Problems solved by technology
However, due to the deformation of the balance ring itself and the inaccurate alignment of the upper and lower balance rings during welding, the rejection rate of the balance ring components after welding is high, and water leakage often occurs before the service life is reached.

Embodiment Construction
[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0033] like figure 1 , 2 , 3, 4, 5, 6, 7, and 8, a balance ring welding device includes a base 7 and an upper seat 3 located above the base, and the base 7 and the upper seat 3 are fixed by a fixing rod 5, and the A lifting table 4 that can move up and down is arranged between the base and the upper seat. A lower mold 6 matching the lower balancing ring is fixed on the upper surface of the base 7. An upper mold 16 matching the upper balancing ring is fixed on the lower surface of the lifting platform 4. The upper mold The upper slide is provided with an upper positioning pin that can be inserted into the positioning hole on the upper balancing ring, and the upper positioning pin is fixed on an upper cylinder 15, such as Figure 8 As shown, the lower mold 6 is slid up and provided with a lower positioning pin that can be inserted int...

The invention relates to a balance ring melting apparatus and a method thereof. The apparatus comprises a pedestal and an upper seat positioned over the pedestal, a lifting platform which can move up and down is arranged between the pedestal and the upper seat, the upper surface of the pedestal is fixed with a lower die matched with a lower balance ring, the lower surface of the lifting platform is fixed with an upper die matched with an upper balance ring, a transverse sliding rail is arranged below the upper seat, the transverse sliding rail is provided with a heating plate seat, the heating plate seat can move up and down and is fixed with heating plates, and the heating plates can transversely move into or out of a space between the pedestal and the lifting platform. The upper balance ring and the lower balance ring are aligned in advance, upper and lower heating plates are respectively moved in or moved out to respectively heat the upper and lower balance rings, the upper and lower balance rings only vertically move up and down and cannot move transversely in the whole process, the upper and lower balance rings are accurately aligned during melting, the melting defective index is low, and the production efficiency is high.
Description
technical field [0001] The invention relates to a device and method for installing a balance ring on a washing machine. Background technique [0002] The balance ring of the washing machine is an essential balance part of the pulsator fully automatic washing machine. There is an appropriate amount of salt water sealed inside, which can prevent the outer tub from hitting the box due to the heavy weight of the clothes during the washing and drying process of the washing machine. In order to prevent the balance ring from leaking within the service life, the balance ring components must meet good sealing performance. Therefore, existing washing machines generally adopt the method of welding the upper and lower balance rings together to achieve the sealing effect. However, due to the deformation of the balance ring itself and the inaccurate alignment of the upper and lower balance rings during welding, the rejection rate of the balance ring components after welding is high, and...
