Definitions

  • the invention relates to a device with a small vertical space for clamping a workpiece on a tool, of the type comprising a jack and a flange actuated by the jack.
  • Such devices according to the preamble of claim 1 are for example known documents DE 4007590 A1 , US 3,724,837 A , US 3,565,415 A , EP 0 663 268 A1 , DE 195 31 889 A1 and FR2 743 320 A1 .
  • machining tools for the manufacture of parts by removal of material.
  • Such tools are designed to be quickly put in place on a machine tool such as a machining center. They comprise keys for receiving and positioning one or more workpieces. They further include clamping devices to hold the workpiece in place during the machining phase.
  • the document FR 2 743 320 A1 shows an example of a clamping device operated by a fluid such as a hydraulic fluid or air.
  • the device comprises a jack and a flange, the flange being actuated by the jack via transmission means.
  • the flange moves in an arcuate housing, so that the flange moves in a pivoting motion.
  • a clamping surface at the end of the flange is intended to come into contact with the workpiece to be clamped so as to clamp the workpiece.
  • the device is intended to be fixed on the tooling.
  • Such a device effectively maintains the parts, and is of limited size relative to the plane of attachment of the device, thanks to the orientation of the axis of the cylinder substantially parallel to the plane of attachment.
  • the movement of berthing of the piece is made in a curved path and mainly oblique with respect to the support plane of the part. This results in a possible sliding of the piece on its supports and a variable positioning from one room to another.
  • the aim of the invention is to provide a clamping device with reduced overall dimensions with respect to a fastening plane and ensuring tightness and reliable positioning in the direction of the fastening plane.
  • the invention relates to a device for clamping a workpiece on a tool, comprising a jack and a flange, the flange being actuated by the jack via transmission means, the jack being selectively actuated by a fluid under pressure and itself comprising a body fixed in operation to the tooling by a fixing face, and a slide slidably mounted relative to the body along a slide axis substantially parallel to the attachment face, the flange struggling under the action of the cylinder between a clamping position and a release position in which it is recessed relative to the clamping position.
  • the device is characterized in that it further comprises guide members provided for driving the flange in a movement comprising a rotation about a pivot axis at least at the end of its stroke towards its release position and following a translational movement in a clamping direction oblique or perpendicular to the axis of the slider and perpendicular to the pivot axis at least at the end of its stroke towards its clamping position.
  • the device according to the invention can be put in place with the slide axis parallel to an attachment plane, which makes it possible to obtain a clamping movement perpendicular to the plane of attachment. As the clamping movement is straight, no sliding movement on the supports is induced for the workpiece to be clamped. This provides a high reliability of the attachment, while having a limited space above the attachment plane, due to the orientation of the cylinder.
  • the guide members comprise first guiding means and second guiding means spaced apart from each other so as to define the path of the flange between the clamping position and the releasing position.
  • the guiding means make it possible to define both the position of the flange and the orientation thereof.
  • first and second guide means respectively comprise a first and a second finger cooperating respectively with a first and a second cam.
  • the cooperation of a finger and a cam makes it possible to define the trajectory of a point of the flange in a plane. By combining two sets of this type, the path of the flange is completely defined.
  • the first finger is mounted on the flange while the first cam is carried by the body.
  • the first cam comprises a first portion in which the first finger is located when the flange is in the clamping position, the first portion being parallel to the clamping direction, and a second portion which is oriented towards the jack.
  • the first portion corresponds to the rectilinear movement towards the clamping position.
  • the orientation of the second portion provides a tilting of the flange, so as to clear the space above the room and facilitate its introduction or removal.
  • the second finger is mounted on the body while the second cam is carried by the flange extending rectilinearly and in the clamping direction when the flange is in the clamping position.
  • This arrangement allows the rectilinear movement of the flange to the clamping position.
  • the transmission means comprise a transmission pin and a transmission cam cooperating with each other. These means make it possible to transform the rectilinear motion of the slider into a movement combining a phase of rotation and a phase of translation in another direction.
  • the slide has a flat foot, the transmission cam being carried by the foot of the slide, the flange having a flange groove in which the foot extends and slides, the transmission cam being traversed by a pin forming the transmission finger.
  • the flange groove guides the slider to ensure the permanent orientation of the transmission cam.
  • the movement of the slider conditions the movement of the pin which drives the flange. This ensures the transformation of the sliding movement provided by the cylinder.
  • the pin is not oriented in the cam so that pivoting of the flange about the axis of the pin is allowed.
  • the transmission cam comprises a first portion inclined with respect to the axis of the slide, and a second portion substantially perpendicular to the axis of the slide and in which the transmission finger is located when the flange is in position of looseness.
  • the transmission finger engages in the second portion in the movement towards the release position, the driving of the flange is carried out substantially in the direction of sliding, which facilitates the tilting of the flange and decreases the stroke of the jack for tilting.
  • the body comprises a yoke, the yoke having two wings parallel to each other, the flange struggling between the wings. This can lead to a solid and balanced guide of the flange.
  • the wings protect the flange, especially against intrusions of chips or dust.
  • the device comprises first support elements and second support elements, the first support elements comprising a first support element fixed relative to the body and a first movable support element connected to the flange, the first fixed and movable support members cooperating selectively, at least at the end of the stroke of the flange towards its clamping position, to mutually offer a sliding contact parallel to the tightening direction, the second bearing elements comprising a second support element fixed relative to the body and a second movable support element connected to the flange, these second fixed and movable support elements cooperating selectively, at least at the end of the stroke of the flange towards its position of clamping, to afford each other a sliding contact parallel to the clamping direction, the first and second support members being spaced apart from each other to allow a bridging of the flange on the part. e to tighten.
  • the clamping forces are transmitted between the body and the flange by direct contact between surfaces of each of these parts, which ensures good rigidity of the clamping, without biasing the guide means.
  • the first fixed support element is constituted by a bearing surface of the body between the wings of the yoke, the first movable support element being constituted by a first heel of the bridle.
  • the second movable support element is constituted by two second bearing heels carried by the flange and extending symmetrically on either side of a median plane of the flange and the slide, transverse to the pivot axis
  • the second fixed support element is constituted by two body bearing grooves formed in the wings facing each other, on the sides of which the second support heels 'support symmetrically with respect to said median plane. The second support element is thus placed between the wings of the yoke and are well protected against chips and dust.
  • the slide is made by a rod and a piston joined by assembly, the rod being connected to the transmission means. It is thus possible to impart a substantial dimension to the transmission means, without being limited to the diameter of the rod. Indeed, by a two-piece design, we can introduce the rod on one side of the bore that guides the rod and bring the piston on the other side. The assembly is carried out for example by screwing the piston on the rod.
