Automatic eccentric rotary butt welding adjustment device for round rods of different sizes

Abstract

The invention provides an automatic eccentric rotary butt welding adjustment device for round rods of different sizes, including: a chassis assembly, a power assembly, a clamping and aligning assembly, a gear shift assembly, an automatic welding assembly and an indicating assembly, which can realize different radii The round bars rotate eccentrically synchronously, the clamping and alignment of the large round bar and the small round bar do not interfere with each other and maintain self-locking, and the function of precise and adjustable welding eccentricity is of great significance for the high-quality completion of eccentric butt welding of round bars with different radii; At the same time, the set indicator component records the eccentric distance of welding in real time, which is used to realize the repeated positioning of the round rod butt joint process; the invention has novel structure and simple operation, and is equipped with two modes of manual welding and automatic welding. The butt welding position is determined by the automatic centering of the round rod, which better realizes the automatic eccentric butt welding of different sizes of round rods, simplifies the process flow of round rod eccentricity adjustment, saves production costs, and improves the production quality and efficiency of eccentric round rod butt welding.

Description

technical field [0001] The invention relates to the technical field of butt welding automatic adjustment devices, in particular to an automatic eccentric rotation butt welding adjustment device for round bars of different sizes. Background technique [0002] In actual industrial production, it is often necessary to perform off-axis butt welding of round bar-shaped parts with different radii. The eccentric butt welding seam of the common round bar-shaped parts is a circular seam, and the welding part is prone to offset when the welding part is positioned during the welding process, resulting in a large dimensional error of the welded component. In order to obtain excellent butt weld quality and accurate welded component size, it is often necessary to use specific fixtures or measure the butt position of the round bar-shaped parts before formal welding, and then pre-fix by spot welding. However, due to the complicated operation process such as position adjustment and clamping...

AI Technical Summary

Problems solved by technology

However, due to the complicated operation process such as position adjustment and clamping of the butt joint during the spot welding operation, the error of the eccentric distance of the two parts to be joined is relatively large, which needs to be corrected after welding, which makes the whole process complicated and the error of the welded components obtained is large , seriously affecting the production cost and production efficiency
