Abstract:
An industrial robot which allows its reduction gear to be easily replaced. An intermediate member (6) which includes a disk portion (61), a flange portion (63) provided around the periphery of the disk portion (61) and a through-hole (64) formed in the center of the disk portion (61) is provided between a rotating part (3) and a reduction mechanism part (22) of a reduction gear (2) fixed to a base (1). A through-hole (32) which is concentric with a rotating shaft (S) and has an inner diameter larger than the outer diameter of a fixing portion (21) of the reduction gear (2) is provided in the bottom (31) of the rotating part (3). The fixing portion (61) of the intermediate member (6) is fixed to the top surface of the reduction mechanism part (22) and the flange portion (63) is fixed to the bottom (31) of the rotating part (3) so that the bottom surface of the rotating part (3) is opposed to the top surface of the base (1) across a gap. A driving motor (4) is fixed to the disk portion (61) of the intermediate member (6) concentrically with the rotating shaft (S), and an output shaft (41) of the driving motor (4) is connected to the reduction mechanism part (22).
Abstract:
An industrial robot (10) having a rotary base (26) on a cylindrical stationary robot body (14), and robot arms (60, 64) and a robot wrist (66) in a robot arm unit at the free end portion of the rotary base (26) is provided with a cable guide (30) along the outer side of the stationary robot body (14). The lower end portion of the cable guide (30) is pivotably connected to the stationary robot body (14) via a lower bearing member (42), and the upper end portion of the cable guide (30) to the rotary base (26) via an upper bearing member (40), in such a manner that the cable guide (30) can be turned. A robot cable (50), which has the starting point at the lower end of the stationary robot body (14), is retained by a cable holder portion (32) formed at the intermediate section of the cable guide (30), and the upper end of the robot cable (50) is guided to the robot arm unit through the rotary base (26).
Abstract:
The invention concerns a multiple axis industrial robot (1) with a frame (2), an arm (7), an extension arm (13) and a robot hand (18), these elements being mounted so as to articulate with one another and drive-operated. The arm (7) is over-mounted on one side of the frame (18, 14) and situated to one side of the system plane (21). The arm (7) is connected to a static hydraulic mass balance (23) located on the same side of the system plane as the arm. The extension arm is likewise over-mounted on one side of the arm (7) and located with the arm bearing head (32) of the frame (2) within the system plane (21).
Abstract:
A multi-axis industrial robot consists of a frame (2), a rocker (3) which can rotate and swivel, a swivelling cantilever (6) and a multi-membered robot hand (8) which can rotate and swivel and whose members are driven by motors (10, 11, 12) arranged on the cantilever (6). The cantilever (6) is mounted (27) on one side on a one-armed rocker (4). At least two motors (10, 11, 12) are arranged side by side on the cantilever in the direction of its swivelling axis (7). In a three-motor arrangement, the motors (10, 11, 12) are arranged with their axles (13) in a short-sided triangle the base of which faces the bearing (27) of the cantilever (6). Alternatively, the motors are arranged with their drive side (15) facing the robot hand (8) and located close to each other and at a distance behind the bearing (27) at the end of the cantilever (6) or, when in the rotated position, with their drive side (15) remote from the robot hand (8) and level with the bearing (27).
Abstract:
A structure for supporting a bearing in a wrist of an industrial robot, in which the bearing (19) is unitarily insert-molded in the inner surface of an outer support member (10) with the inner projecting end portion of the bearing (19) held between an outer projecting portion (12') of a shaft (12) and a support member (15), the outer support member (10) being fixed to a support base (11). This bearing support structure is used for an industrial robot.
Abstract:
A device for carrying and adjusting a tool has a frame (2) and a base member (3) which is rotatably connected to the frame (2) about a first axis (Al). A main arm (5) is pivotally connected at one end to the base member (3) and at the other end to a lifting-arm holder (8). A yoke (7) is pivotally connected at its central portion to the main arm (5) at some distance from said one end thereof. The piston rod part (11a) of a first cylinder assembly (11) is pivotally connected to a projection (6) projecting at an angle from the main arm, and its cylinder part (11b) is pivotally connected to one arm (7a) of the yoke (7). The piston rod part (12a) of a second cylinder assembly (12) is pivotally connected to the base member (3), and its cylinder part (12b) is pivotally connected to the other arm (7b) of the yoke (7). A link arm (13) parallel to the main arm (5) is pivotally connected at one end to said other arm (7b) of the yoke (7) and pivotally connected at its other end to the lifting-arm holder (8). A lifting arm (9) is rotatably mounted in the lifting-arm holder (8) for rotation about its own axis (A) which extends perpendicularly to the parallel axes (A2, A3, A4, A5, A6, A7, A8, A9, A10) about which the main arm (5), the base member (3), the lifting-arm holder (8), the yoke (7), the cylinder assembly (11), the projection (6), the yoke arms (7a, 7b), the cylinder assembly (12), and the link arm (13) are pivotally interconnected. A tool holder (14) for the tool (15) is carried by the lifting arm (9).
