Description

Cutting tapping oil direct injection device

The present invention relates to a device for direct injection of cutting tapping oil. More specifically, it is installed in a processing device that performs drilling or tapping, etc., and sprays and supplies cutting tapping oil to the machined area during processing to ensure smooth drilling or tapping. It relates to a cutting tapping oil direct injection device that not only prevents wear of drills and taps, but also prevents residual cutting tapping oil from being generated at the front end of the injection nozzle unit after the injection of cutting tapping oil is completed.

In general, during processing operations such as drilling, milling, cutting, cutting, and tapping, frictional heat is generated at the processing area due to friction between the processing device and the workpiece to be processed.

This frictional heat softens the workpiece, causing the machining surface to become uneven, or is softened by repeated heating of the machining device and causes wear, thereby reducing the lifespan of the machining device.

In order to solve the above problems, a method was used to supply cutting oil and tapping oil to reduce frictional heat generated between the processing object and the processing equipment and to cool the frictional heat generated by processing.

In this method of supplying cutting oil and tapping oil, the worker performing the machining work sprayed the cutting oil and tapping oil directly or poured it into a small container and applied it to the surface of the machining equipment each time.

In this way, if cutting oil and tapping oil are supplied manually, there is a problem in that work efficiency is reduced.

In order to solve this problem, a design for a device for supplying cutting oil and tapping oil was disclosed in Korea Registered Utility Model No. 20-0349111 (cutting oil mist spray device, hereinafter referred to as prior art).

The prior art consists of a main body (10), an oil tank (20), a supply line (30), a spray nozzle (40), and a control device (50) to properly mix oil and air and spray mist, thereby providing high lubrication and In addition, we were able to solve the problem of low efficiency in machining work due to manual work by providing a cutting oil mist spray device that is clean, economical, and stable.

However, in the prior art, there is no structure for sealing the end of the nozzle 40, and even if the injection of cutting oil is terminated by mixing oil and air, the air remains inside the cutting oil and is sealed by the pressure of the remaining air. Cutting oil flows out of the end of the nozzle 40 and residual cutting oil is generated.

This residual cutting oil may fall on the workshop floor over time, contaminating the work environment, or fall on other adjacent devices, causing damage to the device. Not only that, but also the nozzle 40 is completely damaged when the injection of cutting oil is completed. There is a problem that accidents due to slipping may occur as the residual cutting oil generated due to failure to seal properly gets on the worker's hands and other parts of the body, causing the worker's hands and body to slip.

Therefore, when the injection of cutting oil is completed, the nozzle 40 is instantly completely sealed to prevent excess cutting oil from being generated, thereby enabling the injection and supply of cutting oil and tapping oil more stably during machining work. There is a need for development of devices.

Hereinafter, the technical idea of the present invention will be described in more detail using the attached drawings. The attached drawings are only an example to explain the technical idea of the present invention in more detail, so the technical idea of the present invention is not limited to the form of the attached drawings.

Hereinafter, a cutting tapping oil direct injection device according to an example of the present invention will be described in detail with reference to FIGS. 1 to 10.

Figure 1 is a side view showing drilling or tapping by combining a cutting tapping oil direct injection device with a drilling or tapping device according to an embodiment of the present invention.

Referring to FIG. 1, the cutting tapping oil direct injection device according to an example of the present invention is installed in a device that performs drilling or tapping processing and sprays cutting tapping oil on the drill and tap drill during drilling or tapping operations to spray the cutting oil and the processing object. By reducing the frictional heat generated by drill and tap drill bits, drilling or tapping can be performed more easily.

In addition, the silicone stopper 67 is provided to block one end of the oil supply pipe 50 on the inside of the nozzle cover 61, so that when injection of the cutting tapping oil is completed, one end of the oil supply pipe 50 is sealed, thereby allowing the remaining cutting tapping oil to escape. Not only does it keep the working environment comfortable by preventing this from occurring, but it also prevents accidents due to slipping due to cutting oil getting on the hands or bodies of workers by preventing residual cutting and tapping oil from being generated.

This cutting tapping oil direct injection device (1) includes a main body (10), an oil tank (20), a solenoid valve (30), an air injection pipe (40), an oil supply pipe (50), an injection nozzle unit (60), and a timer ( 70), and includes a step switch (80).

Hereinafter, with reference to FIGS. 1 to 10, the components of the cutting tapping oil direct injection device according to an example of the present invention will be described in detail.

Components of the cutting tapping oil direct injection device 1 may be installed in the main body 10.

An oil tank 20, a solenoid valve 30, and a timer 70, which will be described later, may be installed in the main body 10. That is, the main body 10 is configured to install components that operate the cutting tapping oil direct injection device 1 of the present invention.

An oil tank 20 may be coupled to the upper side of the main body 10. The oil tank 20 is a storage space for storing cutting tapping oil used in the cutting tapping oil direct injection device (1).

The oil tank 20 may be made of PET-G material. PET-G material may not be affected by the toxic chemical effects of cutting tapping oil even if the cutting oil is stored for a long period of time.

When using PVC material, which is commonly used in storage containers, etc., as an oil tank (20), if cutting tapping oil is stored for a long period of time, the oil tank (20) is affected by the chemical reaction caused by the toxicity of the tapping oil, causing decomposition and loss of strength. There was a problem of deterioration.

Therefore, in order to solve the above-mentioned problem, the cutting tapping oil direct injection device (1) of the present invention manufactures the oil tank (20) using PET-G material, so that decomposition due to chemical action does not occur and the oil tank (20) ) can be maintained.

Additionally, a leveler 21 may be provided on the outside of the oil tank 20. The leveler 21 can measure the cutting tapping flow rate inside the oil tank.

In other words, when the oil tank 20 is made of PET-G material, the cutting and tapping oil amount inside the oil tank 20 can be checked with the naked eye. However, when the oil tank 20 is made and used with stainless steel material, the cutting and tapping oil amount inside the oil tank 20 can be checked with the naked eye. There is a problem in that it is difficult to check the cutting tapping flow rate inside the oil tank 20. Therefore, since the cutting tapping flow rate can be checked by installing the leveler 21 on the outside of the oil tank 20, the cutting tapping flow rate can be easily checked no matter what material the oil tank 20 is made of.

A solenoid valve 30 may be provided inside the main body 10.

The solenoid valve 30 can be opened and closed by an operation signal and a stop signal. That is, the solenoid valve 30 can be opened or closed by an operation signal and a stop signal to inject or block the air generated from the air compressor into the air injection pipe 40, which will be described later.

An air compressor (not shown) may be connected to one side of the solenoid valve 30. Air generated from the air compressor can be injected into the inside of the oil tank 20 through the solenoid valve 30 and the air injection pipe 40, which will be described later.

Additionally, a timer 70, which will be described later, may be connected to the solenoid valve 30. The solenoid valve 30 may be closed by receiving a stop signal from the timer 70. When the solenoid valve 30 receives a stop signal from the timer 70 and closes, the remaining air remaining inside the oil tank 20 and the air injection pipe 40 can be discharged to the outside. Therefore, after the injection of cutting tapping oil is completed, there is no pressure in the oil tank 20, the air injection pipe 40, and the oil supply pipe 50, which will be described later, to prevent residual cutting tapping oil from being generated in the injection nozzle portion 60. can do.

Additionally, a step switch 80, which will be described later, may be connected to the solenoid valve 30. The solenoid valve 30 may be opened by receiving an operating signal from the step switch 80. The solenoid valve 30 receives an operation signal through manipulation of the step switch 80 and opens to allow air generated from the air compressor to be injected into the air injection pipe 40, which will be described later.

An air injection pipe 40 may be coupled to the other side of the solenoid valve 30. One end of the air injection pipe 40 is coupled to the other side of the solenoid valve 30, and the other end may be located inside the oil tank 20.

The air injection pipe 40 is an air injection path that allows air to be injected into the inside of the oil tank 20 when the solenoid valve 30 is opened by an operation signal. The air injection pipe 40 can use a Teflon hose.

An oil supply pipe 50 may be connected to the oil tank 20. When air is injected into the oil tank 20, the cutting tapping oil inside the oil tank 20 is compressed downward by the pressure of the air and can be supplied to the oil supply pipe 50. That is, the oil supply pipe 50 is preferably coupled to the lower side of the oil tank 20 so that cutting and tapping oil can be smoothly supplied by pneumatic pressure.

Therefore, as cutting tapping oil is supplied to the oil supply pipe 50 by pneumatic pressure, the silicone stopper 67 of the injection nozzle portion 60, which was blocking one end of the oil supply pipe 50, which will be described later, is injected into the oil supply pipe 50. One end of the oil supply pipe 50 is opened by being pushed to one side by the hydraulic pressure of the cutting tapping oil, so that the cutting tapping oil can be sprayed and supplied toward the injection nozzle 63 by air pressure.

This oil supply pipe 50 uses a Teflon hose, and a flexible cable 51 capable of rotating and bending may be provided on the outside of the oil supply pipe 50 in a portion formed outside the main body 10. Therefore, the oil supply pipe 50 is provided with a flexible cable 51 on the outside, so that the injection nozzle part 60, which will be described later, is fixed by rotating and bending in close proximity to the drill or tap drill blade, thereby accurately cutting and tapping the drill or tap drill blade. By allowing the oil to be sprayed, it is possible to prevent wasted cutting tapping oil from being sprayed into the air.

A spray nozzle unit 60 may be formed at one end of the oil supply pipe 50.

The injection nozzle unit 60 can receive cutting tapping oil from the oil supply pipe 50 and spray the cutting tapping oil on the drill or tap drill blade.

The injection nozzle unit 60 includes a nozzle cover 61 formed on one end of the oil supply pipe 50, and is provided on the inside of the nozzle cover 61, wherein the front end is formed with a protruding protrusion, and the other end of the protrusion is formed. A slanted portion inclined at a predetermined angle is formed, and the other end of the slanted portion is formed with a multi-stage cylindrical portion, and the other side of the multi-stage cylindrical portion is formed with a spring coupling portion into which a spring 65 is inserted, and a spray nozzle for spraying cutting tapping oil ( 63), provided between the nozzle cover 61 and the spray nozzle 63, wherein the spray nozzle 63 side is formed with a dish-shaped inclined portion that gradually narrows toward the center, and the central tip of the dish-shaped inclined portion is formed. A spray discharge member 64 having a straight discharge port, a spring 65 on one side of which is fitted into the spring coupling part of the spray nozzle 63, and a spring 65 on one side formed at the rear of the spring 65. A cylindrical spring coupling portion is formed to enable this fitting, and the other side of the spring coupling portion is formed as a hemispherical body to block one end of the oil supply pipe 50, and an auxiliary spring is provided inside the hemispherical body to provide a constant It may include an elastic silicone stopper (67).

The nozzle cover 61 may be provided with a spray nozzle 63, a spray discharge member 64, a spring 65, and a silicone stopper 67 on the inside. The nozzle cover 61 is a structure that can serve as a housing that protects the injection nozzle 63, spring 65, and silicone stopper 67 and allows each component to be formed in a designated position.

A spray nozzle 63 may be formed on one end of the nozzle cover 61. The injection nozzle 63 can be a general nozzle. The injection nozzle 63 can spray cutting tapping oil supplied through the oil supply pipe 50 to the drill or tap drill blade.

A spray discharge member 64 may be provided between the nozzle cover 61 and the spray nozzle 63. The spray/discharge member 64 allows the cutting tapping oil to be sprayed directly, thereby controlling the injection amount of the cutting tapping oil sprayed by the spray nozzle 63.

For example, if 1 mL of cutting tapping oil is sprayed by spraying cutting tapping oil from the spray nozzle 63 without the spray discharge member 64, 2 mL to 3 mL of cutting tapping oil is unintentionally sprayed due to the pressure of the air. There was a problem in that an unnecessary amount of cutting tapping oil was sprayed and the cutting tapping oil was wasted.

Therefore, it is provided between the nozzle cover 61 and the spray nozzle 63, and the spray nozzle 63 side is formed with a dish-shaped inclined portion whose diameter gradually decreases toward the center, and the central portion of the dish-shaped inclined portion is formed. A spray and discharge member 64 having a straight discharge port is formed at the tip, and the cutting tapping oil that has passed through the silicone stopper 67 and the spray nozzle 63 is momentarily spread like fog by the spray and discharge member 64 and then becomes viscous. It is reagglomerated and injected directly onto the blades of drills and tap drills through a straight discharge port formed at the tip of the dish-shaped inclined portion, thereby controlling the injection time of the cutting tapping oil so that the cutting oil is not sprayed in excess of the injection amount set by the air pressure. This ensures that no cutting and tapping oil is wasted.

Additionally, when using a non-viscous fluid other than the viscous cutting tapping oil, it may be sprayed in a mist spray manner by the spray/discharge member 64.

A spring 65 may be fitted and coupled to one side of the injection nozzle 63. The spring 65 is formed to have a certain elasticity and is combined with a silicone plug 67 to be described later on the inside of the nozzle cover 61 so that the silicone plug 67 blocks one end of the oil supply pipe 50 or the oil supply pipe 50. ) and the cutting tapping oil can be supplied to the injection nozzle (63) at a certain interval.

A silicone stopper 67 may be coupled to one side of the spring 65.

The silicone stopper 67 may be provided to block one end of the oil supply pipe 50.

The silicone stopper 67 blocks one end of the oil supply pipe 50 and when the cutting tapping oil supplied to the oil supply pipe 50 is pushed toward the injection nozzle unit 60 by hydraulic pressure, the hydraulic pressure of the cutting tapping oil and the spring 65 are used. Due to elasticity, the silicone plug 67 is pushed toward the injection nozzle 63 and retracted, and at this time, a space is formed between one end of the oil supply pipe 50 and the silicone plug 67, and the cutting oil is cut through the space. It can be supplied by spraying mist toward the front spray nozzle 63.

In addition, the silicone plug 67 dissipates the hydraulic pressure acting on the oil supply pipe 50 by allowing the solenoid valve 30 to discharge the air inside the oil tank 20 and the air injection pipe 40 after the injection of the cutting tapping oil is completed. If so, it can be returned to the original position by the elasticity of the spring 65.

Therefore, the silicone stopper 67 is returned to its original position by the elasticity of the spring 65, sealing one end of the oil supply pipe 50 to prevent cutting tapping oil from leaking from the oil supply pipe 50, and after the injection of cutting oil is completed, the injection nozzle It is possible to prevent residual cutting tapping oil from being generated in the part 60.

Additionally, the silicone stopper 67 may be provided with an auxiliary spring inside. The auxiliary spring allows the silicone stopper 67 to have a certain elasticity, thereby interacting with the above-mentioned spring 65, so that the silicone stopper 67 returns to its original position by elasticity due to the dual elasticity caused by the spring 65 and the auxiliary spring. can be accomplished more easily.

Timer 70 may be connected to solenoid valve 30. The timer 70 is electrically connected to the solenoid valve 30 and can transmit a stop signal to the solenoid valve 30.

The timer 70 may have a time setting value configured to enable time setting.

The timer 70 operates at the same time as the solenoid valve 30 receives an operating signal from the step switch 80, which will be described later, with the time set, and transmits a stop signal to the solenoid valve 30 when the set time has elapsed. You can.

Therefore, the injection amount of cutting tapping oil according to the injection time of the cutting tapping oil can be adjusted by adjusting the opening time of the solenoid valve 30. That is, by decreasing or increasing the time setting value of the timer 70, the opening time of the solenoid valve 30 can be adjusted to adjust the injection amount of cutting tapping oil.

The step switch 80 may be connected to the solenoid valve 30. The step switch 80 is electrically connected to the solenoid valve 30 and can transmit an operating signal to the solenoid valve 30.

The step switch 80 can be operated by a worker performing drilling or tapping processing by touching the step switch 80 with the sole of his or her foot.

That is, the solenoid valve 30 is opened by receiving one operating signal through one operation of the step switch 80, and when the time set in the above-described timer 70 exceeds, it receives a stop signal from the timer 70. It is closed.

Therefore, by operating the step switch 80 once, the cutting tapping oil direct injection device 1 of the present invention can be driven so that the cutting tapping oil is sprayed for a set time.

A coupling member 11 may be coupled to the main body 10. The coupling member 11 can be coupled to the ring-shaped coupling band 13 so that the main body 10 can be coupled to a drilling or tapping device.

Additionally, the fixing part 113 may be formed so that one side is rounded. Accordingly, the rounded portion of the fixing part 113 may come into close contact with the circular pillar shape of the drilling or tapping device.

Cuts 115 cut in the vertical direction may be formed on both sides of the fixing part 113. A ring-shaped coupling band 13 may penetrate and be coupled to the cut portion 115. The coupling band 13 is wrapped around the pillar of the drilling or tapping device, penetrates through the cutout part 115 on one side of the fixing part 113, and then penetrates and couples to the cutout part 115 on the other side, thereby forming the fixing part 113.

It can be combined with .

Hereinafter, with reference to FIGS. 1 to 10, the driving process of the cutting tapping oil direct injection device according to an embodiment of the present invention will be described.
