Problems solved by technology

Especially in the case of high-speed milling machines, this problem has not been solved by current state-of-the-art
[0008] In addition, the disadvantage often arises of unwelcome lateral forces in the clamping phase, which are caused by the clamping ball or other clamping elements

Embodiment Construction

[0043] figure 1 is a possible embodiment of the clamping device 1 of the present invention. The inner chuck 2 is fixedly connected with the outer chuck 3 by means of screws 18 , wherein the inner chuck 2 is arranged concentrically with the outer chuck 3 . The basic body of the inner chuck 2 consists of parts 15 which are fastened together by means of screws 17 . The inner chuck 2 has clamping balls 4 which cooperate with an inner clamping piston 12 and a tensioning spring 5 in a manner known per se. The outer chuck 3 is configured accordingly. The basic body consists of parts 14 which are fastened together by means of screws 16 . It likewise has a clamping ball 6 , an outer clamping piston 13 and a tensioning spring 7 . The two clamping pistons 12 , 13 can be acted upon in a known manner by means of compressed air. Both the inner chuck 2 and the outer chuck 3 have not only an inner x-y reference 8 or an outer x-y reference 9 but also an inner z reference 10 or an outer z ...

Abstract

The invention relates to a clamping device for a tool or a workpiece, comprising at least one chuck and at least one holder for the workpiece or the tool. The holder (19) is provided with a tubular extension (24).

Description

technical field [0001] The invention relates to a tool or workpiece clamping device comprising at least one chuck and at least one holder for the tool or workpiece. [0002] Clamping devices of this type are used for mounting workpieces or tools, wherein a high degree of precision is required when machining the workpiece. Furthermore, precise and repeatable mounting of the workpiece or tool in the x, y and z directions must be guaranteed. Background technique [0003] EP-A-255042 describes a clamping device in which, in order to position the two connecting elements (chuck and holder) exactly relative to each other in the z-direction (which generally coincides with the clamping direction), in one of them There are several struts on the connecting element and the reference planes are designed on their free end faces. A plurality of z reference planes are located on the other connecting element in an arrangement corresponding to the pillar, these z reference planes lie on the...
