  • Patent number: 6874219
    Abstract: A disk clamp for securing disks to the hub of a spindle motor in a disk drive has symmetrically spaced apart countersunk apertures in the top surface of the disk clamp. The apertures enable the disk clamp to maintain a proper orientation before the fasteners are attached. This design overcomes issues related to rotation and displacement of the clamp while it is being fastened to the hub, and reduces the complexity of the tooling and fixtures required to complete the assembly. Less tooling complexity also allows multi-fastener driver systems to be employed so that all of the fasteners required to complete the assembly may be simultaneously attached arid driven into the disk clamp. The countersunk apertures on the disk clamp are designed to couple with tapered sleeves on the installation tool to quickly and precisely center the fasteners in the disk clamp while providing anti-rotation torque for the disk clamp.

    Abstract: An improved lead frame conveying apparatus for conveying a lead frame to a bonding position has two pins each with a tapered end which is provided for being inserted into a positioning hole in a lead frame. The tapered end has an upper portion the diameter of which is smaller than the diameter of the positioning hole in the lead frame and a lower portion the diameter of which is larger than the diameter of the positioning hole. The lead frame is supported by the tapered ends of the pins which engage the round edges of the positioning holes. The tapered pins are moved controllably in this state, thereby feeding the lead frame to the bonding position. Since the weight of lead frame tends to push the lead frame down on the pins, the centers of the positioining holes and the tapered pins become automatically aligned, bringing about correct aligning of the lead frame.

The first set of axially extending pins coacts with a second set of axially extending equalizing pins (30, 130) to clamp the workpiece therebetween. The first set of locating pins are located in a housing member (38, 138). The first set of pins also includes two fixed locating pins (48, 148) which contact the outer surface of the piston.

  • Patent number: 4708041
    Abstract: A lathe-mounting apparatus defining a cylindrical core having an enlarged cylindrical termination at one end thereof and a separate slidably-mounted cone at the opposite end. The cone is adapted to slide onto the smaller end of the cylindrical core, the smaller end of the cone preceding the larger end, whereby a brake disk, or other similarly shaped cylindrical article, mounted on the cylindrical core between the enlarged termination and the cone, may be cut or resurfaced without significant vibration during rotation of the article.

  • Patent number: 4646419
    Abstract: An apparatus (10) for engaging a printed circuit board (12) positioned in rough alignment therewith comprises an housing (14) having a bore (16) which is partially tapered (20). Loosely mounted within the bore is a sleeve (24) having a tapered portion (30) complementary to the tapered portion (20) of the bore. A pin (36) is spring-biased within the sleeve and extends therefrom beyond the housing for insertion into a tooling hole (76) in the printed circuit board upon movement of the sleeve into the bore in the housing. While the tapered portion (30) on the sleeve remains spaced from the tapered section (20) of the bore, the pin is capable of limited lateral movement about the axis of the bore which virtually eliminates wedging or sticking thereof in the tooling hole. Once the sleeve is fully inserted into the housing, the tapered portion on the sleeve nests with the tapered section of the bore, rigidly locking the pin in place.

  • Patent number: 4638985
    Abstract: In a sheet holding apparatus having a pair of parallelly disposed rails (17, 18) for sliding a sheet, such as a printed board, and plural guide holders (38, 42) having plural positioning guide pin (40, 44) to be inserted in holes of the printed wiring board, distance between the pair of rails (17, 18) is changed by a screw shaft (20) which is rotated by a driving motor (32) responding to change of size of the sheet, and a spline shaft (36) is disposed along the rails (17, 18), and the guide holders (32, 42) are provided to be slidable on the spline shaft (36), which puts up and down the guide holders (32, 42), hence positioning guide pins (40, 44) above and below a level of carrying plane of the sheet by rotation thereof.

  • Patent number: 4632373
    Abstract: A fixture for use in conjunction with welding workpieces by vibration welding including a pin adapted to assume two states, namely a first state in which the pin is movable to seek an aperture in the workpiece and is free to enter such aperture, and a second state in which the pin is rigidly fixed. The pin is attached to a plate which responsive to fluid pressure is either free to float in a generally lateral direction, or is clamped rigidly between two superposed plates.

  • Patent number: 4624043
    Abstract: A releasable tool holder (75) for quickly interchanging tools usable by a conventional robot (50) having one or more articulatable arms (60, 65, 70). The tool holder (75) is mounted to an arm (70) of the robot (50) and is provided with a plurality of variable fulcrum clamping levers (110) capable of engaging a surface (215) of a ring (205) mounting a preselected tool. A fluid motor (95) is connected to a translatable center link (105) that is pivotably attached to the variable fulcrum clamping levers (110) whereby when the motor (95) causes the link (105) to translate, the variable fulcrum clamping levers (110) engage the surface (215) of the tool mounting ring (205). A novel tool mounting ring (205) and a releasable fluid coupling (125) are also provided.

  • Patent number: 4545570
    Abstract: A highly accurate rapid gimbal assembly method utilizes two fixtures for establishing the critical gimbal assembly parameters of yield and axis of intersection and an adhesive for bonding each mating surface of the gimbal assembly for holding the components of the gimbal assembly in their adjusted positions. The fixtures include an inner/outer gimbal fixture for holding the inner and outer gimbals in relative position for bonding and a gimbal/post fixture for holding the gimbal assembly in alignment on the support post for bonding. These fixtures and assembly method eliminate the need for use of shims between the mating surfaces for establishing alignment of the critical parameters.

  • Patent number: 4487110
    Abstract: A clamping element comprises a single-acting cylinder and a piston with strong spring return which can be cancelled out by introduction of a pressure medium into the pressure chamber of the cylinder. The spring return is brought about, at least mainly, by means of a sleeve (6a, 6b) of rubber or rubber-like material which occupies a gap (5, 5b) between the piston (3, 3a, 3b) and the cylinder wall (7, 7a, 7b) or a lining (40) arranged in the cylinder. The rubber sleeve is firmly vulcanized, firmly glued or surface-fixed in some other manner against the cylindrical exterior of the piston and against the wall of the cylinder or the said lining along an axial length which considerably exceeds the thickness of the gap.
