摘要:
A rotary table assembly for supporting a workpiece can include a table having a table top surface positioned in a first plane, where the table has a first axis of rotation. The rotary table assembly can also include a support frame having a support surface spaced apart from the first axis of rotation at a first precise, predetermined distance. The support surface is positioned in a second plane at least substantially parallel to the first plane and spaced apart from the first plane at a second precise, predetermined distance. The rotary table assembly can also include a workpiece positioner fixedly connectable to the table, where the workpiece positioner has at least one support for supporting a workpiece off the table top surface, and the at least one support has at least a second axis of rotation. The rotary table assembly can further include a gearbox for precisely rotating the table.

A feeder for transferring workpieces from one press to another on a press line includes a carrier device with a linkage whose free, load-carrying end executes a horizontal linear movement on both sides of the carrier. The end of the linkage system is secured in an elongate boom whose longitudinal direction coincides with the linear movement. The boom is provided with a holder device appropriate to the workpieces and movable along the boom by an endless belt which, at the ends of the boom, runs over rollers and which, with the lower part, is secured in the holder device and, with the upper part, in the carrier device. The boom is provided with a sliding guide and is supported on the carrier device.

The attachment is intended for use with a machine tool comprising rotary tool means and a rotary spindle for driving said tool means and comprises a shaft adapted to be connected to said spindle for rotation therewith, a rotary bearing carried by said shaft, a pantograph mounted on said bearing for an angular movement relative to said shaft about the axis thereof and adapted to carry said tool means at a distance from said axis, a tracer carried by said pantograph at a distance from said axis, and an angled drive mechanism and operatively connected to said main shaft and adapted to be operatively connected to said tool means when they are carried by said pantograph. Said tool means are adapted to be driven from said spindle through said drive means during an angular movement of said pantograph about said axis.

A table carrying a workpiece being machined, is mounted on a base and has at least two degrees of freedom with respect thereto for an optimum positioning of the workpiece with respect to a cutting tool by way of at least two table orientation mechanisms. For the positive locking of the table in the predetermined position with respect to the cutting tool, provision is made for a device comprising: an intermediate link ''''floating'''' in the base and adapted for a continuous sliding contact with the table surface facing the base in the course of the table orienting, and a means for a positive locking of said intermediate link simultaneously with the table and with the base during the course of cutting.

A milling machine is designed for machining the curved surfaces of propelling screws and comprises a turntable with the screw set on it and a fixed gantry along the horizontal guide of which two carriages move to mount bars capable of vertical movement. The lower end face of each bar gets in contact with a vertical cylindrical insert turnable round its axis. The lower end face of the insert is made inclined to the horizontal plane. An overarm is connected to the lower end face of the insert. The longitudinal axis of the overarm is parallel to the lower end face of the insert. A spindle head with a milling cutter held therein is connected to the overarm coaxially to its longitudinal axis. The spindle head is capable of turning round the longitudinal axis. A milling cutter rotation drive is mounted on the overarm.

The invention features a positioning device comprising a workpiece support platform having a planar upper surface, a plurality of linkages, a linkage support member, means connected to the linkage support member for engaging a rotary tool machine, and means for supporting the platform with the upper surface thereof perpendicular to the axis of rotation of the rotary tool of the machine, each linkage being connected for pivotal motion about a first fixed axis relative to the platform and for pivotal motion about a second fixed axis relative to the linkage support, and the distance between the first and second axes being the same for each linkage.
摘要:
A work-positioning device which enables a workpiece supported thereon to be universally accessible to a working tool. First and second pairs of slide units are slidably mounted on a base of the device, and the slide units of each pair are moved towards and away from each other by threaded screws. A work table, to which a workpiece is secured, has locating holes thereon which cooperate with pivot pins and locking pins on each of the slide units, enabling the workpiece to be held in various positions relative to a working tool. A workpiece, like a cube, may have machining work done on its six faces by the tool without being removed from the device.
