Definitions

  • the invention relates to a device for lateral clamping of workpieces on a machine tool, in particular for clamping deformed or very high workpieces.
  • the invention aims to remedy these drawbacks and to this end relates to a device which by its design and its ease of adaptation, allows the reliable and effective clamping of all parts to be machined whatever their shapes and their heights.
  • the invention therefore relates to a device for lateral clamping of workpieces on a machine tool characterized in that it consists of at least one slide provided with an anchoring element, movable in translation in the slide, under the thrust of a pressure member, the active part of the anchoring element, projecting relative to the front face of the slide, comprising at least one rigid abutment zone and at least one flexible abutment zone.
  • the anchoring element is made of spring steel and is associated with a control screw immobilized axially but movable in rotation, the active part of this element being formed by three fingers curved downwards, the middle finger being set back from the two adjacent side fingers and being reinforced to form a rigid abutment area, while the two side fingers are thin in order to be slightly flexible, and are set back from the underside of the anchoring element to be able to bend slightly downwards during bending.
  • the essential object of the invention lies in the particular design of a lateral clamping device making it possible to fix on the table of a machine tool parts to be machined, whatever the shape of their contour and especially whatever their height.
  • This device essentially consists of a stirrup-shaped profile hereinafter called a slide.
  • This slide 1 whose section is more particularly visible in Figure 2 comprises a male part 1 1 and a female part 1 2 of complementary shape.
  • the male part is in the form of a parallelepiped head provided on its two lateral edges with two shoulders 2 projecting from the lateral face 3. These two shoulders are connected with the lateral face 3 by two slightly inclined edges 4.
  • As for the female part it internally comprises a housing 5 having a section complementary to the male part 11.
  • Each slide is in the form of a section of profile and can be assembled with a continuous slide by simple fitting of the male part d 'a slide in the female part of the other.
  • Each slide is also provided with an anchoring element 6 mounted movable in alternative translation in a housing 7 made in the male part 1 1 of the slide.
  • This housing 7 extends only over a part of the length of the slide, the rear part of the latter being closed by a wall 8 pierced with a circular orifice 9 allowing the passage of a control screw 10.
  • the head 11 of this screw protrudes outside relative to the front face 12 of the slide while its threaded front part cooperates with a threaded orifice 13 formed in the anchoring element 6.
  • This screw also has an annular shoulder 14 coming to bear, at the end of the rear stroke, against the rear wall 8 of the slide.
  • the anchoring element 6, (FIGS. 4 and 5), is in the form of a parallelepipedal block whose front part called the active or operational part is produced in the form of three fingers 6 1 , 6 2 and 6 3 these fingers being curved downwards and being obtained by simple saws 15 and 16.
  • the central finger 6 2 has a stiffening rib 6 4 intended to stiffen it in order to constitute a stop which will come to bear, during clamping, on the part P, (Fig. 1.).
  • the two lateral fingers 6 1 and 6 3 are of thin thickness so as to be slightly flexible, the anchoring element being for this purpose made of spring steel (steel 45 S 8).
  • the fingers 6 1 -6 3 are slightly projecting from the front face 6 5 of the middle finger 6 2 and also set back from the reference plane 6 6 that constitutes the underside of the anchoring element 6.
  • This design is intended for the lateral fingers 6 1 and 6 3 to come into first in contact with the part to be clamped and they can deform downwards until they come flush with the level of the lower face 6 6 of the anchoring element 6.
  • the two fingers 6 1 and 6 3 , and more particularly the front face are substantially on the same plane of the front face 6 5 of the middle finger 6 2 so that the three fingers are in symmetrical support on the workpiece.
  • the flexibility of the metal in particular, the flexibility of the lateral fingers 61, 63 increases by simply bending the bracing pressure of the three anchoring fingers on the part.
  • the pushing agent of the anchoring element 6 is, as indicated above, the control screw 10.
  • the latter is immobilized in axial translation by a lug 17 situated in a plane orthogonal to the screw 10 and coming to be housed in part in an annular groove 18 which is provided with the screw.
  • the screw can only move in rotation which is transformed by a translational movement of the anchoring element 6 in the direction of the part P until the two lateral fingers 6 1 , 6 3 of this element anchors come into contact with this part.
  • the two flexible fingers 6 1 , 6 3 deform slightly downwards until the middle finger 6 2 in turn comes into contact with the part P.
  • the combination of the rigid element 6 2 and of the two flexible elements 6 1 , 6 3 has the advantage of allowing efficient and reliable bracing of the active part of the anchoring element on the part P.
  • the part P to be clamped is relatively high, it is possible, thanks to the design of the sliders 1, to stack several of these sliders, that is to say to assemble them by sliding in order to constitute stages as illustrated in FIG. 2.
  • the sliders are immobilized mutually by the pins 17 which also serve, as indicated above, for the axial immobilization of the screw 10.
  • These pins 17 are in fact housed in holes 19 passing right through the head of the slide so as to be able to come enter the identical opening provided on the other adjacent slide.
  • the downward movement of the lug 17 is limited by a radial finger 20 integral with this lug and moving in a slot 21 opening onto the front face 12 of the slide.
  • the radial finger 20 is accessible from the outside so as to allow the sliders to be uncoupled by simple upward movement of the lug 17 made possible by gripping the radial finger 20.
  • the stacked slides can be fixed on a sole 22 having in section a shape complementary to the female part of the slide.
  • This sole which can be in the form of a profiled bar punctually has anchoring holes 23 which pass right through it for the passage of fixing screws 24 coming into heels (not shown) provided with holes threaded and housed in the classic T-slots of the machine tool table.
  • These profiled bars or soles 22 can be oriented in a plane parallel to the grooves of the table, in an orthogonal or oblique plane.
  • the user is no longer bound to the shape of the grooves of the table of the machine tool or to their respective spacing and can move these slides at will on the soles 22 and this, whatever the shape of the part. , since said soles can be oriented in different directions.
  • this lateral clamping device with a vertical clamping device such as those described and represented in the patent applications mentioned in the preamble to the application and belonging to the applicant. This would give a cumulative lateral clamping of the part on its side blanks and at different heights, plus a reliable vertical clamping thus allowing machining in complete safety.
