    Device for rail processing by means of controlled tracking of the processing tools
    The invention relates to a device for rail processing, in which the processing tools are tracked as accurately as possible to the rail profile in order to achieve an optimal result in the post-processing.
    Such a device is described in claim 1 and the other dependent claims.
    The rail processing for laid railway or underground rails is such. mentioned in the patents EP 0952255 A1. In general, the objectives are defined in all rail machining so that at the same time a maximum removal of flaws or cracks depending on the rail condition at the lowest possible material removal, and the best possible surface quality or dimensional accuracy in relation to the longitudinal or transverse profile can be achieved. Grinding applications here are more in the range of low removal rates, milling more in the range of larger delivery depths represented. The requirements in terms of machining accuracy and surface quality are always higher, especially in view of the low noise of the moving train due to the rolling noise to be minimized. This presents advanced and new challenges for the machining methods, especially with regard to the track tracking of the machining tools, in order to meet the above requirements.
    Among other things, the milling technology has proposed a face milling technology as described in patent AT508756B1 as a solution for increasing the surface quality, in particular in the area of the driving mirror. As explained in this patent, the use of multiple end mills, although an improvement in the surface finish, but is due to the supported on the opposite side of the rail head guide rolles, as described for example in US 4583893 A, consuming or may be uneven with respect to successively arranged milling cutters and their milling patterns. In general, the exact positioning and orientation of the milling tool to the rail both in the longitudinal direction and in the transverse direction of the rail to adjust exactly to avoid a processing offset in relation to the longitudinal or transverse profile of the rail due to the low feed depths in finishing applications. Here are the spatial orientation of the rail on the one hand and the necessary lane play of the towing vehicles and torsion of the vehicle frame and different
    Bending of the rail depending on the substructure or axle loads on the other hand as problems to be solved.
    The prior art is that the milling devices on the rail vehicle as described in the patent DE 32222208 A1 attached via a pivot bar with pivot pin on the chassis, laterally guided over guide rollers of the rail and vertically supported by a liftable and sliding shoe associated with the rail. The tracking takes place here with a rotational movement about the pivot in the longitudinal direction and vertically arranged pivot points in the transverse direction of the rail - ie in two mutually perpendicular planes.
    Furthermore, the prior art that, as described in the patent EP 0952255 A1, via a cross slide, consisting of a vertically guided carriage for height adjustment of the milling housing and a horizontally guided carriage for the lateral displacement of the milling housing, the adjustment is achieved. Further, the prior art in these patents is described in that the milling units are rail independent, i. in each case based on the position of the individual rails copying, that is on leadership roles, are forced. It has also been proposed in the patent EP 0952255 A1 that the housing is supported to the rail by means of a side cheek pivotally mounted coaxially with the milling cutter head.
    In total, according to the current state of the art usually two to max. three degrees of freedom in the spatial positioning or orientation to the rail covered. Due to the position of the processing tools in relation to the rail vehicle, in particular to the bogies or rigid axles, it comes just when cornering to incorrect positions compared to the laid tracks, especially for small curve radii. An amplification of this effect occurs especially in milling units, which are not located centrally between the bogies or axles, since according to the state of the art, the milling units can perform neither an angular compensation in the vertical direction and an angular compensation in the transverse direction. This also applies to the device described in the patent DE 3222208 A1, which is indeed rotatable about the Gelenkzäpfen and swivel bar, but can not be rotated back to the rail position by missing pivot points on the milling unit. A missing angular compensation in the transverse direction is accepted because of the currently often in use radial milling, since the error is considered low, but must not be neglected by a given cross-section of the rail head. Even more important is this angle compensation in a Stimfrästechnologie, especially in relation to two mating end-milling on the right and left sides of the rail, especially when several milling units arranged one behind the other a 3 ··· * · ♦
    To perform rail processing. Furthermore, it comes in the so-called sinusoidal run of the vehicle by the game between the wheel flanges and the rail head side surfaces of at least 20 mm and the conical wheels to different positions with respect to the altitude and bed position of the vehicle. When driving in elevations and not exactly laid tracks it comes in addition also to torsions of the vehicle frame. This leads to a further undefined starting situation between the vehicle frame, which represents the starting positions of the processing units, and the rail to be processed.
    Another contradictory point in rail tracking is the need for accurate rail tracking while compensating for flaws. Thus, on the one hand, the laid track should be precisely tracked, on the other hand, flaws such. Flattening points (wave-shaped depressions on the rail running surface), rail joints or deformations are to be leveled out. In the already mentioned patents, forced guides, i. Guide rollers used for track management, which translate the error points copying into the milling result, which is not desirable.
    The aim of the present invention is to solve these stated disadvantages of the existing systems and the associated problems in the rail processing and to provide a device that can ensure optimum rail processing with at least four degrees of freedom by a controlled tracking of the processing tools.
    The device according to the invention is described below with reference to several examples and is characterized by claim 1 and the following claims.
    In a preferred embodiment variant of the processing device according to the invention, a combined rail height and side offset pivots with two measurement points offset in the longitudinal direction via e.g. hydraulic cylinders or via e.g. Hydraulic or electric rotary drive about a pivot point from a first mounting plate to the effect until the two consecutively arranged measuring points of the page copy in a predetermined tolerance range have the same measurement results for rail inner edge. The measuring points are arranged symmetrically to the processing unit and thus rotate the orientation of the
    Machining tool for the necessary symmetrical orientation with respect to the rail profile according to. The lateral adjustment to the rail and the vertical adjustment to the rail head are realized here per rail via a cross slide.
    The machining tools are preferably mechanical, abrasive tools, such as milling tools or grinding tools, preferably milling tools. Furthermore, on the average measurement results of each of the two tracks associated height adjustment on one on the already twisted
    Fixing plate rotatably mounted second mounting plate, the orientation with respect to the altitude of the rails to each other readjusted until the measurement results of the Höhenkopierung between the left and the right rail are equal again in a predetermined tolerance range. Through these two new rotational movements, the processing units are now oriented towards the rail and are employed on the linear axes of the cross slide for rail head side surface or rail head surface, wherein the damping shoe rests and the actual processing unit to the rail of height in each case based on the diameter of the Machining tool coordinated retreat altitude is located. This return height position is chosen so that in normal operation no collisions with a defined clearance gauge is given. In order to enable the mountain or trough travel as well as a track deflection compensation, the processing unit is arranged via a further pivot point so that the alignment takes place in the longitudinal direction of the rail by the overlying damping shoe or support shoe. The feed movement and thus Abtragstiefeneinstellung via an additional vertical linear axis between the actual processing unit and the damping or support shoe. Through this feed movement, the processing depth is infinitely adjustable and can thus be used for roughing or finishing applications or targeted removal. The actual processing unit can thus, based on the damping or support shoe, from the withdrawal height to the max. Move the feed depth vertically.
    As a result of this possibility, a maximum milling cutter geometry, depending on the clearance profile, can be used in the case of several processing tools arranged one behind the other. Depending on the interference geometry, the respective machining tool is lowered for machining or raised in the retracted position. This allows for processing without interference contour to bring larger processing tools to use and thus to achieve longer life and, at the same time in tight spaces with small
    Machining tools to perform the processing. It should be particularly noted that according to the invention, only the processing units depending on the circumstances hire or withdraw, but the measuring systems or the shoe remains employed on the rail. The return movement or setting movement here can be between e.g. two milling units are controlled in such a way that the new milling unit to be set up starts the machining on a flat ramp and after a short simultaneous, overlapping machining, the returning milling unit with a likewise flat ramp terminates the machining by a return movement.

    As a coordinate system, an X, Y, Z coordinate system is set up, wherein X along the rails, Y perpendicular to the plane of the laid rails normal to these and Z normally rises in height. Rotation about X (30) thus means a rotation about a parallel to the rail, rotation about Y (31) a rotation parallel to the axis of a rail vehicle and rotation about Z (32) means a turning from the direction of travel, or normal thereto.
    This coordinate system is used for ease of understanding and refers to the axes as described, with each deviation of the axes by +/- 10 ° can result from the combination of movement in multiple axes. Thus, for example, a movement along Z means that the movement is from top to bottom or bottom to top in a cone with 10 ° opening angle; thus not strictly normal, but each can be done at an angle between 80 and 100 °. This deviation of 10 ° results from the curve and angle of the rails (2) and will not be mentioned separately in the following to ensure better readability of the description.
    By means of the device according to the invention, a plurality of degrees of freedom can each be covered and utilized for tracking along the individual rail (2), that is to say each rail (2) can be followed independently of the other one. At least 4 degrees of freedom, preferably the two axes of rotation about the X (30) and the Z axis (32) and the two linear axes Y and the Z axis are covered. Furthermore, with the device according to the invention in further embodiments, the rotation about the Y-axis (31) and also an additional linear movement in X can be controlled.
    This succession can be done on the one hand on the principle of an industrial robot, preferably a articulated robot, on the other hand, by other suitable combinations of linear and rotary movements.
    The movements for the two rail tracks (2) can also be combined via a mounting plate (10, 15), in particular if the general rail quality can be improved in the interaction of the left and right rails (2).
    In the further embodiment, the background of the necessary tracking of the rail (2) leads mentioned and described solutions with coupling of two movements respectively for the right and left rail (2).
    As can be seen in Figures 1, 2 and 3 are due to the under a rail vehicle (4) in spatially undefined position rail tracks (2) accurate readjustment to the rail (2) only over 6 degrees of freedom possible. The first degree of freedom is often covered by the vehicle movement along the X direction. 9 ΦΦ · ΦΦ Φ · ΦΦ ·· ΦΦΦΦ · «* · * · · Φ Φ · Φ ψ Φ · φφφ ··· I f · φ Φ · Φ Φ Φ Φ Φ φ φ Φ Φ ΦΦ
    As shown in Figure 1, it comes through the support forces of the rail vehicle (4) for deflection of the track (2) and in trough or Kuppenfahrten due to the terrain to a vertical displacement of the track (2) in the Z direction, thus shifting the Rail upper edge (3) under the rail vehicle (4). This vertical displacement is traced by the vertical linear movement in the cross slide (16). As can also be seen in FIG. 1, depending on the positioning of the processing unit (1) in the longitudinal direction with respect to the rail vehicle (4), a rotational movement according to the invention about the Y-axis (31) must be realized in order to produce the processing tools (1), especially in front milling technologies (1a ) to adjust the exact position of the rail (2) in the XZ plane. By the Z-axis of the cross slide (16) the support of the slide shoe (17) on the upper rail edge (3) is possible, wherein the slide shoe (17) can rotate about the pivot point (31) about the Y-axis. By this rotational movement (31) it comes to the angle compensation in the X-Z plane.
    In order to be braced against the cross slide (16) during processing, e.g. a hydraulic cylinder (11) proposed. Another possibility are appropriately dimensioned pneumatic cylinders, but also electric drives. The actual feed movement of the processing unit (1a, 1b) is made possible by an additional adjustment in the Z direction via a further linear axis (24). This linear axis (24) can in turn be moved or set up via a hydraulic cylinder (11), pneumatic cylinder, electrically, or by means of mechanical translation by a spindle drive, or a rack.
    Figure 2 shows a schematic plan view when driving on a straight line. The processing units (1a, 1b) are in their orientation parallel to the rail vehicle (4). As can be seen in Figure 3, when driving in a curve, the processing units (1a, 1b) rotate about the Z axis (32). In Figures 4, 5 several assembly or processing positions in the longitudinal direction (position 1, 2, 3) are given. Depending on the position in the longitudinal direction, in particular to the wheel axles or bogies, there are different necessary deflections (rotation about Z-axis (32)) relative to the rail vehicle (4). The closer the mounting or
    Machining position is located to one of the wheel axles or bogies, the greater is the necessary angle of rotation about the Z-axis (32). This movement is achieved by a rotational movement according to the invention about the Z-axis (32) by means of hydraulic cylinders (11) or via a pivot drive (12), said movement being coupled by the common mounting plate (10) for the left and right rails. The pivot drive (12) can in turn be driven electrically, hydraulically or pneumatically. ·· φ * «« ···· # * 10 • «• φ · · φ φ · · · · · · * * * * Φ ·« φ «φφφφ φφφ ·· ·
    In Figure 6, a rail vehicle (4) is shown with three different mounting positions in a schematic plan view when driving in a curve, here clearly the different rotation of the processing units (1) to the rail vehicle (4) can be seen. Of course, this effect occurs the greater the smaller the radius of curvature of the track strands (2) to be traveled.
    The control principle or measuring system principle for readjusting the rotational movement about the Z-axis (32) is shown schematically in Figures 7, 8 and 9. Basically, after a transfer travel of the rail vehicle (4), in which the processing units (1a, 1b) were moved in a safe retreat position, the rail positions below the rail vehicle (4) determined by a mechanical or optical rail search device. The axes of the cross slide (16) are moved analogously to these determined positions and the measuring systems (20, 22) applied to the rail head (2). The processing units (1a, 1b) are in this case opposite the shoe (17) in the vertical retraction position. About the measurement results of the lateral measuring systems (20), which are offset in the longitudinal direction but each symmetrical to the actual processing point, a rotational movement about the vertical Z-axis (32) is initiated until the measurement results (20) are equal in a predefined tolerance range. The measuring systems (20, 22) can be designed to be scanned so that, for example, with a sliding block (17), the actual position is determined. But it is also possible to perform the measuring systems (20, 22) optically by means of camera detection or laser. Other possibilities for detecting the positions are ultrasonic sensors or capacitive sensors. Since the measuring systems (20, 22) e.g. In a mechanically scanning system on a retracted lowering position, to protect or lower the systems in a still unknown at this time orientation of the rail (2), and have a fixed measuring range, in addition to the rotational movement (32) and analog adjustment of the Cross slide (16) in the Y direction. In this case, the average measurement result is used as the traversing speed indicator between the front and rear measuring system (20) as the control value, and the measured value of the page copy closer to the fulcrum (32) is used as the starting value. The rotational movement (32) is e.g. implemented via hydraulic cylinder (11) or a pivot drive (12).
    In figure 7 this starting position is reached.
    Figure 8 shows a first minimum rotational movement about the Z axis (32) when entering a curve. Since the measurement results deviate upon reaching the first curvature in a predetermined tolerance range, there is a rotational movement about the Z axis (32) and simultaneously by the changed average values of the measurement results of the rear and front scanning position and a different value closer to the pivot point ( 32) located to a rotation and a shift until the measurement results of the front and rear measurement points (20) in a predefined tolerance range are the same again and the average value of the measurement results or the closer to the fulcrum (32) located page copy back to the default Normal value. Again, in the illustrated variant, the movement of the right and left sides is coupled via a common attachment plate (10). In order to obtain a more accurate copy position for the point of engagement of the machining tool (1), the introduction of an additional measuring system (20, 22) is as close as possible to
    Machining tool engagement point for adjustment of the cross slide (16) possible. Here, the rotational movement about the Z-axis (32) is further controlled via the front and rear measuring points as described above. The traversing movement in the Y direction takes place purely via the control value or the measurement result of the additional central measuring device (20, 22).
    A further measuring system (20, 22) may also be connected upstream of the processing unit (1) in order to detect large rail defects or impacts, etc., at an early stage. This upstream measuring system (20, 22) can be used for various measures of the processing unit (1). This can be a controlled withdrawal of the processing unit (1), information to the operator, who of course can also control the processing system (1) externally, or an error correction stored in the controller.
    In Figures 10, 11 and 12, the interaction of the displacement in the Y direction and the rotation about the X axis (30) is shown in a ride with a curve elevation. Figure 10 shows the initial situation on the straight track (2). The distance values between the cross slide (16) and the rail top edge (3) for the right and the left rail side (2) are determined using the height adjustment measurement results (18). On the other hand, it is ascertained via the side coverings (20) whether the cross slide (16) is still in the correct position relative to the rail inner edge. If a deviation is detected here, the process in the Y direction occurs. As a result, it can be ensured that the scanning of the vertical copy (22) is in the correct position with respect to the rail top edge. If the measured values of the height adjustment (18) between the right and left rail side (2) are different, the rail vehicle (4) is retracted into an elevation or twisting or twisting of the rail vehicle (4) with respect to the track strands (2). According to the invention, this state is achieved via a pivoting movement about the X-axis about the pivot point (30) by an adjustment of the second attachment plate (15) relative to the first attachment plate (10). This is again by a common mounting plate (15) a coupling between 12 12th
    ·· · · ······ ··· · ♦ right and left side given. The subsequent rotation about the horizontal axis (30) in the X-direction takes place until the measurement results of the height adjustment (18) are equal again in a predefined tolerance range. The rotational movement (30) can in turn in this case e.g. by hydraulic cylinder (11) or a rotary actuator (12).
    Figure 13a shows, by the inventive device and associated accurate tracking of several processing units (1), in particular milling units along the laid track (2), the ability to make several milling units (1a, 1b) so that several cutters arranged one behind the other Edit sections of the rail head (2) so that as far as possible per router (1a) the normal to the cutter axis rail head area is processed and thus a Stimfrästechnologie is used, which has a great advantage with respect to the ripple of the processed rail (2). Figure 13b shows a processing unit (1b) as a radial processing unit with angled working axis.
    Figure 13c shows a radial milling technology (1b) with indexable inserts in several tracks associated with the rail head profile (2). By means of the device according to the invention, it is also possible with this milling technology to compensate for the misalignment to the track (2) that is not currently taken into account and to pass on a more precise roughing contour to the subsequent processing step.
    13d shows an end milling cutter (1a), which is designed analogously to the milling profile of FIG. 13b and which is designed so that the milling cutter axis is rotated relative to the rail center, that the entire pre-machined contour can be smoothed with only one end mill (1a). Particularly in the case of face milling technologies, the positioning and orientation of the milling cutter (1a) relative to the rail profile (2) is of great importance due to the longer cutter engagement, which are achieved by the device according to the invention.
    Figure 13e also shows a face milling technology, with two end milling cutters (1a) on the right and left of the rail (2). This application can be used especially in confined spaces.
    Figure 13f shows a reamer as shown in Figure 13c in the profiled insert embodiment.
    Thus, it is possible with the present invention with at least four degrees of freedom optimal rail tracking of the machining tool (1), thus ensuring optimum rail machining.
