Abstract

The present invention relates to a rotary nozzle for cleaning, which is able to efficiently and rapidly clean waste attached on the inner side of a workpiece forming a circular or polygonal tubular body by being processed with various kinds of machine tools such as a CNC automatic lathe and a machine center. More specifically, the rotary nozzle for cleaning the inside of a machine tool workpiece is able to remove waste from the inner side of the workpiece by rotating compressed air. The rotary nozzle comprises: a connection tubular body which is combined with a center hole between connectors having a screw part in the central part in order to be combined with the air discharge unit of an air conditioner through a screw; and a rotary nozzle body which sprays compressed air to the outer circumference by being combined with the front end part of the connection tubular body.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a rotary nozzle for cleaning an inner surface of a workpiece of a machine tool,

The present invention relates to a cleaning rotary nozzle which is manufactured by machining a variety of machine tools such as a CNC automatic lathe and a machine center so as to effectively and quickly clean processing residue attached to the inner surface of a workpiece forming a circular or polygonal tubular body More specifically, it comprises a connector attached to the compressed air discharging portion of the air gun, a connecting tube body rotating in association with the connector, and a rotating nozzle body coupled to the leading end of the connecting tube body to spray the compressed air to the outer circumference. It is characterized by being constructed so that the residue can be cleaned in a short time.

Conventionally, an air gun is used to clean the residue attached to the inner surface of the work.

However, since the air gun supplies the compressed air to the surface of the workpiece in a straight line to forcefully separate the residue attached to the surface, there is a problem that the person has to rotate the air gun so that a large amount of force is required when cleaning a large amount of workpieces. There is an inconvenience that the efficiency of the washing operation is lowered because the accuracy of the work is lowered.

The present invention has been developed in order to solve the above inconvenience.

The present invention relates to an air gun, which comprises a connector having a threaded portion formed at the central portion thereof so as to be screwed to the air discharge portion of the air gun, a connecting tube body rotatably coupled to the center hole of the connector of the connector and a rotary nozzle connected to the connecting tube front end, So that the debris attached to the inner surface of the workpiece can be removed by the rotating compressed air.

When the connecting part of the connector is connected to the screw connecting part formed in the air gun compressed air discharging part, compressed air is supplied to the connecting center hole, and the connecting tube body inserted into the connecting part of the connecting part is connected to the peripheral wall of the connecting part and the bearing And a plurality of compressed air injection holes having a predetermined angle are formed in the peripheral wall of the connection pipe of the nozzle body coupled to the tip end of the connection tube body so that compressed air is supplied to the center hole of the connector and connected to the nozzle body The nozzle body rotates according to the angle of the compressed air injection hole, so that the compressed air supplied from the air gun rotates on the inner surface of the workpiece, so that the compressed air also rotates while rotating the workpiece It can be cleaned by blowing off the residue in a short time by touching the surface. The can has the advantage that a person can be in there is no need to rotate the gun to get the benefits that can relieve the fatigue of the people to improve work efficiency.

In addition, since the connector body of the present invention is coupled with the connector and the bearing, and rotates in place, and is coupled with the snap ring (S), the compressed air is stably prevented from being exposed to the packing Can be managed.
