Abstract

(57) Abstract: To provide a simple device for grinding abrasive particles by blowing them with high pressure air. A hollow cylindrical main body 12, a nozzle member 14 attached to the other end of the main body 12, and a pipe 16 connected to the hollow cylindrical main body 12 for supplying abrasive grains. It is designed to be attached to the tip of a commercially available air gun.

Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to an air gun attachment for grinding, and more particularly, to an attachment attached to an air gun for blowing fine particles of abrasive material onto a work piece by a high pressure air flow from the air gun for processing.

[0002]

[Prior art]

 It has been widely practiced in the past to polish or engrave metal, glass, stone or the like by placing a fine abrasive material, that is, abrasive particles, on a pressurized air stream and spraying it onto a metal or other processed product.

[0003]

[Problems to be solved by the device]

 However, the conventional device of this type has a disadvantage that the entire device is complicated and cannot be easily operated.

In consideration of such a problem, the present invention attaches to a pistol type air gun which is generally available on the market so that the trigger of the air gun can be touched without any special troublesome operation. It is intended to provide an air gun attachment for grinding, which is capable of performing desired grinding, etching, or paint removal treatment on various kinds of workpieces such as metal, glass, stone, etc. by ejecting high-pressure air.

[0005]

[Means for solving the problem]

 In order to achieve this purpose, the grinding air gun attachment of the present invention comprises a hollow cylindrical main body that is screw-fitted to the jet end of a commercially available pistol type air gun, and a pipe connecting member fixed to the side surface of this cylindrical body. , A flexible pipe attached to the pipe connection.

[0006]

【Example】

 A preferred embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is an elevational view showing a state in which a grinding air gun attachment 10 of the present invention is attached to a commercially available pistol type air gun A.

In the commercially available pistol type air gun A, the lower end of the handle portion H is connected to a compressed air source (not shown) by a hose or a pipe P, and a trigger T provided on the handle portion H is operated. As a result, compressed air is ejected from the nozzle N at the tip of the barrel B. A screw S is provided at the tip of the barrel B of the air gun A so that various nozzles can be attached and detached as required.

By the way, the grinding air gun attachment 10 of the present invention has one end attached using the screw S of the barrel B of the air gun A, and as shown in FIG. , A nozzle member 14 attached to the other end of the main body 12, and a pipe 16 connected to the hollow cylindrical main body 12 for supplying abrasive grains.

A first screw 18 for fitting with the screw S of the barrel B of the air gun A is cut at one end of the hollow cylindrical main body 12, and the second screw is also provided at the other end. 20 is cut so that the nozzle member 14 can be fitted therein.

A threaded opening 22 is formed at the center lower end of the hollow cylindrical main body 12, and a joint 24 fixed to one end of a pipe 16 for supplying abrasive grains can be fitted therein. The other end of the pipe 16 is to be inserted into a container V containing abrasive grains.

[0011]

[Effect of device]

 As can be easily understood from the above description, the air gun attachment 10 for grinding according to the present invention has the attachment 10 attached to the air gun A, and the end of the pipe 16 is inserted into a container containing abrasive grains. When the trigger T is operated, high-pressure air passes through the barrel B of the air gun A and passes through the hollow cylindrical main body 12 of the attachment 10, so that a container containing abrasive grains passes through the pipe 16 connected to the main body 12. Abrasive grains are sucked from V and are entrained in the high-pressure air in the main body 12 and ejected from the nozzle member 14.

Therefore, the tip of the nozzle member 14 of the air gun attachment 10 for grinding according to the present invention is subjected to various kinds of grinding using abrasive grains, for example, removal of paint, inscription or engraving of metal, wood, stone or glass, etc. It is extremely easy to remove burrs from castings.
