Planet carrier assembly welding tool and welding method

Abstract

The invention discloses a planet carrier assembly welding tool which comprises a base, wherein the upper surface of the base is a horizontal plane, a three-jaw chuck is fixedly arranged below the base, a clamping jaw receding hole allowing a clamping jaw of the three-jaw chuck to vertically penetrate out is formed in the base, and a floating positioning block is arranged at the upper end of the clamping jaw; the floating positioning block is vertically arranged on a mandrel vertically arranged at the upper end of the clamping jaw in a sliding mode and located above the base, the lower surface, located on the outer side of the clamping jaw, of the floating positioning block and the upper surface of the base form a positioning clamping plane, and the upper surface, located on the outer side of the clamping jaw, of the floating positioning block forms a placing plane; the thickness of the floating positioning block located on the outer side of the clamping jaw is equal to the planet carrier assembly welding control interval, a vertical positioning pin is arranged on the base, and the height of the positioning pin is larger than the thickness of the floating positioning block located on the outer side of the clamping jaw. The middle distance of the planet carrier assembly is ensured to be qualified with the tool, so that the parallelism reaches the standards. Meanwhile, the invention further provides a planet carrier assembly welding method.

Description

technical field [0001] The invention relates to the technical field of a planetary carrier assembly, in particular to a welding tool and a welding method for a planetary carrier assembly. Background technique [0002] Planetary carrier assembly such as figure 1 As shown, it is welded by planetary carrier A and planetary carrier B. The planetary carrier A is set downward, and the planetary carrier B is set upward. The side plates arranged at intervals along the circumferential direction on the bottom plate of the planetary frame B extend into the arc-shaped groove opened on the bottom plate of the planetary frame A, and the top of the side plate is welded in the arc-shaped groove. Complete the connection. During processing, it is necessary to ensure that the distance between the bottom plate of planetary carrier A and the bottom plate of planetary carrier B is equal to the design distance and the parallelism between the lower surface of the bottom plate of planetary carrier...

AI Technical Summary

Problems solved by technology

However, in the actual welding construction, it is difficult to ensure the distance between the positioning planetary carrier A and the planetary carrier B, and it is also difficult to control the parallelism, resulting in a low pass rate of the finished welder.
