Definitions

  • the invention relates to a pallet changer according to the preamble of patent claim 1.
  • Cooling lubricants are usually supplied during the machining of workpieces, on the one hand to increase the stability of the tool through cooling and lubrication and on the other hand to dissipate the heat introduced into the workpiece and into the tool as quickly as possible from the machining point.
  • the automotive industry has started to use engine, chassis or body components made of light metals, preferably of aluminum or magnesium alloys.
  • the processing of such magnesium-containing alloys is, however, relatively problematic, since the processing chips are easily flammable, so that a relatively high effort has to be made to maintain the required production security.
  • the use of cooling lubricants based on water-based bases is only possible to a limited extent, since magnesium reacts with these components, so that oil-containing cooling lubricants must be used.
  • oil-containing cooling lubricants frequently adhere to the workpiece to be machined, so that it has to be cleaned with suitable cleaning agents after machining.
  • the agents used for cooling and cleaning have to be disposed of or separated after the processing / cleaning cycle, which is relatively expensive.
  • the machining in the processing chamber can still take place under inert gas, so that operational reliability is increased.
  • Such machining centers for drilling and milling are expanded into flexible production cells by equipping them with pallet changers and pallet stores.
  • pallet changing devices a basic distinction is made between pallet changers with a linearly acting pallet shifting station and pallet changers which are designed as swivel changers. Both systems work with at least two pallets, one of which is in a machining position in which it is clamped on a workpiece carrier, and the other in a transfer position in which a workpiece to be machined is clamped, which is then processed after machining the one workpiece can be swiveled into the machining position without a time delay. These measures reduce the chip-to-chip time compared to machine tools without a pallet changer.
  • a machining center 1 shows a plan view of a machining center 1 in which a spindle carrier 2 which can be moved in the X and Y directions (perpendicular to the plane of the drawing) is guided by a cross guide on a nem stand 4 is guided.
  • the spindle carrier 2 carries a horizontal work spindle 6 for receiving a machining tool.
  • the machining center 1 also has a tool changer, which can be designed, for example, as a drum magazine 8 arranged laterally, in which the tools 10 to be fed to the work spindle 6 are accommodated.
  • a tool changer which can be designed, for example, as a drum magazine 8 arranged laterally, in which the tools 10 to be fed to the work spindle 6 are accommodated.
  • a workpiece carrier (table) 12 of the machining center 1 is mounted on a machine bed, not shown, in the feed direction (Z).
  • the workpiece carrier 12 and the work spindle 6 are surrounded by a machining chamber 14, so that dry machining is made possible.
  • a pallet changer 16 is assigned to the workpiece carrier 12, in which two pallets 18, 20 are mounted on a swivel device 22.
  • the pallet 18 In the position shown in FIG. 1, the pallet 18 is in its processing position, in which it is clamped on the workpiece carrier 12 by means of suitable clamping means.
  • the other pallet 20 is located in a loading area in the transfer position, in which a previously machined workpiece can be removed and a workpiece to be machined can be clamped.
  • the pallet changer 16 carries a swing door 26, hereinafter called partition 26. Together with the side walls 15 and the arcuate walls 24 of the processing chamber 14 which are curved in a circular arc, this forms a complete encapsulation of the working area, which permits wet and dry processing.
  • the pallet changer 16 has furthermore an arcuate sliding door 25, which closes a loading area for the pallet 20 and which serves as operator protection when changing the pallet.
  • the partition wall 26 lies sealingly against the peripheral wall 24, so that the space in which the pallet 18 located in the processing area is located is separated from the workpiece loading area in which the other pallet 20 is arranged.
  • the closed processing chamber 14 is thus limited by the side walls of the cabin which extend along the guide for the workpiece carrier 12, the upper half of the peripheral wall 24 and the partition wall 26 in FIG. 1.
  • the latter is mounted on the swivel device 22, so that the partition 26 is rotated by 180 ° when the pallets are swiveled.
  • a disadvantage of the embodiment shown in FIG. 1 is that the volume encompassed by the peripheral wall 24 and the partition wall 26 is comparatively large, and reliable removal of chips from the processing chamber 14 is difficult.
  • the invention has for its object to provide a pallet changer in which the processing space is reduced to a minimum.
  • the circumferential walls and the partition wall are pivoted together by the measures according to the invention, so that the geometry of the peripheral walls is no longer adapted to the pivoting radius of the partition wall. that must, but can essentially be designed according to the pallet shape, so that the space encompassed by the peripheral walls is reduced to a minimum.
  • the processing chamber can thus be considerably reduced in size compared to the conventional solution, so that the dead space of the processing chamber is less and thus chip removal is facilitated and the risk of ignition is reduced.
  • the partition and the peripheral wall jointly form an H-shaped body, the two legs of the H being formed by the peripheral walls and each encompassing one of the two pallets at a small parallel distance.
  • peripheral walls and the partition wall are formed in one piece, so that no sealing problems occur in the transition region between the partition wall and the peripheral wall.
  • the side edges of the H-legs are provided with sealing edges and, together with the side walls of the cabin surrounding the workpiece carrier guide, form a closed processing chamber.
  • the side walls are formed by two U-legs, which are displaceable along their longitudinal axis with respect to the partition, so that the two U-legs can partially encompass one of the two pallets.
  • an H is formed by the longitudinal displaceability of the two U-legs over a pallet changing cycle, so that practically the same principle is used as in the solution described above.
  • the U- or H-shaped pallet door consisting of a partition and associated peripheral walls, can be means of a lifting device in the vertical direction from a straightening position so that the pivoting can take place without sliding the peripheral edges on the cabin floor.
  • the construction is particularly simple if the above-described door of the pallet changer is provided with telescopic sections on which the lifting device engages, so that not the entire door but only the telescopic sections are raised.
  • this area can also be formed with telescopic sections of the door, on which an actuating device acts for lowering, so that the door can be freely pivoted together with the pallets, without on the roof or the To rest the contact surface of the processing chamber.

This means that the pallets are encompassed by the adjacent sections of the peripheral walls 48, 50 and by the partition wall 46, so that the section of the pallet 20 pointing towards the viewer and the section of the pallet 18 pointing towards the work spindle remain open.
