Friction Welding Structure of Balance Ring and Its Processing Die

Abstract

Provided are a friction welding structure of a balancing ring, and a machining die thereof. The friction welding structure comprises an upper ring body and a lower ring body on the lower side of the upper ring body. The middle position where the upper ring body and the lower ring body join is provided with solution cavities. The upper ring body is clamped on the lower ring body. The gaps between the upper ring body and the lower ring body form the solution cavities. The upper ring body comprises an upper ring cover, and an outer side wall and an inner side wall fixed on two side ends of the upper top cover. An upper solution cavity is formed between the outer side wall and the inner side wall. The lower ring body comprises a base, and an outer melting wall fixed on the outer side of the base, and an inner melting wall fixed on the inner side of the base. The outer melting wall, the inner melting wall, and the upper surface of the base form a lower solution cavity. An outer clamping groove is arranged between the outer melting wall and the upper surface of the base. An inner clamping groove is arranged between the inner melting wall and the upper surface of the base. The ends of the outer side wall and the inner side wall are respectively inserted in the outer clamping groove and the inner clamping groove. The upper solution cavity and the lower solution cavity are jointed and communicated to form the solution cavity. The friction welding structure at least has effect of simple structure, easy processing, good sealing effect, good anti-vibration property, and no noise.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a friction welding structure of a balance ring and a processing mold thereof, which are used to prevent or reduce vibration or eccentricity when a drum in a washing machine rotates. Background technique [0002] In the prior art, application name: washing machine balance ring, application number: 97232333.3, application date: 1997-12-22, the application relates to a washing machine balance ring, which includes a ring body, which is characterized in that the inside of the ring body The ring is provided with an upwardly protruding annular rib. Solve the problem that the clothes enter the gap between the inner tub and the outer tub to prevent the clothes from being thrown out. This application is an early design of the balance ring, and the balance performance is still in its infancy, and the balance effect cannot be realized yet. [0003] Application name: balance ring device of d...

AI Technical Summary

Problems solved by technology

In this application, because of its complex structure, it is not easy to manufacture, and the vibrating liquid flows out from the installation position of the stopper during use, so it cannot be used for a long time

[0007] The above patent applications are all different due to their invention objectives and technical problems to be solved, so their technical solutions include differences in structure and method, and they cannot be simply combined for this patent application, otherwise it will lead to more complicated structural design. , or cannot be implemented, etc.
