摘要： A clamping chuck having a body (2) with a slidable spindle (7) in a housing (9). The housing is inclined relative to the axis (xx′) of the chuck and exiting through the front face (3), the spindle (7) movement driven by a piston (19) along the chuck axis and the spindle equipped with a groove (15) into which slides a drive section (25) of the piston. An end of the spindle (7) has a notch (17) exiting into the groove (15) such that, when positioning the spindle from the front face (3) of the chuck, allows the spindle (7) to move along the drive section (25) and touch the latter and enable its groove (15) to be positioned facing the drive section (25), such that such that after one rotation of the spindle (7) around its axis (uu′), the groove (15) engages with the drive section (25).

摘要： A power chuck includes a housing in which there is arranged a drive unit having a traction guide means moveable in the direction of a clamping axis. There, and there are arranged two pairs of mutually diametrically opposite base jaws. The base jaws are guided radially, in the housing substantially perpendicularly to the clamping axis, and the drive unit is adapted to convert the movement of the traction guide means into the movement of the base jaws. According to the invention, it is proposed that the drive unit for each base jaw has a slider which is in engagement with the base jaw and which is moveable with a movement component on a circular path about the clamping axis.

摘要： A test-specimen holder for gripping test specimens to perform material tests in the form of compressive and tensile tests has two grabs coaxially aligned relative to each other and capable of gripping the test specimen. The grabs have angled faces on sides facing away from the test specimen gripped between them. Respective hydraulic gripping cylinders are connected to the grabs for shifting same axially and a wedge can engage the angled faces of both grabs. A fluid-operated synchronization cylinder is connected to the wedge for moving the wedge perpendicular to the axis of the grabs into and out of engagement with the angled faces of the grabs. A fluid reservoir is connected through a 4/2 directional control valve with the gripping cylinders for actuating same. An adjustable first pressure-limiting valve and a check valve connected parallel thereto are connected between the 4/2 valve and the synchronization cylinder.

摘要： A chuck assembly which can chuck thin and brittle workpieces that differ widely in size with high accuracy and reliability without warping them. The chuck assembly includes a tubular chuck body having three first cylinders and a plurality of second cylinders arranged along a circumference in a plane perpendicular to the axis of the chuck body at equal angular intervals. The cylinders have pistons adapted to protrude under oil pressure. The three first cylinders are also arranged at equal angular intervals. The chuck assembly further includes a pressure-biasing means for applying, independently of the oil pressure, pressure to the pistons of the first cylinders against a workpiece, so that the piston are less likely to be retracted by the reaction force from the workpiece. That is, this chuck assembly has a self-centering function.

摘要翻译： 一种卡盘组件，其可以夹紧具有高精度和可靠性的尺寸不同的薄而脆的工件，而不会使它们翘曲。 卡盘组件包括具有三个第一气缸和多个第二气缸的管状卡盘体，多个第二气缸以相等的角度间隔沿垂直于卡盘体的轴线的平面沿圆周布置。 气缸具有适于在油压下突出的活塞。 三个第一气缸也以相等的角度间隔布置。 卡盘组件还包括压力偏置装置，用于独立于油压，将压力施加到第一气缸的活塞抵靠工件，使得活塞不太可能通过来自工件的反作用力而缩回。 也就是说，该卡盘组件具有自定心功能。
