摘要： A servo system for the rotary spindle of a machine tool in which the spindle is driven by a drive motor through a gear train having shiftable gears for changing the rate of rotation of the spindle. The transducer for the servo system is mounted directly on the motor drive shaft in order to avoid all backlash between the resolver and the drive motor. However, the transducer is arranged to regulate the angular orientation of the spindle and must therefore be maintained in synchronism with the spindle. This is accomplished by arranging the shiftable gears so that when they are moving into engagement with a new gear, engagement with the previously engaged gear is maintained until initial engagement with the new gear is achieved. Further shifting movement into full engagement with the new gear operates to release the previously engaged gear. Thus, during the initial engagement with the new gear, the shiftable gear is momentarily in engagement with both gears. As a result, there can be no relative movement between the gears and synchronism with the transducer is thereby maintained.
摘要翻译： 一种用于机床的旋转主轴的伺服系统，其中主轴由驱动电动机通过具有用于改变主轴的转动速率的可移动齿轮的齿轮系驱动。 伺服系统的传感器直接安装在电机驱动轴上，以避免旋转变压器和驱动电机之间的所有间隙。 然而，传感器被布置成调节主轴的角度定向，因此必须与主轴保持同步。 这是通过布置可移动齿轮来实现的，使得当它们移动到与新齿轮接合时，保持与先前啮合的齿轮的啮合，直到实现与新齿轮的初始啮合。 进一步的换档运动与新齿轮的完全啮合操作以释放先前啮合的齿轮。 因此，在与新齿轮的初始接合期间，可换档齿轮暂时与两个齿轮接合。 结果，齿轮之间不存在相对运动，从而保持与换能器的同步。

摘要： A high speed toolholder for driving a small high speed cutting tool from the large slow speed spindle of a machining center comprises a housing having a retention pin extending from side end thereof. An input shaft, dimensioned to be received in the machining center spindle, is rotatably journaled into the toolholder housing parallel to the retention pin. Rotatably journaled into the opposite side of the housing so as to be coaxial with the input shaft is an output shaft whose distal end has a tapered bore therein dimensioned to receive the shank of a high speed cutting tool. Within the housing, each of the input and output shaft carry a separate one of a pair of sheaves which are each lined by a V-belt to a separate one of a pair of sheave members on a step sheave rotatably journaled in the housing parallel to the input and output shaft. When the housing is positioned adjacent to the spindle so that the input shaft firmly seats into the spindle and the retention pin seats in a bore the machine tool spindlehead, rotational energy is transmitted from the spindle to the output shaft to rotatably drive the cutting tool therein at a speed several times greater than the spindle speed.

摘要： The tool change mechanism includes a tool storage magazine having a plurality of tool storage sockets disposed in two concentric circles. A tool transfer arm is mounted within the inner circle of sockets. The transfer arm may be rotated and extended or retracted and moved toward and away from the magazine for extracting a previously used tool from a ready socket and inserting such tool into a designated socket of the magazine. In like manner, the transfer arm will operate to extract a selected tool from any one of the sockets in the magazine and transfer it to the ready socket. The latter is mounted on a carrier which also supports a tool change arm. The carrier is pivotable between a loading position and a tool change position. When the carrier is in the loading position, the ready socket is located at the magazine where it is accessible to the tool transfer arm for extracting previously used tools from the ready socket and inserting new tools into it. On the other hand, when the carrier is in the tool change position it is located adjacent to the spindle in position to enable the tool change arm to interchange tools between the ready socket and the spindle.

摘要： This invention relates to a greatly simplified workpiece changer mechanism in combination with a simplified tool storage and changing mechanism for a machine tool. To accomplish this, a rotatable work carrying spindle is adapted to support a workpiece for selective rectilinear movement relative to an associated rotary cutting tool, and to support the same workpiece for selective rotational movement relative to a rectilinearly movable cutting tool carried by the same spindle. The work receiving spindle is mounted in spaced apart relationship to a storage support adapted to releasably carry a workpiece for selective interchange with a workpiece carried by the work spindle. To effect a selective interchange of workpieces between the work spindle and the storage support, a work transfer arm is pivotally supported between the work spindle and the work support. At its opposite ends, the work transfer arm is provided with oppositely extending openings respectively adapted to receive work support rings of like size and configuration. The arrangement is such that the transfer arm pivots 90.degree. in one direction for moving the oppositely disposed openings presented thereby into clamping engagement with the workpieces respectively carried by the work spindle and the storage member. Automatic clamping means respectively associated with the work receiving openings are disposed to be actuated into clamped engagement with the workpieces for retaining them in predetermined angularly clamped positions during the interchange. Next, the work spindle and support member are retracted from engagement with the respective work supports, and the transfer arm rotated through another 180.degree. for respectively realigning the work supports in interchanged position with the work spindle and the support member respectively. The latter are moved forward into clamping reengagement with the now interchanged work supports. The transfer arm clamping means are then released and the transfer arm pivotally moved 90.degree. in the opposite direction to return the transfer arm to its central parked position. To accelerate controlled movement of the work transfer arm, a velocity control system is provided in combination with automatic clamping means for retaining work support rings in clamped engagement within the oppositely disposed openings provided in the transfer member.
