Turnover mechanism for automatic welding of welding seams of cylinder

Abstract

The invention relates to a turnover mechanism for automatic welding of welding seams of a cylinder. The turnover mechanism comprises rollers, a frequency converter, a base table and a motor, wherein the rollers are divided into two groups; each group comprises a fixed roller and an adjustable roller; the two groups of rollers are respectively arranged at two ends of the welded cylinder in the length direction; the fixed rollers are fixed on the base table on the right side of the welded cylinder; the adjustable rollers are movably fixed on the base table on the left side of the welded cylinder by adjustable roller positioning pins; a layer rubber wraps each roller along a peripheral surface thereof; the length distance between the two groups of rollers is adjustable and can be adjusted according to the length of the cylinder to be welded; the fixed rollers are connected with the motor and serve as driving wheels; the adjustable rollers serve as driven wheels; the motor is connected with the frequency converter; the rollers rotate to drive the cylinder to rotate; and the revolving speed is adjustable in a frequency conversion manner according to welding needs. The turnover mechanism can be used for welding cylinders with different diameters; and automatic overturning of the cylinder can be realized, welded peripheral welding seams are uniform and attractive and do not have defects, time and labor are saved, and therefore, welding efficiency and welding quality are improved.

Description

[0001] (1) Technical field [0002] The invention relates to a turning mechanism for automatic welding of cylindrical seams, which belongs to the field of mechanical processing. [0003] (2) Background technology [0004] Medium and large cylinders generally have two or more sections, so there is a situation of circumferential butt joints. The traditional butt welding of cylinders is welded while rolling on the welding platform or the ground. The disadvantages are: 1. Low welding efficiency; 2. Due to the continuous change of the welding position, the difficulty of manual operation is increased, and the welding is manual, resulting in unstable weld quality and unsightly appearance; 3. The welding site occupies a large area. Cause production cost to remain high, especially bring a lot of inconvenience to batch production. [0005] (3) Contents of the invention [0006] In order to overcome the above-mentioned defects, the present invention provides a turning mechanism for auto...
