Abstract
Description
Technical Field
[0001] This invention relates to the field of planing equipment technology, and more specifically, to a high-efficiency and energy-saving multi-stage pump cutting equipment. Background Technology
[0002] Multistage pumps are core power equipment in industrial fluid transportation, water supply and drainage projects, and chemical pressurization. As the core flow-through component of a multistage pump, the impeller's machining accuracy and surface finish directly determine the pump's water delivery efficiency, operational stability, and service life. After machining, burrs are easily generated on the impeller's annular end face and at the stepped joints between the annular and circular surfaces. If burrs remain, they will not only disrupt fluid flow and increase pump energy consumption, but also cause stress concentration, impeller corrosion, and abnormal operating noises, seriously affecting the overall performance of the multistage pump.
[0003] The prior art patent with publication number CN223776161U provides a deburring device for stainless steel impellers of water pumps. The device has a cutting component installed in a receiving groove. The cutting component includes a moving block that moves back and forth in the receiving groove. A clearance groove is provided at the bottom of the moving block, and a cutter is fixedly connected in the clearance groove. The cutter is inclined. A slider is fixedly connected to the top of the moving block and slidably connected in a sliding groove. A spring connects the slider and the sliding groove. A pushing component is provided behind the component to drive the moving block to move. An air blowing component is provided in the clearance groove. The moving block drives the cutter to move and remove burrs from the impeller surface. The air blower blows air into the clearance groove to prevent the cut burrs from getting stuck in the clearance groove.
[0004] The existing device, which removes burrs from the impeller surface by lateral planing, cannot specifically cut off the root-connected burrs at the junction of the top ring and the annular surface of the impeller. This results in incomplete burr removal, requiring subsequent manual rework, leading to low processing efficiency. Furthermore, as the cutter head wears down, the cutting resistance from the burrs increases, causing excessive local temperature rise during cutting. The air blowing structure is ineffective in cooling the cutter head, further exacerbating wear and dulling the cutting edge. This results in a poor cutting edge shape, leading to poor impeller surface roughness during planing and deburring, which in turn makes it easier to generate burrs, affecting the device's surface treatment effect and ultimately impacting the impeller processing quality.
[0005] In view of this, the present invention proposes a cutting device for efficiently and stably removing burrs from the surface of a multi-stage pump impeller. Summary of the Invention
[0006] Technical problem to be solved: The purpose of this invention is to provide a high-efficiency and energy-saving cutting device for processing multi-stage pumps, which solves the technical problems mentioned in the background art.
[0007] Technical Solution: The present invention provides a high-efficiency and energy-saving cutting device for processing multi-stage pumps, including a base plate. A rotating seat and a slide rail frame are fixed on the top surface of the base plate. The rotating seat is used to support the impeller of the multi-stage pump. A constant pressure component is slidably connected inside the slide rail frame. One end of the constant pressure component is set on the top of the rotating seat. A planing component is slidably connected to one side of the constant pressure component. The constant pressure component slides down on the slide rail frame to press against the top ring of the impeller. The planing component slides on the constant pressure component to plan the burrs on the annular surface of the impeller. The planing assembly includes two second electric sliders slidably connected to a constant pressure assembly. A fixed plate is horizontally connected across the bottom surface of the two second electric sliders. A pneumatic rod and an air jet component are connected through the fixed plate. A push plate is connected to the telescopic bottom end of the pneumatic rod. A planing cutter head is fixed on one side of the push plate. The air jet component is located on the top of the planing cutter head and is used to spray air in the direction of the cutting edge of the planing cutter head. A heat pipe is installed inside the planing cutter head. The distance between the bottom end of the heat pipe and the bottom surface of the planing cutter head is set as the safe wear thickness of the planing cutter head.
[0008] Furthermore, the planing head is arranged radially along the rotary seat in the direction of translational planing.
[0009] Furthermore, the planing head has an arc-shaped structure. The planing head removes burrs on the impeller annular surface by translating and makes the planing head fit against the outer wall of the top annular ring of the impeller. The planing head pulls the scraper plate to rise synchronously through the pneumatic rod to cut off the burrs between the top annular ring of the impeller and the annular surface.
[0010] Furthermore, the air jet component includes an air pump fixed to the top surface of the fixed plate. The bottom end of the air pump is the air outlet and is connected to an electric valve. The electric valve is connected to the top surface of the shovel push plate. A one-way valve is connected to one outlet of the electric valve, and an air jet pipe is connected to one end of the one-way valve.
[0011] Furthermore, the electric valve is an electric three-way valve, the inside of the shovel pusher plate is a hollow structure, and multiple air jet holes communicating with the hollow structure are opened on both sides of the shovel pusher plate. The bottom outlet of the electric valve is connected to the hollow cavity inside the shovel pusher plate.
[0012] Furthermore, the jet pipe has an arc-shaped structure and is arranged parallel to the top of the planing head. Multiple nozzles are arranged through the bottom surface of the jet pipe, and the jet direction of the nozzles is directed towards the cutting edge of the planing head.
[0013] Furthermore, the air spray component also includes a cold air gun slidably connected inside the fixed plate, with the bottom end of the cold air gun being the cold air outlet end, and the cold air outlet end of the cold air gun being internally connected to the outlet end of the one-way valve.
[0014] Furthermore, a piston is inserted inside the planing head, with one end of the piston inserted into the heat pipe. A pressure sensor is embedded and fixed on the side of the push plate near the planing head, and an indicator light is provided on the top surface of the push plate. One end of the piston is attached to the side wall of the pressure sensor.
[0015] Furthermore, the constant pressure assembly includes a first electric slider slidably connected inside the slide rail frame. Two slide rods are connected to the side wall of the first electric slider. Two second electric sliders are slidably connected to the two slide rods respectively. A fixed plug is sleeved across the outer wall of the two slide rods away from the first electric slider. An arc-shaped limiting ring is sleeved on the outer wall of the bottom end of the fixed plug. The limiting ring has an open structure on the side near the second electric slider. An inner insertion ring is fixed at the bottom end of the fixed plug. The fixed plug, the limiting ring, the inner insertion ring, and the rotating seat are located on the same vertical center line.
[0016] Furthermore, the arc of the outer wall at the bottom of the fixed plug is the same as the arc of the cutting edge of the planer head, and the planer head fits against the outer wall at the bottom of the fixed plug through an upward engagement.
[0017] Beneficial effects: One or more technical solutions provided in this invention have at least the following technical effects or advantages: 1. The impeller is positioned by a sliding constant pressure component in conjunction with a rotating seat, and the top ring of the impeller is pressed by a pressure structure. The height is automatically calibrated so that the bottom surface of the planing component is flush with the annular surface of the impeller. This achieves precise workpiece positioning and synchronous calibration of the tool height. The operation is simple and ensures the planing and cutting accuracy of the subsequent planing head on the annular surface of the impeller.
[0018] 2. A planing component is slidably arranged on the constant pressure component slide rod. The planing head can move along the impeller surface to remove surface burrs. It can cut the surface burrs directly from the root, remove the burrs thoroughly, and avoid generating more debris, thereby improving the cleaning efficiency and effect of large burrs on the impeller surface.
[0019] 3. The planing assembly integrates a pneumatic rod, a scraper plate, an arc-shaped planing cutter head, and an air jet component. After the surface planing is completed by translation, the pneumatic rod can lift the planing cutter head upward to cut off the root burrs at the junction of the top ring and the annular surface of the impeller. This removes both surface and root burrs, resulting in more thorough burr removal and improved processing quality of the impeller.
[0020] 4. The air jet component continuously sprays air at the cutting edge, simultaneously cooling the planing head and blowing away debris, ensuring the stability and effectiveness of the planing head in deburring, reducing the temperature rise of the planing head, slowing down wear, and extending the service life of the planing head.
[0021] 5. By installing a heat pipe inside the planer head, the working fluid evaporates and rises inside the heat pipe. The evaporated working fluid transfers heat to the top of the heat pipe, and then condenses and flows back through the wick. The working fluid circulates and transfers heat, thereby cooling the bottom surface of the planer head that is cutting burrs, thus improving the cooling effect of the planer head.
[0022] 6. Set the distance between the bottom of the heat pipe and the bottom surface of the planer head as the safe wear thickness. When the safe wear thickness on the bottom surface of the planer head is completely worn, the bottom of the heat pipe will also be worn through, causing the working fluid inside the heat pipe to flow out and vaporize. The worker can observe that the safe wear thickness of the planer head has been completely worn, so as to adjust the planing work.
[0023] 7. The electric valve adopts a three-way structure. One channel connects to the air jet pipe and is aligned with the planing head, while the other channel connects to the internal cavity of the push plate. Multiple sets of air jet holes are opened on both sides of the push plate. After switching the air path, high-pressure gas is sprayed out from both sides of the push plate, sweeping the impeller annular surface over a wide area and cleaning the debris in the entire processing area. The dual-channel air jet design takes into account both local cooling of the planing head and cleaning of debris in the entire workpiece area, ensuring no debris residue throughout the processing and preventing workpiece scratches.
[0024] 8. The fixed plate slides to assemble the cold air gun, which is connected to the air jet pipe through a one-way valve. When the wear of the planing cutter head exceeds the standard, the air pump is turned off and the cold air gun is connected. The vortex tube generates a low-temperature dry airflow, which on the one hand greatly enhances the cooling of the planing cutter head, and avoids the large amount of heat generated by the increased cutting resistance after wear, which will concentrate on the planing cutter head and further accelerate wear, thereby extending the service life of the planing cutter head. On the other hand, the low temperature embrittles the metal burrs, reduces the cutting resistance of the burrs on the planing cutter head, thereby reducing the heat generated during planing and making it easier to completely cut off the burrs, ensuring the burr removal effect of planing.
[0025] 9. By setting a piston to fit onto the pressure sensor, the working fluid inside the heat pipe evaporates and vaporizes under the high temperature of the planing head, increasing the internal pressure of the heat pipe. Thus, when the planing head is at a high temperature, the gas pressure inside the heat pipe pushes the piston to act on the pressure sensor, indirectly monitoring the working temperature of the planing head through pressure. When the planing head wears down to the bottom of the heat pipe and wears through it, the working fluid inside the heat pipe sprays out from the bottom. When the working fluid is sprayed out, it vaporizes and carries away the heat of the planing head, assisting in cooling the planing head and causing a sudden drop in the monitoring pressure. The main controller then determines that the planing head is excessively worn and activates the cold air gun to quickly cool the planing head and burrs. The operation is efficient and ensures that the planing head can continue to remove burrs.
[0026] 10. The limiting ring opening structure avoids the machining area, exposing the annular surface to be machined on the side facing the cutter head, which facilitates the planing cutter head to rise and remove burrs without interfering with the planing operation, and also facilitates the removal of burrs.
[0027] 11. The curvature of the outer wall of the bottom of the fixed plug is completely consistent with the arc of the cutting edge of the planer head. After the planer head moves upward to cut off the burrs, the arc cutting edge fits against the outer wall of the bottom of the fixed plug so that the planer head can stably drive the burrs upward, so that the burrs can completely separate from the impeller and be blown away.

[0043] Reference Figures 1-11 This invention provides a high-efficiency and energy-saving cutting device for processing multi-stage pumps, including a base plate 100. A rotating seat 200 and a slide rail frame 300 are fixed on the top surface of the base plate 100. The rotating seat 200 supports the impeller of the multi-stage pump. A constant pressure component 400 is slidably connected inside the slide rail frame 300. One end of the constant pressure component 400 is disposed on the top of the rotating seat 200. A planing component 500 is slidably connected to one side of the constant pressure component 400. The constant pressure component 400 slides down on the slide rail frame 300 to press against the top ring of the impeller, and the bottom surface of the planing component 500 is flush with the annular surface of the impeller. The planing component 500 slides on the constant pressure component 400 to plan the burrs on the annular surface of the impeller. The planing assembly 500 includes two second electric sliders 510 slidably connected to the constant pressure assembly 400. A fixed plate 520 is horizontally connected across the bottom surface of the two second electric sliders 510. A pneumatic rod 530 and an air jet component 560 are connected through the fixed plate 520. A shovel plate 540 is connected to the telescopic bottom end of the pneumatic rod 530. A planing head 550 is fixed on one side of the shovel plate 540. The air jet component 560 is located on the top of the planing head 550 and is used to spray air in the cutting direction of the planing head 550. A heat pipe 551 is provided inside the planing head 550. The distance between the bottom end of the heat pipe 551 and the bottom surface of the planing head 550 is set as the safe wear thickness of the planing head 550. The impeller is positioned by the sliding constant pressure component 400 in conjunction with the rotating seat 200, and the top ring of the impeller is pressed by the pressure structure. The height is automatically calibrated so that the bottom surface of the planing component 500 is flush with the annular surface of the impeller, realizing precise workpiece positioning and synchronous calibration of the tool height. The operation is simple and ensures the planing and cutting accuracy of the subsequent planing head 550 on the annular surface of the impeller. The constant pressure component 400 slides on the slide bar 420 to arrange the planing component 500. The planing head 550 can move along the impeller surface to remove surface burrs. It can cut the surface burrs directly from the root, remove the burrs thoroughly, and avoid generating more debris, thus improving the cleaning efficiency and effect of large burrs on the impeller surface. The planing assembly 500 integrates a pneumatic rod 530, a scraper plate 540, an arc planing head 550, and an air jet component 560. After the surface planing is completed by translation, the pneumatic rod 530 can lift the planing head 550 upward to cut off the root burrs at the junction of the top ring and the annular surface of the impeller. This removes both surface and root burrs, resulting in more thorough burr removal and improved processing quality of the impeller. The air jet component 560 continuously sprays air at the cutting edge, simultaneously cooling the planing head 550 and blowing away debris, ensuring the stability and effectiveness of the planing head 550 in removing burrs, reducing the temperature rise of the planing head 550, slowing down wear, and extending the service life of the planing head 550. By installing a heat pipe 551 inside the planing head 550, the working fluid inside the heat pipe 551 evaporates and rises. The evaporated working fluid transfers heat to the top of the heat pipe 551, and then condenses and flows back through the liquid wick on the inner wall of the heat pipe 551. The working fluid circulates and transfers heat, thereby cooling the bottom surface of the planing head 550 that is planing burrs, and improving the cooling effect of the planing head 550. The distance between the bottom end of the heat pipe 551 and the bottom surface of the planer head 550 is set as the safe wear thickness. When the safe wear thickness of the bottom surface of the planer head 550 is completely worn, the bottom end of the heat pipe 551 will also be worn through, causing the working fluid inside the heat pipe 551 to flow out and vaporize. The worker can observe that the safe wear thickness of the planer head 550 has been completely worn, so as to adjust the work of planing burrs.
[0044] In this embodiment, the planing head 550 is arranged radially along the rotating seat 200 in the translational planing direction; the planing head 550 is arranged radially along the rotating seat 200 in the translational path, the cutting force is perpendicular to the root of the burr, the planing resistance is small, and the multiple cuts combined with the rotating impeller can cover the annular surface of the impeller, which can smoothly scrape off the burrs that are spread all over the annular surface, ensuring that the machined surface of the impeller is flat and free of residual burrs.
[0045] In this embodiment, the planing head 550 has an arc-shaped structure. The planing head 550 removes burrs on the impeller annular surface by translating and makes the planing head 550 fit against the outer wall of the top annular surface of the impeller. The planing head 550 pulls the scraper plate 540 to rise synchronously through the pneumatic rod 530 to cut off the burrs between the top annular surface of the impeller. The planing head 550 adopts an arc structure, which matches and fits the outer wall of the ring at the top of the impeller. After horizontal translation to complete the deburring of the annular surface, the pneumatic rod 530 pulls the scraper plate 540 and the planing head 550 to rise simultaneously, and vertically lifts along the outer wall of the ring to cut off the burrs from the root. The two-stage deburring is completed in layers, eliminating the need for manual rework and improving the processing efficiency of deburring the impeller.
[0046] In this embodiment, the air jet component 560 includes an air pump 561 fixed to the top surface of the fixing plate 520. The bottom end of the air pump 561 is the air outlet and is connected to an electric valve 562. The electric valve 562 is connected to the top surface of the push plate 540. One-way valve 563 is connected to one outlet of the electric valve 562, and one end of the one-way valve 563 is connected to an air jet pipe 564. The air jet component 560 uses the air pump 561 as the air source, and connects to the air jet pipe 564 after connecting the electric valve 562 and the one-way valve 563 in series. The one-way valve 563 blocks the airflow backflow and stabilizes the air pressure at the nozzle. The electric valve 562 can switch the air path on and off. Under normal conditions, the air pump 561 supplies air to complete the conventional cooling and purging. Through the one-way pressure stabilizing air path, the jet force is stabilized, ensuring the stability of cooling the planing head 550 and blowing away burrs and chips.
[0047] In this embodiment, the electric valve 562 is an electric three-way valve. The inside of the push plate 540 is a hollow structure. Multiple air jet holes 541 communicating with the hollow structure are opened on both sides of the push plate 540. The bottom outlet of the electric valve 562 is connected to the hollow cavity inside the push plate 540. The electric valve 562 adopts a three-way structure. One path is connected to the air jet pipe 564 aligned with the planing head 550, and the other path is connected to the hollow cavity inside the push plate 540. Multiple sets of air jet holes 541 are opened on both sides of the push plate 540. After switching the air path, high-pressure gas is sprayed out from both sides of the push plate 540, which sweeps the impeller annular surface over a large area and cleans the debris in the entire processing area. The dual-path air jet design takes into account both local cooling of the planing head 550 and full-area debris cleaning of the workpiece. There is no debris residue during the entire processing, and workpiece scratches are prevented.
[0048] In this embodiment, the jet pipe 564 has an arc-shaped structure and is arranged parallel to the top of the planing head 550. Multiple nozzles are arranged through the bottom surface of the jet pipe 564, and the jet direction of the nozzles is directed towards the cutting edge of the planing head 550. The jet pipe 564 adopts an arc shape parallel to the planing head 550, and multiple sets of nozzles are arranged along the entire length of the cutting edge. All nozzles are uniformly directed towards the cutting edge. The high-pressure airflow fully covers and wraps the cutting area, centrally cooling the planing head 550 and blowing away cutting chips. The concentric arc pipe provides centralized air supply, and the cooling coverage is complete. Under the same cooling effect, the air consumption is smaller, saving energy and continuously cooling the cutting edge. This extends the service life of the planing head 550 and reduces downtime for tool replacement.
[0049] In this embodiment, the air spray component 560 further includes a cold air gun 565 slidably connected inside the fixed plate 520. The bottom end of the cold air gun 565 is the cold air outlet end, and the cold air outlet end of the cold air gun 565 is internally connected to the outlet end of the one-way valve 563. The fixed plate 520 is slidably fitted with a cold air gun 565. The cold air gun 565 is connected to the jet pipe 564 through a one-way valve 563. When the wear of the planing cutter head 550 exceeds the standard, the air pump 561 is turned off and the cold air gun 565 is connected. The vortex tube generates a low-temperature dry airflow, which on the one hand greatly enhances the cooling of the planing cutter head 550, and avoids the large amount of heat generated by the increased cutting resistance after wear, which will be concentrated on the planing cutter head 550 and further accelerate the wear, thereby extending the service life of the planing cutter head 550. On the other hand, the low temperature embrittles the metal burrs, reduces the cutting resistance of the burrs on the planing cutter head 550, thereby reducing the heat generated during planing and making it easier to completely cut off the burrs, ensuring the burr removal effect of planing. Because the use of the 565 cold air gun with low-temperature jetting consumes a lot of energy, it is only used after the wear of the 550 planing cutter head exceeds the standard, in order to accurately ensure the planing needs and save energy.
[0050] In this embodiment, a piston 552 is inserted inside the planing head 550, one end of the piston 552 is inserted into the heat pipe 551, a pressure sensor 542 is embedded and fixed on the side of the push plate 540 near the planing head 550, an indicator light 543 is provided on the top surface of the push plate 540, and one end of the piston 552 is attached to the side wall of the pressure sensor 542. By setting the piston 552 to be attached to the pressure sensor 542, the working fluid inside the heat pipe 551 evaporates and vaporizes under the high temperature of the planing head 550, increasing the internal pressure of the heat pipe 551. Thus, when the planing head 550 is at a high temperature, the internal pressure of the heat pipe 551 pushes the piston 552 against the pressure sensor 542, indirectly monitoring the working temperature of the planing head 542 through pressure. When the detected pressure is within the normal range, the main controller indicator light 543 displays green. When the temperature is abnormal, the monitored pressure is too high, and the main controller determines that the planing head 550 is worn. The main controller indicator light 543 displays yellow. When the planer head 550 wears down to the bottom of the heat pipe 551 and wears through the bottom of the heat pipe 551, the working fluid inside the heat pipe 551 sprays out from the bottom. When the working fluid is sprayed out, it vaporizes and carries away the heat of the planer head 550, assisting in cooling the planer head 550 and causing the monitoring pressure to drop sharply. The main controller then determines that the planer head 550 is excessively worn, and the main controller indicator light 543 displays red. At the same time, the cold air gun 565 is activated to quickly cool the planer head 550 and the burrs. The operation is efficient and ensures that the planer head can continue to remove burrs.
[0051] In this embodiment, the constant pressure assembly 400 includes a first electric slider 410 slidably connected inside the slide rail frame 300. Two slide rods 420 are connected to the side wall of the first electric slider 410. Two second electric sliders 510 are slidably connected to the two slide rods 420 respectively. A fixed plug 430 is sleeved across the outer wall of the two slide rods 420 away from the first electric slider 410. An arc-shaped limiting ring 432 is sleeved on the outer wall of the bottom end of the fixed plug 430. The limiting ring 432 has an open structure on the side near the second electric slider 510. An inner insertion ring 431 is fixed at the bottom end of the fixed plug 430. The fixed plug 430, the limiting ring 432, the inner insertion ring 431 and the rotating seat 200 are located on the same vertical center line. The constant pressure component 400 is raised and lowered along the slide rail frame 300 by the first electric slider 410. Two parallel slide rods 420 provide a stable translation track for the planing component 500. The fixed plug 430 at the end of the slide rod 420 is coaxially equipped with an arc-shaped limiting ring 432 and an inner insertion ring 431. All components share the same vertical center line with the rotating seat 200 and the impeller, automatically centering to ensure uniform cutting depth at all parts of the impeller's annular circumference, thereby ensuring consistent processing and improving the impeller's processing quality. The limiting ring 432 has an open structure to avoid the machining area, exposing the annular surface to be machined on the side facing the cutter head. This facilitates the planing cutter head 550 to rise and remove burrs without interfering with the planing operation, and also makes it easy to blow away the burrs.
[0052] In this embodiment, the arc of the bottom outer wall of the fixed plug 430 is the same as the arc of the cutting edge of the planer head 550, and the planer head 550 is fitted to the bottom outer wall of the fixed plug 430 by rising and engaging. The curvature of the outer wall at the bottom of the fixed plug 430 is completely consistent with the arc of the cutting edge of the planer head 550. After the planer head 550 moves upward to cut off the burrs, the arc cutting edge fits against the outer wall at the bottom of the fixed plug 430 so that the planer head 550 can stably drive the burrs upward, so that the burrs can completely separate from the impeller and be blown away.
[0053] Specifically, according to Figures 1-11 As shown, the impeller of the multistage pump is placed on the rotating seat 200. The limiting post inside the rotating seat 200 is inserted into the impeller, so that the impeller can be driven to rotate by the rotating seat 200. The main controller controls the first electric slider 410 to slide downward inside the slide rail frame 300. The first electric slider 410 drives the planing assembly 500 on the slide rod 420 to fall down as a whole, so that the bottom surface of the push plate 540 and the planing head 550 is flush with the annular surface of the impeller, and the fixed plug 430 falls down, inserting the inner ring 431 into the impeller. The fixed plug 430 fits against the top ring of the impeller. The limiting ring 432 is sleeved on the outer wall of the top ring of the impeller, and the opening of the limiting ring 432 faces the direction of the planing head 550, thereby exposing the area of the top ring of the impeller close to the planing head 550, which facilitates the subsequent removal of burrs by the planing head 550, thereby completing the positioning of the impeller. Then, the main controller activates the second electric slider 510 and the air pump 561. The second electric slider 510 slides on the slide rod 420, driving the fixed plate 520 to move the push plate 540 towards the fixed plug 430, so that the planing head 550 removes burrs along the diameter direction of the impeller annular surface. Then, the push plate fits against the annular surface of the impeller to ensure the stability of the planing head 550 during translational planing. During the burr removal process, the air pump 561 inflates, and the main controller controls the electric valve 562 and the one-way valve 563 to connect, so that air passes through the electric valve 562, the one-way valve 563 and the air jet pipe 564 in sequence, and is ejected through multiple nozzles on the air jet pipe 564. The air jet cools the planing head 550, and the planing head 550 combines with... The heat pipe 551 utilizes the evaporation of the working fluid, which can be exemplarily perfluorohexanone. The evaporating working fluid transfers heat to the top of the heat pipe 551, and then condenses and flows back through the wick on the inner wall of the heat pipe 551. The working fluid circulates and transfers heat, thereby cooling the bottom surface of the planing head 550 that is cutting burrs, improving the cooling effect on the planing head 550, and preventing the planing head 550 from being easily worn due to local high temperature during planing, thus extending the service life of the planing head 550. At the same time, the air jet can blow away the burrs removed, ensuring the cleanliness of the impeller annular surface in the area to be planed, avoiding interference with the movement of the planing head 550 during planing, and thus ensuring the stability of the planing head 550 in removing burrs. As the planing cutter head 550 moves to the stepped position between the impeller top ring and the annular surface to remove burrs, the arc-shaped cutting edge of the planing cutter head 550 fits against the exposed outer wall of the impeller top ring. The main controller controls the pneumatic rod 530 to start, which pulls the push plate 540 upward. The planing cutter head 550 rises against the outer wall of the impeller top ring, completely cutting off the root of the burr. The burr is then blown away by air from the nozzle until the planing cutter head 550 rises and the arc-shaped cutting edge fits against the bottom outer wall of the fixed plug 430. Then, the main controller controls the electric valve 562 to connect with the internal cavity of the push plate 540, and the air pump... 561 air is injected through jet hole 541 onto the impeller annular surface to clean the next adjacent deburring area on the annular surface. At the same time, the main controller starts the rotating seat 200 to rotate the impeller, rotating the area to be deburred to the bottom of the push plate 540. The second electric slider 510 is controlled to slide on the slide rod 420 toward the first electric slider 410, moving the planing head 550 to the top of the outer periphery of the impeller. The main controller then starts the pneumatic rod 530 to push the push plate 540 down, making the bottom surface of the push plate 540 and the planing head 550 flush with the annular surface of the impeller. The same steps are then used to plan the next deburring area. During long-term planing and deburring, the planer head 550 will wear. The piston 552 is attached to the pressure sensor 542. The working liquid inside the heat pipe 551 evaporates and vaporizes under the high temperature of the planer head, increasing the internal pressure of the heat pipe 551. Thus, when the planer head 550 is at a high temperature, the gas pressure inside the heat pipe 551 pushes the piston 552 to act on the pressure sensor 542. The working temperature of the planer head 542 is indirectly monitored through pressure. When the detected pressure is within the normal range, the main controller control indicator 543 shows green. When the temperature is abnormal, the monitored pressure is too high, and the main controller determines that the planer head 550 is worn. The main controller control indicator shows yellow. The planer head 550 can still plan normally within the wear requirement range, maximizing the service life of the planer head 550. Once the safe wear thickness of the planing cutter head 550 is reached, if burrs are continuously planed directly, the worn planing cutter head 550 will generate a large amount of heat, reducing the planing effect and potentially producing more burrs after planing. However, at this point, because the bottom of the heat pipe 551 will also wear through, the working fluid inside the heat pipe 551 will spray out from the bottom. When the working fluid is sprayed out, it vaporizes and carries away the heat from the planing cutter head 550, assisting in cooling the planing cutter head 550. In particular, the working fluid uses perfluorohexanone to enhance the cooling effect, and the spraying of the working fluid causes a sudden drop in the monitoring pressure. The main controller then determines that the planing cutter head 550 is excessively worn, and the main controller control indicator light 543 turns red. To further extend the service life of the planing head 550 and avoid interruptions in the planing and deburring process, the main controller shuts down the air pump 561 and starts an external air compressor to fill the cold air gun 565 with dry compressed air. The cold air gun 565 uses vortex tube technology to generate a low-temperature airflow, which is then sprayed out through the jet pipe 564 towards the planing head 550. This not only improves the cooling effect on the planing head 550 but also rapidly cools and embrittles the burrs on the impeller surface, making them easier to cut and remove. This ensures the deburring effect, slows down further wear of the planing head 550, and guarantees the processing quality of the multi-stage pump impeller.
