Problems solved by technology

The most commonly used reset method is to use positioning pins. The accuracy of the taper pin is higher than that of the direct pin, but the highest reset accuracy of the taper pin can only reach 5-6 μm, which does not meet the positioning accuracy requirements.

Abstract

The invention relates to the technical field of mechanical design, and discloses a high-precision reset mechanism and method, which are used for connecting a first structural member and a second structural member, and the two are also connected by a second installation screw; comprising an upper positioning member and a second structural member. a lower positioning member, the upper positioning member is fixed on the first structural member, and the lower positioning member is fixed on the second structural member; the upper positioning member and the lower positioning member are arranged opposite to each other, between the two A spherical positioning member is provided; the upper positioning member, the spherical positioning member and the lower positioning member are connected and positioned through positioning connecting members. The invention can reliably reset the two structural parts, and has simple structure, reliable function and high reset precision.

Description

technical field [0001] The present invention relates to the technical field of mechanical design, and more specifically relates to a high-precision reset mechanism and method. Background technique [0002] For many precision instruments, the key components are required to be disassembled (for maintenance, repair, etc.) and then reinstalled, and the installation position remains unchanged. Instruments or components with different functions have different requirements for the accuracy of reset after installation. Taking a high-precision aerial three-line array surveying and mapping camera as an example, both the focal plane component and the inertial measurement component inside the camera require a reset accuracy of 2 μm after disassembly, because the focal plane reset accuracy affects the camera principal point position error, and the inertial measurement component reset accuracy affects The eccentricity error and collimation axis error between it and the camera directly det...
