Description
Technical field
The present invention relates to optical precision instrument fields, and in particular to a kind of optics microscope group pressing ring disassembly for preventing mirror surface from scratching
Device and eyeglass method for dismounting.
Background technique
Optical lens is usually made of multiple microscope groups, to guarantee that optical lens has excellent image quality, in adjustment
Cheng Zhong, in addition to guaranteeing each microscope group light axis consistency, it is necessary to guarantee the microstress assembly of lens in each microscope group, the micro- of lens answers
Power assembly is an important link in optical lens assembly, while being also a difficult point.
Microscope group structure as shown in Figure 2, wherein lens 11 are gap-matched with microscope base 13, first by lens 11 when assembly
It is packed into microscope base 13, then screws in pressing ring 14.To guarantee the microstress assembly of optical lens, while vibration, impact can be adapted to
Etc. operating conditions, it is locking before screwing in pressing ring 14 to apply a little silica gel on 14 external screw thread of pressing ring, then again by 13 outer circle glue of microscope base
Silica gel is injected with fixing len in hole.Nonetheless, the change of lens face shape deflection usually can be also caused because of erection stress and Optical finishing
Difference eventually results in entire lens imaging quality and is deteriorated.At this point, only way is exactly to remove the lens 11 of face deformation difference,
Re-start microstress assembly.The first step that lens 11 are dismantled is the disassembly of pressing ring 14, as previously mentioned, the pressing ring 14 of lens group revolves
It is coated with silica gel on external screw thread before entering microscope base 13, pressing ring 14 is screwed out at this time and have to apply sufficiently large torque (especially mouth
Diameter is greater than 100 millimeters of eyeglass), this process easily causes the scuffing of eyeglass mirror surface.
Currently used microscope group method for dismounting has two kinds, the first is to use commonly to tear open without positioning pressing ring spanner progress microscope group
It unloads, spanner is caught in pressing ring card slot when disassembly, and during screwing out pressing ring, spanner easily deviates from card slot and causes drawing for optical mirror plane
Wound；Second method is that destructive dismounting is carried out using machining, and such as microscope group pressing ring vehicle is fallen or cut using lathe, milling machine
Disconnected, to destroy Structure of Mechanical Parts as cost, the chip on the one hand generated in processing is easy to scratch mirror surface, greasy dirt meeting this method
Mirror surface is caused to pollute, the breakage of another aspect mechanical structure parts must re-work, and delay manufacturing schedule and increase and be produced into
This.
