摘要： A power operated wrench for acuating the drawbars on machine tools, such as vertical spindle milling machines, which permits the operator to move a single handle, and after release of a safety interlock move a pneumatic wrench into position to engage the drawbar nut and either tighten or loosen the drawbar depending on the direction of motion of the operator handle. The mechanical operation permits the operator to rotate the operator handle in the same direction as would be done if the drawbar was being manually tightened or loosened, in order to tighten or loosen the drawbar under power. The safety interlock prevents movement of the power motor into engagement with the drawbar until the machine has been shut off.
摘要翻译：用于引导机床上的拉杆的电动扳手，例如垂直主轴铣床，其允许操作者移动单个手柄，并且在释放安全联锁之后，将气动扳手移动到位置以接合拉杆螺母并且收紧或者根据操作手柄的运动方向松开拉杆。机械操作允许操作者沿着相同的方向旋转操作手柄，就像在拉杆被手动拧紧或松开时所做的那样，以便在动力下拧紧或松开牵引杆。安全联锁防止动力马达与牵引杆接合，直到机器被关闭。

摘要： A chuck especially for a machine tool that operates in a universal manner as a two, three or four jaw chuck. The chuck (10) comprises four jaws (25) arranged in diametrically opposed pairs on the front face (12) of the chuck (10). The chuck (10) including drive pinions (36, 37) that drive a scroll (39, 239) that co-axially carries a differential gear train including a pair of differential gears (50, 51) one driving one pair of jaws (25) and the other driving the other pair whereby the differential gear train apportions the drive between the pair of jaws so that one pair may move independently of the other pair.

摘要： A chuck attachable to a drill powered by a reversible motor, is adapted for use in driving lag rods into wooden supports and has an axial bore extending therethrough which is partly threaded from one end to receive the machine-threaded end of a lag rod. A plug member is screwed into the threaded end of the bore of the chuck and has a formation enabling it to be so turned as to be seated at the inner end of the threads for engagement by the extremity of the machine threaded end of the lag rod. In order to so reduce the frictional engagement between the plug member and the extremity of the lag rod, the area of the engaged extremities is limited thus to ensure the release of the lag rod when the motor is reversed after the lag rod has been driven into the support to a desired extent.

摘要： It has been hitherto customary durig machining of workpiece, such a grinding of gear wheels, to slip a roller cage over the gear wheel. The chuck jaws of the chuck then hold the workpiece by way of the rollers in a roller cage. The time concuming operation is made superfluous by a holding ring which is mounted in the chuck. The holding ring has openings near the chuck jaws, and also has in this region fixedly installed roller-cage-type segments. Input guides at the holding ring allow quick, safe and secure exchange of the workpieces.

摘要： In an arrangement for coupling a false jaw to a master jaw of a chuck, wherein a positive locking is effected by a radial displacement, the master jaw is provided with an extension having a stop surface and a projection. The false jaw has a recess for receiving the extension and a relief shoulder and is guided in the direction of rotation. Due to this arrangement, the false jaw is well supported and highly stable, so that strong forces can be transmitted, and a high repetitive accuracy in chucking is obtained.

摘要： A drill chuck for a hammer drill apparatus or the like having a plurality of clamp jaws advanceable to and retractable from a chuck drill axis so as to be able to grasp and hold a drill, wherein each of the clamp jaws is advanced into and retracted from a chuck opening in the chuck in a feed channel directed toward, and preferably perpendicular to, the chuck drill axis and further oriented so that the clamp jaws engage and hold the drill in the chuck opening when advanced in the channels, each of the feed channels being conformed so that each of the clamp jaws fits movably, but sufficiently tightly, therein so that drilling dirt does not penetrate between the clamp jaws and the surfaces of the feed channels, and the drill chuck is provided with a plurality of open cleaning passages connecting the interior wall of the chuck opening adjacent a mouth of one of the feed channels to the outside through the chuck. Additionally so that limited axial play and efficient hammer action may be obtained, the clamping surfaces of the chuck jaws are each provided with a row of projections parallel to the drill chuck axis.

摘要： A tool clamping device used with a machine tool is provided for clamping a tool on a tool spindle. In a bore of the tool spindle, there is axially movably received a guide bush which is formed with a recess for permitting steel balls to retract toward radial outward directions. A retainer for holding the steel balls is received in a bore of the guide bush for axial movement relative thereto. The guide bush is connected to a draw bar which is axially movable in the bore of the tool spindle and which is spring-biased toward a rearward direction of the tool spindle. Thus, when the draw bar is spring-drawn toward the rear end of the spindle, the steel balls are restrained from radial outward movements through engagements with the internal surface of the guide bush thereby to clamp the pull stud of the tool. However, when the draw bar is moved toward the front end of the spindle against the biasing force of the spring, the steel balls are retracted into the recess of the guide bush thereby to release the pull stud of the tool.
摘要翻译：提供与机床一起使用的工具夹紧装置，用于将工具夹紧在工具主轴上。在工具主轴的孔中，轴向可移动地容纳有引导衬套，该引导衬套形成有用于允许钢球朝向径向向外的方向缩回的凹部。用于保持钢珠的保持器容纳在导向衬套的孔中，用于相对于其轴向移动。引导衬套连接到可在工具主轴的孔中可轴向移动并且朝向工具主轴的向后方向被弹簧偏压的拉杆。因此，当拉杆朝向主轴的后端弹簧拉动时，钢球通过与导套的内表面的接合而被限制在径向向外的运动中，从而夹紧工具的拉杆。然而，当拉杆克服弹簧的偏压力朝向主轴的前端移动时，钢球缩回到导套的凹槽中，从而释放工具的拉头。

摘要： An automatic draw bar for removably securing machine tools carried by a tool holder within the spindle of a milling machine or the like, in which the tool holder is formed with an internally threaded bore. The spindle is provided with an elongated bore having a recess at its end to receive the shank of the tool holder. A hollow draw bar is slidably carried within the spindle and is exteriorly threaded at one end with a thread engagable with the tool holder interior thread. An elongated draw bar expander slidably carried within the draw bar and responsive to a source of linear power is adapted to couple the threads on the draw bar and tool holder to draw the tool holder into frictional engagement with the spindle upon activation of the power source.
