Abstract
A clamping device for individual tools has a spindle and a pulling member nnected inside the spindle. The pulling member has a conical clamping and centering element projection from the spindle. A tool holder has an end face with a recess, the recess having at least one conical mantle surface. The conical mantle surface cooperates with the conical clamping and centering element for clamping and centering the tool holder at the spindle.
Claims30
A clamping device for individual tools, said clamping device comprising:
- a spindle;
- a pulling member connected inside said spindle and having a conical clamping and centering element projecting from said spindle;
- and
- a connecting member of a tool having an end face with a recess, said recess having at least one conical mantle surface cooperating with said conical clamping and centering element for clamping and centering the tool at said spindle.
A clamping device for individual tools, said clamping device comprising:
- a spindle;
- a pulling member connected inside said spindle and having a conical clamping and centering element projecting from said spindle;
- a connecting member of a tool having an end face with a recess, said recess having at least one conical mantle surface cooperating with said conical clamping and centering element for clamping and centering the tool at said spindle;
- said conical mantle surface comprised of two conical mantle surface segments arranged on a common imaginary conical mantle surface;
- and
- said recess extending diametrically in said end face and widening toward an outer mantle surface of said connecting member.
A clamping device for individual tools, said clamping device comprising:
- a spindle;
- a pulling member connected inside said spindle and having a conical clamping and centering element projecting from said spindle;
- a connecting member of a tool having an end face with a recess, said recess having at least one conical mantle surface cooperating with said conical clamping and centering element for clamping and centering the tool at said spindle;
- and
- wherein said end face of said connecting member has first projections and an end face of said spindle, said end face of said spindle facing said connecting member, has second projections, said spindle and said connecting member contacting one another with aid first and said second projections.
A clamping device for individual tools, said clamping device comprising:
- a spindle;
- a pulling member connected inside said spindle and having a conical clamping and centering element projecting from said spindle;
- a connecting member of a tool having an end face with a recess, said recess having at least one conical mantle surface cooperating with said conical clamping and centering element for clamping and centering the tool at said spindle;
- and
- wherein said clamping and centering element has a conical clamping surface and compressed air bores opening within said conical clamping surface.
A clamping device for individual tools, said clamping device comprising:
- a spindle;
- a pulling member connected inside said spindle and having a conical clamping and centering element projecting from said spindle;
- a connecting member of a tool having an end face with a recess, said recess having at least one conical mantle surface cooperating with said conical clamping and centering element for clamping and centering the tool at said spindle;
- and
- at least one follower connected to said connecting member and said spindle for connecting said connecting member and said spindle in a rotationally fixed manner in a direction of rotation of said device.
