Abstract

The invention discloses a welding fixture and a welding method for cylinder block parts, and belongs to the field of welding processing. The welding fixture comprises a base bearing part, a flange bearing part and a supporting plate, wherein the base bearing part comprises a first annular plate, a circular plate, and a connecting plate which are located on the same plane; the flange bearing part comprises a second annular plate; the centers of circles of the first annular plate and the circular plate coincide; the first annular plate is fixedly connected to the circular plate through the connecting plate; an arc-shaped groove which is matched with an arc-shaped convex block is formed in the circular plate; the second annular plate and the first annular plate are oppositely arranged; the second annular plate is fixedly connected to the first annular plate through the supporting plate; and an annular groove which is matched with a flange is formed in the second annular plate. The weldingfixture has fixation and supporting effects on a base and a cylinder block flange and avoids the welding deformation of the cylinder block parts.

Description

technical field [0001] The invention relates to the field of welding processing, in particular to a welding tool and a welding method for cylinder parts. Background technique [0002] The cylinder is a cylindrical metal part that guides the piston to perform linear reciprocating motion in the cylinder. The cylinder block of the cylinder is assembled from several cylinder block parts. [0003] In order to realize underwater launch, a cylinder part is currently designed. The cylinder body parts are composed of base, sleeve, flange and sealing layer. The base includes an integrally formed hemispherical cavity and a connecting seat, the flange and the hemispherical cavity are coaxially welded, the hemispherical cavity is used to form the cylinder of the cylinder, and the connecting seat and the flange are used to achieve assembly with other parts; The connecting seat is provided with a through hole communicating with the hemispherical cavity, the sleeve is welded in the throu...
