Abstract

The invention discloses a turning method of a pressing ring, and relates to the technical field of machining. A pressing ring turning clamp is adopted. The turning method comprises the following operation steps that A, the clamp is mounted, wherein the pressing ring turning clamp is arranged in a taper hole part of a center hole of a lathe through a taper shank, a pull rod is made to penetrate the center hole of the lathe to stretch out of the tail end of the lathe, and an upper pressing plate and a nut are sequentially arranged on a threaded segment at the rear end of the pull rod in a penetrating manner; B, parts are mounted, wherein a pressing ring barrel blank is arranged on a pressing ring mounting portion of a locating sleeve in a sleeved manner, so that the pressing plate abuts against the tail end of the lathe, the nut on the threaded segment at the rear end of the pull rod is fastened, and the pressing ring barrel blank is tensioned on the pressing ring mounting portion of the locating sleeve; and C, the lathe is started, a turning tool is adopted for carrying out turning on the outer circle of the pressing ring barrel blank, and the pressing ring is obtained after cutting off. Compared with the prior art, the turning method can solve the problem that ellipses easily occur when inner circle turning is carried out on an existing pressing ring.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to a turning method for a pressure ring on a microscope converter. Background technique [0002] The converter is one of the important parts of the microscope, and the objective lens of the microscope is installed on the lens barrel through the converter; the pressure ring is a part of the converter, and there is a pressure ring of the converter, which is a cylindrical thin wall pieces. One of the processes of pressing ring processing is turning and cutting the outer circle of the pressing ring; the current method of turning the outer circle of the pressing ring is: the pressing ring after the inner hole is placed on the expanding sleeve with a tapered handle, and then a expanding sleeve with a tapered body is used. After the screw on the top expands the expansion sleeve and tightens the pressure ring, the outer circle of the pressure ring can be turned. This processing method h...
