Definitions

  • the invention relates to a device for clamping a workpiece on a tool, of the type comprising a flange actuated by a jack, which retracts and moves linearly in the clamping phase.
  • Such a clamping device is known from the document FR 2 863 190 patent application filed by the present inventor.
  • This device comprises a body having a lower portion of cylindrical shape and a top portion in the form of a yoke.
  • a flange is mounted movably between the two wings of the yoke and is actuated by the rod of a jack housed in the lower part.
  • the flange is struggling between a clamping position and a releasing position.
  • the movement of the clamping position towards the release position comprises a first phase of translation parallel to the axis of the jack followed by a phase of rotation to clear access to the tool to remove the piece and to place another one.
  • the movement from the release position to the clamping position follows the same path, in the opposite direction to the previous one.
  • the flange In the positions of the translational phase, the flange is guided by bearing elements formed by heels of the flange and bearing surfaces of the wings of the yoke. It is also guided by a pivot at the end of the stem.
  • the geometry of the triangle formed by the axis of the pivot, the support elements and the point of contact of the flange on the part determines the amplification of the forces applied to the part and which are transmitted in the form of a couple between the pivot and the support elements.
  • Such a device gives complete satisfaction, in particular in terms of speed of actuation and compactness, when the point of support on the part can be close to the device.
  • this support point is away from the clamping device, due to the constraints of the geometry of the part.
  • This is possible by an elongation of the flange, but such elongation increases the stresses on the pivot and the support elements or limits the clamping force if said constraints can not increase.
  • this elongation results in a larger footprint in the release position. Indeed, the flange has rotated about a quarter of a turn upwards and its length is added to that of the body in the direction of the cylinder.
  • a possible solution to increase the allowable forces is to move the support elements from the position of the pivot in the clamping position. This amounts to increasing the length of the body and the height of the flange, which increases the size of the device both in the clamping position and release position. This solution is therefore not optimal because of this overcrowding.
  • the object of the invention is to provide a compact tooling device which is compact, fast and powerful even if the clamping point has to be moved away.
  • the subject of the invention is a device for clamping a workpiece on a tool, comprising a jack and a flange, the jack being selectively actuated by a fluid under pressure and itself comprising a body intended for to be fixed to the tooling and a slide slidably mounted relative to the body, the flange being hinged about an axis of pivoting on the slide, the body having a front face beyond which the flange protrudes when in a clamping position to clamp the workpiece, the flange also having a release position that it at least partially reaches by a pivoting around the pivot axis, the device comprising guide members which comprise a guide member fixed relative to the body and a movable guide member connected to the flange cooperating with each other to drive the flange in a rotational movement around the pivot axis at least at the end of the stroke towards the releasing position and in a translational movement at least at the end of the stroke towards the clamping position, the device being characterized
  • the rotation during the release phase makes it possible to quickly release the flange to allow access to the workpiece on the tooling, to unload it and to load a new one in a direct movement along the front face.
  • This succession of movements is obtained with a simple command by a single cylinder.
  • the finger has the shape of a pin or a roller and is fixed on the flange at a distance from the pivot axis. If the groove was made on the flange, it would have the disadvantage of weakening the section of it.
  • the body can be made with a strong section that is not affected too much by the groove.
  • the groove extends along a path of which a first portion is parallel to the direction of translation of the flange and a second portion is oriented obliquely with respect to the first portion, the finger being in the first portion when the flange is in the clamping position or in the vicinity and in the second portion when the flange is pivoted.
  • the finger By acting on the finger during its movement in the groove, thus guides the movement of the flange, in particular to control the pivoting to the release position and the translation to the clamping position.
  • the relative position of the pivot axis and the roller is not changed, and the flange retains the same orientation, which determines a translational movement.
  • the roller is in the second portion of the groove, the relative position of the pivot axis and the finger is changed, and the flange pivots on the pivot axis.
  • the finger is located at a distance from the pivot axis, distant in the direction of translation of the rod from the clamping position to the release position. It is found that this arrangement is easier to achieve, leaving the space between the pivot axis and the cylinder rod without constraint to limit the length of the rod.
  • the slide comprises a piston and a rod joined together and the pivot axis is offset by a predetermined distance from the axis of the rod towards the front face.
  • the pivot axis is offset by a predetermined distance from the axis of the rod towards the front face.
  • the piston and the rod are assembled by screwing into one another.
  • the body comprises a plug for closing a cylinder chamber delimited by the piston and a bore of the body in which the piston slides.
  • the cylinder can be mounted by inserting the piston into the bore, assembling it with the rod, and then closing the bore with the plug to create the cylinder chamber.
  • the clamping device comprises upper support elements, the upper support elements comprising an upper stationary support element fixed with respect to the body, and an upper movable support element connected to the bracket. , the upper elements of fixed and movable support cooperating, at least at the end of the stroke of the flange to the clamping position, to offer each other a sliding contact parallel to the translational movement of the flange and to oppose the pivoting the flange to the release position. Direct transmission of forces is thus achieved between the flange and the body of the flange, which ensures good rigidity and good ability to cash the clamping forces.
  • the clamping device comprises lower support elements comprising a lower fixed support element, fixed relative to the body, and a lower movable support element connected to the rod, the lower elements of fixed and movable support cooperating, at least at the end of travel of the flange to the clamping position, to offer each other a sliding contact parallel to the translational movement of the flange.
  • the lower bearing elements for taking up forces transmitted by the flange during clamping via the rod.
  • the movable lower bearing element is at the pivot axis of the flange, so that the forces are transmitted without generating torque on the rod.
  • the clamping device comprises a detection duct opening on the upper fixed support element and intended to be connected in fluid communication with a leakage detection device fluid.
  • a detection duct opening on the upper fixed support element When the flange is in the clamping position, the upper fixed support member is in contact with the upper movable support element, which closes the outlet of the detection duct. There is thus a very compact element to detect the closing or opening of the flange.
  • the fluid used is typically air. It is also possible to provide a particular shape on the movable support element so that the detection takes place only in a very precise position range.
