Description
The present invention relates to a conveyance structure of a welding apparatus.
In general, in the industrial field to produce a variety of products by combining two or more steel materials, the welding method is mainly used to combine the steel materials. Welding is a method of joining other steel materials by melting a base material or a separate molten member at a connection part of a base material, and since the connection member is not required, the structure can be simple and lightweight, and is widely used because of its high durability.
The welding involves arc welding using melt heat generated by arc discharge, gas welding melted using oxygen and acetylene mixed gas, and electron beam welding using electron energy holding energy as a welding heat source by forming a high speed electron beam in vacuum. For example, laser beam welding for amplifying and matching light in phase with a single wavelength, and friction welding using frictional heat generated from a contact surface by relatively rotating abutment against a base metal.
Recently, an automatic welding device that automatically improves the operator's convenience by using the welding torch automatically moves along the welding line and performs the welding conveniently, in which the welding device moves along the rail.
However, in the related art, since the shape of the horizontal rail installed on the member placed flat on the ground and the vertical rail installed on the member placed perpendicular to the ground are partially different, it is impossible to use the horizontal rail and the vertical rail with one welding device. There is a problem in that a separate welding device is provided for the rail.
The present invention was created to solve the problems of the prior art as described above, an object of the present invention is to provide a horizontal unit and a drive unit to replace or rotate the rack gear engaged with the rail to utilize both the vertical rail, horizontal welding And a conveying structure of the welding device which enables the vertical welding to be performed by one welding device.
The conveying structure of the welding device according to an embodiment of the present invention, the welding device for performing welding; A rail which is installed on a member to be welded and guides the transfer of the welding apparatus, and a rack having a rack formed thereon in the upper or side direction along the conveying direction of the welding apparatus; And a driving part provided at a lower portion of the welding device and engaged with the rail to rotate and transport the welding device, wherein the driving part comprises: a rack gear that is engaged with the rack and rotates; It characterized in that it comprises a rack gear changing unit for changing the direction of the gear teeth of the rack gear by replacing or rotating the rack gear.
The conveying structure of the welding apparatus according to the present invention is a rack gear of a drive unit engaged with a rack of a vertical rail is rotated or replaced so as to be engaged with a rack of a horizontal rail, if necessary, thereby using a horizontal rail and a vertical rail. Various welding is possible by the welding apparatus, and the efficiency of a welding operation can be improved.
