Definitions

  • the object of the invention is to provide a sonotrode feed unit for ultrasonic workpiece machining, for example, the less high frequency Shielding and voting problems with simple ellatechni ⁇ shear concept has.
  • a high-frequency line connection for supplying the converter with energy between the generator and the converter is substantially rigid and covered to the outside.
  • the mobile coupling of the generator together with the converter and / or the sonotrode enables the use of cable connections which are not moved even in the feed phase. This prevents line breaks, disconnected switches, etc.
  • the high-frequency generator and the converter in a common housing is arranged ange ⁇ integrated. On the one hand, this allows a particularly compact design. On the other hand, in addition, the cable between the converter and the generator is protected from damage to the outside.
  • the generator can furthermore be connected or connectable to a feed line and to a control line, which are arranged in a common cable. In this way, leads from the converter and the generator housing containing only an electrical line to the outside.
  • the housing may also be provided with a display and / or with a control panel. This is particularly easy due to the arrangement of the generator in the housing. An operating unit on the housing is particularly intuitive for the user. In the case of large plants, fault finding is possible at a glance directly at the unit of welding.
  • the high-frequency voltage for the converter 7 is generated by a high-frequency (HF) generator 9, which is flange-mounted in the immediate vicinity of the piston-cylinder drive 3 on the side of the base 2 facing away from the longitudinal guide 4.
  • HF high-frequency
  • To transmit the high-frequency voltage from the RF generator to Kon ⁇ verter 7 is the shielded RF cable 10, which are provided due to the spatial proximity of the RF generator 9 to the converter 7 particularly short and with little length to compensate for Sonotroden- delivery movement can.
  • the power supply of the HF generator 9 is gesi ⁇ chert via a standard power cord 11. Even a low-voltage supply is possible.
  • the converter 7 is provided with connection points 15.
  • the generator 9 is provided with connection points 16.
  • Kirsleitun ⁇ conditions 12 between the connection points 15, 16 may be due to the arrangement of converter 7 and generator 9 in a common housing very short, typically less than 20cm long sure ⁇ forms.
  • a short length of the line connection 12 is also obtained if a secondary-side connection 17 of the transformer (not specifically shown) of the generator 9 is closer to the connection points 15 of the converter 7 than the connection of the primary side 18 of the transformer.
  • HF generator 9 and converter 7 creates an extremely compact sonotrode unit 1 ", in which the usual high-frequency problems can be optimally reduced due to a conceivably close association of the two aforementioned components.
  • the HF generator 9 (possibly with converter 7) consist of a correspondingly populated board (see also FIG. 5), which is inserted into a housing, preferably made of aluminum with integral cooling fins.
  • the feed unit 1 '" is also provided with a displaceable limit switch 25, which defines the lower end position. Similarly, an upper limit switch (not shown) can be provided. In addition, the feed unit 1 '"is provided with a stroke limitation 26.
  • an adapter plug 23 is shown schematically.
  • the adapter plug 23 is inserted between the control and power supply unit, not shown, and the plug 22.
  • the adapter plug 23 permits the measurement of parameters, for example the power consumption of the generator 9, which can not be measured / displayed by the generator 9 itself. For reasons of cost and space it is attempted to make the generator 9 as simple as possible. Measurement arrangements for parameters which are not determined by default can thereby be outsourced in a simple manner to such a measuring adapter 23, which can be used variably for a plurality of feed units according to the invention.
  • the adapter plug can be provided with display elements. He may also have a memory with which measurement data can be transmitted in a computer.
  • the adapter can also be connected directly to a computer via suitable interfaces.
  • FIG. 5 shows an exploded view of the feed unit 1 '' 'according to FIG. 4a.
  • FIG. 5 shows a circuit board 27 of the generator 9.
  • the housing 14 made of aluminum is shown, which at the same time serves for receiving and holding the generator, for its protection and shielding, and in particular also for cooling.
