Background technology
Wedge component utilizes the functional relation of wedge relative rotation and the generation deviation angle in light path, to realize that optical system is big The scan function of visual field, scan efficiency is high, compact-sized, has in lightweight on-board optical system assembling field and widely should Use prospect.With " two autocollimators, a Precise Angle-measuring Table, a frock speculum, a wedge seat connecting tooling are built One wheel measuring platform, utilizes the two-sided autocollimatic picture of wedge to carry out accurate adjustment " method, do not influencing the premise of Product Precision Under, improve work efficiency, reduce assembly cost.Before having a wide range of applications in lightweight on-board optical system assembling field Scape.
The content of the invention
Technical problems to be solved
In order to avoid the shortcomings of the prior art, the method that the present invention proposes a kind of double wedges of adjustment, can extensive use In the adjustment of various double wedge components, future has broad application prospects.
Technical solution
A kind of method of the double wedges of adjustment, it is characterised in that：The both sides of Precise Angle-measuring Table are placed in two autocollimators, Accurate adjustment is carried out using the two-sided autocollimatic picture of wedge, step is as follows：
Step 1：Positioned at the both sides for placing wedge turntable, the optical axis included angle for adjusting two autocollimators is two autocollimators First wedge point of theory；
Step 2：First wedge optical axis is vertical with turntable shaft, and the first autocollimator of adjustment finds the first of the first wedge Face auto-collimation picture；Adjust the second face auto-collimation picture that the second autocollimator finds the first wedge, meet two autocollimatic pictures with each The deviation of graticle cross searching all≤5 ', fixes the first wedge；
Step 3：The second autocollimator original state is kept, the second wedge is placed in the microscope base containing the first wedge, is rotated Turntable causes the second wedge to rotate, and the angle of rotation is the wedge of the wedge of deflection angle+the second of the wedge of the angle of wedge+the first of the first wedge Angle so that the second autocollimator finds the second face auto-collimation picture of the second wedge；
Step 4：Second the second face of wedge and deviation≤5 ' of the second autocollimator graticle cross searching are adjusted, fixes Two wedges.
Beneficial effect
