Abstract
Collet chucks (20) comprise at least two tensioning segments (21). Adjacent tensioning segments are connected to each other by means of elastic spacer elements (30). The tensioning segments (21) have back-cuts (22), whilst the spacer elements have correspondingly formed sections (36). A positive fit of the formed sections in the back-cuts of the tensioning segments (21) is thus possible.
Claims15
Spacer element for the positive connection of two adjacent clamping segments (21) of a collet chuck (20), with shaped sections (36) formed on facing sides of a connecting segment (32), the spacer element (30) being made from elastomeric material, characterized in that the shaped sections (36) in each case have at least one recess for the introduction of in each case one widening element (40), particularly an expanding mandrel.
Spacer element according to one of the preceding claims, characterized in that the spacer element (30) is cross-sectionally bone-shaped, the thickened end regions (31) forming the shaped sections (36), the web between the shaped sections (36) forming the connecting piece (32), each thickened end region (31) having a centrally positioned bore, which is elliptical, particularly elongated hole-shaped or circular and which axially traverses the end region and on the inside thereof is located a tubular, axially slotted intermediate piece (34).
Collet chuck, particularly for chucking workpieces, with at least two clamping segments (20), in which:
- adjacent clamping segments are interconnected by elastic spacer elements (30),
- undercuts (22) are formed on the clamping segments,
- the spacer elements (30) have shaped sections for positive engagement in the undercuts of the clamping segments,
- characterized in that a widening element is provided and is insertable in the vicinity of the undercuts (22) and the widening element produces a frictional connection between at least one clamping segment (20) and at least one spacer element (30).
