Definitions

  • the subject of the present invention is an apparatus for straightening, that is to say restoring to their original shape, parts of bodywork of motor vehicles, which have suffered deformations as a result of a road accident or impacts of various types.
  • the mechanical apparatuses and devices currently in use for this purpose consist in general of a basic structure, from which extend adjustable bars or chains, which bear at their free end pincers or other equivalent gripping elements, which make it possible to hold the bodywork at the required point.
  • the basic structure is anchored on the platform or ramp on which the vehicle, of which the bodywork needs repair, is fixed; using mechanical or hydraulic means, the part of bodywork held with the pincers is subjected to a pulling or pushing action.
  • pulling or pushing in one direction only can permit the restoration of the original shape of the deformed part of bodywork
  • the operator has to carry out numerous variations of the angle of pushing or pulling by taking steps to move manually the basic structure to which the the relevant pushing or pulling elements are fixed.
  • the straightening of the deformed part of bodywork is achieved by using an articulated mechanical device, which is operated by means of oil-hydraulic cylinders and affords the gripping elements, with which it is equipped, the three movements along the three orthogonal directions and the three rotations about these.
  • an articulated mechanical device which is operated by means of oil-hydraulic cylinders and affords the gripping elements, with which it is equipped, the three movements along the three orthogonal directions and the three rotations about these.
  • the operator is able to hold the deformed framework by means of the gripping element and to restore it to its original position and shape simply by working from a push-button arrangement, which operates the hydraulic commands relating to the different movements.
  • the base on which the device is mounted, is provided with wheels.
  • a platform or ramp on which the vehicle (not shown), of which the bodywork needs repair, is mounted and expediently fixed, is indicated generically by 1.
  • 2 indicates a metal basic structure, which is formed by two robust prismatic bars 2a and 2b, which are arranged essentially in a T shape and mounted on pivoting wheels 3 in order to permit easy movement of the apparatus.
  • the bar 2b is provided with two pairs of hooks 4 (one only shown in the figure), or equivalent means, for anchoring the structure 2 on the ramp 1 by means of fixing screws 5.
  • a tubular support 6 with a vertical axis rises, inside which there engages rotatably the foot 7a of a vertical fork 7, which has horizontal pivots 8 on which a tubular guide 9 is rotatably mounted.
  • the latter can, therefore, rotate in relation to both the vertical axis of tubular support 6 (axis X) and the horizontal axis of the pivots 8 (axis Y).
  • the tubular guide 9 intersects with its longitudinal axis the plane defined by the axes of rotation X and Y and is turned towards the ramp 1 with one of its ends. From the ends of the bar 2a of the base 2, two hydraulic cylinders 10 extend, which converge towards the other end 9a of the tubular guide 9, to which they are connected in an articulated manner by means of the respective piston rods 11. Similarly, the cylinders 10 are connected to the bar 2a in an articulated manner at 12.
  • a prismatic guide 13 is coaxially housed, which is provided with a ring gear 14, on which a rack 15 engages, which is operated by hydraulic cylinders 16, by means of which the prismatic guide 13 can be rotated about its own longitudinal axis.
  • a tubular arm 17 of square cross-section is housed, which is axially slidable inside the prismatic guide 13, to this end being operated by an hydraulic cylinder 18. The arm 17 is thus slidable along the longitudinal axis Z of the tubular guide 9 and rotatable in relation to the same.
  • the tubular arm 17 has an end 17a in the form of a fork, to which a cross journal 20 is connected by means of a pivot 19, which is perpendicular to the axis of the arm 17.
  • Pincers 22 are in turn connected to the cross journal 20 by means of a pivot 21, which is perpendicular to the pivot 19.
  • two hydraulic cylinders 23 are also housed, the piston rods 24 of which are connected in an articulated manner to the cross journal 20.
  • two piston rods 25, which extend from hydraulic cylinders 26 located inside the two jaws of the pincers 22, are also connected in an articulated manner.
  • the apparatus according to the invention is provided with a control panel (not shown) with a push-button arrangement, from which the operator controls both the positioning of the pincers 22 and the angle of pulling or pushing from time to time considered necessary.
  • a control panel not shown
  • a push-button arrangement from which the operator controls both the positioning of the pincers 22 and the angle of pulling or pushing from time to time considered necessary.
  • the operator will achieve the correct positioning of the pincers on the part of bodywork to be straightened whereas, by operating the hydraulic cylinders 16, 23 and 26, he will also vary continuously the angle of pulling or pushing employed by the arm 17, which is made to slide axially by action of the cylinder 18.
  • the gripping ends of the pincers 22 can advantageously be provided with teeth 27 in order better to hold the part of bodywork to be deformed. Furthermore, the pincers 22 can advantageously delimit a space 28, which is suitable for the use and the locking of special tools.
  • the apparatus according to the present invention has a constructional geometry such that it is afforded a great rigidity and capacity for deforming even very resistant frameworks, while retaining very compact dimensions.
