- the invention relates to a machine tool with a work spindle, with a provided for attachment to the work spindle base flange as part of a quick-change tooling quick-change system, which further comprises a connectable with the clamping device removable flange.
- Screw the chuck body of a chuck is attached.
- the type of attachment requires that when set by the user change of the chuck high set-up times incurred, so that now in commercial use clamping device quick-change systems are used in which the base flange is connected to the work spindle.
- This base flange is designed such that a releasable connection can be made to one of a plurality of flanges, the alternating flanges each carrying different clamping means.
- the set-up times can be reduced and therefore relatively frequently replace the clamping means with another. After the replacement, however, adjustments must be made to the clamping device currently in use via the machine control in order, for example, to avoid exceeding the maximum actuating force or the maximum rotational speed.
- the invention is therefore based on the object at a

- a quick-change tooling system 1 that in the embodiment shown consists of a fixed to the work spindle 2 of a machine tool not shown itself clamping means 3 as a base flange 4 and a plurality of removable flanges 5, on which different workpiece clamping means 6 are attached ,
- Clamping quick-change system 1 allows quick replacement with the work spindle 2 connected chuck 6, wherein connected in the individual components according to the invention by coupling members 47
- Line sections 45, 46 are arranged, in particular the Machine control of the machine tool in the chuck 6
- Figure 1 a shows the clamping means 3, which is provided for attachment to the work spindle 2 of a machine tool and has a receptacle 7 for the work spindle 2 having clamping means body 8. Furthermore, the clamping means 3 has at least two clamping jaws 9, which can be adjusted radially to the body axis, and a drive ring 10, for the rotation of which in the circumferential direction a drive 11 is provided. In the embodiments illustrated in the drawing, a total of 6 are arranged distributed uniformly over the circumference
- Clamping jaws 9 provided and the drive 1 1 is basically formed by a rotatable about a radial axis drive wheel 12.
- a structure serving for the adjustment of the clamping ring 9 is formed on the outer circumference of the drive ring 10, namely a control cam 14 formed on the outer circumference with control cam 15 serving radially outwardly for adjustment of the clamping jaws 15.
- the structure can also be realized on the inner circumference of the drive ring 10.
- a drive toothing 16 is formed, into which the drive wheel 12 engages, wherein on the drive toothing 16 having side of Drive ring 10 is a return curve 17 is formed in the
- FIGS. 7 and 8 show an embodiment in which an indicator curve 19 is formed on the outer circumference of the drive ring 10
- an indicator pin 20 for indicating the rotational position of the drive ring 20 of the indicator pin is preferably arranged body 8 in a radial bore of the clamping means, so that its position is visually recognizable from the outside; a review of the radial position of the
- Indicator pin 20 is also possible by means of a sensor for acting on the control of the machine tool.
