Description

Technical Field

[0001] This utility model belongs to the technical field of liquid filling devices, specifically relating to an automatic liquid filling device for a cutting fluid tank. Background Technology

[0002] Cutting fluid is an industrial liquid used in metal cutting and grinding processes to cool and lubricate cutting tools and workpieces. Cutting fluid is made of a variety of high-performance additives through scientific compounding. Currently, cutting fluid is often added manually. However, manual addition is time-consuming and labor-intensive, and it is easy to fail to add it in time, affecting production and processing, and even damaging machinery.

[0003] Chinese Patent Application No. 2020210406224 discloses an automatic fluid filling device for a cutting fluid tank, including a support member. A mounting plate and a tank are fixedly installed on the right end of the support member. A fluid storage tank is fixedly installed in the middle of the upper part of the mounting plate. A fluid outlet is fixedly connected to the lower end of the fluid storage tank. A fluid filling mechanism is movably inserted into the lower part of the fluid outlet. The left end of the fluid filling mechanism is slidably connected to the middle of the right end of the support member. This automatic fluid filling device for a cutting fluid tank utilizes a floating plate that rises and falls with the fluid level, thereby achieving the lifting and lowering movement of the plug and ultimately automatically opening and closing the drain pipe.

[0004] The above solution saves time and effort while allowing for timely addition of cutting fluid to the tank. However, it can only supply cutting fluid of the same concentration. When dealing with the need for different concentrations of cutting fluid, it is necessary to actively replace the fluid or manually add water to change the concentration, which results in insufficient automation. Utility Model Content

[0005] To solve the above problems, this utility model provides an automatic fluid filling device for a cutting fluid tank, including a machine base, a processing table below the machine base, a cutting fluid tank inside the machine base, a filling pipe at the bottom of the cutting fluid tank, the filling pipe extending downward to the top of the processing table, a level sensor inside the cutting fluid tank, a cutting fluid storage tank and a clean water inlet pipe above the machine base, a cutting fluid outlet pipe below the cutting fluid storage tank, and both the cutting fluid outlet pipe and the clean water inlet pipe communicating with the cutting fluid tank at the bottom. A switch valve is provided at the bottom of both the cutting fluid outlet pipe and the clean water inlet pipe.

[0006] Preferably, a drive motor is provided above the machine base, and a stirring rod is connected to the lower output end of the drive motor. The stirring rod extends into the cutting fluid tank, and stirring blades are provided at the bottom of the stirring rod.

[0007] Preferably, the cutting fluid tank has a funnel-shaped structure.

[0008] Preferably, the cutting fluid tank is transparent, and the front end of the machine tool is hinged with a switch door, which is equipped with a locking mechanism.

[0009] Preferably, a heater is provided on the side of the cutting fluid tank.

[0010] The advantages of this utility model are:

[0011] 1. This solution, by simultaneously installing a cutting fluid storage tank and a clean water inlet pipe, and equipping them with independent on / off valves, can automatically adjust the mixing ratio of cutting fluid and clean water according to processing requirements, thereby precisely controlling the concentration of the cutting fluid. This automated concentration adjustment function greatly improves production efficiency and processing quality.

[0012] 2. The built-in liquid level sensor in this solution can monitor the liquid level in the cutting fluid tank in real time, control the amount and concentration of cutting fluid, reduce unnecessary waste and discharge, and the automated liquid addition also reduces environmental problems such as cutting fluid leakage caused by human factors.

[0013] 3. In this design, when the cutting fluid concentration needs to be adjusted, the stirring rod and blades accelerate the mixing process between water and cutting fluid, making the dilution or concentration process faster and more efficient. This helps reduce adjustment time and improve production efficiency. Attached Figure Description

[0021] like Figure 1-3 As shown, an automatic fluid supply device for a cutting fluid tank 3 includes a machine base 1, a machining table 2 located below the machine base 1, a cutting fluid tank 3 inside the machine base 1, a fluid supply pipe 4 at the bottom of the cutting fluid tank 3, and the fluid supply pipe 4 extending downwards to the top of the machining table 2. The fluid supply pipe 4 is equipped with a corresponding electric valve. The cutting fluid tank 3 is used to supply cutting fluid of a predetermined concentration to the machine being cut on the machining table 2.

[0022] The cutting fluid tank 3 is equipped with a liquid level sensor 5. The built-in liquid level sensor 5 can monitor the liquid level in the cutting fluid tank 3 in real time. Once the liquid level is lower than the preset value, the system will automatically start the liquid adding program and add cutting fluid and clean water in proportion through the cutting fluid output pipe 8 and the clean water input pipe 7 to ensure that the liquid level in the cutting fluid tank 3 is always kept at the optimal state and to ensure that the machining table 2 has a cutting fluid supply at all times.

[0023] A cutting fluid storage tank 6 and a clean water inlet pipe 7 are located above the machine base 1. A cutting fluid outlet pipe 8 is located below the cutting fluid storage tank 6. Both the cutting fluid outlet pipe 8 and the clean water inlet pipe 7 are connected to the cutting fluid tank 3. A switch valve is installed at the bottom of both the cutting fluid outlet pipe 8 and the clean water inlet pipe 7. By simultaneously setting up the cutting fluid storage tank 6 and the clean water inlet pipe 7, and equipping them with independent switch valves, the mixing ratio of cutting fluid and clean water can be automatically adjusted according to processing requirements, thereby precisely controlling the concentration of the cutting fluid. This automated concentration adjustment function greatly improves production efficiency and processing quality.

[0024] A drive motor 9 is mounted above the machine base 1, and a stirring rod 10 is connected to the lower output end of the drive motor 9. The stirring rod 10 extends into the cutting fluid tank 3, and a stirring blade 11 is located at the bottom of the stirring rod 10. The introduction of the stirring rod 10 and the stirring blade 11 ensures that the cutting fluid is thoroughly stirred and mixed in the cutting fluid tank 3. Whether it is newly added cutting fluid, clean water, or existing cutting fluid, the stirring action can quickly achieve a uniform concentration and temperature distribution, avoiding processing problems caused by uneven concentration or temperature differences. When it is necessary to adjust the cutting fluid concentration, the stirring rod 10 and the stirring blade 11 can accelerate the mixing process of clean water and cutting fluid, making the dilution or concentration process faster and more efficient. This helps to reduce adjustment time and improve production efficiency. In addition, some components in the cutting fluid may precipitate or clump over time, affecting the performance. The periodic operation of the stirring rod 10 can prevent this from happening, maintaining the uniformity and fluidity of the cutting fluid.

[0025] In this embodiment, the cutting fluid tank 3 has a funnel-shaped structure. This funnel-shaped design allows for smoother flow of the cutting fluid within the tank, especially during filling and draining, reducing resistance and stagnation and improving the circulation efficiency of the cutting fluid. When mixing cutting fluids of different concentrations or types, the funnel-shaped structure provides better mixing results. When the stirring rod 10 and stirring blades 11 operate within the funnel-shaped tank, they can more effectively mix the cutting fluid evenly, improving mixing efficiency and quality.

[0026] The cutting fluid tank 3 is transparent, and a hinged door 12 is attached to the front of the machine base 1. The door 12 has a locking mechanism 13. The transparent structure of the cutting fluid tank 3 allows the operator to directly observe the state of the cutting fluid, including its level, cleanliness, and the presence of impurities, enabling timely adjustments or cleaning to ensure the quality of the cutting fluid and operational efficiency. The hinged door 12 design makes cleaning, maintenance, and cutting fluid replacement of the cutting fluid tank 3 more convenient. The operator can easily open the door 12 to perform necessary maintenance and upkeep. The locking mechanism 13 can be any type available on the market, including but not limited to magnetic locks and embedded locks.

[0027] A heater 14 is provided on the side of the cutting fluid tank 3. The heater 14 can be an electric heater 14, such as generating heat through heating coils and resistance wires, or any heater 14 available on the market, such as an infrared heater 14. The heater 14 can accurately control the temperature of the cutting fluid in low-temperature winter environments, ensuring that the cutting fluid maintains a stable temperature range during processing, thereby improving the lubricity and cooling performance of the cutting fluid.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
