摘要： A keyless chuck (10; 301) comprises a jaw housing (28; 311) with jaws (32; 333, 335, 337) which are slidably mounted in guideways (40; 319, 321, 323) between a rearward opened position and a forward closed position. A jaw thrust member (34; 345) is coupled to the jaws and is slidably mounted in the jaw housing to apply a thrust force to the jaws and to maintain the jaws in the same relative axial location. A nut (42; 355) is fixed to the jaw housing and has a threaded opening (46; 357) coaxial with the chuck axis (Ax). A threaded spindle (48; 305) is engaged in the nut opening and is movable forwardly to apply clamping force to the jaws and rearwardly to remove clamping force. The jaws may be spring biased forwardly to a closed position (self-centering) and thus not movable responsive to movement of the spindle. A lock mechanism (22, 104, 42; 309) is preferably provided to limit relative rotation between the nut and spindle to prevent the application of excessive clamping force and to limit removal of clamping force.

摘要： A thrust converter has a connection pipe 30 for outputting reciprocating motion of first rotation/reciprocation conversion means 115 and a joint nut 28. The joint nut 28 is interposed between the first rotation/reciprocation conversion means 115 and the connection pipe 30, connected to the first rotation/reciprocation conversion means 115, and coupled to the connection pipe 30 with a screw. The thrust converter is constructed such that connection pipe 30 is driven by a second servo motor 31, thereby setting an arbitrary position where the joint nut 28 and the connection pipe 30 are to be coupled together. As a result, there is obtained a thrust converter which can shorten the axial length of the thrust converter in comparison with a required stroke, which obviates a necessity for operating two motors synchronously when a workpiece is fed to a gripping position or the like, and which facilitates motor control.
摘要翻译：推力转换器具有用于输出第一旋转/往复运动转换装置115和接头螺母28的往复运动的连接管30.接头螺母28介于第一旋转/往复运动转换装置115和连接管30之间，第一旋转/往复运动转换装置115，并且用螺钉联接到连接管30。推力转换器被构造成使得连接管30由第二伺服电动机31驱动，从而设定将接合螺母28和连接管30联接在一起的任意位置。结果，获得了与所需行程相比可以缩短推力转换器的轴向长度的推力转换器，这消除了当工件被馈送到夹持位置等时同步地操作两个电动机的必要性，这有助于电机控制。

摘要： The invention relates to a chuck having a sleeve, a chuck body, a plurality of chuck jaws, an adjusting mechanism configured to adjust relative movement between the chuck jaws and the chuck body, at least one locating member and a pushing mechanism. The locating member is disposed on the chuck body between the adjacent chuck jaws. When the adjusting mechanism drives the chuck jaws to approach to each other relative to the longitudinal axis, the pushing mechanism pushes the locating member to move towards the longitudinal axis. When the adjusting mechanism drives the chuck jaws to move away from each other relative to the longitudinal axis, the pushing mechanism pushes the locating member to move away from the longitudinal axis. Therefore, the operation is more convenient and safer; the aligning effect is precise and reliable, and the pre-tightening force is stable.
