Definitions

  • the invention relates to a mechanical receiving adapter according to the preamble of claim 1; especially with installation of two (force) sensors for the purpose of Measurement signal acquisition for comprehensive quality assurance, in the following abbreviated "QS", preferably in the Crimp.
  • the crimp itself and its execution the tool that shapes and shapes the crimp, the press that runs the tool and the machine, which defines the line to be edited for the Crimping leads and sorted stores.
  • Generic recording adapters are in the crimping technique for example, by cable confectioners for measuring of force courses, which depend on the angle, used by the way, or by time.
  • Such a receiving adapter detects the force curve, during the crimping or crimping of a cable end sleeve applied with an electrical conductor is, and passes a corresponding measurement signal to a electronic evaluation device.
  • crimp connections can be: stranded wire with a ferrule, stranded wire with wire, wire with wire or assembly, stranded wire and other aspects of cable assembly.
  • electrical cables are crimped in the range of signal and control cables with wire cross-sections of 0.07mm 2 up to battery cables of 35mm 2 ; Common processed wire cross sections are in the range of 0.15mm 2 to 2.5mm 2 .
  • the crimp control in the car cable assembly on Widely used and prescribed as the quality of these compounds directly related to protection of human life, e.g. in the safe Contacting for the actuation of airbag, ABS and Brake Assist, for power steering as well as for the Extensive tax management in a car.
  • the data transfer is either wireless or galvanic coupled with a measuring cable.
  • the distance between the MR and the meter is usually dependent from the means of production - a few meters.
  • the measuring method for crimp control is usually based on a comparative measurement.
  • the meter is the Ideal manufacturing process of the crimping process using the Measured value course taught or stored (teachin Fashion). Typical are 5 to 50, preferably 10 Single force curves of acceptable, ie default conventions Crimp connections. From these ten digitized Force gradients that a capable manufacturing process to reflect, becomes a mean force course calculated, the so-called reference curve. This Reference history is stored in the meter.
  • Such a sensor is known from the document DE-A-4 111 404 known.
  • Object of the present invention is therefore, a to provide generic recording adapter, in which all power flux lines are detected piezoelectrically and in Be evaluated in real time. It is further intended the recording adapter easily and uncomplicated Nearly all presses available on the market can be mounted so that this for a wide range of applications can be used for wire cross sections and how a force sensor itself is handled, so calibrated to measure the absolute force can be used can.
  • the mechanical structure is shown in drawing 1.
  • the basic idea of this invention is, all during the crimping process occurring crimping forces that cause deformation the crimp contact contribute completely to capture.
  • the used there mechanical coupling link of the press is replaced through a same-looking and equal functioning Coupling link with implemented force sensors, called as a recording adapter (Measurement-RAM) in the sense of the present invention.
  • the receiving adapter of Fig. 1 to 3 is made of hardened Steel made and vice versa U-shaped. It consists of a top 10 and a bottom 12 of two Force sensors 14, 16 which are mounted in the lower part, and a common signal feed 18 to one of externally accessible connector 20, also in the lower part assembled.
  • the power flow generated by a press enters the Upper part 10, which by means of openings 22 in the Upper part 10 led screws to connect to the press is. Caused by the mechanical separation the power flow exclusively over the two Force sensors in the lower part. From there flows the Force on two ram punches 24, 26 of the lower part 12 in an existing embossing or crimping tool.
  • the upper part 10 is a flat, plane-parallel plate realized.
  • the lower part 12 is a plane, plane-parallel Pressure part with two orthogonal, equal long thighs that train the Rammstempel 24, 26, in which the two force sensors are embedded are.
  • the Power transmission to the crimping tool symmetrical or asymmetric.
  • the two Rammstempel are the same length with a length of about 13mm and are about 30mm apart away; the total height of the flat pressure part is about 17mm, the total height of the adapter is about 29,0mm.
  • the receiving adapter is formed and dimensions that already existing Mounting holes and mounting thread on commercially available Presses for the assembly of the invention Adapters are used. This is particularly easy the conversion of existing presses.
  • the assembly of the adapter to the press is done with two mounting screws completely tension-free over the Top and the holes 22, non-contact from below passed through openings 32 of the lower part 12. These Screws have no part in the assembly in the press Reaction to the power coupling between upper and Lower part, regardless of the applied mounting torque.
  • the geometric dimensions of the quartz force sensors 14, 16 are a height of 5.2mm, a diameter of 14.5mm, the cable connector is a DV connector.
  • the Sensors have an internal bore for M4 or M6 special expansion screws. The sensors become electric installed as a couple with the same sensitivity.
  • the common measuring signal is located on an externally accessible SMC or external mounted connectors Transmission source for a data transfer; see. approximately 3 and FIG. 5.
  • the sensors themselves as well as the electrical wiring are embedded in silicone rubber. This will be Disturbances caused by oil and moisture as well as pollution, avoided.
  • the narrow one Nip also adequately secures the capacitive shielding.
  • a holder 34th provided with kink protection for stabilizing the measuring cable.
  • This adapter is designed so that when symmetrical Power transmission and entprechendem force sensor Forces up to 40kN (40,000N) can be measured.
  • the Resolution is typ. 1 / 10,000th. Measuring range and resolution are dependent on applied sensors.
  • Typical crimping forces are about 2.5 to 3.5 kN for a wire cross section of 0.15 mm 2 , the typical crimping force for 1.0 mm 2 is about 7.0 to 9.0 kN.
