Definitions

  • the present invention relates to a clamping device according to the preamble of claim 1 for fixing workpieces and relates in particular to a clamping device with a pivotally mounted on a housing clamping arm, which can be brought by means of a actuated by a drive actuator in clamping position to be fixed workpiece and again can be swung back from this position.
  • Clamping devices of the type mentioned are known in various embodiments.
  • Such an embodiment according to DE 10 2005 005 340 A1 comprises a head piece with an adjusting mechanism for a pivotable on the head piece in clamping position and open position clamping arm and a head piece bearing housing with an interior for receiving a hand with the adjusting mechanism and on the other hand with a in the housing arranged drive connected, linearly adjustable control rod.
  • a similar construction is also based on a clamping device according to US Pat. No.
  • the housing also formed from one piece, which is drilled cylindrically except for a floor education left standing.
  • the adjusting mechanism containing head piece, which is also arranged on the associated with the adjusting mechanism clamping arm, in this case has an appropriate in the cylindrical bore of the housing extension, which has about half the length of the housing and which serves to seal the cylinder space and to limit to guide the control rod.
  • the starting material for the housing is an extruded profile which corresponds to the outer shape of the housing of the clamping device and is intricately machined on the inside, ie an extruded profile made of solid material.
  • the invention has the object To simplify the construction and production costs for such a clamping device.
  • the housing is designed in the form of a hollow extruded profile, wherein the interior has a constant inner cross-section over its entire length.
  • Figure 1 shows a section through the clamping device according to the invention with the clamping arm in clamping position
  • Figure 2 shows in section the device according to Figure 1 with the clamping arm in the open position
  • FIG. 3 shows a section through the tensioning device with an alternative drive
  • Figure 4 shows in perspective an embodiment of an extruded hollow profile
  • FIG. 5 shows the extruded hollow profile according to FIG. 4 with an attached head piece.
  • the clamping device to be described below consists in a known manner of a head piece 1 with a built-in adjusting mechanism 3 for a pivotally mounted on the head piece 1 clamping arm 6.
  • This clamping arm 6 sits in the embodiment on both sides of the headpiece outstanding square pin 22 and is in clamping and opening position ( see FIGS. 1 and 2) by corresponding rotation of the square pins 22.
  • the head piece 1 with its adjusting mechanism 3 and the clamping arm 6 is arranged on a housing 7.
  • the interior 9 of the housing 7 serves to receive a linearly adjustable adjusting rod 13 connected on the one hand with the adjusting mechanism 3 and on the other hand with a drive 12 arranged in the housing 7.
  • the housing 7 is designed in the form of an extruded hollow profile 8, the interior 9 of which has a constant internal cross-section Q over its entire length L.
  • This housing 7 in the form of an extruded hollow section 8 forms a kind of a basic component for the construction of the entire clamping device.
  • the extruded hollow profile 8 preferably has a rectangular outer cross section, although the illustrated, concrete embodiment is not mandatory, ie, the extruded hollow profile 8 could also have, for example, a quadratic profile. have a cylindrical or circular cross-section.
  • the inner cross-section Q can optionally be circular or elliptical (see FIG. 4), but also rectangular.
  • a circular inner cross section in Figure 4 is indicated by dashed lines.
  • the extruded hollow profile 8 according to the invention can also be provided on its outer surface, ie, in particular on its flank surfaces F with connecting elements, preferably in the form of grooves 21, which can be formed during extrusion with. As far as this is a transverse groove 26, as shown in Figures 1 to 5, this transverse groove 26 must be subsequently cut on the extruded hollow section 8.
  • the relative to the total length L of the extruded hollow section 8 relatively short or small head piece 1, which contains only the adjusting mechanism 3, as shown in Figures 1 to 3 and 5, in the form of a cap formed with its at least partially open side is arranged on the head end open side of the extruded profile 8 and firmly connected in a suitable manner with the extruded hollow section 8.
  • the at least partially open side of the cap ensures that a drag member 5 belonging to the actuating mechanism 3 can emerge from the short head piece 1 and engage in the extruded profile 8.
  • the body of the extruded hollow section 8 or the actual housing 7 of the tensioning device thus remains advantageously unaffected by the placement of the actuating mechanism 3 composed of the lever arm 4, an actuating shaft, not shown, with its protruding square pins 22 and the drag member 5.
  • the head piece 1 is formed from two cup-shaped and with suitable means against each other firmly joined together head piece parts 2, as illustrated in Figure 5.
  • the tensioning arm 6 is required for such tensioning devices, which is the case in the rule, is for the attachment of a suitable sensor 19, the Extruded hollow section 8 head side provided with a simple cut ororganizfräsenden lateral opening 18 for receiving such a sensor 19, wherein such a slot-like opening 18 is preferably disposed in the region of one of the grooves 21.
  • the control rod 13 is provided with a position transmitter 20, which therefore participates in the up and down movement. From the usually provided installation of such a sensor 19 so the head piece 1 advantageously remains completely untouched, ie, such installation is limited solely to the extruded hollow section. 8
  • the housing 7 is formed by an arbitrarily long, cut to size extruded hollow section 8 and this is completed at one end of the head piece 1, and the head end remote end of the extruded hollow section 8 is to be provided with a suitable closure, d. H. , This can be done with a correspondingly adapted cover member 17, as shown in Figures 1 and 2.
  • the extruded hollow profile 8 essentially and preferably corresponds to at least twice the length of the required travel S, which is correspondingly implemented by the actuating mechanism 3 for the pivotal movement of the clamping arm 6 from the open position (FIG.
  • Figure 2 in the clamping position ( Figure 1) and vice versa is necessary, there is a clear outline of the interior 9 in the housing 7 and in the extruded hollow section 8, which, since the interior 9 is continuously free of any installations or cross-sectional constrictions, the possibility of Freedom of choice for the drive 12 of the control rod 13 is opened, that is, the usually arranged in the lower part or in the head portion facing away from the head portion 9 of the extruded hollow section 8 drive 12 may advantageously be formed either as a pneumatic, hydraulic or electric drive.
  • the illustrated actuating mechanism 3 is to be understood as an example only, since other actuating mechanisms (eg. so-called curve drive - see DE 10 2004 007 465 Al) can be used.
  • the intermediate wall 15 Since the inserted into the Stranpresshohlprofil 8 intermediate wall 15 must be fixed and sealed, the intermediate wall 15 is provided with a ring seal 23 and is fixed on one or both sides by means of only indicated holding elements 24.
  • a rotary shaft of the electric drive which is preferably embodied as a reversing motor 16, is operatively connected to the actuating rod 13 with the intermediary of a converter 25 for rotational movement, which is only indicated by dashed lines in FIG.
  • reversing motors 16 which can rotate in two directions, and converter 25 are well known and require no particular explanation in this respect.
  • the extruded hollow section 8 can be closed below by a cover member 17, but it is also an embodiment to the effect that the electric drive or the reversing motor 16 with its outer housing, not shown itself forms a headpiece remote closure of the extruded hollow section 8.
