Annular thin-wall parts fixture and method for processing thin-wall outer surface of parts

Abstract

The invention discloses an annular thin-wall parts fixture which comprises a cylindrical fixture support, at least three limiting blocks and at least three pressing blocks. An L-symmetrical-shaped step which is not higher than the upper end surface of the cylindrical fixture support is arranged on the outer side of the upper end surface of the cylindrical fixture support along the circumferentialcircle; an annular thin-wall parts is arranged on the step; the limiting blocks are circumferentially and uniformly distributed and fixedly arranged on the fixture support; one ends of the limiting blocks are arranged on the upper end surface of the fixture support; the side surfaces of the ends of the limiting blocks are close to the inner ring surface of the annular thin-wall parts; the pressingblocks and the limiting blocks are fixedly arranged on the fixture support at even intervals; and one ends of the pressing blocks presses the upper end surface of the annular thin-wall parts. The fixture support is used for supporting and limiting, the at least three limiting blocks are used for further limiting, and the at least three pressing blocks are used for pressing, so that the annular thin-wall parts is fixed and clamped and cannot be deformed when the thin-wall outer surface is processed, and the processing quality and the processing efficiency of the annular thin-wall parts are improved.

Description

technical field [0001] The invention belongs to the technical field of machining and clamping, and in particular relates to a fixture for an annular thin-walled part and a method for processing the thin-walled outer surface of the part. Background technique [0002] like Figure 4 and Figure 5 The ring-shaped thin-walled parts in the medium have poor rigidity due to thin wall, such as Image 6 Using B as the support and pressing plate A directly against C will generate a large pressing force. After processing, the annular thin-walled parts will deform and spring back, making it difficult to meet the technical requirements, resulting in unqualified inspection. Contents of the invention [0003] In view of this, the main purpose of the present invention is to provide a fixture for clamping annular thin-walled parts, and to provide a method for processing the thin-walled outer surface of annular thin-walled parts, which solves the problem of using traditional fixtures in th...
