Description

MCT device equipped with an air filtration module

The present invention relates to an MCT device equipped with an air filtration module, and more specifically, fine metal dust generated during cutting of a workpiece is primarily collected by cutting oil stored in a water tank, and is then output through an air output nozzle. This relates to an MCT device equipped with an air filtration module that can cleanly collect fine dust while polluted air around the cutting area is sucked in by the air current absorbed into the air suction nozzle.

Typically, a machining center is a machine tool that performs a wide range of processing that can be performed on lathes, milling, drilling, boring machines, etc., and is equipped with tools that rotate with a main axis to process workpieces seated on a table.

In addition, chips generated during processing of workpieces are collected on a chip conveyor, but fine metal chips scatter in the air, contaminating the surrounding environment, and are inhaled into the human body of workers, causing adverse effects.

Accordingly, in the previously disclosed registered patent No. 10-2175181, a processing chamber unit for processing an input workpiece using either a tool that moves in the vertical or horizontal direction or a tool that rotates; In the MCT processing device, which includes a clamping jig including a processing jig portion for aligning and fixing the workpiece processed by the tool on the bed, dust generated during processing of the workpiece inside the processing chamber is sucked to remove dust and air. It further includes a dust collection exhaust unit for classifying and discharging the dust, wherein the dust collection exhaust unit includes an exhaust port formed through one side of the chamber enclosure to discharge dust generated inside the chamber enclosure; A collection net formed toward the exhaust port inside the chamber enclosure to collect coarse dust among the dust moving toward the exhaust port; A dust collector formed toward the exhaust port outside the chamber enclosure to collect dust moving through the collection net using electricity and water; A dust filter formed on one side of the dust collector to filter out dust with a particle size of 03㎛ ~ 1㎛ in the air that is filtered and moved through the dust collector; A fine dust filter formed on one side of the dust filter to filter fine dust in the air that is filtered and moved through the dust filter; An air discharge motor connected to one side of the fine filter by an air discharge pipe to move dust inside the chamber housing to the outside; an air discharge pipe formed to be connected between the air discharge motor and the fine filter, and formed on one side of the air discharge motor to discharge purified air moved through the air discharge motor to the outside; A foreign matter discharge pipe formed at the bottom of the dust collector to discharge foreign substances discharged through the dust collector to the outside; A filtering pipe formed at the center of the foreign matter discharge pipe to filter out scrap from the foreign matter moving along the foreign matter discharge pipe; A drain pipe formed on one side of the foreign matter discharge pipe to discharge waste water filtered by foreign substances; A technology including a pollution sensor formed on one side of the air discharge pipe has been previously proposed to measure the pollution level of dust-filtered air.

However, the prior art is intended to collect dust generated during processing and classify and discharge foreign substances and air. However, since the exhaust port is formed on one side of the chamber enclosure and is provided to suck the air inside the chamber enclosure, it flows in all directions within the chamber enclosure. The problem was that flying dust could not be effectively sucked in, and most of the dust was adsorbed on the workpiece, deteriorating processing quality and seriously contaminating the surrounding air.

The present invention relates to an MCT device equipped with an air filtration module, in which fine metal dust generated during cutting workpieces is primarily collected by cutting oil stored in a water tank, and is then output through an air output nozzle to inhale air. A jig (100), a water tank (200), an air output nozzle (300), an air suction nozzle (400) are used to cleanly collect fine dust while contaminated air around the cutting area is sucked in by the air current absorbed into the nozzle side. The main components include an air filtration module (500) and a circulation fan (600).

The jig 100 according to the present invention is installed on the table 110 of the MCT device to seat and secure the workpiece 1.

The jig 100 is provided to flexibly clamp the shape of the vise or workpiece 1.

In addition, the water tank 200 according to the present invention is installed on the table 110 to surround the jig 100, the top is open to accommodate cutting oil, and a drain pipe 210 for water level adjustment is provided at the upper end. is formed

In Figure 2, the water tank 200 is formed of an expandable pipe, and is provided to be adjusted to expand and contract in the longitudinal direction by a lifting bar 220 that is linearly transported by a driving unit.

At this time, the lifting rod 220 is provided to adjust its stretchable length in connection with the cutting coordinate value input to the control unit to numerically control the cutting tool of the MCT device in the Z-axis direction.

In addition, the water tank 200 is adjusted to expand and contract by the lifting rod 220, and the drain pipe 210 is positioned higher compared to the height of the point where the workpiece 1 is cut, so that the point where the workpiece 1 is cut is As cutting processing is performed while immersed in cutting oil contained in the water tank 200, fine metal chips scattered during cutting are captured in the cutting oil, thereby quickly cooling surrounding air contamination and cutting heat to improve cutting efficiency.

In addition, the air output nozzle 300 according to the present invention is installed on the table 110 and sprays air in the horizontal direction toward the workpiece 1.

The air output nozzle 300 is connected to a circulation fan 600, which will be described later, through an expansion pipe, and is provided to flexibly move along with the table 110 during the cutting process.

In addition, the air suction nozzle 400 according to the present invention is installed on the table 110 to face the air output nozzle 300, and is provided to suction air sprayed through the air output nozzle 300.

The air suction nozzle 400 is connected to the air filtration module 500, which will be described later, through an expansion pipe, and is provided to flexibly move along with the table 110 during the cutting process.

In this way, fine metal dust (chips) generated during cutting the workpiece 1 is primarily collected in the cutting oil stored in the water tank 200, and is output through the air output nozzle 300 to inhale air. There is an advantage that fine dust is cleaned cleanly as contaminated air around the cutting area is sucked in by the air current absorbed into the nozzle 400.

Additionally, the air filtration module 500 according to the present invention is provided to filter contaminated air sucked through the air suction nozzle 400.

In addition, the circulation fan 600 according to the present invention is connected to the air filtration module 500 to suck in filtered air and circulate it to the air output nozzle 300.

In FIG. 3, the air filtration module 500 has an intake port 511 formed at an eccentric position on the outer circumferential surface to be connected to the air intake nozzle 400, and a foreign material discharge port 512 is formed as the diameter decreases toward the bottom, A cyclone dust collector 510 is formed with an exhaust port 513 in the upper center that discharges primary filtered air from which foreign substances have been centrifuged, and is connected to the exhaust port 513 of the cyclone dust collector 510 to perform secondary filtration of the primary filtered air. It includes a filter module 520 provided to do so.

Here, the cyclone dust collector 510 is a device that collects various types of dust using mechanical centrifugal force. The airflow enters the cyclone, forms a rotational flow, and goes downwards. The rotational flow generates dust by the centrifugal force of the dust. It is separated from this airflow, and the separated airflow changes direction at the bottom and rises to the exhaust port 513.

At this time, the filter module 520 is connected to the exhaust port 513 of the cyclone dust collector 510 and includes a filtration tank 522 with an inlet port 521 formed at the bottom to allow primary filtration air to be introduced, and a filtration tank ( 522) It is installed laterally inside, and one end extends outside the filtration tank 522 through the connection pipe 523, and is inserted into the perforated pipe 524 connected to the circulation fan 600, and the perforated pipe 524. It includes a rotating filter 525 that is rotated by the driving unit and performs secondary filtering of the primary filtered air.

Here, the rotating filter 525 is supported by a bearing installed on the outer peripheral surface of the perforated pipe 524 to minimize frictional resistance when rotating.

As the rotary filter 525 rotates in this way, the outer peripheral surface of the rotary filter 525 is exposed to the inlet port 521 area in a 360° direction, so there is an advantage in that the entire area of the rotary filter 525 can be effectively used. .

In Figure 4, the rotating filter 525 is provided to be washed with water by the water washing module 700.

The washing module 700 is connected to the first three-way valve 711 installed on the connection pipe 523 and removes foreign substances from the water intake pipe 710 and the cyclone dust collector 510 for injecting washing water into the perforated pipe 524. It is connected to the second three-way valve 721 installed at the outlet 512 and includes a water outlet pipe 720 that discharges contaminated water discharged to the cyclone dust collector 510 via the rotary filter 525.

Looking at the operating state of the flushing module 700, when the flushing mode is executed by the flushing module 700, the foreign matter outlet 512 and the water outlet pipe 720 are communicated by the operation of the second three-way valve 721. , the perforated pipe 524 is in communication with the water intake pipe 710 by operating the first three-way valve 711, and the rotary filter 525 is rotated at 10 to 60 rpm by the driving unit.

And when the washing water is introduced through the water intake pipe 710, the washing water passes from the inside to the outside of the rotary filter 525 via the perforated pipe 524, and the foreign substances collected in the rotary filter 525 are separated, causing a cyclone. It passes through the inside of the dust collector 510 and is discharged through the water outlet pipe 720.

Thereafter, after a set time has elapsed based on the time when the washing water is introduced through the water intake pipe 710, the water intake pipe 710 is closed by operating the first three-way valve 711, and the rotary filter 525 It is equipped to dehydrate the remaining washing water while rotating at 100 to 500 rpm by the driving part.

In this way, since foreign substances collected in the rotating filter 525 by the washing module 700 are automatically cleaned, there is an advantage that filtration performance through the rotating filter 525 is improved even when used continuously for a long period of time.

In Figure 5, a diffusion module 800 is installed in the exhaust port 513 to disperse and output the washing water to the inner peripheral surface of the cyclone dust collector 510.

The diffusion module 800 is installed to close the lower end of the exhaust port 513 and includes a stopper plate 810 on which a plurality of passages 811 are formed, and a guide rod 821 installed in the center of the stopper plate 810. A check disk 820 that moves in the up and down direction inside the exhaust port 513 to open and close the flow path 811, and blocks the inflow of air while allowing discharge of air inside the cyclone dust collector 510 through the flow path 811, A distribution water outlet pipe 830 is installed radially on the exhaust port 513 corresponding to the inner upper area of the cyclone dust collector 510 and is provided to communicate with the exhaust port 513, and is inserted and installed on the inner peripheral surface of the exhaust port 513, and a connecting stand. It is connected to the check disk 820 by 841 and includes an inner ring 840 that opens and closes the distribution water discharge pipe 830 while moving in the vertical direction in connection with the check disk 820.

Looking at the operating state of the diffusion module 800, when the air inside the cyclone dust collector 510 moves toward the filter module 520 through the exhaust port 513 due to the operation of the circulation fan 600, the check disk 820 moves upward. As the inner ring 840 moves upward and operates to open the flow path 811, the distribution water discharge pipe 830 is closed. When the cleaning mode is executed by the flushing module 700, the check disk 820 is opened. While being transported downward to close the flow path 811, the inner ring 840 is transported downward to open the distribution water pipe 830.

In addition, when the washing water discharged to the cyclone dust collector 510 via the filter module 520 reaches a predetermined level while stored in the exhaust port 513, it is output in a 360° direction through the distribution water discharge pipe 830 to create a cyclone. Since the dust collector 510 is equipped to clean the inner peripheral surface, there is an advantage that foreign substances remaining on the inner wall of the cyclone dust collector 510 can be easily removed without disassembling the cyclone dust collector 510.

As described above, the most preferred embodiments of the present invention have been described in the detailed description of the present invention, but various modifications may be made without departing from the technical scope of the present invention. Therefore, the scope of protection of the present invention should not be limited to the above embodiments, but should be recognized to the technologies in the patent claims described later and to equivalent technical means from these technologies.
