1,124,363. Tool-clamping. SOC. GENEVOISE D'INSTRUMENTS DE PHYSIQUE. 5 Nov., 1965 [4 Dec., 1964], No. 47037/65. Heading B3B. A machine tool comprises a tool-gripping rod 7 biased inwardly from a conical socket in the nose of a spindle and an hydraulic piston actuatable to move the rod to a tool-releasing position. The spindle carries an adaptor socket 14 having an external taper of 29À17 degrees and an internal taper of 5 degrees to receive a tool, or the tool itself seats in the spindle recess 15. In operation, a switch (37) is actuated to cause the rod 7 to project from the spindle to enable the operator to engage a projection 36 on the tool or adaptor in a recess in the end 10 of the rod. The spring 9 then clamps the tool. The tool 38 is clamped with less force since the projection 36 is carried on an extended shank 39. Reference has been directed by the Comptroller to Specification 920,879. |
