    摘要： A power tool includes a motor assembly, a base assembly, and a clamp assembly coupled to the motor assembly or the base assembly to selectively provide a retention force to the other to removably couple the motor assembly and the base assembly. The clamp assembly includes a handle member, a fulcrum member, and a biasing lever member. The lever member includes a first portion and a second portion disposed on opposite sides of the fulcrum member. The handle member is coupled to the first portion, and the handle member is movable between an open and closed position. The handle member rotates the first and second portions of the biasing lever member about the fulcrum member when moving from the open to the closed position, causing the second portion of the lever member to provide the retention force.

    摘要： A machine tool has a table body (3) and a drive line on a bed (1). The table body (3) is linearly movable via a guide member (4) having a sliding or rolling guide surface. The drive line has a ball screw (5) or the like, and moves the table body (3) along the guide surface. A pair of the guide members (4) are provided at positions in point symmetry about the position of the center of gravity (G) of the table body (3). Moreover, a pair of the drive lines having the ball screws (5) or the like are provided at positions in point symmetry about the position of the center of gravity (G) of the table body (3). Alternatively, the drive line having the ball screw (5) or the like is provided at the position of the center of gravity (g) of the table body (3). The machine tool can effectively suppress vibrations of a structure (such as the bed) generated during movement of a moving object (such as the table body) relative to the structure by the drive line, thereby shortening the machining time and increasing productivity.

    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).
