Definitions
- the invention relates to a fastening device according to the preamble of claim 1 (see EP-A-989 636).
- Generic fastening devices are known in principle and serve, for example, one or more claw-shaped Bend tabs around a conductor or through parts of one To drive conductor such that an electrical Contacting and at the same time securing the contact is brought about.
- a device which for Quality control of a crimp connection is used.
- the used Crimping tool has a movable upper tool, which is guided on a housing. During the crimping process the maximum value of the applied force is measured and compared with a stored value. In the event of a deviation from the stored setpoint becomes a Error message issued.
- the fastening device is a force measuring device for Determining a reaction force is assigned, which is a Control unit with a programmable memory has stored setpoints and a comparator, and that the measured reaction force after each Tool stroke is compared with the stored setpoints.
- the invention thereby allows an accurate and automatic Quality control. A deviation between the measured value and Setpoint indicates connection errors, which are their cause for example in a crimp that is not (completely) closed or damage to the conductor (punching or Kinking of individual strands).
- the signal can be used for a optical display can be used. However, it is the same conceivable to send the signal to an automatic device, which to select, in other words scrap or Rework parts.
- each setpoint is with an upper and one provided lower tolerance range, so that a Tolerance band for the setpoints results. It is understood that the Loss work depending on different Acceleration or different friction ratios can fluctuate.
- the driven tool part made of lightweight materials low specific density.
- the invention is based on a preferred exemplary embodiment, which consists of two figures emerges, described in more detail.
- the figures each show in perspective view and reduced one Fastening device according to the invention, according to Figure 2 without electrical attachments.
- the fastening device 1 comprises a Upper tool 2 and a lower tool 3 with a foot 4 and a basic body 5.
- the foot 4 serves as a support and clamping on a machine table, not shown (for example a press) and the basic body 3 is firmly on the foot 4 arranged.
- Between the upper tool 2 and the lower tool 3 are also linear guide means 6 provided so that the two tool parts 2, 3 relative are movable towards each other.
- the upper tool 2 is not one of the exemplary embodiments shown press ram driven, and a top Pin 7 is used to clamp the upper tool part 2 in the Stoessel.
- the fastening device 1 also has via a force measuring device 8 for measuring the acting Reactive force in the operation of the fastening device 1 and via a control unit 9, which is a programmable Memory 10 with stored setpoints and one Comparator 11 includes.
- the force measuring device 8 does not have to must be arranged on the lower tool part 3, but can also be on the press.
- a force sensor 12 is a load cell or simple strain gauges, which in the sense of a Bridge circuit (Wheatstone bridge) for measuring Forces are used. It should also be pointed out that only the reaction forces, i.e. those forces are measured which are opposed to reshaping. To naturally also include acceleration forces and Frictional forces of the tool 2.
- the share of losses is usual Slideways of various influencing factors, such as for example, the lubrication and also the temperature.
- a linear guide with rolling bodies unifies the Loss share regardless of the influencing factors mentioned.
- the specified setpoints are shown with upper ones and lower tolerance ranges, and with the Measured values compared. As soon as a reading as not has been identified correctly, a signal is emitted and, if necessary, the selection of the corresponding production part.
- the linear guide is provided as a module, which consists of at least two parts movable relative to each other and the intermediate Waelz bodies exists.
- Each of the tool parts 2, 3, but especially the driven tool part (according to the figure Upper tool 2) has a frame-like, in comparison with a full body weight-reduced structure. This is for example, by using a honeycomb or grid structure or just simply by correspondingly light and high-strength materials can be implemented.
