Description

Technical Field

[0001] This invention relates to the field of aircraft parts processing technology, specifically to a cooling device for heat treatment of aircraft parts. Background Technology

[0002] Heat treatment, as a common materials processing technology, has wide applications in various fields, including machinery manufacturing, automotive manufacturing, aerospace manufacturing, and electronics manufacturing. It can be used to manufacture aircraft engine parts, wheel hubs, aviation bolts, missile components, and more. Heat treatment improves the strength, heat resistance, and corrosion resistance of materials, meeting the aerospace industry's requirements for high strength, lightweight, and high performance. Aircraft parts often require heat treatment during processing, using heating, holding, and cooling to achieve the desired microstructure and properties. After heat treatment, aircraft parts need to undergo cooling, which traditionally relies on air cooling or cooling oil cooling.

[0003] Traditional cooling oil cooling processes involve placing heat-treated aircraft parts in a tank containing cooling oil for cooling. However, this process generates a significant amount of impurities in the cooling oil. Without effective cleaning, these impurities adhere to the aircraft parts during subsequent cooling processes, affecting their processing quality. Frequent oil replacements are necessary, which is inconvenient, and the cooling oil cannot be effectively recycled. Therefore, we propose a cooling device for heat-treated aircraft parts to address these issues. Summary of the Invention

[0008] Preferably, the bottom of the slow oil chamber is provided with an oil drain pipe, which is fixedly clamped in the outer filter cylinder. The end of the oil drain pipe extends out of the outer wall of the outer filter cylinder. An oil guide pump is fixedly installed at the end of the oil drain pipe away from the outer filter cylinder. An L-shaped bend is fixedly installed at the output end of the oil guide pump. An oil return pipe is fixedly installed at the top of the cooling tank. The top end of the L-shaped bend and the bottom end of the oil return pipe are fixedly installed.

[0009] Preferably, the bottom of the discharge pipe extends out of the bottom end of the filter outer cylinder, a crown gear is fixedly sleeved on the bottom of the discharge pipe, a drive gear is meshed with the side end of the crown gear, a drive shaft is fixedly installed in the middle of the drive gear, the drive shaft is rotatably installed at the bottom end of the filter outer cylinder, a first motor is fixedly installed on the side of the bottom end of the filter outer cylinder near the drive shaft, and the drive end of the first motor and the end of the drive shaft are coaxially fixedly installed.

[0010] Preferably, the waste discharge assembly includes a waste discharge hopper frame, which is fixedly installed on the top inner side of the discharge pipe. A waste discharge pipe is fixedly installed at the bottom end of the waste discharge hopper frame, and the discharge pipe extends from the bottom of the waste discharge pipe. A waste discharge cylinder is slidably engaged in the waste discharge pipe. The upper surface of the waste discharge cylinder is provided with a sealing structure. A plurality of evenly distributed waste discharge slots are opened at the top of the waste discharge cylinder. Two symmetrically distributed sliding strips are fixedly installed on the outer wall of the waste discharge cylinder. A sliding groove is opened on the inner wall of the waste discharge pipe to cooperate with the sliding strips. The sliding strips are slidably engaged in the sliding groove. A waste discharge pipe extends from the bottom of the waste discharge cylinder. A bearing is fixedly sleeved on the bottom of the waste discharge cylinder. A lifting frame is fixedly installed on the outside of the bearing. A lifting cylinder is fixedly installed on the side of the bottom of the filter outer cylinder near the lifting frame. The drive end of the lifting cylinder is fixedly installed with the lifting frame.

[0011] Preferably, the primary filtration mechanism includes two symmetrically distributed filter side frames, which are fixedly installed in the cooling tank. The filter side frames are inclined, with their bottoms extending to the middle of the bottom of the oil drain frame. Drive rollers are rotatably mounted on the top and bottom of the filter side frames. Drive belts are movably sleeved on the outer sides of the two drive rollers. Multiple evenly distributed filter baffles are fixedly installed on the outer surface of the drive belts. Multiple evenly distributed second filter slots are formed on the drive belts and filter baffles. A second motor is fixedly installed on the top outer side of the filter side frames, and the drive end of the second motor and the end of the corresponding drive roller are coaxially fixedly installed.

[0012] Preferably, the method of using the cooling device includes the following steps:

[0013] Step 1: Inject cooling oil into the cooling tank, place the heat-treated aircraft parts in the rack, control the linear electric rail to move the aircraft parts horizontally, and control the lifting rod to lower the aircraft parts. Place the heat-treated aircraft parts in the cooling tank containing cooling oil for cooling. During cooling, a lot of impurities are generated. The impurities are suspended in the cooling oil and gradually deposited in the oil drain frame.

[0014] Step 2: Control the second motor to drive the corresponding transmission roller to rotate, thereby driving the transmission belt to drive multiple filter plates. Since multiple second filter slots are provided, large particles of impurities that gradually deposit in the oil drain frame are sequentially placed on the filter plates at the bottom position. Through the transmission of the filter plates, they move to the top position of the primary filtration mechanism, detach from the upper surface of the cooling oil, and are discharged from the cooling tank, thus performing primary filtration and cleaning of large particles of impurities in the cooling oil.

[0015] Step 3: Control the start of the first motor to drive the drive shaft to rotate, which in turn drives the drive gear to rotate, which in turn drives the crown gear and the discharge pipe to rotate at high speed. This causes the inner filter cylinder to rotate at high speed and stably in the outer filter cylinder. Control the start of the oil control valve. The cooling oil after filtering large particles of impurities is introduced into the inner filter cylinder through the feed pipe and feed tube. With the high speed of the inner filter cylinder, the cooling oil undergoes secondary filtration under the action of centrifugation. Small particles of impurities are retained in the inner filter cylinder and gradually enter the discharge pipe. The cooling oil is introduced into the slow oil chamber through multiple first filter channels for buffering and secondary centrifugal filtration.

[0016] Step 4: Control the start of the oil pump. The multi-stage filtered cooling oil buffered in the oil buffer chamber circulates into the cooling tank through the oil drain pipe, oil pump, L-shaped bend, and return oil pipe for secondary recycling after filtration, eliminating the need for frequent replacement of the cooling oil.

[0017] Step 5: Small particulate impurities gradually enter the discharge pipe and enter the waste discharge hopper frame. After the cooling oil has been filtered through multiple stages and all the filtered cooling oil has been recycled for reuse, the lifting cylinder is activated to drive the lifting frame and bearing to move the waste discharge cylinder upward. Multiple waste discharge channels move to the bottom of the waste discharge hopper frame, and the small particulate impurities entering the waste discharge hopper frame are automatically discharged through multiple waste discharge channels, thus automatically cleaning the impurities.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. By setting up a primary filtration mechanism and a secondary filtration mechanism, and using a cooling tank, the heat-treated aircraft parts are cooled, and the primary filtration and cleaning of large particulate impurities in the cooling oil is achieved. At the same time, the cooling oil is subjected to secondary centrifugal filtration to prevent impurities from adhering to the aircraft parts during subsequent cooling, which would affect the processing quality of the aircraft parts. Furthermore, the filtered oil can be recycled and reused, eliminating the need for frequent replacement of the cooling oil and improving the overall performance of the cooling system.

[0020] 2. By setting up a waste discharge component, after the cooling oil has undergone multi-stage filtration and all the filtered cooling oil has been recycled for reuse, the lifting cylinder is activated to drive the lifting frame and bearing to move the waste discharge cylinder upward. Multiple waste discharge channels move to the bottom of the waste discharge hopper frame, and small particulate impurities that have entered the waste discharge hopper frame are automatically discharged through multiple waste discharge channels, thus automatically cleaning the impurities and further improving the overall performance of the cooling device.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example: Figure 1-8 As shown, the present invention provides a cooling device for heat treatment of aircraft parts, including a device base frame 1 and a device top frame 2. A cooling tank 3 is fixedly installed on the top of the device base frame 1, and cooling oil is injected into the cooling tank 3. An oil drain frame 31 is integrally formed at the bottom of the cooling tank 3.

[0033] The cooling tank 3 is equipped with a primary filtration mechanism 4. A secondary filtration mechanism 5 is fixedly installed in the middle of the device base frame 1. A waste discharge assembly 6 is provided at the bottom of the secondary filtration mechanism 5. Two symmetrically distributed linear electric rails 7 are fixedly installed at the bottom of the device top frame 2. A lifting rod 71 is fixedly installed at the drive end of the linear electric rails 7. A shelf 8 is fixedly installed at the drive end of the lifting rod 71. In use, the heat-treated aircraft parts are placed in the shelf 8. The linear electric rails 7 are activated to control the translation of the aircraft parts, and the lifting rod 71 is activated to control the descent of the aircraft parts. The heat-treated aircraft parts are placed in the cooling tank 3 containing cooling oil for cooling. During cooling, a lot of impurities are generated. The impurities are suspended in the cooling oil and gradually deposited in the oil discharge hopper frame 31.

[0034] The primary filtration mechanism 4 includes two symmetrically distributed filter side frames 41, which are fixedly installed in the cooling tank 3. The filter side frames 41 are inclined and their bottoms extend to the middle of the bottom of the oil drain frame 31. The top and bottom of the filter side frames 41 are rotatably mounted with drive rollers 42, and drive belts 43 are movably sleeved on the outer sides of the two drive rollers 42. A second motor 45 is fixedly installed on the top outer side of the filter side frame 41. The drive end of the second motor 45 and the end of the corresponding drive roller 42 are coaxially fixedly installed. The second motor 45 is turned on to drive the corresponding drive roller 42 to rotate, thereby driving the drive belts 43 to perform transmission.

[0035] Multiple evenly distributed filter plates 44 are fixedly installed on the outer surface of the transmission belt 43. Multiple evenly distributed second filter grooves 401 are opened on the transmission belt 43 and the filter plates 44. The transmission belt 43 drives the multiple filter plates 44 to move. Due to the multiple second filter grooves 401, large particles of impurities that gradually deposit in the oil drain frame 31 are sequentially left on the filter plates 44 at the bottom position. Through the transmission of the filter plates 44, they move to the top position of the primary filtration mechanism 4, detach from the upper surface of the cooling oil, and are discharged from the cooling tank 3. This achieves primary filtration and cleaning of large particles of impurities in the cooling oil, preventing large particles of impurities from adhering to the aircraft parts during subsequent cooling of the aircraft parts and affecting the processing quality of the aircraft parts.

[0036] The secondary filtration mechanism 5 includes an outer filter cylinder 51, which is fixedly installed in the middle of the device base frame 1. A first sealing rotating member 52 is fixedly installed at the middle of the top and bottom of the outer filter cylinder 51. An inner filter cylinder 53 is provided inside the outer filter cylinder 51. An inlet pipe 531 is integrally formed at the top of the inner filter cylinder 53, and an outlet pipe 532 is integrally formed at the bottom of the inner filter cylinder 53. The inlet pipe 531 and the outlet pipe 532 are fixedly installed in the middle of the corresponding first sealing rotating member 52. By setting the first sealing rotating member 52, the inner filter cylinder 53, the inlet pipe 531, and the outlet pipe 532 can rotate at high speed and stably in the outer filter cylinder 51.

[0037] An oil-slowing chamber 501 is formed between the outer side of the filter outer cylinder 51 and the inner side of the filter inner cylinder 53. The filter inner cylinder 53 has a plurality of evenly distributed first filter through grooves 502. A second sealing rotating member 54 is fixedly installed on the top of the feed pipe 531. The feed pipe 55 is provided in the middle of the second sealing rotating member 54. A support frame 56 is fixedly installed on the outer side of the feed pipe 55. The support frame 56 is fixedly installed on the top of the filter outer cylinder 51. By setting the support frame 56, the feed pipe 55 is fixed to prevent the feed pipe 55 from rotating. The second sealing rotating member 54 is provided to ensure that the high-speed rotation of the feed pipe 531 is not affected.

[0038] An oil control valve 9 is fixedly installed at the bottom of the oil discharge hopper frame 31. The bottom of the oil control valve 9 and the top of the feed pipe 55 are fixedly installed. By setting the oil control valve 9, the oil control valve 9 is opened. The cooling oil after filtering large particles of impurities is introduced into the filter inner cylinder 53 through the feed pipe 55 and the feed pipe 531. With the high-speed rotation of the filter inner cylinder 53, the cooling oil undergoes secondary filtration under the action of centrifugation. Small particles of impurities are retained in the filter inner cylinder 53 and gradually enter the discharge pipe 532. The cooling oil is introduced into the oil buffer chamber 501 through multiple first filter channels 502 for buffering. The cooling oil undergoes secondary centrifugal filtration to prevent small particles of impurities from adhering to the aircraft parts during subsequent cooling of the aircraft parts and affecting the processing quality of the aircraft parts.

[0039] The bottom of the oil buffer chamber 501 is provided with an oil drain pipe 58, which is fixedly clamped in the outer filter cylinder 51. The end of the oil drain pipe 58 extends out of the outer wall of the outer filter cylinder 51. An oil guide pump 581 is fixedly installed at the end of the oil drain pipe 58 away from the outer filter cylinder 51. An L-shaped bend 582 is fixedly installed at the output end of the oil guide pump 581. An oil return pipe 32 is fixedly installed at the top of the cooling tank 3. The top end of the L-shaped bend 582 and the bottom end of the oil return pipe 32 are fixedly installed. By controlling the oil guide pump 581 to be turned on, the multi-stage filtered cooling oil buffered in the oil buffer chamber 501 flows into the cooling tank 3 through the oil drain pipe 58, the oil guide pump 581, the L-shaped bend 582, and the oil return pipe 32 for secondary recycling after filtration. This eliminates the need for frequent replacement of the cooling oil and improves the overall performance of the cooling device.

[0040] The bottom of the discharge pipe 532 extends out to the bottom of the filter outer cylinder 51. A crown gear 57 is fixedly sleeved on the bottom of the discharge pipe 532. A drive gear 571 is meshed with the side end of the crown gear 57. A drive shaft 572 is fixedly installed in the middle of the drive gear 571. The drive shaft 572 is rotatably installed at the bottom end of the filter outer cylinder 51. A first motor 573 is fixedly installed on the side of the bottom end of the filter outer cylinder 51 near the drive shaft 572. The drive end of the first motor 573 and the end of the drive shaft 572 are coaxially fixedly installed. The first motor 573 is turned on to drive the drive shaft 572 to rotate, thereby driving the drive gear 571 to rotate, which in turn drives the crown gear 57 and the discharge pipe 532 to rotate at high speed, thereby driving the filter inner cylinder 53 to rotate at high speed and stably in the filter outer cylinder 51.

[0041] The waste discharge assembly 6 includes a waste discharge hopper frame 61, which is fixedly installed on the top inner side of the discharge pipe 532. Small particles and impurities gradually entering the discharge pipe 532 enter the waste discharge hopper frame 61. A waste discharge pipe 62 is fixedly installed at the bottom of the waste discharge hopper frame 61, and the discharge pipe 532 extends from the bottom of the waste discharge pipe 62. A waste discharge cylinder 63 is slidably engaged in the waste discharge pipe 62. The upper surface of the waste discharge cylinder 63 is designed as a sealing structure, and the top of the waste discharge cylinder 63 has evenly distributed openings. Multiple waste discharge channels 601 are initially positioned at the top of the waste discharge pipe 62. A waste discharge cylinder 63 seals the bottom of the waste discharge hopper frame 61 to prevent small particles of impurities from entering the waste discharge hopper frame 61 and carrying away cooling oil. Two symmetrically distributed sliding strips 64 are fixedly installed on the outer wall of the waste discharge cylinder 63. A sliding groove 641, which cooperates with the sliding strips 64, is opened on the inner wall of the waste discharge pipe 62. The sliding strips 64 are slidably engaged in the sliding groove 641. A sliding strip 64 is slidably engaged in a sliding groove 641, facilitating the vertical movement of the waste discharge cylinder 63 within the waste discharge pipe 62. The waste discharge pipe 62 extends from the bottom of the waste discharge cylinder 63. A bearing 65 is fixedly fitted onto the bottom of the waste discharge cylinder 63, and a lifting frame 651 is fixedly mounted on the outer side of the bearing 65. A lifting cylinder 652 is fixedly mounted on the bottom end of the filter outer cylinder 51 near the lifting frame 651. The drive end of the lifting cylinder 652 is fixedly mounted to the lifting frame 651. The system is designed to allow for vertical movement of the waste discharge cylinder 63 within the waste discharge pipe 62. The bearing 65 is positioned so as not to affect the rotation of the waste discharge cylinder 63. After the cooling oil has undergone multi-stage filtration and all the filtered cooling oil has been recycled for reuse, the lifting cylinder 652 is activated to drive the lifting frame 651 and the bearing 65 to move the waste discharge cylinder 63 upward. Multiple waste discharge channels 601 move to the bottom of the waste discharge hopper frame 61, and small particulate impurities entering the waste discharge hopper frame 61 are automatically discharged through the multiple waste discharge channels 601, thus automatically cleaning the impurities and further improving the overall cooling effect.

[0042] The method of using the cooling device includes the following steps:

[0043] Step 1: Inject cooling oil into the cooling tank 3, place the heat-treated aircraft parts in the rack 8, control the linear electric rail 7 to move the aircraft parts horizontally, and control the lifting rod 71 to lower the aircraft parts. Place the heat-treated aircraft parts in the cooling tank 3 containing cooling oil for cooling. During cooling, a lot of impurities are generated. The impurities are suspended in the cooling oil and gradually deposited in the oil drain frame 31.

[0044] Step 2: Control the second motor 45 to drive the corresponding transmission roller 42 to rotate, thereby driving the transmission belt 43 to drive the transmission. The transmission belt 43 drives multiple filter plates 44 to drive. Since multiple second filter through slots 401 are provided, large particles of impurities that are gradually deposited in the oil drain frame 31 are sequentially left on the filter plates 44 at the bottom position. Through the transmission of the filter plates 44, they move to the top position of the primary filtration mechanism 4, detach from the upper surface of the cooling oil, and are discharged from the cooling tank 3 to perform primary filtration and cleaning of large particles of impurities in the cooling oil.

[0045] Step 3: Control the first motor 573 to drive the drive shaft 572 to rotate, thereby driving the drive gear 571 to rotate, which in turn drives the crown gear 57 and the discharge pipe 532 to rotate at high speed, thereby driving the inner filter cylinder 53 to rotate at high speed and stably in the outer filter cylinder 51. Control the opening of the oil control valve 9. The cooling oil after filtering large particles of impurities is introduced into the inner filter cylinder 53 through the feed pipe 55 and the feed pipe 531. With the high speed rotation of the inner filter cylinder 53, the cooling oil undergoes secondary filtration under the action of centrifugation. Small particles of impurities are retained in the inner filter cylinder 53 and gradually enter the discharge pipe 532. The cooling oil is introduced into the slow oil chamber 501 through multiple first filter channels 502 for buffering, and the cooling oil undergoes secondary centrifugal filtration.

[0046] Step 4: Control the start of the oil pump 581. The multi-stage filtered cooling oil buffered in the oil buffer chamber 501 flows into the cooling tank 3 through the oil drain pipe 58, the oil pump 581, the L-shaped bend pipe 582, and the return oil pipe 32 for secondary recycling after filtration. There is no need to frequently replace the cooling oil.

[0047] Step 5: Small particulate impurities gradually enter the discharge pipe 532 and enter the waste discharge hopper frame 61. After the cooling oil is filtered through multiple stages and all the filtered cooling oil is recycled for reuse, the lifting cylinder 652 is activated to drive the lifting frame 651 and bearing 65 to move the waste discharge cylinder 63 upward. Multiple waste discharge channels 601 move to the bottom of the waste discharge hopper frame 61, and the small particulate impurities entering the waste discharge hopper frame 61 are automatically discharged through the multiple waste discharge channels 601, thus automatically cleaning the impurities.

8. A cooling device for heat treatment of aircraft parts according to claim 7, characterized in that: The method of using the cooling device includes the following steps: Step 1: Inject cooling oil into the cooling tank (3), place the heat-treated aircraft parts in the shelf (8), control the linear electric rail (7) to control the translation of the aircraft parts, and open the lifting rod (71) to control the descent of the aircraft parts. Place the heat-treated aircraft parts in the cooling tank (3) containing cooling oil for cooling. During cooling, a lot of impurities are generated. The impurities are suspended in the cooling oil and gradually deposited in the oil drain frame (31). Step 2: Control the second motor (45) to drive the corresponding transmission roller (42) to rotate, thereby driving the transmission belt (43) to drive. The transmission belt (43) drives multiple filter plates (44) to drive. Since multiple second filter slots (401) are provided, large particles of impurities that are gradually deposited in the oil drain frame (31) are placed on the filter plates (44) at the bottom position in sequence. Through the transmission of the filter plates (44), they move to the top position of the primary filtration mechanism (4), detach from the upper surface of the cooling oil, and are discharged from the cooling tank (3) to perform primary filtration and cleaning of large particles of impurities in the cooling oil. Step 3: Control the first motor (573) to drive the drive shaft (572) to rotate, thereby driving the drive gear (571) to rotate, which in turn drives the crown gear (57) and the discharge pipe (532) to rotate at high speed, thereby driving the filter inner cylinder (53) to rotate at high speed and stably in the filter outer cylinder (51). Control the opening of the oil control valve (9), and the cooling oil after filtering large particles of impurities is introduced into the filter inner cylinder (53) through the feed pipe (55) and feed pipe (531). With the high speed rotation of the filter inner cylinder (53), the cooling oil undergoes secondary filtration under the action of centrifugation. Small particles of impurities are left in the filter inner cylinder (53) and gradually enter the discharge pipe (532). The cooling oil is introduced into the slow oil chamber (501) through multiple first filter through slots (502) for buffering, and the cooling oil undergoes secondary centrifugal filtration. Step 4: Control the start of the oil pump (581). The multi-stage filtered cooling oil buffered in the oil buffer chamber (501) flows into the cooling tank (3) through the oil drain pipe (58), oil pump (581), L-shaped bend pipe (582), and return oil pipe (32) for secondary recycling after filtration. There is no need to frequently replace the cooling oil. Step 5: Small particulate impurities gradually enter the discharge pipe (532) and enter the waste discharge hopper frame (61). After the cooling oil is filtered through multiple stages and all the filtered cooling oil is recycled for reuse, the lifting cylinder (652) is activated to drive the lifting frame (651) and bearing (65) to move the waste discharge cylinder (63) upward. Multiple waste discharge channels (601) move to the bottom of the waste discharge hopper frame (61). The small particulate impurities entering the waste discharge hopper frame (61) are automatically discharged through multiple waste discharge channels (601) to automatically clean the impurities.
