摘要: An industrial robot of the articulated arm type comprises a movable robot body (11) arranged on a base (10). An upper arm (13) having root and tip portions is rotatably pivoted to the robot body (11) at the root portion thereof. A forearm (16) having rear and front ends is rotatably pivoted to the tip portion of the upper arm (13) at a portion between the rear and front ends. Preferably, a wrist assembly (20) includes two moving elements (21,22) which are rotatable about different axes in relation to the front end of the forearm (16). The moving elements (21,22) of the wrist assembly (20) are rotated about the corresponding axes by means of wrist drive units (27, 28), respectively. The wrist drive units (27, 28) include first sprockets (29, 36), respectively, each rotatably arranged in the rear end of the forearm (16). Drive motors (31, 37), each rotating the first sprockets (33, 39), are arranged on the rear end of the forearm (16 ), respectively. Second sprockets (33, 39) are operatively coupled with the wrist assembly (20) and arranged in the front end of the forearm (16). Rotational movements of the first sprockets (29, 36) are transmitted through wrapping connectors (34, 45) to the second sprockets (33, 39), respectively. The wrapping connectors (34, 45) are of endless assemblies which include chains (46, 47) and rods (48, 49), respectively.

At least parts of the stationary robot component and the movable robot components have airtight chambers (15, 16, 17) communicating with each other and intended to be kept at a pressure higher than a predetermined level which is higher than an external atmospheric pressure. Robot driving motors (18 to 23) for driving the movable robot components are arranged within the airtight chambers. A driving motor controller (27) for driving and controlling the robot driving motors is connected to the robot driving motors by means of electric cables arranged within the airtight chambers. Pressure switches (25) supply signals to the driving motor controller to stop the robot driving motors, respectively, upon detection of the pressure in the airtight chambers when the pressure in the airtight chambers drops below the predetermined level.

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.
