Description

The present invention relates to a device for manual adjustment, measurement sen, possibly testing tools for machine tools, especially for Tool or sharpening machines, with a tool holder for that Tool and with a setting and measuring device, the setting and Measuring device optical and electronic components for the detection of the tool has, the optical and electronic components a visual display with egg nem used to set the tool edge coordinate cross and a with the visual display interacting evaluation unit and wherein the Tool holder and the setting and measuring device at least in two coordinates next are movable and adjustable relative to each other. In addition, the present invention a method using the device is carried out.

The setting, measuring and, if necessary, testing of tools serves to provide tools for Processing machines such as machine tools or sharpening machines, CNC Presetting machines optimally. The tool setting during manufacture supply sequence of a CNC machine is avoided for cost reasons, so that a measurement and setting is carried out on a device in question. E.g. a drilling tool must be measured in such a way that during later processing the prescribed drilling depth is observed exactly. The position of the Determine tool tip in relation to the tool holder. The one with the front direction and in particular determined with the setting and measuring device and op Timed coordinates can be used later when using the tool can be read into the tool memory of the CNC machine.

Devices for the manual presetting and measuring of tools in Are discussed in practice and in various brochures, For example, documented in the "bravo" brochure from Zoller. The be from practice Known devices include a tool holder in which the tool is is excited, and an adjusting and measuring device, which with optical and electronic components. The setting and measuring device and the Tool holders can be moved relative to one another in two coordinate planes and adjustable. The optical and electronic components of the known device  include a visual display in the form of a projector with a coordinate system, an observer lens and an evaluation unit.

In handling, the known device is in view of the inter between Qualification of the operator and time expenditure as well as setting accuracy existing correlation disadvantageous. After setting the tool in the factory The tool holder is roughly adjusted by moving the setting and measuring units direction with the projector in the tool area, then the tool is in rotated the coordinate plane to focus the image. Finally the Fine adjustment, adjusting until the tool cutting edge in the koor the projector's cross appears. During these three basic steps What matters is the best approximation to the coordinate system or to realize the sharpest setting of the tool cutting edge. One less qualified operator will need a large number of adjustments, around the setting and measuring device and the tool holder in the correct position to each other and the distance between the tool cutting edge shown and reduce the axes of the coordinate system to zero. The assessment of whether an optimal setting remains in the area of subjective assessment tongue. The reproducibility that can be achieved here is between 0.005 and 0.01 mm.

From the area of automatic setting or measurement of tools gene, in particular from EP 0520 396 A1, is - seen by itself - a device known, which on a camera and a monitor as well as an image processing computer as optical and electronic components of the setting and measuring device falls back. The movement of the setting and measuring device and the tool neck ters in the desired position is automatically realized by motors, whose Tä activity is triggered by pulses from the image processing computer. Given the automatic, motorized adjustment, the problem mentioned at the outset arises with regard to the time required and the setting accuracy depending on the Operator qualifications not. With the automatic device reproducibility can be achieved ± 0.001 mm. The ones quoted in the Document described, in addition to the coordinate system on the monitor  LED indicators appear only for monitoring and signaling the time when the exact measurement results are available. As constructive be the automatic tool setting and -measuring the equipment of the device with motors and the associated Control.

Based on these, different objectives and the devices procedures carried out using the devices - manual adjustment and Measuring on the one hand, automatic setting and measuring on the other - that is Invention, the object of starting a device of the type in question give, which requires a relatively low technical effort, a simple Manageability guaranteed and a short response time and a high measuring Accuracy achieved regardless of operator qualifications. In addition, should a method that can be implemented by means of the device can be specified.

The foregoing object is achieved in terms of the device by the features of claim 1 solved. After that, a device is the one in question Kind designed and developed in such a way that the optical and electronic Components comprise a camera, preferably equipped with a lens, that the evaluation unit is designed as an image processing computer, that the image processing computer cooperates with the camera that the visual display as Monitor is executed and that the monitor in addition to the coordinate cross auxiliary marks that shows the deviations of the tool cutting edge to the coordinates cross display and the setting of the tool holder and / or the setting and Specify measuring device.

According to the invention it was first recognized that the optical and electronic cal components of the known manual device a little technical require design effort and that the optical and electronic components the known automatic device are basically suitable for the manual use to be applied and on the other hand an easy one tion of handling and an increase in the measuring accuracy of the device un depending on the qualification of the operator. Further is recognized  the advantages of the two well-known - manual and automatic - devices and a camera, as an optical and electronic component NEN monitor and an image processing computer to use, on the Moni Tor auxiliary marks appear, according to which the operator when adjusting the Tool or the tool cutting edge by adjusting the setting and Measuring device and / or the tool holder can direct. That way on the one hand, a low technical and constructive effort is guaranteed, and on the other On the one hand, an aid is provided that is independent of each operator by their qualification, the tool or the cutting edge under Orientation to the auxiliary marks quickly and with optimal accuracy in the coordina crosses. By specifying the setting using the auxiliary marks a subjective assessment by the operator is effectively excluded and enables a more precise relative movement. Easy handling of the Device according to the invention, in particular under an ergonomic face point, can also be realized in that the monitor is at seat height as required could be arranged or adjusted to the operator's eye level can. The adjustment to the operator's eye level helps to increase the Measuring accuracy at. The use of a variably arrangeable and adjustable monitor is extremely advantageous compared to a fixed projector.

The optical and elec Use tronic components for testing purposes, for example when already be used tools to be measured in terms of their quality and intensity resharpening by specifying the tool position in the tool holder the sharpening machine is fixed. Except for the work mostly described here Tool cutting can also set different tool effective areas, ver measure and check if necessary, e.g. embossing structures of embossing tools or Tools used to expand workpieces.

The auxiliary marks are expediently processed by the image processing computer created, which evaluates the data coming from the camera in real time, the Deviations of the tool cutting edge from the coordinate system using an Ar work program and sends impulses to the monitor. The Andes  Monitor-forwarded impulses are used to generate the recognition on the monitor Auxiliary marks, which precisely prescribe to the operator, on which How the setting and measuring device is to be moved. By the immediate arrival Show the auxiliary marks and thus the change in distance in real time The process of setting and measuring is enormously simplified for the operator. It is particularly advantageous that solely because of the outgoing from the camera Signals the auxiliary marks on the monitor through the work program of the image processing processing computer can be created. This eliminates the need for additional entries and no controls on the image processing computer are necessary.

According to a very particularly preferred embodiment of the invention The auxiliary marks are designed in such a way that they look like a magnifying glass act and enlarge the adjustment grid. Because of the relatively low resolution the image area of the monitor defined by the coordinate system lung inaccuracies are eliminated by advantageously in the area of Auxiliary marks through the work program of the image processing computer a higher Resolution is generated.

The auxiliary marks are expediently arranged at the edge of the image of the Moni tors, outside the coordinate system, so that no overlap with the Tool cutting edge mapping is done. In both coordinate planes is exactly on shown how far an adjustment still has to be made until the adjustment process in Be train to the coordinate system is completed. The auxiliary stamps could extend on either side of the respective coordinate axis or are through the image processing computer enabled to vary as needed so that everyone Quadrant of the coordinate cross can be surveyed in terms of auxiliary marks.

The auxiliary marks could be in the form of setting bars, which are at least in two coordinate levels the operator when setting the camera or Setting and measuring device and the tool cutting edge or the tool holder support relative to each other. The operator operates while observing the Setting bar manually the setting and measuring device translationally and / or the Tool holder or the tool holder rotatory, but also other  Relative movements between the setting and measuring device and the tool holder could be considered.

In addition to the auxiliary marks, geometric auxiliary lines could be provided, which are particularly advantageous for complicated tool cutting. The geome As an alternative or in addition to point measurement, trical auxiliary lines enable, where the coordinate axes tangential to the outer boundary of the tool cutting edge illustration, also a line measurement, taking straight sections the tool cutting edge mapping coincides with the geometric auxiliary line be brought.

So that the operator now uses the auxiliary marks to provide instructions for actuation the setting and measuring device and the tool holder, for example. the dimension of the auxiliary marks with the progressive setting of the tool reduce cutting in relation to the coordinate system. Furthermore, in one unchangeable frame for each auxiliary stamp a separate arrow or point Miger or the like. Marking should be provided, the position during the setting changed within the frame and indicates an optimal setting by it is aligned with the respective axis of the coordinate system.

With regard to the focusing that takes place before the fine adjustment the tool edge in the image sharpness plane and the corresponding visualization On the monitor, at least one auxiliary mark could have a double function be directed. As long as the focus is not completed, it remains Tool edge surrounded by a colored "blur edge". The selected one Auxiliary mark first illustrates the setting of the tool cutting edge in the Sharpness level and shows the course of reaching the optimal sharpness, wel che only by observing the "blur edge" would only be imprecise. The operator turns the handwheel of the tool holder while observing the changing auxiliary mark or the mark there changing its position long until the end of the setting process is displayed. During the follow up The fine adjustment gives the same auxiliary mark the setting of the tool cutting edge with respect to the x or z value of the other coordinate plane. In addition or  As an alternative to the auxiliary mark, a text overlay could also be used to indicate the reason to focus, for example commands such as "forward", "next", "stop", "back".

A further embodiment of the device according to the invention could go there hend that the auxiliary marks are shown in color. The end of the one setting process could also be indicated, for example, by a color change of the auxiliary stamp. With the color of the setting bar is for the operator besides the changing dimension of the Auxiliary marks or position shift of the separate markings of the auxiliary given a visual stimulus that counteracts eye fatigue.

As essential to the invention, it is further emphasized that the work pro Gram of the image processing computer according to a particularly preferred Ausge staltung of the invention selection and / or combination options with a view on means for setting and measuring the cutting edge. The picture The processing computer provides the operator with point and / or line measurement options with which any tool cutting edge can be measured can. Nevertheless, the automatic device mentioned above already on the Image processing technology, tool IDs are preprogrammed there grammed so that only set within the preprogrammed fund and can be measured. In contrast, with the device according to the invention by using the auxiliary stamps in combination with the ones made available exact selectable point and / or line measurement options and measurement of unknown, complicated tool cutting, which extend, for example, in more than one quadrant of the coordinate system can. To a certain extent, the image processing computer makes the default geometric measuring lines of the operator setting the tool cut plausibly and this leads to an appropriate selection of the measurement options. Will the approximation to the coordinate system and to the auxiliary line s in a tool cutting edge mapping that extends in two quadrants continued, one of the auxiliary lines is usually cut, which then becomes the lines measurement is no longer usable and irrelevant by the image processing computer is recognized.  

For example, from a range of two line measurement options and a point measurement option a line and a point measurement option selected, deactivated or the image processing computer eliminates the geometric guide not selected never. On the one hand, the recognition of which measurement option is sorted out could be carried out by the image processing computer itself or by the operator per time instrument and data transfer to the image processing computer the. The pointer instrument works especially on the monitor with the image processing processing computer together, limits measuring ranges, specifies measuring windows and could be a lightpen, a button, a mouse or a touchscreen.

With regard to a compact construction of the device according to the invention According to one embodiment, the camera, monitor and to execute the image processing computer as a structural unit. This will a space and time saving installation of the optical and electronic components in or on the setting and measuring device. From the point of view of time Saving during the installation is also essential that the connections from the Image processing computer to the monitor on the one hand and to the camera on the other are already pre-assembled in the unit.

A concrete construction of the device according to the invention now provides that To equip the setting and measuring device with a coordinate slide, which Movement or positioning in two directions of a plane (x and z values) enables. Furthermore, the tool holder for storing the tool expediently cut a tool holder and is in the image movable level. A handwheel can be used for this, which is coaxial to the Tool axis is arranged.

As already mentioned, the tool or the cutting edge should at least two coordinate planes can be detected. A coordinate plane could be used for this on the other hand by the radial distance of the tool cutting edge from the tool axis se (x values) and on the other hand by the longitudinal distance between  Tool cutting edge and tool holder must be specified (z values). The other Coordinate plane could define the image sharpness plane.

It is particularly advantageous with regard to the later use of the tool ges in a processing machine when the tool holder in its training corresponds to the tool holder of a processing machine on which the tool is used. The tool holder could have an identical chuck have or be designed as an adapter-type clamping device, which is compatible with the chuck of the processing machine.

To register the set position of the setting and measuring device and of the tool holder relative to each other could be the device according to the invention a digital counter can be assigned, which displays the set measured values. The The set values could be transmitted via a known device assigned measuring system.

So that an exact optical detection of the tool and as accurate as possible Illustration can be achieved, it is advantageous to be spaced from the camera Light source for illuminating the arranged between the camera and light source To provide tool cutting edge. The light source could usefully be the Setting and measuring device must be assigned and is positional relative to the camera xiert. The camera could also be a lens for quality improvement and / or have enlargement of the tool cutting edge receptacle.

The use of a light-emitting diode as a light source has become particularly advantageous recognized. The low power of the LED is sufficient to generate the required through lights out and brings the advantage with it, the device according to the invention less heat up, which in turn has a positive effect on the measurement results.

Furthermore, the above task is accomplished with regard to the method solved the features of claim 22. After that, a procedure of in Speaking type by using the device according to the invention guided by the tool is fixed in the tool holder by the  Setting and measuring device and the tool holder so posi relative to each other be used until the image of the tool edge in the image sharpness plane and is set in the coordinate plane defined by the x and z values and by the process of setting the cutting edge with the help of auxiliary marks displayed on the monitor.

In detail, the process is based on three basic, state of the art known levels - namely rough adjustment, focus, fine adjustment - carried out. During the rough adjustment, the camera is in the range of Tool cutting edge spent. Auxiliary tokens are not playing at this time Role. Only a blurred image appears on the monitor. The Un Sharpness is advantageously achieved by a colored border around the image of the Tool cutting edge illustrated.

After the rough adjustment, the image is turned by rotating the tool holder in focus, with increasing approximation of the image to the coordina cross first, geometric auxiliary lines parallel to straight sections of the Tool cutting edge appear on the monitor. After entering the figure in A defined, closer area to the coordinate cross is created Auxiliary marks on the edge of the monitor showing the change in position of the tool Detect the cutting edge by enlarging it and change its position or dimensions. In Depending on the shape of the cutting edge, this can not only in one but also in several, e.g. two, quadrants of the coordinate cross extend zes. In the latter example, an approximation would only be made to a coordi natenachse come into consideration, but an exact setting is impossible makes. Here they come through the work program of the image processing computer Geometric auxiliary lines created in an advantageous manner for use. Depending on If required, the operator can select and / or combine the measurement options possibilities and of point measurement possibilities by tanging the coordina tenachsen - at the end of the fine adjustment - and / or line measurement options by covering the lines with the geometric auxiliary lines - also at the end of the Fine adjustment - make use of it. At the end of focusing, a Align the auxiliary mark to an axis of the coordinate system and, if necessary, a color  subject to change and / or there could be an acoustic and / or visual command readable on the monitor. The far blurring signal The edge around the image of the tool cutting edge comes after the focus has been set in the absence.

After focusing, there is now a fine adjustment in two directions their coordinate plane, with the image of the tool cutting point with the coordinate axes or linear with the geometric auxiliary lines or punctual with a coordinate axis and linear with a geometric auxiliary line to Dec equality is brought. An auxiliary mark illustrates the distance the tool cutting edge from a reference point of the tool holder (z values) and another auxiliary mark illustrates the distance between the cutting edge from the tool axis, with one of the auxiliary marks performing a double function in the rear has a focus on the focus.

At the end of the fine adjustment, the auxiliary marks are aligned with one axis of the Coordinate cross and may be subject to a color change.

As essential to the invention, it should be emphasized that during the entire setting based on the auxiliary marks, the course of the calculated distance reduction between the cutting edge and the respective axis of the coordinate system and / or the geometric auxiliary lines are displayed and that the operator - after it knows the coordinate system and / or the geometric auxiliary line ter approximates and almost automatically develops a setting and measuring strategy - itself only have to judge by the auxiliary stamps, without any experience with the contractor to have to show the coordinate cross.

The detection of the completion of the focusing and the fine adjustment takes place preferably via the auxiliary stamps. In addition, LED displays could also be featured to be seen. There are no limits to the variety of display options, for example, acoustic indicators would also be considered.  

With regard to further advantageous embodiments of the Ver driving is based on the general description of the device according to the invention referenced, especially since features are explained there that are also relevant to the method are.

There are now several ways to teach the present invention advantageous to design and develop. This is on the one hand on the the claims 1 and 22 subordinate claims, on the other hand to the following explanation of an embodiment of the invention using the Reference drawing. In connection with the explanation of the cited Aus leadership example of the invention with reference to the drawing will generally be preferred refinements and developments of teaching explained. In the drawing show

Fig. 1 shows a device for manually setting, measuring, if necessary testing of tools for machine tools, particularly for tool or grinding machines or the like., With a tool holder for the tool 1 and with an adjusting and measuring appliance 2. The setting and measuring device 2 has opti cal and electronic components for detecting the tool, which comprise a visual display with a serving for setting the tool cutting edge 3 coordinate cross 4 and an interacting with the visual display via an interface 5 evaluation unit. The tool holder 1 and the setting and measuring device 2 can be moved and adjusted relative to one another in two coordinate planes.

According to the invention, the optical and electronic components comprise a camera 6 and an image processing computer 7 as an evaluation unit. The image processing computer 7 interacts with the camera 6 via an interface 8 . The view display is designed as a monitor 9 , which has 4 auxiliary marks 10 , 11 in addition to the coordinate cross. The auxiliary marks are shown here in the idle state, show the deviations of the tool cutting edge 3 from the coordinate cross 4 in the operating state and specify the setting of the tool holder 1 and / or the setting and measuring device 2 .

To create the auxiliary marks 10 , 11 on the monitor 9 , the image processing computer 7 has a work program with which the distance values of the tool cutting edge 3 to the coordinate cross 4 are determined. The values recorded by the camera 6 are forwarded to the image processing computer 7 , so that the distance value determination and the creation of the auxiliary marks 10 , 11 can take place in real time.

To increase the accuracy of measurement, the auxiliary marks 10 , 11 have a higher resolution than the image area defined by the coordinate cross 4 and cause a magnification adjustment in the direction of a magnifying glass. From Figs. 1, 3 and 5 is ersicht Lich that the servo marks 10, 11 to appear on the screen of the monitor 9. In Fig. 1, only a symbolic representation of the auxiliary marks 10 , 11 was chosen. The auxiliary marks 10 , 11 illustrate in FIGS . 3 and 5 two directions of a coordinate plane (x, - and z values). During the focusing, an auxiliary mark here illustrates a second coordinate plane, namely the image sharpness plane, the appearance of this auxiliary mark during the focusing in FIGS . 2 and 4 not yet taking place and therefore not shown.

From Figs. 1, 3 and 5 It is also apparent that the servo marks 10, 11 are in the form of adjustment bar. Figs. 2, 4 and 5 show that in addition to the ken Hilfsmar 10, 11 auxiliary geometrical lines 22, 23, 24 are provided, with only the auxiliary geometrical line 24 contributes to realization of a line measurement.

In the exemplary embodiment presented here, each auxiliary mark 10 , 11 has a position-changing triangular or arrow-shaped marking 25 within its unalterable frame. If the image of the tool cutting edge 3 is not in register with the coordinate system 4 ( FIG. 3) or - as shown in FIG. 5 - with an axis of the coordinate system 4 and a geometric auxiliary line 24 , the marking 25 is not in alignment with the respective coordinate axis , but in the neighboring area of the auxiliary mark 10 , 11 . FIGS. 3 and 5 show an optimum setting, with one marking 25 of the servo marks 10, 11 is aligned with the respective axis of the coordinate. 4

One of the two auxiliary marks 10 , 11 has a double function and successively specifies the setting of the tool cutting edge in the image sharpness level (not shown here) and the setting of the tool cutting edge with respect to the x or z value of the other coordinate level, such as shown in Figs. 3 and 5.

The work program of the image processing computer 7 provides selection and / or combination options for setting and measuring the tool cutting edge 3 , in the form of point and / or line measurement options.

In FIGS. 2 and 3, a first cutting edge 3 of the coordinate system 4 extends in a single quadrant. Geometric auxiliary lines 22 are provided , which run through the coordinate origin and largely parallel to straight sections of the image of the tool cutting edge 3 . The approach of the first tool cutting edge 3 to the coordinate cross leads to the intersection of the geometric auxiliary lines 22 and their deactivation, which is illustrated in FIG. 3. A two-point measurement is carried out, with a point-like congruence of the mapping to the coordinate axes being established and the two points not being identified in FIG. 3.

FIGS. 4 and 5 refer to a second cutting edge 3 which extends in two quadrants of the coordinate system 4. Geometric auxiliary lines 23 , 24 are created which, due to the origin of the coordinates and largely parallel to straight-line sections of the image of the tool cutting edge 3, are used. Without a further approximation of the second tool cutting edge 3 to the coordinate cross 4 , it can be seen that only a point measurement on a coordinate axis is possible and that the geometric auxiliary line 23 in the section shown in dashed lines is already overlapped and eliminated for a line measurement and thus eliminated can be, as illustrated in Fig. 5. In this second tool cutting edge, a line and a point measurement option are selected from the range of two line measurement options and one point measurement option, the point contacting the coordinate axis z and the line contacting the geometric auxiliary line 24 not being specified.

The specific construction of the device shown in FIG. 1 shows a coordinate slide 12 with an upper and a lower slide 13 , 14th The coordinate slide 12 is a component of the setting and measuring device 2 and can be adjusted in two directions of one plane via the lower slide 14 and the upper slide 13 . On the upper slide 13 of the coordinate slide 12 , an arm 15 projects to which the camera 6 is attached.

The coordinate slide 12 is arranged on a device bed 16 , which has guides (not shown here) for the lower slide 14 and is covered by a bellows 17 which extends from the lower slide 14 on both sides and comes into contact with adjacent components.

The tool holder 1 is movably mounted in a receiving housing 18 , which in turn is mounted on a base part, not specified. The base part could be designed as a slide, but in this exemplary embodiment is designed as a support component for the receiving housing 18 which is fixedly arranged on the device bed 16 . The tool holder 1 together with the tool cutting edge 3 can be rotated into the image sharpness plane about the tool axis A via a handwheel 19 .

Furthermore, a digital counter 20 is provided, which displays the set measurement values in the respective coordinate plane. In particular, the two directions of a coordinate plane of the coordinate system 4 are taken into account, where one direction is defined by the radial distance of the cutting edge 3 from the tool axis A (x values) and the other direction by the longitudinal distance between the cutting edge 3 and the tool holder 1 ( z values) is defined.

Finally, a light source 21 is arranged at the lower end of the upper slide 13 of the coordinate slide 12 , exactly opposite the camera 6 , the lens of which is oriented vertically downward. The light source 21 is used to illuminate the tool cutting edge 3 extending between the camera 6 and the light source 21 and is designed here as a light-emitting diode.

The process sequence using the device according to the invention comprises the following steps in this embodiment:

• - Set the tool in the tool holder 1
• - Moving the coordinate slide 12 into the area of the tool cutting edge 3 (rough setting)
• - Image of the cutting edge on the monitor 9
• - Generation of the auxiliary lines 22 , 23 , 24 through the work program of the image processing computer 7th
• - Focusing the tool edge in the image sharpness plane by turning the handwheel 19 and with sufficient approximation to the coordinate cross 4 - display of the auxiliary marks 10 , 11 , the unspecified, dotted "blur edge" shown gradually by reducing the distance to represent the tool edge 3 , specifically to for congruence with the image of the tool cutting edge and thus for the completion of the focusing, disappears (focusing)
• - Move the coordinate slide 12 (length distance adjustment of the tool cutting edge 3 to a reference point of the tool holder 1 - z values) and (distance adjustment of the tool cutting edge 3 to the tool axis A - x values) while observing the auxiliary marks 10 , 11 until the image of the tool cutting edge 3 has a reduced distance to the two axes of the coordinate system 4 on the monitor 9 ( FIG. 3) or until the image of the tool cutting edge 3 has a reduced distance to an axis of the coordinate system 4 on the monitor 9 and to the auxiliary line 24 has ( Fig. 5) (fine adjustment)
