Description

Technical Field

[0001] This application relates to the field of machining technology, specifically to a shaft polishing device. Background Technology

[0002] As a core component in a mechanical transmission system, the surface quality of the shaft core directly affects transmission efficiency and equipment lifespan. In the field of precision machinery, such as high-end equipment like aero engines and CNC machine tools, the shaft core must withstand high speeds, high torques, and complex alternating stresses for extended periods. If the shaft core surface has microscopic defects, substandard roughness, or shape errors, it can lead to abnormal vibrations and friction during operation, resulting in increased energy loss, accelerated wear of components, and even equipment malfunctions and downtime.

[0003] An existing patent (publication number: CN222741135U) discloses a polishing device for mandrel processing. It includes a base plate, a vertical plate connected to the upper end of the base plate, a polishing plate slidably mounted on one side wall of the vertical plate, a lifting component for driving the polishing plate to move vertically mounted on the vertical plate, and a through hole opened on one side wall of the vertical plate, with the through hole located below the polishing plate.

[0004] The above solution uses an electric push rod to drive the clamping plate to clamp and fix the shaft core. However, since the clamping plate directly contacts and clamps the shaft core, the part clamped by the clamping plate cannot be polished, which seriously affects the polishing quality and integrity of the overall surface of the shaft core, reduces the product qualification rate and production efficiency. At the same time, there is a lack of real-time quality monitoring methods during the entire polishing process, making it impossible to detect quality problems such as substandard surface roughness and uneven polishing in a timely manner. Only random inspection can be carried out after polishing is completed, which wastes a lot of time and manpower. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a shaft polishing device that enables full-process quality monitoring of the polishing process, solving the problem that traditional processes can only perform random inspections and improving quality control efficiency. At the same time, the internal support component fixes shaft bodies of different diameters through internal support, avoiding the obstruction of the polishing area by traditional external clamps, so that the shaft surface can obtain complete polishing treatment, significantly improving the surface quality and integrity of the product.

[0006] To achieve the above objectives, this application provides the following technical solution: a shaft polishing device, comprising a frame, a controller fixedly mounted on the upper side of the frame, the controller integrating a data processing module, an image acquisition device fixedly mounted on the inner side of the frame, an inner support assembly provided on the inner side of the frame, a first drive motor fixedly embedded on the outer side of the frame, a shaft body provided on the inner side of the frame, a lead screw rotatably connected to the inner side of the frame, a servo motor fixedly embedded on the outer side of the frame, and the output end of the servo motor fixedly connected to one end of the lead screw, a movable seat threadedly connected to the outer side of the lead screw, an extension plate fixedly connected to the outer side of the movable seat, and a laser rangefinder sensor fixedly mounted on the upper side of the extension plate.

[0007] Through the above solution, by setting up the integrated configuration of the controller and data processing module, the data from the image acquisition device and the laser rangefinder sensor can be analyzed in real time, realizing full-process quality monitoring of the polishing process. This solves the problem that traditional processes can only perform random inspections, improving the efficiency of quality control. At the same time, the internal support component fixes the shaft core body of different diameters through the internal support method, avoiding the obstruction of the polishing area by the traditional external clamping fixture, so that the shaft core surface can obtain complete polishing treatment, significantly improving the surface quality and integrity of the product.

[0008] Furthermore, a guide rod is fixedly connected to the inner side of the frame, and the inner side of the movable seat is slidably connected to the outer side of the guide rod.

[0009] With the above solution, the guide rod and the moving seat are slidably engaged, providing stable guidance for the movement of the moving seat under the drive of the lead screw. This ensures that the laser rangefinder and the subsequent polishing mechanism can move accurately along a fixed trajectory, avoiding deviations that could lead to detection and polishing errors, and improving the stability of equipment operation and the consistency of polishing quality.

[0010] Furthermore, a second guide groove is provided on the upper side of the movable seat, and an electric push rod is fixedly connected to the upper side of the movable seat. The output end of the electric push rod is fixedly connected to a mounting bracket, and the outer side of the mounting bracket is slidably connected to the inner side of the second guide groove.

[0011] The above solution allows for flexible adjustment of the relative position and contact pressure between the polishing belt and the shaft core body by setting an electric push rod to drive the mounting bracket to slide within the second guide groove. This not only adapts to the polishing needs of shaft core bodies of different specifications, but also allows for timely adjustment of the polishing intensity based on quality monitoring results during the polishing process, thus achieving refined polishing operations.

[0012] Furthermore, a power roller is rotatably connected to the inner side of the mounting frame, a driven roller is rotatably connected to the inner side of the mounting frame, a second drive motor is fixedly embedded on the outer side of the mounting frame, and the output end of the second drive motor is fixedly connected to one end of the power roller. A polishing belt is provided on the outer side of the driven roller, and the driven roller and the power roller are connected by a polishing belt.

[0013] Through the above scheme, the second drive motor drives the power roller, polishing belt and driven roller to operate synchronously, thereby forming a polishing motion. This can continuously polish the surface of the shaft core body in all directions without dead angles, effectively solving the problem of uneven polishing and ensuring the reliability of the polishing effect.

[0014] Furthermore, the inner support assembly includes a rotating disk rotatably connected to the inner side of the frame. The outer side of the rotating disk is fixedly connected to the output end of the first drive motor. The outer side of the rotating disk is provided with four circumferentially arrayed first guide grooves, and an arc-shaped support plate is slidably connected to the inner side of each first guide groove.

[0015] Through the above scheme, the arc-shaped support plate moves radially along the first guide groove, ensuring that the arc-shaped support plate achieves stable support from inside the shaft core body, so that the entire outer surface of the shaft core body can be fully exposed, creating conditions for achieving full-surface polishing, and greatly improving the polishing quality and integrity of the overall surface of the shaft core body.

[0016] Furthermore, an anti-slip pad is fixedly connected to the outer side of the arc-shaped support plate. The anti-slip pad is made of rubber and has anti-slip texture on its outer side.

[0017] The above solution, by setting anti-slip pads and anti-slip patterns made of rubber, significantly increases the friction with the inner wall of the shaft core body. When the shaft core body is internally supported and fixed, it can effectively prevent the shaft core body from sliding or moving during the polishing process, ensuring that the shaft core body maintains a stable posture during the polishing process, improving the polishing accuracy. At the same time, the rubber material can also avoid damaging the inner wall of the shaft core body.

[0018] Furthermore, a fixed sleeve is fixedly connected to the outer side of the rotating disk, a hydraulic rod is fixedly connected to the inner side of the fixed sleeve, and a sliding sleeve is fixedly connected to the output end of the hydraulic rod, with the inner side of the sliding sleeve slidably connected to the outer side of the fixed sleeve.

[0019] The above scheme, by precisely controlling the extension and retraction of the hydraulic rod, thereby adjusting the movement of the arc-shaped support plate, enables adaptive internal support fixing of shaft cores with different inner diameters, allowing the equipment to adapt to shaft cores of various specifications, thus enhancing the equipment's versatility and applicability.

[0020] Furthermore, the outer side of the sliding sleeve is fixedly connected to a first fixed plate in a circumferential array, the outer side of each of the four servo motors is hinged with two hinge rods, the inner side of each of the four arc-shaped support plates is fixedly connected to a second fixed plate, and the other end of each hinge rod is hinged to the outer side of the second fixed plate.

[0021] The above-mentioned transmission structure, consisting of a sliding sleeve, a first fixed plate, a hinge rod, and a second fixed plate, can convert the linear motion of the hydraulic rod into the radial synchronous movement of the arc-shaped support plate. This ensures that the internal support force of the four arc-shaped support plates on the shaft core body is evenly distributed, preventing deformation of the shaft core body due to uneven force distribution. It also ensures that the shaft core body is under stable force during polishing and improves the polishing quality.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This shaft polishing equipment, through the integrated setup of a controller and a data processing module, can perform real-time analysis of data from an image acquisition device and a laser rangefinder, realizing full-process quality monitoring of the polishing process. This solves the problem that traditional processes can only perform random sampling, improving the efficiency of quality control. At the same time, the internal support component fixes shaft bodies of different diameters through internal support, avoiding the obstruction of the polishing area by traditional external clamps, allowing the shaft surface to obtain complete polishing treatment, significantly improving the surface quality and integrity of the product, and solving the problems mentioned in the background technology.

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

[0032] Please see Figure 1 , Figure 2 and Figure 4 This embodiment of a shaft polishing device includes a frame 1, a controller 2 fixedly mounted on the upper side of the frame 1, and a data processing module integrated inside the controller 2. The integrated configuration of the controller 2 and the data processing module enables real-time analysis of data from the image acquisition device 3 and the laser rangefinder 11, realizing full-process quality monitoring of the polishing process, solving the problem that traditional processes can only perform random inspections, and improving the efficiency of quality control. The image acquisition device 3 is fixedly mounted on the inner side of the frame 1, and an inner support assembly 4 is provided on the inner side of the frame 1. The inner support assembly 4 fixes shaft bodies 5 of different diameters through an inner support method, avoiding the obstruction of the polishing area by traditional external clamps, so that the shaft surface can obtain complete polishing treatment, significantly improving the surface quality and integrity of the product. A first drive motor 19 is fixedly embedded on the outer side of the frame 1. The inner support assembly 4 includes a rotating disk 401 rotatably connected to the inner side of the frame 1, and the outer side of the rotating disk 401 is fixedly connected to the output end of the first drive motor 19.

[0033] Please see Figure 1 and Figure 4The outer side of the rotating disk 401 has four circumferentially arrayed first guide grooves 402. An arc-shaped support plate 403 is slidably connected to the inner side of each first guide groove 402. The arc-shaped support plate 403 moves radially along the first guide groove 402, ensuring stable support from inside the shaft core body 5. This allows the entire outer surface of the shaft core body 5 to be fully exposed, creating conditions for full-surface polishing and greatly improving the polishing quality and integrity of the overall surface of the shaft core body 5. The outer side of the arc-shaped support plate 403 is fixed... The fixed connection is equipped with an anti-slip pad 404, which is made of rubber. The anti-slip pad 404 has anti-slip texture on its outer side. By setting the rubber anti-slip pad 404 and the anti-slip texture, the friction between the anti-slip pad 404 and the inner wall of the shaft core body 5 is significantly increased. When the shaft core body 5 is internally supported and fixed, it can effectively prevent the shaft core body 5 from sliding or moving during the polishing process, ensuring that the shaft core body 5 maintains a stable posture during the polishing process, improving the polishing accuracy. At the same time, the rubber material can also avoid damage to the inner wall of the shaft core body 5.

[0034] Please see Figure 4 and Figure 5 A fixed sleeve 405 is fixedly connected to the outer side of the rotating disk 401, and a hydraulic rod 406 is fixedly connected to the inner side of the fixed sleeve 405. A sliding sleeve 407 is fixedly connected to the output end of the hydraulic rod 406, and the inner side of the sliding sleeve 407 is slidably connected to the outer side of the fixed sleeve 405. By precisely controlling the extension and retraction of the hydraulic rod 406, the movement of the arc-shaped support plate 403 can be adjusted, enabling adaptive internal support fixing of shaft core bodies 5 with different inner diameters. This allows the equipment to adapt to shaft core bodies 5 of various specifications, enhancing the versatility and applicability of the equipment. Four circumferentially arrayed first fixed plates 408 are fixedly connected to the outer side of the sliding sleeve 407, and four servo... Two hinge rods 409 are hinged to the outer side of the motor 8, and a second fixing plate 410 is fixedly connected to the inner side of each of the four arc-shaped support plates 403. The other end of each hinge rod 409 is hinged to the outer side of the second fixing plate 410. The transmission structure consisting of the sliding sleeve 407, the first fixing plate 408, the hinge rods 409, and the second fixing plate 410 can convert the linear motion of the hydraulic rod 406 into the radial synchronous movement of the arc-shaped support plates 403. This ensures that the internal support force of the four arc-shaped support plates 403 on the shaft core body 5 is evenly distributed, avoids deformation of the shaft core body 5 due to uneven force, ensures the stability of the shaft core body 5 during polishing, and improves the polishing quality.

[0035] Please see Figure 1 , Figure 2 and Figure 3The frame 1 has a shaft core body 5 on its inner side and a lead screw 6 rotatably connected to the inner side of the frame 1. A servo motor 8 is fixedly embedded on the outer side of the frame 1, and the output end of the servo motor 8 is fixedly connected to one end of the lead screw 6. A movable seat 9 is threadedly connected to the outer side of the lead screw 6, and an extension plate 10 is fixedly connected to the outer side of the movable seat 9. A laser rangefinder 11 is fixedly installed on the upper side of the extension plate 10. The laser rangefinder 11 is used to measure the surface roughness of the shaft core. By emitting a laser beam and receiving the reflected light, the undulation of the shaft core surface is calculated, thereby obtaining surface roughness data. A guide rod 7 is fixedly connected to the inner side of the frame 1, and the inner side of the movable seat 9 is slidably connected to the outer side of the guide rod 7. The guide rod 7 and the movable seat 9 are slidably engaged to provide stable guidance for the movement of the movable seat 9 under the drive of the lead screw 6. This ensures that the laser rangefinder 11 and the subsequent polishing mechanism can move accurately along a fixed trajectory, avoiding deviation that could lead to detection and polishing errors, and improving the stability of equipment operation and the consistency of polishing quality.

[0036] Please see Figure 2 and Figure 3 The upper side of the movable seat 9 is provided with a second guide groove 12. An electric push rod 13 is fixedly connected to the upper side of the movable seat 9. The output end of the electric push rod 13 is fixedly connected to a mounting bracket 14, and the outer side of the mounting bracket 14 is slidably connected to the inner side of the second guide groove 12. By setting the electric push rod 13 to drive the mounting bracket 14 to slide in the second guide groove 12, the relative position and contact pressure between the polishing belt 17 and the shaft core body 5 can be flexibly adjusted. This not only adapts to the polishing needs of shaft core bodies 5 of different specifications, but also allows for timely adjustment of the polishing intensity based on quality monitoring results during the polishing process, achieving fine polishing operations. The inner side of the mounting bracket 14 is rotated... A power roller 15 is connected to the inner side of the mounting frame 14, and a driven roller 16 is rotatably connected to it. A second drive motor 18 is fixedly embedded on the outer side of the mounting frame 14, and the output end of the second drive motor 18 is fixedly connected to one end of the power roller 15. A polishing belt 17 is provided on the outer side of the driven roller 16. The driven roller 16 and the power roller 15 are connected by a transmission through the polishing belt 17. The second drive motor 18 drives the power roller 15, the polishing belt 17 and the driven roller 16 to rotate synchronously, thereby forming a polishing motion. This can continuously polish the surface of the shaft core body 5 in all directions without dead angles, effectively solving the problem of uneven polishing and ensuring the reliability of the polishing effect.

[0037] The shaft polishing equipment in this embodiment, through the integrated configuration of controller 2 and data processing module, can perform real-time analysis of data from image acquisition device 3 and laser rangefinder 11, realizing full-process quality monitoring of the polishing process. This solves the problem that traditional processes can only perform random inspections, improving the efficiency of quality control. At the same time, the internal support component 4 fixes shaft bodies 5 of different diameters through internal support, avoiding the obstruction of the polishing area by traditional external clamps, allowing the shaft surface to obtain complete polishing treatment, significantly improving the surface quality and integrity of the product, and solving the problems mentioned in the background art.

[0038] The working principle of the above embodiment is as follows: The shaft core body 5 is placed inside the frame 1. At this time, the hydraulic rod 406 extends and pushes the sliding sleeve 407 to move. Through the transmission components such as the hinge rod 409, the four arc-shaped support plates 403 expand radially along the first guide groove 402, tightly supporting the shaft core body 5 from the inside. The rubber anti-slip pad 404 is attached to the inner wall of the shaft core body 5 to prevent slippage. Then, the first drive motor 19 starts, driving the rotating disk 401 and the shaft core body 5 to rotate. Then, the servo motor 8 drives the lead screw 6 to rotate. Under the guidance of the guide rod 7, the moving seat 9 drives the extension plate 10 and the laser rangefinder sensor 11 to move back and forth. The electric push rod 13 adjusts the position of the mounting bracket 14, changing the contact pressure between the polishing belt 17 and the shaft core body 5. At the same time, it controls the second drive motor 18 to adjust the speed of the power roller 15, changing the polishing force and speed of the polishing belt 17. Then, the second drive motor 18 drives the power roller 15, the polishing belt 17 and the driven roller 16 to rotate synchronously to polish the outer surface of the shaft core body 5. During the polishing process, the laser range sensor 11 and the image acquisition device 3 continuously monitor the process, and the controller 2 adjusts the polishing parameters in real time until the polishing quality of the shaft core body 5 meets the standard. Finally, the hydraulic rod 406 retracts, and the arc-shaped support plate 403 retracts to release the shaft core body 5, completing the polishing operation.
