ROTARY ARC SENSOR Russian patent published in 2021 - IPC B23K9/127 B23K9/32 

FIELD: welding.

SUBSTANCE: invention is intended for automatic welding using welding sensors to track the weld. The magnetic ring (12) is mounted on the rotating shaft (11) of the motor (1). The position encoder (13) is used to read the rotation data of the magnetic ring (12), the connecting rod (2) - to drive the welding gun in a circular motion. In the upper part of the motor (1) there is a sliding unit (3), which ensures the unhindered movement of the connecting rod (2). The swinging eccentric element (4) provides a circular movement of the lower end of the connecting rod (2) and contains a first flange (41) and a second flange (42) located with a center offset by the amount of eccentricity. The lower end of the connecting rod (2) is connected by a bearing unit to the inner wall of the second flange (42) and is provided with a connecting unit that contains a clamping element (22) with the ability to connect with a welding gun.

EFFECT: welding gun can be positioned and removed outside of the arc sensor to obtain an accurate gun path for easy maintenance and replacement.
