Description

Technical Field

[0001] This invention relates to a system for positioning / orienting a workpiece relative to machine tool components. Background Technology

[0002] As is well known, when clamping a workpiece in machining machinery, the workpiece must be oriented into a specified position. Therefore, the workpiece can be oriented relative to the axis of rotation, and the workpiece can be arranged to rotate around this axis of rotation. Summary of the Invention

[0003] Therefore, the object of the present invention is to improve a system of machine tool components including a workpiece and a machine tool, wherein orientation can be easily implemented.

[0004] According to the invention, this objective is achieved by a system based on the features described in claim 1.

[0005] An important feature of the present invention in a system for positioning a workpiece relative to a machine tool component, particularly relative to machining machinery, is that the system comprises a workpiece, a machine tool component, a clamping component, and an adapter component, wherein the adapter component has a bolt-shaped region that is at least partially inserted into a hole in the workpiece, particularly into a hole centrally located in the workpiece, wherein the adapter component is held, particularly and / or centeredly held, relative to the clamping component by means of a threaded pin screwed into a radially oriented threaded hole in the clamping component, wherein the spindle region of the machine tool component, particularly the machine tool component, is at least partially inserted into a recess in the clamping component.

[0006] Advantageously, the adapter can be screwed into the workpiece, thus allowing for precise orientation relative to the workpiece. The adapter can be oriented and centered relative to the clamping component by means of a threaded pin. A notch is constructed on the clamping component, in which the spindle area of ​​the machine tool component can be clamped.

[0007] The two-piece implementation allows for the use of different adapter components, which differ in their implementation in the bolt-shaped area, thus enabling connection to different workpieces. Facing the clamping component, these adapter components are always implemented in the same form, ensuring that all adapter components can connect to the clamping component. Furthermore, the workpiece only needs to have a centrally located hole, particularly a threaded hole, to mate with the adapter component. The clamping component has a recess designed to match the machine tool component to be clamped in the machining process. Therefore, the recess can fit the machine tool component.

[0008] In an advantageous embodiment, the hole in the workpiece is configured as a threaded hole, and the plug-like region is configured as a threaded region, wherein the mating component is screwed into the threaded hole with its plug-like region. Advantageously, this enables a stable and precisely oriented connection.

[0009] In an advantageous embodiment, the threaded pins screwed into the radially oriented threaded holes of the clamping component are spaced apart from each other, particularly uniformly, in the circumferential direction. Advantageously, orientation and centering can be easily achieved here.

[0010] In an advantageous embodiment, radially oriented threaded holes of the clamping component are arranged in an annular region of the clamping component, which abuts a disc-shaped region of the clamping component on its workpiece-facing side. The disc-shaped region includes a radial distance / radial interval region covered by the annular region. In particular, the disc-shaped region and the annular region are integrally formed, especially as a single piece. The advantage here is that the orientation of the adapter component and thus the orientation of the workpiece can be achieved in a simple manner.

[0011] In an advantageous embodiment, the adapter is arranged, in particular, clamped in a recess of a clamping member, wherein the adapter is spaced apart from the clamping member by means of a threaded pin. Advantageously, the adapter is arranged in a form-locking manner.

[0012] In an advantageous embodiment, the adapter component is integrally formed, particularly as a single piece, of a bolt-shaped region of the adapter component and a disc-shaped region adjacent to the bolt-shaped region. Advantageously, this allows for a stable structure and thus permits high loads.

[0013] In an advantageous design, the outer periphery of the adapter component, particularly in the disc-shaped area of ​​the adapter component, has a cylindrical surface on which a threaded pin is supported. Advantageously, this allows for precise workpiece orientation during fine and accurate machining of the surface.

[0014] In an advantageous embodiment, a threaded hole is arranged in the adapter component, axially penetrating the adapter component, particularly through a disc-shaped region of the adapter component. A threaded pin is screwed into the threaded hole, and the threaded pin is supported on the workpiece, particularly on the flat end face of the workpiece facing the adapter component. Advantageously, the threaded hole can be arranged in a stable region.

[0015] In an advantageous embodiment, particularly at the same radial distance as the threaded hole axially passing through the adapter, two circumferentially spaced holes, especially the farthest from each other, are arranged on the adapter. A pin fixed or formed on the rod can be inserted into these holes, thereby enabling the adapter, particularly with high torque, to be screwed into the workpiece. Advantageously, simple operation is also possible after installation.

[0016] In an advantageous design, the rod has a rough and / or grooved area that is spaced apart from the pin of the rod. Advantageously, this results in the reliable application of high torque through improved gripping properties.

[0017] In an advantageous design, the clamping component has axially through holes, through which a threaded pin, screwed into an axially oriented threaded hole in the adapter component, can be manipulated, particularly screwed, using a tool. Specifically, the clamping component has axially through holes arranged at the same radial distance as the threaded pin screwed into the axially oriented threaded hole in the adapter component. Advantageously, calibration or recalibration can be performed even after the adapter component has been clamped in the clamping component, and simple operability is achieved.

[0018] In an advantageous embodiment, the rod has two pins on its side facing the adapter, spaced apart from each other by a first distance, protruding toward the adapter. These pins extend into corresponding axially oriented holes, particularly through holes penetrating the adapter. Advantageously, this allows for the application of high torque.

[0019] In an advantageous embodiment, the rod has two additional, axially projecting pins on its side opposite to the adapter, spaced apart by a second distance, wherein the first distance is greater than the second distance. Advantageously, this allows for the manipulation of adapters of different sizes. Therefore, the rod can be used for different structural dimensions.

[0020] In an advantageous embodiment, the axial direction coincides with the axis of symmetry of the clamping component and / or the axis of symmetry of the adapter component, particularly wherein the radial and circumferential directions are based on this axis of symmetry. Advantageously, the workpiece can rotate about the axis of rotation and can be clamped on the mandrel region of the machine tool component, wherein the axis of rotation passes through the tip of the mandrel region.

[0021] In an advantageous embodiment, the clamping and / or adapting components have at least discrete rotational symmetry, particularly continuous rotational symmetry during their manufacture prior to the formation of the hole. Advantageously, the forces are distributed as uniformly as possible around the periphery.

[0022] Other advantages arise from the dependent claims. The invention is not limited to the combination of features described in the claims. For those skilled in the art, particularly from the purposes presented and / or by comparison with the prior art, other meaningful combinations of claims and / or individual claim features and / or specification features and / or drawing features are apparent.

[0029] exist Figure 6 Another corresponding cross-sectional view is shown in [the diagram]. Figure 3 Implemented in the corresponding section BB marked in the map.

[0030] exist Figure 7 The image shows a perspective view of the clamping component 9.

[0031] exist Figure 8 The image shows a perspective view of adapter component 4. Detailed Implementation

[0032] As shown in the accompanying drawings, the system according to the invention enables the workpiece 1, particularly a shaft, such as the output shaft of an industrial transmission device, to be clamped on the spindle region 12 of the machine tool component 13 in machining machinery, especially in machine tools.

[0033] Here, the relative centering of workpiece 1 with respect to machine tool component 13 can be performed with high precision.

[0034] Importantly, the workpiece 1 has a centrally located and / or centrally formed hole into which the plug-shaped region 3 of the adapter 4 can be inserted. Preferably, the hole in the workpiece 1 is configured as a threaded hole and the plug-shaped region 3 is configured as a threaded region, thereby enabling the adapter 4 to be screwed into the hole in the workpiece 1.

[0035] In order to use the tool for manipulation, that is, to screw in the adapter 4, the tool has a rod 8 with two spaced-apart pins 7 on its side facing the adapter 4 that protrude toward the adapter 4. These pins extend into corresponding axially oriented holes 6, specifically through the holes 6 that pass through the adapter 4.

[0036] The axial direction is parallel to the workpiece 1, especially the axis of rotation of the shaft.

[0037] The adapter 4 has other through holes designed as threaded holes. Axially oriented threaded pins 5 are screwed into these threaded holes, thereby fixing the axial distance between the adapter 4 and the workpiece 1 in the axial direction by means of the screwing depth and the corresponding extension of the threaded pins 5. Because multiple, particularly four, spaced apart from each other are arranged circumferentially on the adapter 4, not only is the axial distance between the adapter 4 and the workpiece 1 achieved, but also the orientation of the adapter 4 relative to the workpiece 1 is achieved, thus providing a clearance for the threaded connection between the adapter 4 and the workpiece 1. However, elastic deformability also exists, particularly in the micrometer range, and despite this, a small degree of freedom is achieved.

[0038] The lever 8 has a grooved and / or roughened gripping area 14, which is spaced apart from the pin 7, particularly in the radial direction, i.e., along the longest extension of the lever 8. This improves grip when operating the lever portion 8 and / or prevents the operator's hand from slipping.

[0039] The adapter 4 has a cylindrical surface on its outer periphery, wherein the cylindrical axis belonging to the cylindrical surface is the same as the rotation axis of the workpiece 1.

[0040] Clamping component 9 is aligned with the cylindrical surface.

[0041] The clamping member 9 has a recessed portion in which the adapter member 4 is clamped, wherein radially oriented threaded pins 10, spaced apart from each other in the circumferential direction, and particularly evenly spaced apart from each other in the circumferential direction, are screwed into the threaded holes of the clamping member 9 that radially penetrate the clamping member 9. Here, these threaded pins 10 not only extend radially inward relative to the adapter member 4, but also extend radially outward from the clamping member 9. Therefore, simple operation of the threaded pins 10 can be achieved because the threaded holes of the clamping member 9 for these threaded pins 10 are formed through the annular region of the clamping member 9.

[0042] Ignoring the hole, the clamping member 9 has continuous rotational symmetry, wherein the axis of rotational symmetry is the same as the axis of the annular region. The threaded pin 10 is arranged in the clamping member 9 such that the threaded pin 10, together with the clamping member 9, has eightfold... Rotational symmetry.

[0043] However, the radial distance region covered by the annular region is smaller than the radial distance region covered by the threaded pin 10. This results in the protrusion of both radial sides of the threaded pin 10. Therefore, the manipulation of the threaded pin 10 can be easily performed starting from the radial outside, and the threaded pin 10, extending radially inward from the clamping member 9, achieves the spacing between the clamping member 9 and the adapter member 4.

[0044] In this way, the adapter 4 can be oriented toward the clamping member 9, so that the rotation axis of the workpiece 1 is oriented coaxially, that is, in particular, coincides with the rotational symmetry axis of the clamping member 9.

[0045] The clamping component 9 has axially through holes 11 through which axially oriented threaded pins 5, which are screwed into the adapter component 4, can be manipulated. In this way, the distance between the workpiece 1 and the adapter component 4 can be adjusted.

[0046] Additional axially penetrating holes are formed in the clamping member 9 at the same radial spacing. Through these holes, the distance between the adapter 4 and the clamping member 9 can be adjusted by means of additional axially oriented threaded pins screwed into the threaded holes of the adapter 4. Here, these additional threaded pins press their axial end faces against a preferably flat surface formed on the clamping member 9, which is radially surrounded by an annular region.

[0047] Conversely, the threaded pin 5 presses its end face facing the workpiece 1 against a preferably equally flat surface constructed on the workpiece 1.

[0048] During manufacturing, the adapter 4 is screwed into the center hole 2 of the workpiece by means of a tool in the first method step.

[0049] For this purpose, a rod 8 is used, on the side of the rod facing the adapter 4, with at least two pins 7 that can be inserted into holes 6 in the adapter 4. In particular, two holes 6 are arranged diametrically opposite each other on the adapter 4, and specifically, they have an included angle of 180° with each other in the circumferential direction. In this way, the maximum possible torque is achieved for screwing the adapter 4 into the threaded hole of the workpiece 1.

[0050] The gripping area 14, separated from the pin 7, is rough or grooved on the rod 8 to prevent the operator's hand from slipping.

[0051] The farther the gripping area 14 is from the pin, the higher the torque that the operator of the lever 8 can input.

[0052] On the side away from workpiece 1, rod 8 also has two pins, but these two pins have different spacings from each other. Therefore, an additional adapter 4 can be operated using this side of rod 8, which allows, for example, a smaller workpiece 1 to be connected to the additional adapter 4.

[0053] In the middle of the clamping member, a notch is formed on the side of the clamping member 9 opposite to the recess. The spindle region 12 of the machine tool component 13 can be at least partially inserted into this notch so as to clamp the clamping member 9 on the spindle region 12, and further clamp the workpiece 1 connected by the adapter 4 clamped on the clamping member 9. Preferably, the notch is constructed as a cylindrical hole, and the spindle region 12 is tapered to form a line contact.

[0054] Preferably, the machining machine is a grinding machine. The workpiece 1 is implemented as a shaft and is subjected to external cylindrical grinding on the machine tool after the workpiece 1 is clamped.

[0055] The rod 8 is only configured as a tool for screwing the adapter 4 into the threaded hole of the workpiece 1 and can be removed afterward.

[0056] like Figure 2 and Figure 3 As shown, the threaded pin 10 is still manipulated after assembly, thus centering and orienting the adapter 4 relative to the clamping member 9.

[0057] like Figure 4 As shown, the mandrel region 12 extends at least partially into the cylindrical recess, thereby causing the tapered mandrel region 12 to contact the edge line of the recess.

[0058] like Figure 7 As shown, an axially protruding connecting strip region 70 is constructed on the side of the clamping member 9 facing the workpiece 1. The connecting strip region is finely machined and abuts against the finely machined end face of the workpiece 1. Therefore, the clamping member 9 is oriented relative to the workpiece 1.

[0059] The connecting strip regions 70 extend more in the circumferential direction than in the radial direction. Preferably, the connecting strip regions are constructed as annular segments. In particular, the radial extension of the connecting strip regions 70 is less than its circumferential extension. The axial extension of the connecting strip regions 70 is less than its extensions in both the circumferential and radial directions. The connecting strip regions 70 are spaced apart from each other in the circumferential direction, particularly uniformly.

[0060] In other embodiments of the invention, the workpiece is implemented as a toothed component for a transmission device, wherein the teeth are ground after the workpiece 1 is clamped onto the mandrel.
