Definitions

  • My invention removes the above drawbacks, not only by providing for the efficient cooling of the bearings of the spindle and for the watering of the grinding wheel and of the work undergoing the grinding operation, but also by doing away entirely with any complicated machining or mounting for achieving the essential objects set forth.
  • My invention resides in a device for watering and cooling spindles for inner grinding operations which arrangement is characterized by the fact that between the admission of the cooling and watering liquid to the machine frame on one hand and the grinding wheel and the grinding zone on the other hand, said liquid instead of 2 Claims. Cl. 51--267) being guided in channels as in the prior arrangements flows freely over and along the spindle carrier or the like device holding or containing the spindle and its associated parts.
  • the liquid fed under pressure to an intermediary collector or water container in the frame passes out of same through an annular nozzle surrounding the rear end of the spindle carrier, after which it flows over the latter up to the grinding wheel while forming round the spindle carrier a cooling hydraulic sheath which is permanently renewed and the speed output of which may be adjusted by modifying the pressure at which the liquid is fed.
  • my invention has the advantage of allowing the grinding of inner chambers with a grinding spindle carrier the diameter of which is smaller than that of the spindles carriers used heretofore, which allows grinding parts which could not be ground with any previously known machine.
  • a connection 5 screwed transversally into the frame 2 is connected with a supply of water under pressure which has not been illustrated so as to feed a ring-shaped chamber 6 surrounding the base 1 of the spindle carrier I, while its front part ends under the form of a circular edge 8 forming an outlet nozzle of reduced width surrounding the body of the spindle carrier.
  • the liquid forced out of the ring-shaped chamber through said nozzle streams over said body of the spindle carrier and forms round it a moving cooling sheet 9 leading to the grinding wheel 3 which is also cooled thereby after which it waters in a continuous manner at H! the wall of the bore 4 during the grinding operation.
  • Fig. 2 relate to bores of a considerable length which is such that the flow of water may not reach the grinding wheel and the work being ground.
  • the water chamber designated in Fig. 2 by the reference number 22 is then provided separate from the frame and is formed inside a cooling block l2 rigid with the member to be ground l3 inasmuch as it moves only, in unison with the latter, with a longitudinal reciprocatory movement with reference to the system including the spindle carrier I and the grinding wheel 3.
  • An annular packing Id of leather or the like material, plays the part of a stuffing box and provides for the water-tightness of the rear part of the container or chamber I! while allowing its longitudinal movement over the spindle carrier; at the same time the front end of the container is bounded by a second packing l5 bearing against a Washer l6 held in place b an elastic ring ll.
  • This packing I5 is provided with a collar I8 form- M ing a nozzle forcing out of the chamber the water fed thereto under pressure through the connection 19.
  • a stay or intermediate member 20 provided with peripheral holes is arranged between the two packings l4 and I5.
  • My invention is not only applicable to inner grinding but may be used also for the cooling of tools executing other mechanical operations.
  • a rotatable shaft a grinding wheel secured to said rotatable shaft at one end thereof; a non-rotatable container surrounding a portion of said shaft; a fluid conduit connected with said non-rotatable container for admitting cooling fluid under pressure into the same; an opening arranged at that end of said container which is nearer to said grinding wheel and being slightly larger than said shaft passing therethrough so as to form a substantially annular slot around said shaft adjacent to the surface thereof; and closing means forming part of said non-rotatable container and arranged between the same and said rotatable shaft at the other end of said non-rotatable container.
  • a rotatable shaft In combination in a high speed grinding machine, a rotatable shaft; a grinding Wheel secured to said rotatable shaft at the front end thereof; a non-rotatable fluid container surrounding a portion of said shaft; an opening at the front end of said non-rotatable container being slightly larger than the cross section of said shaft so as to enable ejection of cooling fluid from said container along the surface of said shaft towards said grinding wheel; and closing means at the rear end of said non-rotatable container arranged between the same and said rotatable shaft.
