Abstract

The invention is applicable to the field of impeller laser welding and discloses an impeller blade and impeller upper plate laser welding jig, an impeller blade and impeller upper plate clamping method with the jig and an impeller blade and impeller upper plate laser welding method through the clamping method. The impeller blade and impeller upper plate laser welding jig comprises a base assembly, a support assembly mounted on the base assembly for placing and positioning an impeller blade and an impeller upper plate, a pressing plate assembly arranged above the support assembly for pressing the impeller blade and the impeller upper plate to the support assembly, a first telescoping assembly mounted on the base assembly for pressing the pressing plate assembly in the axial direction of the base assembly, a plurality of peripheral pressing structures mounted on the base assembly, and a plurality of lateral positioning structures mounted on the base assembly. The impeller blade and impeller upper plate laser welding jig, the impeller blade and impeller upper plate clamping method with the jig and the impeller blade and impeller upper plate laser welding method through the clamping method solve the technical problems of poor versatility, clamping difficulty and low clamping efficiency, clamping positioning reliability and automation degree of existing impeller laser welding jigs.

Description

technical field [0001] The invention belongs to the technical field of impeller laser welding, and in particular relates to a fixture for laser welding of an impeller blade and an impeller upper plate, a clamping method for clamping an impeller blade and an impeller upper plate by using the clamp, and a clamping method for clamping an impeller blade and an impeller upper plate. Plate laser welding method. Background technique [0002] The impeller is an important part of the pump, and its size and precision directly affect the mechanical properties, working efficiency and service life of the pump. There are two main structural forms of impellers: open impeller and closed impeller. Due to its high efficiency, the closed impeller is widely used in centrifugal pumps with high lift and high efficiency. There are two kinds of blades of centrifugal pump impellers: cylindrical and space twisted. The use of space twisted blades for centrifugal pump impellers can not only reduce th...
