Definitions

  • the invention relates to a clamp or Separating device, especially for removing bearing shells, with two jaws separated by at least one Bolts are braced against each other.
  • the invention is based, devices of the type mentioned in the introduction so that the Device quickly on workpieces of different thicknesses scheduled, separated from these, but also the Time required to tighten the nuts considerably can be reduced.
  • the depressions are expediently designed in such a way that they only extend over part of the circumference of the screw bolts. If the locking element is elastically resiliently mounted under these conditions, the fixing of the screw bolts in the region of each recess of the screw bolt caused by the locking element can be done by turning the screw bolt about its longitudinal axis and the screw bolt is then moved longitudinally, without being hindered by the locking or blocking that is possible in the area of each recess.
  • this is elastically flexible storage the locking element by a rotatable bearing achieved in connection with a spring that one Rotation of the locking element in one direction counteracts elastic.
  • This storage is very advantageous because the locking element is round on the outside executed and therefore in a (cylindrical) Bore can be stored, also as a blind hole can be trained.
  • the mentioned jaws of the device can in turn still with facilities e.g. in the form of a threaded hole be equipped to tie rods or similar here To be able to attack tensile elements. It is so possible, the clamping or separating device with advantage can also be used as a puller.
  • the separator essentially consists of two contractible jaws 1, 2 which are yoke-like are arranged and 3 holes at each end Have inclusion of bolts 4, 5.
  • the separator essentially consists of two contractible jaws 1, 2 which are yoke-like are arranged and 3 holes at each end Have inclusion of bolts 4, 5.
  • the Bracket 14 is in a cylindrical blind hole 15 rotatably mounted; on the outer circumference it is from the inner surface of the blind hole 15 and at both ends on the one hand from the reason 16 and on the other hand from one Circlip 17 guided and held, which in turn a Falling out of the bracket 14 prevented.
  • the holder 14 still has sides on all sides Projections 18 on the outer circumference, with which the Bracket 14 abuts at both ends.
  • bracket 14 Spring 19 acts against the direction of insertion 20 of the two bolts 4, 5, in such a way that, when de-energized, it is offset by approximately 90 ° relative to the operative position of the nose 13 shown in FIG. 1 (the tip of the nose approximately at 21 is arranged).
  • the device first step by step to the desired jaw spacing can be set.
  • the force and the actual separation process is then done by tightening the nuts 7.
  • the invention may also apply to such pairs of jaws can be used, which are articulated at one end connected and at the opposite end to one Bolts are provided.
  • the free ends of the bolts 4, 5 are conical, that is, it is rejuvenated. This is ensures that when inserting the bolts 4, 5 in the direction of arrow 20, the locking element 13 is displaced by rotating its holder 14.
  • the mounting of the bracket 14 in a hole has the Advantage of simple manufacture; in addition, the In contrast to FIG. 2, the holder 14 is also designed in this way be that the outer surface of the bracket 14 with the adjacent surface of the jaws 1, 2 is flush.
