Definitions

  • the present invention relates to a workpiece carrier for receiving a plurality of workpieces.
  • the workpiece carrier can in particular be designed in the manner of a basket (for example as a metal basket or wire mesh basket) and is therefore also referred to below as a workpiece basket.
  • Such a workpiece carrier comprises a flat base element in the form of a horizontally arranged perforated plate and a plurality of interchangeable workpiece holders, which are inserted into the openings of the perforated plate.
  • workpiece holders for a wide variety of shapes and dimensions of the workpieces available.
  • Each workpiece holder forms a rigid unit and comprises a single Positioning element (eg, a single vertically projecting pin or cone) or a plurality of spaced apart positioning elements (eg in the form of four vertically upwardly projecting pins).
  • a similar solution with exchangeable workpiece holders is shown in DE 10 2011 108 725 B4 in FIGS. 19 to 21, wherein a wire grid serves as the basis here.
  • a (preferably basket-like) workpiece carrier for receiving a plurality of workpieces, which has
  • each workpiece holder comprising at least two positioning elements for positioning the workpiece, wherein the positioning elements are arranged at a distance from one another.
  • the horizontal distance of the positioning of each workpiece holder is mutually variable.
  • the workpiece carrier has a displacement element, which is arranged horizontally displaceable relative to the base element along a longitudinal direction.
  • the positioning elements interact with the base element and the displacement element in such a way that a displacement of the displacement element relative to the base element along the longitudinal direction causes a simultaneous change in distance of the positioning elements of a plurality (preferably all) of the workpiece receptacles to one another.
  • Such a workpiece carrier is very simple. He can construct very flat. The adjustment of all workpiece holders can be done simultaneously by a single adjusting device which moves the displacement element relative to the base element. This allows a very quick and easy adjustment.
  • the positioning elements may be e.g. act around simple pins pointing in the vertical direction; but they can also be more complex elements, e.g. Centering jaws with complex contours such as step contours or conical areas, or with a mold adapted in any other way to specific types of workpieces.
  • Each workpiece holder preferably defines a centering center of the workpiece holder, and the positioning elements cooperate with the base element and the displacement element in such a way that the centering center of each workpiece holder remains unchanged with respect to the base element when there is a change in distance of the associated positioning elements.
  • the centering center is understood to be the geometric center of the positioning elements. If, for example, all positioning elements of a workpiece holder in a first position of the displacement element have the same distance from the centering center of the workpiece holder, then the positioning elements preferably shift during a displacement of the displacement element such that the distance from the centering center changes by the same amount for all positioning elements that furthermore the distance from the centering center is identical for all positioning elements.
  • the shift extend in the radial direction along straight lines, which intersect the centering center, relative to the base element; but the displacement can also be in other straight or curved directions.
  • at least one of the positioning elements of each workpiece holder is displaceably guided both along the base element along a first guide direction and on the displacement element along a second guide direction, wherein the first guide direction and the second guide direction differ from one another. If both the first guide direction and the second guide direction extend obliquely to the longitudinal direction, a displacement of the displacement element relative to the base element along the longitudinal direction causes a displacement of the respective positioning element both relative to the base element and with respect to the displacement element.
  • the first and second guide directions can each run straight (linear) or gel irrimt. If both guide directions are straight, one can also express the above situation as follows: The first guide direction extends at a first angle to the longitudinal direction, and the second guide direction extends at a second angle to the longitudinal direction, wherein the first angle and the second angle differ.
  • the amount by which the positioning element shifts with respect to the base element along the first guide direction when the displacement element is displaced by a given amount along the longitudinal direction can easily be determined by the course of the second guide direction given the first guide direction or given a first angle or by selecting the second angle.
  • the first and the second angle are each between 15 ° and 75 ° (absolute value).
  • the difference between the first and second angles is preferably between 15 ° and 165 °, more preferably between 30 ° and 150 °.
  • each workpiece holder comprises at least three (preferably exactly three) positioning elements, which are arranged radially around the centering center of the workpiece holder and symmetrical with respect to this Centering are displaced. At least two (preferably exactly two) of the positioning elements are then preferably displaceably guided, in each case in the manner described above, both on the base element and on the displacement element.
  • Each of these two positioning elements is thus both on the base member along an obliquely to the longitudinal direction (in the case of a linear displacement at a first angle to the longitudinal direction extending) associated first guide direction and on the displacement element along an obliquely to the longitudinal direction (in the case of a linear displacement in a second angle to the longitudinal direction) associated second guide direction slidably guided, wherein the associated first guide direction and the associated second guide direction differ (in particular the first angle and the second angle differ).
  • a displacement of the displacement element relative to the base element along the longitudinal direction causes a displacement of the respective positioning element relative to the base element along the first guide direction.
  • the first guide directions and the second guide directions are then selected for the relevant positioning elements such that a displacement of the displacement element relative to the base element causes a displacement displacement of the positioning of the respective workpiece holder relative to the base member by a displacement of identical amount, in such a way the centering center of the workpiece holder remains unchanged relative to the base element.
  • first and second guide directions of two positioning elements in each case with respect to each other with respect to the displacement direction are mirror-symmetrical.
  • the first angle has a value of 60 ° and the second angle has a value of 30 ° and that for the other of the positioning elements the first angle has a value of -60 ° and the second angle a Value of -30 ° has.
  • the first guide directions of the two positioning elements enclose an angle of 120 ° to one another, while the second guide directions enclose an angle of 60 ° to one another.
  • the third positioning element is stationary relative to the displacement element, in particular rigidly connected to the displacement element, but displaceable parallel to the longitudinal direction relative to the base element along a third guide direction.
  • the leadership of the three Positioning elements should then cut in the center of the workpiece holder.
