DETAILED DESCRIPTION OF THE INVENTION The present invention can be used in either a high-speed planetary rotating barrel polisher or a rotary barrel polisher, and provides: Related.

Conventional 8-speed planetary rotating barrel polishing has been widely used due to its high processing efficiency, but is it charged into a barrel tank? If there is a limit to the surface roughness of a workpiece processed by polishing, etc., and once a certain roughness is reached, the surface rIliII
cannot be expected to improve. On the other hand, rotary bar 1-nor ω1 polishing has a low machining efficiency, but is characterized by greatly improving the surface roughness of the machined workpiece.

Therefore, if two steps of roughening and gloss finishing are required,
Perform a rough finish with high-speed planetary rotating barrel rtll polishing, then polish (replace A with a glossy one to achieve a glossy finish, or perform a rough finish with high-speed planetary rotating barrel polishing, then transfer the contents to the rotating barrel tank l \In addition, since we use a different type of rotating barrel polishing, it takes time and a lot of effort to replace the contents.Also, high-speed planetary rotating barrel polishing Di IIXI and rotating barrel polishing 1 The surface roughness 4) can be improved, but the problem is that it requires a large installation area and is expensive.

However, according to this invention, the barrel tank can be mounted on the turret so that it can rotate and revolve (that is, perform planetary rotation motion), and the barrel tank can be mounted on the turret while being fixed to the turret. Because it can rotate around its axis, it is not only possible to use a high-speed planetary rotating barrel polishing method or a rotating barrel polishing method as needed with one device, but also allows In this case, the shape of the barrel can also be selected to provide three-stage action.

In addition, 7 [turret that rotates and revolves the barrel tank charged with water and U pound to cover crops and rtll abrasive material] - is rotated on a high-speed planetary cycle, and after roughly finishing the crop, the turret is stopped. Then, the workpiece can be polished (L-1) by rotating the barrel tank and polishing the workpiece.Also, contrary to this method, the rotating barrel ■σ
After performing the polishing process using the 1 polishing method, it is also possible to perform the polishing process using the high speed planetary rotating barrel rilIIP' method in the same polishing mill. In this way, without replacing the contents (hereinafter referred to as cells),
Ti1l polishing 1- with a difference of 2]- can be continued at °C. Furthermore, this invention provides a tapered notch at the tip of the barrel shaft, and installs a gear housing that allows the drive device to move to the right so that it can be freely disposed of, and transmits the driving force to large and small bevel gears within the gear housing. C
A rotary shaft for transmission is made to protrude from the mountain p, and a tapered portion of the tip of the rotary shaft engages with a notch in the barrel shaft. It can be reliably engaged even if there is some deviation from stopping at the fixed position, and there is no risk of damaging the drive device, making it extremely robust and highly safe.

Although the fuselage is constructed as follows, it is also possible to provide a cover-bound casing around the outer periphery of a normal frame-shaped fuselage.

The operation of the present invention will be explained below in accordance with the above 414 instructions. The apparatus of this invention can be used for many different types of polishing, such as high-speed planetary rotating barrel polishing only, rotating barrel 1tll polishing only, rotating barrel polishing that is continuous from high-speed rotating barrel polishing, or high-speed planetary rotating barrel jll polishing that is continuous from rotating barrel rill polishing, etc. However, the best way to understand this invention is to describe the continuous rotating barrel polishing process rather than the high-speed rotating barrel polishing process.

A predetermined number of workpieces, a TiJl polishing abrasive, water and compound if necessary are added to the barrel tank 9, and the sill 12 is removed and sealed. Once all the barrel tanks 9 have been prepared, the variable speed motor 14 with brake is started.

At this time, 1) the 11th gear wheel 17 is -F as shown in FIG.
li:1, and the engagement between the tapered portion 22 and the notch 21 is released. The motor 1/l 9 (1 movement rotates the turret [-5 in the direction of arrow a as shown in FIG. The barrel tank 9 is rotated in the direction Ij indicated by the arrow in the figure by the bells 1 to 27.The number of revolutions N and the number of rotations 11 of this barrel tank 9
The ratio +1/N is - and the rotation speed of the rotor 30 is l! Although J can be selected as appropriate, it is optimal to stop the rotation of the motor 30 and select -r+1/N to be -1. In addition, the number of revolutions of the barrel tank 9 in this case is 60 to 11.1 per minute, where the revolution radius of the barrel tank is R (m ).

If you select 0, -φ main rotation, the result is good/, 111
It will be done. The barrel tank 9 is located between the shaft 2 of the turret 4')
Since the support shaft 7'-C rotates on its own axis, the mass in the barrel tank 9 flows centrifugally, and the workpiece (1) undergoes high-speed rotating barrel polishing.

The apparatus of this invention is shown in FIGS. 1 and 2, in which two barrel tanks are rotated horizontally.

At the same time as the movement, the mass gradually stands closer to the outer circumference of the inner wall of the barrel tank, so compared to the case of vertical rotation, the mass starts 11J11. !
l and f'Pi when stopped? ! However, it has the advantage that the turrets 1 to 5 are vertical, that is, the barrel tank 9 can be rotated vertically (one rotation).
The brake (=j) stops the variable speed motor 14. This stop is caused by the proximity switch 33 pressing the dog 3 on the turret 5.
5 and stops at a position where the tapered portion 22 and the notch 21 can engage. If it does not stop at the fixed position, pressurized fluid is inserted into the piston side of the fluid pressure cylinder 26, the piston rod 24 is pushed out, the gear housing 17 is raised, and the rotating shaft 19 is moved up.
The tapered portion 22 of the barrel shaft 10 is engaged with the tapered notch 21 of the barrel shaft 10. At this time, even if there is some deviation, they are both tapered and flexible joins 1 to 37
Since they are connected by , they can be engaged reliably.

Next, the solenoid 36 is activated to release the knock 31 that fixed the barrel shaft 10. Next, the variable speed motor 23
and avoid rotation of the rotating shaft 20 and the large umbrella 1225. Due to this rotation, the small bevel gear 11 and the barrel shaft 10 meshing with the large bevel gear 25 are shown by the arrow C in FIG.
The barrel tank 9 is rotated in the vertical direction, and the workpiece is subjected to normal rotating barrel IJI polishing. The rotation speed of this barrel is 15 to 3074 loaves per minute, with the radius of the inscribed circle of the barrel tank being r (m), and optimally it is -25 to '18 per minute. Good results can be obtained by selecting d-rotation. can get.

When the second culm is finished, the variable speed converter 23 is stopped, the barrel 112 of the barrel tank 9 is removed, and the barrel tank 9 rotates to move the mass into the sorting machine (not shown). construction)
Take out the JJF upwards and sort it, and close the barrel tank 9 to suit r'f
3) 2 and dog 3/l stop at the fixed position and 1 league cycle is completed.

Furthermore, Maej! In the embodiment, a plurality of barrel tanks 9 are rotated by only one drive of the motor 23, but only several barrels iv! You may install a large number of motors corresponding to each of the floats inside the float tube. It is also obvious that a C inverter (=J motor) can be used instead of the variable speed motor mentioned above.Furthermore, in the above embodiment, the turret shaft is installed in the large part of the housing, The barrel tank was suspended, but the turret shaft was installed at the bottom of the housing to support the barrel tank (174+I), that is, the state shown in Figure 1 is upside down. If it is set like this, the durability of the bearing which dries the support shaft is good.

Next, in the embodiment, the notch in the barrel shaft 10,
The engaging and disengaging mechanism is connected to the tapered part 22 at the end of the rotating shaft 19)
Although M is constructed, it is not limited to this specific structure. For example, the cutout and taper portion may be reversed, or other known connection means may be used. The point is that it is only necessary to transmit the rotational force through connection and to control the position.

As mentioned above, this invention not only can be used for high-speed planetary rotating barrel polishing machine or rotating barrel polishing machine for Nodora, but also can be used for any dogishi triple-function barrel (1). A wide variety of rJI polishing can be performed with one machine.In addition, when the turret 1- is rotated horizontally, the barrel tank is rotated horizontally, so the workpiece can be polished at high speed. It has advantages such as no dents, chips, or cracks.
