Automatic spin welding tool for circular seams of pipe fittings

Abstract

The invention belongs to the technical field of welding and specifically relates to an automatic spin welding tool for circular seams of pipe fittings. The automatic spin welding tool comprises a base. The base is provided with a variable frequency motor, a transmission case and an electric control cabinet. The variable frequency motor is arranged on one side of the base, and the transmission case and the electric control cabinet are arranged on the right side of the variable frequency motor side by side. The transmission case and the variable frequency motor are connected through a gear in an engaged manner. The electric control cabinet is electrically connected with the variable frequency motor. An output shaft of the transmission case is connected with a chuck. When the automatic spin welding tool for the circular seams of the pipe fittings is used for welding a flange and a steel pipe, the circular welding seams can be continuously formed, the number of welding connectors is reduced, and only one connector is arranged; and due to the fact that the flange and the steel pipe rotate at a constant speed, the circular welding seams formed during welding are relatively uniform and attractive. In addition, by means of the automatic spin welding tool for the circular seams of the pipe fittings, the production efficiency is greatly improved while the labor intensity of workers is reduced.

Description

Technical field [0001] The invention belongs to the technical field of welding, and in particular relates to a tool for automatic rotary welding of pipe joints. Background technique [0002] At present, the company’s welding work between flanges and steel pipes is mainly carried out by the company’s girth weld (internal) automatic welding device. During the welding process, the steel pipe needs to be rotated at a uniform speed, but most of them are simply used The motor drives the roller frame to rotate. This construction method has the following disadvantages: [0003] 1. The weld joint formed by welding due to the problem of speed has many defects such as unfusion; [0004] 2. Unstable rotation speed leads to uneven weld, which affects appearance quality; [0005] 3. Low work efficiency; [0006] 4. The labor intensity of workers who need to hoist back and forth is high. Summary of the invention [0007] The purpose of the present invention is to overcome the problems existing in th...
