Abstract
A device for positioning and locking turning, milling or other tool holders onto mobile slides with an internal spindle, comprising a first sytem (14) of conventional type for machining centers which is designed to lock tools (37) usually carried by this type of machine; the device also comprises two diametrically opposing levers external to the slide (10), which are hinged (31) to the slide (10) and each comprises two end teeth (32, 33), of which the first (32) is opposite a projection (29) on the piston (28) of a hydraulic or pneumatic cylinder (23), and the second (33) is arranged to engage in a tool holder (43) of a lathe tool (42) in order to lock it; the locking condition occurs when the piston (28) carrying the projection (29) has moved under the action of spring (27) so as to press against the opposing tooth (32) of the lever (30), so rotating this latter (30) such as to cause its other tooth (33) to engage in the tool holder (43); the release condition occurs when the piston (28) carrying the projection (29) has moved against spring (27), so as to cause the opposing tooth (32) of the lever to abandon the projection (29) such that the lever (30), urged by its spring (35), r…
