某坦克炮长镜光学系统装调技术

为了解决坦克火控炮长视场稳定激光测距瞄准镜光学系统总装过程中稳像系统Z轴精度不高、校靶范围超差、装表范围超差、三轴平行性差的问题，提出炮瞄镜光学系统总装方法，通过采用光学自准直方法，将前置镜、高精度的平面反射镜工装、长焦距平行光管以及零位仪等设备调校建立瞄准轴零位基准，使三轴（瞄准轴、激光发射轴和激光接收轴）平行性的调校达标，并保证装表、校靶等有活动范围要求的光机部件的活动范围偏差合格，实现产品一次交检合格率由原来的60%提高到95%以上，产品的稳定性和可靠性得到提升，从而确保坦克火炮的首发命中率。

Assembly and adjustment technology for tank gunner-sprimary sight optical system

In order to solve the problems in the integrated assembly and adjustment process for the tank fire-control gunner field stable laser rangefinder collimator optical system, such as the low accuracy of Z axis in image stabilization system, overproof target range, overproof loading list range and different three-axis parallelism, an integrated assembly and adjustment technology of gun sight optical system was put forward. Using optical auto-collimation method, the lens, high-precision plane-parallel mirror, long-focal-length parallel light tube and zero position instrument were adjusted to establish sighting axis zero reference, and the parallelism of three axes (sighting axis，laser emission axis，laser receiving axis) was up to the standard. The error of photomechanical elements was qualified in benchmark range. The first delivery-check qualified rate was increased from the original 60% to 95%, and the stability and reliability of the products were got promoted, which ensured the first-round hitting probability.
