Definitions

  • This invention relates to devices for truing the internal walls of cylinders by a rotary grinding or abrading action, and is particularly intended for use bot-h in connection with new engine cylinders to give them a perfect initial bore and also in connection with used engine cylinders to eliminate tapers and ovals therein resulting from use.
  • a rlhe object of this invention is the provision of a device -ofthe character described,
  • the invention- is to provide a device of this character which is capable of having its abrading members set at any desired adjustment-and tounyieldingly maintain such adjustment, and also of hav-v ing such members set for a ypredetermined limit of inward of collapsing movements and to have a yielding outward abrading pressure applied thereto, depending' on the nature and particular requirements of the work to be performed.

  • l ⁇ igure 1 is a side elevation ⁇ of a tool embodying the invention with the s ring tension relieved and witha part breien away.
  • Fig. 2 is a central longitudinal section of the 'of the bosses, these arms being 'the tool body, which has-a central bore or opening 2 longitudinally therethrough and is provided in eq'uidistantly spaced relation around its outer side with longitudinally apertured bearing bosses 3 extending lengthwise of the body with their aperturesparallel to the body axis.
  • the body l is substantially rectangular inr cross-section and has at each corner an extension forming a bearing boss 3.
  • Each boss 3 has a.
  • the body 1 is provided at its inner end with a thrust head 8, which is centrally apertured in axial alignment with the aperture 2 through the body, and, in the presentinstance, is secured to the body by the pivot pins 4, which thread therein.
  • ' 'Ehe pins t are also preferably tixed in the bearing bosses ot the body by pins 9 (Fig. 1), or din any other suitable manner, and the thrust head 8 is spaced from the inner end ot the body i l a distanceequal to the width oit the ren spective hinge arms of the carriers 5.
  • shaft 10 is feathered in the bore 2 et' the body l to permit it to have axial movements relative thereto and to ycause the hedy to rotate therewith.
  • the removable cone in the present instance, is threaded on the lower extended end portion of the shaft and is locked in shouldered end thereof, is provided with a tapered boss or projectionv 13 which opposes and is complemental to the tapered surface of the adjacent cone 11,.so that the inward swinging movements o the carriers relative to the body are stopped by the cones, and axial movements of the shaft and its cones will permit either a further inward movement of the carriers or will cause positive uniform outward movements thereof, depending on the direction 'of movement of the cones.
  • the shaft 10 extends outwardly through the central aperture inthe thrust head 8 and is provided at its outer end in suitable spaced relation to the thrust head with means for attaching it to a motor shaft, drill press spindle or other suitable driving means.
  • he attaching means in the present instance, is shown as comprising a socket member 15.

  • the stop sleeve 17. is turned down with/ its lower end in engagement with the thrust head,8, it will be apparent that the shaft 10 will be drawn upward relative to the body 1, thereby causing the cones 11 to be set in any desired position of adjustment with respect to the engaging portions 13 of the carriers 5.
  • a set screw 19 may diameter than that for which ,the stones are set inasmuch as there is no provision iny this casev for exerting a yielding outward pressure on the carriers to continue the grinding action beyond the-point for which thecones are set.

  • an adjusting nut 20 is threaded on the stop sleeve 17 and a coiled compression spring 21 is interposed between it and the thrust head 8. It is evident that by turning the stop sleeve 17 back from engagement with the thrust head 18, and turning the nut 2() ldown to tension the spring 21, a yielding pull is exerted on the shaft l() relative to the holder 1 to cause the cones 11 to exert a yielding outward pressure on the hone carriers from a contracted position permitted by the spring 21.
  • a tubular member 25 is substituted for the thrust head 8 and has its bore of adequate size to receive the compression spring 26 between it and the cone carryin shaft, designated 27.
  • An externally t readed sleeve '28 is threaded into the outer end of the member25 and bears against the outer end of the spring 26, while the Iinner end thrust of such s ring is exerted against the inner cone 29 o the shaft. It is apparent that an adjustmenty of the spring tension is eected by an inward or outward turning of the sleeve 28. ln this form the direction of taper of the cones is reversed over that previously described.
  • the holder is provided at its inner end with a tubular extension sleeve 30 into which is threaded the stop sleeve 3l, the lower end of which may be turned into stop engagement with Y the upper large endof the ad'ustment cone 32.
