Definitions

  • the present invention relates to the field of the wood industry, in particular the manufacture of furniture, in particular of boxes, and relates to a device for tightening frames.
  • the existing frame clamping devices generally consist of a frame of rectangular section inside which are mounted, with the possibility of displacement, at least one vertical element for clamping the vertical edges of the frames to be assembled and a horizontal clamping element. horizontal edges of the frames on the lower frame member (DE-A-1196844).
  • Devices of the latter type may have one or more horizontal elements displaceable from the upper horizontal spar towards the lower horizontal spar of the frame by means of a mechanism of the Saint Andrew cross type or by means of linear drives acting on the ends of the said horizontal element or elements.
  • These devices can, in addition, also be provided with means for clamping the vertical edges in the form of vertical elements. also displaceable with respect to the uprights of the frame by means of a mechanism of the Saint-André cross type or by means of linear drives acting on the ends of these vertical elements.
  • the automatic adjustment clamping devices certainly allow rapid adjustment of the settings according to the frames to be produced, but are, however, of a very high cost price which is incompatible with a small manufacturing volume.
  • a frame clamping device having vertical clamping elements displaceable on a horizontal beam and provided with stops preventing their tilting, in one direction, beyond an angle of 90 °. .
  • These vertical clamping elements are movable by sliding on their upper stop and can be tightened by means of pins.
  • the operation of these elements is however relatively delicate and painful, their easy and precise sliding, with a view to positioning, on the horizontal beam being difficult to perform and requiring relatively large muscular expenditure.
  • these elements do not allow rapid clamping of parts together.
  • the present invention aims to overcome these drawbacks.
  • a clamping device for frames constituted by a frame for receiving the frames, by a means for clamping the horizontal edges of said frames and by a means for clamping the vertical edges of the frames constituted by a mounted arm movably on the upper side member of the frame and provided with a locking device in the operating position, characterized in that the device acts by bracing and is constituted by two stops mounted, one on the face of the turned arm towards the frame, above the upper side member of the frame and the other on the opposite side of the arm below the upper side member of the frame, in that the arm forming the means for tightening the vertical edges of the frames is integral with a rolling chassis on the spar equipped with two grooved rollers whose cheeks surround the spar, said chassis being constituted, on the one hand, by a horizontal element integral with the upper end of the arm and carrying the the rollers and, on the other hand, by a tie connecting the free end of the element to the arm, substantially in its lower half, and in that the rollers of the rolling chassis
  • the frame clamping device 1 which is constituted by a frame 2 for receiving the frames 1, by means 3 for clamping the horizontal edges of said frames 1 and by means 4 for clamping the vertical edges of frames 1, which 1 is constituted by an arm movably mounted on the upper spar 5 of the frame 2 and provided with a device 6 for locking in the service position by bracing.
  • the device 6 for locking in the service position by bracing advantageously consists of two stops 6 ′ and 6 et mounted, one, 6 ′, on the face of the arm 4 facing the frame 1, above the side member upper 5 of the frame 2 and the other, 6 ⁇ , on the opposite face of the arm 4 below the upper spar 5 of the frame 2.
  • the arm 4 forming the means for clamping the vertical edges of the frames 1 is integral with a rolling chassis on the spar 5 fitted with two grooved rollers 7 whose cheeks surround the spar 5, said chassis being formed, on the one hand , by a horizontal element 8 secured to the upper end of the arm 4 and carrying the rollers 7 and, on the other hand, by a tie rod 9 connecting the free end of the element 8 to the arm 4 substantially in its lower half.
  • the rollers 7 of the rolling chassis are advantageously mounted on the horizontal element 8 of the latter with an offset in height of their axes, the axis of the roller 7 furthest from the arm 4 being arranged at a higher level on the element 8 than the axis of the roller 7 closest to the arm 4 and the stops 6 ′ and 6 ⁇ are arranged on the arm 4 with a spacing corresponding to the height of the spar 5, in the service position of the arm 4, the roller 7 closest to the arm 4 being slightly raised from the beam 5 in this said service position.
  • the spacing between the opposite faces of the stops 6 ′ and 6 ⁇ being equal to the height of the spar 5 in the clamping position of a frame 1 by arc -boutement, that is to say the stops 6 ′ and 6 ⁇ each bearing on one side on said spar 5 and the roller 7 farthest from the arm 4 being lifted from the spar 5, the nearest roller 7 of the arm 4 being slightly raised from the beam 5, when the arm 4 returns to the non-use position, there is a pivoting of the arm 4 and rolling frame assembly around the axis of the nearest roller 7 of the arm 4, after its support on the spar 5, having the effect of spreading said abutments 6 ′ and 6 ⁇ from their fulcrum on the side member 5.
  • the arm 4 is provided at its free end with a jack 10 for bearing on the edge of the lower part of the frame 1 to be clamped and the means 3 for clamping the horizontal edges of the frames 1 is constituted by one or several jacks 12 with vertical action, the piston rod of which rests by means of a horizontal bar 13 on the upper edges of said frames 1.
  • the arm 4 can be provided with one or more jacks 11, movable vertically, for clamping the edges vertical of the frame 1, the displacement of these jacks 11 being carried out by means of other jacks with vertical displacement, or by manual adjustment.
  • jacks 11 movable vertically, for clamping the edges vertical of the frame 1, the displacement of these jacks 11 being carried out by means of other jacks with vertical displacement, or by manual adjustment.
  • the device according to the invention is implemented by simply moving the arm 4 together with its running chassis on the spar 5 of the frame 2 in the direction of the frame 1 to be tightened until the actuator 10 reaches the stop, equipping the free end of the arm 4, against the lower part of the vertical side of the frame 1.
  • an arm 4 bracing is carried out on the stops 6 ′ and 6 ⁇ .
  • the bracing effect obtained is increased when the jack 10 and the jack (s) 11 are pressurized, the clamping force exerted by the latter resulting in a theoretical pivoting torque around the stops 6 ′ and 6 et and consequently increasing their bearing force on the corresponding faces of the spar 5.
  • the arm 4 or its rolling chassis can be provided with a movement control device in the form of a jack whose stop is controlled by a probe located near the actuator 10 fitted to the free end of the arm 4.
  • the operator need only control the actuation of the displacement actuator of the arm 4, the actuation of this actuator taking place automatically when of the actuator 10 abutting against the frame 1 to be tightened. It is thus possible for the operator to carry out any manipulation with two hands before the arm 4 comes into abutment.
  • the device according to the invention makes it possible to quickly and effectively tighten the vertical edges of frames to be assembled and to adapt them instant of the means for clamping the vertical edges of the frames to the dimensions of the latter.
