Description

Technical Field

[0001] The invention belongs to the technical field of bearing production and processing, and specifically relates to a sealing copper sleeve and a preparation device thereof. Background Art

[0002] Sealed copper sleeves, also known as bronze bearing sleeves or self-lubricating bearing sleeves, are a type of bearing component made of copper alloy (such as tin bronze, aluminum bronze, etc.) as the main material. They are usually used in rotating or sliding motion parts that require wear resistance, corrosion resistance and the ability to withstand a certain load. Sealed copper sleeves are often used for sealing and bearing support between shafts and holes in the fields of water pumps, ships, chemical machinery, heavy machinery, hydraulic equipment, etc. They can not only play a sealing role, but also serve as a bearing surface to reduce direct metal-to-metal friction and improve the working efficiency and reliability of the equipment.

[0003] After searching, it was found that a Chinese patent with the authorization announcement number "CN117444732B" disclosed an automatic copper sleeve grinding device and its use method, which includes a bottom plate, an arc plate arranged on the bottom plate, and a copper sleeve located in the arc plate; it also includes a power mechanism for positioning the copper sleeve and driving the copper sleeve to rotate, a grinding sheet arranged on the inner peripheral wall of the arc plate and in contact with the right end face of the copper sleeve, and a grinding mechanism; the grinding mechanism includes a support plate c, an outer grinding roller, an inner grinding roller and an end face grinding roller arranged on the support plate c, and a displacement assembly that drives the support plate c to move horizontally; in the grinding state, the outer grinding roller contacts the outer peripheral surface of the copper sleeve, the inner grinding roller contacts the inner peripheral surface of the copper sleeve, and the end face grinding roller contacts the left end face of the copper sleeve.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. Through this device, air pressure provides thrust to complete automatic grinding, changing the use of motors for driving in traditional processing, and avoiding the need to change the driving mechanism at any time for digital grinding when processing and polishing the self-lubricating copper sleeve body with different inner wall shapes.

[0023] 2. Through this device, when the pressure plate slides back to the front of the air outlet, due to the leakage of part of the air from the pressure relief hole, the pressure in the pressure groove is less than the normal atmospheric pressure when the pressure plate slides to the original position. The pressure difference between the inside and outside of the pressure groove forms a thrust, pushing the first push rod back to fit the inner wall of the first air pressure push groove, and pushing the connecting push rod back into the connected air pressure groove, resetting the first grinder and the second grinder, avoiding direct contact between the first grinder and the second grinder and the main body of the self-lubricating copper sleeve during the next grinding.

[0024] 3. Through this device, when the pressure reaches more than two atmospheres, the thrust exerted by the air pressure on the pressure relief cylinder pushes the connecting air hole opened at the upper end of the pressure relief cylinder to the pressure relief air hole. At this time, part of the air in the pressurized tank leaks out from the pressure relief air hole to reduce the overall pressure in the pressurized tank. When the air leaks out and the pressure in the pressurized tank drops below two atmospheres, the thrust of the resistance spring will dislocate the pressure relief air hole and the connecting air hole again to maintain a higher pressure in the fitting mechanism while avoiding excessive pressure, which will cause the first grinder and the second grinder to be excessively squeezed and damaged.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0038] See also Figure 1-Figure 10 , the present invention provides the following technical solutions:

[0039] A sealing copper sleeve preparation device, comprising:

[0040] Processing base 1;

[0041] The mounting cylinder 2 is rotatably connected to the upper end of the processing base 1;

[0042] A self-lubricating copper sleeve body 3, which is arranged in the installation tube 2;

[0043] The laminating mechanism includes a pressure cylinder 4, a pressure groove 5, a pressure plate 6, a pressure push rod 7, an air outlet 8, a connecting air hole 9, a first air pressure push groove 10, a first grinder 11, a first push rod 12 and a contact block 38. The pressure cylinder 4 is arranged on the upper side of the processing base 1, the pressure groove 5 is opened at the lower end of the pressure cylinder 4, the pressure push rod 7 is slidably connected to the pressure groove 5, the pressure plate 6 is fixedly connected to the upper end of the pressure push rod 7 and slides in the pressure groove 5, the air outlet 8 It is opened on the inner wall of one side of the pressurizing groove 5, and the communicating air hole 9 is opened on the upper inner wall of the pressurizing groove 5. The first air pressure push groove 10 is opened on one side end of the pressure cylinder 4 and is connected with the pressurizing groove 5. The first push rod 12 is slidably connected in the first air pressure push groove 10. The first grinder 11 is arranged on one side of the pressure cylinder 4. The first push rod 12 is fixed to the first grinder 11. The contact block 38 is fixedly connected to the upper end of the mounting cylinder 2, and the lower end of the pressurizing push rod 7 contacts the contact block 38.

[0044] In a specific embodiment of the present invention, the mounting cylinder 2 is arranged at the upper end of the processing base 1 but is not fixed to the processing base 1, and is used to fix the self-lubricating copper sleeve body 3. The self-lubricating copper sleeve body 3 is cast by a metal mold, which can provide higher dimensional accuracy and surface finish, and the internal quality of the casting is better. After the production is completed, the surface of the self-lubricating copper sleeve body 3 is subjected to more refined processing and polishing. The communicating air hole 9 is a ventilated air hole to connect the first air pressure push groove 10 and the pressurizing groove 5. One side end of the first air pressure push groove 10 is blocked by the first push rod 12. The pressurizing plate 6 slides in the pressurizing groove 5 and separates the upper and lower parts of the space of the pressurizing groove 5. When no polishing work is performed, the pressurizing plate 6 is located in the pressurizing groove 5 due to its own gravity. The first push rod 12 is also close to the inner wall of one side of the first air pressure push groove 10. When the inner and outer surfaces of the self-lubricating copper sleeve body 3 need to be polished, the self-lubricating copper sleeve body 3 is placed in the installation tube 2. The rubber material groove in the installation tube 2 increases the friction force on the self-lubricating copper sleeve body 3, so that the installation tube 2 will not shift. The driving mechanism drives the pressure cylinder 4 to move downward. As the pressure cylinder 4 moves downward, the lower end of the pressure push rod 7 contacts the contact block 38, and the contact block 38 resists the lower end of the pressure push rod 7, so that the pressure plate 6 slides toward the upper end of the pressure groove 5. Before the pressure plate 6 is lifted to the upper end of the air outlet 8 in the pressure groove 5, the air in the pressure groove 5 circulates through the air outlet 8, so that the internal air pressure of the pressure groove 5 is not The pressure plate 6 will change, and when the pressure plate 6 slides to the upper end of the air outlet 8, the upper end of the pressure groove 5 is in a sealed state, and the air pressure in the pressure groove 5 is gradually increased with the sliding of the pressure plate 6. The high pressure in the pressure groove 5 pushes the first push rod 12 to slide outward. At this time, the grinding end of the first grinder 11 also slides to the inner wall of the self-lubricating copper sleeve body 3. The first grinder 11 is driven by the first air pressure push groove 10 to move to the inner wall of the self-lubricating copper sleeve body 3. The driving mechanism drives the pressure cylinder 4 to continue to descend, so that the first grinder 11 polishes the inner wall of the self-lubricating copper sleeve body 3 from top to bottom, and as the pressure cylinder 4 moves downward, the air in the pressure groove 5 is kept at a relatively high pressure, and the thrust of the pressure causes the first grinder 11 to The grinding end is always close to the inner wall of the self-lubricating copper sleeve body 3, and when polishing and grinding self-lubricating copper sleeve bodies 3 of different models, if the inner diameters are different or there are concave and convex parts on the inner wall of the self-lubricating copper sleeve body 3, the convex parts push the first grinder 11 to overcome the thrust of the air pressure on the first push rod 12 and push the first grinder 11 inward for a distance, so that the device can accurately grind and polish the inner wall of the self-lubricating copper sleeve body 3 with different inner wall shapes, and complete the automatic grinding by providing thrust through air pressure, changing the use of motors for driving in traditional processing, and avoiding the need to change the driving mechanism at any time to perform digital grinding and automatic grinding trajectory when processing and polishing the self-lubricating copper sleeve body 3 with different inner wall shapes.

[0045] For details, please refer to Figure 1-Figure 10The upper end of the pressure cylinder 4 is fixedly connected with a connecting arc plate 13, the lower end of the connecting arc plate 13 is fixedly connected with an external grinding block 14, and a second grinder 15 is provided on one side of the external grinding block 14.

[0046] In this embodiment: the first grinder 11 is used to grind the inner wall of the self-lubricating copper sleeve body 3, the second grinder 15 is arranged on the outside of the self-lubricating copper sleeve body 3 to grind and polish the outer surface of the self-lubricating copper sleeve body 3, the pressure cylinder 4 is used to support the first grinder 11, the outer grinding block 14 is used to support the second grinder 15, the connecting arc plate 13 connects and fixes the pressure cylinder 4 and the outer grinding block 14, the pressure cylinder 4, the connecting arc plate 13 and the outer grinding block 14 are in a "bow" shape, and the inner and outer surfaces of the self-lubricating copper sleeve body 3 are arranged between the second grinder 15 and the first grinder 11 for polishing.

[0047] For details, please refer to Figure 1-Figure 10 A connecting air pressure groove 16 is opened at the upper end of the outer grinding block 14, and a connecting air pipe 19 is fixedly connected to the upper inner wall of the connecting air pressure groove 16 and the upper inner wall of the connecting air hole 9. A pushing plate 17 is slidably connected in the connecting air pressure groove 16, and a connecting push rod 18 is fixedly connected to one side end of the pushing plate 17, and the connecting push rod 18 is fixedly connected to the second grinder 15.

[0048] In this embodiment: the lower end of the connecting air hole 9 is connected to the first air pressure push groove 10, and the upper end is connected to the connecting air pipe 19. The connecting air pipe 19 is used to pressurize the connecting air pressure groove 16. The push plate 17 and the pressure plate 6 are both sealing slide plates. When the air pressure in the pressurized groove 5 is enhanced, the air pressure in the connecting air pressure groove 16 is also enhanced due to the connection of the connecting air pipe 19. The air pressure in the connecting air pressure groove 16 pushes the connecting push rod 18 to slide outward, so that the grinding end of the second grinder 15 contacts the outer surface of the self-lubricating copper sleeve body 3 and grinds.

[0049] For details, please refer to Figure 1-Figure 10 A pressure relief groove 20 is provided on the inner wall of one side of the pressurizing groove 5, a spring groove 21 is provided on the inner wall of one side of the pressure relief groove 20, a pressure relief cylinder 23 is slidably connected in the pressure relief groove 20, and a resistance spring 24 is fixedly connected to the inner wall of one side of the spring groove 21 and one side end of the pressure relief cylinder 23.

[0050] In this embodiment: the resistance spring 24 and the pressure relief cylinder 23 are used to adjust the pressure in the pressurized groove 5. When the pressurized groove 5 is at normal pressure, the resistance spring 24 pushes the pressure relief cylinder 23 against the inner wall of the pressure relief groove 20. When the pressure in the pressurized groove 5 increases to a certain level, the pressure in the pressurized groove 5 pushes the pressure relief cylinder 23 to slide to one side of the pressure relief groove 20 to increase the space size of the sealing part in the pressurized groove 5, thereby avoiding excessive pressure in the pressurized groove 5, which will cause excessive thrust on the first grinder 11 and the second grinder 15, resulting in excessive extrusion and damage to the grinding ends of the first grinder 11 and the second grinder 15.

[0051] For details, please refer to Figure 1-Figure 10 An adjusting air hole 22 is opened on one inner wall of the spring groove 21 , a pressure relief air hole 25 is opened on the upper inner wall of the pressure relief groove 20 , and a connecting air hole 26 is opened on the upper inner wall of the pressure relief cylinder 23 .

[0052] In this embodiment: when the pressure cylinder 4 moves downward and the pressure plate 6 slides to the upper end of the air outlet 8, the pressure in the pressure groove 5 is a normal atmospheric pressure. When the pressure plate 6 continues to slide upward, the pressure in the pressure groove 5 continues to increase. The pressure in the pressure groove 5 applies thrust to the pressure relief cylinder 23, the first push rod 12 and the push plate 17 respectively. When the pressure reaches more than two atmospheres, the thrust applied by the air pressure on the pressure relief cylinder 23 pushes the connecting air hole 26 opened at the upper end of the pressure relief cylinder 23 to the pressure relief air hole 25. At this time, part of the air in the pressure groove 5 leaks out from the pressure relief air hole 25 to reduce the overall pressure in the pressure groove 5. When the air leaks out and the pressure in the pressure groove 5 drops below two atmospheres, the thrust of the resistance spring 24 dislocates the pressure relief air hole 25 and the connecting air hole 26 again to maintain a higher pressure in the fitting mechanism. At the same time, excessive pressure is avoided, which causes the first grinder 11 and the second grinder 15 to be damaged by excessive extrusion. After the grinding is completed, the driving mechanism drives the pressure cylinder 4 to move upward. When the pressure plate 6 slides back to the front of the air outlet 8, a part of the air is leaked out of the pressure relief hole 25. Therefore, when the pressure plate 6 slides to its original position, the pressure in the pressure groove 5 is less than a normal atmospheric pressure. The internal and external pressure difference of the pressure groove 5 forms a thrust, pushing the first push rod 12 back to fit the inner wall of the first air pressure push groove 10, and pushing the connecting push rod 18 back into the connecting air pressure groove 16, resetting the first grinder 11 and the second grinder 15. When performing the next grinding, the first grinder 11 and the second grinder 15 can be pushed toward the inner and outer surfaces of the self-lubricating copper sleeve body 3 again until they contact the surface of the self-lubricating copper sleeve body 3 for grinding.

[0053] For details, please refer to Figure 1-Figure 10 A rotation groove 27 is formed at the upper end of the processing base 1 , a support block 40 is rotatably connected in the rotation groove 27 , and a driven gear 28 is fixedly connected to the circumferential surface of the support block 40 .

[0054] In this embodiment: the driven gear 28 is connected to the driving mechanism to drive the self-lubricating copper sleeve body 3 to rotate during grinding, the support block 40 is fixed to the lower end of the mounting tube 2, and the lower end of the support block 40 rotates in the rotating groove 27. The positions of the first grinder 11 and the second grinder 15 during grinding are fixed. During grinding, the first grinder 11 and the second grinder 15 gradually move downward, and the driving mechanism drives the driven gear 28 to rotate, and then drives the self-lubricating copper sleeve body 3 to rotate during grinding, so as to grind the inner and outer surfaces of the self-lubricating copper sleeve body 3 as a whole in all directions.

[0055] For details, please refer to Figure 1-Figure 10 The upper end of the processing base 1 is fixedly connected to a driving motor 29, and a limited rotation groove 39 is provided on the lower inner wall of the rotating groove 27. A driving gear 30 is rotatably connected in the limited rotation groove 39, and the driving gear 30 is meshed with the driven gear 28. The upper end of the processing base 1 is fixedly connected to a driving motor 29, and the output end of the driving motor 29 is fixedly connected to the driving gear 30.

[0056] In this embodiment: a fixing sleeve is provided on the surface of the driving motor 29 to fix the driving motor 29, and the output end of the driving motor 29 passes through the upper inner wall of the rotating groove 27 to be connected with the driving gear 30. When grinding, the driving motor 29 drives the driving gear 30 to rotate, and drives the self-lubricating copper sleeve body 3 to rotate through the driven gear 28, so as to perform all-round grinding on the inner and outer surfaces of the self-lubricating copper sleeve body 3.

[0057] For details, please refer to Figure 1-Figure 10 A first limiting groove 31 is provided on one side surface of the outer grinding block 14, a first limiting slider 32 is fixedly connected to the lower end of the second grinder 15, the first limiting slider 32 slides in the first limiting groove 31, a second limiting groove 33 is provided on one side end of the pressure cylinder 4, a second limiting slider 34 is fixedly connected to one side end of the first grinder 11, and the second limiting slider 34 slides in the second limiting groove 33.

[0058] In this embodiment: the first grinder 11 and the second grinder 15 are respectively connected to the pressure cylinder 4 and the outer grinding block 14 through a limiting assembly, the second limiting slider 34 is fixed to one side end of the first grinder 11 and slides in the second limiting slide groove 33 to limit the sliding direction of the first grinder 11, so that the first grinder 11 can only slide along the moving direction of the first push rod 12, and similarly, the first limiting slider 32 at the lower end of the second grinder 15 slides in the first limiting slide groove 31 to limit the sliding direction of the second grinder 15, so that the second grinder 15 can only move following the sliding direction of the connecting push rod 18.

[0059] For details, please refer to Figure 1-Figure 10 The upper end of the processing base 1 is fixedly connected with a lifting machine 35 , and one side end of the lifting machine 35 is fixedly connected with a lifting block 36 , and the lifting block 36 is fixedly connected to the connecting arc plate 13 .

[0060] In this embodiment: the lifting machine 35 is used to lift and lower the pressure cylinder 4, and the lifting end of the lifting machine 35 is connected to the connecting arc plate 13 through the lifting block 36. When grinding, after the self-lubricating copper sleeve body 3 is fixed in the installation cylinder 2, the lifting machine 35 drives the connecting arc plate 13 to move downward to grind the inner and outer surfaces of the self-lubricating copper sleeve body 3.

[0061] For details, please refer to Figure 1-Figure 10 The circumferential surfaces of the pressure plate 6 , the push plate 17 and the lower inner wall of the pressure groove 5 are all fixedly connected with a sealing ring 37 .

[0062] In this embodiment: the sealing ring 37 is respectively fixed on the surface of the push plate 17, the pressure plate 6 and the connecting end of the pressure push rod 7 and the pressure groove 5, and is used to seal the high-pressure part to prevent air leakage from causing a decrease in thrust on the first grinder 11 and the second grinder 15.

[0063] It should be noted that the first grinder 11, the second grinder 15, the lifting machine 35 and the driving motor 29 used in the device are all existing technologies and will not be described in detail here.

[0064] Working principle and use process of the present invention: the mounting cylinder 2 is arranged at the upper end of the processing base 1 but is not fixed to the processing base 1, and is used to fix the self-lubricating copper sleeve body 3. The self-lubricating copper sleeve body 3 is cast by metal mold, which can provide higher dimensional accuracy and surface finish, and the internal quality of the casting is better. After the production is completed, the surface of the self-lubricating copper sleeve body 3 is processed and polished more finely, and the connecting air hole 9 is a ventilated air hole to connect the first air pressure push groove 10 and the pressurizing groove 5. One side end of the first air pressure push groove 10 is blocked by the first push rod 12. The pressurizing plate 6 slides in the pressurizing groove 5 and separates the upper and lower parts of the space of the pressurizing groove 5. When no polishing work is performed, the pressurizing plate 6 is located in the pressurizing groove due to its own gravity. 5, and the first push rod 12 is also close to the inner wall of one side of the first air pressure push groove 10. When it is necessary to grind the inner and outer surfaces of the self-lubricating copper sleeve body 3, the self-lubricating copper sleeve body 3 is placed in the installation cylinder 2. The rubber material groove in the installation cylinder 2 increases the friction force on the self-lubricating copper sleeve body 3, so that the installation cylinder 2 will not shift. The driving mechanism drives the pressure cylinder 4 to move downward. As the pressure cylinder 4 moves downward, the lower end of the pressure push rod 7 contacts the contact block 38, and the contact block 38 abuts against the lower end of the pressure push rod 7, so that the pressure plate 6 slides toward the upper end of the pressure groove 5. Before the pressure plate 6 is lifted to the upper end of the air outlet 8 in the pressure groove 5, the air in the pressure groove 5 circulates through the air outlet 8, so that the internal air pressure of the pressure groove 5 The pressure plate 6 slides to the upper end of the air outlet 8, and the upper end of the pressure groove 5 is in a sealed state, and the air pressure in the pressure groove 5 is gradually increased with the sliding of the pressure plate 6. The high pressure in the pressure groove 5 pushes the first push rod 12 to slide outward. At this time, the grinding end of the first grinder 11 also slides to the inner wall of the self-lubricating copper sleeve body 3. The first grinder 11 is driven by the first air pressure push groove 10 to move to the inner wall of the self-lubricating copper sleeve body 3. The driving mechanism drives the pressure cylinder 4 to continue to descend, so that the first grinder 11 polishes the inner wall of the self-lubricating copper sleeve body 3 from top to bottom, and as the pressure cylinder 4 moves downward, the air in the pressure groove 5 is kept at a relatively high pressure, and the thrust of the pressure causes the first grinder 11 to The grinding end is always close to the inner wall of the self-lubricating copper sleeve body 3, and when polishing and grinding self-lubricating copper sleeve bodies 3 of different models, if the inner diameters are different or there are concave and convex parts on the inner wall of the self-lubricating copper sleeve body 3, the convex parts push the first grinder 11 to overcome the thrust of the air pressure on the first push rod 12 and push the first grinder 11 inward for a distance, so that the device can accurately grind and polish the inner wall of the self-lubricating copper sleeve body 3 with different inner wall shapes, and complete the automatic grinding by providing thrust through air pressure, changing the use of motors for driving in traditional processing, and avoiding the need to change the driving mechanism at any time to perform digital grinding and automatic grinding trajectory when processing and polishing the self-lubricating copper sleeve body 3 with different inner wall shapes.
