Description

Technical Field

[0001] This invention belongs to the field of aluminum round rod oxide layer removal technology, and specifically relates to an aluminum round rod surface oxide layer removal device. Background Technology

[0002] In the industrial manufacturing sector, concave conical hollow aluminum rods are widely used in aerospace, automotive parts, electronic equipment, and other key fields due to their lightweight, high strength, and excellent mechanical properties. With the continuous growth of market demand, the production scale of concave conical hollow aluminum rods is constantly expanding, and batch production efficiency and product quality stability have become the core focus of the industry. Among these, the removal of the surface oxide layer is a crucial preliminary process to ensure the subsequent processing accuracy, assembly performance, and service life of the aluminum rods; its treatment effect and processing efficiency directly affect the smoothness of the overall production process. Currently, the industry still widely uses traditional manual grinding methods to remove the oxide layer from the surface of concave conical hollow aluminum rods. This method requires workers to manually and precisely place each aluminum rod into the processing station of a special grinding machine. After the oxide layer of each aluminum rod is ground, it is then manually removed one by one. This process relies entirely on manual intervention, which is not only cumbersome but also requires a large investment of manpower and time. Furthermore, the stability of manual operation is easily affected by subjective factors, increasing the risk of incomplete oxide layer removal or damage to the surface of the aluminum rod. Therefore, we propose a device for removing the oxide layer from the surface of aluminum round rods. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a device for removing the oxide layer from the surface of aluminum round rods.

[0004] To achieve the above objectives, the present invention provides an aluminum round rod surface oxide layer removal device, comprising a feeding hopper and multiple aluminum round rods placed inside it. A platform is fixedly connected to the bottom of the feeding hopper via a mounting plate. A concave seat is fixedly connected to the middle of the upper end of the platform near the front and rear edges. The upper ends of the two concave seats are connected to a second electric push rod via a drive mechanism. A motor is fixedly connected to the telescopic shaft end of the two second electric push rods. An expansion mechanism is provided at the rotating shaft end of the two motors. A grinding mechanism is provided at the upper end of the platform. Two sets of front-to-back symmetrical limiting components are provided on the inner sidewall of the feeding hopper near the lower edge.

[0005] In the above technical solution, the driving mechanism further includes a first electric push rod, which is fixedly connected to the middle of the inner bottom end of the concave seat, and a block is fixedly connected to the telescopic shaft end of the first electric push rod. The block slides against the inner wall of the concave seat, and the upper end of the block is fixedly connected to the lower end of the second electric push rod.

[0006] In the above technical solution, the expansion mechanism further includes a cylinder, the outer wall of which is fixedly connected to the center of the horizontal plane of the cylinder to the rotating shaft end of the motor, and the inner horizontal plane of the cylinder is fixedly connected to a third electric push rod. The telescopic shaft end of the third electric push rod is fixedly connected to a conical block. The rear end of the cylinder is fixedly connected to a disc. The front and rear ends of the disc are provided with multiple sliding grooves around its axis. The inner sides of the multiple sliding grooves are slidably fitted with strip columns. The multiple strip columns are connected to the conical block by sliding parts, and the ends of the multiple strip columns that are far apart from each other are fixedly connected with anti-slip strips. The axis of the disc is consistent with the axis of the lowest aluminum rod in the feeding hopper.

[0007] In the above technical solution, the sliding member further includes multiple trapezoidal grooves and multiple trapezoidal blocks. The multiple trapezoidal grooves are respectively opened on the outer inclined surface of the conical block around the axis of the conical block. The multiple trapezoidal blocks are respectively fixedly connected to the end inclined surface of multiple strip columns near the side of the conical block, and the multiple trapezoidal blocks and the multiple trapezoidal grooves are in sliding engagement.

[0008] In the above technical solution, the grinding mechanism further includes an inclined plate, which is fixedly installed on the upper center of the table by a mounting base. Electric rollers are rotatably installed on the upper inclined surface of the inclined plate near the upper and lower edges. The outer walls of the two electric rollers are jointly fitted with a sandpaper belt, which is located directly below the discharge port below the feeding hopper.

[0009] In the above technical solution, the limiting component further includes a concave block, which is fixedly connected to the outer wall of one side of the feeding hopper near the lower edge. A square column is movably passed through the middle of the outer wall of the concave block. A triangular block is fixedly connected to the end of the square column near the feeding hopper. Both the triangular block and the square column are movably passed through the outer wall of the feeding hopper. The inclined surface of the triangular block is in contact with the outer wall of the lowest aluminum rod inside the feeding hopper. A square plate is fixedly sleeved on the outer wall of the square column. The square plate is in contact with the outer wall of the feeding hopper. A spring is fixedly connected between the square plate and the inner wall of the concave block. The spring is slidably sleeved on the outer wall of the square column.

[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the coordinated operation of the feeding hopper, table, concave seat, drive mechanism, second electric push rod, motor, expansion mechanism, grinding mechanism, and limiting components, this device can accommodate multiple concave conical hollow aluminum rods at once, eliminating the need for workers to place them one by one, thus significantly reducing preparation time. Secondly, after startup, the device automatically grinds each rod individually without manual intervention, breaking the limitations of traditional single-rod grinding, significantly improving grinding efficiency, and adapting to mass production scenarios. Finally, after grinding, workers only need to focus on collecting the finished product, eliminating the repetitive and tedious "place-grind-remove" operation of traditional methods, reducing labor intensity, decreasing the probability of human error, and improving the efficiency and quality of grinding and removing the oxide layer from the surface of the concave conical hollow aluminum rods. 2. This device not only optimizes the operation process for removing the oxide layer from concave conical hollow aluminum rods, but also plays an important role in improving production efficiency, saving labor costs, and reducing labor intensity, providing an efficient and convenient solution for mass production.

Detailed Implementation To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0013] like Figures 1-6The device for removing the oxide layer on the surface of aluminum round rods shown includes a feeding hopper 2 and multiple aluminum round rods 3 placed inside it. A platform 1 is fixedly connected to the bottom of the feeding hopper 2 via a mounting plate. A concave seat 4 is fixedly connected to the middle of the upper end of the platform 1 near the front and rear edges. The upper ends of the two concave seats 4 are connected to a second electric push rod 7 via a drive mechanism. A motor 8 is fixedly connected to the telescopic shaft end of the two second electric push rods 7. An expansion mechanism is provided at the rotating shaft end of the two motors 8. A grinding mechanism is provided at the upper end of the platform 1. Two sets of front and rear symmetrical limiting components are provided on the inner side wall of the feeding hopper 2 near the lower edge.

[0014] The drive mechanism includes a first electric push rod 5, which is fixedly connected to the middle of the inner bottom end of the concave seat 4. A block 6 is fixedly connected to the telescopic shaft end of the first electric push rod 5. The block 6 slides against the inner wall of the concave seat 4, and the upper end of the block 6 is fixedly connected to the lower end of the second electric push rod 7.

[0015] The expansion mechanism includes a cylinder 9. The outer horizontal plane of the cylinder 9 is fixedly connected to the rotating shaft end of the motor 8, and the inner horizontal plane of the cylinder 9 is fixedly connected to a third electric push rod 17. The telescopic shaft end of the third electric push rod 17 is fixedly connected to a conical block 14. The rear end of the cylinder 9 is fixedly connected to a disc 10. The front and rear ends of the disc 10 are provided with multiple sliding grooves 13 around its axis. The inner sides of the multiple sliding grooves 13 are all slidably attached to strip columns 11. The multiple strip columns 11 are connected to the conical block 14 through sliding parts, and the ends of the multiple strip columns 11 that are far apart from each other are fixedly connected to anti-slip strips 12. The axis of the disc 10 is consistent with the axis of the lowest aluminum rod 3 in the feeding hopper 2.

[0016] The sliding component includes multiple trapezoidal grooves 15 and multiple trapezoidal blocks 16. The multiple trapezoidal grooves 15 are respectively opened on the outer inclined surface of the conical block 14 around the axis of the conical block 14. The multiple trapezoidal blocks 16 are respectively fixedly connected to the end inclined surface of multiple strip columns 11 near the side of the conical block 14, and the multiple trapezoidal blocks 16 and the multiple trapezoidal grooves 15 are in sliding engagement.

[0017] The grinding mechanism includes an inclined plate 23, which is fixedly installed in the upper middle part of the table 1 by a mounting base. Electric rollers 24 are rotatably installed on the upper inclined surface of the inclined plate 23 near the upper and lower edges. The outer walls of the two electric rollers 24 are fitted with a sandpaper belt 25, which is located directly below the discharge port below the feeding hopper 2.

[0018] The limiting component includes a concave block 18, which is fixedly connected to the outer wall of the feeding hopper 2 near the lower edge. A square post 22 is movably passed through the middle of the outer wall of the concave block 18. A triangular block 19 is fixedly connected to the end of the square post 22 near the feeding hopper 2. Both the triangular block 19 and the square post 22 are movably passed through the outer wall of the feeding hopper 2. The inclined surface of the triangular block 19 is in contact with the outer wall of the lowest aluminum rod 3 inside the feeding hopper 2. A square plate 20 is fixedly sleeved on the outer wall of the square post 22. The square plate 20 is in contact with the outer wall of the feeding hopper 2. A spring 21 is fixedly connected between the square plate 20 and the inner wall of the concave block 18. The spring 21 is slidably sleeved on the outer wall of the square post 22.

[0019] Working principle: When it is necessary to polish the oxide layer on the outer wall of multiple aluminum round rods 3, first, the multiple aluminum round rods 3 are placed into the feeding hopper 2 in sequence (e.g., Figure 1 As shown), the aluminum rod 3 is a concave conical hollow shape.

[0020] Subsequently, the two second electric push rods 7 are simultaneously connected to an external power source. The telescopic shaft ends of the two second electric push rods 7 extend outward, which can drive the corresponding two motors 8 to move towards each other. The two motors 8 can drive the two sets of expansion mechanisms to move towards each other synchronously until the three corresponding strip columns 11 on the two discs 10 are inserted into the inner walls of both ends of the aluminum rod 3.

[0021] Subsequently, the two third electric push rods 17 are connected to an external power source. The telescopic shaft ends of the two third electric push rods 17 can drive the corresponding two conical blocks 14 to move towards each other. The two conical blocks 14 can drive the corresponding multiple trapezoidal blocks 16 to slide inside the corresponding multiple trapezoidal grooves 15 and expand outward along the axis of the trapezoidal grooves 15. The multiple trapezoidal blocks 16 can drive the corresponding multiple strip columns 11 and multiple anti-slip strips 12 to expand outward until the anti-slip strips 12 on the outer walls of the three corresponding strip columns 11 on the two discs 10 are tightly fitted with the inner walls of the front and rear ends of the bottom aluminum round rod 3.

[0022] Next, connect the two electric rollers 24 to an external power source. The two electric rollers 24 can drive the sandpaper belt 25 to rotate slowly. At the same time, connect the two motors 8 to an external power source. The two motors 8 can drive the expansion mechanism and the corresponding aluminum rod 3 to rotate synchronously. Then, connect the first electric push rod 5 to an external power source. The telescopic shaft end of the first electric push rod 5 can drive the block 6 to move downward along the inner wall of the concave seat 4. The block 6 can drive the second electric push rod 7, the motor 8, and the expansion mechanism to move downward synchronously. The expansion mechanism can drive the corresponding aluminum rod 3 to move downward.

[0023] When the expansion mechanism moves the corresponding aluminum rod 3 downwards, during this process, the aluminum rod 3 will press the two triangular blocks 19 to both sides along the inclined surfaces of the two triangular blocks 19. The two triangular blocks 19 can drive the two square pillars 22 and the two square plates 20 to move synchronously. The two square plates 20 can press the spring 21 between the two concave blocks 18 until the two triangular blocks 19 disengage from the aluminum rod 3 moved downwards by the expansion mechanism. Then, under the force of the spring 21, the two triangular blocks 19 can be reset. At the same time, the aluminum rod 3 inside the feeding hopper 2 will move downwards due to gravity until the lowest aluminum rod 3 inside the feeding hopper 2 is in contact with the inclined surfaces of the two triangular blocks 19 (e.g., Figure 1 (As shown).

[0024] Until the expansion mechanism drives the corresponding aluminum rod 3 downward to fully fit the sandpaper belt 25 (the concave conical outer wall of the aluminum rod 3 can compress the sandpaper belt 25 to deform, so that the outer surface of the sandpaper belt 25 can fully fit the concave conical outer wall of the aluminum rod 3), at the same time, the two motors 8 drive the corresponding aluminum rod 3 to rotate rapidly to generate friction with the outer surface of the sandpaper belt 25. This process can remove the oxide layer on the outer surface of the aluminum rod 3.

[0025] After the oxide layer on the outer surface of the corresponding aluminum rod 3 is cleaned by friction, the two electric rollers 24 are disconnected from the external power supply. Then, the sandpaper belt 25 can stop rotating. Subsequently, the two motors 8 are disconnected from the external power supply. At the same time, the telescopic shaft ends of the two third electric push rods 17 are retracted inward, which can drive the corresponding multiple strip columns 11 to reset. Finally, the telescopic shaft ends of the two second electric push rods 7 are retracted inward, which can drive the two sets of expansion mechanisms to move in a direction away from each other until the corresponding aluminum rod 3 is completely separated from the expansion mechanism. Then, the polished aluminum rod 3 can roll down the inclined surface of the sandpaper belt 25. Finally, the rolled aluminum rod 3 can be collected.

[0026] By repeating this process, the multiple aluminum rods 3 with oxide layers on their surfaces inside the feeding hopper 2 can be ground and removed in sequence.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
