Description

  The present invention relates to a machined part cleaning apparatus that removes chips and cutting oil adhering to a machined part by cutting of a precision machine tool by underwater cleaning and air cleaning.

  When a metal part is cut with an NC machine tool or the like, chips and cutting oil generated by the process adhere to the surface of the processed part. When the processed parts are transported to the next process by an industrial robot hand or placed in a shipping packaging box, the chips and cutting oil adhering to the processing must be removed as much as possible. In general, an underwater cleaning method using immersion or an air cleaning method using air blow is used. These operations are performed manually or using a fully automatic cleaning apparatus.

  However, the removal means in the air cleaning method by artificial air blow requires an artificial work process in which the operator who operates the NC machine tool, etc., performs manual removal using an air gun. Compressed air is blown in one direction from the outside of the processed part, so if the workpiece has a complicated shape, the entire surface of the processed product cannot be blown evenly unless the handle angle is changed or changed. There was a problem that quality variation was inevitable. There is also a problem that the labor load is large and the working time is not efficient.

  In view of such a problem, there are factories and the like in which industrial robots perform removal means by an air cleaning method. In the case of such large-scale factories that are mass-produced, such facilities are expected to be highly efficient in terms of cost-effectiveness, but such facilities require high introduction costs. There is a problem that it is difficult to incorporate into a factory of scale.

  Therefore, various technical proposals have been made so far to solve the above problems. For example, a gate-shaped frame is formed on the transfer line for transferring a workpiece to be cut through one or more processing stations from the processing station to the next processing station or unloader station. A plurality of cleaning liquid injection nozzles are provided on a surface of the nozzle chamber facing the transfer line, and the nozzle chamber is formed to mix and supply cleaning liquid and compressed air to the chamber. When the workpiece passes through the nozzle chamber, the workpiece passing through the nozzle chamber is washed by mixing and ejecting the cleaning liquid and the compressed air from each spray nozzle. Cleaning method "(see Patent Document 1).

  However, this technology can clean the chips etc. adhering to the work without stopping the work during the work transfer between the stations that transfer the processed work to the next processing station or unloader station. Although we are trying to provide a cleaning device and cleaning method for workpieces that can be washed off with force, the dedicated machine tool and the cleaning device need to be aligned on the transfer line. In general, general-purpose NC machine tools are often equipped with a part insertion slot on the front surface, so cutting in small and medium-sized companies that require a small number of products. It is not suitable for parts cleaning equipment, and since the cleaning method is only air cleaning method, narrow grooves and small Slipped it chips or cutting oil in a further pushed by the injection pressure by the nozzle chamber was achieved, there is a problem that can not be removed.

  Also, a spray water nozzle member having a large number of nozzles is provided in the cleaning chamber, and a drive base is mounted on the lower portion of the cleaning chamber, and a horizontal drive member and a horizontal movable member are fixed on the drive base, and an upper portion is provided. "Washing machine" which can set a work by having a vertical rotation drive member and a work case on the left and right, thereby rotating the work part vertically while spraying by rotating horizontally in the washing chamber (see Patent Document 2) ) Has also been proposed.

  However, when the inner diameter processing part of the machined cleaning part is cleaned with high cleanliness, it is difficult to clean if the cleaning part has a shape in which chips are likely to remain inside the part. In order to solve the problem that it is impossible to wash parts at the same time, the work part is rotated vertically and at the same time, the cleaning chamber is rotated horizontally and spray cleaning is taken, but this cleaning method is only for air cleaning method Therefore, it is possible to remove chips and cutting oil adhering to the workpiece surface, but the chips and cutting oil that have entered complicated grooves and small holes are subject to centrifugal force due to rotation. In addition, there is a problem that cannot be removed only with the spray pressure of the cleaning nozzle.

  Further, in the case of the type in which the parts to be cleaned are placed on the table in the casing, the table or the cleaning pipe is rotated, and the cleaning liquid is sprayed from a plurality of spray nozzles of the cleaning pipe. And a hot water tank and a detergent liquid tank are provided in the casing below the receiver plate, and the receiving plate communicates with the hot water tank and the detergent liquid tank, respectively. An opening / closing valve is provided, the cleaning pipe and each tank are connected by a circulation pipe, a switching valve and a pump are interposed in the circulation pipe, the switching valve is first switched to the hot water tank side, and the first opening / closing valve is opened. "Automatic parts washer" (see Patent Document 3) that cleans hot water, then switches the switching valve to the detergent liquid tank side, closes the first on-off valve and opens the second on-off valve to clean the detergent liquid Proposed) There.

  However, the above-mentioned technology makes it possible to use a detergent for a long period of time, and in order to maintain the effect of the detergent for a long period of time, a large number of workpieces placed on the table are connected from the hot water tank and the detergent liquid tank through the open / close valve. However, since the cleaning method is only the air cleaning method, the chips and cutting oil adhering to the surface of the workpiece can be removed relatively easily. Chips and cutting oil that have entered complicated grooves in narrow grooves and small holes cannot be removed by rotating the table or nozzle spray pressure with hot water and detergent.

  In addition, a large number of openings are formed in the transfer path plate stretched above the trough of the linear vibration feeder, and the nut on which the cutting oil is separated and the chips are to be removed is transferred by vibration. The cleaning oil is ejected from the cleaning oil jetting device disposed immediately above, the cutting oil adhering to the nut is washed away, and the cutting powder is blown off (refer to Patent Document 4). Has been proposed.

  However, the above-mentioned technology is a cleaning device for separating cutting oil adhering to cutting parts such as bolts and nuts, and for automatically and reliably removing deposits such as chips. However, since the means for conveying the machined parts adopts means for conveying by means of vibration by the linear vibration feeder on the transfer path plate stretched above the trough, relatively processed nuts and bolts that are mass-produced It is limited to a machined part that does not require the surface or machining accuracy, and is not suitable as a machined part washing apparatus for washing a precision machined part or the like.

  On the other hand, the removal means in the underwater cleaning method by immersion is to cut the processed parts with an NC machine tool, store the processed parts together in a cleaning basket etc., and immerse them in a cleaning tank equipped with ultrasonic and vibration functions. However, the equipment itself has advanced functions, so it is expensive and requires a large installation space as well as liquid level management and cleaning management of the washing tank. Small and light cutting chips on the surface of the machined part, cutting oil that gets into small grooves and small holes can be washed out and washed, but large and heavy cutting chips cannot be removed. It was a thing. For example, in mass-produced processed parts such as bolts and nuts, the processed parts can be stored together in a cleaning basket etc., but in precision processed parts, it must be transported for each part to avoid surface damage. Therefore, it has the problem that the work efficiency is extremely poor.

  Various proposals have been made to solve the above problems. For example, before machining a part, it is pre-soaked in a cleaning solution and then dried, then the machine is processed with the cleaning agent attached to the part, and then the cleaning agent and dirt adhering to the part are washed away. "Parts cleaning method and cleaning apparatus" (see Patent Document 5).

  However, the above-mentioned technology is intended to provide a cleaning method and a cleaning device having high cleaning efficiency in the cleaning process of metal parts and plastic parts having a machining process. It must be machined in a state where it is dipped in a cleaning solution and then dried, and the cleaning agent is attached to the part, which increases the number of work steps compared to the normal cleaning process, and has narrow grooves and small holes. The relatively heavy swarf that has entered the inside has a problem that it cannot be completely removed by means of applying the spray pressure of the shower nozzle and the cleaning agent to the parts.

  In addition, an operation panel is arranged above the cleaning tank, a peristaltic drive device is accommodated in the operation panel, the cleaning object holder is slidably connected, and the object to be cleaned is freely immersed in the cleaning liquid of the cleaning tank. Like to do. In particular, a “part washing machine” in which a peristaltic drive device is used as an air cylinder and the air is exhausted into the operation panel so that the inside of the operation panel is in a positive pressure state slightly higher than the outside (see Patent Document 6). ) Has been proposed.

  However, the above-mentioned technology is a parts washer that aims to make parts washing machines such as precision parts and electronic parts as small as possible and to be manufactured at low cost, but the washing method is only an underwater washing method, Chips and cutting oil adhering to the surface of the workpiece can be removed relatively easily. However, chips and cutting oil that have entered complicated grooves and small grooves are not suitable for rotating the table or hot water. In addition, there is a problem that cannot be completely removed only by the nozzle spray pressure with the detergent solution.

  As described above, various types of cutting parts cleaning devices that remove chips and cutting oil using a single air cleaner or submersible cleaner have been proposed. There has also been proposed a machined parts cleaning device that combines a machine system and an underwater cleaning system. For example, an apparatus for rotating and cleaning a cleaning object, the cleaning object being held by rotating arms of holding means at both ends in the longitudinal direction, and moved to a cleaning position in the cleaning chamber, and the cleaning liquid is applied to the cleaning object. In-air cleaning is performed by spraying from the cleaning nozzle, the cleaning chamber is filled with the above-described cleaning liquid, the cleaning object is submerged, and underwater cleaning is performed by spraying the cleaning liquid from the cleaning nozzle, and then all cleaning liquid is discharged from the cleaning chamber. “Washing object rotating type underwater cleaning apparatus” (see Patent Document 7).

  However, the above-mentioned technique is intended to quickly and surely remove deposits such as chips and cutting oil generated in cutting work, but the apparatus itself is large and requires a large installation space. It is limited to mass production and large-sized workpiece machining in a company, and general general-purpose NC machine tools are often equipped with a part insertion slot on the front. It was not suitable.

  Further, the cleaning chamber is supported so that the inclination angle of the cleaning chamber can be adjusted, and a cleaning tub for storing and rotating an object to be cleaned is provided therein, and a number of nozzles for injecting cleaning liquid. A discharge port with a valve is provided on the lower surface of the cleaning chamber, and an overflow pipe with an adjustable height is provided. There has been proposed a “part washing machine” (see Patent Document 8) capable of continuously performing air cleaning, liquid cleaning, and air cleaning by opening and closing a valve.

  However, the above-mentioned technology is a parts washer that employs an underwater cleaning method and an air cleaning method that can efficiently and uniformly clean, but relatively processed surfaces and processing such as mass production processing parts such as nuts and bolts. It is limited to a machined part that does not require accuracy, and is not suitable as a machined part cleaning device for precision machined parts.

  Therefore, the present applicant pays attention to combining the underwater cleaning method and the air cleaning method in order to improve the cleaning efficiency and the cleaning effect, and further maintain the accuracy of the parts. Under the idea that it can be cleaned efficiently and effectively by adding rotation and vertical swing, the cutting chips and cutting oil adhering to the processed parts are washed in water by cutting precision machine tools. As a result, a “cutting parts cleaning apparatus” according to the present invention that can be easily removed by air cleaning is proposed.
