Definitions

  • the present invention relates to a clamping unit for clamping a shaft or rod.
  • Object of the present invention is to provide a clamping unit, which does not have the above-mentioned disadvantages of the previously known clamping units, ie a gentle, large-scale and centric Clamping force exerted on the festzuklemmende shaft or rod, self-centering acts on the latter, and overload only allows slipping of the clamped object but no dangerous opening of the clamping unit under certain circumstances.
  • the first exemplary embodiment of a clamping unit according to the invention shown in these figures, has a cylindrically shaped clamping part 3 provided with a receiving bore 2 intended to receive a shaft 1, which is positively and non-positively enclosed in a clamping element 3 surrounding it cylindrically shaped housing 4 extends into it.
  • the housing interior extending upper end portion of the clamping member 3 is tapered upwards and provided parallel to the longitudinal axis 5 of the receiving bore 1 with a extending into the latter slot 6, which a relative movement between the two sides of this slot 6 adjacent parts 3a and 3b allowed when exercising a perpendicular to the slot 6 and laterally on these two parts 3a and 3b pressing force.
  • the receiving bore 2 is dimensioned such that there is a sliding fit between the outer surface of the shaft 1 and the bore 2.
  • the separated over the slot 6 tapered end portion 3a, 3b of the clamping member 3 is positively surrounded by a support ring 7 which is provided on its inwardly directed side with a spherical recess 8, in which a the shape of a spherical cap exhibiting pivotable clamping element 9 engages.
  • the support ring 7 is also on its cylindrical outer side 10 positively against the inside of the housing 4 and / or on the tapered end portion 3a, 3b centered resting.
  • the clamping element 9 is firmly connected on the one hand via a connecting element 11 with a pivotally mounted within the housing 4, and at the free end by means of a spring element 12 resiliently applied to the underside 13 of the piston 14 pivot member 15, and on the other hand perpendicular to the slot 6 via a Ball 16 indirectly on the outside of the tapered end portion 3a, 3b, such that upon pivoting of the spherical cap 9 perpendicular to the slot 6, a pressure on the outside of the adjacent part 3a of the tapered end portion 3a, 3b of the clamping part 3 is exercised.
  • the spherical support member 16 can be adjusted perpendicular to the slot 6 by means of a threaded pin 17 exactly fitting on the contact surface of the clamping element 9.
  • a bore 18 is provided in the part 3b, through which a screwdriver can be guided into engagement with the threaded pin 17 therethrough.
  • the clamping part 3 is in its below the longitudinal axis 5 of the receiving bore 2 located to increase the bending elasticity of the two separate End Schememaschine 3 a, 3 b of the clamping member 3 in a relative movement of these two End Schememaschine 3 a, 3 b to each other for clamping a shaft 1 with a against the Receiving bore 2 to and one of this centrally away downwardly extending weakening notch 19 and 20 provided.
  • the housing 4 is provided on its upper side with a fluid connection 21 for supplying and discharging a gaseous or liquid pressure medium for actuating the clamping unit.
  • FIGS. 3 to 6 show a second exemplary embodiment of a clamping unit according to the invention, in which analog parts are provided with the same reference numbers for the first embodiment shown in FIGS. 1 and 2, so that a repeated description of analog parts is not necessary.
  • the tapered end portion 3a, 3b of the clamping member 3 is penetrated by a transverse to the slot 6 extending tie rod 22, which is provided at its one end to its anchoring in one end portion 3b with a nut 23 and at its other end with a pressing arrangement is.
  • this pressing arrangement on a pivotally mounted in the tie rod 22 eccentric 24, which is rigidly connected to a against the piston bottom 13 extending pivot lever 25, which at its free end via a spring element 12 in the clamped state of the clamping unit to the bottom 13 of the actuating piston 14th is created.
  • FIG. 3 shows the clamping unit in the clamped state
  • FIG. 5 shows the clamping unit released into the shaft 1, i. the clamping unit clamps by means of spring force and is released using a gaseous or liquid pressure medium.
