Definitions

  • This invention relates to a method of straightening a 5 deformed frame element of a vehicle body, comprising anchoring the vehicle body to a substantially horizontal straightening bed at a plurality of selected anchoring points on the vehicle body, applying a straightening force to at least one force-application point on the frame element 10 to be straightened, and applying to at least one further anchoring point on the vehicle body a bracing force opposing the straightening force.
  • the invention also relates to apparatus for straightenin a deformed frame element of a vehicle body anchored to a 15 substantially horizontal straightening bed at a plurality of selected anchoring points on the vehicle body, com ⁇ prising force-application means for applying a straighte- ' ning force to at least one force application point on the frame element to be straightened, and bracing means for 20 applying a bracing force opposing the straightening force to a further anchoring point on the vehicle body.
  • anchoring elements When straightening damaged vehicle bodies, parti ⁇ cularly self-supporting automobile bodies, it is common 25 practice to secure the body to a horizontal straightening bed by means of suitable anchoring elements at a plurality of, e.g. four, anchoring points on the body, usually on the underside of the body.
  • the anchoring points often are
  • bracing means e.g. in the form of chains, are often applied to take up the straightening force and thereby prevent the body from becoming displaced 35 under the action of the force applied to straighten the deformed frame element.
  • Such bracing means are shown e.g. in U.S. Patent No. 3 590 623.
  • the object of the invention is to provide a method and apparatus of the kind indicated with which the danger of "overpull” is eliminated or at least greatly reduced. This object is achieved with the method defined in claim 1 and the apparatus defined in claim 6.
  • Fig. 1 is a diagrammatic plan view illustrating the anchoring of a vehicle body to a straightening bed in accordance with the invention
  • Fig. 2 is a side elevation showing a device embodying the invention ?
  • Fig. 3 shows the device of Fig. 2 viewed from line III-III;
  • Fig. 4 is a fragmentary sectional view on line IV-IV of Fig. 3.
  • Fig. 1 shows a horizontal straightening bed resting on a workshop floor, a platform or the like and com- prising a frame 1 constructed from two longitudinal beams 2 and 3 and four cross-beams 4 to .7 rigidly se ⁇ cured to the longitudinal beams.
  • Two additional cross-beams 8 and 9 are displaceable along the frame 1 on the upper side thereof and adapted to be secured in position with respect to the beams 2 and 3 by means of suitable re ⁇ taining assemblies 10 to 13, e.g. comprising washers, bolts and nuts.
  • Each beam 8 and 9 carries two slidable anchors 14, 15 and 16, 17, e.g. in the form of conventional clamps, which are adapted to be secured in position on the beams.
  • the anchors 14 to 17 are adapted to be secured to four selected anchoring points 18 to 21 on the body sills 22 of an automobile body indicated by a broken line at 23 and including a deformed frame portion to be straightened.
  • the part of the body that has been deformed is only shown as an elongated frame element 24.
  • the beams of the frame 1 and the longitudinally displaceable cross-beams 8 and 9 preferably are of the type shown in Fig. 1 of U.S. Patent No. 4,023,394, i.e. they are each provided with a continuous central longi ⁇ tudinal slot. Such slots provide for a convenient connection of the beams 8 and 9 with the frame 1 and for attachment of frame anchors, straightening apparatus and other devices to the beams.
  • a conventional pull straightening device 25 such as a hydraulic jack, is detachably secured to the beam 7 and conventionally connected through a force-transmitting element in the form of a chain 26 with one end 27 of the deformed frame element 24 to be straightened. Since the pull straightening device 25 with the chain 26 is con ⁇ ventional and well known in the art, a detailed descrip ⁇ tion thereof is omitted here.
  • a third cross-beam 28 is displaceable along the upper side of the straightening bed 1.
  • Cross-beam 28 is adapted to be secured in selected positions on the beams 2 and 3 by suitable retaining assemblies 29, 30, e.g. formed by washers, bolts and nuts, and is provided with a central longitudinal slot 31 similar to the above- mentioned slots of the other beams.
  • a brace 32 secured in position on cross-beam 28 is clamped to the frame ele ⁇ ment 24 at an area 24a thereof where the deformed frame element portion ends.
  • Brace 32 is illustrated in greater detail in Figs. 2 to 4; for illustrative purposes Fig. 1 only sTiows a locking collar 33 forming part of the brace 32.
  • Three anchoring members 34 to 36 anchor the locking collar 33 to the beams 3 and 28 and thus indirectly to the frame 1 so that the anchoring point formed by the area 24 ⁇
  • OM is omnidirectionally braced.
  • the anchoring members 34 to 36 comprise two chains 34 and 35 and a bracing rod 36.
  • One end of each of the chains 34 and 35 is connected to a stud bolt 37 and 38, 5 respectively, on the locking collar 33, while the other end is connected to a hook 39 and 40, respectively, near the end of cross-beam 28. Since the details of the hooks 39, 40 form no part of the invention, they are not illustrated.

  • the automobile body 23 With reference to Fig. 1, the automobile body 23
  • the body 23 is also secured to the straightening bed at a fifth anchoring point located at a selected area 24a of the frame element 24 which area separates the deformed portion of the frame element from the un-

  • the straightening device 25 may exert a very great pulling force on the frame element 24 without the effect of the force being extended beyond the anchoring point at the area 24a, i.e. without causing the undamaged portion of the frame element 24 to become distorted.
  • the brace 32 is illustrated in greater detail in Figs. 2 to 4. For illustrative purposes the chains 34 and 35 and the bracing rod 36 are omitted.
  • the locking collar 33 en ⁇ closes a screw-threaded vertical spindle 42 which is rotatable about its longitudinal axis.
  • the spindle 42 extends through the slot 31 in cross-beam 28 and is clamped to the cross-beam by a retaining assembly com ⁇ prising two nuts 43, 44 and washers 45, 46.
  • a slot 47 is formed at the upper end of the spindle 42, and in the slot a bracket in the form of a clamping jaw 48 is pivotally mounted on a pin 49 extending transversely through the spindle 42.
  • Spindle 42 thus serves as a clamping jaw support which can be selectively secured in position on the beam 28.
  • Clamping jaw 48 is provided with a toothed segment 50, the teeth 51 of which may be engaged with the locking collar 33 at a recess 52. in the upper side of the locking collar to retain the clamping jaw in a selected angular position thereof, see Fig. 4. Tightening of a lock nut

  • No. 1 Cross-beam 28 is movable by displacing it parallel to itself along the straightening bed 1.
  • No. 2 Spindle (support member) 42 is movable along the slot 31 longitudinally of beam 28.
  • Clamping jaws 48 and 55 are jointly pivotable about pivot pin 49.
  • Clamping jaw 55 is movable from the position shown in Fig. 3 in which the vice formed by the clamping jaws 48, 55 has its clamping faces in a vertical plane, to a position on top of jaw 48 in which the clamping jaws form a vice having its clamping faces in a plane perpen ⁇ dicular to the first-mentioned plane.

Abstract

Dans un procédé et appareil de redressage d'un élément déformé (24) du châssis de la carrosserie d'un véhicule (23), la carrosserie du véhicule (23) est fixée à un lit horizontal de redressage (1) à quatre points sélectionnés de fixation (18 à 24), situés de préférence sur les longerons (22) de la carrosserie, et à un point supplémentaire de fixation situé à un endroit (24a) de l'élément (24a) du châssis adjacent à la déformation, par un étau multidirectionnel (32). La fixation à ce point supplémentaire de fixation (24a) est réalisée par une patte de fixation montée sur un organe de support et comprenant deux mâchoires de serrage (48, 55). L'organe de support (42) peut être déplacé jusqu'à une position sélectionnée en coulissant le long d'une fente pratiquée dans une poutre (28) montée de façon mobile sur le lit de redressage (1), et peut être fixé dans la position sélectionnée. L'action de redressage est effectuée en fixant un collier (33) porté par l'organe de support (42) à la poutre (28) par l'intermédiaire d'une paire de chaînes (34, 35), et à une autre poutre (3) du lit de redressage (1) par l'intermédiaire d'une barre de redressage (36).
