摘要： PURPOSE: To restore the attitude of a robot precisely by installing an adjusting rod on a jig body so that the length is adjustable and the length adjusted can be fixed, and adjusting the robot shaft in dislocation easily and accurately. CONSTITUTION: By turning a lock nut, a jig body 11 and an adjusting rod 12 are rotated relatively in accordance with the dimensions of an upper arm 5 when it is in the reference attitude, and thereby the length L of a jig 10 for deciding the origin mechanically is adjusted in advance. Then the jig 10 is pinched by a ball screw nut 1 and a housing 7 as located between the movable part and fixed part of a robot 9, and the ball screw shaft 2 is rotated by a motor 4 to move the nut 1 in the axial direction of the shaft 2, and the housing 7 and nut 1 are abutted with the two ends of the jig 10. By the abutting, shaft dislocation of the robot 9 can be adjusted accurately, and the upper arm 5 can be restituted to the reference attitude precisely.

摘要： PURPOSE:To economize energy by cutting off or reducing a motor current, simultaneously with the operation of a brake through the cutting-off of the current-currying to the brake, in an input waiting or time lapse waiting state. CONSTITUTION:The teaching information inputted from a programming unit 4 is inputted into a control part 13 through a play-back console 3, and the contents which is previously taught is outputted into a servoamplifier 10, and a motor 5 is driven. Further, brake is released by putting a brake device 8 into electric conduction through a brake circuit 12, and the brake is operated when the electric conduction is cut off. In this case, in the control part 13, the stop time point of a robot body and the period (stop period) up to the shift starting time point succeeding the stop time point are detected successively on the basis of the teaching information, and when the stop period is detected, the electric conduction for the brake device 8 is cut off, and at the same time, the motor electric current is reduced.

摘要： PROBLEM TO BE SOLVED: To provide a motor with a compact, lightweight reduction gear at low cost. SOLUTION: A high frequency power supply 31L on the low frequency side is put in action, and a gear P is induction-heated by a low frequency side heating coil 30L to heat the root part surface of a tooth to high temperature as shown by the void in a right upper figure (1). A high frequency power supply 31H on the high frequency side is actuated, and the gear P is induction-heated by a high frequency side heating coil 30H. As shown by the void in a figure (2), only the surface is heated to high temperature on the whole from the root part to the tip excluding the center part of the tooth, and then water is jetted to the surface of the gear P in a red heat state by a water jetting device 36 for rapid cooling. The surface is thereby quenched so as to obtain quenching along tooth form down to the root as shown by the void in the figure (2). The gear thus reinforced is used to constitute reduction mechanism. Since the gear strong in both flexure and wear can be obtained by two frequency quenching, miniaturization and weight reduction can be obtained.

摘要： PURPOSE:To remove only a burr part accurately without leaving an unremoved part of a burr or causing excessive removal of the burr when a non-burr part is copied by a copying part and the burr is removed by a tool part by arranging the copying part and the tool part coaxially almost in the same diameter. CONSTITUTION:A deburring tool part 1 is fixed to a shaft 8 of a driving motor 11 by a bolt 6, and a copying part 2 is fixed by an unheaded screw 7 to a shaft 3 supported with a housing 5 through a bearing 4. The housing 5 is fixed to a force sensor 10, and force applied to the copying part 2 is detected by the sensor 10, and the detecting signal is inputted to a robot controller. Copying operation of a robot is carried out while feeding back the force applied to the copying part 2, and at play back time, the tool part 1 is made to enter in the perpendicualr direction to a burr part of a work, and the copying part 2 is run along a non-burr part of the work, and a burr is removed by the tool part 1 while keeping the force applied to the copying part 2 constant by the force sensor 10.
