Abstract: Systems and methods of providing support to a mirror assembly including a high-stiffness, low mass structure. An L-shaped support, in conjunction with a shelf member and a plurality of fingers, provides support to a chuck upon which an operation (such as a wafer inspection) can be carried out. Materials such as ALBEMET and INVAR can be used to reduce mass and increase stiffness to avoid resonance in the system. Sensors and actuators can be employed to sense input energy and adjust the structure, respectively, if resonance is deemed likely.

Abstract: A replaceable chuck for a percussion hand-held power tool (3) for applying axial blows to a working tool receivable in the chuck, includes a release sleeve (4) axially displaceable relative to the base body (6) against a spring-biasing force and including an inwardly located locking element (11) for formlockingly securing the chuck on a power tool spindle (15) with locking elements (12) extending through respective openings (13) formed in a base body (6) and engageable in associated recesses (14) of the power tool spindle (15), and a formlocking displacement guide (5) that provides for displacement of the release sleeve (4) relative to the base body (6) and includes, along its axial extension, a tangential section.

Abstract: A tool bit and collet assembly, and method of assembling, wherein there is a collar for holding the collet in the radially inward position to thereby hold the tool bit. Camming surfaces are between the tool bit and the collet, and between the collet and the collar, for opening the collet upon insertion the tool bit into the collet, and thereby move the collar to the opening position.

Abstract: A fixed length collet chuck assembly for holding a workpiece in which the collet only translates radially and not axially is provided. The fixed length collet chuck has a longitudinal, central axis and includes a chuck body assembly and a collet. As a draw tube is pulled toward the spindle of a machine, such as a lathe, a tapered actuator forces ball bearings against a retaining plate and the ball bearings are forced radially outwards causing a taper ring to move axially away from the spindle and into contact with a bushing ring. The bushing ring is connected to a collet sleeve through three bushings which are radially and equally spaced around the longitudinal, central axis of the assembly. The inner surface of the collet sleeve tapers outward from the longitudinal, central axis of the assembly. A collet bears against the inner tapered surface of the collet sleeve.

Abstract: To provide a chuck assembly which is superior in practical usability and workability in clamping and fixing a tool to a spindle without fail and with ease by lever-operation of a specialized operational jig, a taper portion is provided on at least one of an inner circumferential wall of the sleeve portion and an outer circumferential wall of the tool clamping portion, the tool clamping portion and the sleeve portion are brought into contact with each other at the taper portion, a retainer portion for retaining the operational jig is provided on the sleeve portion, a support portion is provided in a predetermined position of the chuck assembly body for supporting the operational jig retained at the retainer portion, the sleeve portion retained by the operational jig is slidingly moved relative to the tool clamping portion when the operational jig is lever-operated in a taper direction of the taper portion by using the support portion as a fulcrum, and the opening portion of the tool clamping portion is widened

Abstract: A rotary power tool is provided having a remotely actuated chuck device. The chuck includes an outer sleeve member that is axially movable relative to the drive spindle between a gripping and release position. A sleeve actuating device is provided having a first member engaged with the outer sleeve member and which extends generally radially outward from the drive spindle or chuck. The first member is movable in a direction so as to move the outer sleeve member between the gripping position and release position. The sleeve actuating device includes an actuator member configured with the first member to move the first member upon an external force being applied thereto. The actuator member is generally perpendicular to the axis of the drive spindle and may be limited in length to be confined in the perimeter of the casing. In this manner, an operator can move the chuck device between the gripping release positions at a location remote from the chuck device and drive spindle.

Abstract: The invention relates to a collet device, in particular for snap closure attachments for gaseous and/or liquid media which comprises a clamping plunger and a plurality of collets each with a connection end and a bearing end. The bearing ends of the collets are detachably suspended on the clamping plunger and the collets can be displaced axially with the clamping plunger using an actuating member. For simple and rapid replacement and assembly of the collets the invention proposes that the collet arrangement is linked to a fixing member movable in relation to the collet arrangement in order to block the bearing ends positively.

Abstract: A spindle centered on an axis and formed with an axially forwardly open recess centered on the axis is secured to a tool holder formed with a tubular extension projecting axially rearward and fitted complementarily in the recess by a mount having an actuating rod axially displaceable in the spindle and having a head in the recess formed with an inner frustoconical surface directed rearward toward the collar and an outer annular surface generally perpendicular to the axis and also directed rearward toward the collar. A retaining element on the rod in the tubular extension has a plurality of segments forming a frustoconical inner front face directed forward toward the head, an outer annular face generally perpendicular to the axis and also directed forward toward the head, and a rear face directed axially rearward.

Abstract: A collet-operating mechanism utilizes an array of wedge members for the transmission of closing force to the pressure collar. The wedge members are of flatted barrel-shaped configuration to optimally cooperate, in line contact relationships, with bearing surfaces on the pressure collar and the supporting sleeve member.

Abstract: A collet-operating mechanism utilizes an array of wedge members for the transmission of closing force to the pressure collar. The wedge members are uniquely configured to optimally cooperate with a convexly arcuate bearing surface on the supporting sleeve member, to effect closure with greater facility and to produce an increased level of force amplification. In addition, the wedge members are of such form as to make feasible manufacture by conventional machining operations.
