Definitions

  • the innovation relates to a device for grinding and lapping ring-shaped sealing surfaces in valves, slides and the like, with a mount which can be fastened to the workpiece and which has a drive on the one hand and a rotatably mounted tool plate on the other, which is coupled to the drive via a transmission element and a row by freely rotatably mounted grinding or lapping heads, the axes of which run parallel to the axis of rotation of the tool plate and, on the other hand, are adjustable in the radial direction.
  • Devices of this type are used in particular to grind and lap sealing surfaces in valves, slides, valve disks, slide wedges, slide plates and flanges in their installed position.
  • the diameter of the individual grinding or lapping heads is selected such that it is larger than the radial width of the ring surface to be treated. This can lead to the need to replace the tool heads in order to be able to adapt them to the surface to be treated.
  • the object of the present invention is now to design a device of the type mentioned at the outset so that, with simple adjustment, it enables tool heads to be used for machining annular sealing surfaces, the radial width of which is greater than the diameter of the tool heads.
  • the tool plate has a bearing bore offset from its center, in which a circular bearing disc is adjustably mounted, with which a drive pin coupled to the transmission element is connected in a rotationally fixed connection outside of its center.
  • the pivot point of the plate is changed by adjusting the bearing disc in relation to the bearing bore of the tool plate.
  • the distance between the individual tool axes and the axis of rotation is varied. It can then be achieved that the individual tool heads run on circular paths whose diameters are not the same as one another. In this way, the tool heads can cover an annular sealing surface, the radial width of which is greater than the diameter of the tool heads.
  • the device according to the innovation can also be designed so that the eccentricity of the bearing bore with respect to the center of the tool plate is equal to the eccentricity of the point of engagement of the drive pin on the bearing washer with respect to this washer. This arrangement makes it possible to arrange the point of engagement of the drive pin centrally to the tool plate for adjustment purposes.
  • the device according to the innovation can also be designed so that the bearing bore forms a shoulder on which a counter shoulder of the bearing disc rests.
  • the device according to the innovation can be designed so that the bearing disc is screwed to the tool plate.
  • threaded bores and corresponding push-through bores are provided in the bearing plate or in the tool plate. It is then possible to move the bearing washer according to the pitch of the screw connection in relation to the tool plate. The eccentricity of the drive of the tool plate can thus be changed in corresponding jumps.
  • the device according to the innovation has a holder 1 with which it can be fixed in a manner not described here in detail on a workpiece which has an annular sealing surface 25 to be ground or lapped.
  • the holder 1 carries a drive 2 and has tubes 3 which connect the drive 2 to a tool plate 4.
  • a transmission element (not shown) runs in the tubes 3 and transmits a rotary movement of the drive 2 to a drive pin 5.
  • This drive pin 5 is mounted in a lower end piece 6 of the holder 1.
  • the drive pin 5 is spherical at its end 7 protruding from the end piece 6 and equipped with two diametrically and transversely to the axis of the drive pin 5 pins 8, which serve to transmit the rotary movement of the drive 2 and thus the drive pin 5.
  • the spherical end 7 of the drive pin 5 engages in a corresponding spherical cap 9 of a bearing disk 10.
  • the pins 8 come to lie in corresponding recesses in the spherical cap 9.
  • the bearing disc 10 has a section 11, which is followed by a section 12 with a larger diameter.
  • the section 11 thus forms a radially projecting flange 13 and a shoulder in which threaded bores 26 are provided.
  • the bearing plate 10 is circular, the axis of the spherical cap 9 being offset by a dimension a from the central axis 14 of the bearing plate 10.
  • the bearing disk 10 is received by a correspondingly designed bearing bore 15 in the hub area of the essentially rotationally symmetrical tool plate 4.
  • the axis 15a of the bearing bore 15 is offset by the dimension a with respect to the central axis 14 of the tool plate 4.
  • the bearing disk 10 can be rotated in the bearing bore 15.
  • the bearing disc 10 can be fixed in a number of positions relative to the tool plate 4 by the screws 18.
  • the section 11 of the bearing disk 10 is provided with markings 19 which cooperate with an opposite marking on the tool plate 4. These markings indicate when the bearing disc 10 is arranged in relation to the tool plate 4 such that the axis of the drive pin 5 coincides with the central axis of the tool plate 4, that is to say the eccentricity is “0”. The markings also enable the respective eccentricity of the drive axis to the axis of the tool plate 4 to be set.
  • the tool plate 4 is provided with radial grooves 20 for receiving freely rotatable lapping or grinding heads 21.
  • the bearing disc 10 is first set to the eccentricity "0". In this setting, the tool plate 4 is aligned in position with the annular sealing surface 25 to be treated. The desired eccentricity is then set by rotating the bearing disc 10 in the bearing bore 15 so that the individual lapping or grinding heads 21 are at different distances from one another from the pivot point of the tool plate 4.
