Definitions

  • the present invention relates to a tool for roughing, smoothing and polishing solid surfaces, particularly adapted for stony materials.
  • the roughing, smoothing and polishing operations a re as known, the last stages of the working of stony materials and substantially serve, in the order, to ha ve a planar surface, to remove the surface roughnesses and, finally, to obtain a specular surface.
  • the most widespread type of tool for these operations consists of a horizontal circular plate provided with rotary and translatory motion, which supports at its lower face a circumferential succession of variou sly arranged abrasive segments or small abrasive discs, called “satellites”, which are rotated about their own axes, in opposite sense with respect to the sense of rotation of the supporting plate.
  • This second model of the above said tool is more ex pensive than the first one, but is shows the advantage of compensating at least partially, through the con trary rotation of the satellites, the difference bet-print the peripheral speeds of points at different distances from the center of rotation of the plate.
  • the abrasive remains in contact with the material being worked only along a generating line of the cylinder and for extremely short times, so that the mud, after having been diluted greatly by the cooling water, is immediately removed as a result of the same rotation of the cylinder.
  • abrasive plate which consists of a normal horizontal plate provided with abrasive elements with horizontal axis, which are radially arranged with respect to the axis of rotation of the plate and have a lower section in the form of a circular arc of about 25°.
  • Said abrasive elements are rotated about their own axes through an angle of 25° in alternated senses, with the result that the contact between the abrasive and the material to be worked occurs continuously along generating lines and the working speed of each single grain of abrasive depends both on its distance from the axis of the plate and on the sense of rotation imparted to the abrasive element in that precise instant.
  • the working speed is thus variable from one to another grain and, for a same abra sive grain, from one to another instant.
  • the object of the present invention is to realize a tool for roughing, smoothing and polishing solid surfa ces, particularly of stony material, which tool, by using partially the favourable features of the above li sted tools, finally results into a reduction of the working times and costs and a quality improvement of the final product.
  • such an object is attai ned by means of a tool, comprising a horizontal plate ro tating about a vertical axis, a plurality of truncated-cone abrasive rollers rotatably supported by said plate in radial position with a lower generating line arranged parallel to the plate plane below said plate, and means for providing each of said rollers with a ro tary motion about their own axes, characterized in that said rotary motion of the rollers has such a sense that, as a result of the combination of the rotary motions of the plate and the rollers and having suitably selected the ratio of the maximum to the minimum diameter of the rollers and the speeds of rotation of the plate and the rollers, all the points of said lower generating line of the rollers have substantially equal speeds of movement with respect to the surface to be worked.
  • the rollers are rotated about their own axes in such a sense as to cause their lower generating line to move in a sense opposite to that of rotation of the plate, i.e. so that along said lower generating line, which is the "working line", the peripheral speed due to the rotation of the plate and that due to the rotation of the roller are substracted from one another.
  • the truncated-cone rollers must have the major base faced to the outside of the plate, so that the maximum value is substracted from the maximum value and the mi nimum value is substracted from the minimum value to make the difference uniform from one to the other end of the roller.
  • the rollers may be rotated about their own axes in such a sense as to cause their lower generating line to move in the same sense of rotation as the plate, i.e. so that along said lower generating li ne the peripheral speed due to the rotation of the pla te and that due to the rotation of the roller are added to one another.
  • the truncated-cone rollers must have the major base faced to the center of the plate, so that the maximum value is added to the minimum value and viceversa.
  • a horizontal plate 1 provided with radial windows 2 is fixed below a rotatable, substantially cup-like, inner support 3, which is rotated about its own vertical axis 19, coincident with that of the plate, as guided by a stationa ry, cup-like, outer support 4, to which the inner support 3 is rotatably connected through bearings 5 and 6.
  • a central rod or sleeve 7 of the rotata ble support 3 there is supplied in conventional manner cooling and washing water, which reaches through radial bores 8 the annular peripheral chamber 9 formed between the lateral lower flaring 10 of the rotatable support 3 and the underlying plate 1.
  • Each roller 11 has end pins 12 and 13 rotatably sup ported by the rotatable support 3 through sealed bearings 14 and 15.
  • the outer pin 12 even exists from the rotatable inner support 3, ending with a pinion 16 in engagement with a crown gear 17 carried by an annular plate 18 ma de integral with the stationary outer support 4.
  • V P1 and V P2 the peripheral speeds of the plate 1 at the diameters D 1 and D 2 , expressed in ms /s ec , V R1 and V R2 the peripheral speeds of the rollers 11 at the diameters d 1 and d , expressed in ms/sec, and V the working speed which is desired to have at every point of the lower generating line of the rollers 11.
  • the tool is made in two separable parts 31 and 32, which are normally fixed to one another by a nut 33 screwed onto the threaded end 34 of a pin 35, which projects downwards from the upper part 31 and passes through a cen tral bore 36 of the lower part 32.
  • the upper part 31 comprises a stationary support 37 and a rotatable support 38, which include respective upwardly extending tubular rods 39 and 40, which are coaxially arrangen and rotatably cou pled to one another through a bearing 41.
  • the rotatable support in turn rotatably carries three shafts 42, which are radially arranged at circumferentially spaced positions and on which a conical pinion 43, engaged with a conical crown gear 44 of the stationary sup port 37, and a cylindrical gear 45 are rigidly mounted.
  • the lower part 32 in turn comprises a support 46, which is rotated along with the rotatable support 38 of the upper part 31 as made integral therewith by the pin 35 and the nut 33.
  • Said support 46 rotatably carries three shafts 47, which are radially arranged at circum ferentially spaced positions, exactly below the shafts 42 of the upper part 31.
  • the shafts 47 are slightly inclined with respect to the horizontal working plane 51, so that each truncated-cone roller 49 has a generating line completely engaged with the same working plane, as it happened to the rollers 11 of the tool of Figs. 1 to 3.
  • a plate 52 fixed to the support 46 completely closes the lower part 32 of the tool, allowing only a minimum section of the rollers 49 around the working generating line to project through the radial windows 53.
  • a feed system for the coo ling and washing water which system extends within the rotatable support 38 of the upper part 31 of the tool in the form of channels 54 and 55 and ends above the rollers 49 into a roller housing chamber 56 (Fig. 4).
  • the shafts 42 are obliged to rotate at higher speed in the sense indicated by the arrow 62 in the same Figure and the rollers 49 are finally obliged to rotate about their own axes in the sense indicated by the arrow 63, i.e. in the sa me sense as the rollers 11 of Fig. 1 upon an identical rotation of the rotatable support 13.
