Description

[Detailed Description of the Invention] The present invention relates to an improvement of a vibratory buffing device that buffs the bottom surface of an article placed on a horizontal buffing surface by vibration and rotation of the buff, and particularly relates to an improvement of a vibrating buffing device that buffs the bottom surface of an article placed on a horizontal buffing surface. The present invention relates to a vibrating buffing device that can forcibly move the oscillator.

Generally, a vibrating buffing device is used to vibrate a horizontal buffing surface to buff the bottom surface of an article (metal, non-metal, etc.) placed on it to give a base finish or shine.

However, with conventional vibrating buffing equipment, there is no problem as long as the object to be buffed is small and can be moved smoothly by the vibration of the buffing surface. If the contact area with the hub surface is large and angular, the frictional force between the object and the buffing surface is large, making it difficult to move due to vibration, and it takes a long time to complete buffing.
This had the disadvantage of reducing polishing efficiency.

The present invention has been made for the purpose of solving the above-mentioned drawbacks and providing a vibratory buffing device that can efficiently buff the material to be buffed, regardless of its shape and size.

In other words, the vibratory buff polishing device of the present invention is configured to forcibly move an article placed on a horizontal buffing surface using a free rotation promotion ring that rotates the article using the vibration force during polishing. A detailed explanation will be given below using an embodiment shown in the drawings.

FIG. 1 is a partially cutaway front view of the vibration buff polishing apparatus of the present invention. The vibration buff polishing apparatus comprises a fixed table 1 and a vibration force generating mechanism 2 mounted on the fixed table 1.
The polishing device is composed of a movable table 5 supported at its upper part so as to be able to produce a predetermined vibration, a buff 6 placed horizontally and freely on the upper surface of the movable table 5, a ring-shaped surrounding ring 7 which surrounds the periphery of the buff 6 and prevents the material to be polished placed on it from falling off, and a free rotation promoting ring 8 which can be fitted into and detached from the surrounding ring 7 and which can rotate freely in synchronization with the buff 6, and the free rotation promoting ring 8 forcibly moves the object on the buff surface, thereby improving the polishing efficiency.

The vibration generating mechanism 2 is composed of an electromagnetic coil 3 and an appropriate number of leaf springs 4 whose lower ends are fixed so as to face the electromagnetic coil 3 at a predetermined angle, and whose upper ends are connected to the movable base 5. By energizing the electromagnetic coil 3, the upper part of the leaf spring 4 moves repeatedly within a predetermined range, thereby making it possible to vibrate the movable base 5.

As shown in FIGS. 2 and 3, the free rotation promoting ring 8 includes two large and small plate-shaped rings 9 and 10 each having a predetermined height arranged concentrically and interposed in the diametrical direction between the two rings. The plate-shaped outer ring 9 is made as large in diameter as possible within the surrounding ring 7, and the plate-shaped inner ring 10 is connected integrally with the plate-shaped outer ring 9 by a partition wall 11 provided therein. The plate-shaped inner ring 10 and the partition wall 11 have a diameter dimension that divides the inner space into approximately half, and the lower ends of the plate-shaped inner ring 10 and the partition wall 11 are connected to the plate-shaped outer ring 9 so as not to touch the buff 6 surface. It is arranged and configured slightly higher than the 9 sole.

Therefore, when the free rotation promoting ring 8 receives regular vibrations from the buff 6, it rotates due to the relationship between the vibrations and the frictional resistance of the outer ring 9.

In the above embodiment, the free rotation promoting ring 8 is removed from the outside.
Although the structure is shown as being composed of meat rings 9, 10 and a partition wall 11 connecting these, and partitioned so that the material to be polished can be loaded into the outer and inner rings 9, 10 as appropriate depending on the size of the material to be polished, The main purpose of the present invention is to forcibly move the material to be polished, and the effect will be the same if it has a partition wall that divides the inside of the outer ring into an appropriate number of spaces.

(Example) The present invention was applied to two types of polished steel material A, which weighs 940 g and has a length of 120 mm, width of 50 mm, and height of 20 mm, and steel polished material B that weighs 400 g and has a length of 50 mm, width of 50 mm, and height of 20 mm. As a result of buffing using a vibrating buff polishing device of Material A is polished for 220 minutes, material B is polished for 120 minutes.
I was able to perform the required polishing in minutes.

As described above, the present invention improves polishing efficiency by forcibly moving the material to be polished placed on a horizontal buffing surface using a free rotation promotion ring that uses the vibration force during polishing to rotate freely. This method has the advantage of being able to improve buffing by about 1.3 times compared to conventional methods, and also allowing efficient buffing regardless of the size of the material to be polished.

Therefore, the proposed vibratory hub polishing device has great utility value.
