3 WELDING JIG APPARATUS HAVING 3-WAY CLAMP OF ROTATION TYPE

摘要

Disclosed is a rotation type welding clamping apparatus for 3-way clamp welding, in which a welding part is moved in position for welding without movement of a user when the user rotates a work stand of a welding jig device after fixing a workpeice, which includes a horizontal plate and a vertical plate as a 3-way steel corner clamp product of an LNG baggage rack and contacting surfaces of the horizontal plate and the vertical plate with each other, so that the user can accurately and conveniently weld a welded part. In order to weld the welded part at a position that the horizontal plate and the vertical plate face each other or get in contact with each other, the rotation type welding clamping apparatus fixes the horizontal plate and the vertical plate, and is rotated to make the welded part face the correct position of the user without movement of the user. The rotation type welding clamping apparatus comprises: supporters mounted at both sides to be spaced apart from each other; a rotation inducing part disposed at an upper portion of one among the supporters to induce rotation; a driving power transfer member having a rotary driving part disposed at an upper portion of the other supporter and a driving part connected with the rotary driving part by a rotating belt and disposed below the supporters; a welding stand having a horizontal support part having connection fixing portions disposed at upper portions of the both supporters and integrally fixed at centers of both end portions to be connected with the rotation inducing part and the rotary driving part, a first vertical support part extending upwardly from one side with respect to the center of a rear end of the horizontal support part, and a second vertical support part extending upwardly from the other side.
