摘要:
A vibration-absorbing end effector of an automated drill and countersink machine having a shock to mitigate communications of vibrations to the drill tool, while simultaneously dampening the vibrations at their source, in order to increase control of a drill tool during drilling and countersinking operations. The end effector comprises a measurement scale to ensure that the depths of holes to be drilled and countersunk can be checked and corrected in accordance with corresponding ideal depths stored in a memory of the computer already interfaced to the end effector. Furthermore, the pressure foot of the end effector is upwardly rotatable to access the drill tool to the chuck.

A roll grinder system including a roll grinder bed of high dynamic stiffness, having a roll support and a grinding wheel support fixedly mounted to the roll grinder bed. The roll grinder bed is comprised of a monolithic epoxy granite block with a steel plate embedded in the top surface and a steel plate embedded in the bottom surface. The bed for the support for the roll being ground is rigidly affixed to the top plate. The bed for the traversing carriage of the grinding wheel head is also rigidly affixed to the top plate. A bed for the caliper is affixed to a lateral side of the block. The grinding wheel and the caliper traverse along the axis of the roll being ground. Vibration isolators are disposed below the bottom plate of the block.

An outer shaft gear installed at an external side of a pivoting shaft for pivoting a tool exchange arm main body is fitted to a finger driving cam shaft, a driving force from an ATC drive shaft is transmitted via the outer shaft gear to a finger driving cam installed to the finger driving cam shaft, and a driven portion in contact with the finger driving cam is operated by which fingers FA and FB at front ends of pairs of fingers are opened. When the fingers FA and FB are not pressed by the operation of the finger driving cam, the fingers FA and FB are closed by urging forces of springs.

A flexible mounting system principally developped for ring-type log debarkers comprises a combination of freely oscillating supporting links and weight compensating pneumatic devices, arranged in such a way as to allow the working tool assembly of the debarker to move in any direction in response to external forces exerted upon it by the longitudinal feed motion or the shape irregularities of the log.

A supporting mechanism is provided in which each of three supporting portions is constituted by an elastic member able to be deformed only in one direction and an oscillation mechanism which can oscillate around the axis parallel to the one direction.

A removable cutterhead insert for use in a helical cutterhead for an industrial woodworking machine, the helical cutterhead including a generally cylindrical portion, a plurality of circumferential, spaced grooves extending into the cutterhead body from the periphery of the cylindrical portion and adapted to receive the removable cutterhead inserts, and fasteners for removably securing the cutterhead inserts in the grooves; the cutterhead insert includes a mild steel insert body and two blade units; the insert body having raised portions having triangular pockets formed therein so as to have two inwardly-facing flat portions, a hole to receive the fasteners for removably securing the cutterhead insert in the grooves between the inwardly-facing flat portions and two bolt holes to secure the two blade units to the insert body; and the blade units are triangular with cut-off corners each including a blade edge and configured so as not to occlude the countersunk hole and to have the blades edges disposed to align with the blade edges of other blade units in other insert bodies to form a substantially helical blade when the blade units are secured to the insert body in a cutterhead.

The NC complex automatic lathe is provided with a main spindle receptive therein a workpiece for chucking the same such as to protrude a front end portion of the workpiece, and a main spindle base for supporting the main spindle rotatably around a center axis and displaceably in a lengthwise direction of the workpiece. A turret type tool slide is disposed in the vicinity of the front end portion of the workpiece. The turret type tool slide is displaced transversely toward the center of the workpiece. A plurality of tool slide members are arranged radially around the front end portion of the workpiece in a free space away from the moving area of the turret type tool slide such as to undergo displacements toward the center of the workpiece.
摘要:
A damped, cantilevered support arm for a machine tool position monitoring device rigidly attached to the machine tool by a pair of spaced bolts for relative movement with a machine part along a longitudinal axis. The line of centers through the bolts is oriented along the longitudinal axis and the arm is mounted with shims located between its base and the machine tool part to allow limited effective freedom of movement of the support arm around the line of centers in a direction normal to the longitudinal axis. A squeeze-film damping chamber is provided between the spaced shims for reducing the response of the support arm in the normal direction during relative movement along the longitudinal axis. A boundary O-ring seal together with the thickness of the spacers, defines the damping chamber. Multiple degrees of freedom of movement and support arm response can also be accommodated by a stacked squeeze-film arrangement, wherein an oriented, rocking damper plate is sandwiched between the machine and support arm.
摘要:
An elongate chain member having first and second ends is arranged for biased securement relative to the first and second ends for mounting peripherally about a brake rotor during a training procedure to dampen vibrations and audible noise. The invention is arranged to further include vibration dampener blocks within individual links of the chain member.

The engine and other machinery within a marine vessel is mounted on a raft which is relatively flimsy compared with conventional constructions. The raft is supported by electromagnets, the current to which is controlled so as to avoid vibration and flexing which would otherwise take place and so as to reduce transmission of vibration to the hull and other parts of the ship.
