| 101 | Chucking device of workpiece in grinding machine | US807950 | 1985-12-12 | US4709512A | 1987-12-01 | Kimio Okubo; Hiroshi Nemoto |
| A chucking device of a workpiece to be ground in a grinding machine, including a rotatable housing, a pair of elastically biased weight bodies which are opposed in the housing so as to come away from and close to each other a pair of opposed clamp plates which are provided on the respective weight bodies for relative movement and which have openings defining a center insertion opening in which the workpiece is inserted, and an end plate which is secured to the housing for covering the housing. The clamp plates are capable of inclining in planes thereof. The workpiece is firmly held in and by the center insertion opening of the clamp plates at at least four points of the center insertion hole by the outward displacement of the weight bodies, due to the centrifugal force acting thereon when the chucking device rotates. | ||||||

| A butterfly-valve disc (10) is reconstituted by applying welding metal about its edge, rotating the disc with a lathe, and working the disc edge with a lathe tool. A spinner apparatus adapts the butterfly valve disc to be turned on the lathe. The spinner apparatus comprises two spinner mechanisms (A and B) for respectively attaching to opposite sides of the disc. Each of the spinner mechanisms includes a block (38), an elongated centering shaft (42) slidably mounted on the block, a spinner bar (48) fastened to the block for extending into a boss hole (22 or 24) on a side of the valve disc on which the spinner mechanism is to be mounted, and aligning bars (70 and 72) attached to the block for making contact with the side of the valve disc on which the spinner mechanism is to be mounted for holding a valve-disc axis (88) aligned with an axis (43) of the centering shaft. | ||||||
| 103 | Clamping arrangement | US300595 | 1981-09-09 | US4454689A | 1984-06-19 | Karl-Heinz Giebmanns |
| In a grinding or milling machine an improved clamping arrangement for holding one end of a tool blank having a portion with at least four sides in cross-section. The other end of the tool blank is held against a stationary holding member. The clamping arrangement includes a housing which is coaxially mounted on a drive shaft. A pair of clamping members are reciprocally mounted in the housing and are biased outwardly by means of a pair of coil springs. Each clamping member has a skewed planar surface at its free end. The skewed planar surfaces biasingly engage opposite edges of the tool blank so as to compensate for any misalignment of the tool blank with respect to the holding member and clamping arrangement. | ||||||

| A lathe work center device centers a workpiece about an axis of rotation on a lathe. The lathe has two tool centers with at least one tool center being driven and both tool centers coaxially positioned about the axis of rotation. The work center device includes a substantially flat main ring portion having an outer periphery. A plurality of spurs integral with the main ring portion project toward and are embedded within the workpiece. The spurs are positioned on a side of the ring portion that is adjacent to the workpiece, proximate the outer periphery. A centering portion integral with the main ring portion projects outwardly therefrom on a side of the main ring portion opposite the spurs. Preferably, the centering portion has a frusto conical configuration and engages the tip of a tool center, locating the workpiece about the axis of rotation. A plurality of lugs proximate the outer periphery engage cooperating slots in the driven tool center for rotating the workpiece. | ||||||
| 105 | Locking head | US3753570D | 1972-05-23 | US3753570A | 1973-08-21 | ESPASA A |
| A movable locking head which includes a hollow housing having a tapered end for engaging an annular member and containing an actuator which moves two or more locking arms mounted thereto through openings in the tapered end of the housing into locking engagement with the inner periphery of the annular member.
