摘要： A tool changing device is described, which is provided with a male portion constrainable to a handler and a female portion constrainable to a tool to be handled and removably fittable on the male portion. Locking means are provided to lock the female portion on the male portion, and their respective actuator comprising an electric motor. The locking means are selectively movable between a locked position of the female portion and an unlocked position. Differently from conventional solutions, in the device according to the present invention advantageously the activation of the locking means is not assigned to the electric motor, on the contrary the latter has the task of only moving the locking means to the unlocked position; an elastic element is provided instead, which continuously applies a force holding the locking means in the locked position. The electric motor intervenes only to allow the female portion to be separated.

摘要： The invention relates to a device for clamping a workpiece holder (3) on a collect chuck (2) that can be fixed to a machine tool, having a plurality of clamping elements distributed around the circumference of the collet chuck (2; 42). Said clamping elements that can be adjusted radially to the axis (4) of the collect chuck from a release to a clamping position can be pressed against a circumferential surface (25) of the workpiece holder (3) positioned relative to the collet chuck (2) in the clamping position. The clamping element are designed as rollers (20) having axes (30) aligned nearly tangentially to the collet chuck circumference. A determinable surface pressure thus results in the clamping position as said rollers (20) mutually contact the workpiece holder (3), a clamping mandrel (10) of the collet chuck (2), and the collect chuck part (11). Said surface pressure is thereby reduced and the collet chuck can also be used in the range of greater tensile forces.
摘要翻译：本发明涉及一种用于将工件夹持器（3）夹紧在收集卡盘（2）上的装置，所述收集卡盘可固定到机床上，所述收集卡盘（2）具有围绕所述夹头卡盘（2; 42）圆周分布的多个夹紧元件。能够径向地相对于收集卡盘的轴线（4）从释放到夹紧位置的所述夹紧元件压靠在相对于夹头卡盘（2）定位的工件保持器（3）的圆周表面（25）上）在夹紧位置。夹紧元件被设计为具有与夹头卡盘圆周几乎切线对准的轴线（30）的滚子（20）。因此，当所述辊（20）相互接触工件保持器（3），夹头夹头（2）的夹紧心轴（10）和收集卡盘部分（11）时，可确定的表面压力导致夹紧位置。因此，所述表面压力减小，并且夹头卡盘也可以在更大张力的范围内使用。

摘要： An expandable mandrel for holding a part has a shank with inclined radial slots slidably engaged by keys. The keys are coordinated by a collar which engages an extension on each key. A platen affixes to the shank of the mandrel to provide a stop that will index the position of a part mounted onto the mandrel. The platen has radial key passages to allow longitudinal movement of the keys in the slots. The platen preferably has resilient indexing nubs to engage the part. Preferably, the position of the platen on the mandrel can be adjusted by a set screw engaging one of several indexing holes or engaging a longitudinal guide track. For machining in a wet environment, the slots can be provided with longitudinal rails and the keys provided with transverse channels to remove liquid from between the keys and the slots.

摘要： The locking ring anvil has a frame assembly and a means for mounting the frame assembly, a pivot assembly is mounted on the frame assembly. A barrel and arbor assembly is mounted on the pivot assembly. The pivot assembly includes means for retaining the barrel and arbor assembly in a fixed position and for rotating the barrel and arbor assembly about a semicircle. The barrel and arbor assembly also include a tapered arbor and a barrel and a means for mounting the barrel about the tapered arbor. The barrel may be rotated about the arbor and moves back and forth on the tapered arbor.

摘要： This disclosure is directed to a chuck system for a machine tool such as a lathe. It incorporates an elongate cylindrical body which terminates in a set of collet fingers having enlargements at the detail end whereby the enlargements define a circular body. The circular body is divided by slots to form collet fingers with enlargements at the ends of the collet fingers. A circumferential groove is formed having a registration shoulder for all of the lock jaw segments. Each lock jaw segment has a protruding tab. The tab is locked by positioning against the face of the groove and is registered against movement by jamming against a transverse post in the groove which shoulders against a conforming notch on the locking tab. A set screw holds the components in fixed location, and release is accomplished by unthreading the set screw.
