Description

Technical Field

[0001] This utility model relates to the field of high-pressure cutting fluid delivery technology, and in particular to a water tank type high-pressure cutting fluid delivery system. Background Technology

[0002] In the field of machining, especially during the operation of CNC machine tools and machining centers, cutting fluid is widely used for cooling, lubricating, cleaning, and chip removal of tools and workpieces. To achieve good cooling and flushing effects, high-pressure conveyors are usually used to deliver the cutting fluid to the cutting area at high pressure and flow rate.

[0003] Existing high-pressure cutting fluid conveyors typically consist of a separate power unit and a separate cutting fluid tank. The power unit is connected to the independently located tank via suction and return lines. Cutting fluid used in the machining area is initially treated by a recovery system and then returned to the independent tank. Subsequently, the high-pressure conveyor draws cutting fluid from the tank, pressurizes it, and delivers it to the machining point.

[0004] However, this existing technical solution of separating the high-pressure conveyor and the water tank has many inherent drawbacks: Large space occupation: Independent water tanks and high-pressure conveyors require valuable space on the workshop floor or next to the equipment. For compact modern production workshops or small processing units, this layout greatly reduces space utilization and increases the floor space occupied by the equipment.

[0005] The piping system is complex, resulting in high energy loss and leakage risks: Because the water tank is separate from the main unit, long suction and return pipes are required. These lengthy pipes not only increase piping costs and installation complexity but also lead to pressure loss along the pipes, reducing system efficiency. Furthermore, more pipe connection points mean a higher risk of leakage, contaminating the working environment and wasting cutting fluid. Utility Model Content

[0006] Based on the above, the purpose of this utility model is to provide a water tank type high-pressure cutting fluid delivery system, which reduces the overall footprint of the equipment and simplifies the pipeline.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: This utility model provides a water tank type high-pressure cutting fluid delivery system, including: The chassis includes a separated sealed water tank and a mounting box, the sealed water tank being located below the mounting box; A high-pressure delivery pump is installed inside the mounting box. It includes a delivery pump fluid inlet pipe and a delivery pump fluid outlet pipe. The fluid outlet pipe is connected to an external machine tool. A water pump is installed inside the sealed water tank. The water pump is connected to the delivery pump fluid inlet pipe through a first water pump pipe. The first water pump pipe passes through the top of the sealed water tank. A first water delivery pipe is also installed inside the sealed water tank. The first water delivery pipe passes through the top of the sealed water tank. A liquid level monitoring unit is installed inside the mounting box, and includes a monitoring float located inside the sealed water tank. A filtration unit is located on the top of the mounting box and includes a filter fluid inlet pipe and a filter fluid outlet pipe. The filter fluid outlet pipe is connected to the first water supply pipe. A second water supply pipe is also provided on the side of the mounting box. The second water supply pipe passes through the inside and outside of the mounting box and is connected to the filter fluid inlet pipe.

[0008] Preferably, a drain pipe is provided at the bottom of the sealed water tank.

[0009] Preferably, the liquid level monitoring unit further includes a monitoring mounting plate, which is disposed at the bottom of the mounting box.

The monitoring hollow tube has a hollow structure, and a floating rod is disposed inside the monitoring hollow tube. A sensing module is disposed at the top of the floating rod, and the bottom of the floating rod extends into the sealed water tank and connects to the monitoring float. When the monitoring float moves up and down with the liquid level change, the floating rod moves up and down accordingly. A first proximity switch is disposed at the top of the stabilizing rod, a second proximity switch is disposed at the bottom of the stabilizing rod, and a third proximity switch is disposed near the bottom of the stabilizing rod.

[0010] Preferably, the bottom of the monitoring mounting plate is also provided with a limiting cover, the limiting cover having a plurality of limiting strip holes, the limiting cover extending into the sealed water tank, and the float ball located inside the limiting cover.

[0011] Preferably, the rear side of the mounting box is provided with heat dissipation holes.

[0012] Preferably, the mounting box is provided with doors on both sides.

[0013] Preferably, the filtration unit further includes a filter barrel, which is a hollow structure.

[0015] Preferably, the top of the mounting box is provided with a filter mounting groove, and the outer wall of the filter barrel is provided with an annular fixing plate.

[0016] The beneficial effects of this utility model are as follows: (1) By directly integrating the sealed water tank inside the chassis and located at the bottom of the mounting box, the power unit and liquid storage of the high-pressure conveying system are integrated. This structure eliminates the need for a separate external water tank, and combines the footprint of the traditional "main unit + water tank" two separate devices into a compact whole, reducing the overall footprint of the equipment.

[0017] (2) Since the sealed water tank and the high-pressure delivery pump are located in the same chassis, all fluid connections (such as the first pumping pipe, the first delivery pipe, etc.) are internal short-distance connections, eliminating the lengthy external pipelines in the prior art. This not only reduces pipeline costs and installation complexity, but more importantly, it reduces pressure loss along the pipeline and improves the system's working efficiency.

[0020] (5) The filter section is located on the top of the installation box. After use, the cutting fluid can enter the filter section through the second water supply pipe. After being filtered by the filter element, the clean cutting fluid flows back to the sealed water tank through the first water supply pipe, forming a complete internal treatment cycle. This ensures that the cutting fluid supplied to the high-pressure pump is always clean. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] like Figures 1 to 5As shown, this utility model embodiment provides a water tank type high-pressure cutting fluid delivery system, including: a chassis 1, which includes a sealed water tank 11 and a mounting box 12 separated from each other, the sealed water tank 11 being located below the mounting box 12, and the sealed water tank 11 and the mounting box 12 being separated by a partition plate 121; a high-pressure delivery pump 2, disposed inside the mounting box 12 and located above the partition plate 121, which includes a delivery pump fluid inlet pipe 21 and a delivery pump fluid outlet pipe 22, the fluid outlet pipe being connected to an external machine tool; a water pump 111 disposed inside the sealed water tank 11, the water pump 111 being connected to the delivery pump fluid inlet pipe 21 through a first water pump pipe 112, the first water pump pipe 112 passing through the top of the sealed water tank 11, the first water pump pipe 112 being fixed on the partition plate 121; and a high-pressure delivery pump 2 disposed inside the sealed water tank 11. A first water supply pipe 113 is provided, which passes through the top of the sealed water tank 11 and is fixed to the partition plate 121; a liquid level monitoring unit 3 is provided inside the mounting box 12, which includes a monitoring float 31 located inside the sealed water tank 11, and is used to monitor the liquid level in the sealed water tank 11; a filtration unit 4 is provided at the top of the mounting box 12, which is used to filter the cutting fluid supplied to the sealed water tank 11, and includes a filter fluid inlet pipe 41 and a filter fluid outlet pipe 42, which is connected to the first water supply pipe 113; a second water supply pipe 43 is also provided on the side of the mounting box 12, which passes through the inside and outside of the mounting box 12 and is connected to the filter fluid inlet pipe 41.

[0029] In this embodiment of the invention, the working principle of the water tank type high-pressure cutting fluid delivery system is as follows: Cutting fluid is delivered externally to the filtration section 4 via a second delivery pipe and a filter fluid input pipe 41. After filtration in the filtration section 4, the cutting fluid is delivered to a sealed water tank 11 for storage. The cutting fluid in the sealed water tank 11 is driven by a water pump 111 and connected to the high-pressure delivery pump 2's delivery pump fluid input pipe 21 via a first water pump pipe 112. The high-pressure delivery pump 2 then delivers the cutting fluid to the machine tool. The cutting fluid used by the machine tool can be returned via a second water pipe 43 for reuse. In this embodiment of the invention, by directly integrating the sealed water tank 11 inside the chassis 1 and located at the bottom of the mounting box 12, the power unit and liquid storage of the high-pressure delivery system are integrated. This structure eliminates the need for a separate external water tank, merging the footprint of the traditional "main unit + water tank" two independent devices into a compact whole, reducing the overall footprint of the equipment. Since the sealed water tank 11 and the high-pressure delivery pump 2 are located within the same casing 1, all fluid connections (such as the first pumping pipe 112, the first delivery pipe 113, etc.) are internal short-distance connections, eliminating the lengthy external pipelines found in existing technologies. This not only reduces pipeline costs and installation complexity, but more importantly, it reduces pressure loss along the pipeline and improves system efficiency.

[0030] In some embodiments, such as Figure 2 and 3 As shown, a drain pipe 114 is provided at the bottom of the sealed water tank 11. Specifically, when it is necessary to drain the cutting fluid inside the sealed water tank 11, it can be discharged through the drain pipe 114.

[0031] In some embodiments, such as Figure 3 and 4As shown, the liquid level monitoring unit 3 also includes a monitoring mounting plate 32, which is disposed at the bottom of the mounting box 12 and mounted on the partition plate 121. It should be noted that the partition plate 121 has a slot corresponding to the monitoring mounting plate. A monitoring fixing base 321 is provided on the monitoring mounting plate 32, and a monitoring hollow tube 322 and a monitoring stabilizing rod 323 are provided on the monitoring fixing base 321. A monitoring fixing top plate 324 is connected to the top of the monitoring hollow tube and the monitoring stabilizing rod 323. The monitoring hollow tube has a hollow structure, and a floating rod 325 is installed inside the monitoring hollow tube. A sensing module 326 is installed at the top of the floating rod 325, and the bottom of the floating rod 325 extends into the sealed water tank 11 and connects to the monitoring float 31. When the monitoring float 31 moves up and down with the liquid level, the floating rod 325 moves up and down accordingly. A first proximity switch 327 is installed at the top of the stabilizing rod, a second proximity switch 328 is installed at the bottom of the stabilizing rod, and a third proximity switch 329 is installed near the bottom of the stabilizing rod. Specifically, in this embodiment, the float moves up and down with the liquid level, which in turn moves the sensing module 326 up and down. When the sensing module 326 is located at the first proximity switch 327, it indicates that the liquid level in the sealed water tank 11 has reached the top, at which point the automatic stop of the supply of cutting fluid to the sealed water tank 11 is triggered. When the sensing module 326 is located at the third proximity switch 329, it indicates that the liquid level in the sealed water tank 11 has reached the warning line, at which point it will trigger the supply of cutting fluid into the sealed water tank 11. When the sensing module 326 is located at the second proximity switch 328, it indicates that there is almost no cutting fluid in the sealed water tank 11, at which point it will trigger a shutdown. In this embodiment of the invention, the built-in liquid level monitoring unit 3, through the cooperation of the float ball 31, the floating rod 325 and multiple proximity switches, can monitor the liquid level status in the water tank in real time and accurately, realizing high and low liquid level alarms or automatic control.

[0032] In some embodiments, such as Figure 3 and 4 As shown, a limiting cover 33 is also provided at the bottom of the monitoring mounting plate 32. The limiting cover 33 has several limiting strip holes 331. The limiting cover 33 extends into the sealed water tank 11, and the float is located inside the limiting cover 33. Specifically, by setting the limiting cover 33, the float is confined within the limiting cover 33 and can only move up and down, ensuring that the float moves vertically and will not reduce the service life of the float rod 325 due to left and right swinging.

[0033] In some embodiments, such as Figure 2 As shown, in order to dissipate heat from the high-pressure delivery pump 2, a heat dissipation hole 122 is provided on the rear side of the mounting box 12.

[0034] In some embodiments, such as Figure 1 and 2 As shown, the mounting box 12 is provided with doors 123 on both sides. The doors 123 and the mounting box 12 are connected by a rotating structure as in the prior art, which will not be described in detail here. The doors 123 on both sides of the mounting box 12 provide great convenience for daily inspection and maintenance of internal components such as the high-pressure delivery pump 2 and the liquid level monitoring unit 3.

[0035] In some embodiments, such as Figure 3 and 5 As shown, the filtration unit 4 also includes a filter barrel 44, which is a hollow structure. A barrel cover 441 is provided on the top of the filter barrel 44. An annular mounting plate 442 is provided at the bottom of the interior of the filter barrel 44. A lower filter plate 443 is provided on the top of the annular mounting plate 442. A filter rod 444 is connected above the center of the lower filter plate 443. An upper filter plate 445 is connected to the top of the filter rod 444. A filter element 446 is provided between the upper filter plate 445 and the lower filter plate 443. A buffer filter cavity 447 is formed between the filter element 446 and the inner wall of the filter barrel 44. The filter fluid inlet pipe 41 is connected to the buffer filter cavity 447, and the filter fluid outlet pipe 42 is connected to the interior of the annular mounting plate 442. Specifically, in this embodiment, the cutting fluid flows from the filter fluid inlet pipe 41 into the buffer filter chamber 447. After being filtered by the filter element 446, the cutting fluid flows into the annular mounting plate and then flows out from the filter fluid outlet pipe 42 at the bottom of the annular mounting plate 442, completing the filtration of the cutting fluid. The filter section 4, located at the top of the mounting box 12, allows used cutting fluid to enter the filter section 4 via the second water supply pipe 43. After being filtered by the filter element 446, the clean cutting fluid flows back to the sealed water tank 11 via the first water supply pipe 113, forming a complete internal treatment cycle. This ensures that the cutting fluid supplied to the high-pressure pump is always clean.

[0036] In some embodiments, such as Figure 5 As shown, a compression spring 448 is provided at the center of the bottom of the bucket lid 441, and the bottom of the compression spring 448 abuts against the top of the upper filter plate 445. Specifically, in this embodiment, after the bucket lid 441 is fixed, the compression spring 448 will press the upper filter plate 445, thereby pressing the lower filter plate 443 tightly against the annular mounting plate 442.

[0037] In some embodiments, such as Figure 3 and 5 As shown, in order to facilitate the installation of the filter unit 4, the top of the mounting box 12 is provided with a filter mounting groove (not shown in the figure), and the outer wall of the filter barrel 44 is provided with an annular fixing plate 449.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
