Description

Technical Field

[0001] This invention relates to the field of bearing copper sleeve processing technology, specifically a precision assembled self-lubricating bearing copper sleeve. Background Technology

[0002] Precision-fitted self-lubricating bearing bushes are widely used in industrial automation, machine tools, and other fields due to their advantages such as self-lubrication, wear resistance, and high precision. Their self-lubricating function mainly relies on graphite particles embedded and fixed on the side surface of the bushing body. During the graphite particle embedding and fixing process, due to the influence of the processing technology, excess material can easily remain on the surface of the bushing body. If this is not cleaned in time, it will lead to a decrease in the subsequent assembly accuracy of the bushing, and may also affect the self-lubricating effect or even damage the mating shaft components due to the excess material falling off during use.

[0003] In existing technologies, the grinding of excess material in copper bushings is mostly done manually using handheld grinding equipment, which is not only inefficient but also makes it difficult to guarantee grinding accuracy. Although some automated grinding equipment can improve efficiency, the clamping and support structure of the copper bushing is not reasonably designed and cannot flexibly switch the fixing method according to grinding needs. This can easily lead to problems such as displacement and deformation of the copper bushing during grinding, affecting the processing quality of the copper bushing. Therefore, we propose a precision combined self-lubricating bearing copper bushing. Summary of the Invention

[0004] The purpose of this invention is to provide a precision combined self-lubricating bearing copper sleeve to solve the problems mentioned in the background art, such as low grinding efficiency of excess material after graphite particle embedding and fixing in existing copper sleeves, and lack of flexible and adaptable clamping and support structures. To achieve the above objective, this invention provides the following technical solution: a precision combined self-lubricating bearing copper sleeve, including a mounting bracket; The adjustment component includes a mounting slot on one side of a mounting frame. A rotating slot is located on one side of the mounting frame. A rotating rod is rotatably connected to the interior of the rotating slot via a bearing. A rotating disk is fixedly connected to one end of the rotating rod. Four adjustment slots are located on one side of the rotating disk and are arranged in a circular array. Sliding rods are slidably connected to the interior of each of the four adjustment slots. When using this device, through the coordinated operation of the power component, adjustment component, and support component, the clamping and support methods for the copper sleeve can be flexibly switched according to the actual needs of copper sleeve grinding. Whether it is necessary to grind excess material remaining on the inner wall of the copper sleeve or to treat overflowing edges and burrs on the outer side of the copper sleeve, adaptation and fixation can be achieved through the linkage between the components. This effectively solves the problem of traditional grinding equipment having a single fixing method and being unable to meet the needs of different grinding scenarios, greatly improving the flexibility and applicability of grinding operations, and adapting to the processing needs of copper sleeves of various specifications. A power assembly, comprising a mounting bracket fixedly connected inside a mounting slot, with a motor fixedly connected to the top of the mounting bracket.

[0005] More preferably, the power assembly further includes a first gear, which is fixedly connected to the side surface of the rotating rod, is disposed inside the mounting groove, and a second gear is disposed at the bottom of the first gear.

[0006] More preferably, the other side of the second gear is fixedly connected to the transmission end of the motor, the outer side of the second gear is meshed with the outer side of the first gear, and a guide component is provided on one side of the mounting bracket.

[0007] More preferably, the guide assembly includes a support platform, and a limiting groove is formed on the other side of the support platform. The interior of the limiting groove is adapted to the side surface of the rotating disk, and four sliding grooves are formed inside the limiting groove and are distributed in a circular array.

[0008] More preferably, four sliding grooves are provided on one side of the support platform. The interior of each sliding groove is fixedly connected to the interior of the first sliding groove. A support assembly is provided inside each sliding groove. The structural design of the sliding groove and the limiting groove in the guide assembly provides stable guidance and limiting for the movement trajectory of the support assembly and the rotation range of the rotating disk. The sliding groove can limit the movement direction of the support plate and the mounting block, preventing them from deviating during adjustment.

[0009] More preferably, the support assembly includes four support plates, each of which is fixedly connected to one end of one of four sliding rods and slidably connected to the outside of the support plates and the inside of the sliding groove. Each of the four support plates has a mounting block fixedly connected to one side.

[0010] More preferably, the outer side of the mounting block is slidably connected to the inside of the second groove, a mounting plate is fixedly connected to one side of the mounting block, and a support rod is fixedly connected to one side of the mounting plate.

[0011] In a further preferred embodiment, a copper sleeve body is sleeved on the outer side of the support rod. The side surface of the copper sleeve body is provided with several fitting grooves, and graphite particles are fixedly connected inside the several fitting grooves respectively. This reduces the scrap rate of the copper sleeve processing, while ensuring the surface quality of the copper sleeve, laying a good foundation for subsequent assembly and use, and indirectly improving the service life and self-lubricating effect stability of the copper sleeve in actual applications.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: In this invention, when using the device, the coordinated operation of the power component, adjustment component, and support component allows for flexible switching between clamping and supporting methods for the copper sleeve body according to the actual needs of copper sleeve grinding. Whether it is necessary to grind the excess material remaining on the inner wall of the copper sleeve or to treat the overflowing edges and burrs on the outer side of the copper sleeve, the components can work together to achieve adaptive fixing. This effectively solves the problem that traditional grinding equipment has a single fixing method and cannot meet the needs of different grinding scenarios, greatly improving the flexibility and applicability of grinding operations and adapting to the processing needs of copper sleeves of various specifications.

[0013] In this invention, during the grinding process, the design of the sliding groove and limiting groove in the guide assembly provides stable guidance and limiting for the movement trajectory of the support assembly and the rotation range of the rotating disk. The sliding groove restricts the movement direction of the support plate and mounting block, preventing them from shifting during adjustment; the limiting groove prevents radial wobbling when the rotating disk rotates, further improving the accuracy of the entire adjustment action. This design ensures that the copper sleeve body maintains a stable position during the grinding process, effectively reducing the situation of incomplete or excessive grinding of excess material, reducing the scrap rate of the copper sleeve, and ensuring the surface quality of the copper sleeve. This lays a good foundation for subsequent assembly and use, indirectly improving the service life and self-lubricating stability of the copper sleeve in practical applications.

[0016] 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.

[0017] Please see Figures 1-6 The present invention provides a technical solution: a precision combined self-lubricating bearing copper sleeve, including a mounting bracket 1; Adjustment component 2 includes a mounting slot 201 located on one side of the mounting frame 1. A rotating slot 202 is located on one side of the mounting frame 1. A rotating rod 203 is rotatably connected to the interior of the rotating slot 202 via a bearing. A rotating disk 204 is fixedly connected to one end of the rotating rod 203. Four adjustment slots 205 are located on one side of the rotating disk 204 and are arranged in a circular array. Sliding rods 206 are slidably connected to the interior of each of the four adjustment slots 205. When the rotating rod 203 rotates, it synchronously drives the rotating disk 204. The support platform 401 rotates within the limiting groove 402, and the four adjusting grooves 205 on the rotating disk 204 rotate with the rotating disk 204, forcing the slide rod 206 to slide within the adjusting groove 205. At the same time, the slide rod 206 drives the support plate 501 to slide within the first sliding groove 403. When the support plate 501 slides, it pushes the mounting block 502 to move along the second sliding groove 404. The mounting block 502 drives the support rod 504 to move synchronously through the mounting plate 503 until the inner side of the four support rods 504 is tightly fitted with the outer side of the copper sleeve body 6, thereby achieving clamping of the outer side of the copper sleeve body 6.

[0018] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the power assembly 3 includes a fixed frame 301, which is fixedly connected to the inside of the mounting groove 201. A motor 302 is fixedly connected to the top of the fixed frame 301. The power assembly 3 also includes a gear 303, which is fixedly connected to the side surface of the rotating rod 203. The gear 303 is located inside the mounting groove 201. A gear 304 is located at the bottom of the gear 303. The other side of the gear 304 is fixedly connected to the transmission end of the motor 302. The outer side of the gear 304 meshes with the outer side of the gear 303. A guide assembly 4 is provided on one side of the mounting frame 1. In use, the copper sleeve body 6 is first fitted onto the outer side of the four support rods 504. The motor 302 is started, and the transmission end of the motor 302 drives the gear 304 to rotate. Because the gear 304 meshes with the gear 303, the gear 303 rotates with the gear 304 and drives the rotating rod 203 to rotate stably in the rotating groove 202.

[0019] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the guide component 4 includes a support platform 401. A limiting groove 402 is formed on the other side of the support platform 401. The interior of the limiting groove 402 is adapted to the side surface of the rotating disk 204. The interior of the limiting groove 402 is provided with four sliding grooves 403 arranged in a circular array. Four sliding grooves 404 are formed on one side of the support platform 401. The interior of the sliding grooves 404 is fixedly connected to the interior of the sliding grooves 403. A support component 5 is provided inside the sliding grooves 404. The sliding grooves 403, sliding grooves 404 and limiting groove 402 of the guide component 4 respectively guide and limit the support plate 501, the mounting block 502 and the rotating disk 204, ensuring stable and accurate adjustment. At the same time, the graphite particles 8 on the copper sleeve body 6 can achieve self-lubrication function in subsequent use.

[0020] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the support assembly 5 includes four support plates 501. The four support plates 501 are respectively fixedly connected to one end of four sliding rods 206, and the outer side of each support plate 501 is slidably connected to the inside of the first sliding groove 403. Mounting blocks 502 are respectively fixedly connected to one side of each of the four support plates 501. The outer side of each mounting block 502 is slidably connected to the inside of the second sliding groove 404. Mounting plates 503 are fixedly connected to one side of each mounting block 502. Support rods 504 are fixedly connected to one side of each mounting plate 503. A copper sleeve body 6 is sleeved on the outer side of each support rod 504. The side surface of the body 6 is provided with several fitting grooves 7, and graphite particles 8 are fixedly connected inside the fitting grooves 7 respectively. The slide rod 206 drives the support plate 501 to slide in the first slide groove 403. When the support plate 501 slides, it pushes the mounting block 502 to move along the second slide groove 404. The mounting block 502 drives the support rod 504 to move synchronously through the mounting plate 503 until the inner side of the four support rods 504 is tightly fitted with the outer side of the copper sleeve body 6, thereby clamping the outer side of the copper sleeve body 6. At this time, the grinding equipment can be inserted into the interior of the copper sleeve body 6 to grind the inner wall.

[0021] The method of use and advantages of this invention: The working process of this precision combined self-lubricating bearing copper sleeve during use is as follows: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, in use, first, the copper sleeve body 6 is fitted onto the outside of the four support rods 504. Then, the motor 302 is started. The transmission end of the motor 302 drives the gear 2 304 to rotate. Since the gear 2 304 meshes with the gear 1 303, the gear 1 303 rotates with the gear 2 304 and drives the rotating rod 203 to rotate stably in the rotating groove 202. When the rotating rod 203 rotates, it synchronously drives the rotating disk 204 to rotate in the limiting groove 402 of the support platform 401. The four adjusting grooves 205 on the rotating disk 204 rotate with the rotating disk 204, forcing the sliding rod 206 to slide in the adjusting groove 205. At the same time, the sliding rod 206 drives the support plate 501 to slide in the sliding groove 1 403. When the support plate 501 slides, it pushes the mounting block 502 to move along the sliding groove 2 404. The mounting block 502 drives the support rod 504 to move synchronously through the mounting plate 503 until the inner side of the four support rods 504 is tightly fitted with the outer side of the copper sleeve body 6. The fitting achieves clamping of the outer side of the copper sleeve body 6, at which point the grinding equipment can extend into the interior of the copper sleeve body 6 for inner wall grinding. If grinding of the outer side of the copper sleeve body 6 is required, the motor 302 is started in reverse, causing the rotating disk 204 to rotate in the opposite direction. The slide rod 206 drives the support plate 501, mounting block 502, and mounting plate 503 to move in the opposite direction, thereby causing the four support rods 504 to move towards the center of the copper sleeve body 6 until the outer side of the support rods 504 is in close contact with the inner side of the copper sleeve body 6, completing the support of the interior of the copper sleeve body 6. At this point, the grinding equipment can perform grinding operations on the outer side of the copper sleeve body 6. Throughout the process, the slide groove 1 403, slide groove 2 404, and limiting groove 402 of the guide component 4 respectively guide and limit the support plate 501, mounting block 502, and rotating disk 204, ensuring stable and accurate adjustment. At the same time, the graphite particles 8 on the copper sleeve body 6 can achieve self-lubrication in subsequent use.
