摘要： PURPOSE:To prevent the cleaning defect occurring in brush wear and improve the reliability of brush cleaning by applying elastic energization to a brush for cleaning the inner peripheral surface of the nozzle part of a welding torch. CONSTITUTION:This welding torch nozzle cleaning device of a consumable electrode type welding device has a brush holder 36 for holding the rotary brush 40A, lifting devices 31 32 for lifting this brush holder 36, rotating mechanisms 33, 34A, 34B, for rotating the rotary brush and an energizing mechanism 47 for elastically energizing the brush body 41 of the rotary brush 40A in a direction different from the lifting direction thereof. The rotary brush 40A receives the elastic energization toward the inner peripheral surface of the nozzle and is held locked non-displaceably at the time of non-cleaning but when the brush is inserted into the nozzle, the brush is unlocked and is made displaceable toward the inside surface of the nozzle by the elastic energization and, therefore, the cleaning defect by the wear of the brush body 41 is surely prevented.

摘要： PURPOSE:To perform girth welding on a restricted column, to release strain caused on a diaphragm to gap parts and to prevent the action of excessive stress on spacer members and clamping members, etc., by forming the gap parts on the spacer members to abut on diaphragm corner parts. CONSTITUTION:The temporarily assembled column 1 and the corner parts of the diaphragm 5 of both ends are restricted on rotary face plates 6 and 7 of a positioner 10 for welding by the clamping members 26 via the spacer members 25. Although the column 1 held on the positioner 10 for welding is subjected to girth welding, since the abutted surfaces between the spacer members 25 and the corner parts of the diaphragm 5 are made into the tapered surfaces 25a, even if welding distortion is caused on the diaphragm 5, the distortion is released along the tapered surfaces 25a. Accordingly, it is prevented that the excessive stress is acted on each member of the spacer members 25 and the clamping members 26 and the generation of deformation and damage of each part is prevented surely.

摘要： PURPOSE:To reset a work tool into an original position with extreme accuracy without generating play by providing a reset means for supplying energizing force in the direction of the recessed part of an external force detecting member coinciding with the protruding part of an original position regulating member. CONSTITUTION:When external shock acts upon a work tool, an external force detecting means 3 moves in relation to an original position regulating member 2 while opposing the energizing force of a reset means (spring) 5 to absorb the external shock. When the factor of the external shock is removed after such shock absorbing action, the recessed part 3c of the external force detecting member 3 and the protruding part 2a of the original position regulating member 2 come to coincide with each other by the energizing force of the reset means 5. At this time, there is no clearance at all between the recessed part 3c of the external force detecting member 3 and the protruding part 2a of the original position regulating member 2, nor is play generated, so that the work tool is reset into the original position with extreme accuracy.

摘要： PURPOSE:To surely carry out automatic exchange of nozzles without carrying out teaching with high accuracy by providing coil springs in the two kinds of winding directions and a rotational driving source capable of rotating these normally and reversely. CONSTITUTION:In removing the nozzles 1A and 1B from a welding torch main body 2, the coil springs 3 and 4 in the same winding direction as that of a screwed part between the nozzles and the welding torch main body are used and a welding torch is moved toward these coil springs and the nozzles 1A and 1B are fitted to the coil springs 3 and 4. At this time, the nozzles are fitted smoothly into the coil springs by slowly driving the coil springs 3 and 4 to rotate in the nozzle tightening direction by the rotational driving source 5. In addition, even if the insertion positions of the nozzles into the coil springs are deviated slightly, the deviation can be easily followed by deformation or deflection of the coil springs. When the coil springs are driven to rotate after the nossles are fitted into the coil springs in this way, the rotational driving force is transmitted to the nozzles via the coil springs and the nozzles are removed from the welding torch main body 2.

摘要： PURPOSE:A fume remover capable of creating a comfortable working environment, having a structure in which a permeable resisting part beneath a ceiling of uneven shape and a fume cxhaust port is opened between the ceiling and the permeable resisting part. CONSTITUTION:The ceiling 3 provided on the duct and guarder 2 placed between the struts I is formed into an uneven shape by means of the spoke 4. The flexble material 5 is placed along the spoke 4, and the netting 6 as a permeable resisting part is laid beneath the ceiling to form a triangled columnar continuous space. The fume exhaust port 7 is each provided in the space, and the periphery of the ceiling 3 is provided with the air jetting hole II to form an sir curtain which separates the working place from the outside. The fume generated in the compartment goes up and reaches the ceiling 3 through the netting 6. Then, the fume is trapped in the uneven portions of the ceiling 3 without convection. The fume is sucked into the duct and guarder 2 through the exhaust port 7 by means of a fan and then exhausted to the outside.
