Problems solved by technology

[0005] Before the inner surface turning process, the outer surface of the product needs to be fixed and supported to resist the cutting load and ensure the machining accuracy of the inner shape. Since the product is a blank obtained after flat spinning, the forming accuracy of the outer surface is not high and the consistency is relatively high. Poor, if the fixed support of the external surface adopts the traditional carcass positioning method, it cannot meet the fixed support requirements of product processing
[0006] The special tooling for processing hemispherica

Abstract

The invention relates to the technical field of integral spinning forming type hemispherical shell molded surface precision machining, in particular to an integral spinning hemispherical shell dot-matrix flexible fixing and supporting device, which comprises a tooling base and a dot-matrix flexible supporting mechanism; the tooling base is composed of a base upper flat plate, a base lower flat plate, a plurality of base shaping plates and a plurality of connecting rings, all the connecting rings are of circular structures, and the radiuses of the connecting rings are sequentially reduced fromtop to bottom; the dot-matrix flexible supporting mechanism comprises a plurality of flexible supporting assemblies installed on the connecting rings; and the flexible supporting assemblies all pointto the center of a hemispherical shell. An integral flexible positioning and supporting system formed by multiple sets of dot-matrix hydraulic floating supporting cylinders is matched with a pressingmechanism of an inner profile machining tooling to fixedly press an integral spinning hemispherical shell product blank onto the supporting mechanism, and the product machining precision is guaranteed; and the machining clamping efficiency and reliability of the inner profile of the whole spinning hemispherical shell product are improved.

Description

technical field [0001] The invention relates to the technical field of precise mechanical processing of the surface of a hemispherical shell formed by integral spinning, in particular to a dot-matrix flexible fixed support device for an integral spinning hemispherical shell. Background technique [0002] At present, the integral spinning-formed hemispherical shell head is widely used in pressure vessels, aerospace and other fields, and has significant advantages. Especially in the field of aerospace, the heads of medium and large-diameter hemispherical shells are usually manufactured by the method of separate forming of parts and then integral tailor welding, which has many welding seams, many intermediate processing steps, long process, low overall manufacturing efficiency, and lack of To solve a series of problems such as interchangeability, the head of medium and large diameter hemispherical shell adopts the overall manufacturing process improvement scheme of integral spi...
