Definitions

  • the invention relates to a ring pliers according to the preamble of claim 1.
  • Ring tongs of the type mentioned here are known. They are used to mount and remove circlips.
  • the rings discussed here are circlips that can be used to axially secure a shaft in a groove which is introduced into the peripheral surface of the shaft. They also serve to insert rings in grooves which are made in an inner surface of a bore.
  • the rings discussed here are also referred to as Seeger rings, which are formed as open rings with engagement openings in the end regions. The end portions of such a ring must be widened if they are to be inserted into the groove of a shaft. Accordingly, the ends must be compressed so that the outer diameter of the ring is reduced when it is to be inserted into a groove introduced in a bore surface.
  • the object of the invention is therefore to provide a ring pliers of the type mentioned here, can be used with the retaining rings, regardless of whether they are to be used in grooves on the outer surface of a shaft or in grooves in the inner surface of a bore.
  • the conversion of the ring pliers to the two modes of operation should be done in a simple manner to avoid complex designs and high production costs.
  • a ring pliers which has the features mentioned in claim 1 and two pivotally connected by a hinge handles and two handles associated with the functional ends, which are arranged on the opposite side of the handles of the joint. It is further provided that at least one function end relative to the associated handle can be arranged in at least two angular positions and rotatable about an axis of rotation.
  • the ring pliers is characterized in that the functional end has a supporting part adjoining the associated handle and a grip part adjoining thereto and extending therefrom, which is arranged on the side of the carrying part facing away from the associated handle.
  • the support member is rotatable relative to the associated handle about an axis of rotation which encloses an angle with the central axis of the handle portion of the functional end. If the function end for switching the operation of the ring pliers around the axis of rotation of the support member rotated in a first angular position, the central axis of the handle portion is in a first functional position of the ring pliers on one side of the axis of rotation of the support member and in the other second functional position on the other side of the Rotary axis of the supporting part.
  • the operation of the ring tongs quasi be switched: In the first angular position, the function ends are moved towards each other when closing the handles, while they move away in the second functional position when closing the handles of each other.
  • FIG. 1 shows a Ringzange 1, which is also referred to as circlip pliers or Seeger ring pliers. It has two handles 3 and 5, which are connected via a hinge 7 pivotally connected to each other. The pivoting movement takes place through a pivot axis extending through the joint 7.
  • the handles 3 and 5 functional ends are provided, wherein a first functional end 9 of the first handle 3 and a second functional end 11 is associated with the second handle 5.
  • the functional ends 9, 11 are provided with tips 13 and 15 which are formed, preferably cylindrical, in such a way that they can be introduced into holes provided in the end regions of the retaining rings.
  • the first functional end 9 is fixedly connected to the first handle 3, while the second functional end 11 relative to the associated second handle 5 can be arranged in at least two angular positions.
  • the second functional end 11 can be removed from the second handle 5, rotated and inserted in another angle position again in this.
  • the second functional end 11 it is preferably also possible for the second functional end 11 to be rotatable relative to the second handle 5, wherein the second functional end 11 can engage with a pin in the joint region of the handle 5 or a projection of the handle 5 is inserted into the second functional end 11.
  • the second functional end 11 is rotatable relative to the second handle 5.
  • FIG. 1 it is arranged in a first angular position, in which it points in the closed position of the two handles 3 and 5 obliquely downwards. It may be that the ring tongs 1 opposite to in FIG. 1 shown position can still be closed.
  • the second functional end 11 does not need to be designed 360 ° relative to the handle 5 to be rotatable; it is enough if it is designed so that it can be swiveled through 180 °.
  • the second functional end 11 has an adjacent to the second handle 5 support member 17, also facing away from the hinge 7 adjacent to the support member 17 handle member 19 with the top 15.
  • the support member 17 is rotatable about an axis of rotation 21 or pivotally relative to the second Handle part 5 is formed.
  • the support member 17 may be inserted into the handle part 5 so that it is not rotatable in the inserted position.
  • the support member 17 is pulled out of the handle portion 5, rotated about the rotation axis 21, preferably 180 °, and plugged again.
  • the support member 17 is formed so that it does not have to be taken out of the handle part 5 for rotation or pivoting about the rotation axis 21.
  • FIG. 1 clearly shows that the handle portion 19 is angled relative to the axis of rotation 21, ie relative to the support member 17, so that its central axis 23 with the axis of rotation 21 forms an angle ⁇ .
  • FIG. 2 is the ring tongs according to FIG. 1 shown in a second functional position, namely open.
  • the same parts are provided with the same reference numerals, so far as the description to FIG. 1 is referenced.
  • FIGS. 1 and 2 A comparison of FIGS. 1 and 2 shows that the handles 3 and 5 have been moved away from each other according to the double arrow 25. It is clearly recognizable that the in FIG. 1 V-shaped unfolding function ends 9 and 11 are now practically superimposed in the open position of the handles 3 and 5, so are closed. The tips 15 and 17 are now at a minimum distance from each other and can be inserted into the openings provided at the end of a Seeger ring, whereby it is readily possible is to adjust the distance of the tips 13 and 15 to the distance of the openings.
  • FIGS. 1 and 2 it turns out that the according to FIG. 2 opened pliers can be engaged with the openings at the ends of a Seeger ring.
  • the pliers is closed, the two handles 3 and 5 are moved towards each other, so that the ring pliers 1, the functional position according to FIG. 1 accepts.
  • the tips 13 and 15 are then at a distance to each other, so that a detected Seeger ring is widened. It can now be slid over a shaft to insert the Seeger ring in a groove provided in the outer surface of the shaft.
  • FIG. 3 shows the ring tongs 1 turn in the closed state.
  • the handles 3 and 5 are -as in FIG. 1 - thus approximated to each other.
  • the same parts are provided with the same reference numerals, so that reference can be made to the description of the preceding figures.
  • a second functional part 11 which is attached at least by 180 ° to the second handle 5, is preferred, as is described with reference to FIGS FIGS. 1 and 2 was explained. It has a support member 17 which is rotatable about an axis of rotation 21 relative to the second handle 5, and a handle portion 19, the central axis 23 with the axis of rotation 21 connects an angle.
  • the handle member 19 is thus opposite to the support member 17 as well as in the FIGS. 1 and 2 shown, angled.
  • FIG. 4 shows the ring tongs 1 in a second functional position:
  • the handles 3 and 5 are shown in their open position, ie at a distance from each other, which is indicated by the double arrow 25.
  • the second functional end 11 when it is in its second angular position relative to the second handle 5, away from the first functional end 9 when the two handles 3 and 5 are opened, so also from each other be moved away. Accordingly, the tips 13 and 15 are arranged at open handles 3 and 5 at a distance from each other.
  • the two tips 13 and 15 of the function ends 9 and 11 are approximately in one plane. This is preferably arranged so that the pivot axis of the two handles 3 and 5 extending through the joint 7 is substantially perpendicular to this plane. To achieve this, the fixed first functional end 9 of the first handle 3 is preferably bent in its end region 27.
  • FIGS. 1 to 4 the ring tongs 1 is shown in a perspective side view, in which one looks at a hinge plate 29 of the second handle 5. This essentially hides the hinge plate 31 of the first handle 3.
  • FIG. 5 shows the ring pliers 1 in the closed position, wherein the second functional end 11 relative to the associated second handle 5 is in its second angular position, as in FIG. 3 is shown.
  • the handles 3 and 5 of the ring tongs 1 are in their approximate position, with the tips 13 and 15 of the function ends 9 and 11 are in their approximate position, because, as I said, the second functional end 11 in accordance with its second angular position FIG. 3 located.
  • FIG. 6 again shows the ring pliers 1 in a perspective view obliquely from the front, as shown in the illustration FIG. 5 , Identical parts are provided with the same reference numerals, so that reference is made to the description of the preceding figures.
  • FIG. 6 the ring tongs 1 is shown closed, that is, the handles 3 and 5 are in their approximate position.
  • FIG. 7 finally shows the ring tongs 1 in the same perspective view as in the Figures 5 and 6 , ie obliquely from the front, looking obliquely on the hinge plate 31 of the first handle 3.
  • Identical parts are again provided with the same reference numerals, so reference is made to the description of the preceding figures.
  • FIG. 6 and 7 The only difference between FIG. 6 and 7 is that the second functional end 11 was further rotated according to the arrow 33 about the rotation axis 21. It becomes quite clear that in a further rotation of the second functional part 11 about the rotation axis 21, this assumes the first functional position, as in the FIGS. 1 and 2 was presented.
  • the tips 13 and 15 are at a distance from each other in an imaginary plane, although the position of the handles 3 and 5 in the Figures 5 . 6 and 7 remained unchanged.
  • the plane is preferably oriented so that the pivot axis of the joint 7 is perpendicular to it.
  • this is a ring pliers 1 realized, which is suitable both for mounting and dismounting of Seeger rings, which are used in the peripheral surface of a shaft, as well as for the assembly and disassembly of Seeger rings, in a groove of the inner surface a hole to be used.
  • the second functional part 11 in the associated second handle part 5 in two angular positions can be inserted, or whether this relative to the second handle part 5, as based on FIGS. 1 to 7 explained, is pivotally or rotatably designed. It is crucial that at least one of the functional parts, here the second functional part 11 in two angular positions relative to the associated second handle 5 can be arranged so that on the one hand at a closing movement of the handles 3 and 5, the tips 13 and 15 of the handles 3 and 5 are moved away from each other as this is based on the Figures 2 and 1 has been explained or moved towards each other as shown by the FIGS. 4 and 3 becomes apparent.
  • the rotatably mounted on the second handle 5 second functional end 11 in the two apparent from the figures functional positions can be locked so that it can not rotate arbitrarily.
  • ring tongs is easily switchable to use them on the one hand to use rings in the outside of a shaft and on the other to introduce rings in the inner surface of a bore.
  • corresponding grooves are provided on the outside of the shaft and on the inside of the bore, which receive the rings safely.
  • the ring tongs are characterized by a very simple structure. It only requires the arrangement of at least one of the function ends relative to the associated handle in at least two angular positions. In the embodiment shown here only one function end is positionally variable.
  • the functional end 11 can be arranged relative to the associated handle 5 in two angular positions, either in which it can be inserted in these two angular positions in the handle or can be arranged pivotably or rotatably thereto.
  • the ring pliers is characterized in that only the change in the angular position of the at least one functional end is sufficient to change the operation of the ring pliers, it does not require switching device that engages in the pivotal movement of the handles or the coupling of the handles with the function ends.
  • the ring tongs is therefore very simple, inexpensive to produce and very reliable.
