A WELDING POINT CONTROL DEVICE OF WELDING TORCH FOR HYBRID WELDING HEAD

摘要

PURPOSE: A welding point control device of a welding torch for a hybrid welding head is provided to automatically change a position of a welding torch with respect to a laser head by driving a rotary motor member, thereby easily changing a pre-welding without the movement of a welding robot even in a process at a narrow space. CONSTITUTION: A welding point control device of a welding torch for a hybrid welding head comprises a rotary motor member(20) and a connecting ring(29). The rotary motor member is installed in the one side circumference of a laser head(11). The rotary motor member rotates a rotary ring(21) around the laser head by electrical signals. The connection ring is fixed in the one side circumference of a welding torch. One side of the connection ring is connected to one side of the rotary ring of the rotary motor member. The rotary motor member comprises a fixing ring(23) and a rotary ring. The fixing ring is inserted into the one side circumference of the laser head. A coil(25) excited according to control signals is embedded in the inside of the fixing ring. The rotary ring rotates around the fixing ring. Permanent magnet(27) is embedded in the rotary ring along the inner circumference at a constant interval.
