Claims

[Scope of utility model registration request]

A cart movably mounted on the machine base is biased in one direction, and a plurality of feed dogs are provided on the cart, and a stopper member that can be engaged and detached from each of the feed dogs is engaged with one of the feed dogs. The stopper member is sequentially engaged with and disengaged from each of the feed dogs in response to the operation of a spot gun that moves up and down intermittently, thereby restricting the movement of the cart in one direction. In a spot welding machine that is moved intermittently to sequentially weld multiple locations on a workpiece placed on the trolley, the welding machine is tiltable by one end of the welding machine abutting the trolley and moving in one direction. and a cam member that engages with the other end of the arm, rotates intermittently in response to the vertical movement of the spot gun, sequentially allows the arm to tilt, and returns the arm at the end of the welding work. A mechanism for automatically returning a workpiece to its original position in a spot welding machine, characterized in that the carriage is pushed in the other direction by the return action of the arm.
