摘要： The slide 14 carries a support 18 for a plurality of tools, which is secured to a sleeve 34 rotatable and axially slidable on a body 38. The slide 14 carries a series of hydrostatic bearings 36, 39 and 87 to guide rotatably the sleeve 34 and axially the body 38. The sleeve 34 is antulrly tied to the body 38 through a normally closed front clutch 42, 43, which is opened by axially displacing the sleeve 34 with respect to the body 38, through a hydraulic device 44, 47. A reversible electric motor 52 is operated for rotating the sleeve 34 to select the tool, and may be numerically controlled for continuously displacing the tool during a working operation.

摘要： A precision machining system for machining a workpiece into a desired surface with two tool driving units. A first drive unit moves the tool along at least two axes to shape the workpiece similar to a desired surface. A second drive unit moves the tool along one of the axes in a very finely controlled manner. A measuring unit measures the tool position with an accuracy higher than that to which the first drive unit can respond. A signal producing unit is responsive to the measuring unit for producing a control signal for controlling the operation of the second drive unit while the first drive unit is operating.

The bearing body further has loaded ball guide grooves respectively formed in the inner walls of ridges which face the corresponding recesses, and non-loaded ball guide bores formed through the ridges in parallel to the corresponding loaded ball guide grooves and with a necessary distance therefrom. End plates are respectively mounted to end portions of the bearing body. Each end plate is provided in the inner surface thereof with a ball guiding U-groove for providing communication between the non-loaded ball guide bores and the corresponding loaded ball guide grooves. The cross-linear slide bearing unit further includes track rails slidably fitted in the recesses, respectively, of the bearing body through balls. Each track rail is provided in the lateral outer walls thereof with loaded ball raceway grooves which are parallel to the corresponding loaded ball guide grooves.

摘要： The present invention is directed to a mechanism by which small deviations in slideway straightness and roll of a precision machining apparatus may be compensated for. The mechanism of the present invention comprises a fixture support disposed between the slideway carriage and the tool or workpiece fixture and provided with a hinge-like coupling between the carriage and the fixture support so as to allow for the minute and precise displacement of the fixture support in a direction normal to the direction of the slide path so as to readily compensate for slight deviations in the straightness and roll of the slide path.

摘要： A pallet positioner is used to locate a pair of pallets in selected positions on the turntable of a concrete pipe making machine. The pallet positioner has a frame supported for vertical movement on upright supports below the turntable. A hydraulic cylinder connected to the frame operates to move the frame up and down. A pallet guide and positioning structure connected to the frame is moved up through holes in the turntable to support pallets above the turntable. The form assembly having two jackets is placed over the raised pallets and locked into the bell sections of the jackets. The form assembly has lock structures which hold the pallets in the bell section of the jackets. The frame and pallet guide and positioning structure is then lowered away from the turntable. The form assembly is moved by the turntable to locate the jackets in vertical alignment with two packerheads. A gear box mounted on a cross head is connected to downwardly directed packerhead shafts operable to rotate the packerheads. The cross head is movably mounted on an upright frame and is lowered to the bottom area of the jackets adjacent the pallets before concrete is discharged into the jackets by separately controlled conveyors. A dual bell packer is moved into engagement with the pallets to rotate and vibrate the pallets to form the bell sections of the concrete pipes. The packerheads are simultaneously rotated and elevated in the jackets, as concrete is discharged into the jackets, to simultaneously build up the cylindrical walls of the pair of concrete pipes.

摘要： A lathe to simultaneously machine two or more die molds in chucks of a headstock at one end of a bed used to support a saddle which is moved along a bed by a feed screw parallel to the rotational axes of the chucks. A drive in the headstock also rotates a master mold about a horizontal axis at a laterally-disposal location from the die molds. A probe provides a signal corresponding to the internal surface contour in the master mold to move cutting bars which always extend in a generally-parallel relation with the rotational axes of the chucks during machining of the die molds. A first swivel is carried by a cross slide upon the saddle. The first swivel is adjustable about a vertical axis to provide a desired angle between the direction of attack by the cutting bars and the horizontal axes of rotation by the chucks. A linear displacement assembly is supported by the first swivel and includes a movable member which is reciprocated by a piston and cylinder assembly for displacing the cutter bars according to the output signal from the tracer probe. A second swivel is supported by the movable member of the linear displacement members to angularly position tool support bars so that the bars extend in a generally-parallel relation with the horizontal axes. The tracer probe carried by a follower bar is supported by a swivel frame which is supported by the second swivel so that the follower bar extends in a generally-parallel relation with the cutter bars.

摘要： A lathe is designed to accommodate a variety of machining operations, and provide automatic feed and accuracy of alignment at a minimum of cost. The preferred form of the machine is adapted to function either as bench lathe with its own speedreducer, or in conjunction with a base machine providing support and power at variable rotational speeds.
