The upside of eyeglass 4 304, the pressure-bearing of eyeglass 2 302 is in the upside of eyeglass 3 303, and the bottom pressure-bearing of eyeglass 1 is in positioning base
The upside of standard 2 202, the upside of eyeglass 1 is limited on lens barrel 402 by trim ring 401, the level of the positioning datum 2 202
Highly it is more than the height after eyeglass 2 302 is installed, is separated by 0.2mm gaps between the eyeglass 1 and eyeglass 2 302；Set
The gap purpose for having 0.2MM is to ensure that the pressure-bearing of eyeglass 1 on positioning datum 2 202, it is to avoid eyeglass 2 302 and eyeglass one
301 in formal dress mutual pressure-bearing；Eyeglass one can be effectively prevented on positioning datum 2 202 using by the pressure-bearing of eyeglass 1
301 tilt, and make lens imaging quality more secure, improve traditional pressure-bearing of eyeglass 1 on the sphere of eyeglass 2 302
Mounting means, overcomes the thick very little in the side of eyeglass 1 and tilts the defect not ensured completely；
The spacer ring 3 403 is arranged on the downside of eyeglass 4 304, and the pressure-bearing of spacer ring 3 403 is on eyeglass 5 305, eyeglass
5 305 pressure-bearings are on spacer ring 4 404, and the pressure-bearing of spacer ring 4 404 is on eyeglass 6 306；The spacer ring 3 403, eyeglass 5 305, every
Enclose 4 404 and eyeglass 6 306 be sequentially arranged in the mirror cell hole of lens barrel 402, and spacer ring 3 403, eyeglass 5 305, spacer ring four
404 and eyeglass 6 306 installed from the bottom of lens barrel 402；The pressure ring 405 is arranged on the bottom of lens barrel 402, pressure ring 405
Optical filter 307 is provided with, the optical filter 307 is fixed on pressure ring 405 using dispensing mode, the inner side of pressure ring 405 is provided with interior
Screw thread, the outside of lens barrel 402 is provided with external screw thread, and pressure ring 405 is completed to connect, so designed by internal thread and externally threaded cooperation
Purpose be easy for the dismounting of optical filter 307, conveniently reprocess；The pressure-bearing of pressure ring 405 is on eyeglass 6 306；
Assemble sequence to lens construction is divided into formal dress and anti-dress, and formal dress is that lens barrel 402 is put on assembling table top first,
Group enters eyeglass 4 304 first, eyeglass 4 304 is born against on the positioning datum 1 of lens barrel 402, then group enters eyeglass three successively
303 and eyeglass 2 302, then group enter eyeglass 1, eyeglass 1 is born against on the positioning datum 2 202 of lens barrel 402, so
After will cover trim ring 401, so far complete formal dress；Eyeglass 2 302 need to be ensured with eyeglass 1 just during Design Orientation benchmark 1
There are 0.2MM gaps during dress, can not be bearing on, in case influence eyeglass 1 is born against on the positioning datum 2 202 of lens barrel 402.
Then it is counter to be filled, first invert camera lens make camera lens load assembling by platform, make the upside of eyeglass 1 with by platform
It is bearing on, then pressing eyeglass 4 304 makes eyeglass 2 302 be bearing on eyeglass 1, then group enters spacer ring 3 403, eyeglass five successively
