Description

Technical Field

[0001] This utility model belongs to the field of target material processing technology, and relates to alcohol-based coolant for target material processing, and more particularly to a liquid level display and alarm device for alcohol-based coolant for target material processing. Background Technology

[0002] In the production of target materials, the target dimensions need to be obtained through target machining. Target machining includes finishing, especially when turning with diamond inserts, where the product appearance must achieve a mirror finish and the surface roughness requirements are extremely high. Previously, an oil-water mixture of cutting fluid was used as the coolant, but the turning results were extremely poor, and residual cutting fluid was difficult to remove, which was time-consuming and labor-intensive. Now, an alcohol-based coolant is used, which achieves a mirror finish and meets the surface roughness requirements.

[0003] During actual turning operations, alcohol-based coolant is stored in a coolant storage container, connected to which coolant pipes spray the coolant onto the diamond cutting tools. As turning progresses, the coolant level gradually decreases. Because the coolant storage container is made of stainless steel, operators cannot know the rate of decrease or the remaining volume. If the coolant level becomes too low, it can cause the diamond cutting tool to dry-cut, significantly impacting both the tool and the target material. Currently, the coolant level in the storage container needs to be manually checked daily to determine if it is sufficient for a day's production and to identify any potential problems.

[0004] Therefore, it is necessary to develop a level display and alarm device for alcohol-based coolant used in target processing to solve the problem that operators cannot effectively observe the remaining amount of alcohol-based coolant during target processing. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a liquid level display and alarm device for alcohol-based coolant used in target material processing. By monitoring the position of a magnetic float in the vertical connecting pipe, the remaining amount of alcohol-based coolant in the coolant storage container can be monitored at all times. When the liquid level drops to the alarm level, an alarm is triggered, reminding the operator to add alcohol-based coolant in time. This ensures that there is sufficient alcohol-based coolant during target material processing to prevent the machine from drying out, thus guaranteeing product quality and processing efficiency.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A liquid level display and alarm device for an alcohol-based coolant used in target processing includes: a coolant storage container with a cap on top; a transparent vertical connecting pipe disposed on the outer side of the coolant storage container; the upper part of the vertical connecting pipe is connected to the liquid level of the coolant storage container; and the lower part of the vertical connecting pipe is connected to the bottom of the coolant storage container, such that the coolant storage container and the vertical connecting pipe form a communicating vessel and both have the same liquid level.

[0008] A measuring guide rod is fixedly installed inside the vertical connecting pipe; a magnetic float is fitted on the measuring guide rod and floats up and down along the measuring guide rod with the liquid level change to realize liquid level display;

[0009] The measuring guide rod contains a printed circuit board with arranged sensing circuits. The printed circuit board with arranged sensing circuits is a combination circuit of a precision resistor R and a reed switch K. The printed circuit board with arranged sensing circuits is electrically connected to the alarm, converting the alarm liquid level signal into a resistance signal, and then triggering the alarm through the alarm.

[0010] As is well known to those skilled in the art, due to the safety hazards caused by the volatility of alcohol-based coolants, coolant storage containers are often made of stainless steel and have lids on top, making it impossible for operators to know the remaining amount of alcohol-based coolant in the storage container. In this invention, based on the principle of communicating vessels, a transparent vertical connecting pipe is installed on the outer side of the coolant storage container, ensuring that both have the same liquid level. The position of a magnetic float inside the vertical connecting pipe allows for real-time monitoring of the remaining amount of alcohol-based coolant in the storage container. When the liquid level drops to the alarm level, an alarm is triggered, reminding the operator to add alcohol-based coolant in time. This ensures sufficient alcohol-based coolant is available during target processing to prevent dry machining, thus guaranteeing product quality and processing efficiency. The device described in this invention not only reduces the workload of operators but also prevents dry machining due to insufficient alcohol-based coolant, resulting in stable surface quality, high efficiency, and a simple and practical structure.

[0011] As a preferred embodiment of this invention, the alarm includes a buzzer and / or a flashing light for alarm alerts.

[0012] As a preferred technical solution of this utility model, the printed circuit board with the arranged sensing circuit is electrically connected to the level gauge for digital display of the level of the alcohol-based coolant used for target material processing.

[0014] As a preferred technical solution of this utility model, the control chip is an integrated circuit LM3914.

[0015] As a preferred technical solution of this utility model, a plurality of LED planar tubes for indicating the liquid level are arranged in parallel inside the liquid level gauge. The plurality of LED planar tubes are arranged in a columnar shape and are electrically connected to the control chip shown.

[0016] As a preferred technical solution of this utility model, the number of LED planar tubes is 10, which are used to indicate the liquid level height range of 0 to 100%. When the liquid level is full, all 10 LED planar tubes with the 0 to 100% scale are lit.

[0017] As a preferred technical solution of this utility model, the liquid level gauge is provided with a liquid level gauge scale display panel sticker, which is glued to the surface of the liquid level gauge housing. Furthermore, the liquid level gauge has a rectangular structure, and the display surface of the liquid level gauge is a brown organic glass light-transmitting display.

[0018] As a preferred technical solution of this utility model, the magnetic float is a hollow sphere, and the magnetic float has a through hole in the radial direction for passing through the measuring guide rod. The magnetic float is equipped with a ring magnet in the radial direction inside, and the ring magnet is coaxial with the through hole.

[0019] As a preferred technical solution of this utility model, the measuring guide rod is a stainless steel measuring guide rod.

[0020] It should be noted that the liquid level gauge housing is provided with mounting holes; the main body of the vertical connecting pipe is made of transparent material, but the rest is made of stainless steel, and a mounting flange is provided at the top. The upper end of the measuring guide rod is seamlessly welded to the mounting flange, and the mounting flange is provided with flange mounting holes; the printed circuit board inside the measuring guide rod, which arranges the sensing circuit, is electrically connected to the alarm and the liquid level gauge independently through a junction box, so that the alarm liquid level of the alarm can be adjusted according to actual needs, while the liquid level gauge is simply used for digital display of the liquid level of the alcohol-based coolant used for target material processing.

[0030] Example 1

[0031] This embodiment provides a liquid level display and alarm device for alcohol-based coolant used in target material processing, such as... Figure 1 As shown, it includes: a coolant storage container 1 with a lid on top, and a transparent vertical connecting pipe 2 provided on the outer side of the coolant storage container 1. The upper part of the vertical connecting pipe 2 is connected to the coolant level of the coolant storage container 1, and the lower part of the vertical connecting pipe 2 is connected to the bottom of the coolant storage container 1, so that the coolant storage container 1 and the vertical connecting pipe 2 form a communicating vessel and have the same liquid level.

[0032] A measuring guide rod 3 is fixedly installed inside the vertical connecting pipe 2; a magnetic float 4 is fitted on the measuring guide rod 3 and floats up and down along the measuring guide rod 3 with the liquid level change to realize liquid level display;

[0033] The measuring guide rod 3 contains a printed circuit board with arranged sensing circuits. The printed circuit board with arranged sensing circuits is a combination circuit of a precision resistor R and a reed switch K. The printed circuit board with arranged sensing circuits is electrically connected to an alarm, converting the alarm liquid level signal into a resistance signal, and then triggering an alarm through the alarm 5. The printed circuit board with arranged sensing circuits is also electrically connected to a liquid level gauge 6, which is used to digitally display the liquid level of the alcohol-based coolant used for target material processing.

[0034] The alarm 5 includes a buzzer and a red flashing light connected in series for alarm reminder. The series circuit is also equipped with a reed switch and a battery. Under normal circumstances, the battery is in the open state. When the magnetic float gradually descends along the measuring guide rod, and the liquid level drops to the alarm level, the magnetic float drives the reed switch to close, so that the buzzer and red flashing light in the circuit are powered on and start the alarm.

[0035] The liquid level gauge 6 contains a control chip, which is an integrated circuit LM3914; for example Figure 2As shown, the liquid level gauge has 10 parallel LED planar tubes arranged in a columnar pattern inside, which are electrically connected to the control chip shown. The 10 LED planar tubes indicate the liquid level range of 0-100%, and all 10 LED planar tubes on the 0-100% scale are lit when the liquid level is full. A liquid level gauge scale display panel sticker is attached to the surface of the liquid level gauge 6 housing; correspondingly, as... Figure 3 As shown, the printed circuit board with the sensor circuit is a combination circuit of 10 precision resistors R and 10 reed switches K. As the liquid level drops, the magnetic float gradually descends along the measuring guide rod, driving the reed switches K to gradually close from top to bottom. This reduces the resistance in the circuit, i.e., the resistance value decreases, causing the sensor to output different resistance values. The sensor transmits the changing resistance signal to the meter head, which converts the resistance change signal into a voltage change signal through a resistor voltage divider inside the meter head. The liquid level is then displayed intuitively through 10 LED flat tubes.

[0036] The magnetic float 4 is a hollow sphere. The magnetic float 4 has a through hole in the radial direction for passing through the measuring guide rod 3. The magnetic float 4 is equipped with a ring magnet in the radial direction inside. The ring magnet is coaxial with the through hole.

[0037] The measuring guide rod 3 is made of stainless steel.

[0038] In practical applications, operators can visually check the remaining amount of alcohol-based coolant in the coolant storage container by observing the scale display on the level gauge. When the level drops to the alarm level of 20%, an alarm will be triggered by the buzzer and red flashing light of the alarm device, reminding the operator to add alcohol-based coolant in time. This ensures that there is enough alcohol-based coolant during target processing to prevent the machine from drying out, thus guaranteeing product quality and processing efficiency.

[0039] Example 2

[0040] This embodiment provides a liquid level display and alarm device for an alcohol-based coolant used in target processing, comprising: a coolant storage container with a top cover, a transparent vertical connecting pipe disposed on the outer side of the coolant storage container, the upper part of the vertical connecting pipe being connected to the liquid level of the coolant storage container, and the lower part of the vertical connecting pipe being connected to the bottom of the coolant storage container, such that the coolant storage container and the vertical connecting pipe constitute a communicating vessel, and both have the same liquid level;

[0041] A measuring guide rod is fixedly installed inside the vertical connecting pipe; a magnetic float is fitted on the measuring guide rod and floats up and down along the measuring guide rod with the liquid level change to realize liquid level display;

[0042] The measuring guide rod contains a printed circuit board with a sensor circuit. The printed circuit board with the sensor circuit is a combination circuit of a precision resistor R and a reed switch K. The printed circuit board with the sensor circuit is electrically connected to the alarm, converting the alarm liquid level signal into a resistance signal, and then triggering the alarm through the alarm.

[0043] The alarm 5 includes a buzzer and a red flashing light connected in series for alarm reminder. The series circuit is also equipped with a reed switch and a battery. Under normal circumstances, the battery is in the open state. When the magnetic float gradually descends along the measuring guide rod, and the liquid level drops to the alarm level, the magnetic float drives the reed switch to close, so that the buzzer and red flashing light in the circuit are powered on and start the alarm.

[0044] The magnetic float 4 is a hollow sphere. The magnetic float 4 has a through hole in the radial direction for passing through the measuring guide rod 3. The magnetic float 4 is equipped with a ring magnet in the radial direction inside. The ring magnet is coaxial with the through hole.

[0045] The measuring guide rod 3 is made of stainless steel.

[0046] In practical applications, the alarm's buzzer and red flashing light can remind operators to add alcohol-based coolant in time, ensuring sufficient coolant is available during target processing to prevent the machine from drying out and guaranteeing product quality and processing efficiency. However, because the level gauge is omitted, operators cannot accurately determine the remaining amount of alcohol-based coolant in the coolant storage container, making it difficult to know the rate at which the alcohol-based coolant is decreasing.

[0047] In summary, this invention provides a liquid level display and alarm device for alcohol-based coolant used in target material processing. Based on the principle of communicating vessels, a transparent vertical connecting pipe is installed on the outer side of the coolant storage container, ensuring that both have the same liquid level. The position of a magnetic float inside the vertical connecting pipe allows for real-time monitoring of the remaining amount of alcohol-based coolant in the storage container. When the liquid level drops to the alarm level, an alarm is triggered, reminding the operator to add alcohol-based coolant in time. This ensures sufficient alcohol-based coolant is available during target material processing to prevent dry machining, thus guaranteeing product quality and processing efficiency. The device described in this invention not only reduces the workload of operators but also prevents dry machining due to insufficient alcohol-based coolant, resulting in stable surface quality, high efficiency, and a simple and practical structure.

Those skilled in the art should understand that any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model fall within the protection and disclosure scope of the present utility model.
