Definitions
- the present invention relates to a device for machining workpieces, in particular of peripheral areas of disk-shaped workpieces, such as circular saw blades, with a clamping device for fixing the workpiece to be machined in machining positions, a machining device for machining the workpiece and a feed device for moving the workpiece between a first machining position and at least one further machining position, the machining device for machining the workpiece being displaceable relative to the workpiece defined in the machining position by means of a single-axis arrangement or an axially controllable multi-axis arrangement.
- WO 93/00194 shows a device for processing circular saw blades, in which the processing device is designed to process circular saw blades fixed on the circumferential areas by means of the clamping device, in particular grinding individual saw teeth.
- the processing device is designed with a grinding wheel arrangement which can be positioned with the multi-axis arrangement relative to the circular saw blade to be processed.
- the circular saw blade to be machined is fixed in such a position by means of the clamping device that a particular saw tooth can be machined by the grinding wheel arrangement.
- the circular saw blade is moved by means of a feed device in such a way that the next sawtooth to be machined is positioned in a corresponding machining position.
- the feed device is formed separately, i. H. with a separately driven feed pawl, the feed movement of which is realized by means of a separate drive device.
- the feed device further comprising a contact element which can be brought into contact with the workpiece, the contact element being coupled to the single-axis or multi-axis arrangement and for moving the workpiece between the first machining position and the at least one further machining position can be controlled by means of the feed device, the single-axis arrangement or at least one axis of the multi-axis arrangement.
- the contact element is moved over the single or multi-axis arrangement provided for positioning the processing device, i. H. shifted over the main machine axes.
- the feed movement can be achieved by correspondingly controlling the single or multi-axis arrangement of the machining device without the feed device having to be designed with an additional drive which has to be controlled with the additional control effort involved.
- the machining device has a machining head with a rotatably drivable grinding wheel arrangement or an eroding tool arrangement.
- the contact element is attached to the processing head. The contact element is preferably located on the machining head in a position in which it does not interfere with the grinding wheel arrangement or the eroding tool arrangement.
- one embodiment of the invention provides that the machining head is attached to a linear guide slide of the multi-axis arrangement.
- the machining head together with the contact element and the machining device can be pivoted about a pivot axis relative to one of the linear guide carriages.
- the contact element is fixed on the processing head.
- the contact element can also be displaceable relative to the machining head according to the invention. This can be achieved, for example, in that the contact element is resiliently articulated on the processing head. With this measure it can be ensured that the contact element yields and dodges during the interaction with the workpiece to be machined when a certain force threshold value is exceeded, in order to avoid damage to the workpiece to be machined.
- Another advantage of this exemplary embodiment is that the contact element only has to be displaced linearly in order to be moved from one tooth gap to another tooth gap.
- the predetermined force threshold is exceeded and the contact element yields. If it reaches the area of the next tooth gap, it moves into it under the spring preload. This considerably simplifies the feed movement for finding tooth gaps.
- a further development of the invention provides that the contact element relative to the machining head between a release position in which it releases the workpiece to be machined and a contact position in which it is in contact with the Workpiece can be brought into contact or is in contact with it, can be displaced, preferably can be pivoted about a pivot axis.
- the invention can, when the workpiece to be machined has to be shifted between two machining positions via the feed device, the contact element from the
- the contact element is attached to a swivel arm which can be displaced relative to the linear guide carriage about the swivel axis and which is between an active position in which the contact element is in the release position and a passive position in which the contact element is in the contact position, is displaceable.
- the pivot axis is essentially orthogonal or essentially parallel to a planar wheel surface of the workpiece.

- an inventive device for grinding circular saw blades is generally designated 10.
- This comprises a machine base 12 on which a multi-axis arrangement 14 is attached.
- the multi-axis arrangement 14 comprises a linear guide 16, on which a linear guide slide 18 is guided along the axis X running perpendicular to the drawing plane according to FIG. 1.
- the linear guide carriage 18 carries a further linear guide 20 on which a further linear guide carriage 22 is linearly guided along an axis Y.

- a machining head 30 is attached to the linear guide slide 28 and has a grinding wheel arrangement 32 that can be driven around the axis of rotation A at its end lying at the bottom in FIG. 1.
- the grinding wheel arrangement 32 is used to machine cutting teeth 34 of a circular saw blade 36.
- the circular saw blade 36 to be machined is attached to a clamping device 38, which is supported on the machine base 12, and can be fixed thereon.
- the circular saw blade 36 is processed tooth by tooth.
- a reference point of a cutting tooth 34 of the circular saw blade 36 to be machined preferably the front edge of the tooth face of the cutting tooth 34 of the circular saw blade 36 to be machined, is brought to a predetermined point in a predetermined position within the device 10, whereupon the circular saw blade 36 is fixed by means of the clamping device 38.

- a feed device 40 is provided, which is attached to the machining head 30.
- the feed device 40 comprises a bearing arm 42 which is fastened to the machining head 42 and at its free end one with respect to the 2 has an inclined end face 46 on which a peg-shaped contact element 44 - also called a feed pawl - is attached.
- the feed device 40 works. As soon as the cutting tooth 34 ⁇ is finished, the circular saw blade 36 is released by the clamping device 38. Then the machining head 30 is displaced via the multi-axis arrangement 14 in such a way that the free end of the contact element 44 lies against the tooth face of the cutting tooth 34 2 . As soon as the contact element 44 and the cutting tooth 34 2 are in contact with one another, the machining head 30 is displaced via the multi-axis arrangement 14 in such a way that the free end of the contact element 44 moves along the movement path 48 and thereby the circular saw blade 36 about its central axis B according to arrow Q emotional.
- the trajectory 48 has a circular segment-shaped course corresponding to the circular circumferential line of the circular saw blade 36. It can thereby be achieved that none during the feed movement along the movement path 48
- the cutting tooth 34 2 is correspondingly moved from its position shown in FIG. 2 to the position of the cutting tooth 34 1
- Fig. 2 moves, so that the end of the feed movement of the bearing arm in its position indicated at 42 v and the cutting tooth 34 2 in the for
- Processing intended target position is located with respect to the geometric point P.
- the circular saw blade 36 is then fixed again via the clamping device 38, so that the cutting tooth 34 2 can be processed.
- the procedure explained above is used analogously for all other cutting teeth to be machined.
- FIG. 2 also shows the return stroke movement 50 carried out by the contact element 44 after the cutting tooth to be machined has been positioned in the desired position intended for machining with respect to the geometric point P.
- the arrangement can be seen in plan view in FIG. 3.
- a summary of FIGS. 2 and 3 shows that the contact element 44 projects obliquely into the plane of extent of the circular saw blade 36.
- FIGS. 4 and 5 show a second embodiment of the invention in representations corresponding to FIGS. 2 and 3.

- the bearing arm 142 can be pivoted about a pivot axis C relative to a coupling piece 154 against a spring force.
- the coupling piece 154 is fixedly attached to the processing head 130.
- a certain force threshold value which is predetermined by the spring force, is exceeded, the bearing arm 142 pivots. This can prevent an force-intensive interaction between the contact element in the event of an unintentional jamming of the circular saw blade 136 or an undesired collision of the contact element 144 and circular saw blade 136 144 and comes into contact with this cutting tooth, by which the circular saw blade 136 is damaged or the function of one of these components is impaired.
- such an arrangement also serves to find a tooth gap between two successive cutting teeth, in which the contact element 144 is first applied to a side surface of the circular saw blade 136 under spring prestress and is subsequently moved until it is in one
- the device according to the second embodiment functions as described above with reference to the first embodiment according to FIGS. 1 to 3.
- FIGS. 6 and 7 show a third embodiment of the invention in representations corresponding to FIGS. 2 and 3.

- FIGS. 6 and 7 differs from the embodiment according to FIGS. 4 and 5 only in the orientation of the pivot axis C. While the pivot axis C in the second embodiment according to FIG. 4 runs parallel to the plane of the drawing, the pivot axis C in the third embodiment runs in Figure 6 perpendicular to the plane of the drawing. Ultimately, however, the same advantageous effects can be achieved as in the arrangement according to FIGS. 4 and 5, namely a resilient yielding of the bearing arm 242 carrying the contact element 244 in the event of a force-intensive interaction or collision between the contact element 244 and the cutting tooth just contacted and also a slight one Finding tooth gaps without the risk of damaging the circular saw blade 236.
