Description

Air vibrator

The present invention relates to an engine moving device for generating vibration by air supply, and more specifically, by the piston for reciprocating the upper and lower compression chambers of the air gas cylinder supplied with a reciprocating piston in the cylinder. The present invention relates to an erosion control device generated by opening and closing a compression chamber to repeat raising and lowering by air pressure.

The general vibrating device is based on a rotating shaft which rotates by a DC current applied to a driving motor, an eccentric cam and an eccentric plate which are rotated by forming an eccentric cam and an eccentric plate on the rotating shaft or a driving shaft driven by power.

As the eccentric plate rotates to show the inertia difference, vibration is generated, and the vibration is transmitted to the object through the bracket supporting the motor.

In addition, the eccentric cam is moved up and down by the follower, and it is extremely common configuration to vibrate the object provided in the follower.

The conventional vibration generating device configured as described above is largely large in size and cannot be used in a narrow space, and requires a specific means of supplying electricity by using a motor by a power source.

Accordingly, in the Republic of Korea Patent No. 10-0357699, the piston inside the cylinder composed of the cylinder and the piston passes from the upper surface of the piston and the pressure slide portion composed of a relatively large diameter pressure slide portion and a relatively small rod portion to a predetermined point of the rod portion. Drilling an air guide hole, the guide hole having an air inlet hole to the outer surface of the rod portion;

The inner diameter of the cylinder is composed of a first inner diameter portion in which the pressure slide portion of the piston is inserted in close contact and a second inner diameter portion in which the rod portion is inserted in close contact, and an air inflow hole into which external air flows corresponds to the first inner diameter portion. The air discharge hole formed through the cylinder side wall and air is discharged is formed through the cylinder side wall corresponding to the second inner diameter portion.

Accordingly, the air introduced into the air inlet hole advances the piston while entering the first inner diameter part of the cylinder through the air inlet hole and the air guide hole of the rod part exposed downward while lowering the piston.

The piston advanced by the above is discharged to this air discharge hole as the air inlet hole and the air discharge hole intersects, and the piston rod is repeatedly lowered by repeatedly introducing the air into the air inlet hole like electricity. To generate vibration.

This configuration is composed of a cylinder body portion and a fastening body portion fastened to the body portion is coupled to the piston coupled to the plurality of air flow paths formed in the cylinder and the air guide hole formed in the piston, such as the complicated manufacturing disadvantages In particular, the piston, which is moved by pneumatic pressure, transfers to the first inner diameter part by pneumatic pressure, while in lifting and lowering, it is extremely difficult to provide air pressure to the first inner diameter part in the reverse state of the piston which divided the cylinder. The disadvantage of not being able to accurately transport and also the disadvantage of having a problem of lack of force in lifting when there is a weight is caused.

Due to these shortcomings, the selection can not generate fast and accurate tremors and is difficult to use in precision machines.

In particular, when the piston is raised and lowered in the lowered state, the air pressure is raised and lowered in the state of being extremely low, when it is configured to a large force or a heavy object has a disadvantage in that it is not effective to perform the lifting action and failure and tremor.

The present invention has been proposed to improve the above problems, and in particular, its purpose is to make it possible to use it in a narrow place, and to make it easy to manufacture by the simple configuration of the cylinder and the piston, and to raise or lower the piston. It is intended to provide the necessary traction force by providing the upper and lower parts of the piston, to generate precise vibration according to the precise valve action, to be used in precision machinery, and to attach a silencer to prevent noise. .

The present invention for achieving the object is provided with a cylinder reciprocating piston, divided into a first pressurized chamber and a second pressurized chamber extended than the first pressurized chamber in close contact with the piston in the cylinder and the air supply to the upper end of the first pressurizing chamber Form a ball.

In addition, a silencer is formed by drilling an exhaust valve hole in the inner wall of the second pressure chamber. The piston valve is configured to open and close the first and second pressure chambers on both side surfaces of the piston.
