Problems solved by technology
With the increase of the turning shaft hole, the coaxiality is not easy to guarantee, and at the same time, the horizontal working condition has higher requirements on the coaxiality of the turning shaft
[0004] The usual processing method is to process the trunnion holes of the middle block, and then combine them with the side blocks to form a surface array. However, after the middle block is equipped with side blocks and devices, the bending deformation destroys the coaxial accuracy of the turning axis, and the side blocks are turned over in horizontal conditions. Difficult to even implement the flip function
Conventional processing technology cannot guarantee the coaxiality accuracy of the shaft system, and cannot realize the function of turning over the horizontal working condition

The invention relates to a large area array horizontal turning shaft system high-coaxial-precision machining process. According to the process, stress conditions of a middle area array, a left area array and a right area array are calculated through simulation analysis, when a rotating shaft hole of the middle area array is machined, the stress condition of the middle area array is loaded throughreplacing of counterweight lead blocks, the stress condition during machining is consistent with the stress condition during the horizontal working condition, the machining precision is guaranteed, when the left area array and the right area array are installed, the stress conditions of the left area array and the right area array are also loaded through replacing of counterweight lead blocks, thestress condition during installation is consistent with the stress condition of the horizontal working condition, and the installation precision is guaranteed. The process has the beneficial effectsthat the machining precision of the rotating shaft hole is high, and the installation precision is high, so that the coaxial precision of a whole large area array is guaranteed.
Description
technical field [0001] The invention relates to the technical field of antenna array processing, in particular to a high-coaxial precision machining process for a large-scale array horizontally flipped axis system. Background technique [0002] A large-scale antenna array is composed of three left, middle and right blocks. The blocks are connected by flip lugs. There are four sets of flip lugs on the left and right. In the horizontal working condition, the folding (90°) and unfolding functions of the side blocks are realized by flipping the oil cylinder. The turning shaft hole on the middle block is integrally processed together with the middle block, and the turning shaft hole on the side block is processed first in parts, and then welded when the area array is assembled. [0003] The existing area array generally has two sets of flip lugs on the left and right, and realizes the flip function in the vertical working condition. The area array has four sets of flip lugs, wit...
