Description

Technical Field

[0001] This utility model relates to the field of polishing equipment technology, and in particular to an automated aluminum cylinder surface polishing equipment. Background Technology

[0002] In modern industrial manufacturing, aluminum cylinders are widely used in aerospace, automobile manufacturing, electronic equipment and many other industries due to their excellent metallic properties. To meet the stringent requirements of various industries for the surface quality of aluminum cylinders, surface polishing has become a key step. With the continuous improvement of the automation level of manufacturing, traditional manual polishing can no longer meet the needs of large-scale and high-precision production. There is an urgent need for an automated aluminum cylinder surface polishing equipment to improve production efficiency, ensure the stability of polishing quality, reduce labor costs and labor intensity, and ensure the efficient and precise operation of the production process.

[0003] In existing aluminum cylinder surface polishing technologies, some employ simple clamping devices to secure the aluminum cylinder, using mechanical clamps to hold it tightly from the outside. The principle is to utilize friction and mechanical pressure to keep the aluminum cylinder stable during polishing. Regarding dust handling generated during polishing, some methods involve setting up simple dust extraction hoods around the work area, using the suction power of ordinary fans to draw aluminum powder into a dust collection bag. Others use inclined surfaces on the worktable, allowing the aluminum powder to slide down into a collection tank due to its own gravity.

[0004] Existing technologies struggle to efficiently handle the fixing of aluminum cylinders with varying inner diameters. Due to the wide range of applications and diverse inner diameter specifications of aluminum cylinders, traditional external clamping methods cannot flexibly adapt to changes in the inner diameter of the aluminum cylinder, easily leading to unstable fixing. This results in displacement of the aluminum cylinder during polishing, affecting the polishing quality. Furthermore, frequent replacement of the fixing device is time-consuming and labor-intensive, severely reducing the efficiency of pre-polishing preparation work and significantly restricting the overall efficiency and quality of aluminum cylinder surface polishing operations. Therefore, an automated aluminum cylinder surface polishing device is proposed to solve the above problems. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 and Figure 2 The present invention provides an embodiment of an automated aluminum cylinder surface polishing device, including a robotic arm 2. The robotic arm 2 is used to achieve precise position movement and angle adjustment, driving the base 7 and the aluminum cylinder 4 fixed thereon to a designated position to prepare for subsequent polishing operations. The output end of the robotic arm 2 is fixedly connected to the base 7 for supporting and connecting the fixed components, transmitting the power of the robotic arm 2 to the fixed components, and ensuring that the fixed components can move accurately with the movement of the robotic arm 2. The fixed components are provided at the bottom of the base 7, and the polishing components are provided on the side wall of the robotic arm 2.

[0035] The fixing assembly includes a connecting plate 8, which is made of stainless steel and has good corrosion resistance and strength. The connecting plate 8 connects the base 7 and the electric actuator 9. The top of the connecting plate 8 is fixedly connected to the bottom of the base 7 by bolts. The electric actuator 9 is fixedly connected to the bottom of the connecting plate 8. The electric actuator 9 generates thrust to move the push rod 10. Its function is to control the displacement of the push rod 10 according to control commands, thereby controlling the movable block 11 and related components. The output end of the electric actuator 9 is fixedly connected to the push rod 10 via a coupling. The push rod 10 is made of carbon steel and transmits the thrust of the electric actuator 9 to drive the movable block 11 to move. One end of the push rod 10 is fixedly connected to the movable block 11. The function of block 11 is to drive the connecting seat 12 and related components on its outer wall to move under the push of push rod 10, thereby realizing the expansion and contraction of movable plate 14 and fixing aluminum tube 4. Multiple connecting seats 12 are fixedly connected to the outer walls of movable block 11 and connecting plate 8 by welding. The connecting seats 12 are made of metal and their function is to connect the connecting arms 13, so that the connecting arms 13 can rotate inside them, thereby realizing the adjustment of the position of movable plate 14. The connecting seats 12 are distributed in a circumferential shape on the outer walls of movable block 11 and connecting plate 8. The connecting arms 13 are rotatably connected inside each connecting seat 12. The function of the connecting arms 13 is to convert the vertical displacement of movable block 11 into the horizontal position of movable plate 14. The movable plate 14 can be extended and retracted to accommodate the fixing requirements of aluminum tubes 4 with different inner diameters. Each connecting arm 13 has a rotatable connecting seat 12 at its other end. The connecting seat 12 has a movable plate 14 on its side wall. The movable plate 14 is made of metal and has anti-slip textures on its outer wall. Its function is to unfold and press against the inner wall of the aluminum tube 4 under the action of the connecting arm 13, thus fixing the aluminum tube 4. The side walls of the connecting seat 12 are fixedly connected to the side walls of the movable plate 14. The polishing assembly includes a polishing machine 5 for grinding and polishing operations. A base plate 1 is provided at the bottom of the polishing machine 5 to support the polishing machine 5 and the robotic arm 2. The bottoms of both the polishing machine 5 and the robotic arm 2 are fixedly connected to the top of the base plate 1. A support 3 is provided on the side. The function of the support 3 is to place and support the aluminum tube 4 to be polished, so that the robotic arm 2 can grasp and move it. The bottom of the support 3 is fixedly connected to the top of the base plate 1. Multiple aluminum tubes 4 are slidably connected to the top of the support 3. The aluminum tubes 4 are distributed in an array. A guide groove 6 is provided on the side of the polishing machine 5. It is used to guide aluminum powder into the dust collection tray 15 in conjunction with the air duct 17. The bottom of the guide groove 6 is fixedly connected to the top of the base plate 1. The air duct 17 is fixedly connected to the side of the guide groove 6 by welding. The air duct 17 is made of galvanized steel plate. Its function is to suck away the dust and other impurities generated during the polishing process by air force, keep the working environment clean, and prevent dust from affecting the polishing quality.

[0036] Specifically, when using this automated aluminum cylinder surface polishing equipment, the robotic arm 2 first receives a control command, and its internal motor starts. This motor, through a transmission device, drives the joints of the robotic arm 2 to move, aligning the connecting plate 8 with one end of the aluminum cylinder 4 located above the support 3. The robotic arm 2, through programmed control, adjusts its position and angle to ensure that the connecting plate 8 is accurately aligned with the opening of the aluminum cylinder 4. Subsequently, the robotic arm 2 continues to move, inserting the connecting plate 8 into the interior of the aluminum cylinder 4. At this time, the electric actuator 9 at the bottom of the connecting plate 8 receives a control signal, and the motor inside the electric actuator 9... Upon startup, the rotation of the motor is converted into linear motion of the push rod 10 via a transmission device, pushing the push rod 10 downward. This downward displacement of the push rod 10 causes the movable block 11 to also move downward. The displacement of the movable block 11 further causes multiple connecting seats 12 on its outer wall to move synchronously. As the connecting seats 12 on the outer wall of the movable block 11 move downward, the connecting arm 13 rotates. One end of the connecting arm 13 is connected to the connecting seat 12 on the outer wall of the movable block 11 via a rotating structure, and the other end is connected to the connecting seat 12 on the side wall of the movable plate 14 via a rotating structure. When the outer wall of the movable block 11... When the connecting seat 12 moves downward, the connecting arm 13 makes a circular motion around its connection point with the connecting seat 12 on the outer wall of the movable block 11. The rotation of the connecting arm 13, through its connection with the connecting seat 12 on the side wall of the movable plate 14, pushes the movable plate 14 to move towards the inner wall of the aluminum tube 4. With the cooperation of multiple connecting seats 12 and connecting arms 13 on the outer wall of the electric pusher 9, multiple movable plates 14 unfold and move linearly towards the inner wall of the aluminum tube 4 in a direction perpendicular to the inner wall of the aluminum tube 4, finally abutting against the inner wall of the aluminum tube 4. At this time, the movable plate 14 is in close contact with the inner wall of the aluminum tube 4. The contact generates friction, allowing the robotic arm 2 to move the aluminum tube 4. Subsequently, the robotic arm 2 receives another control command and moves the aluminum tube 4 to one side of the polishing machine 5, so that the surface of the aluminum tube 4 contacts the polishing belt of the polishing machine 5. Then the polishing machine 5 starts to grind and polish the aluminum tube 4, thereby achieving the effect of quickly fixing aluminum tubes 4 with different inner diameters. After the polishing operation is completed, the robotic arm 2 moves again to transport the polished aluminum tube 4 to the designated position, and then repeats the above operation to fix and polish the next aluminum tube 4.

[0037] Reference Figures 3-5A negative pressure fan 18 is installed inside the air duct 17. During operation, the motor drives the fan blades to rotate at high speed, creating a negative pressure environment inside the air duct 17. This draws aluminum powder from the air into the air duct 17 and guides it into the guide groove 6. The negative pressure fan 18 is fixedly connected inside the air duct 17. A filter plate 16, made of metal mesh, is installed on the side of the negative pressure fan 18. The filter plate 16 prevents impurities such as aluminum powder from entering deeper into the air duct 17, thus preventing damage to the negative pressure fan 18 and other equipment. Aluminum powder is collected on the side of filter plate 16 near guide groove 6 for easy cleaning. The side wall of filter plate 16 is fixedly connected to the inner wall of guide groove 6. Dust collection tray 15 is slidably connected inside guide groove 6. The function of dust collection tray 15 is to collect aluminum powder blocked by filter plate 16 for easy cleaning by staff. Handles are fixed to its side wall. Fixing box 20 is provided on the side wall of dust collection tray 15. Fixing box 20 works with locking block 19, limiting block 22 and limiting spring 21 to fix and remove dust collection tray 15 in guide groove 6. The fixed box 20 is located inside the guide groove 6. A locking block 19 is slidably connected inside the fixed box 20. The function of the locking block 19 is to cooperate with the limiting block 22 inside the fixed box 20 when the dust collection drawer 15 is installed in the guide groove 6, preventing the dust collection drawer 15 from accidentally sliding out of the guide groove 6. The side wall of the locking block 19 is fixedly connected to the side wall of the dust collection drawer 15. The fixed box 20 is provided with symmetrical left and right limiting blocks 22. The function of the limiting blocks 22 is to engage with the locking block 19 under the action of the limiting spring 21 when the dust collection drawer 15 is installed in place. The dust collection drawer 15 is locked in the slot on the side wall. The outer wall of the limiting block 22 is slidably connected to the inner wall of the fixing box 20. The side of the fixing box 20 is provided with limiting springs 21. The function of the limiting springs 21 is to push the limiting block 22 towards the locking block 19 when the dust collection drawer 15 is installed, so that the limiting block 22 is locked into the slot on the side wall of the locking block 19, thereby fixing the dust collection drawer 15. One end of the limiting spring 21 is fixedly connected to the inside of the fixing box 20, and the other end of the limiting spring 21 is fixedly connected to the side wall of the limiting block 22.

[0038] Specifically, during the grinding and polishing process, the polishing machine 5 grinds the aluminum cylinder tube 4, generating a large amount of aluminum powder. At this time, the negative pressure fan 18 located inside the air duct 17 at the bottom of the polishing machine 5 receives a start signal from the equipment control system. The motor inside the negative pressure fan 18 is powered on and starts, driving the fan blades to rotate. The high-speed rotation of the fan blades causes the air inside the air duct 17 to flow rapidly, creating a negative pressure environment. Under the action of negative pressure, the aluminum powder moves towards the filter plate 16 under the influence of the airflow. When the aluminum powder comes into contact with the filter plate 16, it is blocked outside the filter plate 16 due to the metal mesh structure of the filter plate 16. As the grinding and polishing work continues, more and more aluminum powder is blocked on the side of the filter plate 16 near the guide groove 6, gradually accumulating outside the filter plate 16. When the work is completed, the aluminum powder is concentrated inside the dust collection drawer 15. At this time, the operator manually pulls the side wall of the dust collection drawer 15 outward. Under the pulling force applied by the worker, the dust collection drawer 15 slides outward along the sliding track inside the guide groove 6. At this time, the locking block 19 on one side of the dust collection drawer 15 also moves outward. The side wall of the locking block 19 contacts the limiting block 22. When the locking block 19 moves outward, it applies a squeezing force to the limiting block 22 towards the inside of the fixing box 20. Under the action of this squeezing force, the limiting block 22 moves linearly towards the inside of the fixing box 20, thereby compressing the limiting spring 21. After the locking block 19 disengages from the limiting block 22, the worker can continue to pull the dust collection drawer 15 to completely remove it from the guide groove 6. The worker places the dust collection drawer 15 in the designated cleaning position to clean the aluminum powder concentrated in the dust collection drawer 15. After cleaning, the worker slides the dust collection drawer 15 straight into the guide groove 6 along the track inside the guide groove 6. As the dust collection drawer 15 gradually slides into the guide groove 6, the locking block 19 also enters the fixed box 20. As the locking block 19 moves, when it reaches the position of the limit block 22, the limit spring 21 pushes the limit block 22 into the side wall of the locking block 19, thus fixing the dust collection drawer 15 and achieving the effect of quickly and centrally cleaning aluminum powder. When aluminum powder needs to be cleaned again, the above operation can be repeated.

[0039] Working Principle: When using this automated aluminum cylinder surface polishing equipment, the robotic arm 2 first drives the base 7 to rotate and shift, aligning the connecting plate 8 with one end of the aluminum cylinder 4 located above the support 3. Then, the connecting plate 8 is inserted into the aluminum cylinder 4. At this time, the electric pusher 9 at the bottom of the connecting plate 8 pushes the push rod 10 downwards. The displacement of the push rod 10 causes the movable block 11 to also move downwards. The displacement of the movable block 11 further drives the multiple connecting seats 12 on its outer wall to move synchronously, thereby causing the connecting arm 13 to rotate. Through the cooperation of the multiple connecting seats 12 on the outer wall of the electric pusher 9 and the connecting arm 13, multiple movable plates 14 unfold and press against the inner wall of the aluminum cylinder 4, allowing the robotic arm 2 to move the aluminum cylinder 4. Subsequently, the aluminum cylinder 4 is placed on one side of the polishing machine 5 for grinding and polishing, thus achieving the effect of quickly fixing aluminum cylinders 4 with different inner diameters. During the grinding and polishing process, a large amount of aluminum powder is generated. At this time, the aluminum cylinder 4 located on the base 7 is polished. The negative pressure fan 18 inside the bottom air duct 17 of the polishing machine 5 starts working to generate negative pressure, which draws aluminum powder from the air into the guide groove 6 and blocks it outside the filter plate 16. After the work is completed, the aluminum powder is concentrated inside the dust collection tray 15. At this time, the operator can manually pull the dust collection tray 15 outward through the handle on the side wall of the dust collection tray 15. At this time, the locking block 19 on one side of the dust collection tray 15 also moves outward, which causes the limiting block 22 on its side wall to be retracted into the fixed box 20, thereby compressing the limiting spring 21. After the locking block 19 is disengaged from the limiting block 22, the operator can take out the dust collection tray 15 and clean the concentrated aluminum powder. After cleaning, the dust collection tray 15 is slid into the guide groove 6 along the track. At this time, the locking block 19 is inserted into the fixed box 20, and the limiting spring 21 pushes the limiting block 22 into the side wall of the locking block 19, thus completing the fixation of the dust collection tray 15, thereby achieving the effect of quickly and centrally cleaning aluminum powder.
