Definitions

  • the invention relates to a puller with an internal thread a traverse screwed-in pressure spindle, which has a thrust piece on one end for attachment one from a first one, starting from the traverse Claws placed on the component.
  • the puller has a traverse.
  • the traverse carries at least two claws that form hooks at the ends relocate a first component in which a second Component is inserted, which should be expressed.
  • the traverse usually has one in its center Inner thread.
  • the pressure spindle has one Rotary drive element, for example an opening for Pushing through a lever arm.
  • the pressure piece moves in the axial direction and pushes during its axial displacement the second component under constant application of force out of the first component.
  • the axial path that the Pressure piece covered corresponds to the distance to which the male thread of the spindle into the female thread the traverse is screwed in.
  • the invention is based on the object Generic puller the pressure piece essentially without shifting the thread to the attachment position relocate the exploitation of the maximum To optimize the displacement path determining the external thread.
  • the Rod swiveled in the direction of rotation, so it couples the rod with the threaded sleeve such that at one further rotation of the rod entrains the threaded sleeve is so that the pressure piece in the axial direction and in the direction of ejection according to the thread pitch shifted.
  • the rod can no longer in the axial direction relative to the threaded sleeve be relocated. Since the thread is preferred a fine thread can be a very large one Expressive force are applied. The strength can over the entire axial path used for expression must be maintained.
  • the length of the expression shift distance is essentially through the Length of the external thread of the sleeve is determined.
  • the configuration according to the invention is always the same Threaded section of the pressure spindle, which when pressing out in the internal thread because the axial distance of the Threaded section of the pressure spindle to the pressure piece is quickly adjustable.
  • the thread length of the threaded sleeve is preferably only slightly larger than that Expression path.
  • the axial length corresponds of the internal thread the axial length of the external thread. This ensures that in the final phase Pressurizing the largest number of threads are engaged to each other. It is also an advantage if the threaded sleeve at one of its ends Screwdriver attack protile trained.
  • the Screwing tool attack profile which is preferably from a six-sided design, preferably sits on the crosshead side opposite the claws.
  • the rod can preferably be one known rack act, which flattened on one side and rounded off on the other side. It is known such a rack in one with an external thread insert the provided sleeve, the sleeve in interspersed with at least one pen which is engaged by turning the rack is brought into a tooth gap. Another turning the rod takes the threaded sleeve with it.
  • Such Spindle arrangement is used in the prior art for clamping used by clamps or vices.
  • the rotary drive member is attached to one end of the spindle and is fixed there with a grub screw that is supported on the flat side of the rod. Is preferred but that the rotary actuator is fixed to the spindle is connected to optimal torque transmission to ensure.
  • the diameter of the pressure piece and the rotary drive member is preferably larger than the inside diameter of the threaded opening.
  • the puller has a crossbar 1, which consists of a cast metal part can exist.
  • the traverse 1 has a central opening with an internal thread 11 is provided.
  • the crossbar 1 boom that Form rails 14 on which by means of clamping pieces 15 claws 2 slidably arranged in said transverse direction are.
  • the claws 2 form hooks 16 at the end from, for reaching under a first component, from which a second component can be pushed out.
  • the clamping piece 15 is by means of clamping screws 19 on the Rail 14 brought into a clamping position.
  • the external thread has approximately the same axial length as that Internal thread 11.
  • the threaded sleeve has 4 at the end a hexagonal profile 5.
  • the threaded sleeve 4 is preferably screwed into the internal thread 11 such that the Hexagon profile 5 on the opposite of the claws 2 Side of the traverse 1 sits.
  • the central opening of the threaded sleeve 4 has essentially a round cross section.
  • the opening 21 is from three pins interspersed 10 secant, so that partial areas which is essentially a round cross section projecting pins 10 protrude into the threaded sleeve.
  • the opening 21 is axially formed by a rod 3 enforced.
  • the rod 3 is on one side in the axial direction provided with a flat 8.
  • the Rod 3 an outer contour formed by a curve 9.
  • teeth 7 educated are by essentially semicircular tooth gaps formed.
  • the toothing corresponds the diameter of the pins 10.
  • a pressure piece 12 At its end facing the claws 2 sits on the Spindle 3 is a pressure piece 12 with an end ball 17.
  • the diameter of the pressure piece 12 is larger than that Opening diameter 21. It can also be larger than the diameter of the internal thread.
  • Rotary drive member 13 which with a grub screw 18, which is supported in particular on the flattened portion 8, is attached to the spindle.
  • the rotary actuator 13 can have a transverse bore 22.
  • This cross hole 22 can form a hexagonal profile in one Section of the rotary drive member 13 is arranged his.
  • the length of the toothed section of the spindle 3 is considerably larger and in particular twice as much long, like the threaded sleeve 4.
  • the puller works as follows: First, the spindle is shown in Fig. 1 Positioned in which the threaded sleeve to on a few threads almost completely from the Internal thread 11 is unscrewed. In this position the rod 3 becomes one shown in FIG Brought rotary position, in which the flat 8 in Opposite sits to the pins 10. In this position can the rod 3 in the axial direction freely through the Opening 21 of the threaded sleeve 4 are shifted into a Position in which the ball 17 is on or immediately lies in front of the second component. This position is called Position designated. Then the rotary actuator 13 in particular rotated clockwise.
  • the rod 3 first rotates one Quarter turn inside the opening 21 until the teeth 7 mesh with the pins 10 (see FIG. 3). Then a stop edge 20 acts on the rod 3 the pin 10 so that a wide rotation of the rod 3 rotates the threaded sleeve so that the external thread 6 rotates in the internal thread 11.
  • This has an axial displacement of the pressure piece 12, which is first up to a contact position to the second component can bring.
  • Another turning action of the rotary drive element 13 causes the second to be expressed Component from the first component, the pressure piece 12 with constant application of force to the second Component moved a certain distance in the axial direction becomes. Rotates during this shift the threaded sleeve 4 into the internal thread 11, until the position shown in Fig. 6 is reached or before the squeezing process has ended.
