Definitions

  • the invention relates to an electrically actuated workpiece clamping device according to the preamble of claim 1.
  • Such a tensioning device is, for example, according to DE 36 38 526 C1 known.
  • the problem is that Force input in the case of electric drives at the expense of the overall width such jigs goes because there is a higher one Performance of the electric drive in the diameter of the Electric motor precipitates, which is then necessarily larger than the width of the clamping head.
  • the width is generally as narrow as possible strived for, but with the required high force input is not to be observed.
  • the innovation is based on the task of such a clamping device to train with regard to their drive and improve that despite high performance only requires a comparatively narrow overall width.
  • the distance between the side walls of the two engines Housing to each other is the same or substantially the same Width of the clamping head saddled on the housing, what nothing other than that of the respective clamping head
  • the specified width for the motor housing is fully utilized becomes.
  • the devices for converting the rotary movement into a translatory Movements are made up of the following elements:
  • Another advantageous training is that lower end of the hollow shaft at least the bottom of the housing engages flush with this and with one External drive connection element is provided. This leaves the Clamping device can also be operated in the event of a power failure or engine damage.
  • the electrically operated clamping device consists of a arranged on a clamping head 1 electric drive 2 for actuation a threaded spindle 3, which is arranged in the clamping head 1 Actuating mechanism SM for the tension arm 4 in operative connection stands.
  • the clamping head 1 with its adjusting mechanism SM and its function does not require any special explanation, since well known, quite apart from the fact that such Clamping head or such a clamping device without further ado with a pneumatic or hydraulic actuating cylinder operate, only the threaded spindle 3 through the Push rod of the respective actuating cylinder would be replaced.
  • this distance A is dimensioned such that that this is preferably the same or substantially the same Width B of the clamping head 1 saddled on the housing 5 is.
  • the devices 7 for converting the rotary movement into a Translational movement consists in particular of an between the motors 6 rotatably mounted with a gear 12 provided hollow shaft 13, in which the threaded spindle 3 at Immersed axial adjustment.
  • On the output shafts 14 of the two Motors 6 are with the gear 12 of the hollow shaft 13 in Engaged drive pinion 15 arranged, the rotation thereof so that the hollow shaft 13 is translated accordingly whose rotation in turn preferably as a recirculating ball nut trained transmission element 16 as a translational adjustment movement the threaded spindle 3 is transmitted.
  • This transmission element 16 or this ball nut is 1, fixed in a pot-like extension 17 housed at the upper end of the hollow shaft 13, which Extension 17 at the same time and as indicated for the axial and Radial bearing of the hollow shaft 13 at its upper end region is exploited.
  • this embodiment according to FIG. 1 stands So the non-rotating threaded spindle 3 in direct connection with the first link of the actuating mechanism.
  • the gear 12 and the drive pinion meshing with it 15 of the two motors 6 are advantageous and easily accessible at the lower end of the hollow shaft 13, as shown in Fig. 1, the lower, the lower end portion of the hollow shaft 13, the gear 12 and the Drive pinion 15 receiving part of the housing 5 as this releasable housing part 5 'is assigned.
  • this element is simply a polygonal pocket hole into which a corresponding one, for example Allen key is inserted to avoid failure the motorized drive is adjusted manually to be able to make.
  • Control electronics housing 22 On the rear narrow side 21 of the housing 5 is a Control electronics housing 22 attached, which in the clamping head 1 end position sensors 23 in Connection is established.
  • the housing 5 can heat in the area of the motors 6 with wall openings 24 be provided, through which a direct heat radiation is made possible. That being said, by that thin-walled housings, particularly in the area of the motor arrangement 5 per se at least for sufficient heat dissipation taken care of.
