Definitions

  • the invention relates to a device for checking at least one receiving part and one of these partially absorbed and by material deformation with the receiving part connectable workpiece, the Work piece over a top of the receiving part survives certain protrusion.
  • a device for checking at least one receiving part and one of these partially absorbed and by material deformation with the receiving part connectable workpiece, the Work piece over a top of the receiving part survives certain protrusion.
  • Such a device is especially for mechanical mechanical Material deformation thought.
  • the invention has for its object a device of the type mentioned at the beginning, with which improved quality assurance, what the each other affects parts to be connected by material deformation, is achievable.
  • the workpiece to be deformed and the at least one receiving part, that which is to be deformed Takes up workpiece or that of the one to be deformed Work part is penetrated by means of separate Sensing organs detected.
  • a first moves Stylus starting from a starting position in the direction towards the recording part in order to after a replacement first contact the receiving part. In At this moment the further advance of the first probe organ prevented.
  • the driving force, with that the first probe is advanced is by far not sufficient to make the first contact Deforming or damaging the receiving part.
  • Means a second probe becomes the part to be deformed Workpiece scanned. The second probe moves also starting from a starting position in the direction towards the workpiece after it has been replaced to contact a second route.
  • the path difference is determined with the protrusion dimension compared to the workpiece to be deformed over the at least one receiving part or, in the case of several receiving parts via the uppermost one closest to the sensing elements Receiving part survives; because with the two touch organs is the one facing the two sensing elements Top of the arrangement of to be deformed Workpiece and receiving part or receiving parts approached been.
  • the determined path difference represents that Actual protrusion measure. Is the path difference with the predefined (target) projection dimension, can decided taking into account a tolerance range whether the actual protrusion dimension is more than that Tolerance range deviates from the target overhang dimension.
  • the path difference can be determined that from both probes starting from their starting positions to a standstill distances traveled are measured in each case and then the difference in distance traveled Distance is determined, including the relative location their starting positions must be known.
  • a alternative procedure for determining the path difference consists only of that distance to measure by which the two probes are compared have moved to their home positions until they stand still. For example, is the distance between the two Sensing organs known in the direction of their movement (relative position their starting positions), can be Odometer showing the relative movement of a probe on the other hand measures the path difference directly be measured.
  • the leading (first) feeler organ if present contacted by workpiece and receiving part first, in Direction of the receiving part and workpiece resilient on second probe and / or on one holding it Holding element is mounted and that the second probe is driven. Then the first probe comes in Contact with the receiving part, so it becomes relative to the further advancing first probe, which has not yet reached the workpiece. This distance is then measured by the encoder detected. Taking into account the relative position the starting positions of the two sensing elements (distance the same in the direction of movement in the starting position) and the return movement of the first sensing element relative to the second can then be the actual overhang dimension of the workpiece can be determined via the receiving part.
  • the standstill of a sensing element is expedient determined that the output signal of a measuring the advance of the relevant sensing element No longer changed.
  • a detector is sufficient to determine mechanical Tensions when the distance the spring-mounted probe organ the other in the direction of movement considered premature, is larger than the expected Projection of the workpiece relative to the receiving part.
  • the very decisive advantage of the invention Device is that the invention is immediate in a deformation machine, for example a riveting machine can be realized. Doing so the deformation or riveting tool the function of (Second) sensing element for detection of the material to be deformed Workpiece or rivets. On the one carrying the riveting tool The rivet head is then relative to this in the direction of movement the other (first) feeler is slidably mounted arranged. The contact area of the first Probe organ rushes to the side with which the riveting tool strikes the rivet by more than the expected overhang dimension.
  • the actual deformation the rivet in particular takes place when moving Riveting tool this is either a wobble (Wobble riveting process) or along a trochoid, especially a hypotrochoid (Radial riveting) moved.
  • the feed force, with which the riveting tool up to the rivet is moved forward, can be equal to the pressing force with the moving riveting tool against the rivet is pressed.
  • the riveting tool can also be used a lower force to the rivet will. But it is also possible without movement the riveting tool, i.e. with the riveting tool stationary, to deform the rivet by a pure pressing process.
  • the invention is also applicable in this case.
  • each the Can measure the total distance of the two sensing elements also a path encoder to determine the total distance one sensing element and the other displacement sensor for determination the relative distance of both probes used will.
  • the starting position of the are known a probe organ, the total distance of which is measured is, as well as the offset of both tactile organs in the direction of movement and in the starting position of both feelers.
  • Based on the measured total distance of the one sensing element the extension of the person contacted by him Part (workpiece or receiving part) are determined while taking into account the covered by both probes at standstill Relative distance and the measured distance Extension of the other part (receiving part or workpiece) determined in the direction of movement of the sensing elements can be.
  • the one that remains scanning the workpiece remains Probe also during mechanical deformation of the workpiece in contact with it. From the beginning the mechanical deformation then becomes the additional path measured, which continues with a certain pressing force applied to the workpiece second probe due to the compression of the workpiece covered in the direction of movement of the feelers. Becomes a predetermined target additional distance before a also reached the specified minimum time period or until the end of a maximum period, which is longer is not reached as the minimum period, then issued an error message.
  • This error message says that the material of the workpiece to be deformed too soft (covering the additional distance before expiry a minimum time - minimum time period) or is too hard (Even if a maximum period of time has elapsed, the target additional distance is not covered by the second probe been). With this review you can thus statements about the quality of the material of the workpiece do.
