    摘要: @ Means for mounting a workpiece holder such as a collet on a support element such as the arbor of a machine tool in preparation for machining comprises a support member (10; 100) for attachment to the arbor and a plate member (60; 150) carrying the collet, the support member and the plate member having respectively a frustoconical boss (55; 152) and a complementary recess (88; 102). The support member has latch elements (38; 104) which move in and out under the control of a locking ring (44; 130) and engage groove means on the plate member. The workpiece mounting can thus be changed rapidly and reliably with most of the set-up being carried out away from the machine tool.

    摘要: A spindle lock-up device (11) is provided for releasably locking a rotary spindle (1) having a tool holder (9) to a non-rotatable support (2), such as the ram of a vertical boring machine, so that the spindle tool holder (9) also may be used as a fixed tool holder for the ram (2). The device (11) has a first spiroid gear member (14) fixed to the ram (2), a second spiroid gear member (17) fixed to the spindle (1), and a third spiroid gear member (19) surrounding the spindle (1) and mounted for axial movement from a retracted to an extended position, the third gear member (19) simultaneously engaging the first (14) and second (11) gear members when in the extended position to lock the spindle (1) against rotation relative to the ram (2). The third gear member (19) is moved to the extended position by a piston (25).
