摘要： A quick-acting clamping device for clamping tools or workpieces in machine tools comprises a piston which is slidable transversely to the clamping direction and which acts on a toggle mechanism which in turn moves a clamping piece. A pressure plate upon which the toggle mechanism acts is displaceable in the clamping direction in a housing which contains the transverse piston. The fluid under pressure which acts on the transverse piston to activate the toggle mechanism also acts directly on the pressure plate to assist in clamping. Because of the assisting force produced by the pressure plate it is possible for the transverse piston to move the members of the toggle mechanism from starting positions in which they lie at large angles to the clamping direction, that is with a big angular displacement from their dead-center position, in which they initially exert only a small force on the clamping piece. Because of this large angular displacement of the members of the toggle mechanism, the toggle mechanism by itself can produce a large linear movement of the clamping piece.
摘要翻译：用于在机床中夹紧工具或工件的快速夹紧装置包括可横向于夹紧方向滑动并且作用在肘节机构上的活塞，该肘节机构又使夹紧件移动。肘节机构作用的压板可在包含横向活塞的壳体中沿夹紧方向移位。作用在横向活塞上以致动肘节机构的压力下的流体也直接作用在压力板上以有助于夹紧。由于压力板所产生的辅助力，横向活塞可能使肘节机构的构件从起始位置移动到与夹紧方向成大角度的位置，即与其死区大的角位移中心位置，其中它们最初仅在夹紧件上施加小的力。由于肘节机构的构件的这种大的角位移，肘节机构本身可以产生夹紧件的大的线性移动。

摘要： A clamping device which is arranged to clamp a workpiece to a table or stand, and which does not obstruct the clamping region of the table or stand, has a fluid pressure-loaded clamping piston slidably mounted in a main housing with toggle levers on either side thereof bearing against oppositely situated saddle bearings at the sides of the housing. The toggle levers are moved by the clamping piston between an inclined position and an extended position and load a clamping or pulling anchor which is mounted on the housing. The clamping or pulling anchor is pivotally mounted on a clamping lever so that it can swing through a maximum of 180.degree. from a clamping position into a release position in which it is well clear of the workpiece. The anchor is fitted onto a bearing pin, which is disposed in an end, which projects from the housing, of the clamping lever which is pivotally mounted in the housing. The opposite end of the clamping lever rests against one of the saddle bearings of the toggle levers and is guided slidably in the housing.

摘要： In a force amplifier, supporting members extend between a pressure plate and a countersupport plate. At each plate the supporting members bear against end bolts and intermediate the plates the support members bear against joint bolts. A spreader bolt extends through the countersupport plate and has a spreader head located between the joint bolts. The surfaces of the spreader bolt contacting the joint bolts are concavely shaped.

摘要： A clamping device, for use for example for clamping a tool or workpiece in position in a machine tool comprises a clamping anchor to which a clamping force is applied by a hydraulically operated cylinder. The device also includes a screw operated compensating or back-up unit which acts on the piston of the hydraulic cylinder. The compensating unit is driven by the same hydraulic system as the hydraulic cylinder and when the piston has been moved hydraulically to apply the clamping force to the anchor, a screw component of the compensating unit moves into engagement with the piston to lock the piston in position and maintain the clamping force even if the hydraulic pressure on the piston is then released.

摘要： The spring washer (14) is held concentrically between a pressure washer (15) and a bearing ring (16) around a spindle (13) between upper and lower parts (4',4") of a housing. The axial force for tightening is transmitted from a movable armature through the spindle to a tensioning unit (12) and an axial bearing (17). The flattening of the spring washer beyond a predetermined amt. actuates a limit switch (18) to immobilise the motor. USE/ADVANTAGE - Esp. with very heavy tools of large presses, the tightening process is terminated at a target value of tension which is easily monitored during operations.

摘要： A tie bolt (13) is fastened in the end of a leadscrew (9) which passes through an axially fixed nut (7) and can be raised or lowered by a motor (12) driving onto the nut. The leadscrew can also be turned through 90 deg. by a second motor drive (11) to bring the tie bolt head (14) into engagement with an aperture in the press ram. The tie bolt head and tie bolt shank are in the form of a single-acting hydraulic cylinder and piston rod. The upper working chamber (18) is connected to a two-way valve (23) which in turn is connected to an accumulator. ADVANTAGE - Greater ease and convenience of unlocking ram.
