Description

Ultrasonic grinder

This creation is about an ultrasonic wave grinder, which can effectively solve the defects of abrasive grinding in the conventional grinding machine, the easy accumulation of workpiece debris, and the damage of the grinding piece due to high-speed rotating friction.

According to the second figure, the conventional grinder 2 mainly drives a polishing piece 21 to rotate at a high speed by a motor (not shown) for reciprocating motion to cut the workpiece (not shown). .

However, the conventional grinder 2 still has the following disadvantages:

1. The phenomenon that the polishing piece 21 is dragged: during the process of cutting the workpiece, the friction between the polishing piece 21 and the workpiece is extremely large, which may cause the polishing piece 21 to be dragged, which seriously affects the precision of the engraving cutting. Degree and stability.

Second, the workpiece debris is easy to accumulate: the workpiece debris accompanying the cutting of the workpiece will accumulate on the abrasive sheet 21, and need to be removed or rinsed with water, which is quite troublesome and inconvenient.

3. The polishing sheet 21 is easily damaged by high-speed rotational friction: during the cutting of the workpiece, the polishing sheet 21 rotates at a high speed and rubs against the workpiece, and the high temperature is accompanied by continuous operation, which easily causes the polishing sheet 21 to be damaged. Even causing bending However, it is impossible to use and greatly reduce the service life of the abrasive sheet 21.

It can be seen that the conventional grinding machine has the disadvantage that the polishing piece 21 is dragged, the workpiece debris is easy to accumulate, and the polishing piece 21 is easily damaged by high-speed rotational friction, and is not a good designer. Improve it.

In view of the fact that the conventional grinding machine has the phenomenon that the grinding piece is dragged, the workpiece debris is easy to accumulate, and the grinding piece is easily damaged by high-speed rotating friction; therefore, the creator has long been engaged in this field based on years of experience. Efforts to study and experiment, and with the relevant academics, finally developed and designed a "supersonic grinder" of this creation.

The purpose of the present invention is to provide an ultrasonic grinder, which mainly comprises an abrasive shaft, a flushing pipe, two water outlet channels, an ultrasonic oscillator, an abrasive piece, and a motor; wherein the polishing plate is rotated The metal cylinder is driven by the belt to rotate at a high speed, and the rotating shaft of the polishing disc is a hollow tubular body, wherein the flushing pipe is connected to the flushing pipe, and a water source is connected to the end of the flushing pipe. Waiting for the water outlet to supply the water source to the polishing sheet; the ultrasonic oscillator has a high-speed vibration function, and the polishing shaft or the polishing sheet can be synchronously vibrated at high speed; the polishing sheet is high-friction The hard disk-shaped body (known as the grinding wheel) is fixed on the rotating shaft of the grinding piece; thereby, the invention can simultaneously solve the phenomenon that the grinding piece is dragged in the conventional grinding machine, the workpiece debris is easy to accumulate, and the grinding piece It is easy to be damaged due to high-speed rotating friction.

The third figure is a schematic diagram of a conventional grinder.

In order to facilitate your review committee to have a better understanding and understanding of the technical means and operation process of this creation, the following examples are combined with the drawings, which are described in detail below.

Referring to the first figure, the present invention provides an ultrasonic grinder 1 mainly comprising an abrasive sheet rotating shaft 11, a flushing pipe 12, two water outlet channels 121, an ultrasonic oscillator 13, an abrasive sheet 14, and A motor 15.

The grinding blade shaft 11 is a metal cylinder, and is driven by the motor 15 to be driven by a belt 16 to rotate at a high speed. The grinding blade shaft 11 is a hollow pipe body through which the flushing pipe 12 is connected. In the water source 3, one end of the flushing pipe 12 is provided with the water outlet holes 121, and the polishing sheet 14 is fixed at the water outlet holes 121 for the water source 3 to flow out onto the polishing sheet 14; the ultrasonic wave The oscillating device 13 has a high-speed vibration function, and the polishing plate rotating shaft 11 and the polishing piece 14 can be synchronously vibrated at high speed; the polishing piece 14 is a hard disk-shaped body with high friction (known as a grinding wheel), and is solid. It is disposed on the polishing pad rotating shaft 11.

In the present creation, the abrasive sheet rotating shaft 11 is housed in the ultrasonic oscillator 13.

Referring to the second figure, the front end of the grinding blade shaft 11 can be further provided. The first portion 111 and the second portion 112 are between the first portion 111 and the polishing pad rotating shaft 11 at a first angle A of 15 to 35 degrees, and between the second portion 112 and the first portion 111. The second angle B is between 15 and 35 degrees. When the ultrasonic oscillator 13 vibrates the polishing sheet 14 at a high speed, the abrasive sheet 14 can be effectively vibrated in a vertical direction to greatly increase the high-speed vibration of the ultrasonic oscillator 13 The effect of the abrasive sheet 14.

In the present creation, the first angle A is preferably between 25 and 30 degrees.

In the present creation, the second angle B is preferably between 25 and 30 degrees.

When the user wants to use the original cutting sawing workpiece (for example, stone, not shown), the power is first supplied to operate the motor 15 and the ultrasonic oscillator 13 to cause the motor 15 to drive the polishing shaft 11 Rotating and the ultrasonic oscillator 13 vibrates the polishing shaft 11 to interlock the high speed vibration of the polishing shaft 11 while supplying the water source 3 into the flushing pipe 12, so that the water source 3 flows out from the water outlet 121. The polishing sheet rotating shaft 11 is evenly spread on the polishing sheet rotating shaft 11, and the user can cut the workpiece by the creation.

When the workpiece is cut by using the present invention, the ultrasonic shaft oscillator 13 vibrates the polishing shaft 11 and the polishing sheet, thereby greatly reducing the friction between the polishing sheet and the workpiece, so as to effectively avoid the occurrence of the abrasive sheet during the cutting of the workpiece. The phenomenon of dragging, while improving the accuracy and stability of the engraving cutting.

In the present creation, the centrifugal force generated when the polishing sheet 14 is rotated at a high speed causes the water source 3 to be uniformly distributed along the polishing sheet 14 to the polishing sheet 14 in a radial manner. The upper and the edge of the abrasive sheet 14 are tangentially emitted, and the debris (for example, stone powder) generated by cutting and sawing the workpiece can be detached from the abrasive sheet 14, thereby effectively solving the existence of the conventional grinder. The disadvantage that the workpiece debris is easy to accumulate.

Moreover, by vibrating the polishing sheet 14 by the ultrasonic oscillator 13, the efficiency of the engraving cutting of the creation can be greatly improved by three times, and the efficiency of the engraving cutting is greatly improved; and the workpiece can be cut by vibration. The workpiece debris accompanying the process is removed from the abrasive sheet 14 to solve the disadvantage that the workpiece debris existing in the conventional grinder is easy to accumulate.

Moreover, the water source 3 can greatly reduce the high temperature generated by the abrasive sheet 14 when cutting the workpiece at a high speed, and has an excellent cooling effect, which can effectively solve the problem that the abrasive sheet existing in the conventional grinding machine is easy to rotate due to high speed. The disadvantage of damage.
