Definitions

the invention relates to a method for positioning attachments and extensions to the large sections of a modular rail vehicle, the large sections being assembled from individual parts according to a dimensional reference system with tactile dimensional reference points and then being expanded at least on one side with further equipment parts, and it is particularly advantageous applicable when removing the base module of a local rail vehicle.
DE-OS 42 16 606 proposed a method by which the large sections were already made during production with several probable and high Precision reference points to be arranged.
gauges or templates are not only two-dimensional, but also three-dimensional, so that sometimes their storage near the stage of expansion of the large section can also be problematic for reasons of space.
the invention thus pursues the goal of designing the positioning of attachments and extensions on the large sections of a modular rail vehicle in such a way that the aforementioned deficiencies in the prior art are eliminated.
the object of the invention is to devise a method for positioning attachments and extensions to the large sections of a modular rail vehicle, which, based on existing reference points, avoids time-consuming and inaccurate measurement and marking by hand and the expenditure for special gauges or stencils can be reduced to a minimum.
the object is achieved with a generic method according to the preamble of claim 1 according to the invention in such a way that the dimensional reference points first with passive reflectors or active sensors, then a laser projector is pre-positioned according to the reference points on the large section and then the exact position of the laser projector is determined with respect to the projection surface by controlling the reflectors or sensors on the reference points.
a first image created in a CAD system is called up from the memory of a control computer, transferred to the laser projector and projected from there onto the large section on a scale of 1: 1. Finally, the projected image is marked on the large section and / or incorporated into it, and the next image is called up from the memory of the control computer by remote control. After the completion of the large section, the projection and identification of the positions of the connection modules with subsequent arrangement and connection of the modules to one another is then carried out. Appropriate embodiments of the method according to the invention are specified in subclaims 2 to 6.
the advantage of the method according to the invention over the prior art is that an immediate display of the positions of the components in the assembly process of the large sections is possible directly on the basis of a CAD assembly drawing without complex measurements and without special gauges or templates. By eliminating any measuring processes, enormous time savings can be achieved, and incorrectly placed bores or positions due to errors in the dimension calculation are completely eliminated with the method according to the invention.
Another advantage of the method according to the invention is that all projected bores and positions have a uniform, neutral dimension reference and body parts that are subject to high tolerances, such as the headpiece or longitudinal beam edge of the underframe, are replaced by reference axes drawn between the dimension reference points. This can significantly improve the accuracy of the holes or positions, especially among each other, and accelerate the expansion of the large sections into modules.
the method according to the invention offers the possibility of not only displaying bores, openings and positions precisely, but also the position of components, benches, partitions, pipe clamps, sliding blocks and the like. Like. or to project the course of cable runs and / or of pneumatic / hydraulic lines on the individual large sections.
this is a significant increase labor productivity while ensuring very good quality. Details of the invention will be explained in more detail with reference to the accompanying drawing.
the drawing shows the schematic representation of an underframe module of a commuter rail vehicle inserted in a device, on which the removal parts are positioned using the method according to the invention.
the assembly of the underframe, which forms a large section 5, from individual parts is carried out in a known manner in a device 8, preferably on the main cross members and the side longitudinal members of the underframe, a series of neutral reference points 6 only indicated in the drawing in the form of probable bolts with high accuracy according to a Dimension reference system can be arranged.
the underframe remains in the device 8 in the example shown, and the dimensional reference points 6 are first equipped with passive reflectors or active sensors. Then one or more laser projectors 1 are prepositioned according to the reference points 6 on the large section 5 and the exact position determination of the laser projector 1 with respect to the projection surface 3 by controlling the reflectors or sensors on the reference points 6.
the prepositioning is preferably carried out by manual or mechanical approximation of the Laser projectors 1 arranged on slide rails or portals to the intended reference points 6, and the exact position determination is preferably implemented automatically by a calibration unit integrated in the laser projector 1 by searching with a laser beam for reference points 6 arranged within the projection surface 3, at which the laser projector 1 is located can orient.
a calibration unit integrated in the laser projector 1 by searching with a laser beam for reference points 6 arranged within the projection surface 3, at which the laser projector 1 is located can orient.
reflectors or sensors on the reference points 6 also depends on whether the calibration unit of the laser projector 1 is able to recognize the laser beam reflected by the reflectors as a positioning signal or whether the positioning signal from active sensors that are hit by the laser beam and wired to the laser projector.
the exact positioning must be ensured by appropriate aids, for example by stops on the portals or slide rails which the laser projectors are arranged can be realized.
the first figure 4 created in a CAD system is called up from the memory of a control computer 2 and this figure 4 is transferred to the laser projector 1.
the data for generating the projected figures 4 can also be used alternatively, they can be generated via the so-called teach-in mode, in which the image 4 to be displayed is scanned once in a punctiform manner and can then be called up as often as desired.
the transfer of CAB data and drawings is simpler, it being possible in a particularly advantageous manner to split up extensive drawings and to display the respective contours one after the other.
the projection of Figure 4 onto the large section 5 on a scale of 1: 1 is carried out by means of the laser projector 1, the precise vertical radiation of Figure 4, the flatness of the projection surface 3 as well as the roughness and / or the color of the surface being decisive for are an optimal quality of the projection.
Another factor influencing the quality of the projection is the distance of the laser projector 1 from the projection surface 3, the minimum of which can be calculated from the maximum beam angle of the laser projector 1 and the edge length of the surface to be irradiated.
the large section 5 can be expanded in different planes either in the simplest manner, with the laser projector in the same position, by changing the projected scale or by a three-dimensional projection, or in a conventional manner by adjusting the height of the laser projector 1 and / or the device 8 .
the projected image 4 is then marked and / or incorporated into the large section 5, which is preferably done by punching and / or drilling a hole pattern or a position, but also, at least when marking, in a variety of other ways , for example with light-sensitive layers of color on the large section 5, can be realized.
