Abstract
A chuck apparatus for the fastening to a working spindle (2) of a tool machine, with a chuck body (8) comprising a receptacle (7) for the working spindle (2), with at least two chuck jaws (9) which can be adjusted radially to the body axis, and with a drive ring (10), for whose rotation taking place in the circumferential direction a drive (11) is provided, comprising a structure is formed on the drive ring (10) on its outer circumference or its inner circumference for each chuck jaw (9) and which serves for its adjusting. The invention furthermore relates to a rapid replacement system (1) with the chuck apparatus (3) as a base flange (4) and with a replacement flange (5).
Claims17
A rapid replacement system comprising:
- a base flange for operably connecting to a working spindle of a tool machine, with a chuck body comprising a receptacle for the working spindle of a tool machine, a clamping apparatus with a chuck body comprising a receptacle for the working spindle, said clamping apparatus having at least two chuck jaws which can be adjusted radially to a body axis, and a drive ring configured for rotation in the circumferential direction by a drive, comprising a structure is formed on said drive ring on its outer circumference or its inner circumference for each chuck jaw and which serves for its adjusting, a replacement flange which can be clamped by said base flange and can be operably connected to a workpiece clamping apparatus, and an air pipe adapter configured to rotate at least to a limited extent about an axis of said working spindle by at least one coupling member, wherein a rotation of said drive ring can be derived by at least one coupling member from a rotation of said drive ring.
A rapid replacement system, comprising:
- a base flange for operably connecting to a working spindle of a tool machine, a chuck apparatus with a chuck body comprising a receptacle for said working spindle, said chuck apparatus having at least two chuck jaws which can be adjusted radially to a body axis, said chuck jaw has an L-shaped base comprising a base shank and a control member is arranged thereon, and a pin receptacle open to a drive ring formed in a second shank into which a contact pin is inserted in said pin receptacle, wherein said drive ring is configured for rotation in the circumferential direction by a drive, and a structure formed on said drive ring on its outer circumference or its inner circumference for each chuck jaw configured for adjusting said drive ring.
A rapid replacement system comprising:
- a base flange for operably connecting to a working spindle of a tool machine, a chuck apparatus with a chuck body comprising a receptacle for said working spindle, said chuck apparatus having at least two chuck jaws which can be adjusted radially to a body axis, said chuck jaw has an L-shaped base comprising a base shank and a control member is arranged thereon, and a pin receptacle open to a drive ring formed in a second shank into which a contact pin (is inserted in said pin receptacle, said contact pin has a plane surface on a side facing said drive ring and said contact pin further comprises a pin foot for operably connecting in said pin receptacle, wherein said drive ring is configured for rotation in the circumferential direction by a drive, and a structure formed on said drive ring on its outer circumference or its inner circumference for each chuck jaw configured for adjusting said drive ring.
