Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, and more specifically to a cutting fluid circulation and recovery system. Background Technology

[0002] The robotic automatic support removal and grinding system requires the use of cutting tools to perform milling, cutting and other processes on 3D printed workpieces.

[0003] To ensure cutting efficiency and protect the cutting tool, it is necessary to cool the tool during operation. This means that cutting fluid is continuously supplied to the tool during the operation.

[0004] In existing machining operations, the cutting fluid used in cutting operations is collected and then treated as waste fluid for subsequent recycling.

[0005] It can be seen that this operating method results in a large consumption of cutting fluid, which invisibly increases the processing cost of 3D printed workpieces during the machining process.

[0006] Chinese patent publication number CN218015786U discloses a 3D printing desupport system, including: a worktable, a detection module, a control system, a robotic arm, and an end effector for desupporting. The control system is configured to obtain the position information of the desupported area of ​​the product to be processed and its corresponding actual operation coordinates based on the digital model of the product to be processed established or read by the detection module. The robotic arm guides the end effector on the robotic arm to actively touch the product to be processed and perform desupporting operation on the product to be processed based on the actual operation coordinates corresponding to the real-time position information of the desupported area.

[0007] The aforementioned patented de-support process can be automated, replacing manual operation and reducing labor and production management costs. Compared to manual labor, it offers advantages in efficiency and accuracy, effectively improving the quality control capabilities of post-3D printing processing. Its promotion in the industry demonstrates a certain degree of lean manufacturing. However, the cutting fluid used in the cutting operation is directly scattered near the processed product, not only causing a messy work environment but also making it difficult to recycle the cutting fluid. Utility Model Content

[0008] The purpose of this invention is to address the aforementioned problems in existing technologies by providing a cutting fluid circulation and recovery system that is compact and highly stable.

[0009] To achieve the above objectives, this utility model can be implemented through the following technical solutions:

[0010] A cutting fluid circulation and recovery system includes a machining section comprising a work platform, a robot, and a fixture for positioning workpieces. Both the fixture and the robot are connected to the work platform, with the robot adjacent to the fixture. The system comprises a circulation pump, connecting pipes, a collection tank, and a nozzle. The collection tank is internally hollow and open at the top. The nozzle is fixed to the robot. The collection tank contains a filter assembly that divides it into two independent chambers: a chamber one located near the upper end of the collection tank and a chamber two located below the chamber. Cutting fluid from the work platform can enter chamber one. One end of the connecting pipe is connected to chamber two, and the other end is connected to the nozzle. The circulation pump is connected to the connecting pipe.

[0011] In the aforementioned cutting fluid circulation and recovery system, the working platform has a flow guide port, and the aforementioned fluid collection tank is located directly below the flow guide port.

[0012] In the above-mentioned cutting fluid circulation and recovery system, the upper end of the guide port is larger than its lower end, and the upper end to the lower end of the guide port is an inclined guide surface.

[0013] In the above-mentioned cutting fluid circulation and recovery system, the filter assembly includes filter screen one and filter screen two. Filter screen one divides the collection tank into two adjacent chambers, chamber one and chamber two. The lower part of the collection tank has a liquid outlet located in chamber two. Filter screen two is located inside the collection tank and covers the liquid outlet.

[0014] In the above-mentioned cutting fluid circulation and recovery system, a horizontally arranged partition is connected to the middle of the collection tank. The partition divides the collection tank into two adjacent chambers, chamber one and chamber two. The partition has a through mounting hole, and the filter screen one is fixed to the port of the mounting hole by a flange.

[0015] In the above-mentioned cutting fluid circulation and recovery system, a liquid level sensor is fixedly connected to the upper part of the baffle.

[0016] In the above-described cutting fluid circulation and recovery system, the bottom of the collection tank is equipped with rollers.

[0017] In the aforementioned cutting fluid circulation and recovery system, a handle is connected to the side of the collection tank.

[0018] In the above-mentioned cutting fluid circulation and recovery system, a cover plate is fixedly connected to the upper port of the guide port, and the cover plate has a number of grid-shaped leakage holes.

[0019] In the above-mentioned cutting fluid circulation and recovery system, the cover plate, the guide port and the collection tank form a collection unit, and there are several collection units, which are evenly distributed on the side of the fixture.

[0020] Compared with existing technologies, this cutting fluid circulation and recovery system not only allows the cutting fluid to smoothly enter the collection tank after cutting operations, but also the filter components in the collection tank can effectively filter the cutting fluid after cutting operations. The filtered cutting fluid then re-enters the robot's nozzle, thus effectively reducing operating costs.

[0021] Meanwhile, because the filter assembly filters the cutting fluid twice, it ensures that the cutting fluid entering the nozzle effectively meets the standards for recycling and reuse, and its stability is relatively high.

[0022] In addition, the liquid collection tank is located under the working platform and does not take up extra space. The entire system has a compact structure and high practical value. Attached Figure Description

Detailed Implementation

[0031] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0032] like Figure 1-6As shown, the processing unit includes a work platform 1, a robot 2, and a fixture 3 for positioning workpieces. The fixture 3 and the robot 2 are both connected to the work platform 1, and the robot 2 is adjacent to the fixture 3.

[0033] This cutting fluid circulation and recovery system includes a circulation pump 4, a connecting pipe 5, a collection tank 6, and a nozzle 7. The collection tank 6 is hollow inside and open at the top. The nozzle 7 is fixed to the robot 2. The collection tank 6 has a filter assembly that divides the collection tank 6 into two independent chambers: a chamber 6a near the upper port of the collection tank 6 and a chamber 6b located below the chamber 6a. The cutting fluid at the work platform 1 can enter the chamber 6a. One end of the connecting pipe 5 is connected to the chamber 6b, and the other end of the connecting pipe 5 is connected to the nozzle 7. The circulation pump 4 is connected to the connecting pipe 5.

[0034] Robot 2 has a cutting tool for machining and a nozzle 7 adjacent to the cutting tool. The workpiece to be machined is mounted in a fixture 3. Robot 2 performs corresponding machining operations on the workpiece using the cutting tool. During this process, a cutting fluid circulation and recovery system ensures that there is always an appropriate amount of cutting fluid at the cutting tool.

[0035] Cutting fluid plays a crucial role in the aforementioned machining processes. It not only helps improve machining efficiency and product quality, but also extends tool life and protects machinery and equipment.

[0036] Specifically, cutting fluids used in cutting processes have the following three main functions:

[0037] 1. A large amount of heat is generated during the cutting process, especially at high speeds. Cutting fluid can effectively remove this heat, preventing the workpiece and tool from overheating, thereby avoiding dimensional changes or material deformation caused by excessive temperature.

[0038] 2. Cutting fluid can form a lubricating film between the tool and the workpiece, reducing direct contact between the two, lowering friction, and making the cutting process smoother.

[0039] 3. Cutting fluid can effectively wash away small metal chips and other impurities generated during the cutting process, keep the cutting area clean, prevent chips from re-embedding into the workpiece surface, and improve the quality of cutting.

[0040] After the cutting operation, the cutting fluid enters the collection tank 6. The impurities in the cutting fluid in cavity 6a are filtered by the filter assembly and then enter cavity 6b, where the cutting fluid has already been filtered. Under the action of the circulation pump 4 and the connecting pipe 5, the filtered cutting fluid re-enters the robot's nozzle 7. This ensures a stable circulation of the cutting fluid in the machining section.

[0041] The working platform 1 has a flow guide 1a, and the liquid collection tank 6 is located directly below the flow guide 1a.

[0042] The cutting fluid at the working platform 1 can be stably introduced into the collection tank 6 through the guide port 1a.

[0043] The upper end of the guide port 1a is larger than its lower end, and the upper end to the lower end of the guide port 1a is an inclined guide surface 1a1.

[0044] The guide surface 1a1 allows the cutting fluid to flow smoothly into the collection tank 6.

[0045] The filter assembly includes a first filter screen 8 and a second filter screen 9. The first filter screen 8 divides the liquid collection tank 6 into two adjacent chambers, a first chamber 6a and a second chamber 6b. The lower part of the liquid collection tank 6 has a liquid outlet 6c, which is located at the second chamber 6b. The second filter screen 9 is located inside the liquid collection tank 6 and covers the liquid outlet 6c.

[0046] The cutting fluid in cavity 6a undergoes a first filtration after being processed by filter screen 8. The filtered cutting fluid then enters cavity 6b. During the discharge process from outlet 6c, the cutting fluid in cavity 6b is subjected to a second filtration by filter screen 9, thus ensuring its filtration effect.

[0047] Of course, in order to improve work efficiency and filtration accuracy, the mesh count of filter screen 8 is smaller than that of filter screen 9.

[0048] The liquid collection tank 6 is connected in the middle by a horizontally arranged partition 10, which divides the liquid collection tank 6 into two adjacent chambers, 6a and 6b. The partition 10 has a through mounting hole 10a, and the filter screen 8 is fixed to the port of the mounting hole 10a by a flange.

[0049] The partition 10 not only stably divides the collection tank 6 into two independent chambers, but also provides sufficient space for the filter screen 8 to be connected.

[0050] A liquid level sensor 11 is fixedly connected to the upper part of the partition 10.

[0051] The liquid level sensor 11 can promptly determine the liquid level in the collection tank 6. Of course, the liquid level sensor 11 also needs to work in conjunction with a corresponding warning light or horn. If the liquid level is too low, it will cause damage to the circulation pump 4. Therefore, when the liquid level is too low, the warning light will flash and the horn will sound an alarm.

[0052] The bottom of the liquid collection tank 6 has rollers 12.

[0053] A handle 13 is connected to the side of the liquid collection tank 6.

[0054] When the collection tank 6 needs to be inspected and maintained, the operator can easily pull out the collection tank 6 using the handle 13. During the pulling process, the roller 12 rolls against the ground to ensure that the collection tank 6 can be pulled out smoothly.

[0055] A cover plate 14 is fixedly connected to the upper port of the flow guide 1a, and the cover plate 14 has a plurality of grid-shaped leakage holes 14a.

[0056] Cover plate 14 has two functions:

[0057] First, cover the upper part of the flow guide 1a to prevent personnel or workpieces from falling into the flow guide 1a;

[0058] Secondly, the drain hole 14a allows the cutting fluid entering the cover plate 14 to smoothly enter the guide port 1a.

[0059] The cover plate 14, the guide port 1a and the liquid collection tank 6 form a collection unit. There are several collection units, which are evenly distributed on the side of the clamp 3.

[0060] The setup of multiple collection units allows for more stable collection of cutting fluid. Of course, the filtered cutting fluid will be introduced into the nozzle 7 of robot 2.

[0061] This cutting fluid circulation and recovery system not only allows the cutting fluid to smoothly enter the collection tank after cutting operations, but also the filter components in the collection tank can effectively filter the cutting fluid after cutting operations. The filtered cutting fluid then re-enters the robot's nozzle, thus effectively reducing operating costs.

[0062] Meanwhile, because the filter assembly filters the cutting fluid twice, it ensures that the cutting fluid entering the nozzle effectively meets the standards for recycling and reuse, and its stability is relatively high.

[0063] In addition, the liquid collection tank is located under the working platform and does not take up extra space. The entire system has a compact structure and high practical value.

[0064] like Figure 6 As shown, an appropriate amount of cutting fluid needs to be added to the collection tank before operation. After a period of operation, once the level sensor issues a warning signal, cutting fluid needs to be added again to bring the fluid level back to the set requirement.

[0065] During operation, the cutting fluid flows back to the collection tank. After being filtered by the filter assembly, the filtered cutting fluid is transported back to the robot's nozzle via the circulation pump and connecting pipeline.

[0066] The above-described technical solution of this utility model addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The parts not covered in this application's technical solution are the same as or can be implemented using existing technologies, and will not be described in detail here.

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.
