Definitions
- the invention relates to a clamping or Separating device, esp. For removing bearing shells, with two cheeks passing through at least one Bolt are braced against each other.
- a clamping device having the two jaws, one of the jaws means a locking element can be clamped in a Rack engages.
- it is a Clamping device for fixing several layers of cloth or Fabric that can then be cut to size at the same time.
- the distortion takes place by adjusting the Bolt considerable time to complete.
- the invention is therefore the object of devices develop the type mentioned above so that the device quickly to different thickness workpieces attached, separated from these, but also the Time required for tightening the nuts considerably can be reduced.
- the invention is based on a clamping and Separating device, in particular for removing Bearing cups, with a first and second jaw, the by at least one bolt against each other are braced, wherein the at least one bolt at a first end having a threaded portion on the first jaw by means of a nut adjustable is attached.
- the bolt with several, over its length distributed, successively arranged depressions provided, in which a stored on the second jaw Locking element can engage.
- a stored on the second jaw Locking element can engage.
- these depressions in the manner of rounded notches executed, while preferably in the form of a nose executed blocking element optionally in one of the notches can intervene.
- the recesses are carried out that they are only part of the scope of the Extend bolt. Will be under These conditions, the locking element elastic yielding, so can through the blocking element effected fixation of the bolts in the area of a each recess of the bolt by turning the Bolt raised about its longitudinal axis and the Bolt then be moved longitudinally, without thus through the possible at the area of each well Arret ist or blocking to be hampered.
- this elastically yielding storage of the blocking element by a rotatable mounting in Connection achieved with a spring the one Rotation of the blocking element in one direction of rotation elastically counteracts.
- This storage is very advantageous because the blocking element outside round executed and therefore in a (cylindrical) Bore can be stored, also called a blind hole can be trained.
- the mentioned jaws of the device can in turn still with devices e.g. in the form of a threaded hole be equipped here to tie rods or similar To let tension elements attack. It is so possible, the clamping or separating device with advantage to use as a peeling device.
- the separator consists essentially of two contractible jaws 1, 2, the yoke-like are arranged and each at both ends bores 3 for Receiving bolts 4, 5 have. Of the mutual distance of the two jaws 1, 2, to the mutually facing edges with a sharpness 6 can be changed, esp. but for the separation of Machine elements by mutual clamping of the Both jaws 1, 2 are reduced by the Nuts 7 of the bolts 4, 5 are tightened.
- FIG played Such an operation is schematic in FIG played.
- the two jaws 1, 2 engage in the Gap between a bearing shell a and a paragraph 8 a wave or axis 9 and thereby cause the desired separation of the bearing shell from its seat.
- the two jaws 1, 2 can then together with taking the bearing shell a using tie rods 10 in Direction of the arrow 11 are deducted.
- the bolts 4, 5 with several, exactly in the axial direction one behind the other arranged, rounded recesses 12 provided.
- the engaging in these wells to be engaged Blocking element is a rounded nose 13, which is attached an outer cylindrical holder 14 is located.
- the Holder 14 is in a cylindrical blind hole 15th 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 of a Circlip 17 guided and held, in turn, a Falling out of the bracket 14 prevented.
- the holder 14 still circulating Projections 18 on the outer periphery, with which the Holder 14 abuts both ends.
- the bolts 4, 5 against the direction of the To be able to move arrow 20 has the bracket 14 behind the nose 13 a recess 22 which is as follows acts. To pull out the bolts 4, 5 are this twisted about its longitudinal axis, that now the cylindrical, not through the depressions 12th interrupted outer surface of the bolt 4, 5 of Bracket 14 is opposite. This twist of the Bolt 4, 5 is possible because the holder 14th against the spring force is rotatable, so far, that the operating state according to FIG. 2 is reached. The recess 22 then allows an axial displacement of the Bolt 4, 5 readily to.
- the device first gradually to the desired jaw spacing be set. The force effect and the actual separation process then takes place by tightening of nuts 7.
- the invention is possibly. Also in such pairs of jaws can be used, which hinged together at one end connected and at the opposite end with a Bolt are provided.
- the free ends of the bolts 4, 5 are conical, so running rejuvenating. This is ensure that when inserting the bolts 4, 5 in the direction of arrow 20, the blocking element thirteenth is displaced by twisting its holder 14.
- the storage of the holder 14 in a bore has the Advantage of a simple production;
- the Holder 14 in contrast to FIG. 2 also executed be that the outer surface of the holder 14 with the adjacent surface of the jaws 1, 2 is flush.
