专利说明:

The invention relates to a bezel according to the preamble of claim 1.
PRIOR ART Such devices are known in a variety of forms and designs and are on the market. They are used to machine any workpieces and in particular to grind spindles internally or externally. The present invention relates primarily to the manufacture or machining of spindles, but is not intended to be limited thereto.
Such a grinding method and a corresponding processing machine for wavy workpieces is shown for example in DE 10 2009 013 050 A1. This device essentially consists of a workpiece spindle and a tailstock, the workpiece spindle being movable along first guides. It has a grinding spindle with an internal grinding body, a grinding headstock with a grinding wheel for external grinding, in which case the grinding headstock and the grinding spindle can each be moved in the vertical and horizontal directions via vertical slides and horizontal slides. For external grinding, the workpiece is clamped between the workpiece spindle and the tailstock, for internal grinding along the first guide to the tailstock. There is also a bezel opposite the tailstock.
Object of the present invention is to significantly improve a holder of the workpiece during machining.
Solution to the problem [0005] To achieve the problem, the bezel has a plurality of supports, one of the supports being resiliently mounted.
The present invention relates to a stationary bezel, for example opposite a tailstock. A three-point support is preferably distributed in the 120 ° circle. According to the invention, however, it is provided that, in contrast to the prior art, at least one of the supports is resiliently mounted so that it can yield to a certain imbalance or thermal expansion of the workpiece.
Furthermore, it is ensured that the workpiece, in particular the spindle, is mounted in the steady rest with a force which has been determined precisely beforehand. This is all the more important when it comes to a grinding steady rest with a plain bearing, which generates a considerable amount of heat due to friction.
For example, a pneumatic bearing is preferred, with a corresponding pressure stamp, which presses on the workpiece, is pneumatically pressurized.
Description of the figures [0009] Further advantages, features and details of the invention result from the following description of preferred exemplary embodiments and from the drawing; this shows in
1 shows a front view of a bezel according to the invention;
FIG. 2 shows a top view of the bezel according to FIG. 1;
3 shows a section through the steady rest according to FIG. 1 along line III-III;
4 shows a section through the steady rest according to FIG. 1 along line IV-IV. In some applications it is necessary to support a workpiece 1, which is to be machined, against a tailstock or the like by means of a steady rest 2. In the present exemplary embodiment according to FIG. 1, three supports 3.1, 3.2 and 3.3 are provided, each support 3.1 to 3.3 being arranged on a ring 4. The ring 4 itself consists of two ring shells 5.1 and 5.2, which are connected to one another by a joint 6. In this way, the ring shells 5.1 and 5.2 can be opened to receive the workpiece 1. If the ring shells 5.1 and 5.2 are closed, a releasable fixation is preferably carried out by a quick release device 7.
Each support 3.1 to 3.3 presses with a punch 8.1 to 8.3 radially on the workpiece 1. These stamps 8.1 to 8.3 form slide bearings for the workpiece 1. According to the invention, the two stamps 8.1 and 8.3 are adjustable, but are then designed to be fixable, while the stamp 8.2 is resiliently mounted. A knurled nut 9 is provided for the punch 8.3 in FIG. 4, with which a spindle 10 can be rotated into a guide housing 11. This will
CH 710 298 B1 guided a shaft 12 against the punch 8.3 and this pressed against the workpiece 1. In a desired position, the shaft 12 is then fixed by a locking screw 13.
For the resilient mounting of the punch 8.2 of the support 3.2, a pneumatic device is provided. This has a piston 14 in a guide housing 15, a compressed air connection 16 being provided in front of the piston 14. The piston 14 takes the punch 8.2 with it via a shaft 17. The shaft 17 must be radially secured against rotation by a further locking screw 18, whereby axial mobility must be ensured.
2, the bezel 2 sits on a base plate 19, which in turn is located on a rotary plate 20, which is assigned a scale 21.
