  • Patent number: 6581261
    Abstract: A large size clamping device for detaching a bearing having three cambered base blocks is disclosed. An inner edge of each base block is formed with a thinner top cambered surface. Each side of the base block has a penetrating connecting hole. Three connecting rods are used to connect the three base blocks by each connecting rod passing through the connecting holes of two respective base blocks. Thereby, an area confined by the base blocks is adjusted by adjusting the connections of the base blocks and the connecting rods. Thus the clamping device is suitable for bearings of different sizes. Moreover, the forces between the bearing to be pulled out and the clamping devices are more uniform so that the bearing will not be harmed.

  • Patent number: 6164635
    Abstract: An improved vise with a fixed jaw and a movable jaw which is guided by a lead screw to move along a pair of ways guiding the movable jaw. The movable jaw is adjusted to maintain a face which is precisely parallel with a face of the fixed jaw. The movable jaw is constructed of an upper component which travels on the ways, and a U-shaped lower member which inserts and telescopes into the upper component. The two jaw members contact at a chamfered face which cants or tilts the upper jaw member so that the movable jaw construction can be leveled. Leveling assures that the upper and lower jaw members cooperate, thereby interacting with a tapered face between the two to change the relative angle. In effect, the movable jaw face is maintaining precisely parallel and overcomes off center mounting of a workpiece.

  • Patent number: 6158102
    Abstract: A gas turbine rotor stacking fixture includes upstanding bolts for reception in aligned bolt holes in superposed aft disk, wheels and spacers and upstanding alignment rods received in openings of the disk, wheels and spacers during the rotor stacking assembly. The axially registering openings enable insertion of thin-walled tubes circumferentially about the rim of the rotor, with tight tolerances to the openings to provide supply and return steam for cooling buckets. The alignment rods have radial dimensions substantially less than their dimensions in a circumferential direction to allow for radial opening misalignment due to thermal expansion, tolerance stack-up and wheel-to-spacer mismatch due to rabbet mechanical growth. The circumferential dimension of the alignment rods affords tightly toleranced alignment of the openings through which the cooling tubes are installed.

  • Patent number: 6131895
    Abstract: A device is provided for holding a printed circuit panel having two substantially parallel margins. The device has a frame and employs two grasping jaws to hold the first and second margins of the panel, respectively. An actuator coupled to one of the grasping jaws provides a force that tends to move away one grasping jaw with respect to the other grasping jaw and thereby provides a tension to keep the printed circuit panel plane. Since the printed circuit panel is grapsed by and traction is exerted on the two parallel margins, the panel is held with highly accurate planeness regardless of its dimensions and of its thickness. In This manner, the device for holding a printed circuit panel may accommodate panels with a wide variety of sizes.
