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.

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.
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.

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.
Abstract: A pry tool for facilitating disassembly of suspension components in a vehicle wheel suspension assembly which includes a vehicular telescopic strut member secured to a steering knuckle. The tool comprises a handle member along with a fulcrum tower, with the combination being arranged to substantially enclose the strut, and through forces created by the pry tool, and against the coil spring, the tool enables and facilitates removal of the steering knuckle from the body of the strut. The pry tool includes an elongated handle with a handle yoke at one end for enclosing or enveloping the strut, and with a fulcrum yoke at the opposed end for contacting the upper end of the steering knuckle. Axial removal forces are applied between the coil spring and the steering knuckle, thereby freeing the strut component from the assembly.
Abstract: An eyeglass lens grinding machine, which is designed to effectively utilize the grinding capability of abrasive wheels so as to perform efficient grinding operations. The eyeglass lens grinding machine includes a lens rotating section which holds and rotates a lens to be processed, an abrasive wheel rotating section which rotates an abrasive wheel for grinding the lens on its own axis, an abrasive wheel's rotational state detecting section which detects the state of rotation of the abrasive wheel caused by the abrasive wheel rotating section, and a rotation control section which variably changes the rotation of the lens rotating section on the basis of the result of the detection. The rotation control section issues a command to either stop or slow down the rotation of the lens if the load on the rotation of the abrasive wheel exceeds a predetermined reference level and issues a command to have the lens rotation return to the initial state if the load becomes lower than the reference level.
