Automatic eccentric rotating butt welding adjusting device for round bars of different sizes

Abstract

The invention provides an automatic eccentric rotary butt welding adjusting device for round bars with different sizes. The device comprises a chassis assembly, a power assembly, a clamping and aligning assembly, a gear shifting assembly, an automatic welding assembly and an indicating assembly, and can realize synchronous eccentric rotation of the round bars with different radiuses, clamping and aligning of the large round bar and the small round bar are not interfered with each other and keep self-locking, the function that the welding eccentric distance is accurate and adjustable is achieved, and great significance is achieved for high-quality eccentric butt welding of the round bars with different radiuses; meanwhile, the arranged indicating assembly records the welding eccentric distance in real time and is used for achieving repeated positioning in the round bar butt joint process; and the device is novel in structure and easy to operate, two modes of manual welding and automatic welding are set, the butt welding position is determined in a large round bar aligning and small round bar automatic centering mode, automatic eccentric butt welding of the round bars of different sizes is better achieved, the technological process of round bar eccentric adjustment is simplified, the production cost is reduced, and the butt welding production quality and efficiency of the eccentric round bars are improved.

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
