    摘要: A clamp (10) having a pneumatic cylinder (28) with an actuating rod (30) connected to one end of a drive arm (32) which has its other end attached to a crankshaft (19) which in turn has crankpins (20,22) eccentrically mounted thereon to drive inner and outer clamp arms (24,26) between retracted and advanced positions corresponding to open and closed positions of the clamp. The length of the drive arm (32), the extent to which the crankpins (20,22) are offset from the crankshaft (19), the specific portion of a quadrant through which the crankpins are rotated, and the distance between the application of the force to the clamp arms and the axes about which the clamp arms pivot all provide a significant mechanical advantage and an extremely large clamping force from relatively low pressure compressed air supplied to the pneumatic cylinder (28).

    摘要: The aim of the invention is to improve a gripping device comprising a guiding rail, a first gripping element resting on the guiding rail with a first gripping surface formed by a pressure piece of a gripping spindle and moveable in the gripping direction, a sliding clamp guided on the guiding rail, moveable along said rail and fixable by a first jamming element and an advance device which has a second jamming element which can rest on the guiding rail and a pivoted advance lever with its handle between the guiding rail and the gripping spindle clamping grip and a second gripping element resting on the guiding rail with a second gripping surface in a such a way that it can be applied to a work piece more effectively in ergonomic terms and that the work piece can be gripped completely. To this end, it is suggested that the advance lever should operate with a first pressure element between the second jamming element and the sliding clamp in such a way that when the advance lever is activated in the direction of the gripping spindle clamping grip, the sliding clamp is displaceable in relation to the second jamming element in the gripping direction.

    摘要: A work stop (56) for use on a machine vise (10) is received in a jaw plate (20,22) for such vise (10) and is securely locked in position. The work stop (56) is fixed in a groove (58) that is machined int a top edge of the jaw plate (20,22) or jaw, with a member (57) extending over the edge of the jaw plate (20,22) and adjacent the face of the jaw plate (20,22) that is used for clamping a workpiece. This permits the workpiece to be slid against the stop (56) before being clamped. The jaw plate (20,22) is removable mounted onto a fixed jaw (18) and is located precisely relative to the fixed jaw (18) so that the jaw plate (20,22) with the work stop (56) attached an be removed, and then replaced when the same part is to be machined again.

    摘要: A removable quick change jaw plate (38) for a vise (10) has a T-slot that receives a pull rod that extends into a bore formed in the vise jaw (26, 28). The pull rod is actuated to pull the jaw plate (38) toward the vise (10). A wedge clamp, actuated by a threaded element provides a clamping motion to hold the jaw plate (38) on the vise (10).

    摘要: Disclosed herein is a tool for swaging a bearing into an opening in a bearing housing, which apparatus is operable in confined spaces, such as in an aircraft application. The tool has a threaded elongated member or bolt that extends through the bore of the bearing. The tool also has a roller fixture assembly adapted to be positioned on one side of the bearing and positioned on one end of the elongated member. The roller fixture assembly has a number of rollers and a roller fixture shell that supports the rollers for engagement with the bearing to swage the bearing against the bearing housing. The bearing swaging tool also has a locating fixture assembly adapted to be positioned on the opposite side of the bearing from the roller fixture assembly. The locating fixture assembly is supported on the other end of the elongated member and includes a locating fixture with a first side adapted to be positioned against the bearing and bearing housing. The locating fixture assembly includes means for selectively controlling the amount of axial movement of the locating fixture with respect to the elongated member in response to rotation of the elongated member with respect to the bearing.
