Definitions

  • An abrasive surface on at least one polishing head is arranged to be brought into contact with the surface and this head is hinged to an arm that is mounted to pivot on a carriage about an axis perpendicular to a plane passing through the axis of a spigot.
  • the carriage is itself mounted to slide on the frame along a plane perpendicular to the axis of a spigot and is reciprocably movable, e.g. by a jack system.
  • FIGS The present invention relates to a machine or polishing surfaces, more particularly of spool flanges.
  • the invention has for an object a machine enabling polishing of surfces to be effected and more particularly of spool flanges of all kinds, whether they are of the flat or straight type, have protuberances, or are double tapered.
  • the machine comprises a frame on which is mounted a shaft rotatable by a drive member, the shaft supporting a surface to be polished and with which is adapted to come into contact an abrasive surface on at least one polishing head hinged to an arm mounted to pivot on a carriage about an axis perpendicular to a plane passing through the axis of the shaft, said carriage being mounted to slide on the frame along a plane perpendicular to the axis of the shaft and being reciprocably moveable.
  • the surface finish obtained depends on a number of factors, primarily the polishing time and more particularly the number of runs of the abrasive tool over the surface to be polished. This machine enables the polishing time and rates of production to be considerably reduced, more particularly where a plurality of polishing heads is used.
  • FIG. 1 shows an elevaton of one embodiment of. a
  • FIG. 2 shows an end view, in partial section, of the machine shown in FIG. 1,
  • FIG. 3 shows a perspective view of an embodiment that includes a plurality of polishing heads
  • FIG. 4 shows an elevation of one method of assembling the polishing head on the arm, I
  • FIG. 5 shows a view, in section, along the line V-V of FIG. 4, and
  • FIG. 6 shows a view in side elevation of the assembly of the polishing head on the arm.
  • FIGS. 1 and 2 show an embodiment of a machine for polishing circular surfaces, which comprises a frame 1 on which is mounted a shaft 2 rotatably driven by a motor and reduction gearing 3 by means of a belt drive 4.
  • the upper part of the shaft 2 is provided with a plate 5 on which rests one of the flanges 6 of a metal spool 7, the surface 6a of which is to be polished.
  • the frame 1 is provided withslideways 8 on which is mounted to slide along a plane perpendicular to the axis of the shaft 2, a carriage 9 which is subjected to the action of a double acting ram 10, the body of which is fixed to the frame 1 and the control rod 10a of which is securely connected at one of its ends to the carriage 9 for reciprocation of the latter along the axis of the arrow A.
  • an arm 12 pivotable about any axis 11 perpendicular to a plane passing through the .axis of the shaft.
  • This arm 12 which has a cranked shape, hingedly carries at its free end, a vibrating polishing head 13.
  • a ram 15 is hinged on the carriage 9 about an axis 14, the rod 16 of the ram being securely connected by one end to a shaft 17 mounted to pivot between the flanges of the arm 12, the said pivot shaft 17 being situated between the pivot shaft 11 and the end of the arm 12 carrying the polishing head.
  • the machine according to the invention operates in the following manner:
  • the spool 7 being placed on the plate 5 of the shaft 2 and the appropriate adjustments of the polishing head 13 with respect to the surface 6a of theflange 6 being effected, the motor and reduction gearing 3 is started up to rotate the shaft 2 and the spool 7.
  • the moving carriage thus effects a series of movements in and against the direction of the arrow A so as to obtain a plurality of runs of the polishing head 13 over the surface 6a during a predetermined time or according to a predetermined number of runs.
  • the polishing head 13 is raised by means of the arm 12 controlled by the ram 15 even though the shaft 2 and the spool 7 are still being rotated. Then the carriage 9 is driven in the reverse direction to arrow A so as to ensure its release from the surface 6a.
  • the embodiment of the machine shown in FIG. 3 comprises a single shaft 2 about which are mounted three carriages 37, 38, 39 on the frame 1, bearing arms 40, 41, 42, on which are hinged polishing heads 13, not shown on the drawing.
  • the latter arrangement enables the polishing time of a spool flange to be considerably reduced by multiplying the number of polishing heads.
  • a polishing machine comprising a frame, a shaft mounted on said frame and rotatable by a drive member, said shaft adapted to support a surface to be polished, a carriage mounted on said frame for reciprocating sliding movement relatively thereto in a plane perpendicular to the axis of said shaft, means for reciprocating said carriage, an arm mounted on said frame for pivotal movement about an axis perpendicular to a plane in which the axis of said shaft lies, at least one polishing head hinged to said arm, for universal movement relatively thereto an abrasive surface on said head, and means for bringing said abrasive surface into contact with the surface to be polished when said carriage is moved towards said surface to be polished.
  • a polishing machine wherein said pivoting arm is connected to said carriage by a ram having a rod hinged to said arm, and also having a body hinged on said sliding carriage, and said sliding carriage being under the control of a ram connected to said frame.
  • a polishing machine wherein a plurality of arms, each bearing a polishing head, is arranged about said shaft.
  • a polishing machine wherein two rods are mounted at the end of said arm to slide vertically against the action of resilient members, said two rods bearing at one of their ends two pivots engaged in two bearings of said one polishing head, said end of said sliding rods also carrying a plate having two ends resting against said one polishing head through resilient members.
