Description

Technical Field

[0001] This utility model relates to the field of aluminum rod production and processing technology, and in particular to a polishing device for aluminum rod production and processing. Background Technology

[0002] Aluminum rod production is a crucial process in which molten aluminum is formed into rod-shaped metal materials of specific diameters and lengths through processes such as casting, extrusion, or drawing. It is widely used in construction, transportation, electronics, and machinery manufacturing. As an important component of basic industrial materials, its surface quality directly affects the yield of subsequent processing and the appearance and performance of the final product. Surface polishing, as a core post-processing step in aluminum rod production to improve surface smoothness and eliminate burrs and minor defects, has a decisive impact on the overall product quality, production costs, and delivery cycle due to its processing methods and efficiency. Especially in the continuous operation of automated production lines, while existing polishing equipment has a certain clamping and adjustment capability when handling aluminum rods of different diameters, enabling uniform polishing and dust collection of individual rods, it still reveals a series of significant limitations and technical problems in practical applications.

[0003] Specifically, existing polishing devices, such as the surface polishing device for aluminum rod production and processing disclosed in utility model patent CN215148015U, can achieve automatic clamping and reciprocating polishing of aluminum rods of different diameters by setting a moving mechanism with a reciprocating screw and slide on the processing table, combined with a polishing head driven by an electric push rod, and effectively ensure the uniformity of polishing. At the same time, it integrates a dust removal and purification system to deal with the dust and debris generated during the polishing process, which significantly improves the working environment and reduces environmental pollution and operational risks.

[0004] However, this device is designed to polish only single aluminum rods, processing only one rod at a time. When faced with large-volume, multi-specification production tasks, frequent cycles of loading, clamping, polishing, and unloading are required, resulting in high equipment idle rates and significantly limiting the overall efficiency of the production line. This fails to meet the urgent demands of modern aluminum processing for high capacity and rapid turnover, severely restricting the improvement of production speed. Therefore, addressing the problem that existing technologies cannot effectively polish single aluminum rods while simultaneously processing multiple rods in parallel, we urgently need an innovative polishing device for aluminum rod production to solve these challenges. Utility Model Content

[0005] The purpose of this utility model is to provide a polishing device for aluminum rod production and processing, which solves the problem that the existing technology can only polish a single aluminum rod at a time. When faced with large-volume and multi-specification production tasks, it is necessary to frequently perform cyclical operations of loading, clamping, polishing, and unloading, resulting in high equipment idle rate, which greatly limits the overall efficiency of the production line and cannot meet the urgent needs of modern aluminum processing for high capacity and fast turnover.

[0006] To achieve the above objectives, this utility model provides a polishing device for aluminum rod production and processing, including a frame, a top plate fixedly connected to the top of the frame, and a bearing plate slidably connected to the inner side of the frame;

[0007] The top of the support plate is slidably connected to several annular plates, and the top of all the annular plates is fixedly connected to polishing sleeves. Adjacent polishing sleeves are meshed together. A drive motor is fixedly connected to the bottom side of the support plate by bolts, and a rotating rod is rotatably connected to the top side of the support plate. The top end of the rotating rod is meshed with one of the polishing sleeves, and the bottom end of the rotating rod passes through the support plate and is connected to the output shaft of the drive motor. A pressure plate is provided at the bottom of the top plate, and a first cylinder is fixedly connected to the top side of the top plate by bolts. The output shaft of the first cylinder passes through the top of the top plate and is fixedly connected to the top of the pressure plate.

[0008] The support plate has sliders fixedly connected to both sides, and both sliders are slidably connected to the side wall of the frame through a groove.

[0009] The frame has base plates fixedly connected to both sides of its lower part, and the bottom of each base plate is fixedly connected to a second cylinder by bolts. The output shafts of the two second cylinders pass through the two base plates respectively, and the output shafts of the second cylinders are fixedly connected to the bottom of the slider.

[0010] All the annular plates have protrusions fixedly connected to their bottoms, and all the protrusions are slidably connected to the top of the support plate through annular grooves.

[0011] All polishing sleeves are fitted with gear sleeves on their outer sides, and all adjacent gear sleeves are meshed together. The top of the rotating rod is fixedly connected to a gear disk, which is meshed with one of the gear sleeves.

[0012] The inner bottom of the frame is fixedly connected to several bearing cylinders, and the bearing cylinders are distributed in a one-to-one correspondence with all the polishing sleeves. The bearing plate has a bottom groove on the side close to all the polishing sleeves.

[0013] This utility model discloses a polishing device for aluminum rod production and processing. It features multiple parallel annular plates on a support plate, with multiple interlocking polishing sleeves fixedly installed on these plates. A drive motor drives one polishing sleeve via a rotating rod, and gear meshing drives all polishing sleeves to rotate synchronously. This design enables simultaneous polishing of multiple aluminum rods inserted into all polishing sleeves, fundamentally changing the existing single-rod sequential processing mode. It significantly increases the processing quantity per unit time and effectively solves the problems of high equipment idle rate, long processing cycles, and low overall efficiency caused by single-rod processing. This greatly improves the overall processing speed of aluminum rods and meets the needs of large-volume production. To meet the demands of high-capacity production, an axial limiting mechanism consisting of a top plate, a first cylinder, and a pressure plate is used. This mechanism applies uniform downward pressure to the tops of all aluminum rods before polishing begins, ensuring that multiple aluminum rods are reliably axially fixed within the high-speed rotating polishing sleeve. This prevents the aluminum rods from shifting upwards or jumping due to vibration or uneven friction, ensuring the stability and safety of the simultaneous polishing process. It avoids the problems of complex and costly single-rod clamping mechanisms. The sliding connection design of the bearing plate within the frame allows it to drive the entire polishing sleeve to move, realizing the feeding motion of the polishing sleeve along the length of the aluminum rod. This ensures uniform polishing quality across the entire surface of the aluminum rod, avoiding localized over-polishing or under-polishing. Attached Figure Description

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Please see Figure 1-5 .

[0023] A polishing device for aluminum rod production and processing includes a frame 1, a top plate 2 fixedly connected to the top of the frame 1, and a bearing plate 5 slidably connected to the inner side of the frame 1.

[0024] The top of the support plate 5 is slidably connected to several annular plates 6, and the top of all the annular plates 6 is fixedly connected to polishing sleeves 9. The two adjacent polishing sleeves 9 are meshed together. The bottom side of the support plate 5 is fixedly connected to a drive motor 18 by bolts, and the top side of the support plate 5 is rotatably connected to a rotating rod 17. The top end of the rotating rod 17 is meshed with one of the polishing sleeves 9. The bottom end of the rotating rod 17 passes through the support plate 5 and is connected to the output shaft of the drive motor 18. The bottom of the top plate 2 is provided with a pressure plate 3, and the top side of the top plate 2 is fixedly connected to a first cylinder 4 by bolts. The output shaft of the first cylinder 4 passes through the top of the top plate 2 and is fixedly connected to the top of the pressure plate 3.

[0025] During the polishing process of aluminum rod production, multiple aluminum rods to be polished are first inserted parallel to each other from the opening at the top of the frame 1 downwards. They pass sequentially through the central holes of multiple annular plates 6 fixed to the top of the support plate 5 and into the polishing sleeves 9 located above the annular plates 6. All polishing sleeves 9 are evenly arranged along the length of the support plate 5. After all aluminum rods are correctly inserted, the first cylinder 4 fixed to the top of the top plate 2 is activated. The output shaft of the first cylinder 4 extends downwards, pushing the pressure plate 3 fixed to it downwards in the vertical direction. The lower surface of the pressure plate 3 contacts the tops of all aluminum rods and applies downward pressure, thereby axially squeezing and limiting all aluminum rods to prevent axial movement or upward shift during polishing, ensuring the stability of the polishing process. After limiting, the drive motor 18 fixed to the bottom of the support plate 5 is activated. The output shaft of the drive motor 18 drives the rotating rod 17 connected to it to rotate. The top of the rotating rod 17 contacts one of the... The external teeth of the polishing sleeves 9 mesh, and since all adjacent polishing sleeves 9 are also connected by external teeth meshing, the rotational power of the rotating rod 17 is transmitted to all polishing sleeves 9 in sequence through gear meshing, so that all polishing sleeves 9 rotate synchronously. The inner wall of the high-speed rotating polishing sleeve 9 rubs and polishes the outer surface of the aluminum rod passing through it, realizing synchronous surface treatment of multiple aluminum rods. During the polishing process, the bearing plate 5 itself can slide vertically inside the frame 1. By controlling the bearing plate 5, all polishing sleeves 9 on it are moved up or down as a whole, so that the polishing sleeves 9 can reciprocate or move unidirectionally along the entire length of the aluminum rod to polish, ensuring that the surface of the aluminum rod is uniformly treated throughout its entire length. After polishing is completed, the first cylinder 4 drives the pressure plate 3 to reset and move upward, releasing the axial pressure on the aluminum rod. Then, all polished aluminum rods can be simultaneously extracted from the polishing sleeves 9, completing one processing cycle and preparing for the feeding of the next batch of aluminum rods.

[0026] Furthermore, sliders 11 are fixedly connected to both sides of the bearing plate 5, and both sliders 11 are slidably connected to the side wall of the frame 1 through the slide groove 12. When the output shaft of the second cylinder 14 extends or retracts, it drives the sliders 11 fixed thereto to slide up and down in the slide groove 12 on the side wall of the frame 1, thereby guiding and supporting the bearing plate 5 to move smoothly in the vertical direction. This achieves the effect of ensuring that the bearing plate 5 and all polishing sleeves 9 on it have accurate and stable running trajectory during the lifting process, avoiding shaking or jamming, and improving the polishing feed accuracy and overall structural stability.

[0027] Furthermore, base plates 13 are fixedly connected to both sides of the lower part of the frame 1, and the bottom of each base plate 13 is fixedly connected to a second cylinder 14 by bolts. The output shafts of the two second cylinders 14 pass through the two base plates 13 respectively. The output shafts of the second cylinders 14 are fixedly connected to the bottom of the slider 11. When the second cylinders 14 fixed on the base plates 13 are activated, their output shafts extend upwards and directly push the push rod connected to the bottom of the slider 11, thereby driving the bearing plate 5 to move upwards as a whole, realizing the feeding and polishing of the aluminum rod by the polishing sleeve 9, or controlling the output shaft to retract and lower the bearing plate 5 to reset. This achieves the effect of providing stable and controllable lifting power for the bearing plate 5, realizing automated feeding in the polishing process, and improving polishing efficiency and ease of operation.

[0028] Furthermore, all the bottom of the annular plates 6 are fixedly connected with protrusions 7, and all the protrusions 7 are slidably connected to the top of the support plate 5 through the annular grooves 8. When the polishing sleeve 9 rotates at high speed due to gear meshing, the annular plate 6 below it rotates accordingly. The protrusions 7 at the bottom of the annular plate 6 slide in the annular grooves 8 at the top of the support plate 5, allowing the annular plate 6 and the polishing sleeve 9 to rotate freely relative to the support plate 5, while keeping their axial position fixed. This achieves the effect of ensuring that the polishing sleeve 9 can independently and smoothly perform high-speed rotation polishing while the support plate 5 moves up and down, avoiding obstruction of power transmission or structural interference.

[0029] Furthermore, gear sleeves 10 are fitted onto the outer side of all polishing sleeves 9, and adjacent gear sleeves 10 are meshed together. A gear disk 16 is fixedly connected to the top of the rotating rod 17, and the gear disk 16 is meshed with one of the gear sleeves 10. The drive motor 18 drives the gear disk 16 to rotate through the rotating rod 17. The gear disk 16 meshes with one of the gear sleeves 10, transmitting power to that gear sleeve 10. Through the mutual meshing between adjacent gear sleeves 10, all gear sleeves 10 are driven to rotate synchronously, thereby driving all polishing sleeves 9 to rotate synchronously. This achieves the effects of optimizing the power transmission path, enhancing the stability and reliability of gear meshing, ensuring the synchronous and efficient operation of multiple polishing sleeves 9, and improving transmission efficiency and system durability.

[0030] Furthermore, several bearing cylinders 15 are fixedly connected to the bottom inner side of the frame 1, and the bearing cylinders 15 are distributed in a one-to-one correspondence with all the polishing sleeves 9. The bearing plate 5 has a bottom groove 19 on one side close to all the polishing sleeves 9. When the bearing plate 5 rises to the highest position for polishing, the bearing cylinder 15 can support the bottom end of the aluminum rod from below, providing additional support and preventing the slender aluminum rod from bending or vibrating due to excessive cantilever length. At the same time, the bottom groove 19 provides space for the bearing plate 5 to avoid the bearing cylinder 15 when it rises, thereby enhancing the overall support rigidity of the polished aluminum rod, reducing vibration and deformation during processing, improving the polishing surface quality and processing stability, and ensuring that the bearing plate 5 rises and falls smoothly without interference.

[0031] In summary:

[0032] During the polishing process of aluminum rod production, multiple aluminum rods to be polished are first inserted parallel to each other downwards from the opening at the top of the frame 1. These rods pass sequentially through the central holes of multiple annular plates 6 fixed to the top of the support plate 5 and into the polishing sleeves 9 located above the annular plates 6. All polishing sleeves 9 are evenly arranged along the length of the support plate 5. Once all aluminum rods are correctly inserted, the first cylinder 4 fixed to the top of the top plate 2 is activated. The output shaft of the first cylinder 4 extends downwards, pushing the pressure plate 3 fixedly connected to it downwards in the vertical direction. The lower surface of the pressure plate 3 contacts the tops of all the aluminum rods and applies downward pressure, thereby axially compressing all the aluminum rods. A limit switch is installed to prevent axial movement or upward displacement during polishing, ensuring the stability of the polishing process. After the limit switch is completed, the drive motor 18 fixed to the bottom of the support plate 5 is started. The output shaft of the drive motor 18 drives the rotating rod 17 connected to it to rotate. A gear disk 16 is fixedly connected to the top of the rotating rod 17. The gear disk 16 meshes with the gear sleeve 10 that is sleeved on the outside of one of the polishing sleeves 9. Since all adjacent gear sleeves 10 are meshed with each other, the rotational power of the rotating rod 17 is transmitted to all the polishing sleeves 9 in sequence through the meshing of the gear disk 16 and the gear sleeve 10, so that all the polishing sleeves 9 rotate synchronously at high speed, polishing the polishing sleeves through their interiors. The outer surface of the aluminum rods is rubbed and polished to achieve simultaneous surface treatment of multiple aluminum rods. During the polishing process, the second cylinder 14 fixed to the bottom of the base plate 13 is activated. The output axis of the second cylinder 14 extends upward and pushes the slider 11 fixedly connected to it. The slider 11 slides in the groove 12 on the side wall of the frame 1, thereby driving the entire support plate 5 to rise smoothly in the vertical direction. The rise of the support plate 5 causes all the polishing sleeves 9 on it to move along the length of the aluminum rod for polishing. When the support plate 5 rises, the bottom groove 19 opened near each polishing sleeve 9 provides clearance space for the support cylinder 15 below. At the same time, the support cylinder 15 lifts the bottom end of the aluminum rod from below. The support plate 5 provides support to prevent the slender aluminum rod from bending or vibrating during polishing. After the bearing plate 5 rises to the predetermined position and completes the polishing stroke, the second cylinder 14 controls the output shaft to retract, driving the bearing plate 5 to descend and reset. After polishing is completed, the first cylinder 4 drives the pressure plate 3 to reset and move upward, relieving the axial pressure on the aluminum rod. Then, all the polished aluminum rods can be simultaneously pulled out from the polishing sleeve 9 to complete one processing cycle and prepare for the feeding of the next batch of aluminum rods. Throughout the process, the protrusion 7 at the bottom of the annular plate 6 slides in the annular groove 8 at the top of the bearing plate 5, allowing the annular plate 6 and the polishing sleeve 9 to rotate freely relative to the bearing plate 5 at high speed, thus avoiding structural interference.By setting multiple parallel annular plates 6 and polishing sleeves 9, combined with a power transmission system consisting of a drive motor 18, a rotating rod 17, a gear disk 16, and meshing gear sleeves 10, simultaneous polishing of multiple aluminum rods is achieved. This effectively solves the problem of low single-rod processing efficiency in existing technologies, significantly improving the overall processing speed and production efficiency. The first cylinder 4 drives the pressure plate 3 to uniformly axially compress and limit the tops of all aluminum rods, ensuring the stability and safety of multiple aluminum rods during synchronous polishing and preventing axial movement. The second cylinder 14 serves as the power source, pushing the support plate 5 connected to the slider 11 to smoothly rise and fall along the slide groove 12 on the side wall of the frame 1, realizing the automatic feeding motion of the polishing sleeve 9 onto the aluminum rods. This improves the automation level and ease of operation of the polishing process. The cooperation between the slider 11 and the slide groove 12 ensures the accuracy and stability of the lifting trajectory of the support plate 5, avoiding shaking or jamming and improving the polishing feed accuracy. The protrusion 7 at the bottom of the annular plate 6 is located at the top of the support plate 5. The sliding structure within the annular groove 8 allows the polishing sleeve 9 to rotate freely relative to the support plate 5 during high-speed rotation while maintaining axial fixation. This effectively avoids motion interference between the rotating and lifting components, ensuring smooth power transmission and stable system operation. The meshing transmission of the gear sleeve 10 and gear disc 16 optimizes the power transmission path, enhances the stability and reliability of multi-gear meshing, ensures that all polishing sleeves 9 operate synchronously and efficiently, and improves transmission efficiency and system durability. Multiple support cylinders 15 at the bottom correspond one-to-one with the polishing sleeves 9, supporting the bottom of the aluminum rod from below when the support plate 5 rises for polishing. This effectively enhances the overall support rigidity of the slender aluminum rod, reduces vibration and bending deformation during processing, and improves the polished surface quality and processing stability. The bottom groove 19 on the support plate 5 provides necessary clearance space for the support cylinders 15, ensuring smooth and interference-free lifting of the support plate 5. The base plate 13 provides a stable mounting foundation for the second cylinder 14.
