A device for locating, at an accurate, predetermined position on a tool table (2), a tool (1) which, on its underface, has a guide pin (7) which guidingly slides in a guide groove (6) in the tool table (2) when the tool (1) is displaced therealong towards the predetermined position. The tool table is provided with two guide heels (8, 8'), which are spring-loaded upwardly and which, by means of bevels (10, 10') on the tool (1), are depressible in the tool table (2). The guide heels (8, 8') are located in grooves (5, 5') one on either side of the guide groove (6) or its prolongation. The underface (12) of the tool (1) is provided with recesses (13, 13') for the guide heels (8, 8'), so that the displacement of the tool is thereby arrested in the predetermined position when the guide heels (8, 8') snap up out of the recesses (13, 13') under their spring loading. |
