Various types of welding rotator｜Self-aligning, adjustable, anti-channeling

A welding rotator is a common electric welding auxiliary equipment, which is widely used in the welding process of various large cylinder equipment. By relying on the sliding friction between the welding workpiece and the rollers of the welding rotator, the cylinder-type welding parts are driven to rotate, and it can also be used in combination with welding manipulators, welding positioners, etc. to maintain the inner and outer circumferential seams of the butt welding parts. Welding automation of fillet welds and internal and external longitudinal seams.

Welding rotator can be divided into self-adjusting type, adjustable type, non-self-adjusting type, anti-channeling explosion-proof type, etc., all of which can be used for electric welding, grinding, and polishing, rubber lining, and assembly line of cylindrical heads. The self-adjusting rotator can be adjusted according to the size of the head.  Adjustable rotator can be adjusted according to the screw nut or screw grading adjustment, using AC and DC frequency conversion control, the angular velocity is a large number of display information.

Self-adjusting welding rotator

A self-adjusting welding rotator is a displacement machine that uses the sliding friction between the positive roller and the welding piece to push the workpiece to rotate. The welding rotator can automatically adjust the swing angle of the wheelset according to the diameter of the workpiece, and can automatically adjust the center. It is suitable for the assembly line or welding of cylindrical workpieces such as pipelines, utensils, heating furnaces, and oil storage tanks. When equipped with welding manipulators and welding robots, it can maintain the inner and outer longitudinal seams and inner and outer circumferential seams of the workpiece.

Adjustable welding rotator

The adjustable welding rotator consists of a drive wheel and a slave drive wheel. Active roller operation is driven by two motors respectively. According to the electromagnetic speed regulation motor, the speed change control board maintains the step-less speed change according to the speed regulation of the AC motor or the electromagnetic induction speed change. The angular speed of the workpiece rotation is 6-60 meters per hour, which can take into account various welding requirements such as manual welding, automatic spray welding, automatic arc welding, etc., as well as various riveting requirements of the workpiece. usefulness. The interval between the main and driven rollers can be adjusted according to the screw nut or screw grading, to consider the welding regulations of different specifications and types of workpieces.

Non-self-adjusting welding rotator

The non-self-adjusting welding rotator adjusts the distance between the rollers by moving the roller seat on the support frame.

Anti-channel welding rotator

The anti-channeling welding rotator is based on the adjustable rotator. The roller of the driven frame is made into a liftable mechanism, the photoelectric encoder is used to check the channeling angular momentum of the workpiece, and the system software control panel controls the elevator of the driven roller. The offset inspection stand is placed at one end of the workpiece, and the inspection wheel is pressed against the end surface of the workpiece. The inspection wheel can rotate with the workpiece. When the workpiece moves radially, the inspection wheel will turn to the headlight together with the workpiece. The channeling angular momentum and swaying orientation of the workpiece is input into the system software control panel for resolution. The control board will adjust the elevator stroke arrangement, elevator speed, and elevator time interval of the driven roller according to the size of the channeling angular momentum, and control the up or down according to the shaking direction.
