Definitions

  • the present invention relates so general devices to move at least alternately one or more elements back and forth. More specifically, it relates to a compact pilot clamping device, in particular electric, to position, center, tighten or maintain at least one part to work, to treat or to transport. This type of pilot tightening is used, for example, to clamp sheets of chassis in automobile assembly lines.
  • Classic clamping or clamping heads are usually associated with a hydraulic cylinder or double acting tire housed in a casing on which a clamping arm is rotatably mounted, the arm being controlled in rotation by the jack between a clamping position and a loosening position via a sliding rod between two extreme positions.
  • the transformation of the movement the rod in a rotational movement of the arm is made using an articulated linkage.
  • clamping heads of this type with a relatively large size.
  • the clamping which results from such tools is due to a pendulum movement of the clamping arm which, in the case of certain parts to be treated, may result a malfunction of said clamping arm and, consequently, a bad tightening of the part. This can then cause security problems, work piece or several work pieces not being properly tightened and maintained together.
  • clamping heads are also relatively complex. Moreover, the actuation being carried out using cylinders hydraulic or pneumatic, it is not possible to control the stroke of the clamping arm, which most often results in a movement relatively abrupt clamping arm when tightening which can cause danger to users and defects on the parts to be tightened.
  • the first mobile equipment includes a clevis and two clamping elements, such as fingers, pivoting in opposition in the yoke and is moved linearly by a first motor.
  • the second crew includes a sliding sleeve in the body of the device and in which slides the yoke, and a pilot element from which can project by pivoting the clamping elements in order to tighten two sheets against the upper part of the body.
  • the second crew is moved by a second engine to move the two crews, including with the first engine, in the body.
  • the second crew with the first crew is first moved linearly so that the element pilot protrudes out of the end of the body of the device and engages in a hole in the sheets to be clamped. Then the first motor is activated to slide in the opposite direction from the previous one the first crew and especially the elements tightening in the pilot element so that the clamping elements rotate from an extreme position loosening to an extreme tightening position at which the sheets are pressed against the part upper body.
  • the elements of tightening are driven in linear displacement of independently from the pilot element, towards the extreme clamping position, i.e. that they are brought back to the body.
  • the pilot clamping device thus comprises two electric motors, and is therefore heavy, bulky and expensive.
  • the present invention also aims to alleviate the disadvantages of clamping heads by providing a process of linear displacement of two crews remedying the disadvantage of the second motor for move the first motor.
  • a method for moving linearly a first crew between two first positions relative to a second crew, and the second crew between two second positions relative to a fixed body is characterized in that that the first and second crews are movable by a common actuator, the first and second crews can be moved together from one towards the other of the second positions, the second crew is motionless in the body at one of second positions when the actuator moves the first crew between the second positions, the first crew can be moved from one of the first positions towards one of third positions at which the first and second crews are provisionally bound together, the second crew being motionless in the body to said a second position when the first crew is untied from the second crew to the other third positions and is moved from said other third position towards said one second position.
  • the invention also relates to a device for implementing the process according to the invention, comprising a first crew, and a second crew movable in a body.
  • the device such as a clamping device, is characterized in that it comprises a single actuator, first connecting means to link detachably the first and second crews so that the actuator moves linearly together the first and second crews in the body, and second connecting means for binding detachably the second crew to the body so that the actuator moves linearly only the first crew in the second crew motionless in the body.
  • the actuator is only linked to the first crew so much so that the displacements of the second crew can operate so that the first crew pushes the second crew without being tied to first crew from one to the other of the second positions and pulls the second crew by being provisionally linked to the first crew of one the other of the third positions.
  • the only actuator is a jack electric having a screw fixed to the first crew.
  • the single actuator makes the device according to the invention, such as a pilot tightening, and contributes to a reduction in sound weight and cost.
  • First crew races between said a first position and said a third position and between said other third position and said a second position, intended only to link and untie the first and second crews are preferably substantially equal and significantly shorter than the races significantly of the first and second crews together between said first positions and between said first third positions, intended to take out an element device body pilot and bring back jaws located at the ends of elements of clamping against workpieces, sheets or the like tighten.
  • the course of the pilot element, and therefore of the second crew is limited to said second positions to which the second crew is placed abutment against the body in directions opposite.
  • the body of the device then comprises two stops to limit the linear displacement of the second crew.
  • the first crew to said a third position can be abutted against the second crew to link the first crew to the second crew already abutted against the body.
  • the first means of connection can understand a first projection in one of the first and second crews, and a first means of elastic retention attached to the other of the first and second crews to retain said first protrusion as long as the actuator exerts no effort greater than a first predetermined value for separate the first projection from the first means of retention.
  • the first crew includes a piston linked to the actuator, minus a pivoting clamping element, and an axis of articulation between the piston and the element of tightening, the first projection being one end of the axis of articulation.
  • the second means of connection can have structure and arrangement similar to the first means to reduce manufacturing costs.
  • they include a second projection in one of the second crew and corps, and a second elastic retention means attached to the other second crew and corps to retain said second projection as long as the actuator does not exercise effort greater than a second value predetermined to separate the second projection from second means of retention.
  • the second projection is one end of a pin crossing a light from an element of tightening in the first crew, and having a portion parallel to the direction of travel linear of the crews and a portion, for example curvilinear, secant to said direction of travel linear.
  • the pin passes through the pilot element of the second crew in which the clamping element slides pivotally and which is in abutment against the body when said pin is retained by the second means of elastic retention.
  • the first predetermined value effort is higher than the second value predetermined effort so that the second crew be linked to the body during the displacement of the single first crew and be released from the body while remaining linked to the first crew in order to fire together the first and second crews and so enter the body the pilot element with the element Clamping.
  • each of the first and second elastic retention means is tweezers.
  • a tweezer is attached to one end of a light in which the axis joint or the pin is moved.
