PROBLEM TO BE SOLVED: To perform the posture control of high degree of freedom and the position control of high accuracy by assembling a robot arm ensuring the rigidity by reducing the length of each arm and forming a hinge consisting of rotary shafts to a moving head in straight motion. SOLUTION: A robot arm having a hinge consisting of three rotary shafts is assembled to orthogonal straight moving shafts of XYZ modeled by a machine tool, and the adjacent rotary shafts of the robot arm are orthogonal to each other. Flexible posture control can be performed at an arm tip part thereby, the rigidity and the positional accuracy can be ensured by suppressing each arm joined with the joint to the necessary and sufficient length, and high function can be realized by mounting a semi-conductor welding unit DL, an auxiliary tool T and various kinds of sensors S on a tip of the robot arm.

PROBLEM TO BE SOLVED: To provide a jig for welding in both use of butt welding and lap welding. SOLUTION: The opposite sides of a fixed table 13 and a movable table 15 are provided with positioning stoppers S1 and S2 in a pair of members 10 and 11 to be welded. The outsides of the fixed table and the movable table on the opposite sides of the positioning stoppers are provided with a first pressing means P1 and a second pressing means P2 of pressing each member to be welded on each positioning stopper. One side part of the fixed table and the movable table is each provided with a standard plate SP of receiving the side edge of each member to be welded. The sides opposite to the standard plates in the fixed table and the movable table are provided with a third pressing means P3 and a fourth pressing means P4 of pressing each member to be welded to each standard plate. The opposite sides of the fixed table and the movable table are provided with a first clamping means KB and a second clamping means KB of independently clamping the butted vicinities of a pair of the members to be welded.

PROBLEM TO BE SOLVED: To provide a novel trochoid processing method for processing a pocket of an optional shape by making one of a circular arc match with the contour of a processing shape, and making the other match with the extent of a shaving-off area when processing while changing the size of the circular arc of a trochoid. SOLUTION: In this high speed pocket processing method, processes a pocket of an optional shape is processed by making one of the circular arc F1 match with the contour La of the processing shape and the other match with the extent S of the shaving-off area when processing while changing the size of the circular arc F1 of the trochoid of an end mill tool EM.

Abstract:
PROBLEM TO BE SOLVED: To cope with a line tact of a production line even if getting faster when scraps generated during laser machining are removed and to simplify the tip of a robot arm to realize light weight.SOLUTION: In a laser machining head 3 where an electromagnet 7 is arranged near a laser radiation nozzle 5, and a magnetizing surface 7a is positioned near the peripheral portion of the tip of the laser radiation nozzle 5, a surrounding member B of a scrap collecting portion 15 covers the circumference of the laser radiation nozzle 5 and that of the electromagnet 7 such that the scrap collecting portion 15 can slide around a shaft member 21 by activation of a cylinder unit 14. When machining is performed by the laser radiation nozzle 5, the cylinder unit 14 is activated by receding to be evacuated to a position where the scrap collecting portion 15 does not inhibit magnetizing of scraps W1 by the electromagnet 7, and when the scraps W1 are received at the scrap collecting portion 15, the cylinder unit 14 is activated to extend so that an original position is restored.
