摘要： PROBLEM TO BE SOLVED: To provide a friction stir welding apparatus capable of performing flexible response irrespective of the size and the shape of a work to be welded. SOLUTION: A vehicle body 34 travels along a welding line 29 of a work 23 while a tool holding part 31 to hold a welding tool 24 is rotated and embedded in the work 23. Two members 21 and 22 to be welded are welded thereby. The vehicle body 34 travels above or below the work 23. A friction stir welding apparatus 20 need not support the tool holding part 31, a rotary driving means 32 and a displacement means 33 outwardly in the horizontal direction of the work 23. Thus, friction stir welding can be performed irrespective of the size and the shape of the work 23. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide an apparatus for friction stirring joining, which has a simplified configuration, excellent workability, and compactness. SOLUTION: The apparatus for friction stirring joining has a base frame 23 fixed to a predetermined position, and a tool holder 29 for holding a joining tool 21, which is arranged on the base frame 23 so as to rotate on a predetermined reference axis L1 and also move along the reference axis L1. Because a workpiece 22 to be joined is moved to be positioned with respect to the base frame 23, it is unnecessary to move the base frame 23 for positioning with respect to the workpiece 22. As a result, the configuration is compact and simplified without requiring an arm for moving the base frame 23. Further, since the base frame 23 is fixed, a teaching operation for adjusting the movement position of the base frame 23 becomes unnecessary and a work for changing the joining tool 21 is facilitated.

摘要： PROBLEM TO BE SOLVED: To shorten the measuring time by calculating the safe near position to a grinding wheel surface on the basis of the stored data related to the dimension of a workpiece, advancing the grinding surface of the workpiece to this position, and then determining the positional relation between the grinding surface and the grinding wheel surface to determine the grinding route. SOLUTION: A robot controller 3 determines a proper distance L such that a workpiece 6 never collides with a grinding wheel surface, and moves the workpiece 6 to this set position at a relatively high speed. The workpiece 6 is slowly moved horizontally toward a grinding wheel 11, and when the load of a motor for rotating a grinding wheel 11 is changed and exceeds a threshold because the grinding surface of the workpiece 6 is brought into contact with the grinding wheel 11 and slightly ground, the moving distance at that time is measured and stored. The substantial plane for moving a grinding surface 61, excluding casting burr is certified by use of each measured value.

摘要： PROBLEM TO BE SOLVED: To enable application to a machine tool by mounting at least two holding claws on a four-point contact type parallel two-finger hand to press a work through the elastic material to hold the work with sufficient holding power. SOLUTION: A leaf spring 4 is fixed to the sides opposite to each other at a tip of a first finger 2 and a second finger 3. The leaf spring 4 is developed perpendicular to the axial direction of the finger and the moving direction of the finger, and a holding claw 5 having an inwardly sharp edge is fitted to the tip of the leaf spring 4. The second finger 3 has a rotary shaft 6 in the direction perpendicular to the plane on which the holding claw 5 is arranged, and the leaf spring 4 is oscillated in the plane. When two fingers 2, 3 are translated, four holding claws 5 arranged on the plane are abutted on each side of a work 10, and the work 10 is held by the edge of the claw tips. When two holding claws 5 of either finger are unevenly abutted on the side of the work 10, the rotational moment is generated around the rotary shaft 6, and the finger is rotated around the rotary shaft 6.

摘要： PROBLEM TO BE SOLVED: To prevent grinding crack and prevent a grinding wheel from being abraded partially by shifting the grinding wheel parallel to the surface of a work without any cutting feed after cutting a part of the work by a prescribed quantity so as to grind it by a grinding wheel, and repeatedly grinding it with the new surface of the grinding wheel brought in contact with the surface of the work. SOLUTION: A material 1 to be ground may be a hard and fragile high alloyed cast iron such as high chrome cast iron. After finishing the notch of a prescribed quantity by a grinding wheel 3, the grinding surface which is once formed is ground by reciprocating the grinding wheel 3 without any cutting feed this time. For example, when a work material of 30 mm width is ground by a grinding wheel of the 50 mm width, the work is finish ground by being shifted from the first work face to (a), (b), (c), and (d) by 6 mm at each time. As a result, the whole of the grinding wheel is acted with the work material 1 by one and half grinding so as to prevent the surface of the grinding wheel from being partially abraded. The whole of the material surface is slowly cooled so that a tensile stress remained on the surface layer is reduced so as to reduce the grinding crack.

摘要： PROBLEM TO BE SOLVED: To provide a spot welding system that prevents lateral runout of a welding tool caused by rotation in the case of spot FSW by accessing from one surface. SOLUTION: The spot welding system 10 is composed of an articulated robot 11, an FSW head 12 to be attached to the tip end of the robot arm, a base 13 for holding a workpiece W horizontally, and a controller 14. On the FSW head 12, there are mounted a welding tool 15 and a fixing device 16. The fixing device is equipped with a cylindrical pressurizing member 19 and a spring 18. The pressurizing member 19 is pressed against the surface of the workpiece W by the spring 18 at the time of welding, thereby temporarily fixing the welding tool 15 on the workpiece W. Thus, the lateral runout due to rotary reaction of the welding tool 15 is prevented from occurring. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To provide a friction stir welding apparatus which can flexibly cope with the size and shape of an object to be welded. SOLUTION: A car body 34 moves along the welding line 29 of the object 23 to be welded in the state that a welding tool 24 is plunged into the object 23 by turning a tool holding portion 31 holding the welding tool 24. By this operation, two members 21, 22 to be joined are welded. The car body 34 moves above or below the object 23. As a result, the friction stir welding apparatus 20 does not need to hold the tool holding portion 31, a rotationally driving means 32, and a translationally driving means 33 at the positions outside the object 23 in the horizontal direction. Therefore, the friction stir welding operation can be carried out irrespective of the size and shape of the object 23. COPYRIGHT: (C)2007,JPO&INPIT
