Embodiment Construction

[0036] At the outset, it should be noted that in the differently described embodiments, the same parts have the same reference numerals or the same component designations, wherein the disclosure content contained in the entire description can be transferred to The same part of the diagram label or component name. The positional specifications selected in the description, eg top, bottom, side, etc., relate to the directly described and illustrated figure and, in the event of a change in position, are automatically transferred to the new position.

[0037] exist figure 1 A perspective view of the articulated-arm robot 1 is shown in . The articulated-arm robot 1 comprises a base 2 which is fixed to the ground of the establishment site, preferably by means of fastening means. For example, it is also conceivable that the base 2 is arranged on a linear guide such that the complete articulated-arm robot 1 is movable in the longitudinal direction.

Abstract

The invention relates to an articulated-arm robot (1) and to a method for machining a workpiece by means of the articulated-arm robot (1). The articulated-arm robot (1) comprises: a base (2); a working head holder (7); a plurality of lever arms (3) which are arranged between the base (2) and the working head holder (7), the lever arms (3) being coupled to one another by means of revolute joints (4); a working head (8) which is arranged on the working head holder (7), the working head (8) comprising a working spindle (9) which is arranged in a spindle housing (13) and is mounted in the spindlehousing (13) at least at a first bearing point (14) and a second bearing point (15). At least one sensor (16) for sensing a radial force (17) is formed at each of the first bearing point (14) and thesecond bearing point (15). At least one sensor (18) for sensing an axial force (19) is formed at at least one of the two bearing points (14, 15).

Description

technical field [0001] The invention relates to an articulated-arm robot and to a method for machining workpieces by means of an articulated-arm robot. Background technique [0002] Articulated-arm robots are known from the prior art, which have a working head with a working spindle accommodated in a spindle housing. A machining tool is clamped in the work spindle. Forces are exerted on the articulated-arm robot by pressing the machining tool against the workpiece to be machined, the articulated-arm robot being slightly deformed by said force. Inaccuracies in machining workpieces due to deformation of the articulated arm robot. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the prior art and to provide an improved articulated arm robot and an improved method for machining workpieces. [0004] This object is achieved by devices and methods according to the claims. [0005] An articulated arm robot is constructe...
