Abstract

The invention discloses an accurate off-line shaft fixing device and an accurate off-line shaft fixing method of a wedge-shaped lens disassembly and assembly unit, and relates to an off-line shaft fixing device and an off-line shaft fixing method, aiming at solving the problem that the conventional off-line shaft fixing device and method cannot realize large-batch and high-accuracy shaft fixation. According to the device, a wedge-shaped lens optical machine assembly frame is arranged on the middle part of an optical platform, two auto-collimation pedestals are arranged on the two sides of the wedge-shaped lens optical machine assembly frame respectively, and a wedge-shaped lens substitute is fixedly arranged on the wedge-shaped lens optical machine assembly frame. The method comprises the following steps: 1, mounting the wedge-shaped lens substitute; 2, adjusting auto-collimators; 3, taking the wedge-shaped lens substitute off; 4, performing off-line mounting of the wedge-shaped lens on-line disassembly and assembly unit; 5, performing large-batch optical machine off-line assembly and check of wedge-shaped lenses; 6, performing off-line shaft fixation of the wedge-shaped lenses; 7, performing off-line shaft fixation check by an off-line assembly and check platform; 8, finishing shaft fixation check; and 9, finishing accurate off-line shaft fixation. The accurate off-line shaft fixing device and method are used for accurate off-line shaft fixation of the wedge-shaped lens disassembly and assembly unit.

Description

technical field [0001] The invention relates to a precise offline axis fixing device and method, in particular to a precise offline axis fixing device and method for a wedge-shaped lens disassembly unit. Background technique [0002] In the large-aperture optical focusing and frequency conversion system, the purpose of precise axis positioning of the lens is to achieve the coincidence of the optical axis and the mechanical axis of the system, so as to ensure that the large-aperture optical focusing and frequency conversion system is integrated into the laser inertial confinement fusion device through the mechanical interface , its optical precision can meet the design requirements of the device, avoiding complex online optical adjustments. At the same time, in order to realize the online replacement of the optical components after the large-aperture optical focusing and frequency conversion system is integrated into the laser inertial confinement nuclear fusion device, it is...
