Title: Chucking unit of rotary tool
Inventor: KATAOKA KENZOU
IPC: B23B31/22
Filed: 1984-04-18
Abstract: PURPOSE:To greatly improve the tool chucking ability of a chucking unit by utilizing the torque acting on a rotary tool. CONSTITUTION:A grinding bar T is resiliently supported to be prevented from dropping out due to its dead load by an O ring 23 when inserted into a retainer 20. When compressed air is fed into an air turbine after bringing the grinding bar T in contact with burrs to be ground, a rotary driving shaft 70 is rotated at a high speed in a sleeve, and this torque is transmitted to a chucking member 10 of a chucking mechanism. The chucking member 10 makes a roller 30 strongly press a portion of the tool to be chucked by means of a wedging action to firmly hold the grinding bar T and then to drive it in rotation. The grinding bar T can be easily replaced by stopping the compressed air, rotating it by hand in the direction opposite to the driven rotation, releasing the wedging action of the roller 30, and pulling it out.
