摘要： A parallel power chuck for clamping two ends of a shaft or similar workpiece for machining using two centering mechanisms. The centering mechanisms independently operate from a single internal actuation mechanism and clamp each end of the shaft regardless of shaft size from end to end. The internal actuation mechanism further equalizes applied clamping force after compensating for size variation.

摘要： A work holder assembly for use in clamping a workpiece being machined. A chuck includes a fixed sleeve about which is mounted a rotatable collet. A plurality of individual clamps extend from circumferential spaced locations associated with the collet. The clamps each include a first spring biased and linear traveling component actuating a second radially traveling and adjustable component into engagement with annular disposed locations of the workpiece. Each the clamps exhibits a wedge shape at an interface between the linear and radial components, both in order to minimize clamping forces and to prevent backdriving of the clamps by the tooling. A fluid pressure extends through a location in the chuck, the collet further having a fluid delivery component in communication with the fluid supply and which is in contact with workpiece engaging locations, to overcome the spring bias of said pin in a fluid actuated release condition.

摘要： A chuck assembly for use in a substrate spin, rinse, and dry (SRD) module is provided. The chuck assembly includes a wedge, a chuck body, and a plurality of grippers. The wedge has a sidewall and is designed to move from a lower position to an upper position and from the upper position to the lower position thus opening and closing the chuck assembly, respectively. The chuck body has a cylindrical shape and is designed to include a plurality of linkage arms. The chuck body is designed to enclose the wedge such that each linkage arm is substantially in contact with the sidewall of the wedge. The cylindrical shape of the chuck body is designed to reduce air disturbance around a surface of a substrate. The plurality of grippers are designed to be coupled to the chuck body via a plurality of rotation pins. Each of the grippers is configured to stand substantially upright so as to engage the substrate when the wedge is in a lower position, and each of the grippers is configured to lie substantially flat so as to disengage the substrate when the wedge is in the lower position.

摘要： A combination of two or more jaw assemblies for mounting onto a self-centering power chuck to move an irregular workpiece to the axial centerline of the power chuck after it has been clamped. Each jaw assembly has a independent hydraulic system which, when activated, reduces the length of the jaw assembly, thereby moving the workpiece clamped in the power chuck. The imperfect pipe's average centerline can be moved to any location within the combined adjustable range of all the jaw assemblies. Each jaw assembly consists of a base jaw that is affixed to the power chuck, a connecting block that moves when the hydraulic system is actuated, a piston, a cylinder, and an interchangeable swivel insert with a serrated gripping surface.

摘要： A lathe chuck has a chuck body centered on and rotatable about a main axis and formed with a plurality of radially extending jaw-guide grooves and, transverse to the grooves, with respective guide passages each in turn formed with an abutment. Respective jaws displaceable in the grooves each have at least one tooth exposed in the respective guide passage and respective control rods displaceable along the passages each have at least one tooth meshing with the tooth of the respective jaw. A control pin is axially displaceable in each rod between an extended position projecting into the respective jaw-guide groove and a retracted position. The control pins are displaced on engagement with the teeth of the respective jaws into the retracted positions. A latch pin is axially displaceable in each rod between an extended latching position engaging the respective abutment and preventing movement of the respective rod in the respective passage and a retracted position permitting such movement. A spring urges the pins into their extended positions, and a coupling member engaged between the pins displaces the respective latch pin into the respective retracted position on displacement of the control pin into its retracted position. Thus, when there is no jaw in the guide groove, the latch pin of the respective control rod latches same against-movement in the respective passage.

摘要翻译： 车床卡盘具有以主轴为中心并且可围绕主轴线旋转的卡盘体，并且形成有多个径向延伸的卡爪引导槽，并且横向于槽与相应的引导通道分别依次形成有邻接件。 在凹槽中可移位的各个夹爪各自具有在相应的引导通道中暴露的至少一个齿，并且可沿着通道移动的相应的控制杆各自具有与相应的爪的齿啮合的至少一个齿。 控制销在每个杆中在伸入相应的爪引导槽的延伸位置和缩回位置之间可轴向移动。 控制销在与相应钳口的齿接合到缩回位置时移位。 每个杆中的一个闩锁销可在一个延伸的闩锁位置与相应的邻接件啮合之间轴向移动，并防止相应的杆在相应的通道中的运动以及允许这种运动的缩回位置。 弹簧将销钉推入其伸出位置，并且接合在销之间的联接构件在控制销移位到其缩回位置时将相应的闩锁销移位到相应的缩回位置。 因此，当引导槽中没有钳口时，相应控制杆的闩锁销在相应的通道中相同地相互锁定。
