摘要： A machine tool having a rotatable machine tool spindle for performing drilling and tapping operations. The spindle has limited axial movement relative to the spindle carrier. Fluid pressure means may be operated to displace the spindle in opposite directions for a predetermined position in the spindle carrier and to apply a force yieldably opposing return of the spindle to the predetermined position. The position of the spindle in its carrier is sensed by control means and the spindle carrier is translatable toward or away from the workpiece in response to the direction of displacement of the spindle from its predetermined position. The spindle is displaced forwardly to effect translation of the spindle carrier and spindle to engage a tool with a workpiece and the return of the spindle to the predetermined position upon the engagement of the tool with the workpiece is utilized to initiate control means for automatically controlling the depth of drilling or tapping as measured from the surface of the workpiece and the return of the spindle to an automatic repeat position or to a home position. The spindle is allowed to float while a tapping tool is in engagement with the workpiece and the feed and return of the spindle carrier is controlled during this period by sensing the position of the spindle in the carrier. During drilling the spindle is locked against axial movement relative to the carrier while the tool is in engagement with the workpiece. The locking means is engageable over the range of axial movement of the spindle relative to the carrier to locate the spindle in a predetermined position relative to the carrier.
摘要翻译：一种具有用于执行钻孔和攻丝操作的可旋转机床主轴的机床。主轴相对于主轴托架具有有限的轴向运动。可以操作流体压力装置以使主轴在相反方向上移动到主轴托架中的预定位置，并施加可屈曲地相反的主轴返回到预定位置的力。主轴在其载体中的位置由控制装置感测，并且主轴托架能够响应于主轴从其预定位置的移动方向朝向或远离工件平移。主轴向前移位以实现主轴托架和主轴的平移，以使工具与工件接合，并且在工具与工件的接合时将主轴返回到预定位置用于启动控制装置，用于自动控制从工件表面测量的钻孔或攻丝深度以及主轴返回到自动重复位置或原位置。当攻丝工具与工件接合时，允许主轴浮动，并且在此期间通过感测主轴在载体中的位置来控制主轴托架的进给和返回。在钻孔期间，当工具与工件接合时，主轴被锁定以抵抗相对于托架的轴向运动。锁定装置可以在主轴相对于托架的轴向运动的范围内接合，以将主轴定位在相对于托架的预定位置。

摘要： A control system for a direct-current servo motor drive amplifier which changes the magnitude of the voltage supplied to the amplifier according to the magnitude of the input signal to the amplifier in order to reduce the power loss in the amplifier and thereby permit the use of lower rated components, for example, transistors. The amplifier input signal is supplied to a plurality of operational amplifiers in a level-detecting circuit that operates to selectively connect a plurality of voltage sources to supply the voltage requirements of the drive amplifier in accordance with the magnitude of the input signal. An embodiment of the voltage-switching circuit employing controlled rectifiers and an embodiment employing transistors are disclosed.

摘要： An apparatus for determining the position of one part, such as a movable operating head of a machine tool, relative to a reference position on another part, such as a base of the machine tool, includes an improved scale assembly on one part of the machine tool. This scale assembly includes a plurality of identical scale segments which are spaced apart and independently adjusted relative to a standard, such as a laser interferometer, so that any error in the positioning of one scale segment does not affect the other scale segments. A relatively coarse scale is associated with the plurality of identical scale segments to provide a unique representation for each of the identical scale segments. Suitable control circuitry switches between leading and lagging signal generators in a reading assembly mounted on the other part of the machine tool to avoid activating signal generators at transitions between scale segments.

摘要： AN IMPROVED TURRET MECHANISM FOR SELECTIVELY ROTATING AN INDEXIBLE TURRET TO BRING TOOLS HELD THEREBY INTO AN OPERATIVE RELATION WITH A WORKPIECE INCLUDES CURVIC COUPLING FOR LOCKING THE TURRET IN A SELECTED ANGULAR POSITION. A CENTRAL SHAFT MEMBER OPERATIVELY ASSOCCIATED WITH THE TURRET AND HAVING A CAM FOLLOWER AFFIXED THERETO WHICH IS ROTATABLE WITH THE CENTRAL SHAFT, AND A CAM TRACK IN WHICH THE CAM FOLLOWER ROTATES AND WHICH EFFECTS AXIAL MOVEMENT OF THE CENTRAL SHAFT AND THE TURRET ASSOCIATED THEREWITH UPON MOVEMENT OF THE CAM FOLLOWER THROUGH THE CAM TRACK. ROTATION OF THE CENTRAL SHAFT IN IN ONE DIRECTION RAISES THE TURRET TO DISENGAGE THE TEETH OF THE CURVIC COUPLING AND INDEXES THE TURRET. ROTATION OF THE CENTRAL SHAFT IN THE OPPOSITE DIRECTION LOWERS THE TURRET AND ANGAGES THE TEETH OF THE CURVIC COUPLING TO THEREBY LOCK THE TURRET IN A SELECTED POSITION. THE INDEXING MECHANISM ALSO INCLUDED STOP MEANS WHICH NORMALLY LIMIT THE ROTATION OF THE TURRET SO THAT THE TURRET MAY ONLY BE ROTATED TO ITS NEXT OPERATIVE POSITION. THIS CONSTRUCTION ENABLES THE TURRET TO BE RAPIDLY AND EFFICIENTLY UNLOCKED, AUTOMATICALLY INDEXED TO A NEW POSITION, AND THEN LOCKED IN THE NEW POSITION WITH A SUFFICIENT FORCE SO THAT INADVERTENT ROTATION OF THE TURRET OUT OF THE NEW POSITION WILL NOT OCCUR DUE TO VIBRATION OF THE TURRET.

摘要： A trepanning tool that is characterized by the provision of a cylindrical cutting head projecting coextensively from a shank that has an axis of rotation. Consumable cutting elements are releasably attached to the cutting head in axially projecting relationship therewith and these elements are also releasably secured against movement radially, circumferentially and axially of the cutting head. The tool also has a relieved wall section in the cutting head extending axially and circumferentially so as to provide a means of chip egress during the cutting operation.

摘要： Controlled power supply system for connection to an AC source and having two oppositely connected silicon controlled rectifiers (SCRs) for conducting current in opposite directions to an electrical load. Two sawtooth waves of opposite slope and phasedisplaced by 180* are combined with an error signal to determine the firing times of the SCRs. The error signal represents the difference between a desired value and the actual value of a load variable, such as rotational speed when the load is an electric motor. Each sawtooth wave has a period equal to the AC source signal and during each cycle has a straight line slope for 270*, is abruptly reset to a reference level, and remains at the reference level for the remaining 90* of the cycle.

摘要： A method of and apparatus for guiding a group of slivers through a drafting unit while progressively reducing the width of the group in its course through successive drafting zones of the unit to ensure that the fibers along the longitudinal side edges of adjacent slivers are intermingled throughout the width of the web to obviate the formation of feather-edge selvages on the individual slivers and to ensure homogeneity and substantial uniformity of the fibers throughout the width of the web being drafted. Also, evener roll means is provided for varying the rate of feed of the respective slivers entering the unit in accordance with, and to compensate for, variations in density of the slivers.

摘要： AN IMPROVED COILER ASSEMBLY FOR COILING SLIVER IN A STATIONARY CONTAINER INCLUDES A COILER HEAD WHICH IS SIMULTANEOUSLY ROTATED BY A FIRST DRIVE TRAIN ABOUT AN AXIS WHICH IS OFFSET FROM A CENTRAL AXIS OF THE CONTAINER AND BY A SECOND DRIVE TRAIN ABOUT THE CENTER AXIS OF THE CONTAINER. ROTATION OF THE COILER HEAD ABOUT THE FIRST AXIS RESULTS IN THE FORMATION OF A COIL OF SILVER IN THE CONTAINER WHILE ROTATION ABOUT THE CENTRAL AXIS OF THE CONTAINER DISPLACES LOOPS OF THE COIL OF SILVER RELATIVE TO EACH OTHER. AN ECCENTRIC IS PROVIDED FOR ADJUSTING THE POSITION OF THE COILER HEAD RELATIVE TO THE CENTRAL AXIS OF THE CONTAINER TO ENABLE SILVER OF DIFFERENT THICKNESSES TO BE COILED IN THE SAME RELATIONSHIP WITH A WALL OF THE CONTAINER. A TRANSMISSION MEANS FOR CONNECTING THE DRIVE TRAINS TO A SOURCE OF POWER INCLUDES A PLURALITY OF PAIRS OF GEARS SO THAT THE GEAR RATIO OF THE TRANSMISSION MEANS AND THE RATE AT WHICH THE COILER HEAD IS ROTATED AROUND THE CENTRAL AXIS OF THE CONTAINER CAN BE ADJUSTED TO VARY THE EXTENT TO WHICH THE LOOPS OF SILVER ARE DISPLACED RELATIVE TO EACH OTHER.
