Definitions

  • the invention relates to a multi-axis table with a modular system, which is mounted on a pivotable about a horizontal axis and rotatable about a vertical axis pallet of a multi-axis, for controlling and actuating hydraulically acting working cylinders, which are associated with devices for clamping workpieces, with a module hydraulic valve having a hydraulic input, a hydraulic output for a working cylinder and a valve for pressurizing the hydraulic output, wherein the valve in a non-energized state sealingly blocks the hydraulic output, and wherein the module is associated with a control for selectively driving the valve.
  • the DE 25 00 096 A1 relates to a circuit arrangement and shows a valve with two working ports and a control port. In this case, the control of the valve by means of a control plate takes place.
  • a modular system in which various channels are arranged in a circuit board, which are connected to arranged on the board Zuschaltventilen in such a way that when pressure build-up in a predetermined order the Zuschaltventile actuate working cylinder for clamping workpieces.
  • the advantage of the known modular system is that by a suitable interconnection of the additional valves by means of the channels of the desired workflow with a small number of hydraulic supply lines can be achieved.
  • a disadvantage of the known modular system is that when changing the tasks, ie the channel layout of the boards or the arrangement of the additional valves must be changed in a different switching order.
  • the problem underlying the invention is to provide a modular system with which complex switching operations can be provided flexibly and as needed in a simple manner with simple construction and few hydraulic supply lines, wherein the modular system should also be usable in movable or rotating elements.
  • the problem is solved in that in a multi-axis table with a modular system of the type mentioned several modules, energy transmission elements and signal transmission means and a connector for supplying electrical components of the module system and providing a bidirectional signal transmission by means of a non-contact or by sliding contacts realized power supply and transmission of Control signals and / or sensor signals.
  • modules can be provided in the module system, which are each controlled randomly.
  • the respectively required hydraulic pressure can be provided via the same hydraulic supply line, since after carrying out the respective clamping or switching operation by actuating the valve for returning to the non-excitation state, the hydraulic pressure is held for clamping because the valve seals the hydraulic output. It may be provided a common control for several modules.
  • a development of the invention is characterized in that a common hydraulic connection is provided for a plurality of modules. In this way, a plurality of modules of the modular system can be acted upon with hydraulic pressure with a single hydraulic connection.
  • the common hydraulic connection may preferably have a rotary distributor. This makes the arrangement also possible on rotating components, such as rotating pallets or workpiece carriers.
  • valve is a seat valve.
  • a seat valve reliably ensures that when driving the valve in its non-excitation state, the hydraulic output is sealingly locked.
  • pressure-adjusting means are provided for the hydraulic pressure.
  • a pressure switch or a pressure sensor can be assigned to the hydraulic output for the pressure actuating means.
  • an aggregate for supplying the hydraulic input has the pressure adjusting means.
  • the pressure switch can lock the hydraulic line when reaching a predetermined pressure by means of the control or switch the valve in its non-excitation state.
  • pressure signals can be detected and passed on to a controller, so that when reaching the predetermined pressure, the valve is switched to the non-energized state.
  • the unit has the pressure-adjusting means, the pressure assigned to the respective working cylinder can be adjusted by the pressure-adjusting means for the given switching operation and relayed from the valve to the working cylinder. Because, according to the invention, individual modules can be controlled separately, it is thus possible to ensure that each working cylinder is assigned the respective predetermined hydraulic pressure, without thereby affecting other working cylinders.
  • the pressure actuator of the unit may, for example, have a proportional pressure relief valve.
  • the controller is programmable.
  • the controller may include a processor.
  • the module system according to the invention can be adapted to a large number of tasks with little effort.
  • standardized components can be used for many applications. This greatly simplifies planning.
  • the programming of the controller can be achieved particularly simply by using maintenance and / or set-up software for programming the controller by means of a computer. In this way, the individual programming steps can each be prefabricated in such a way that, when a specific operating state is selected, the corresponding subroutines are automatically combined.
  • the energy transmission element transmits the energy inductively and / or capacitively.
  • the hydraulic pressure by means of a hydraulic generator is used to generate energy, which generates electrical energy from the hydraulic pressure.
