ABSTRACT:
The present invention relates to a tool head being movable between a component supply and a place, where a component is to be mounted. The tool head comprises a tool shaft (1). This can rotate in relation to the base structure of said tool head and is also axially displaceable in relation to said base. To reduce the inertia of the mass to be displaced and rotated the tool shaft (1) is irrotationally and axially movably supported in a front bearing (3). This front bearing (3) is rotatably and not axially movably supported in the base plate. The rotation of said bearing element (3) is realized by means of a driving motor (9) and a toothed belt (7). The shaft (1) is driven axially by a second driving motor (25) also provided with a driving belt (23). To this driving belt a support element (17) is attached. The support element (37) is guided by a linear guide bar (21) and is also connected to said tool shaft (1). This connection allows the rotational movement of said tool shaft (1) in relation to said support element (17) but not translational axial movements. In this way it is obtained that the movable element, in this case the tool shaft (1), has a small inertial mass as possible. The invention also relates to a tool shaft (1) of the kind mentioned.
