Description

[Detailed description of the invention] The present invention relates to a polishing device, in which vibrations generated by an oscillator installed in an annular polishing tank cause frictional sliding and flow between the abrasive material in the polishing tank and the object to be polished, resulting in a polishing process. The purpose is to improve vibration-type polishing equipment.

Conventionally, this type of vibrating polishing apparatus has a single vibrating motor attached to the center of the lower part of the polishing tank, and performs a polishing operation by vibration force generated by an eccentric member attached to the motor shaft.

Therefore, although this configuration is suitable for small-scale polishing operations, it is not suitable for large-scale polishing equipment that requires a strong vibration source.

In other words, not only is there a limit to the size of the vibration motor itself, but in order to increase the vibration force, it is necessary to swing a large unbalanced weight, which inevitably requires an increase in the horsepower of the vibration motor. This increases its own weight and impairs its durability.

Furthermore, as the weight of the vibration motor increases, the vibration force acting on the polishing tank also weakens, necessitating a motor with even greater horsepower, creating a vicious cycle that limits its use.

As described above, a polishing apparatus equipped with one built-in vibration motor has a problem in that it is not possible to increase the size of the apparatus.

The present invention aims to solve these problems and provide a large-sized polishing device, in which the vibration generator is configured separately from the drive source such as an electric motor, and the polishing device has a polishing speed of 1,000 to 10,000, which was previously impossible. This makes it possible to construct a device that can be expanded to a large capacity.

Embodiments of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes an annular polishing tank having a convex portion 1a in the center, and this polishing tank 1 is installed on a base 4 supported by a pedestal 3 via an elastic mount 2 such as a spring.

At the bottom of the polishing tank 1, a plurality of unbalanced weights 6a, 6b and a transmission wheel 7 (three in the embodiment) are mounted on a shaft 5a which is mounted on the base 4 via bearings 8at8b. The oscillator A is configured and the transmission wheels 7, 7 of each oscillator A are rotatably connected via a belt or chain 13.

In addition, the motor 9 can be placed at any position outside the polishing tank 1, such as the side surface of the stand 3.
The transmission wheel 11 which is fixed to the motor shaft and the transmission wheel 7 of one of the oscillation device A described above are rotationally connected by a belt or chain 12.

In the polishing apparatus having the above configuration, when the motor 9 is operated, the total oscillation device A,
A, A's transmission wheel? , 7.7 are rotated, and as a result of the rotation, the unbalanced weights 6a, 6be have an oscillating force, and the polishing tank 1 is vibrated by the vibration force.

Therefore, this vibration generates flow, friction, and sliding force, and this force causes the abrasive material and the object to be polished in the polishing tank 1 to undergo a polishing process.

Furthermore, since the plurality of oscillation devices A are connected to each other,
The amplitude of each oscillation device A can be changed, and the generated frequencies can be adjusted to be synchronous or asynchronous, and it is possible to generate a desired vibration in the polishing tank 1.

As mentioned above, in this invention, since the motor is fixed outside the polishing tank, vibrations are not transmitted to the motor, providing long-term durability and being economical.The capacity of the polishing tank can be varied from small to large. Even the mold can be configured freely.

In addition, even when multiple oscillation devices are installed, according to the present invention, all the oscillation devices can be rotatably connected and driven by one motor having the total driving capacity of all the oscillation devices, resulting in a large capacity. The weight of the polishing device can be reduced, and if multiple oscillation devices are installed, the weight will be about one-third of that of the vibration motor, so the energy consumed by the weight can be saved. increases.

Therefore, the capacity and horsepower of the motor can be reduced by reducing the vibrating parts including the polishing tank, contributing to energy saving and cost reduction.

In addition, by rotatably connecting the oscillating device with a belt or chain, the motor can be installed and driven at an appropriate position outside the polishing tank, which allows the height of the device to be lowered and is suitable for large-sized devices. The practical effects of implementing the present invention are extremely large, since the device has features such as being able to be designed to have a low height.
