Definitions

  • the invention relates to a grinding machine with a grinding unit arranged on the machine bed, the position of which can be changed by turning and / or moving such that the grinding spindle required in each case can be effective for various grinding operations.
  • a wide variety of grinding units having grinding spindles are known. A complicated construction is described for example in DE-PS 31 33 488.
  • the grinding unit is rotatable about a first vertical axis and adjustable about a second horizontal axis. Three different grinding wheels can be brought into engagement with the workpiece.
  • DE-A-820 519 describes a turret lathe which has a turret head on which both a plurality of machining tools and loading and unloading devices are arranged.
  • the loading and unloading devices consist of two separate stations, which are stationary next to each other over the circumference of the turret, like the processing stations. Because of this arrangement and the necessary movement of the relatively large mass of the entire turret, the movement sequences allow a minimum time for one working cycle.
  • the invention has for its object to provide a simply constructed workpiece feed and removal device and to design such that the movement of machine elements in the machining area of the machine tool, which is required anyway, and thus also the drive means already present, can be used directly and in a very short cycle time for the workpiece change .
  • a workpiece feed and removal device is mounted on the grinding head, which consists of a turntable with several (at least two) workpiece receivers distributed over the circumference.
  • FIG. 1 and 2 is a grinding unit which has the four grinding spindles 2, 3, 4 and 5 mounted in the four corners of a square base plate 1 rotatable about the axis A in such a way that a rotation of the Base plate is brought to the workpiece by 90 o each time a different grinding wheel 6, 7, 8 or 9 in the basic grinding position.
  • the grinding process takes place in the usual way and therefore does not have to be described in more detail.
  • the principle of the present invention is illustrated in FIG. 2.
  • the workpiece loading unit 10 is mounted on the base plate 1. It is also rotatable and has the two expanding mandrels 11a and 11b, which run at right angles to one another and can be inserted into the bore of a workpiece 12 and accommodate it.
  • Base plate 1 and workpiece loading device 10 can be coordinated with one another in such a way that automatic workpiece feeding and removal as well as grinding of the clamped workpiece can take place.
  • the machine and control means available for the grinding unit with several grinding spindles can also be used for the workpiece loading device with little effort.
  • Figures 3 and 4 show another embodiment.
  • the base plate 14 with the two grinding spindles 15 and 16 is linearly displaceable, as the arrows indicate.
  • the grinding spindle 16 is replaced by the workpiece loading device 17, which has two mutually opposite expanding mandrels 18 and 19 and can be pivoted about the point B, so that an assembly position and a transfer position can be assumed.
  • Base plate 14 and workpiece loading device 17 are coordinated so that the grinding process and the workpiece feed and removal can be carried out automatically.
  • the transfer position is indicated by the workpiece 20 shown in broken lines.
  • the grinding unit is sensibly combined with a workpiece loading device in such a way that the existing control elements are optimally used for both functions.
