Description

[0001] Tool

[0002] The invention relates to a tool for marking or machining a machining point on a workpiece.

[0003] Conventional marking and, if necessary, machining tools, known as scribing tools, have a stop and a scale where the distance to the machining point is determined in one direction of the stop. A marking gauge is an example of such a tool. However, if several distances need to be determined in different directions, multiple measuring and marking steps, possibly using different tools, are required. This is not only time-consuming but can also exacerbate measurement inaccuracies at each step.

[0004] DE 3247877 C1 relates to a tool for center punching or chiseling square iron, comprising two mutually movable stop jaws, a central section between them carrying the center punch or chisel, and gear and guide elements connecting the stop jaws and the central section. The gear element is designed as a threaded spindle with right- and left-hand threads, which is mounted in the central section and screwed to the two stop jaws. The guide elements are fixedly arranged in one stop jaw, and the other stop jaw and the central section are slidably guided on it. Coordinate-arranged length measuring elements are also provided, the reading and zero marks of which are aligned with the center punch tip and with the stops provided on the stop jaws.

[0005] US Patent 5915806 A discloses a device comprising a detachable, spring-loaded marking device. The detachable marking device can be moved along either side of the horizontal straight edge, which has ruler markings on each edge of the blade segment, to conveniently draw the desired angle. The combination angle gauge has a rotating straight edge that can be turned from the corner joint to angles of 90° and 45° on either side of the horizontal position. Other angles can also be selected and used with this device, which includes an angle measuring device for precise measurement of the blade angle.The straight edge can be rotated and locked in position to set a precise, pre-defined angle, or it can be used to determine the relative angle between two pre-defined points defined by the extensions of the pivoting blade and the head of the carpenter's square. The device also features an integrated retractable measuring tape that can be pulled out from the corner for accurate and efficient measurement of rafters, beams, and similar applications.

[0006] German patent DE 2550358 A1 discloses a center punch device with a housing having a flat contact surface designed to rest against a workpiece. A center punch extending perpendicular to the contact surface is spring-supported within the housing. A threaded rod running parallel to the contact surface is rotatably mounted within the housing. An adjustable first stop, which is slidable along the threaded rod, is connected to this rod. A second adjustable stop or length measuring element is provided, which is adjustable at a right angle to the threaded rod.

[0007] The task is to provide a tool that solves the problems mentioned above.

[0008] The problem is solved by a tool for marking or machining a machining point on a workpiece with the features of claim 1. The tool is provided with a tool body, a tool guide defining a machining point which is coupled to or encompassed by the tool body and which is configured to guide a marking and / or machining means to a predetermined machining point, and with a length measuring device which is at least partially connected to or encompassed by the tool body and which is configured to determine a distance between a machining point and the predetermined reference point, wherein the reference point is spaced away from the tool body in a longitudinal direction.A distance measuring device is at least partially coupled to the tool body and designed to determine a distance between the machining point and a predetermined reference point, wherein the reference point is spaced from the machining point in a transverse direction perpendicular to the longitudinal direction, and wherein the machining point or the reference point is spaced from the tool body in the transverse direction.

[0009] The tool body has a bearing surface and can be placed on a surface of the tool body. In one embodiment, it is movable on the workpiece in at least one direction. It holds or encompasses the other components. The length measuring device is used to determine distances, for example, to an edge of the workpiece as a reference point in the longitudinal direction. The distance measuring device is used to determine distances, for example, to another edge of the workpiece as a reference point in the transverse direction. The distance measuring device is coupled to the tool body in such a way that it is connected to it directly or via other components. The connection can be fixed or movable, so that the distance measuring device or the component coupling it is movable relative to the tool body, for example, displaceable in the longitudinal direction. The tool guide is also coupled to the tool body in this way.Both the length measuring device and the distance measuring device allow the definition of a machining point whose distances to the reference point and datum point lie beyond the tool body. This can be done, for example, using tape measures on the tool body. This also allows machining points to be marked that are located far from the edges of the workpiece, which serve as the reference point and datum point.

[0010] In one embodiment, a slide is provided as a coupling component between the tool body and the distance measuring device. The slide is guided linearly on the tool body, allowing it to move perpendicular to the longitudinal direction.

[0011] In one embodiment, a stop is provided on the tool body so that it abuts in the transverse direction. The stop corresponds to the reference point, as it abuts an edge of the workpiece to which the transverse distance is to be determined. The distance measuring device is advantageously arranged on the slide and / or the tool body, and the distance between the stop as the reference point and the machining point can be determined by means of the distance measuring device.

[0012] The tool with the features of the aforementioned embodiments is provided with a tool body with a stop designed to strike in a transverse direction, a length measuring device that is at least partially connected to or encompassed by the tool body and that is designed to determine a distance to a predetermined reference point, wherein the reference point is spaced from the tool body in a longitudinal direction perpendicular to the transverse direction.Furthermore, the tool is provided with a slide that is linearly guided on the tool body, so that the slide is movable at an angle to the longitudinal direction, in particular in the transverse direction, and with a tool guide defining the machining point, which is arranged on the slide so that it is movable together with the slide, and which is designed to guide a marking and / or machining means to the machining point, and with a distance measuring device that is arranged on the slide and / or the tool body and by means of which a distance between the stop and the machining point can be determined.

[0013] Marking or machining means transferring the machining point, which can be set on the tool, to the workpiece. This machining point, which is set at a predetermined distance from the reference point on the workpiece in the longitudinal direction and from the stop against which one side of the workpiece rests, is transferred to the workpiece by means of the marking and / or machining tool by marking or machining the workpiece at this point. The transfer is carried out using another tool as a marking and / or machining tool, which performs the marking or machining. This additional tool can also be part of the actual tool. Alternatively, it can be a separate tool that is only moved to the machining point for the purpose of marking or machining.The tool is primarily a marking tool, also known as a scribing tool, used to mark a predetermined position on a workpiece as a semi-finished product for a finished product. Alternatively, the workpiece can be machined at this position.

[0014] Possible marking and machining processes that can be performed at the machining point include center punching, pre-drilling, drilling, milling, scribing, or marking. It is conceivable that only one of these marking and machining processes, or several, can be carried out on the tool. The tool guide can be a scribing device, particularly a center punch. Instead of a center punch, a center drilling device or a laser marking device can also serve as the tool guide. Alternatively, the tool guide can be designed as a scribing tool guide or a drill guide, through which a scribing tool or a drill bit is guided to the workpiece at the machining point. Maintenance of a center punch or center drilling device essentially focuses on checking the punch's indentation tip. It should be replaced if worn.It can be removed, replaced, and reattached simply by unscrewing a center punch holder. Since the center punch or centering drill bit is a precision tool module, careful handling is advisable. Apart from that, however, the entire tool is robust, so minor accidents or oversights during operation, provided they do not involve the center punch or centering drill bit, should not have any negative consequences.

[0015] The workpieces for which this tool is intended are typically long and narrow, such as steel beams or wooden girders. However, the workpieces can also be wider and have a larger surface area, such as kitchen worktops, tabletops, or steel plates.

[0016] The distances for setting the machining point are determined by measuring with various measuring devices integrated into the tool. The tool forms a mobile coordinate system where distances from a machining point can be determined both longitudinally (according to an x-axis) and, in particular, transversely (according to a y-axis). This allows the workpiece to be marked at the machining point, which has predetermined distances to the side of the workpiece where the stop rests and to the reference point, which is, for example, an end face of the workpiece. Longitudinal distances are determined using the length measuring device. Transverse distances are determined using the distance measuring device on the slide.The tool guide is positioned at the machining point by a longitudinal movement of the workpiece body and a movement of the slide relative to the tool body, which occurs at an angle to the longitudinal direction, specifically perpendicularly, i.e., in the transverse direction. The stop extends along the underside of the tool body and can be an integral part of the tool body. The stop can be, for example, a fixed stop or a roller stop.

[0017] Length measurement, particularly in the longitudinal direction, can be performed in various ways. For example, a measuring tape, a laser measuring device (such as a laser distance meter), a wheel, a retractable measuring cord, a measuring scale, or a magnetic tape measuring device with a magnetic measuring tape can be used as a length measuring device. Such length measuring devices include at least one extendable component that, when extended, reaches the reference point. To increase the accuracy of the length measurement, the length measuring device includes a stop that can be placed against the reference point. In the case of a measuring tape, this could be, for example, a rectangularly angled end piece. In an alternative approach, the length measuring device includes a first component that is coupled to or encompassed by the tool body, and a separate or separable second component that can be positioned at a distance from the first component and placed at the reference point.Such a two-part approach is used, for example, in laser measurement. The separate component can be a stop that is placed at the end of the workpiece, and up to which the laser measurement is taken with a laser mounted on the tool body. The wheel is an exemplary approach for a length measuring device designed to measure the distance along which the tool body has been moved longitudinally from the reference point. The rolling wheel determines the distance traveled. The length measurement methods described above can be used not only for length measuring devices but also for distance measuring devices.

[0018] A measuring scale on the slide is suitable as a distance measuring device, allowing the distance of the machining point from the stop to be read. Alternatively, an electronic scale can be used as a slide.

[0019] The position of the length measuring device or the distance measuring device on the tool body or the slide can be located away from the machining point and is not predetermined. However, the distance from the machining point is taken into account as a bias during the measurement. It makes no difference whether the measurement is taken to an edge or from an edge of the workpiece to the machining point.

[0020] Advantageously, a longitudinal locking device is provided, which allows the tool body to be fixed to a workpiece resting against the stop, thus preventing movement of the tool body in the longitudinal direction along the workpiece. In this way, the tool body is held in its position. A transverse locking device, designed to prevent movement of the slide perpendicular to the longitudinal direction, particularly in the transverse direction, prevents the displacement of the set machining point relative to the tool body, ensuring that the selected machining process can be carried out safely at the set machining point and that the machining point does not shift.

[0021] In one embodiment, the slide is pivotable, allowing the angle between the slide and the longitudinal direction to be changed. This angle can be varied between 180 and 0 degrees. This allows for greater freedom when setting the machining point. The previously described approaches for length measuring devices are primarily used to measure longer distances where the reference point is spaced away from the tool body. This distance can be several meters. To also be able to measure significantly shorter distances where the reference point is not located beyond the tool body, the length measuring device incorporates additional length measurement means on the tool body itself, provided the reference point lies within the longitudinal extent of the tool body.

[0022] In addition to the first measuring device for long lengths, a second measuring device is also provided on the tool body. The measuring range of the first length measuring device is larger than that of the second. The measuring ranges can overlap. The second measuring range can also be encompassed by the first. Nevertheless, in this case, the second measuring device enables simpler, more convenient, or more accurate measurement.

[0023] In one embodiment, the second measuring device includes a measuring scale on the tool body and / or on the slide to measure distances from the machining point in the longitudinal direction, even if the reference point is located inside the tool body.

[0024] Additionally, a marking device for further markings can be provided on the slide, spaced apart from the tool guide. The marking device has, for example, at least one edge and / or angle for marking lines and / or another measuring scale. In this way, in addition to marking the machining point, lines and / or angles can also be scribed. The tool described above is suitable for DIY enthusiasts and various trades. Metalworkers often drill holes in steel beams, frames, or other metal structures. For example, they need to drill holes for screws or bolts to join components. Carpenters frequently work with long wooden beams and girders. They make markings and drill holes for joints, screws, or nails. For example, they need to drill holes for wooden dowels or screws in load-bearing wooden structures.Carpenters work with long pieces of wood, such as furniture components or stair treads. They must drill precise holes and make markings for joints and fasteners, for example, for assembling stair railings or cabinet panels. Metalworkers work with long metal profiles and pipes. They must drill holes for welds, bolts, or other fasteners. For example, they drill holes in railing posts or metal frames. Electricians sometimes work with long cable trays or conduits. They must drill holes for fasteners or feedthroughs. For example, they drill holes in cable trays for mounting to walls or ceilings. In shipyards, shipbuilders must drill holes and make markings on long steel plates and beams. These are needed to assemble the ship's structure, such as when building hulls or decks.Engineering companies that construct bridges need to drill holes in long steel or concrete components, for example, for bolt holes in bridge girders or connection points. Companies specializing in facade construction often need to drill holes in long facade profiles or beams to attach them to the building envelope. In the industrial manufacturing of furniture, long wooden parts are frequently processed. Drilling and marking are necessary here to assemble parts such as tabletops, cabinet panels, or shelves. In the automotive and commercial vehicle industries, holes must be drilled in long metal or plastic parts, such as chassis or body panels, to connect or assemble components. Companies that manufacture wind turbines need to drill holes in long parts such as tower segments or rotor blades to securely connect them.Companies specializing in the construction of large steel structures, such as skyscrapers or industrial plants, must precisely drill holes and make markings on long steel beams and profiles. Railway construction companies must drill holes in long rails to prepare them for assembly or fastening.

[0040] In the figures, identical or functionally equivalent components are provided with the same reference symbols.

[0041] Fig. 1 shows in a three-dimensional view an embodiment of a tool 1 for marking, in particular for scribing a machining point on a workpiece 3.

[0042] In an exemplary coordinate system, the x-axis runs longitudinally, the y-axis transversely, and the z-axis perpendicular to these directions. The tool 1 comprises a tool body 5 with a lower support surface and a stop 7. The tool body 5 can be positioned against a workpiece 3 such that the stop 7 abuts a side surface 31 of the workpiece 3 in the transverse direction, and the tool body 5 rests with its support surface on the top surface 34 of the workpiece 3. Both the side surface 31 and the top surface 34 of the workpiece 3 are preferably flat. The abutting tool 1 is displaceable longitudinally along the side surface 31 with the stop 7. A longitudinal locking device (not shown in Fig. 1) can be provided that blocks the longitudinal movement in order to lock the tool body 5 at a predetermined position on the side surface 31.

[0043] The tool body 5 has a trapezoidal base shape. Near its longer base side, the stop 7 extends along its underside. The tool body 5 is made of metal, is a single piece, and is formed with the stop 7 such that the bearing surface of the tool body 5, which points in the z-direction and rests on the top surface 34 of the workpiece 3, and a stop surface, which abuts the side surface 31, are perpendicular to each other, with the stop surface pointing in the transverse direction so that the stop 7 abuts in the transverse direction. An alternative embodiment of the tool body 5 may comprise a different material, for example plastic, and / or be multi-part.

[0044] The tool 1 comprises a length measuring device 13, which includes a tape measure 15 with an extendable measuring band 17 as the first measuring device 21. The measuring band 17 has a stop 55 that can be placed against an edge. The tape measure 15 is arranged and attached to the tool body 5 so that its measuring band 17 can be extended longitudinally. Measuring scales are provided as the second measuring device 23 of the length measuring device 13; these are explained in more detail in connection with the following figures. Using the length measuring devices 13, a distance in the longitudinal direction to a reference point, for example, the end face 33 of the workpiece 3, can be determined.

[0045] A laterally movable slide 19 is arranged in a linear guide 25 on the tool body 5. The linear guide 25 runs parallel to the trapezoidal height of the trapezoidal tool body 5. A recess 39 corresponding to the width of the slide head is located in the tool body 5, into which the head can be lowered when the slide 19 is retracted. The slide 19 is movable in the transverse direction relative to the stop 7 and the tool body 5 on the upper surface 34 of the workpiece 3. A locking screw 81, acting as a transverse locking device 11, can fix the position of the slide 19 relative to the tool body 5. Measuring scales are provided on the slide 19 as a distance measuring device 27. The distance measuring device 27, with its measuring scales, is coupled to the tool body 5 by the slide 19 in such a way that it is movable relative to the tool body 5. The slider 19 and the measuring scales are described in more detail in connection with the following figures.The distance measuring device 27 determines the distance to a predetermined reference point 32.

[0046] A center punch device 29 for marking a machining point on the workpiece 3 is arranged on the slide 19. The center punch device 29 is coupled to the tool body 5 by the slide 19 in such a way that it is movable relative to the tool body 5. The center punch device 29 can be moved to a predetermined machining point on the tool 3 by a longitudinal movement of the tool body 5 and a transverse movement of the slide 19, such that the machining point has predetermined distances to the side surface 31, against which the tool 1 abuts, and to a reference point, which is, for example, an end face 33 of the workpiece 3. A distance between the stop 7 as reference point 32 and the machining point can be read on a first measuring scale 41, which serves as a distance measuring device 27 on the slide 19. The distance to the end face 33 can be adjusted using the length measuring device 13.The center punch device 29 comprises a tool guide in which a spring-loaded indenter is mounted so that it is spaced apart from the top surface 34 of the workpiece. By overcoming the spring force, the indenter is pressed against the top surface 34, thus creating a point-shaped mark at the machining point.

[0047] Fig. 2 shows a top view of the tool 1, which is positioned on a workpiece 3 in a first position where the machining point 20 is near the end face 33 of the workpiece 3. The machining point 20 is marked by a cross.

[0048] The slide 19 has an L-shaped base with a long, transverse leg 51, which is guided longitudinally, and a short leg 53, which runs perpendicular to it and forms the slide head. The long and short legs 51, 53 form a right angle and edges 35 on which the vertex 37 of the angle, a right angle, or a transverse or longitudinal line can be marked on the workpiece 3 using a pin, scriber, or center punch. When the slide 19 is retracted, its head is recessed in the recess 39 of the tool body 5.

[0049] The tool guide of the center punch device 29 is offset transversely to the apex 37. In an alternative embodiment, a longitudinal offset is also possible. On the long leg 51 of the slide 19, there is a first scale 41, which indicates the distance of the tool guide, and the machining point 20 that can be marked with it, in the transverse direction. On the short leg 53, there is a second scale 42, which indicates the distance of the tool guide, and the machining point 20 that can be marked with it, from a reference point 30 in the longitudinal direction. The zero point of the scales 41, 42, 44 is the machining point 20, defined by the tool guide in the center punch device 29. On the side of the long leg 51 opposite the first scale 41, there is a third scale 43, which indicates the distance from the apex 37 in the transverse direction. On the side of the short leg 53 opposite the second scale 42 is a fourth scale 44, which indicates the distance from the vertex 37 in the longitudinal direction.In this embodiment, it corresponds to the second scale 42.

[0050] A marking 45 on the tool body 5, corresponding to the stop surface 7, allows the distance between the machining point 20 and the side surface 31 of the workpiece 3 to be read as reference point 32. A distance from the end face 33 as reference point 30, which is less than the length of the second scale 42, as shown in Fig. 2, can be read on the second scale 42 or the fourth scale 44.

[0051] To set an exemplary machining point with a distance of 190mm to the side surface 31 and 10mm to the end surface 33, the tool body 5 is in the stop and the slide 19 is positioned such that these values ​​can be read on the first scale 41 at the mark 47 or on the second or fourth scale 42, 44 at the end surface 33 as reference point 30.

[0052] Fig. 3 shows a top view of the tool 1, which is positioned against the workpiece 3 in a second position. The end face 33 is spaced away from the slide head, but extends below the tool body 5.

[0053] On the tool body 5 is a fifth scale 45, which extends longitudinally beyond the recess 39 for the slide head. It is a continuation of the second and fourth scales 42, 44, and its zero point corresponds to the machining point 20. Above and below the fifth scale 45 are longitudinal viewing slots 49 extending through the tool body 5. Through the viewing slots 49, the end face 33 of the workpiece 3 is visible as a reference point 30, so that its distance from the tool guide and thus from the machining point 20 can be read on the fifth scale 45.

[0054] To set an exemplary machining point with a distance of 190mm to the side surface 31 and 30mm to the end surface 33 as reference point 30, the tool body 5 is in the stop and the slide 19 is positioned such that 190mm can be read on the first scale 41 at the mark 47 and 30mm on the fifth scale 45 at reference point 30.

[0055] The second and fifth scales 42, 45 form the second measuring device 23 of the length measuring device 13, with which distances to a reference point 30 within the longitudinal extent of the tool body 5 can be measured.

[0056] Fig. 4 shows a top view of the tool 1, which is positioned on the workpiece 3 in a third position. The end face 33 of the workpiece 3 is spaced longitudinally away from the tool body 5.

[0057] In this position, the distance to the tool guide of the center punch device 29, and thus to the machining point 20, is determined by the longitudinally extended measuring tape 17 of the tape measure 15. The measuring tape 17 has an end stop 55, which allows it to be positioned against the end face 33 as a reference point 30. The tape measure 15 makes it possible to measure the distance to a reference point 30, even if this is beyond the tool body 5. In one embodiment, the scale of the measuring tape 17 is such that the distance between the machining point 20 and the tape measure 15 is already taken into account as a bias, so that the extended measuring tape 17 at the housing outlet of the tape measure 15 indicates the distance of the reference point 30 to the machining point 20.To set an exemplary machining point with a distance of 190mm to the side surface 31 and 3000mm to the end surface 33, the tool body 5 is in the stop and the slide 19 is positioned such that 190mm is read on the first scale 41 and 3000mm on the measuring tape 17.

[0058] The described tool 1 allows a machining point 20 to be marked, the distance of which in the transverse direction from a side abutting the stop 7 and a reference point 30 in the longitudinal direction, for example an end face 33, is determined in the same operation by the same tool 1. The reference point 30 can be located beyond the tool body 5, so that a machining point 20 can also be marked at a large distance from a selected reference point 30. This is useful, for example, for long workpieces such as beams or boards.

[0059] Fig. 5 shows another embodiment of a tool 1, which includes a wheel 57 with a digital display 59 as a first measuring device 21, serving as a length measuring device 13. The length measurement is performed by detecting the rotation of the wheel 57 when the tool 1 is moved longitudinally. The wheel 57 is positioned at the reference point 30, and then the tool 1 is moved longitudinally within its stop until the desired distance from the reference point 30, to which the distance is to be determined, is reached. The distance traveled is displayed on the digital display 59. Advantageously, the distance between the wheel 57 and the machining point 20 is already taken into account as a bias in the display. The other features and the remaining adjustment procedure for the machining point 20 are the same as in the previous embodiment.

[0060] Fig. 6 shows another embodiment of the tool 1, which comprises a magnetic tape measuring device 61 with a digital display 59 as a length measuring device 13. A magnetic tape sensor is provided in the magnetic tape measuring device 61 as a read head. A magnetic tape 63 is attached to the top of the workpiece 3. The magnetic tape 63 has magnetic fields that are detected by the read head. The movement of the read head along the magnetic tape 63 is converted into signals that are displayed as a distance in the digital display 59. The magnetic tape sensor can be absolute or incremental.

[0061] The magnetic tape 63, for example, includes longitudinal sections with a measuring tape for visual length determination, adhesive tape for fastening, and the magnetic metal tape or magnetic rubber tape made of a rubber-like, flexible plastic. The latter has particularly good adhesion, for example, to workpieces made of aluminum or wood.

[0062] In this embodiment, the movable slide 19 is also designed to pivot about a joint 65, so that it can be moved not only perpendicular to the longitudinal direction but also at an adjustable angle to it. When the slide 19 is at a right angle, the distance measuring device 27 with the first scale 41 does not measure the distance perpendicular to the stop 7, but rather along the side of the slide 19 that forms the angle. The center punch device 29 is coupled to the tool body 5 by the slide 19 in such a way that it is movable relative to the tool body 5.

[0063] Fig. 7 shows an embodiment of a first measuring device 21 of a length measuring device 13 with separate components, of which only one component is mounted on the tool body (not shown in Fig. 7). The laser length measuring device 67 has a laser with a digital display 59 on the tool body 5 and, as a separate component, a stop plate 56 serving as a stop, which can be attached to the workpiece 3 by means of a screw clamp 69 or a magnet 71, so that it is flush with the end face 33 and projects beyond the top surface 34. The distance to the stop plate 56, and thus to the end face 33, is displayed in the digital display 59. Advantageously, the additional distance to the tool guide, which defines the machining point 20, is already taken into account as a bias in the display.

[0064] In an alternative embodiment, the laser can be part of a separate component, wherein the laser determines the distance to an area of ​​the tool body 5 designed as a reflective surface.

[0065] Fig. 8 shows a section through an embodiment of a center punch device 29 on the slide 19. It comprises a housing 73 and a marking point 75, the end of which protrudes from the top of the housing 73. A spring 77 tensions the marking point 75 against the housing lid such that the point is spaced away from the workpiece 3. The spring 77 and the housing 73 form the tool guide 87 for the marking point 75. If the end of the marking point 75 is moved downwards against the spring force, for example by a hammer blow, the marking point 75 is pressed onto the workpiece 3 and makes a point-shaped indentation as a mark at the machining point 20. When the pressure is released, the spring force causes the marking point 75 to move away from the workpiece 3 again.Although the center punch device 29 is designed for point-shaped markings, it can also be used to scribe lines in the longitudinal and transverse directions if the tool body 5 or the slide 19 is moved while the tip is pressed down.

[0066] Figures 9 and 10 illustrate two embodiments of clamping devices as longitudinal locking devices 9 to prevent longitudinal movement of the tool 1. Such clamping devices are provided on the tool body 5. The other components of the tool are not shown for clarity. Figure 9 shows a clamping device as a longitudinal locking device 9 with two opposing jaws 79, one of which is fixed and the other movable in the transverse direction and lockable by means of a clamping screw 81. The workpiece 3 is clamped between the jaws 79. Such a clamping device is suitable, for example, for boards.

[0067] Fig. 10 shows a clamping device as longitudinal locking devices 9 with a fixed and a movable, lockable jaw 79, between which the workpiece can be clamped perpendicular to the longitudinal and transverse directions. The clamping, similar to that of a screw clamp, is effected by moving a lever 83 downwards, which presses the movable jaw 79 against the workpiece 3 and locks it in place.

[0068] Fig. 11 shows a three-dimensional view of another embodiment of a tool 1 for marking and guiding a drill.

[0069] The tool comprises a tool body 5 with a rectangular base and a stop 7 on its underside. It can be positioned against a workpiece 3 such that the stop 7 abuts a side surface 31 of the workpiece 3 in a transverse direction, and the tool body 5 rests on a top surface 34 of the workpiece 3. The workpiece 3 can be, for example, a wooden board, a steel plate, or an aluminum plate. A long part, such as a profile, is also a possible workpiece 3.

[0070] The tool body 5 has a T-shaped cross-section due to the stop 5. The tool body 5 has a handle 85 on its upper surface to facilitate longitudinal movement of the tool body 5 when it is pushed along the side surface 31 of the workpiece 3 against the stop. A longitudinal locking device 9 with a reversible lever 83 blocks the longitudinal movement and fixes the tool body 5 to the workpiece 3. The longitudinal locking device 9 can be designed as a clamping device or a suction device with a suction cup that can be activated by the lever 83. Alternatively or additionally, it may have a magnet.

[0071] A slide 19 is movable in a linear guide 25 on the tool body 5 in the transverse direction. A sleeve-shaped tool guide 87 is located on the upper side of the slide 19 and surrounds a hole in the slide 19. The tool guide 87 is coupled to the tool body 5 by the slide 19 in such a way that it is movable relative to the tool body 5. The hole in the tool guide defines the machining point 20. The slide 19 is elongated and rectangular with a scale 41. The zero point corresponds to the machining point 20, so that its distance from the stop 7 can be read at a mark 47 on the linear guide 25, which corresponds to the stop 7.

[0072] The sleeve-shaped tool guide 87 serves as a center punch or centering device. Both a center punch and a drill bit 88 can be inserted into the tool guide 87 to mark the desired machining point 20 or, centered by the sleeve-shaped tool guide 87, to drill a hole. In one embodiment, a cordless screwdriver 90 is fixedly connected to the tool guide 87 with a drill bit 88 or with a centering drill bit. Alternatively, there is no fixed connection between such a cordless screwdriver 90 and the tool guide 87. A center punch can also be fixedly connected to the tool guide 87 or guided loosely within it. A spring mechanism may be provided.

[0073] The tool 1 comprises a length measuring device 13, which includes a retractable measuring tape 15 with an extendable measuring band 17. The housing of the length measuring device is arranged laterally to the side of the tool body 5 and extends longitudinally. The length measuring device 13 has a digital display 59. At the end of the measuring band 17 is a spacer 89, which can be fixedly or detachably connected to the measuring band 17. The spacer 89 can be placed against the end face 33 below the housing as a reference point 30 and makes it possible to measure distances below the housing as well, since it forms an offset opposite to the extension direction of the measuring band 17. The digital display 59 is designed to take into account the additional distance to the tool guide 87, which defines the machining point 20, as a bias. The length of the spacer 89 can also be taken into account.

[0074] Fig. 12 shows another embodiment of a tool 1. It has a flat tool body 5 that rests on the top surface 34 of a workpiece 3. A stop 7 extends vertically downwards along the tool body 5. On the top surface of the tool body 5 is a handle 85 for moving the tool body 5, which abuts the workpiece 3, in a longitudinal direction. A slide 19 runs transversely to the longitudinal direction in a linear guide 25, which is formed as a groove in the tool body 5. The width of the groove and the width of the slide 19, which has an elongated, rectangular base, correspond. The slide 19 has a transverse slot into which a locking screw 81 engages, holding the slide 19 in the groove and allowing it to be locked. A center punch device 29, as already described in connection with Fig. 8, is located at the head of the slide 19.The center punch device 29 is coupled to the tool body 5 by the slide 19 in such a way that it is movable relative to the tool body 5.

[0075] A length measuring device 13, consisting of a tape measure 15 with an extendable measuring band 17, is provided on the tool body 5. The tool body 5 is shaped such that a section 6 of the tool body 5 extends longitudinally beyond the tape measure 15 in its rest position, i.e., with the measuring band 17 retracted. A scale 45 is arranged along a longitudinal slot 93 in this section 6. A movable longitudinal stop 91 can be inserted into the longitudinal slot 93 from a rest position, as shown in Fig. 12, through transverse slots 94 that open into the longitudinal slot 93. The stop can be moved within the slot and fixed by means of locking screws 81. A vernier scale is located on the upper side of the longitudinal stop 91.

[0076] Because of the area 6 of the tool body 5 extending beyond the tape measure 15, a distance within this area can be determined both with the longitudinal stop 91 and with the tape measure 15.

[0077] Fig. 13 shows a bottom view of the tool 1 with the longitudinal stop 91 in its rest position. For clarity, the transverse stop 7 will be referred to as the transverse stop 7 in the following. In its rest position, the longitudinal stop 91 is positioned facing away from the striking side of the transverse stop 7. It is not engaged in the longitudinal slot 93. The transverse stop 7 has a recess 95 through which the longitudinal stop 91 can move along the transverse slots 94 when it is inserted into the longitudinal slot 93. Within the longitudinal slot 93, it is moved longitudinally and locked in place.

[0078] Fig. 14 shows a bottom view of the tool 1 with the longitudinal stop 91, which has been positioned in the longitudinal slot 93. The workpiece 3 then abuts both the transverse stop 7 and the longitudinal stop 91.

[0079] Marking comprises several steps: longitudinal positioning, transverse positioning, and center punching. For longitudinal positioning, the tape measure 15 or the scale 45 can be used as the first and second measuring devices 21 and 23, respectively. For large distances (e.g.,

[0080] For distances of 70-15000 mm, the tape measure 15 is used as the first measuring device 21, and for small distances (e.g., 0-70 mm), the scale 45 in combination with the longitudinal stop 91 is used as the second measuring device 23. Due to structural limitations, the first measuring device cannot be used to start measurements from a distance of 0 mm, as the machining point could intersect the measuring device and obstruct the measurement. The measured value is determined by simply hooking the stop 55 of the tape measure 17 onto the end face of the workpiece 3. By subsequently moving the tool 1, the tape measure 17 unwinds, allowing the changing distance to be continuously read.

[0081] In contrast, the scale 45 is used to determine distances within a smaller range. Adjustment is achieved by inserting the longitudinal stop 91 transversely into the longitudinal slot 93. In doing so, the longitudinal stop 91 passes through the transverse stop 7. The desired distance can then be set longitudinally by moving the longitudinal stop 91. The longitudinal stop 91 can be fitted with a locking pin, thus eliminating the need for the described insertion. At the same time, the tape measure 15 is in its rest position: the measuring tape 17 is retracted, and the stop 55 of the measuring tape 15 is not engaged.

[0082] Positioning in the transverse direction is similar to using a marking gauge. For this, the locking screw 81 for the slider 19 must be loosened, the desired distance set by moving the slider 19, and the locking screw 81 tightened again.

[0083] The desired machining point 20 is marked using a spring-loaded center punch 29. After approaching the machining point 20, the center punch 29 is struck with a hammer. This compresses the integrated spring, causing the indentation tip to penetrate the workpiece surface and create a permanent deformation, thus marking the point. After actuation, the spring force returns the center punch 29 to its rest position.

[0084] Fig. 15 shows another embodiment of a tool 1 for marking or machining a machining point 20. The tool 1 is particularly suitable for workpieces 3 with a large top surface 34. In Fig. 15, a large plate is shown as an example of a workpiece 3. In accordance with the previously used designations, the mutually perpendicular edges are referred to as the end face 33 and the side surface 31.

[0085] The tool body 5 is plate-shaped, in this case with a rectangular contour, so that it can be placed on the top surface 34 of the workpiece 3 and slid on it. In contrast to the previous embodiments, the tool body 5 has no stop. A center punch device 29 with a tool guide 87 defining the machining point 20 is arranged on the tool body 5.

[0086] A length measuring device 13 is arranged laterally to the tool body 5 and is rigidly connected to the tool body 5. It is designed to determine the distance between the machining point 20 and a predetermined reference point 30, the reference point 30 being longitudinally spaced from the tool body 5. The reference point 30 is the end face 33 of the workpiece 3. The length measuring device 13 is designed as a tape measure 15, which is oriented such that its measuring tape 17 is extendable in the longitudinal direction, which is marked x.

[0087] A distance measuring device 27 is also attached to the side of the tool body 5 and is connected to the tool body 5. It is designed to determine the distance between the machining point 20 and a predetermined reference point 32, the reference point 32 being spaced from the machining point 20 in the transverse direction, perpendicular to the longitudinal direction. The reference point 32 is the side surface 31 of the workpiece 3, which runs perpendicular to the aforementioned end face 33. The distance measuring device 32 is designed as a further tape measure 15, which is oriented such that its measuring band 17 can be extended in the transverse direction, which is denoted by y. The two tape measures 15 of the length measuring device 13 and the distance measuring device 27 are arranged such that their measuring bands 15 can be extended at right angles to each other.

[0088] This tool 1 is suitable for large-area plates where the machining point 20 needs to be marked at a large distance from two mutually perpendicular edges. For example, the workpiece 3 is a square plate with an edge length of 3000 mm. The stops 55 of the measuring bands 17 are attached to the mutually perpendicular edges so that the distances to the machining point 20 on the tool body 5 can be read from the extended measuring bands 17.

[0089] If the tape measures 15 are designed and aligned such that the measuring tapes 17 can each display a range of values ​​from zero, corresponding to the machining point 20, up to their maximum extension length, scales on the tool body 5 are not required. Nevertheless, in an alternative embodiment, scales extending in the longitudinal and transverse directions can be provided on the tool body 5 to easily determine the distance to reference points 30 and reference points 32 located within the tool body contour.

[0090] Instead of the tape measures 15, other measuring devices can also be used as length measuring device 13 and distance measuring device 27, as already mentioned in the previous embodiments, particularly in connection with the length measuring device 13: for example, laser measuring devices 67 and magnetic tape measuring devices 61. Various measuring devices can be used as length measuring device 13 and distance measuring device 27.

[0091] This tool 1 is designed for reference points 30 and reference points 32, which are widely spaced from the tool body 5. This allows large plates to be center-punched and then precisely fitting holes to be drilled using a drill press, ensuring that the holes are identical on every plate.

[0092] Because the machining point 20 is on the tool body 5, instead of on a slide 19 as in the previous embodiments, the device is particularly suitable for marking machining points that are far away from the reference point 32 in the transverse direction. With a slide 19 extended very far, for example 2000 mm, and a stop surface that is only, for example, 200 mm long, the tool guide 87 or the center punch device 29 on the slide 19 can become less stable and less accurate due to play in the slide guide, and the extended slide 19 may even bend.

[0093] The features specified above and in the claims, as well as those discernible from the illustrations, can be advantageously implemented both individually and in various combinations.
