摘要： Hydraulically controlled holding devices for accurately locating and securely locking parts in position during the performance of various manufacturing and testing operations. The holding devices may be in the form of arbors or chucks and each comprises a body having at one end a segmented sleeve. The body contains a closed hydraulic system with a piston for each sleeve segment and an actuating means for the simultaneous operation of all of the segment pistons. Each segment is deformable by its respective piston so that the part will be engaged at the end of the holding device with equal pressure by all of the segments upon proper adjustment of the actuating means.

摘要： A hydraulically controlled holding device for accurately locating and securing locking tools or workpieces in position during the performance of various manufacturing and testing operations. The holding device may be in the form of an arbor or a chuck and comprises a body having a closed hydraulic system therein and a thin-walled sleeve adapted to be pressurized into contact with the tool or workpiece by the application of hydraulic pressure thereon from the closed system. The holding device is characterized by the fact that the thin-walled sleeve is constantly pressurized, in the presence or absence of a tool or workpiece, and requires the action of an outside agency or force to relieve the pressure on the thin-walled sleeve. The holding device may also be provided with indicator means to show whether or not the thin-walled sleeve is properly and adequately pressurized.

摘要： A quick-change top tooling system is provided to accommodate various sized and configurations of workpieces to be chucked. The quick-change top tooling system includes a chuck body, at least one jaw assembly, and at least one workstop assembly. The jaw assembly comprises a master post fixed to a surface of the chuck body and a jaw releasably coupled to the master post. The workstop assembly comprises a workstop base mounted to the surface of the chuck body and a workstop releasably coupled to the workstop base. The at least one jaw and workstop may engage and clamp a workpiece to be chucked to maintain the concentricity and parallelism of the workpiece.
