Embodiment Construction

[0021] figure 1 An industrial robot 1 is shown, which includes a handling controller 2 and its control unit 3 . The robot 1 has a frame 4 rotatably mounted on a robot base 5 so that it can turn about a vertical axis A. As shown in FIG. The robot 1 has a robot arm 6 consisting of a lower arm 6a and an upper arm 6b. The lower arm 6a is pivotally mounted about the axis B and supports the upper arm 6b. The lower and upper arms pivot about axis C. The upper arm 6b is pivotable about an axis D which coincides with the longitudinal axis of the upper arm 6b.

[0022] A wrist 7 is attached to the end of the upper arm 6b. The wrist 7 comprises holding means 9 for pivotally connecting with one degree of freedom a rotary robotic tool comprising a spindle motor 8 arranged to drive a rotary tool accessory. The spindle motor 8 has an adapter 10 on which a rotary tool accessory can be mounted. For example, a rotary robotic tool is a drill and a rotary tool accessory is a drill. A drill...

Abstract

An industrial robot (1) comprising a robot arm having a wrist (7) comprising a wrist housing which is movably mounted on the robot arm (6), whereby the wrist housing comprises holding means (9) for pivotable connection in one degree of freedom of a rotary robot tool thereto.

Description

technical field [0001] The present invention relates to industrial robots. Background technique [0002] A conventional industrial robot comprises at least one robotic arm having a wrist at its end. The wrist includes a wrist frame with retaining means, such as a forked extension, in which is supported a tilting assembly. The wrist rotates about a first axis that is parallel to the longitudinal centerline of the robotic arm. The wrist also includes a rotating disk on which robotic tools or other desired accessories are mounted. The turntable is configured to rotate about a second axis at an angle to the first axis on the turntable to position the robotic tool. Such an industrial robot is disclosed, for example, in US patent 6,125,715. A disadvantage of such industrial robots is that there is an offset between the center of rotation of the rotating disk and the robot tool, which makes the robot unfavorably flexible and adversely affects its performance.
