Abstract

PURPOSE:To permit to effect two processes of grinding work, having different qualities, continuously without carrying out the replacement of the contents of a barrel by a method wherein the barrel is rotated or revolved under a high- speed planetary revolution. CONSTITUTION:When the predetermined amount of work pieces and abrasive agent are enclosed into the barrel 9 and a motor 14 is started, a turret 5 rotates into the arrow sign (a) direction and the barrel 9 is revolved about a shaft 22 while the shaft of a disc is rotated into the arrow sign (b) direction. The barrel 9 revolves about the shaft of the turret and rotates by the shaft of the disc, therefore, mass in the barrel 9 flows and moves by a centrifugal force and thereby carrying out the high-speed planetary revolution barrel grinding of the work pieces.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a barrel polishing apparatus that can be used in either a high speed planetary rotating barrel polisher or a rotary barrel polisher, and in either case operates as a three stage buntle.

Conventional high-speed planetary rotating barrel polishing has been widely used due to its high processing efficiency, but there is a limit to the surface roughness of the processed workpiece due to the abrasive material charged into the barrel tank, and once it reaches a certain roughness, I can't hope for any further improvement. On the other hand, rotating barrel polishing has a low processing efficiency, but is characterized by greatly improving the surface roughness of the processed workpiece.

Therefore, if two processes of rough finishing and gloss finishing are required, perform the rough finishing with high-speed planetary rotating barrel polishing, then replace the abrasive with a glossy one and perform gloss finishing, or alternatively perform the rough finishing with high-speed planetary rotating barrel polishing. After that, the contents are transferred to a rotating barrel tank and a different type of rotating barrel polishing is performed, so replacing the contents takes time and requires a lot of effort. Furthermore, the use of a high-speed planetary rotating barrel polishing machine and a rotating barrel polishing machine improves surface roughness, but has the disadvantage of requiring a large installation area and being expensive.

However, according to this invention, the turret can be mounted so that the barrel tank can rotate and revolve (that is, perform planetary rotation motion), and the barrel tank can be rotated around its axis while the turret is fixed. Since it is designed to be able to rotate on its own axis, not only can the seven machines be used to selectively use either the high-speed planetary rotating barrel polishing method or the rotary barrel polishing method, but also a three-stage action can be used in either case, if necessary. You can choose the shape of the barrel to suit your needs.

In addition, the turret is rotated on its axis and revolves around the barrel tank charged with the workpiece, abrasive material, water and compound if required, and the workpiece is rough-finished by rotating the turret at high speed, and then the turret is stopped and the barrel tank is then opened. By rotating the machine, the workpiece can be finished with a glossy finish using the same abrasive material. Also, in contrast to this method, after polishing using the rotating barrel polishing method,
Subsequently, polishing using the same abrasive material can be performed using a high-speed planetary rotating barrel polishing method. In this way, we have achieved an ideal barrel polishing device that solves all of the above-mentioned drawbacks of the conventional barrel polishing device, allowing polishing of different properties to be performed continuously without replacing the contents (hereinafter referred to as mass). It was extremely successful.

Next, details of the invention will be explained with reference to the attached figures. 1st
2 and 2 are a partially cutaway front view and a plan view of the apparatus for implementing the present invention, and FIG. 3 is a view of the barrel tank.

That is, the housing l is a hollow box made of an iron plate, and the lower end of the coolet shaft to which the timing pulley or sprocket (timing pulley or sprocket) K is fixed is inserted into the boss 3 at the center of the bottom plate /a, and the coolet is installed at the upper end. 1 (disc-shaped) is attached rotatably. A plurality of bearings 6a are mounted on the same circumference around the turret shaft on the circumference of the upper surface of the cooler at equal intervals and parallel to the turret shaft (in this embodiment, two bearings are used). (As shown in FIG. 4, however, the optimum number is usually 1).The lower end of the circular plate shaft is rotatably inserted into the bearing 2, 4a. A disc g is mounted on the upper end of the disc shaft 7 parallel to the turret 5, and a barrel tank 9 is rotatably supported on the disc g so as to be rotatable around a barrel shaft 10 parallel to the turret shaft. A small bevel gear // is fixed to the center side of the turret at one end of the barrel shaft 10 of the barrel tank wa. The shape of the barrel tank 9 is shown in FIGS. 1, 2, and 3.

In this way, the plan view of the barrel tank, as shown in the figure,
Both the elevation view and the side view have the same shape, and in the case of a rotating barrel (rotation with the barrel axis 70 as the rotation axis) and in the case of a high-speed planetary rotating barrel (the revolution axis is the turret axis and the rotation axis is the disk axis 7). Even in the case of planetary rotation (planetary rotation), the slope shown in the figure forms a so-called three-stage action barrel that performs an appropriate stirring action, providing an action force that improves polishing efficiency. /2 in the figure is the lid of the barrel tank.

A timing pulley or sprocket/3 is fixed to the lower end of the disk shaft 7, and the timing pulley or sprocket/3 is interlocked with the timing pulley or sprocket by a timing belt or chain 27. Further, the turret 5 is rotated via a pulley 3 of a variable speed motor with a brake installed on one side of the casing and a belt 6 attached to a side wall groove of the turret 5. On the other hand, a bearing /8 that rotatably supports the cylinder /7 is located above the housing /. The cylinder 17 has a keyway /q of a certain length inside thereof, and the keyway /9 engages with the key 2/ of the sliding rotation shaft 20 fitted into the cylinder /7. . Therefore, the sliding rotation shaft O can slide within the cylinder/7 for a certain length. Further, it is configured to be able to rotate together with the cylinder/7 within the bearing 7g. A boo IJ-22 is fixed to the upper end of the cylinder 17. The pulley 22 is a variable speed motor=23,
It is rotated via belt J. A large bevel gear 23 is fixed to the lower end of the sliding rotation shaft 20, and the small bevel gears //, /
/ can be meshed with each other. Also, the sliding rotation shaft, 2
The upper end of the piston rod 30 of the hydraulic cylinder
is fixed to the tip of.

In addition, the timing pulley or sprocket tag, /3
Also, the drive by the timing belt or chain 27 can be made into a 7-drive by gears with no slack or slack. Further, in the above embodiments, the body is constituted by a casing, but it is also possible to provide a casing as a cover around the outer periphery of a normal frame-like body.

The operation of the present invention will be explained below according to the above structure.

The apparatus of the present invention can perform various polishing methods such as high-speed planetary rotating barrel polishing only, rotating barrel polishing only, rotating barrel polishing that is continuous with high-speed rotating barrel polishing, or high-speed planetary rotating barrel polishing that is continuous with rotating barrel polishing. Here, this invention will be described in terms of continuous rotating barrel polishing rather than high-speed rotating barrel polishing, which is easiest to understand.

A predetermined amount of the workpiece, abrasive material, water and compound if necessary are added into the barrel tank, and the lid/2 is attached and sealed. Once all barrel tanks are ready, hit the brakes and start the variable speed motor/lay. On this occasion,
It is assumed that the large bevel gear is rising and falling and is not meshing with the small bevel gears // and //. When the motor puffer is started, the turret 5 rotates in the direction of arrow a as shown in FIG. It is rotated in the direction indicated by the arrow in the figure. It is optimal to select the ratio n/N of the revolution number N and the rotation number n of this barrel tank 9 to -7. In addition, the number of revolutions of the barrel tank in this case is bO-2oo/min when the revolution radius of the barrel tank is R (m).
Good results can be obtained by selecting a ball rotation of Q rotations, optimally ioo to 80X per minute. Since the barrel tank 9 revolves around the turret shaft and also rotates on its own axis about the disk shaft 7, the mass in the barrel tank 9 flows centrifugally, and the workpiece is subjected to high-speed planetary rotation barrel polishing.

In the device of this invention, when the barrel tank is rotated horizontally as shown in Figs. 1 and 2, the mass rises toward the outer circumference of the inner wall of the barrel tank for pest control at the same time as the start, compared to a device that rotates vertically. It is also possible to rotate the turret with the left side vertical, i.e., with the barrel trough vertical, although this has the advantage of less start-up time and less shock when stopping. When the first step is completed, stop the variable speed motor using the brake gear.

This stop is performed by a proximity switch or a photoelectric switch (not shown) between the small bevel gear // and the large bevel gear 2.
It stops at a position (the position shown in FIGS. 1 and 2) where it can mesh accurately with j. When the piston of the fluid pressure cylinder 2B is stopped at the fixed position, pressure fluid is introduced to lower the sliding rotation shaft 20 and the large bevel gear 2.5, and the small bevel gear 2.5 is lowered.
mesh with. Next, start variable speed motor 23.

The sliding rotation shaft 20 and the large bevel gear 2 are rotated. This rotation causes the small bevel gear 2j to mesh with the large bevel gear 2j.
/ and the barrel 10 rotates as shown by arrow C in FIG.
The barrel bath 9 is rotated vertically, and the workpiece is subjected to normal rotating barrel polishing. The rotation speed of this barrel is /S~3o/min when the radius of the inscribed circle of the barrel tank is r (e).
Good results can be obtained by selecting J"H rotations, most preferably /g-xs/(n rotations per minute. When the second step is completed, the variable speed motor 23 is stopped, and the lid of the barrel tank is closed. 2
is removed, the barrel tank is rotated, and the mass is discharged onto a vibration sorter (not shown) for sorting, thus completing one cycle.

In addition, in the above-mentioned embodiment, a plurality of barrel tanks are connected to a motor,
2.3-1 Although the rotation is made only by driving, it is obvious that a motor may be installed in each of a plurality of barrel tanks to drive the barrel tanks, and this falls within the technical scope of the present invention. It is something.

As described above, the present invention not only can be used with either a high-speed planetary rotating barrel polishing machine or a rotary barrel polishing machine, but can also be configured to have a triple-function barrel in either case, and can be used with up to 7 machines. This machine can perform a wide variety of polishing tasks. In addition, when rotating the turret horizontally, the barrel tank will rotate horizontally during high-speed planetary rotating barrel polishing.
It has advantages such as no dents, chips, or cracks on the workpiece.
