Abstract
The invention relates to a longitudinal adjusting and auxiliary welding line alignment device for a welding gun of a special circumferential welding machine for an automotive transmission shaft. A welding area is far away from an operating area, and the longitudinal position of the welding gun needs to be adjusted in a long distance, so that a gear rack mechanism is used for wide-range longitudinal adjustment, the transverse length of a hand wheel shaft is increased, and operation is facilitated for operators. Besides, laser spots are used for assisting in aligning positions of welding lines. When the welding gun is longitudinally adjusted, a laser transmitter synchronously moves along with the welding gun, and the working position of the welding gun is positioned by red laser spots emitted by the laser transmitter, so that the adjusting position of the welding gun is conveniently determined by the operators. The device can be applied to longitudinal adjustment and welding line alignment for the welding gun of the special welding machine, and the welding gun of the special welding machine is adjusted more simply and conveniently, so that production efficiency can be improved, and labor intensity is reduced.
