摘要:
The present invention is intended to expand the operating region of a driven robot component of a robot by a provision of a driving linkage system for transmitting a drive torque of a drive source unit to the driven robot component, the driving linkage system having two spatially separated linkages, which are different from each other in the phase of motion thereof, to thereby transmit the drive torque from the drive source unit to the driven robot component by at least one of the two linkages even if the other linkage is brought to a dead center state, whereby the torque can be continuously transmitted to the driven robot component.

An industrial robot rotation shaft apparatus according to the invention has a waterproof structure obtained by providing the outer surface of a rotatable support (3) with an integrally formed, peripheral skirt portion (3c). A stationary support (2) is provided with a complementary, projecting collar portion (7b) substantially conforming to the inner surface of the skirt portion. The two complementary elements oppose each other while maintaining a small clearance therebetween. This makes it possible to shut out dust, water droplets and the like which would otherwise penetrate the interior of the robot from outside. As a result, rusting of the internal parts and the motor due to water droplets and debris penetrating the same is prevented.

A system for controlling acceleration and deceleration of a horizontally articulated robot computes the distance from the center of rotation of the robot (A) having a plurality of arms (3, 5) angularly movable in horizontal planes to a reference position such as a wrist (51) at the distal end of the arms (3, 5), and establishes an acceleration for the movement of the distal end of the arms (3, 5). A servomotor for angularly moving the arms (3,5) can effectively be utilized and the arms (3, 5) can quickly and smoothly be moved.

A system for converting the welding conditions of a welding robot includes a numerical control unit, which is for controlling the welding robot (8) and a welding machine (7). A memory (3) is included for storing a calculation sequence of a general expression of a given straight line obtained from an X value of a point (U=0) on the given straight line and the slope of the given straight line on a plane in which a welding condition input value is plotted along the X axis and a command value delivered to a digital/analog converter that applies commands to the welding machine is plotted along the Y axis. A value is obtained by substituting a welding condition input value, which is applied when the welding robot is taught, into the general expression stored in the memory (3), the value obtained being adapted as an output value supplied to the digital/analog converter.

A shaft supporting mechanism of an industrial robot in which an arm is supported by a freely extendable support shaft inside a hollow post and a working plane of a working arm is variably set is provided, with plural sets of linear support guides in opposed relation about a drive mechanism of the support shaft. As a result, the support shaft is held in the post stably and balanced in the vertical direction even if an external force attempting to tilt the support shaft is applied during up-and-down movement of the support shaft or operation of the working arm.

A hand changing device for industrial robots, having a changer body (10) designed to be attached to the robot arm (92) and a changer adapter (50) carrying a robot hand. The changer body (10) and the changer adapter (50) are separate components designed to be coupled detachably. The changer adapter (50) carrying the robot hand (74) is clamped by the changer body (10) by the engagement of a plurality of clamping balls retained within the changer body (10) and a ball engaging part formed in the changer adapter (50). The changer body (10) is provided with a fluid-driven piston (20) to move the clamping balls between two positions, namely, the clamping position and the idle position.
摘要:
A welding method in an automatic welding machine in which welding is performed by impressing a voltage across a wire, which is transported along a welding path by a robot, and a workpiece to produce an arc at the tip of the wire, and transporting the wire tip along the welding path by the robot while the wire is successively laid out in small increments. The method includes storing a number of welding conditions in memory which conditions comprise welding voltage, wire feed speed, preflow duration, crater processing duration and postflow duration selecting prescribed welding conditions by the program, jetting a gas toward the workpiece for the preflow duration; thereafter generating a selected welding voltage and laying out the wire at a selected wire feed speed to start welding. The welding conditions are selected by the program at a welding starting point, and a predetermined welding voltage is generated for the crater processing duration, followed by performing crater processing by laying out the wire at a predetermined wire feed speed, and thereafter performing postflow processing by jetting gas toward the workpiece for the postflow duration; these welding conditions selected by the program at a welding end point.

A double hand for an industrial robot comprises a hand body, two sets of work clamping units and two sets of actuators to drive the work clamping units, respectively, for opening and closing motions. The hand body has a rear end attachable to the free end of the robot wrist of an industrial robot, a front end and opposite sides extending between the front end and the rear end. Each work clamping unit has a pair of gripping fingers and the pairs of gripping fingers of the two sets of work gripping units are supported pivotally at the roots thereof on the opposite sides of the hand body for turning motion. The paired gripping fingers are turned about the respective roots thereof in opposite directions by the associated actuator.
