Description

[0001] Welding Jig Appratus for Water Tank [0002]

The present invention relates to a jig device for welding a hot water tank, and more particularly, to a jig device for welding a hot water tank of a water purifier manufactured by welding two bodies to a cylindrical water tank, To a welding jig device.

Generally, a water purifier is mainly used as a cold / warm water purifier capable of selectively supplying cold water and warm water as well as providing water by purifying water.

The inside of the cold / warm water purifier is equipped with a hot water tank for warming the water and storing the heated water.

The hot water tank must be made in a volume having a closed space for supplying raw water and heated by a heater. In order to increase the volume while reducing the installation area, the hot water tank is mainly made of a cylindrical body.

The hot water tank is formed into a cylindrical shape by welding two bodies. The two bodies divided for manufacturing the hot water tank are each formed so as to have a rim protruding outwardly on the end side connected by press working or the like.

The divided two bodies are welded in a state where the rims whose ends are projected to the outer periphery are in contact with each other, and are formed into a cylindrical hot water tank.

As described above, in order to manufacture a cylindrical hot water tank, the two divided bodies must be welded with their rims aligned exactly, so that the connection portion can be completely sealed.

However, since there is no device that can fix the two bodies that are divided at the connection part exactly by matching the edges at the time of making the hot water tank, the worker directly welds the two bodies so that the welding operation time is long The production cost is lowered and the manufacturing cost is increased, and there is a problem that the defective rate of the hot water tank is increased due to leakage of water from the connecting portion due to welding defect.

In addition, the speed and accuracy of the welding work vary greatly depending on the skill of the operator. In the case of unskilled workers, welding fault incidents occur very frequently, and the production speed is greatly lowered due to the difficulty of welding work.
