SWIVEL UNIT USED IN SPOT WELDING BY ROBOT ARM PREVENTING FEEDING WIRE DAMAGE

摘要

PURPOSE: A swivel unit used in spot welding by a robot arm is provided to prevent feeding wires including various electric wires and hoses from being broken by passing the feeding wires through a spring. CONSTITUTION: A swivel unit(1) used in a spot welding includes a fixing unit(2) maintained in a fixed position regardless of a rotational movement of a spot gun, a rotating unit(3), and a cable. The fixing unit has a hollow section formed at an inner portion of the fixing unit. The fixing unit(2) receives feeding wires through an input connection hole formed at one side of an outer end thereof. The fixing unit(2) includes an exhaust port for exhausting the feeding wires received through the input connection hole to an external. The rotating unit(3) has an output connection hole(32) connected to output feeding wires in order to exhaust the feeding wires to the exterior.
