Description: |
| Abstract:
A hydraulic type chuck or holder for receiving and driving a lobed shank of a tool or other operated part, the chuck having a sleeve which has a straight passage of lobed configuration and which is so formed as to have annularly spaced thick wall portions alternating with annularly spaced thinner deformable portions which can be expanded into gripping and centering engagement with the driven shank when fluid pressure is applied to fluid pressure chambers defined in part by the outer side of the shell.
Claim:
An expanding hydraulic type holder for an operated part comprising, a body having a central passage, a generally tubular shell having curved portions interfitting said passage, means for securing the shell to the body, said shell having a passage of irregular sectional contour, adapted to releasably receive and rotatably drive a noncircular contoured spindle of an operated part, said shell having annularly spaced thick wall portions alternating with annularly spaced thinner wall portions which are deformable by fluid pressure to grip the spindle of an operated part, and means for applying fluid pressure between the shell and the body to deform said shell. |
