Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in vibratory barrel polishing equipment.

In the conventional donut-shaped vibrating barrel polishing device, as shown in FIG. Then, it is forcibly raised from the arc-shaped bottom wall la toward the outer circumferential wall lb in the direction of arrow a.

Then, the mass that has completely risen flows toward the inner circumferential wall lc of the barrel tank 1 as shown in the figure b, and turns while flowing again toward the arcuate bottom wall la of the barrel tank. Such a turning movement of the mass in the barrel tank rotates the upper weight 3a and bottom weight 3b attached to both ends of the motor 2, and rotates the barrel tank I mounted on the springs 5, 5, etc. on the frame 4. It is given by making strong movements.

Therefore, the strong oscillating flow applied to the barrel tank 1 is transmitted to the mass in the barrel tank, which is forced to rotate to generate a mutual flow having a mutual contact pressure between the abrasive material in the mass and the workpiece, thereby polishing the workpiece. and each weight 3a attached to the shaft of the motor 2. When 3b is maintained at an arbitrary advance angle, it rotates in a spiral as shown by the solid line arrow in Figure 2, and rotates and flows in the direction of arrow c in the barrel tank for polishing.
If the workpiece is relatively light, the outer peripheral wall of the barrel tank l
When the pressurized object, which is forcibly raised in the direction b as shown by the arrow a, flows toward the inner circumferential wall lc and flows again into the arcuate bottom wall la of the barrel tank 1, the workpiece is polished. Sometimes it floats above the wood and does not sink into the sanding hole. Therefore, there was a drawback that polishing was not performed and the polishing efficiency was reduced. The present invention eliminates such conventional drawbacks, and one embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 3 is a partially cutaway front view showing one embodiment of the polishing apparatus of the present invention, FIG. 2 is a plan view of the same, and FIGS.
The same reference numerals are given to the same parts as in the figures.

In the figure, ld is a pressurized flow wall provided on the outer peripheral wall of the barrel tank 1 and extends inward in a substantially horizontal direction, d indicates the pressurizing direction of the polishing flow, and e indicates the polishing flow caused by the pressurization. It indicates the direction of flow. Due to the forced motion, a flow acts in the direction of arrow a from the arc-shaped bottom wall la in the chamber and rises in the direction of lb, but at this time, the configuration of the pressurized flow wall of lb causes the polishing flow to be applied in the direction of arrow d. This pressurizing action generates a strong frictional flow, resulting in strong grinding and polishing. e indicates the flow and direction; unlike the flow in the conventional method shown in Fig. 1, as shown in Fig. 3 of the present invention, the flow swells to a high position on the upper surface of the tank and then swirls to the high position of lc. Of course, polishing can be done with effective and efficient pressurization.
Strong grinding, which was previously impossible, is now possible. Reference numeral 6 denotes a cylinder '0 rotatably provided along the inner circumferential wall lc of a conventional barrel polishing device, and an appropriate number of rectangular blades 7 are provided on the face of this cylinder 06.
Attach the cylinder D so that it is tilted downward with respect to the central axis of the cylinder D.

The direction of inclination is the rotational flow direction of the mass (arrow c in Figure 2). Although not shown in the figure, the cylindrical core 6 may be rotated by a motor provided in the center space of the barrel tank 1, or may be rotated by another method. In such a configuration, if the mass is rotating and flowing in the direction of disappearance c in the barrel tank 1 while spirally turning as shown in the solid line arrow as shown in Fig. 4, it will flow in the opposite direction or as necessary Accordingly, the cylinder D6 is rotated in the same direction.

Then, pressure acts on the abrasive material and the pressurized object in the direction of being pushed downward by the inclined surface of the blades 7 of the cylinder core 6.
The floated object to be pressurized sinks into the abrasive material again by the blades 7, and is forcibly raised from the arc-shaped bottom wall la toward the outer peripheral wall lb, thereby performing polishing. Note that it goes without saying that the shape and inclination angle of the blade 7 can be freely selected depending on the purpose. Further, there is no particular need to rotate the cylinder core 6, and since the mass moves along the forehead slope of the blade 7 even in a stopped state, it is natural for the pressurized object to sneak into the mass. As explained above, according to the device of the present invention, by adding forced downward movement on the inner circumferential wall to the spiral swirling flow caused by the vibrating barrel, the frictional flow between the pressurized object and the abrasive material is increased. The polishing efficiency is extremely high, and the effect is particularly great when the object to be pressurized is particularly lightweight.
