A tool changing apparatus for a machine tool comprising, adjacent an operating space, an indexable tool carrier displaceable in two feed directions defining a plane of movement and comprising a plurality of tool receiving means each including a holding means, which is provided with a clamping device, for inserting and securely clamping a base of a tool as well as a clamping element having a predetermined direction of movement for tightening and releasing the clamping device, and also comprising a tool gripping device having an actuating device adapted to be coupled to the clamping element. To avoid the necessity of moving a tool, which is to be interchanged, in two directions during tool changing, this tool changing apparatus is designed such that, in a tool receiving means, the slide-on direction of the holding means, the axial direction of the clamping element and the coupling direction of the actuating device for the clamping element are all parallel to one another and that the tool gripping device may be moved towards the tool receiving means transversely to the row formed by these tool receiving means and parallel to the slide-on direction.
A tool changing apparatus for a machine tool comprising a working space and an indexable tool carrier (16) located adjacent said working space and having a plurality of tool receiving means (30) forming a row, at least a number of said tool receiving means having a holding means (42) for sliding and clamping a base (40) of a tool onto the respective tool receiving means, at least one of said bases carrying an inside diameter working tool (32) having a tool axis, said holding means being provided with a clamping device (52) and adapted to be brought into a tool-changing position, as well as a clamping element (64) for tightening and releasing said clamping device, said clamping element having an axis, and with a tool gripping device (70) including an actuating device (110) adapted to be coupled in a coupling direction to the clamping element, means for displacing the tool gripping device (70) along a transfer path (E) towards a tool holding means located in tool-changing position in a direction of displacement being transverse to the row formed by said tool receiving means and transverse to the tool axis of an inside diameter working tool (32) located in tool-changing position as well as at least approximately parallel to the axis of said clamping element (64) of the tool holding means (42) located in tool-changing position, said coupling direction extending parallel to said direction of displacement of the tool gripping device, the improvement comprising:
