摘要:
A fastener system for multi-piece swage type fasteners, including a pin (12) and a collar (14), and providing a stump type fastener (10) constructed to be set as a pull type fastener with the fastener pin (12) having a threaded gripping portion (34) and including a compact installation tool (44) having a swage anvil (50) and a rotary threaded member (46) adapted to be threaded onto the threaded pull portion (34) of the pin (12) whereby a relative axial force is applied between the pin (12) and the collar (14) via the rotary threaded member (46) and swage anvil (50) to cause the anvil (50) to radially overengage the collar (14) to swage it into locking grooves (32) on the pin (12) and the pull portion (34) remaining on the pin (12) after installation and with the swage anvil (50) being connected to a piston rod (104) of a piston (80) for axially reciprocating movement for swaging the collar (14) with the rotary threaded member (46) being axially fixed and with the swage anvil (50) and rotary threaded member (46) being offset from the remainder of the tool (44) whereby the tool (44) can be used to install such fastener (10) in application of limited clearance.

摘要:
A method of controlling a power assist device (50) that includes an operating handle (6), a force sensor (7), a robot arm (3), an actuator (11) that drives the robot arm (3), and conveying means (14) for conveying the robot arm (3). When a body (100) is in motion, the conveying means (14) is controlled to move in synchronization with the body, and when the motion of the body (100) is stopped or has resumed, the drive of the robot arm (3) is stopped for a predetermined time, and does not resume until after a predetermined time has elapsed.

摘要:
A force-controlling robot having a function of drawing a fitting part from a receiving part. A fitting part held by a robot hand is moved form an approach start position in a set approach direction under speed and force control. When the fitting part comes in contact with a receiving part and a reaction force thereof exceeds a set threshold value, the fitting part is moved under speed and force control with the set target speed and force and in the set inserting/fitting direction so as to perform fitting. If stoppage occurs before the fitting is completed, the fitting part is moved under speed and force control in the set drawing direction and with the set target drawing speed and drawing force, to draw the fitting part from the receiving part. As the drawing operation is automatically performed, restoration is automatically made without manual operation even if stoppage occurs in the fitting operation. Further, assembled parts can be automatically disassembled.
