Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a rotary welding clamping apparatus for three-directional clamp welding,

The present invention relates to a rotary three-way welding jig for producing a three-way steel corner clamp product of an LNG cargo hold, and more particularly to a rotary three- In order to weld the welded part forming the welded part with each other, the worker rotates the workpiece of the welding jig device so that the welded part is positioned at the welded position of the worker without moving the user so that the welded part can be welded accurately and conveniently To a rotary type welding clamping device for directional clamp welding.

The types of welding are various, such as spot welding, arc welding, laser welding, induction welding, and brazing. The automobile industry manufactures the body by joining a number of parts made of iron-based alloy, non-ferrous alloy, etc. by various welding. In order to weld these parts, welding equipment or automatic robot welding equipment gripped by workers and parts And a welding jig for fixing the welding wire.

Welding of these parts is a technique of joining two parts to be welded. Since the part to be welded must be abutted against the part to be welded, it is necessary to move the equipment to be welded together and carry out welding, Welding was only possible at an accessible distance of the electrode.

However, in order to weld the periphery of a workpiece, such as a metal mold, which is difficult to carry and ambiguous in size, a worker must carry out welding around the workpiece, so that a wire or a hose connecting the welding rod is twisted There is a problem in that the fatigue of the worker is increased because the worker must perform the welding by breaking his or her back.

In order to solve such problems, conventionally, a "rotary type welding jig" of Korean Patent Laid-Open Publication No. 10-2012-0074001 (published on 2012.7.5) has been disclosed. Such a conventional rotary type welding jig has a plurality A main frame installed on the floor so as to be close to a welding robot for welding workpieces of a type; A turning frame installed to be rotatable in the main frame, the turning frame having a plurality of platforms; A plurality of clamping devices installed on the plurality of platforms to clamp each of the workpieces of any one of the plurality of types of workpieces; And driving means installed in the main frame and connected to the turning frame to rotate the turning frame.

In the conventional rotary type welding jig having such a configuration, since the workpiece or the welding robot can be welded by rotating the workpiece by installing the workpiece on the turning frame, the workpiece is welded and connected to the welding rod It is possible to prevent breakage of the wire or the hose and reduce the fatigue of the worker. However, since the conventional rotary type welding jig places a plurality of workpieces radially in the turning frame, only one part of each workpiece can be welded , There is a problem in that it is difficult to perform the welding around the whole circumference of the workpiece.

In addition, since only the workpieces that can be placed on the turning frame can be welded, it is difficult to perform welding on various types of workpieces.
