摘要:
The cable supporting arrangement inside the base body of an industrial robot supports at least a cable (14) led through the interior of the base body (10) having a cylindrical inner surface (11) into the movable body (13) provided atop the base body pivotably about the axis (X) of the base body. An inner cylinder (15) is provided and fixed concentrically inside the base body. An annular space is defined between the inner cylinder and the base body. The resilient strip members (19, 20) have one end (21, 30) thereof fixed to the inner surface of the base body, and the other end (22, 31) fixed to the cylindrical outer face (16) of the inner cylinder. The strip member is curved at a selected portion such that the strip member sections before and after the curved portion are opposite to each other, and is forced under its own resilience onto the inner surface of the base body and the outer face of the inner cylinder when the movable body is in a selected pivoting position. A plurality of cable holders ( 25, 32) are disposed and spaced from each other on one side of the strip member along the length of the latter to hold the cable.

A compact industrial robot for mounting on a lathe includes a traveling body transported along an axis (Z axis) parallel to the axis of a spindle provided on a lathe, a column provided on the traveling body for extending and retracting in a vertical direction (Y axis), a first rotating mechanism provided on the column for rotation about an axis (C axis) parallel to the spindle axis, and a second rotating mechanism provided on the rotary shaft of the first rotating mechanism and having a hand. The hand, having a double-hand configuration, is swung by the first rotating mechanism in a plane orthogonal to the spindle axis, and is swiveled by the second rotating mechanism about the longitudinal axis (.alpha. axis) of the second rotating mechanism.

An industrial robot comprises a robot body having an operating portion (13), a driving motor (19) for driving the operating portion (13) and the a handle (29). A casing (21) of the driving motor (19) is secured to an outer wall of the robot body by bolts (25), and an output shaft (26) of the driving motor (19) is connected to the operating portion (13). An inner brake device of the driving motor (19) secures the output shaft (26) to the casing (21) when the driving motor (19) is stopped. If the driving motor (19) is stopped by a malfunction or the like, the bolts (25) are taken out and the handle (29) is attached to the casing (21) of the driving motor (19). By operating the handle (29), the output shaft (26) of the driving motor (19) is rotated together with the casing (21) and the operating portion (13) of the robot is moved.
摘要:
A method and a device for determining the reference positions of an industrial robot, in which datum surfaces (1a, 1b) are formed in the fixed base (1) of an industrial robot having a plurality of degrees of freedom of motion. The reference positions with respect to directions corresponding to the degrees of freedom of motion of the wrist base (5) and the wrist front section (7) are determined relatively to the fixed base (1) by means of a jig body (11) located fixedly on the datum surfaces, and measuring instruments (14 to 19) attached to the fixed base (1) at predetermined reference positions thereon, and the determined reference positions are given and taught to the NC unit of the industrial robot.
摘要:
An industrial robot, having a manipulative robot hand for mounted on a vertically movable portion thereof moved by a vertical drive, provided with a load reducing pneumatic cylinder for applying a constant upward force to the vertically movable portion during the vertical movement of the portion and an air storage tank or tanks directly connected to the pneumatic cylinder for continuously supplying air under a desired fixed pressure. The upward force contributes to reducing a load applied to the vertical drive. The air storage tank or tanks contributes to ensuring mechanical rigidity of the industrial robot.
摘要:
A swivel device for supporting a swivel unit thereon, including a hollow main frame and a comparatively slender rotatable shaft disposed upright within the hollow frame, connectable to the swivel unit at the upper end thereof and connected to a driving source at the lower end thereof through a transmission mechanism. All control cables and conduits for controlling the mechanisms mounted on the swivel unit are accommodated in the space formed within the hollow frame around the upright shaft.
摘要:
A wrist mechanism of an industrial robot provided at the extremity of the robot arm (20) and having two degrees of freedom of motion enabling a wrist unit (30) to perform a tilting motion and a swivel motion about two substantially perpendicular intersecting axes respectively. Either a motion transmitting mechanism for the tilting motion of the wrist unit or a motion transmitting mechanism for the swivel motion of the wrist unit (80, 82, 90, 92, 96) is provided with a bevel gear mechanism (96) to change the direction of motion transmission through an angle of 90.degree.. Overtravel detecting means (110a, 110b, 120a, 120b) for detecting the overtravel of both the above-mentioned motions and datum position of motion detecting means (112a, 112b, 122a, 122b) are coaxially arranged about one of the above-mentioned perpendicular intersecting axes.

A wrist mechanism interposed between the robot arm (20) of an industrial robot and a robot hand, comprising: an outer wrist (34) joined to the free end of the robot arm (20); an inner wrist (36) pivotally supported by bearings (100, 102) within the outer wrist (34) and adapted to be pivoted by a driving force transmitted thereto through the robot arm (20); a robot hand holding part (38) supported by bearings (104, 106) within the inner wrist (36) and adapted to be turned by a rotative force transmitted thereto from the outside of the inner wrist (36) coaxially with the driving force; a bevel gear mechanism set having bevel gears (96a, 96b) and disposed within the inner wrist (36) to transmit the rotative force to the robot hand holding part (38); and a reduction gear (94) provided within the inner wrist (36) to transmit the rotative force at a reduced revolving rate to the driving bevel gear (96a) of the bevel gear mechanism.
摘要:
An industrial robot having a trunk mounted for vertical and rotational movement on a stationary base is provided with two arm members extensible from the said trunk having a robot wrist mechanism attached to their ends. The extending and contracting movements of the arm members, rotational movement of the wrist and swinging movement of the wrist are controlled, respectively, by three electric servo motors mounted in a mounting compartment positioned on the side of the trunk opposite to the extensible arms.
