Definitions

  • the purposeof the present invention which has for its object to devise a method and means for perfectly grinding and finishing the grooves or key-ways provided in the-interior of hollow metal I bodies.
  • the grinding elements are oi rhombold shape, and their widest portion is a trifle narrower than the grooves to be finished so that the grinding elements as they are drawn or pushed through helically extending grooves, always bear against the base and one side of the grooves.
  • 1 pivotally support the holders for the grinding elements or pressure rollers so as to enable a pressure-roller holder and Fig. 5 a transverse section through the same.
  • a casing having in its central portion a number of slots 1'.
  • sliding rails shown at 2 which by means of resilient rings 3 and l are held in the casing l.
  • the rails 2 are provided with inclined faces 5 and 6 which bear against cones 1 and 8 provided on an adjustable mandrel 9.
  • the holders At its opposite ends, the holders ill have secured to them a resilient bar shown at i3, which bars each carry a block it. These blocks act as guides for guiding the grinding'stone in the groove to be finished.
  • a guide element mounted on the lower portion of the casing i and held thereon by means of a nut shown at IE.
  • a capnut H which extends over the end of the casing that is formed with screw-threads to receive the nut.
  • the not I! is prevented from'rotation by a clamping member it which by means of a wedge i9 and a pressure screw is pressed against the female threads of nut ii.
  • a screw shown at 20 against a slanting face 22 provided on the wedge 19 the latter is moved towards the right in Fig. 1, thus forcing with its wedge-face ii the clamping memher it outwardly.
  • a pressure ball-bearing shown at 26 and Ti respectively permitting a rotation of the casing i relative to the shank it of the chuck.
  • a spindle 29 which by means of a divided collarnut shown at it is connected with the adjustable mandrel 9 holding the latter in its adjusted position.
  • a ball shown at i i Intermediate the mandrel 9 and the spindle it is provided a ball shown at i i, facilitating rotation of the parts relative to each other.
  • the casing i. is connected with a drawing spindle (not shown) whereby the device, after the guide blocks II have first been introduced into the grooves to be finished, is repeatedly drawn or pushed back and forth through the hollow metal body.
  • the positioning of the grinding stones ll may be easily accomplished as follows;
  • the screw 20 is loosened, whereby the tension between the wedge l9 and the clamping member l8, on the one hand, and between the latter and the cap-nut H, on the other hand, is sufiiciently relaxed to enable the cap-nut to be screwed along the screw threads of casin: I, whereby the cap-nut becomes displaced, resulting in a corresponding displacement of the hollow shank 2!, of the spindle 29 secured therein and of the adjustable mandrel 9.
  • its conical portions 1 and 8 wii cause the sliding rails 2 carrying the grinding stones H to move inwards or outwards in the slots of the casing.
  • the grinding stones l I held by the holders l0 pivotally carried by the rails 2 can be posi tioned to any desired outer diameter.
  • a device of the kind described in combination a casing, a plurality of tools of rhomboid shape movably mounted at the periphery of said casing, the greatest width of said tools in their center being smaller than the width of the grooves to be finished, and guiding means for said tools.
  • a casing provided with slots, sliding rails mounted in said slots, holders pivotally carried by said sliding rails, tools secured to said holders, resilient guiding means on said holders for said tools, a mandrel in said casing axially movable therein in cooperative relation to said sliding rails for positioning them circumferentially relative to said casing, and means for axially displacing said mandrel.
  • a casing provided with slots, sliding rails mounted in said slots, holders pivotally carried by said sliding rails, tools secured to said holders, resilient guiding means on said holders for said tools, a mandrel axially movable in said casing and having conical portions bearing against corresponding faces on said rails for circumierentially displacing said rails in said slots relative to said casing, and means for axially displacing said mandrel.
  • a hollow shank adapted to be operatively connected with a chuck, a spindle secured within said hollow shank, a casing connected with said shank and provided with slots, sliding rails mounted in said slots, holders pivotally carried by said rails, tools secured to said holders, resilient guiding means on said holders for said tools, a mandrel axially movable in said casing in cooperative relationship to said sliding rails for eircumferentially displacing the same relative to said casing, and means operatively connecting said mandrel with said spindle, said connecting means including a ball permitting a relative rotary movement between said mandrel and said spindle.
  • sliding rails mounted in said slots, holders pivotally carried by said rails, tools secured to said holders, guiding means on said holders for said tools, a mandrel axially movable in said casing in cooperative relationship to said sliding rails for circumierentially displacing the same rela tive to said casing, means operatively connecting said mandrel with said spindle, and means connecting said casing with said shank, said means including ball-bearings so as to permit a relative twist between said casing and said shank.
  • a hollow shank adapted to be operatively connected with a chuck, a spindle secured within said hollow shank, a casing provided with slots, sliding rails mounted in said slots, holders pivotally carried by said rails, tools secured to said holders, guiding means on said holders for said tools, a mandrel axially movable in said casing in cooperative relationship to said sliding rails for circumferentially displacing the same relative to said casing, means operatively connecting said mandrel with said spindle, a cap-nut engaging a flange on said'shank and screw-threads on said casing thereby connecting these parts, and ball-bearings in said connection so as to permit a relative twist between these parts.
