Definitions

  • the present invention relates to a clamping device, in particular for use in 5-axis milling machines, with at least two clamping blocks and a spindle for adjusting at least one clamping block.
  • the movable clamping block driving spindle is located in the foot area in the housing of the clamping device in the vicinity of a machine table of the 5-axis milling machine. The clamping force applied by the spindle is transmitted to the workpiece via a carriage and the clamping jaw attached thereto.
  • the force acting on the movable clamping block tensile force of the spindle and the force exerted by a clamped workpiece on the movable clamping block pressure force can be considered in a first approximation as a pair of forces with parallel, opposite lines of action with a certain distance a. Since, due to the spindle arrangement according to the invention, a much smaller distance a is provided in comparison to the clamping devices of the prior art, the resulting torque is also substantially smaller. This prevents buckling of the tensioning device under load.
  • the device according to the invention a Niederzugelement for the workpiece, so that the movable clamping block moves due to its fixation on a machine table with its end facing the workpiece in the same direction and thus pulls down the workpiece.
  • an additional connection between the clamping device and spacer block as well as this itself can advantageously be dispensed with. This reduces the cost of the device.
  • At least one support plate for spacing a workpiece is provided by a machine table, wherein preferably each clamping block is associated with a support plate, which is preferably an independent of a clamping block integral component.
  • each clamping block is assigned its own support plate, the positioning of the workpiece is particularly accurate.
  • the support plate is independent of the respective clamping block component, advantageously, the manufacture and construction of the device can be simplified and yet its effect can be improved.
  • the support plate can be easily fixed on a machine table and fixed to the respective clamping block, so that no unwanted changes in position are possible.
  • spindle nuts of different lengths are connected to each other connectable, preferably against rotation and / or the spindle nuts have a marking as a positioning aid.
  • the first measure advantageously opens up a simple possibility of achieving even larger grips by combinations of several spindle nuts.
  • the appropriate spindle nut or the matching spindle nut combination can be selected without a variety of different spindle nuts would have to be kept with a fixed clamping width.
  • the rotation can be done in any known to the expert way, preferably at least by means of a tongue and groove connection.
  • connection is preferably made such that a spindle nut portion is connected to a coupling piece, in which engages the spindle screw or another spindle nut.
  • a coupling piece in which engages the spindle screw or another spindle nut.
  • the second measure advantageously facilitates the quick and secure positioning of the spindle nut in the movable clamping block for its fixation and support by spindle bolts.
  • a spindle screw is formed engaging only in a spindle nut and / or has a relationewearhan Servicee, preferably by means of a circumferential groove, is advantageously ensured that there is no unwanted overdetermination in the total spindle, as in the intervention the spindle screw in several interconnected spindle nuts. Just as too much screwing the spindle screw must be prevented, too low screwing into the spindle nut must be avoided so that not the entire clamping force is applied over one or two pitches of the spindle nut thread. This is done by means of a dealtewearhan Attache on the spindle nut, which preferably consists of a circular and visually or haptic well perceptible groove.
  • the fixed clamping block has a spindle screw receptacle with a support bearing on which the spindle screw, preferably supported by disk springs, is supported, a stable mounting and permanent functionality of the spindle is advantageously achieved.
  • the spindle screw holder is mounted as a separate fitting by means of bolts in the fixed clamping block and therefore easily replaceable, for example, if the conical support surface should be worn.
  • wear is advantageously prevented by the use of a plate spring between the support surface of the spindle screw receptacle and a conical bearing surface of the spindle screw. In this way, the forces can be handled safely.
  • the spindle screw receptacle is fastened by means of bolts to the fixed clamping block and / or the bolts are designed as coupled bolts is advantageous achieved a simple interchangeability at the same time secure mounting of the spindle screw receptacle. If the bolts are coupled, they need not be individually attached and tightened by hand, but can be tightened coupled simultaneously.
  • the coupling can be realized in any way known in the art, for example, by a gear / shaft / gear connection between the two bolts.
  • the movable clamping block has a region of reduced material thickness, preferably in the region near the base, its elasticity is used in a simple manner for movement onto the workpiece.
  • the part above the area of reduced material thickness does not force down on a circular path in the direction of the machine table and thus acts as Niederzugelement.
  • the movable clamping block has a display of elasticity and / or the fixed clamping block has a spindle screw cleaning device, preferably a force-loaded Spanabstreifdorn or a Spanabstreif Structure.
  • the elasticity indicator By the elasticity indicator, a user is easily made aware of the elasticity range of the movable clamping block, so that a leading to damage the device operating error is avoided.
  • a spindle screw cleaning device is advantageously prevented that fine chips can penetrate into the sensitive thread. This is preferably achieved by means of a spring-loaded mandrel.
  • a plate holder preferably a sucking plate holder, is arranged between the clamping blocks.
  • the clamping device has a clamping system with Kirzuganker.
  • the tie rod is designed as a chain or rope. This design provides a simple and inexpensive tie rod, which is supported on the movable clamping block and clamped to the fixed clamping block and can be changed as needed. An elaborate spindle can thus be avoided.
  • the clamping jaws are designed for clamping round workpieces. This can be done in any way known to those skilled in the art and advantageously increases the workpiece types that can be machined on a clamping device according to the invention.

  • the adjusting spindle mount consists of a milling in the base body into which the adjusting spindle is inserted from above. Since the adjusting spindle does not have to transmit any clamping forces, it can be dimensioned relatively small.
  • the two-part clamping blocks consist of a base plate and an attachment, which are preferably connected to one another in an articulated manner.
  • a Niederzugelement is provided with great advantage, which prevents bulging of a tensioned workpiece, the bipartite allows the replacement of various essays while maintaining a base plate.
  • essays that can span, for example, round workpieces can be easily exchanged for others without a second base plate would be required.
  • the clamping blocks are designed to be removable from the base body upwards. In this way, they can easily be exchanged for differently designed clamping blocks and do not have to be led out of the main body in a cumbersome manner in the longitudinal direction.
  • This embodiment is also made possible in that the adjusting spindle is not encompassed by the threaded sleeve but is only surrounded. The removal is made possible in that the clamping block guide rails do not overlap the corresponding guide sections of the clamping body.
