MOBILE TYPE FILLET WELDING MACHINE

摘要

PURPOSE:To execute welding automatically and continuously without leaving it unfinished by providing a mechanism which is capable of a linear reciprocating motion along a fillet welding line extending over the range between both switches provided on front and rear end parts of a truck, and making this mechanism hold a welding torch. CONSTITUTION:A link mechanism for converting a driven rotary motion of a driving motor 32 to a linear motion running along a fillet welding line (a) extending over a range between both switches LS1, LS2 is constituted. A wire cable part 42 provided with an arc welding torch 6 on the tip is fixed to a swing arm in this mechanism through clamp fittings, and it is constituted so that the welding torch 6 can execute a linear movement along the fillet welding line (a) by a link motion of the link mechanism. Also, this machine is constituted so that an aimed angle of the welding torch 6 can be set and changed by adjusting a position in the circular arc direction of a slider 22.
