Description

[Detailed Description of the Invention] The present invention relates to an auto-revolutionary movement device for rotating and revolving a polishing disk in a polishing machine.

Conventionally, when polishing the outer circumference of a rod-shaped component 10 shown in FIG. The component 10 was sandwiched between the polishing disk and a disc facing the polishing disk, and the polishing process was performed by rotating the polishing disk.

□However, since such a conventional polishing disk is simply rotating, the parts 10 on the polishing disk are not sufficiently stirred on the disk as it rotates, resulting in very poor polishing efficiency of the parts. .

Therefore, there are drawbacks such as long polishing time and uneven polishing of parts.

This invention was devised by focusing on the above-mentioned drawbacks of the conventional technology.
The above polishing disk not only rotates, but also has its center of rotation itself.
The purpose is to obtain an auto-revolutionary motion device that performs orbital motion.

The present invention will be described below based on an embodiment shown in the accompanying drawings.

The rotation-revolution device of the present invention includes a frame 1, a bearing 2, a first rotating shaft 3, a second rotating shaft 4, a gear shaft 5 for rotating the first rotating shaft 3, and a second rotating shaft. and a drive shaft 6 that rotates the rotation shaft 4 of.

The frame 1 is formed into a pyramid shape, and a driving device such as the shaft is housed in the inner periphery 11 of the frame 1.

The upper opening has a saucer 1 having a through hole 12 in the center.
3 is installed 9 to receive the abrasive and the abrasive oil used therein.

The bearing 2 is a cylindrical bearing screwed onto the inner periphery of the frame 1, and first bearings 21 a and 21 b are attached to the inner periphery.

The first rotating shaft 3 is formed into a cylindrical shape.

A through hole 31 formed on the inner periphery thereof is provided eccentrically by α with respect to the axial center, and second bearings 32a and 32b are attached to the inner periphery.

This rotating shaft 3 is connected to the first bearings 21a and 21b.
A gear 43f formed on the upper surface of the
: The rotation of the gear shaft 5 is transmitted through the gear shaft 5.

The second rotating shaft 4 is a rod-shaped rotating shaft that is attached to the inner periphery of the second bearings 32a and 32b, and its upper and lower ends protrude from the through hole 31 of the first rotating shaft 3.

Further, the upper end portion is further connected to the saucer 1 of the frame 1.
It protrudes from the through hole 12 of No. 3, and a polishing disk 7 is attached at its tip.
is installed.

This polishing disk 7 is formed into a disk shape, and its upper surface is ground to a particularly good flatness and coated with a lapping agent or the like.

Furthermore, a universal joint 41 is formed at the lower end of the second rotating shaft 4, and via this joy/trace,
A drive shaft 6 is connected to the shaft 9 so that the second rotating shaft 4 can be driven.

The gear shaft 5 is provided penetrating through the right side of the frame 1, and is attached to a third bearing 14 with respect to the frame 1.
It is rotatably attached via the

A gear 51 and a pulley 52 that mesh with the gear 43 formed on the first rotating shaft 3 are attached to the upper and lower projecting ends of the gear shaft 5, respectively.

That is, the operation of the rotation-revolution device having the configuration of the present invention is as follows.

First, the article to be polished is placed on the upper surface of the polishing disk 7, and the fixed disk 8 (which may be a rotating disk) facing the polishing disk 7 is lowered. The article 10 is sandwiched between the abrasive disk 7 and the stationary disk 8.

In this state, when the drive shaft 6f is rotated, the second rotation shaft 4 rotates and rotates the polishing disk 7.

Next, when the gear shaft 5 is rotated, the first rotating shaft 3 is rotated via the gears 43, 51.

As a result, if we focus on the second rotating shaft 4 and refer to its movement, as is clear from FIG. 3, the center P of the second rotating shaft 4 is the center of the first rotating shaft 3. α for O
Only eccentric.

Therefore, the rotating shaft 4 takes a locus β on the circumference of a radius α around the first rotating shaft 3, and also rotates itself.

This movement is transmitted to the abrasive disk 7 and the article 10
is located between the fixed disk 8 and the polishing disk 7, and is stirred and polished.

The self-revolutionary motion device of the polishing machine of the present invention can also cut surfaces on glass, hard stone, etc. using a material holding lever 9 as shown in FIG.

That is, the material holding lever 9 is firmly fixed to the frame 1 or the like, and its tip holds the glass 9at, and the glass 9a' is brought into contact with the polishing disk 7 at a predetermined angle to polish its surface.

According to the configuration of the present invention, the second rotating shaft is mounted eccentrically with respect to the first rotating shaft, and at the same time the second rotating shaft rotates itself, the first rotating shaft is rotated. By doing so, the part is also caused to revolve around the first rotating shaft, and the parts placed between the polishing disk attached to the second rotating shaft and the fixed disk are agitated and polished. Therefore, a polishing machine with extremely high polishing efficiency can be obtained.

Therefore, the polishing work can be shortened, and at the same time, the polishing force can be uniformly applied to the parts, reducing the cost of the parts.Furthermore, in the present invention, the second rotating shaft is connected through the universal joint 14,
Since it is rotated by a drive shaft separate from the gear shaft, by appropriately using the diameter of the pulley of the gear shaft, it is possible to vary the rotation speed of the gear shaft regardless of the rotation of the second rotating shaft. be.

Therefore, this makes it possible to select a polishing speed that takes full advantage of the characteristics of the part to be polished, and the effect is tremendous.
