Definitions

  • the invention relates to a receiving device for a Tool for reshaping body components according to the Preamble of claim 1 and correspondingly suitable Tools for reshaping body components.
  • Damage is due to the deformation of one Body component, the damage is remedied by means of special recovery tools with which in the Essentially the original condition by applying Tractive forces in the area of the damaged body component is restored.
  • a holding element or depending on Damage size and / or structure a number of Holding elements at previously selected locations on the maintenance setting body component, in particular by gluing or Welding attached to subsequently using Recovery tools defined tensile forces on the Apply holding elements. After the damage is repaired these holding elements mostly by applying a torque detached from the body component and then remains of the fasteners used, such as adhesive and / or welding residues removed from the body component.
  • those of the body component to be re-deformed Holding elements essentially by screw connections or also releasably connected to the reshaping tool, these holding elements in the form of washers and / or are designed like pins or bolts. He follows fastening by welding, these are the holding elements moreover, generally trained in such a way that they are considered Electrode can be used. Although they are detachable Screw connections between the holding element and one Recording device or the reshaping tool for Shortening individual work cycles by the possible Exchange of the holding elements already useful.
  • An object of the invention is therefore a Recovery device for recovery tools to provide a much more flexible handling in Terms of the reshaping process itself as well regarding the connection between the Recovery tool and the holding element allows.
  • an object of the invention is to design the receiving device such that a Connect and disconnect between the holding element and Recovery tool essentially anytime and regardless of the location of the recoverable Body component is ensured, essentially a variety of, in particular designed as an electrode Holding elements largely independent of the type of Recovery tool can be used.
  • Training device with a housing which for the insertion of a holding element essentially shaft-shaped or bolt-like area Receiving opening includes, being within the receiving opening a self-locking clamping device to provide a non-positive connection arranged with the holding element and is connected to the clamping device Unlocking device is provided.
  • the particular advantage here is that due to the self-locking arranged in the receiving opening Clamping device essentially solely by inserting the Holding element a quick compared to the prior art and much easier fixation both for transmission tensile forces and torques for loosening or Tear off the holding element from a body component is guaranteed.
  • the Closing device interacting safety device ensures that the recovery tool itself from the holding element back to quick and very simple Way can be removed without removing the holding element from to have to loosen the body component. As a result, Essentially all different types of Recovery processes supported effectively.
  • the clamping device at least one, but expediently at least two Comprises clamping jaws which are arranged so as to be movable, that they are between the introduced area of the holding element and an inner wall extend the receiving opening.
  • the movably arranged Clamping jaws are wedge-shaped and / or the Diameter of the receiving opening in the insertion area the insertion direction of the holding element tapers like a funnel, so that I inserted the Clamping device self-locking between the inserted Extends the region of the holding element and the inner wall. This will inadvertently loosen the holding element from the cradle even when applying larger Tractive forces essentially completely excluded.
  • the clamping device for Self-locking in the receiving opening to be arranged so that the clamping device essentially is always exposed to a restoring force by which it is used Taking a predefined state is driven.
  • the invention also looks expedient before that related to the clamping device Unlocking device along the axis of the Arrange receptacle slidably on the housing that unlocking the clamping device as a result of Moving the safety device in the direction of insertion of the holding element takes place.
  • the safety device in the form of a housing partially encompassing socket formed on an im Insertion area extending part, in particular the Clamping jaws of the clamping device are present.
  • the receiving device according to the invention is advantageously with a number already today used recovery tools connectable.
  • the device according to the invention is provided to connect with a pull hook, for example in form an eyelet at the rear end of the housing, train.
  • a pull hook for example in form an eyelet at the rear end of the housing, train.
  • connection elements for example to connect to a actuator that can be placed on a body part as they are in particular in the international patent application PCT / DE 99/02908 is described.
  • the invention Cradle also at one end of a tie rod can be arranged, with a motor-operated Traction device the tensile forces are applied.
  • a such a tool is for example in EP-B-0 640 415 disclosed.
  • FIG. 1 in cross-sectional representation a first embodiment represents the recording device according to the invention.
  • the Insertion area 3 is opposite to the insertion direction A. is funnel-shaped.
  • a spring 6 held under pretension arranged inside the essentially cylindrical opening 2 .
  • the outer diameter of the sleeve 5 is smaller than the inside diameter of the opening 2 so that the sleeve is a Ensures slide function.
  • the dimensions of the Clamping jaws 4a and 4b are predefined in such a way that this in the insertion area 3 in the through opening 2 in Are caught essentially axially movable and a complete emergence by the in the insertion area 3 tapering funnel of the opening 2 is prevented.
  • Termination unit 8 is a for biasing the spring 6
  • Investment area 9 ready according to the present Embodiment for improved positional fixation of the spring 6 in the form of a bore for receiving a portion of the Spring is provided. Accordingly, this takes on Section opposite side of the spring 6 one on the Sleeve 5 provided contact surface 10, the spring 6.
  • the spring 6 exerts the socket 5 has a substantially uniform force on the two jaws 4a and 4b.
  • Radially outward inclined End faces 5a and 5b of the sleeve 5 also ensure that the jaws 4a and 4b along the inner wall of the Through opening 2 are guided and in so far a Tilting and / or wedging of the clamping jaws 4a and 4b is prevented.
  • a sleeve 11 is in the direction of arrow A over the Housing 1 slipped and in the present embodiment by means of an O-ring 12 which is in a groove in the housing 1 sits in the area of one on the inner wall of the sleeve 11 trained undercut 13 in the axial direction slidably arranged, the sleeve by application a sufficiently large tractive force can be released from the housing can.
  • the sleeve 11 is designed such that one with a Bore 14 provided collar 15 on the jaws 4a and 4b is applied.
  • FIG. 2 One for the receiving device according to the invention a suitable holding element is exemplified in FIG. 2 outlined.
  • a holding element comprises a head part 20 on which a shaft or bolt-like section 21 for Insertion in the insertion area 3 of the receiving device 1 is formed.
  • the shown in Fig. 2 Holding element also has a small tip 22, which when welding to attach the holding element to a the capacitor discharge to be reshaped controls.
  • the maximum insertion depth of such a holding element can also about the choice of dimensions of the sleeve head 16, on which the head part 20 of the holding element at Introduce comes to the plant, be specified.
  • the jaws 4a and 4b are the 1 in a practical manner provided with a thread 17, which when a Torque from the cradle to a to be reshaped body part fastened holding element a further improved frictional connection between Holding element and holding device for tearing or loosening of the holding element leads from the body part.
  • the sleeve 11 For releasing the holding element from the receiving device the sleeve 11 is moved in the insertion direction, whereby the Clamping jaws 4a and 4b are displaced inwards into opening 2 and release the holding element in succession.
  • the embodiment shown in Fig. 1 also has one arranged on the termination unit 8 Connection device 18, which for connecting to a Recovery tool, which has draw hooks, especially suitable is.
  • a Recovery tool which has draw hooks, especially suitable is.
  • One such also known as a pulling claw
