Description

Technical Field [0001] The present invention relates to a cleaning device for foreign matter,

In general, machined parts made by machining a metal machine are manufactured by machining, casting, welding, etc. Particularly, machining methods for manufacturing metal machine parts can be roughly divided into plastic working and cutting machining.

In other words, plastic working is a processing method in which parts are deformed through various processes such as forging, rolling, extruding, drawing, tubing, rolling, pressing, etc., and the cutting process is performed by a lathe, And cutting and removing a part of the machined part by using a drilling machine or the like.

Recently, the cutting process has been performed through NC machining using numerical control according to the technological development. Such NC machining has advantages that the numerical value of the product is accurate, the safety accident of the worker is reduced, and the mass production of the product is possible .

On the other hand, machined parts produced through such machining process generate a large amount of large and small chips in the machining step. In this process, frictional heat is generated between the tool and the machined part, The cutting oil is supplied to the machining part so as to prevent damage.

Therefore, in the processing step of the machined part, foreign substances such as crusher, chip, and machining oil are adhered to the surface of the machined part. In order to commercialize the machined part or to carry out subsequent processing such as sanding or painting, such foreign matter must be removed.

Accordingly, as a prior art for removing foreign substances from a conventional machining part, there is disclosed in Korean Patent Registration No. 10-0923563 entitled " Bearing Automatic Washer and Cleaning Method ", which removes foreign matter by spraying high pressure cleaning water to a machining part, A process of immersing the processed parts in the detergent by using a "bearing cleaning device" or a lifter device in which foreign matter is removed by spraying air, A process of rotating a part, and a process of taking out a processed part that has been cleaned from a detergent container, have been proposed in Korean Patent Laid-Open No. 1999-0075504 entitled " Automatic cleaning method using ultrasonic waves ".

However, these known cleaning methods are difficult to effectively remove flour, chips, and processing oil remaining on the processed parts, resulting in deteriorated cleaning quality, resulting in poor quality of the finished product, and in the case of subsequent processing, There is a problem that the completeness of the product is lowered.

In addition, there are structural limitations in performing a large number of machined parts continuously, and the cleaning workability is not good, so that there is a problem in achieving an automated process in which cleaning and subsequent machining are linked to each other due to poor connection with subsequent machining.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is therefore an object of the present invention to improve the cleaning quality of machined parts by continuously performing washing, rinsing and drying of the machined parts through the transfer means, The present invention relates to a foreign matter cleaning apparatus for a machining part which improves the productivity of the machining part by improving the machining efficiency of the machining part and improving the productability of the machining part.
