Definitions
- the invention relates to a clamping nut with an eccentrically incorporated pull-out tab for releasing the collet from the collet holder.
- the eccentric arrangement of the pull-out tab creates an imbalance which causes vibrations at high speeds.
- the centrifugal forces caused by this unbalance increase with the square of the speed and can reach considerable values. This can result in poorer machining results or even damage to the machine tool.
- the invention has for its object to achieve the compensation of the unbalance without the disadvantages mentioned.
- Figure 1 is an axial sectional view of a collet assembly.
- Figure 2 is an axial and two radial sectional views of an embodiment of a clamping nut.
- Fig. 3 is an axial and two radial sectional views of a further embodiment of a clamping nut and
- Fig. 4 is an axial and a radial sectional view of another embodiment of a clamping nut.
- a collet 2 is inserted into a collet holder 1 with a receiving cone 10.
- the collet 2 has a 30 ° cone 6 on its end face by means of which the collet is pressed centrally into the receiving cone 10 of the collet holder 1 by a clamping nut 3 with a corresponding inner cone.
- the latter has a thread 7 on its outer wall, onto which the clamping nut 3 is screwed.
- the surface of the clamping nut 3 has a coating or another surface treatment which reduces the friction on the thread and on the 30 ° cone and protects against corrosion.
- the clamping nut 3 has a pull-out tab 4 for releasing the collet from the receiving cone 10.
- This pull-out tab which engages in a groove 8 running behind the cone 6 of the collet, is usually, as shown in section AA of FIG. 2, by a circular, eccentrically arranged material removal.
- the pull-out tab has the shape of an eccentrically arranged oval and is dimensioned in such a way that the collet snaps into the clamping nut, and is designed such that its function also guarantees a clamping range of 1 mm is. With this alternative form, the necessary unbalance compensation can be kept smaller.
- the oval shape of the pull-out tab also has the advantage that the collet snaps into place during assembly and does not fall out of the clamping nut, as was the case with the conventional design.
- the unbalance compensation 5 consists in removing material with a tool, the contour of which is indicated in the sections B-B of FIGS. 2 and 3 by the dashed circles 9.
- FIG. 4 Another variant of the unbalance compensation is shown in FIG. 4. Instead of the material removal according to FIGS. 2 and 3, axially parallel bores 5 are made in the material behind the pull-out tab 4 in this form.
- the clamping nuts according to the invention have the advantage that the outer contour is not disturbed by compensating bores or milling. Due to the unbalance compensation integrated in the production process, a large part of the Balancing costs can be saved. In addition, the corrosion protection layer is not damaged by subsequent material removal. Pre-balancing can remove up to 90% of the unbalance during production. If a particularly good balancing quality is required, subsequent fine balancing is possible with much less effort.
