[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a planetary rotary barrel machine for improving workability.

[0002]

2. Description of the Related Art Heretofore, there has been known a planetary revolving type barrel processing machine having a rectangular (all rectangular parallelepiped) barrel tank having a cross section perpendicular to the rotation axis (Japanese Patent Application Laid-Open No. 56-146661).
issue).

[0003]

Problems to be solved by the invention Conventional planetary revolving barrel processing machines that have been conventionally used have been large in size due to the large turning radius of the barrel tank. Therefore, an attempt was made to reduce the turning radius, but when the turning radius was reduced, the interval between the barrel tanks was inevitably reduced, and the space in which the barrel lid could be opened and closed was reduced, making it difficult to take out the contents. However, there is a problem that workability is deteriorated.

[0004]

According to the present invention, however, the mounting angle of the adjacent barrel tank (or barrel case, hereinafter the same) is set to 9 degrees.
By offsetting by 0 degrees, the distance between the adjacent barrel tanks was relatively widened, and the above-mentioned conventional problem was solved.

[0005] That is, the present invention is a revolving turret,
In a barrel processing machine in which rotating barrel tubs are mounted at equal intervals, the barrel tub or barrel case has a rectangular cross section perpendicular to the rotation axis, and the adjacent barrel tub or barrel case has a 90 ° rotation about the rotation axis. A planetary turning type barrel processing machine characterized by being installed in a different direction. The workpiece is fixed in a barrel tank or a barrel case via a jig. Next, the workpiece fixed in the barrel case has a hollow cylindrical shape so that an abrasive can be sealed therein.

[0006]

According to this invention, since the mounting angle of the adjacent rectangular parallelepiped barrel tanks is shifted by 90 degrees, the space in which the barrel lid can be opened and closed is enlarged, and the contents can be taken out and other workability is improved. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An airframe 1 is a box made of an iron plate, and a main shaft 2 is laid laterally by bearings 3 and 3 at a central portion thereof.
A turret driving wheel 4 and a disc-shaped turret 5 are fixed to the main shaft 2 at a predetermined interval, and a planetary wheel driving wheel 6 is rotatably fitted. The turret driving wheel 4 has a shape in which a short cylinder with a crest is laid horizontally, and a central portion of a top plate 4a is a main shaft 2
Are fixed at right angles to each other, and several bearings 7 are installed at equal intervals on a concentric circumference centered on the fixing portion, and a bearing 7a is installed on the concentric circumference of the turret 5 corresponding to the bearing 7;
The shafts 9, 9a of the barrel case 8 are rotatably mounted on the bearings 7, 7a, and the driving wheel 10 is fixed to the shaft 9. The planetary wheel drive wheel 6 has a barrel case 8
The same number of case driving wheels 11 and the number of interlocking wheels 12 for rotating the planetary wheel driving wheels 6 are fixed. A case lid 8 a is hinged to the barrel case 8. The number of barrel cases 8 erected on the turret 5 may be an even number of 4 or more, but usually 4
The pieces are symmetrically installed. The workpiece 13 (cylinder) shown in FIG. 6 is set in the barrel case 8 via the rack 17 as shown in FIGS.

In this embodiment, two rows of hollow cylindrical workpieces 13 (such as high-pressure gas cylinders) are installed in a barrel case 8,
The abrasive slides on the inner surfaces 13a and 13b of the workpiece 13 to polish it. Four barrel cases 8, 8 are installed on the turret 5 at 90 ° intervals, and the driving wheel 10 of the shafts 9, 9a and the planetary wheel driving wheel 6 of the main shaft 2 are connected by a chain or a timing belt or a gear. (V-belt is not possible because it causes slippage). The barrel case 8 is set so that the neighbors change the direction by 90 °. That is, in FIGS. 1 and 2, if the front barrel case 8 is horizontal, the upper barrel case 8 is vertical, the rear barrel case 8 is horizontal, and the lower barrel case 8 is vertical. The ratio n / N between the number of revolutions N and the number of revolutions n is set to -1.

In the state described above, the barrel case 8,
When 8 is turned, the adjacent barrel cases 8 and 8
The workpiece 13 is turned while the orientation is different, and the inner surface of the workpiece 13 is polished. After the completion of the polishing, the barrel case 8 is positioned at the workpiece removal position. At this time, the barrel case 8 in a horizontal state as shown in FIG. 1 is first positioned. afterwards,
The work piece 13 is taken out by opening the barrel cover 8a, the next work piece 13 is set, and the barrel cover 8a is closed. Next, when the turret 5 is turned by 90 °, the barrel case 8 in the vertical state is positioned, so that the rotation motor 15 is driven to rotate the barrel shaft 9 by 90 ° and stop. Thereafter, the same operation as described above is repeated.

In FIG. 2, reference numeral 14 denotes a revolution motor, and 16 denotes a speed reducer. In the above description, the ratio n / N between the number of revolutions N and the number of revolutions n is generally set to −1, but it may be better to change n / N depending on the workpiece.

[0011]

[Effects of the Invention] This invention has the effect of preventing the deterioration of workability even if the turning radius is reduced, because the rectangular parallelepiped barrel tank or the adjacent barrel case is installed with a 90 ° turning direction. There is. Therefore, as compared with a conventional processing machine of this kind having the same capacity, there is an effect that the whole can be significantly reduced in size and workability can be improved.
