[Arrangement] In a barrel processing machine in which a rotating barrel tank or barrel case is attached to a revolving turret at equal intervals, the barrel tank or barrel case has a rectangular cross section perpendicular to the axis of rotation, and an adjacent barrel tank or The barrel case is a planetary swivel type barrel processing machine installed with its direction turned 90 degrees around the rotation axis. The work piece is fixed in a barrel tank or a barrel case via a jig. When the workpiece has a hollow cylindrical shape, an abrasive can be enclosed inside.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a planetary swivel type barrel processing machine for improving workability.

[0002]

[Prior Art]

 Heretofore, a planetary turning type barrel processing machine having a barrel tank whose cross section perpendicular to the rotation axis is rectangular (the shape of a rectangular parallelepiped as a whole) has been known (Japanese Patent Laid-Open No. 56-146661).

[0003]

[Problems to be solved by devising]

 Conventionally, the planetary swivel type barrel processing machine that was normally used had a large size due to the large turning radius of the barrel tank. Therefore, attempts were made to reduce the turning radius.However, if the turning radius is reduced, the space between the barrel tanks will inevitably become narrower, and the space for opening and closing the barrel lid will become smaller, making it difficult to take out the contents. However, there was a problem that the workability deteriorated.

[0004]

[Means for solving the problem]

 However, the present invention solves the above-mentioned conventional problems by shifting the mounting angle of the adjacent barrel tanks (or barrel case, the same applies hereinafter) by 90 degrees to relatively widen the intervals between the adjacent barrel tanks.

That is, the present invention relates to a barrel processing machine in which rotating barrel barrel tanks are attached to a revolving turret at equal intervals, and the barrel tank or barrel case has a rectangular cross section perpendicular to the rotation axis, The barrel tank or barrel case is a planetary swivel type barrel processing machine, which is installed by turning 90 degrees around the rotation axis. Moreover, the workpiece is fixed in the barrel tank or the barrel case via a jig. Next, the workpiece fixed in the barrel case has a hollow cylindrical shape, and an abrasive can be enclosed inside.

[0006]

[Action]

 According to this invention, since the adjacent rectangular barrel-shaped barrel tanks are mounted with the mounting angles thereof shifted by 90 degrees, the space for opening and closing the barrel lid is increased, and the workability of taking out contents and other workability is improved.

[0007]

【Example】

 The machine body 1 is a box made of an iron plate, and a main shaft 2 is laterally installed by bearings 3 and 3 in a central portion thereof. A turret drive wheel 4 and a disc-shaped turret 5 are fixed to the main shaft 2 with a predetermined space therebetween, and a planet wheel drive wheel 6 is rotatably fitted therein. The turret driving wheel 4 has a shape of a short cylinder having a top, and the top plate 4a is fixed to the main shaft 2 at a right angle to the center of the top plate 4a. Several bearings 7 are installed at equal intervals, and a bearing 7a is installed on the concentric circumference of the turret 5 corresponding to the bearing 7, and the shafts 9 and 9a of the barrel case 8 are installed on the bearings 7 and 7a. A drive wheel 10 is fixed to the shaft 9 so as to be rotatably installed. The planet wheel drive wheels 6 are fixed with the same number of case drive wheels 11 as the number of barrel cases 8 and an interlocking wheel 12 for rotating the planet wheel drive wheels 6. A case lid 8a is hinged to the barrel case 8. The number of barrel cases 8 to be erected on the turret 5 may be an even number of 4 or more, but normally four halves are symmetrically erected. The work piece 13 (bulb) shown in FIG. 6 is set in the barrel case 8 via the rack 17 as shown in FIGS.

In this embodiment, two hollow cylindrical workpieces 13 (high-pressure gas cylinders, etc.) are installed in the barrel case 8, and the inner surfaces 13a and 13b of the workpieces 13 are polished by sliding abrasives. It is a thing. The four barrel cases 8 and 8 are installed on the turret 5 at 90 ° intervals, and the drive wheel 10 of the shafts 9 and 9a and the planet wheel drive wheel 6 of the main shaft 2 are connected by a chain, a timing belt or a gear. (Because V-belts cause slippage, it is not possible). The barrel case 8 is installed with its neighbors turned 90 degrees. That is, in FIGS. 1 and 2, if the front barrel case 8 is horizontal, the upper barrel case 8 is vertical, the inner barrel case 8 is horizontal, and the lower barrel case 8 is vertical. Further, the ratio n / N of the revolution number N and the revolution number n is set to -1.

When the barrel cases 8 and 8 are swung in the state as described above, the adjacent barrel cases 8 and 8 are swung with their 90 ° orientations being different from each other, and the inner surface of the workpiece 13 is polished. After the polishing is completed, the barrel case 8 is positioned at the workpiece take-out position. At this time, the barrel case 8 in a horizontal state as shown in FIG. 1 is first positioned. Then, the barrel lid 8a is opened, the work piece 13 is taken out, the next work piece 13 is set, and the barrel lid 8a is closed. Next, when the turret 5 is rotated 90 °, the barrel case 8 in the vertical state is positioned, so the rotation motor 15 is driven to rotate the barrel shaft 9 90 ° and stop it. After that, the same operation as described above is repeated.

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

[0011]

[Effect of the device]

 In this invention, since the adjacent barrel tanks or barrel cases of the rectangular parallelepiped shape are installed with their directions turned by 90 degrees, the workability can be prevented from being deteriorated even if the turning radius is reduced. Therefore, as compared with a conventional processing machine of this type having the same capacity, the size of the whole machine can be significantly reduced and the workability can be improved.
