Abstract
A clamping chuck having a body (2) with a slidable spindle (7) in a housing (9). The housing is inclined relative to the axis (xx′) of the chuck and exiting through the front face (3), the spindle (7) movement driven by a piston (19) along the chuck axis and the spindle equipped with a groove (15) into which slides a drive section (25) of the piston. An end of the spindle (7) has a notch (17) exiting into the groove (15) such that, when positioning the spindle from the front face (3) of the chuck, allows the spindle (7) to move along the drive section (25) and touch the latter and enable its groove (15) to be positioned facing the drive section (25), such that such that after one rotation of the spindle (7) around its axis (uu′), the groove (15) engages with the drive section (25).
Claims11
A clamping chuck comprising a body accommodating at least one slideably mounted spindle in a housing in the body, said spindle comprising a first end and a second end, said housing being inclined relative to the axis of the chuck and exiting through the front face of the latter, the spindle movement being driven by the movement of a piston along the chuck axis and said spindle being equipped at one end with a groove into which slides a drive section of the piston, the latter and said groove being perpendicular to the axis of said spindle, wherein:
- the second end of the spindle comprises a notch exiting into the groove such that, when positioning the spindle from the front face of the chuck, the notch allows the spindle to move along the drive section and touch the latter and enable the groove to be positioned facing said drive section, such that after rotation of the spindle around the axis of the spindle, the groove engages with the drive section;
- wherein the piston comprises a plate from which the drive section is created and a bottom of the notch has a section taken perpendicular to the axis of the spindle with a complementary shape to that of the plate of the drive section, wherein the plate revolves around an axis of the plate and the bottom of the notch is circular in shape with a radius similar to that of the plate.
A clamping chuck comprising a body accommodating at least one slideably mounted spindle in a housing in the body, said spindle comprising a first end and a second end, said housing being inclined relative to the axis of the chuck and exiting through the front face of the latter, the spindle movement being driven by the movement of a piston along the chuck axis and said spindle being equipped at one end with a groove into which slides a drive section of the piston, the latter and said groove being perpendicular to the axis of said spindle, wherein:
- the second end of the spindle comprises a notch exiting into the groove such that, when positioning the spindle from the front face of the chuck, the notch allows the spindle to move along the drive section and touch the latter and enable the groove to be positioned facing said drive section, such that after rotation of the spindle around the axis of the spindle, the groove engages with the drive section;
- wherein the clamping chuck further comprises means of triggering the rotation of the spindle around the axis of the spindle for balance;
- and
- wherein the means of triggering the rotation of the spindle comprise a retaining element arranged in a housing in the chuck body comprising a base at the bottom of this housing that is elastically pressed, this base extending by a head that fits into the recess.
