01mm, verticality
0.01mm。
The measuring method of small gaps straightness and flatness includes the following steps：
Step 1: the Step measurement block of auxiliary device is assigned in slit, lower plane and the slit institute of Step measurement block
The flat face that need to be measured touches, and the cascaded surface of Step measurement block is resisted against slit outer end face, and the target of optical measuring apparatus is pacified
It is put in circular ring shape measurement terminal；
Step 2: gathering the parameter of target by optical measuring apparatus, Step measurement block is slided into simultaneously rank along slit end face
Tread is close to slit end face, gathers parameter of the target in each measuring point of slit measuring surface respectively by optical measuring apparatus, to complete
Each measuring point data acquisition of slit measuring surface；
Step 3: each measuring point data of slit measuring surface of acquisition is simulated, analyzed and counted by optical measuring apparatus
It calculates, obtains straightness, the plane degrees of data of slit measuring surface.
Since the measuring method of small gaps straightness of the present invention and flatness employs above-mentioned technical proposal, i.e. this auxiliary
The measurement terminal of device is arranged on the upper plane of Step measurement block, and the flatness of Step measurement block lower plane is less than 0.01mm, ladder
The flatness of the cascaded surface of measuring block is less than 0.01mm, verticality is less than 0.01mm.This measuring method assigns Step measurement block
In slit, the flat face of measurement touches needed for Step measurement block lower plane and slit, cascaded surface is resisted against slit outer end face, will
Target is placed in circular ring shape measurement terminal；Target parameter is gathered using optical measuring apparatus, by Step measurement block along slit ends
Face is slided, and gathers parameter of the target in each measuring point of slit measuring surface respectively by optical measuring apparatus, and it is each to complete slit measuring surface
Measuring point data gathers；Each measuring point data of slit measuring surface of acquisition is simulated, analyzed and calculated by optical measuring apparatus,
Obtain straightness, the plane degrees of data of slit measuring surface.This auxiliary device, which can facilitate, realizes small gaps straightness and flatness
Accurate measurement, the defects of this method overcomes traditional slit measurement method, improve measurement accuracy and efficiency, ensure that slit
The reliability service of kind equipment.
