20120031880 | ELECTRODE UNIT OF SPOT WELDING MACHINE - An electrode unit of a spot welding machine in which a recessed fitting portion having a circular shape in section is formed in a surface of a projecting portion of an electrode holder. A first groove is formed in an inner peripheral surface of the recessed fitting portion. A cooling water passage continuous to the recessed fitting portion is formed in the electrode holder. A columnar fitting portion is formed in a base end of the abutting portion of the electrode. A second groove is formed in an outer peripheral surface of the fitting portion. The fitting portion is inserted in the recessed fitting portion. An O ring is fitted in the first groove and the second groove. Then the electrode is attached to the projecting portion. A cooling water circulated in the cooling water passage cools down the electrode and the projecting portion. | 02-09-2012 |
20110042406 | MAGAZINE FOR SPOT WELDING CHIP - A magazine for spot welding electrodes that stores mini chips and can feed the mini chips one by one. A mini chip storage portion and a cap chip storage portion slidably aligning and storing a plurality of mini chips and a plurality of cap chips are formed such that the mini chip storage portion and cap chip storage portion communicate with each other at one of their ends, where they open to the outside to serve as a supply port. When an arm is inserted into the supply port, a cap chip is mounted to the arm, as well as the cap chip presses the mini chip so that the mini chip is also mounted to the chip base. When the mounting operation is complete, a push-out member pushes the mini chips and cap chips so that the mini chips and cap chips are automatically fed to the supply port. | 02-24-2011 |
20100147806 | ELECTRODE TIP MAGAZINE FOR SPOT WELDER - An electrode tip magazine for a spot welder that does not interfere with the welding gun is provided. The magazine includes a magazine body formed with a storage part slidably aligning and storing a plurality of electrode tips therein, one end of this storage part serving as an externally opened supply port, a push-out member disposed to be freely slidable between both ends inside the storage part, a pulley disposed at a position adjacent to the supply port of the magazine body, a spiral spring disposed at a position at the other end of the storage part of the magazine body, and a wire connecting a distal end of the spiral spring and the push-out member with an intermediate portion thereof being wound around the pulley so as to always pull the push-out member toward the supply port by a biasing force of the spiral spring. | 06-17-2010 |
