Abstract

The invention discloses an anti-deformation auxiliary tool for turning a thin-wall end cover and a turning method, relates to an auxiliary tool for turning a thin-wall end cover and a turning method, and aims to solve the problems that the thinnest position of an existing unit end cover workpiece is 1.6 mm, deformation is prone to occurring in the machining process, the dimensional tolerance and form and location tolerance of a product cannot be guaranteed, the machining progress of the product is affected, and the nitriding position of the workpiece is easy to be stubble. The anti-deformation auxiliary tool comprises a clamping fixture, a pressing plate and a clamping connecting piece; and the clamping fixture is a circular plate body, an annular protrusion is machined on the outer circle face of the circular plate body, the thickness of the annular protrusion is larger than that of the circular plate body, an inner threaded hole is machined in the center of the circular plate body, the pressing plate is a circular plate with a through hole formed in the center, one end of the clamping connecting piece is clamped on the pressing plate, and the other end of the clamping connecting piece is in threaded connection with an inner threaded hole of the clamping fixture. The invention belongs to the field of turbine machining.

Description

Technical field [0001] The present invention relates to a turning thin wall end cap auxiliary tool and a turning method, and more particularly to a vehicle-shaped wall end cover anti-deformation aid and turning method. It belongs to the field of steam turbine machinery. Background technique [0002] The thinner position of the end cover of the steam turbine unit is 1.6 mm, which belongs to a typical thin wall member, and the dimensional tolerance is in 0.04 mm, and the shade tolerance is also in 0.03 mm. At the same time, its structure and its irregularities, the workpiece requires difficulties in the process of processing, the nitrid position is easy, and if the routine processing method cannot guarantee the product size tolerance and the shade tolerance, directly affect the processing progress of the product, thereby There is a need for a technical solution that guarantees the quality requirements of workpiece. Inventive content [0003] It is an object of the present inventio...
