Abstract
The invention discloses a machining method for threaded holes in a fixed disc. A fixed-disc turning clamp is used. Parts are arranged, i.e., a spherical shell of the fixed disc is placed in a counter bore of a fixed-disc locating block, so that a locating pin extends into a blank hole of one threaded hole, and the axis of the threaded hole to be machined coincides with the axis of a barrel portion; and then a hand wheel is tightened so as to make a pulling rod pull a supporting sleeve backwards, and thus two fixed-disc pressing plates are in compression connection with a locating surface of the fixed disc and the fixed disc is fixed on the fixed-disc locating block. A lathe is started, and a turning tool is adopted to machine one threaded hole in the spherical shell of the fixed disc. The hand wheel is loosened, and the fixed disc with the three machined threaded holes is taken down. Compared with the prior art, the machining method is advantageous in that the problems that threaded holes in a spherical shell of a fixed disc are difficult to machine and clamping and producing efficiency is low at present can be solved.
