Definitions

  • a polishing machine which has an oscillatable frame supporting at least one hollow drum adapted for receiving the workpieces to be treated, each drum being rotatably supported from a pair of discs which in turn are supported from the frame for rotation about an axis which is perpendicular to the axis of rotation of the frame and is in the same plane therewith.
  • the drum undergoes movement influenced by three independent rotations which are respectively controllable.
  • An object of the present invention is to avoid the disadvantages and defects of the known tumbling and polishing machines and to provide a machine which is improved as regards efficiency, the time required for the treatment of the workpieces and the simplicity and economic working procedure as regards the use and operating of the machine.
  • Two drums in axially parallel relation may be mounted on the rotor discs or plates on opposite sides of the axis of rotation of the discs or plates.
  • the drums may be cylindrical and may be equispaced from the axis of rotation of the rotor discs and diametrically opposite from one another with respect to'said axis of rotation.
  • Each drum is provided with a cover with a quick-closure device and in addition with a union for connection with a liquid conduit, through which flushing liquid or treatment liquid can be introduced into the interior of each drum.
  • the introduction of this liquid can be effected through a hollow shaft supporting the discs and connected to the drum.
  • the discharge of the liquid is effected by way of outlet openings in a closable liquid outlet in the cover, in which a sieve is arranged.
  • the machine according to the invention is preferably constructed so that the ratio between the diameter of the drum and the diameter of the circular path which is described by the axis of the drum during its movement amounts to approximately l:2.3.
  • the machine is also constructed so that the speed of rotation of each drum is twice as fast as that of the rotor discs carrying it.
  • FIG. 1 is a perspective view of a tumbling and polishing machine with two drums, according to the invention, in simplified form with the drive means omitted;
  • FIG. 2 is an elevational cross section through the machine with only one drum being shown;
  • FIG. 3 is a side elevation view of the machine in the filling position
  • FIG. 4 is a side elevation corresponding to FIG. 3, with the drums in the emptying position;
  • FIG. 5 is a front elevational view, partly broken away and in section, of a machine similar to that in FIG. 1 but with four drums and the drive means illustrated;
  • FIG. 6 is a plan view, partly in section, of the machine of FIG. 5;

  • FIG. 1 The basic structure of the tumbling and polishing machine will be seen from FIG. 1.
  • This machine comprises a support 11 with two bearings 12, in which are mounted shafts 13 of a frame 14, which is mounted so as to be pivotable about a horizontal axis X-X.
  • Mounted in this frame 14 is a shaft l5, rotatable about axis Y-Y which is disposed in the same plane as axis X-X and perpendicular thereto. Consequently, there is provided a gimbal suspension for two tumbling and polishing drums 18 mounted on rotor discs 16 and 17.
  • the rotor disc 16 is secured on shaft and carries two bearings 19 (one of which is shown in FIG. 2).
  • each bearing 19 there is rotatably mounted a drum shaft 20 secured to base wall 180 of a respective drum 18.
  • a driving force for rotating the drums is operative on shafts 20.
  • the drums 18 are supported by means of the engagement of drum wall 18b in a roller bearing 21 in an aperture in the rotor plate 17, the drum wall 18b projecting outwardly somewhat beyond the plate 17.
  • each drum 18 is adapted to be closed by a cover 22, which is provided with a closure device which is quickly released and secured so that the cover can be both quickly and easily released and removed and subsequently fitted and secured in place.
  • Attached to the cover is a connecting union 23 for the connection of a liquid supply 24.
  • the radius of each of the drums 18 is half as large as the spacing between the drum axes Z and the axis Y of the rotor discs or plates 16,17; furthermore, the machine and its drive means are so constructed that the speed of rotation of the drums 18 is twice as fast as that of the rotor plates 16,17.
  • the driving of the moving parts of the machine according to the invention is advantageously effected by separate driving motors, which may be hydraulic or electrical.
  • two motors 25,26 respectively drive the rotor shaft 15, and the drums 18 independently of one another.
  • the motors 25,26 are mounted on a suspension 14a of the pivotable frame 14.
  • the motors 25,26 are connected via cables 27 to a supply source. Thus, if motors 25,26
  • the cables 27 are electrical, the cables 27 are connected to an electrical voltage source for driving the motors.
  • the cables 27 are flexible to follow the swiveling motion of the frame about the axis X-X which is in the range of about If the motors are hydraulic, the cables 27 are in the form of tubing for the supply of pressure fluid to operate the motors.
  • the motor 25 driving the shaft 15 is drivingly coupled by a transmission belt 28 to a ring 29 mounted on the disc 16 and serving as a belt pulley.
  • the motor 26 driving drums 18 is drivingly coupled by means of a transmission belt 30 to a belt pulley 31 loosely positioned on the shaft 15.
  • Hub 31a is designed to act as a belt pulley and is coupled to a toothed belt 32 which passes around belt pulleys arranged on the shafts 20 of drums 18 within the ring 29. This construction allows an infinitely variable control of the rotational speed of drums 18 independent of the rotational speed of rotor shaft 15, or rotor discs 16,17 respectively.
  • FIG. '7 shows a slightly modified construction for the drive of drums 18 wherein each of the shafts 20 of the drums 18 is driven from a respective driving motor 34, preferably a hydraulic motor.
  • a respective driving motor 34 preferably a hydraulic motor.
  • the driving of the rotor shaft 15 is effected by means of a driving motor on the frame 14 in turn driving the ring 29, mounted on the rotor disc 16 and surrounding the hydraulic motors 34 by means of the belt 28.
  • the supply of the pressure fluid to the hydraulic motors 34, and the drainage therefrom is effected, respectively, by means of flexible tubings 27 through a sleeve 35 provided with two separate ducts 36,37 connected to annular grooves 38,39, said sleeve being loosely positioned on the rotor disc shaft 15 so as to be nonrotatable.
  • Sleeve 35 is surrounded by a rigid rotating housing 40 connected to the disc 16.
  • Tubings 41,42 are connected on the one hand to the hydraulic motors 34 and on the other hand to the housing 49 so as to terminate in the annular grooves 38,39 in the housing 40 and supply the motors 34 with pressure fluid.
  • a hydraulic cylinder 43 is arranged between the frame 114 and the support 11 for the purpose of pivoting the frame 14 about the axis X-X to rock the drums 18.
  • the pivoting movement of the frame 14 about the axis X-X is preferably made 5 to 10 times per minute during the tumbling or polishing action, which results in a particularly favorable mixing of the workpieces contained in the drums 18 with the abrading or polishing agents.
  • the pivoting movement of the frame 14, and the drums 18 therewith, during the rinsing operation has the effect that the workpieces are particularly thoroughly cleaned.
  • the filling and emptying of the drums 18 is promoted by the tilting of the frame 14 about axis X-X and respectively holding the same in positions in which the drum openings are directed upwardly and downwardly.
  • the drums 18 may be emptied automatically under the action of gravity.
  • a flushing liquid is supplied to the drums 18 through a tube 44 connected by means of a coupling 45 to the hollow rotor shaft 15 so that said shaft 15 is rotatable with respect to the tube.
  • a distributor ring 46 connected to the supply tubes 23 which are fastened to the covers 22 for conveying the flushing liquid to drums 18.
  • the connection of the supply tubes 23 with the covers 22 of the drums 18 is also designed to be a revolving turret so that drums 18 may rotate with respect to tubes 23.
