DEVICE FOR THE, IN PARTICULARLY AUTOMATED, PROVISION OF A COMPLETE TOOL

Description

[0001] Device for, in particular automated, provision of a complete tool. The invention relates to a device for, in particular automated, provision of a complete tool according to the preamble of claim 1, a system for, in particular automated, provision of a complete tool with the shrinking and measuring station according to claim 1. 12as well as a method for operating the system according to claim 14. For machine tools operating at high speeds or with special precision requirements, particularly drilling, milling, or turning machines, the use of shrink-fit chucks is widespread, as these offer particularly high concentricity and highly reliable torque transmission between the tool holder and the tool. Such tool holders have a central receiving opening whose diameter is slightly smaller than the outer diameter of the tool to be held. To insert the tool into the tool holder, the holder is heated, for example, using an inductive heating device or a heating blower, until the receiving opening has expanded sufficiently to allow the tool to be inserted.As the tool holder cools, possibly with the aid of a cooling device, it shrinks and clamps the tool securely and reliably on all sides. To remove the tool, the tool holder is reheated until the tool can be pulled out of the holder opening.

[0002] Furthermore, it is common practice to measure a complete tool, consisting of the tool holder and the shrunk-in tool, before coupling it to a machine tool (e.g., a CNC machining center) using a measuring or presetting device, and to use the determined dimensions to optimize workpiece machining. In particular, the length of the complete tool, the diameter, and the cutting edge profile of the clamped tool are measured. Such a measuring device typically includes a rotary spindle, driven by a drive unit, with a holding device for a tool holder or the complete tool. The rotary spindle rotates the complete tool axially during the measurement process.

[0003] From DE 102 49 072 A1, a method for securing a tool in a tool chuck is known, in which the actual position of the tool, particularly in the direction of its longitudinal axis, is first determined by measurement. The tool is then inserted into the tool chuck, positioned there based on the determined actual position, and finally shrunk in. After shrinking, the actual position of the tool within the tool chuck is determined. During the shrinking process and the determination of the tool's actual position, the tool chuck is held on a CNC-controlled tool holding spindle that is rotatable about a rotary axis. Furthermore, the connection between the tool holder and the tool, as well as the measurement of the complete tool, are largely automated. The tool holder and the tool are moved by means of a tool chuck changer and a tool gripper.

[0004] However, such shrink-fitting and measuring processes on a rotary spindle, especially with a high number of shrink-fitting and measuring operations in a short period, result in a relatively high heat input into the rotary spindle. This leads to thermal expansion of the rotary spindle and thus to a reduction in measuring accuracy. Furthermore, the use of a tool chuck changer for moving the tool holder and a separate tool gripper for moving the tool is complex.

[0005] US patent 2010 / 051610 A1 discloses a device on which the preamble of claim 1 is based.

[0006] The object of the invention is to provide a device for the, in particular automated, provision of a complete tool consisting of a tool holder and a tool, with which complete tools can be provided simply and effectively with high repeatability. A further object of the invention is to provide a device for the, in particular automated, provision of a complete tool consisting of a tool holder and a tool, which has a particularly simple, effective and flexible design.

[0007] These tasks are solved by the features of the independent claims. Preferred embodiments are disclosed in the dependent claims.

[0008] The present invention is defined by the accompanying claim 1. According to the invention, a cooling device associated with the rotary spindle is provided, by means of which the rotary spindle can be air-cooled.

[0009] This enables the provision of complete tools with high repeatability and precision, as cooling the turning spindle counteracts its heating. This reduces the thermal expansion of the turning spindle and effectively increases the measuring accuracy of the measuring device. In particular, a higher number of complete tools can be provided within a defined period, since it is no longer necessary to allow the turning spindle to cool down before a subsequent measuring operation.

[0010] According to the invention, the cooling device is formed by a cooling element associated with the rotary spindle, in particular annular and / or disc-shaped, by means of which the rotary spindle can be air-cooled. Thus, effective cooling of the rotary spindle can be achieved with a simple design. In particular, such a cooling element can also be retrofitted to a rotary spindle with minimal effort. Preferably, the cooling element is made of a material with high thermal conductivity, for example, aluminum.

[0011] Advantageously, the cooling element can surround a spindle element of the rotary spindle and / or an adapter element of the rotary spindle, which is detachably connected to the spindle element and includes the holding device, in a ring-shaped manner. It is preferred if the cooling element surrounds a holding section of the rotary spindle, which includes the holding device, in a ring-shaped manner. Heat transfer from a heated complete tool to the rotary spindle occurs at this holding section, so that such an arrangement of the cooling element counteracts heating of the rotary spindle particularly effectively.

[0012] For effective cooling of the rotary spindle, the annular cooling element can be in contact with the rotary spindle via an inner circumferential wall, particularly in a planar configuration. Alternatively or additionally, the cooling element can also be in contact with the rotary spindle via at least one end wall, particularly in a planar configuration.

[0013] According to the invention, the cooling element has an inner region, in particular annular and / or sleeve-shaped, and several cooling fins projecting outwards from the inner region to achieve a simple and effective design. The cooling fins, viewed from above, are designed to have an arcuate or, in some sections, a straight profile. Advantageously, the holding device of the rotary spindle can be configured to accommodate a machine tool interface, such as a tool holder. Specifically, the holding device of the rotary spindle can, for example, have an SK interface (steep taper interface), an HSK interface (hollow taper interface), or a PSK interface (polygonal taper interface).

[0014] For effective measurement of a complete tool, the optical measuring device can include at least one image acquisition device, in particular a camera, for capturing images and / or videos of a complete tool mounted on the spindle. Advantageously, the measuring device can be connected to a screen and / or a data transmission device for transmitting the measured dimensions of the complete tool as data, particularly wirelessly, to an RFID chip. Data transmission can also be carried out, for example, via Bluetooth, QR / Data Matrix, or barcodes.

[0015] In a specific embodiment, the heating device can include at least one coil element, in particular one that can be mounted on a tool holder and / or is ring-shaped, for heating a shrink-fit chuck of a tool holder. A shrink-fit chuck of a tool holder can be heated effectively and quickly by means of such a coil element.

[0016] In a further preferred embodiment, at least one cooling pot, particularly cooled with coolant, can be provided for cooling a complete tool, wherein a complete tool, particularly in an upside-down orientation, can be arranged partially or completely in an interior of the cooling pot and, in particular with a shrink-fit chuck section of a tool holder of the complete tool, can be brought into contact, in particular with a flat surface, with a cooled inner wall of the cooling pot. A measured complete tool can be cooled effectively and quickly in such a cooling pot, which is separate from the turning spindle and in particular not mounted on the turning spindle.

[0017] For the simultaneous cooling of several measured complete tools, several spaced-apart and / or series-arranged cooling pots can be provided. Advantageously, at least one cooling pot can be fixed by means of at least one connecting element, in particular by means of at least one connecting screw.

[0018] According to claim 8, a device for the, in particular automated, provision of a complete tool consisting of a tool holder and a tool, in particular a milling tool, is further proposed, comprising a controllable motion device, in particular a controllable robot arm, for picking up and moving an object, wherein the motion device has a gripper for picking up a tool holder as an object, in particular at a gripper groove of the tool holder. According to the invention, a tool, in particular a rod-shaped one, can also be grasped and / or picked up by means of the gripper.

[0019] Using such a gripper enables a particularly simple, effective, and flexible provision of complete tools, since both tool holders and tools can now be gripped or picked up using a single gripper. For example, automated provisioning or manufacturing of a complete tool can be achieved using a single gripper.

[0020] Preferably, the movement device is designed such that both the position of the gripper can be changed by translations along three vertical axes (x, y, z) and the orientation of the gripper can be changed by rotations around three vertical axes.

[0021] In a preferred embodiment, the gripper is designed in multiple parts, wherein a first and a second gripper part of the gripper each have a tool-holding gripping contour, in particular an arc-shaped one, for receiving a tool holder and a tool-holding contour for receiving a tool, wherein the gripper parts are held on a controllable actuator of the gripper by means of which the distance between the gripper parts can be adjusted, and by reducing the distance between the gripper parts, at least one object can be clamped. This results in a simple and reliable gripper design.

[0022] Advantageously, the tool holder gripping contour and the tool gripping contour of the respective gripper part can be spaced apart from each other. For a simpler manufacturing design, the first and second gripper parts can be mirror images of each other and / or be formed from identical components, particularly plate-shaped ones.

[0023] Furthermore, a system for the, in particular automated, provision of a complete tool consisting of a tool holder and a tool, especially a milling tool, is also claimed using the device according to the invention. It is provided that the system includes a balancing station for checking the balance quality of a complete tool and / or for balancing a complete tool.

[0024] Furthermore, a method for operating the plant according to the invention is also claimed.

[0025] The advantages resulting from the inventive system and the inventive method are identical to the advantages of the inventive devices already acknowledged, so that these will not be repeated here.

[0026] The invention and its advantageous embodiments and / or further developments, as well as their advantages, are explained in more detail below using drawings as examples only. They show:

[0027] Fig. 1, a top view, shows a system for providing complete tools consisting of tool holders and tools; Fig. 2, a perspective view, shows a shrink-fit and measuring station of the system; Fig. 3, a perspective view, shows a cooling device of the shrink-fit and measuring station; Fig. 4, a perspective view, shows an adapter element of the shrink-fit and measuring station; Fig. 5, a top view, shows an annular cooling element of the adapter element; Fig. 6, a sectional view along the sectioning plane AA from Fig. 4 ; and Fig. 7 shows a perspective view of a gripper of a robot arm of the system.

[0028] In Fig. 1Figure 1 shows a system 1 according to the invention for the automated provision and / or production of complete tools 3 consisting of tool holders 5 and tools 7. The system 1 comprises a mobile tool cart 9, which is loaded with several tool holders 5 and several tools 7, here by way of example designed as milling tools. The tool cart 9 is arranged near a controllable motion device, here by way of example designed as a robot arm 11, by means of which the tool holders 5 and the tools 7 can be moved within the system 1. The tool cart 9 is located within the gripping range of a gripper 13 of the robot arm 11.

[0029] As an alternative to the tool trolley 9, the system 1 could, for example, also have a high-bay rack. Furthermore, the feed could also be provided, for example, via a chain magazine or wheel magazine for tool holders 5. Feeding via an endless conveyor belt would also be possible.

[0030] The robot arm 11 is designed in such a way that the position of the gripper 13 can be changed by translations along three vertical axes (x, y, z) and the orientation or alignment of the gripper 13 can be changed by rotations around three vertical axes.

[0031] In Fig. 7 The gripper 13 is shown in an enlarged view. Both the tool holders 5 and the tools 7 can be picked up using the gripper 13. According to Fig. 7The gripper 13 is designed in multiple parts, comprising a first gripper part 15 and a second gripper part 17. Each gripper part 15, 17 has a tool holder gripping contour 19, formed by a recess (here, for example, an arc-shaped one), for gripping a tool holder 5, and a tool gripping contour 21, also formed by a recess, for gripping a tool 7. The gripper parts 15, 17 are held on a controllable actuator 23 of the gripper 13 (here, for example, pneumatically operated), by means of which the distance between the gripper parts 15, 17 can be adjusted. By reducing the distance between the gripper parts 15, 17, the tool holders 5 and the tools 7 can be clamped between the gripper parts 15, 17 and thus held.

[0032] To grip a tool holder 5, each gripper part 15, 17 also has an inwardly projecting, ring-segment-shaped web 25, with which the respective gripper part 15, 17 engages in a circumferential gripper groove 27 ( Fig. 3 ) the respective tool holder 5 can engage.

[0033] As in Fig. 7As further shown, the gripper 13 also has a sensor 29. Sensor 29 can be used to determine whether a complete tool 3 or a tool holder 5 is located near the gripper 13. Here, sensor 29 is represented by an ultrasonic sensor. The gripper 13 also has sensors 31 and 33. Sensor 31 is assigned to the tool holder grip contour 19 of a gripper part, while sensor 33 is assigned to the tool grip contour 21 of a gripper part. Sensor 33 can determine whether a tool 7 is currently clamped or held in the gripper 13. Sensor 31 can determine whether a tool holder 5 is currently clamped in the gripper 13. Here, sensors 31 and 33 are represented by inductive sensors.In addition, each of the pin-shaped sensors 31, 33 is arranged in a recess of the gripper part 15 and held in the recess by means of a clamping screw 35, 37.

[0034] According to Fig. 7Here, each gripper part 15, 17 is formed by two interconnected plate bodies 39, 41. The plate bodies 39, 41 of the respective gripper part 15, 17 are connected to each other by means of several connecting elements 42, here by way of example connecting screws. The tool holder gripping contour 19 and the tool gripping contour 21 are formed on the plate body 39 of the respective gripper part 15, 17. Recesses, here by way of example bores, are provided on the plate body 41 of the respective gripper part 15, 17 for connecting the gripper parts 15, 17 to the actuator 23. Furthermore, the plate bodies 41 of the gripper parts 15, 17 are identically designed and configured. In addition, the gripper parts 15, 17 are essentially mirror-symmetrical to each other.

[0035] What's next in Fig. 1As shown, system 1 also includes a controllable shrinking and measuring station 43. The shrinking and measuring station 43 is also located within the gripping range of the gripper 13 of the robot arm 11. According to Fig. 2 The shrinking and measuring station 43 has a rotary spindle 45 that can be driven by a drive device. The rotary spindle 45 has a holding device 47 ( Fig. 6) for holding a tool holder 5 or a complete tool 3. The holding device 47 is shown here as an example formed by an HSK interface. In addition, the shrink-fit and measuring station 43 also has a measuring device 49, shown here as an example optical device, arranged in the area of ​​the rotary spindle 45 for measuring a complete tool 3 held on the rotary spindle 45. Using the measuring device 49, the length of a complete tool 3 and the diameter of a tool 7 of the complete tool 3 can be determined, for example. During the measurement of a complete tool 3, the rotary spindle 45 can be rotated axially with the complete tool 3 held on it.

[0036] The optical measuring device 49 includes a camera 51 as an image acquisition device for capturing images and / or videos of a complete tool 3 held on the rotary spindle 45. The measuring device 49 is also connected to a screen 53 for displaying the camera images. Furthermore, the measuring device 49 is also connected to a data transmission device (not shown) for wirelessly transmitting the determined dimensions of the complete tool as data to an RFID chip in a tool holder 5.

[0037] As in Fig. 2As further shown, the shrink-fit and measuring station 43 also has a heating device arranged in the area of ​​the rotary spindle 45 for heating the shrink-fit chuck of a tool holder 5 mounted on the rotary spindle 45. The heating device here comprises an annular coil element 55, which includes an induction coil and can be placed on a tool holder 5 for inductively heating a shrink-fit chuck.

[0038] Based on the Figs. 4 to 6 The construction of the rotary spindle 45 will now be explained in more detail. Fig. 6 A complete tool 3 is mounted on the turning spindle 45. The turning spindle 45 has a Fig. 6The figure shows a spindle element 57, indicated by dashed lines, and an adapter element 59 that is detachably attached to the spindle element 57. The adapter element 59 incorporates a holding device 47 for a tool holder 5. The spindle element 57 is axially rotatable in a spindle holder 61 of the shrink-fit and measuring station 43. In an alternative embodiment of the rotary spindle, the holding device 47 could also be provided on the spindle element itself, thus eliminating the need for the adapter element 59.

[0039] As from Fig. 6As further shown, the turning spindle 45 is equipped with an annular cooling element 63, by means of which the turning spindle 45 is air-cooled. In this way, the heat input into the turning spindle 45 is effectively reduced, thereby enabling the measurement of complete tools 3 held on the turning spindle 45 with increased measuring accuracy. If a heated complete tool 3 is held on the turning spindle 45, it is also cooled by means of the cooling element 63.

[0040] The cooling element 63 here surrounds the adapter element 59 of the rotary spindle 45 in an annular manner. Specifically, the cooling element 63 surrounds a holding section 65 of the adapter element 59, which includes the holding device 47, in an annular manner. The annular cooling element 63 rests against the adapter element 59 of the rotary spindle 45 with both its inner circumferential wall 67 and its end wall 69 in a planar contact. In an alternative design of the rotary spindle, the cooling element 63 could also surround the spindle element 57 in an annular manner.

[0041] Furthermore, the cooling element 63 has a sleeve-shaped inner area 71 and several cooling fins 73 projecting outwards from the inner area 71 ( Fig. 5). Each cooling fin 73 has an inner area with a single, straight cooling fin web, which branches outwards into two straight cooling fin webs. Alternatively, cooling fins with a single, continuously curved cooling fin web could also be provided.

[0042] As in Fig. 2 As further shown, the shrink-fit and measuring station 43 also has a cooling device 75 for cooling measured complete tools 3. The cooling device 75 has several cooling pots 77 arranged in series, each of which can cool a complete tool 3. For this purpose, a complete tool 3 can be arranged in an upside-down orientation, i.e., with the clamped tool 7 facing forward, partially inside a cooling pot 77 and connected to a shrink-fit chuck section 79 ( Fig. 6The tool holder 5 is brought into a flat contact with a cooled inner wall 81 of the cooling pot 77. The cooling pots 77 are liquid-cooled. For attaching the cooling pots 77 to the shrink-fit and measuring station 43, each cooling pot 77 has an outwardly projecting annular flange 82 with continuous recesses through which connecting elements, here by way of example connecting screws, are guided. In addition, each cooling pot 77 is open on the underside.

[0043] What's next in Fig. 1As shown, system 1 also includes a controllable balancing station 83, which can be used to check the balance quality of a measured and cooled complete tool 3. Optionally, the balancing station 83 could also be configured to balance a complete tool 3. System 1 also includes a mobile tool cart 85, which can be loaded with tested complete tools 3. Alternatively, system 1 could also have a high-bay warehouse instead of the tool cart 85. The balancing station 83 and the tool cart 85 are also located within the reach of the gripper 13 of the robot arm 11. Furthermore, system 1 includes a control station 87, which controls the robot arm 11, the shrink-fit and measuring station 43, and the balancing station 83, enabling automated operation of system 1.All controllable devices of plant 1 are modularly networked with each other via a central computer of control station 87 for data and / or signal transmission.

[0044] The following section describes an example of automated operation of system 1, or a method for operating system 1: In the initial situation, the tool cart 9 is loaded with tool holders 5 and tools 7. First, the robot arm 11 picks up a tool holder 5 from the tool cart 9. Using a cleaning device, such as a brush, which may be assigned to the tool cart 9, a mounting bore of the picked-up tool holder 5 is then cleaned. Similarly, the interface area of ​​the rotary spindle can also be cleaned at regular intervals using a wiping device, which can be grasped by the robot arm 11, for example. Subsequently, the tool holder 5 is inserted into the HSK interface of the rotary spindle 45 by the robot arm 11. The HSK interface of the rotary spindle 45 is then closed, so that the tool holder 5 is firmly held on the rotary spindle 45.The tool holder 5 is finally identified by an RFID chip attached to the tool holder 5 and the appropriate program for shrinking in a tool 7 is called up.

[0045] The robot arm 11 then picks up a tool 7 from the tool cart 9. The picked-up tool 7 has a readable code, such as a QR code, barcode, or Data Matrix code, which is read by a reading device, for example, attached to the robot arm 11. After identification and verification of the code, the tool holder 5 is heated by the heating device 53, and the tool 5 is inserted into the tool holder 7 by the robot arm 11. Finally, the tool 5 is shrunk into the tool holder 7, and a desired Z-dimension or length dimension of the complete tool 3 is set using the robot arm 11 and the measuring device 49. Alternatively, instead of setting it using the robot arm 11, the Z-dimension of the complete tool 3 could also be set, for example, by means of a stop element attached to the rotary spindle 45 and extendable from the rotary spindle 45.The stop mandrel serves as a stop for a tool 7 inserted into a tool holder 5.

[0046] The complete tool 3 is then removed from the rotary spindle 45 by the robot arm 11 and placed in one of the cooling pots 77 for cooling until it reaches the desired temperature, for example, room temperature. The temperature of the complete tool 3 is measured by a temperature sensor in the respective cooling pot 77. The cooled complete tool 3 is then removed from the cooling pot 77 by the robot arm 11 and placed in the balancing station 83 for balancing quality checks. The spindle of the balancing station 83 can also be cleaned at regular intervals using a wiping device, for example, one that can be grasped by the robot arm 11. After this check, the complete tool 3 is removed from the balancing station 83 by the robot arm 11.Before measuring the cutting edges of the complete tool 3, the cutting edges are cleaned of dust and other contaminants, for example, by immersing the cutting area of ​​the complete tool 3 in a cleaning bath or by dabbing it with an adhesive substance. The complete tool 3 is then inserted into the HSK interface of the rotary spindle 45. The HSK interface of the rotary spindle 45 is then closed, so that the tool holder 5 is firmly attached to the rotary spindle 45. The complete tool 3 is then identified again by the RFID chip attached to the tool holder 5, and the appropriate program for measuring the complete tool 3 is called up. The complete tool 3 is then measured using the measuring device 49. During this process, the complete tool 3 is rotated axially by the rotary spindle 45.After measurement, the complete tool 3 is removed from the rotary spindle 45 by the robot arm 11 and placed on the tool trolley 85. If the balance quality of the complete tool 3 is insufficient, it can be manually balanced by an operator.

[0047] In an alternative operating mode, the system 1 could also be used for shrinking tools 7 out of tool holders 5. Reference symbol list 1 Attachment 41 plate body 3.
