Abstract

The invention discloses a rotary assembly welding tool capable of improving the welding quality of gear cases of locomotives. The rotary assembly welding tool comprises a support frame, a rotator, at least two upper case body connecting plate compressing assemblies, at least two lower case body connecting plate compressing assemblies, upper collar ring compressing assemblies and lower collar ring compressing assemblies. The support frame comprises a first support and a second support, the rotator is arranged between the first support and the second support in a rotationally connected manner and comprises a rotary plate, an upper case module and a lower case module, and the shapes and the contour sizes of the upper case module and the lower case module are matched with the shapes and the contour sizes of upper case bodies of the gear cases and gear case inner cavities of the upper case bodies of the gear cases; the upper case body connecting plate compressing assemblies are used for compressing connecting plates of the upper case bodies of the gear cases on one side of the rotary plate, the lower case body connecting plate compressing assemblies are used for compressing connecting plates of lower case bodies of the gear cases on the other side of the rotary plate, the upper collar ring compressing assemblies are used for compressing collar rings of the gear cases on two sides of the upper case module, and the lower collar ring compressing assemblies are used for compressing the collar rings of the gear cases on two sides of the lower case module. The rotary assembly welding tool has the advantages that the welding quality and the production efficiency can be improved.

Description

technical field [0001] The invention relates to a rotary welding assembly tool and a welding assembly method thereof, in particular to a rotary assembly welding tool and a welding assembly method capable of improving the welding quality of a locomotive gearbox, and belongs to the technical field of auxiliary assembly welding tooling for a locomotive gearbox. Background technique [0002] The gearbox is a thin-walled box-shaped part that protects the transmission gear. Due to the small space allocated to the gearbox, the design is determined to be a thin-plate welded structure. The gear box adopts split mode, which is composed of upper box and lower box. Such as Figure 1 to Figure 3 As shown, the upper box 1 includes an upper box body 11 and an upper box connection plate 12 welded on the bottom of the upper box body 11, and the lower box 2 includes a lower box body 21 and a lower box body 21 welded on the bottom of the lower box body. The lower box connecting plate 22 at th...
