Description

[Detailed description of the invention]

FIELD OF THE INVENTION The present invention relates to a vehicle body measurement system of novelty that represents a clear and substantial advance over the currently known state of the art. The present invention relates to a system that makes it possible to correct distortions of deformed structures by determining and establishing the control points of a vehicle that has encountered an accident according to criteria set in a commercially available model.

[0002] In recent years, the systems proposed for this purpose generally consist of a longitudinal beam and several movable transverse arms sliding on the sides of said beam. Each of the arms has an extending pointer carriage, on which is arranged a longitudinally extending pointer with a pointer head in each case, so that the beam is aligned in series with the longitudinal direction of the vehicle, based on the technical data corresponding to the vehicle in question. and slide the longitudinal extension pointers to the points set in the data, and place some of the longitudinal extension points on undamaged parts of the vehicle. These are used as references to correct distortions in damaged areas until the vehicle's reference point is set in the correct position so that the structure and body of the vehicle are perfectly balanced.

[0003] This system has the following drawbacks, for example. That is, when installing extension arms on the sides of the central beam, some of the arms will experience a certain deflection due to end overload, which will exert a torsional effect on the central beam, causing it to bend in the horizontal and vertical planes. may result in distortion of the measurement at the point.

[Problems to be Solved by the Invention] The purpose of this system is to solve the above problems.

[Means for Solving the Problems] The present invention provides a structure of a longitudinal beam with a transverse beam across the top of the beam, including a sliding member and a suitable braking member, that is, the installation method and the reinforcement of the arm ensure that This is possible due to the condition that torsional movements on the main beam are avoided and deformations at the installation point are also avoided.

On the other hand, in the conventional system, the lateral measurement of each point must always be made from the starting point "0" corresponding to the axis of the beam, but in the system of the present invention, the plate carrying the longitudinal extension pointer is Since it can slide from one end of the beam to the other, it can be measured independently of the aforementioned "0" point.

[Embodiments] Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings. As will be apparent from detailed reference to the drawings, particularly FIG.
Parallel lateral beams 1 of books are arranged and connected by separators 2 placed at the ends and at several points in between. On the outside of said transverse beam a graduated gauge 3 is provided, at the top a guide 4 on which several transverse arms 5 with graduated gauges 6 on the sides slide, and on the bottom is provided with a sensor 7 facing the gauge 3 of the lateral beam 1, so that said lateral arm 6 is located in a perfectly defined position throughout the entire length of the beam formed by the lateral beam 1 and is fitted with appropriate braking elements. It can stay in the installed position via.

On the other hand, an extension pointer support plate 8 is mounted above each horizontal arm 5. On this board, the extension pointer 9
can slide along the entire length of the arm 8 with the sensor 10 facing the corresponding gauge 6 on the lower side, so that the extension pointer 9 can be completely positioned above the reference point set by the manufacturer for each vehicle. It is possible to position the Therefore, from several positions of the extension points up to the reference point of the undamaged vehicle, all further extension guidelines can be set according to the correct measurements specified in the technical data of the vehicle. The parts that have encountered an accident are straightened until the point corresponding to the structure of the vehicle is at the point determined by this measuring gauge. The gauge is arranged to be suspended without the use of a lift.

FIG. 2 is a cross-sectional view of a set constructed by the present system, in which the heads of the two beams 1 form a main beam connected by a separator 2 and assemble a solid beam structure by screws 11. It is shown. The outer side of each beam 1 has a groove 12 for attaching a calibrated gauge 3 and a cutout 13 having an appropriate cross section for accommodating a guide rail for a pointer or sensor 7 attached to the transverse arm 5. The arm can be positioned on the beam according to the measurement point determined by measuring in the longitudinal direction of the gauge 3 for the beam.

The tops of both side beams 1 are provided with integrally mounted rails of suitable cross-section, the sides of which are provided with cylindrical guides 15 of suitable material, suitably grooved.
is provided, on which a grooved wheel 16 slides. This wheel is mounted by an axis perpendicular to the base 17 of each of the transverse arms 5 and is centrally located on both sides of said base 17 and the longitudinal beam or angle 18, and is mounted on said angle 18. A corresponding pointer 7 attached to a guide 14 is provided.

The bottom of each one of the bases 17 of the transverse arms 5 is provided on both sides with grooves 19 for incorporating clamps 20 aligned with the cylindrical sliding guides 15. Said sliding guide 15 is pierced by a tapped rod 21 into which a tension spring 22 is inserted, the rod 21 extending outside a corresponding base 17 for receiving a drive throttle 23 to select the position of the arm 5. and guide 1
5 forms a mechanism for braking the arm 5. That is, the action of tightening the throttle 23 causes the rod 21 to set the clamp 20 closer to the guide 15 to achieve a braking action. On the other hand, when the throttle 23 is released, the spring 22 separates the clamp 20 and the corresponding arm 5 is released.

FIG. 3 shows the position of the arm 5, seen from the end, located on the top of the beam formed by the side beams, which arm is attached to the base plate 1 by means of screws. Said arm 5 has above it a guide 25 having the same characteristics as the guide of the beam 1 and is provided with a corresponding guide 26 through which the grooved wheel 2 is attached to the plate 8.
7 slides along the longitudinal axis carrying a longitudinal extension pointer 9. This vertical extension pointer slides the plate 8 along the arm 5,
It is designed to be placed at the corresponding reference point by installing in a manner similar to the method described above for installing the arms on the lateral beams 1 of the longitudinal beams. However, in FIGS. 2 and 3, only the throttle 23a is shown.

On both sides of the profile formed by each of the transverse arms 5, a slightly elongated groove 28 is provided for incorporating a calibrated gauge 6, whereby a plate with an extension pointer 9 is provided on the basis of the determined value. 8 precise positions can be measured. Similarly, two spigots 29 are provided, through which the guide 30 slides. The guide 30 is attached to a pointer with a sensor 10 which is connected to the plate carrying the extension pointer 9 by means of a trapezoidal profile strap 31 which is connected to the plate 8 by screws 32. The purpose of the strap is to hold the pointer 10 in the operating position, and also allows the corresponding plate 8 to be removed at will once it is in place.
