摘要： A work holding device comprises an annular cylinder 14, an annular piston 15 movable with respect to the cylinder within the cylinder in an axial direction by application of fluid pressure, and a jaw drive device 28, 29, 30, 31 projecting from the cylinder 14 for applying radial movement to a work holding jaw 12, 13. The piston and/or the cylinder co-operates with the jaw drive device within the cylinder such that axial movement of the piston with respect to the cylinder causes radial movement of the jaw drive device. Since the translation of axial to radial movement takes place effectively within the cylinder, it is possible to reduce the axial length of the work holding device as compared to known work holding devices in which translational movement occurs outside the cylinder.

摘要： A chuck comprises a body (10) rotatable about an axis (11) and at least one jaw (12) movable in a radial direction to clamp a workpiece in the chuck. At least one operating lever (14) is mounted on the body (10) and the, or each, lever is operable to move a jaw (12) radially. The, or each, lever is also movable axially with respect to the chuck body (10), to disengage from the associated jaw (12), enabling the associated jaw (12) to be removed simply and quickly from the chuck body (10) by movement in the radial direction.
摘要翻译：卡盘包括可围绕轴线（11）旋转的主体（10）和可沿径向移动的至少一个钳口（12），以将工件夹紧在卡盘中。至少一个操作杆（14）安装在主体（10）上，并且每个杠杆或每个杠杆可操作以径向地移动卡爪（12）。所述杠杆或每个杠杆也可相对于卡盘主体（10）轴向移动，从而与相关联的卡爪（12）脱离接合，使相关联的卡爪（12）能够从卡盘主体（10）快速地移除，通过径向运动。
