Abstract

This invention relates to the field of aluminum alloy production technology and discloses a high-strength aluminum alloy casting production line, including a support frame with a transmission chain for the production line. After the aluminum alloy is cast, it is transported by the transmission chain. A transmission belt is provided on the power shaft of the transmission chain, and a lifting block is provided on the transmission belt. A lifting assembly is provided on the support frame, and the lifting assembly includes a lifting frame and a force-saving plate. When the lifting block moves, it continues to drive the lifting frame to move upward and contact the bottom end of the aluminum alloy, separating it from the transmission chain. This prevents the aluminum alloy from being worn by the transmission chain while waiting to be unloaded. This invention uses a dual-drive structure of lifting triggered by the force-saving plate and continuous pushing by the lifting block, so that the aluminum alloy can be lifted by the lifting frame and completely separated from the transmission chain before waiting for the robot to grab and unload it. This avoids friction caused by the continuous operation of the transmission chain while the aluminum alloy is waiting on the transmission chain, which would lead to surface or edge wear, thus ensuring the integrity of the aluminum alloy casting.

Description

Technical Field

[0001] This invention relates to the field of aluminum alloy production technology, specifically to a high-strength aluminum alloy casting production line. Background Technology

[0002] Aluminum alloy is a lightweight metal material synthesized by adding a certain amount of other metals to aluminum. In the field of aluminum alloy casting production, the aluminum alloy castings after casting need to be conveyed through the production line to realize the flow from the casting process to subsequent material cutting, inspection, and processing. Among them, the stable conveying and efficient material cutting of the castings on the transmission chain are the key links to ensure production continuity, product qualification rate and production efficiency.

[0003] After aluminum alloy castings fall from the casting device onto the transmission chain, they need to be transported to the designated unloading area by the transmission chain. The robotic arm then picks up the castings in batches and packages them in the unloading area. Since the robotic arm needs to wait for a certain number of castings to accumulate on the transmission chain for each pick, the castings that arrive at the unloading area first need to stay on the transmission chain and wait. In order to ensure production continuity, the transmission chain is usually in a continuous running state. The bottom of the castings that are staying on the transmission chain is always in contact with the surface of the transmission chain. Under the continuous friction of the transmission chain, the bottom of the castings is prone to scratches, wear, and even deformation. Summary of the Invention

[0004] The purpose of this invention is to provide a high-strength aluminum alloy casting production line to solve the problems mentioned in the background art.

[0005] Technical solution

[0006] This invention provides the following technical solution: a high-strength aluminum alloy casting production line, comprising a support frame, on which a transmission chain for the production line is installed. After the aluminum alloy is cast, it is transported by the transmission chain. A transmission belt is installed on the power shaft of the transmission chain, and a lifting block is installed on the transmission belt. A lifting assembly is installed on the support frame, and the lifting assembly includes a lifting frame and a force-saving plate. When the aluminum alloy is transported by the transmission chain, after contacting the force-saving plate, the force-saving plate rotates and drives the lifting frame to move upward a certain distance. Subsequently, as the lifting block moves, it continues to drive the lifting frame upward to contact the bottom end of the aluminum alloy, and continues to drive the lifting frame upward so that the aluminum alloy separates from the transmission chain, preventing the aluminum alloy from being worn by the transmission chain while waiting to be unloaded.

[0016] Beneficial effects

[0017] Compared with the prior art, the present invention provides a high-strength aluminum alloy casting production line, which has the following beneficial effects:

[0018] 1. In this invention, the dual drive structure of lifting triggered by the labor-saving plate and continuous pushing by the lifting block enables the aluminum alloy to be lifted by the lifting frame and completely separated from the transmission chain before waiting for the robot to grab and unload it. This avoids friction caused by the continuous operation of the transmission chain while the aluminum alloy is waiting on the transmission chain, which would lead to surface or edge wear and ensure the integrity of the aluminum alloy casting.

[0019] 2. In this invention, the limiting plate at the top of the lifting frame has an inclined surface, which can automatically align the aluminum alloy on the transmission chain during the lifting process. This avoids collisions between the aluminum alloy being transported and the aluminum alloy to be unloaded, and also prevents damage to the aluminum alloy caused by positional deviation. This further ensures the appearance and structural accuracy of the castings and improves the product qualification rate.

[0035] 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.

[0036] Example:

[0037] Please see Figures 1-10 This invention provides a technical solution: a high-strength aluminum alloy casting production line, including a support frame 1, on which a transmission chain 8 for the production line is installed. After the aluminum alloy is molded, it is transported by the transmission chain 8. A transmission belt 7 is movably installed on the power shaft of the transmission chain 8. Lifting blocks 23 are fixedly installed at equal intervals on the transmission belt 7. A lifting assembly is provided on the support frame 9. The lifting assembly includes a lifting frame 3 and a force-saving plate 4. When the aluminum alloy is transported by the transmission chain 8, after touching the force-saving plate 4, the force-saving plate 4 rotates and drives the lifting frame 3 to move upward a certain distance. Subsequently, when the lifting block 23 moves, it will continue to drive the lifting frame 3 to move upward and contact the bottom end of the aluminum alloy, and continue to drive the lifting frame 3 to move upward so that the aluminum alloy is separated from the transmission chain 8, preventing the aluminum alloy from being worn by the transmission chain 8 while waiting for unloading.

[0038] In this embodiment, a baffle 2, a fixed frame 5, and a support frame 9 are fixedly installed on the support frame 1. The baffle 2 is located above the support frame 9 and on the side of the lifting frame 3. The baffle 2 can block the aluminum alloy from moving forward, making it easier for the robot to clamp and unload multiple aluminum alloys on the transmission chain 8. The fixed frame 5 is located on the side of the support frame 1, the lifting component is located on the side of the baffle 2, and the support frame 9 is located below the lifting frame 3. The support frame 9 is movably connected to the lifting frame 3 through a fixed column 14 fixedly installed at the top. At the same time, the width of the lifting frame 3 and the support frame 9 are equal, and are also equal to the width of the produced aluminum alloy.

[0039] In this embodiment, a fixed column 14 is movably installed inside the lifting frame 3. The fixed column 14 is T-shaped, and its top end slides in contact with the actuating plate 22. A first fixed shaft 17 is fixedly installed inside the lifting frame 3. The fixed column 14 is located below the first fixed shaft 17 and does not contact the first fixed shaft 17. A rotating column 18 is movably installed on the first fixed shaft 17. The rotating column 18 passes through the inner walls of the two symmetrical sides of the lifting frame 3 and extends outward. A first rotating gear 21 is fixedly installed on the outer side of the rotating column 18 of the lifting frame 3, while the actuating plate 22 is fixedly installed on the inner side of the rotating column 18 of the lifting frame 3. At the same time, the labor-saving plate 4 is also fixedly installed on the outer side of the rotating column 18 of the lifting frame 3.

[0040] In this embodiment, the top of the lifting frame 3 is provided with a connecting groove 19 that matches the actuating plate 22. The connecting groove 19 is for the convenience of rotating the actuating plate 22. When the actuating plate 22 is not working, it is located in the connecting groove 19. A limiting plate 16 is fixedly installed on the top surface of the lifting frame 3. An inclined surface is provided on the limiting plate 16. When the limiting plate 16 rises, the limiting plate 16 can straighten the aluminum alloy located on the transmission chain 8 through the inclined surface, which is convenient for the unloading robot to clamp and unload the material. At the same time, it can also prevent damage from subsequent collisions with the aluminum alloy. The limiting plate 16 is located on the side of the connecting groove 19, and the height of the limiting plate 16 is less than the length of the labor-saving plate 4. The fixing column 14 passes through the bottom wall of the lifting frame 3 and is fixedly connected to the support frame 9.

[0041] When the lifting frame 3 moves upward, the actuating plate 22 will increase the angle between itself and the fixed column 14 after contacting the fixed column 14, until the lifting frame 3 moves upward to the maximum distance, at which point the actuating plate 22 and the fixed column 14 are perpendicular.

[0042] In this embodiment, a lifting plate 11 is fixedly installed on the side of the lifting frame 3, and a sliding toothed plate 15 is movably installed. The lifting plate 11 is located below the sliding toothed plate 15. The sliding toothed plate 15 can slide on the side of the lifting frame 3 without contacting the lifting plate 11. A first toothed column 10 is fixedly installed on each sliding toothed plate 15, and a first rotating gear 21 meshes with the first toothed column 10.

[0043] The first rotating gear 21 is a semi-circular arc gear. The position of the first tooth post 10 on each sliding tooth plate 15 is different. At the same time, the position of the corresponding first rotating gear 21 on each lifting frame 3 is also different. When the sliding tooth plate 15 on the first lifting frame 3 is meshed and rotated by the first rotating gear 21, the first tooth post 10 on the sliding tooth plate 15 in the second lifting frame 3 will mesh and contact with its corresponding first rotating gear 21, and so on.

[0044] In this embodiment, the lifting block 23 slides in contact with the lifting plate 11. The contact sides of the lifting block 23 and the lifting plate 11 are respectively provided with a second inclined surface 25 and a first inclined surface 24. When the lifting plate 11 moves upward, the lifting block 23 will slide in contact with the first inclined surface 24 of the lifting plate 11 through the second inclined surface 25. As the lifting plate 11 continues to move, the lifting block 23 can drive the lifting plate 11 to continue to rise through the second inclined surface 25 and the first inclined surface 24. That is, the lifting frame 3 can move upward under the action of the lifting block 23. The lifting frame 23 can contact the bottom end of the aluminum alloy and drive the aluminum alloy to move upward, so that the bottom end of the aluminum alloy is separated from the transmission chain 8. In this way, when the aluminum alloy is waiting to be picked up by the robot, the aluminum alloy that was waiting on the transmission chain 8 can avoid being worn by the continuously working transmission chain 8, ensuring the integrity of the aluminum alloy and ensuring the pass rate of the aluminum alloy.

[0045] In this embodiment, a push cylinder 20 is fixedly installed inside the support frame 9. The output shaft of the push cylinder 20 passes through the support frame 9 and a push plate 13 is fixedly installed thereon. The push plate 13 is always located on the outside of the support frame 9 and is located on the side of the support frame 9 away from the baffle 2. At the same time, the push plate 13 is in contact with the sliding toothed plate 15 at the last position. Only after all the lifting frames 3 are lifted will the sliding toothed plate 15 at the last position contact the push plate 13. A connecting block 12 is fixedly installed at the bottom of the support frame 9 and the outside of the support frame 1, respectively. The connecting rope 26 passes through the two connecting blocks 12 in sequence and slides in contact with the connecting blocks 12. The connecting rope 26 is a steel cable.

[0046] In this embodiment, a connecting rope 26 is slidably disposed on the connecting block 12. One end of the connecting rope 26 passes through the symmetrical inner wall of the support frame 9 and is fixedly connected to the bottom end of the lifting frame 3. The other end of the connecting rope 26 passes through the bottom inner wall of the fixed frame 5 and extends into the fixed frame 5. After extending into the fixed frame 5, it is fixedly connected to the bottom end of the sliding plate 30.

[0047] In this embodiment, an elastic element 31 is fixedly installed at the bottom end of the sliding plate 30. The elastic element 31 is a reset spring, which is located inside the fixed frame 5. A second toothed post 29 is fixedly installed at the top end of the sliding plate 30, and the second toothed post 29 passes through the top end of the fixed frame 5 and extends out of the fixed frame 5.

[0048] In this embodiment, a second fixed shaft 27 is fixedly installed at the bottom of the fixed frame 5. A limit rod 6 and a second rotating gear 28 are movably installed on the second fixed shaft 27. The limit rod 6 and the second rotating gear 28 are fixedly connected. The second gear 29 is meshed with the second rotating gear 28. The limit rod 6 is T-shaped and can rotate around the second fixed shaft 27. When the limit rod 6 is above the support frame 1, the limit rod 6 is above the aluminum alloy. At this time, the part of the limit rod 6 above the aluminum alloy is set as an inverted "Z" shape. That is, the closer to the baffle 2, the higher the height of the limit rod 6 begins to rise. The height of the part of the limit rod 6 above the lifting frame 3 is the same. At this time, the limit rod 6 can provide an upper limit for the aluminum alloy when the lifting frame 3 is lifted, so that several aluminum alloys in the stopped state have the same height, which is convenient for the robot to grip. At the same time, when the limit rod 6 rotates to the side of the support frame 1, the robot can grip and unload several aluminum alloys on the lifting assembly.

[0049] When the aluminum alloy is lifted, it can prevent the aluminum alloy from being continuously operated by the transmission chain 8, thus preventing the aluminum alloys from colliding with each other. At the same time, when the aluminum alloy is lifted, a larger gap will be created between the side of the aluminum alloy and the transmission chain 8, increasing the contact area between the unloading robot and the aluminum alloy, making it easier for the unloading robot to grasp and unload the material. The unloading robot can more firmly fix and clamp the aluminum alloy.

[0050] When the labor-saving plate 4 initially contacts the aluminum alloy, it can be lifted by rotating to reduce the impact force of the aluminum alloy on the component. Subsequently, the lifting block 23 pushes the lifting plate 11 through the sliding contact of the first inclined surface 24 and the second inclined surface 25. The transmission is smooth and the force is even, avoiding damage to the component due to excessive instantaneous force.

[0051] The effort-saving plate 4 on the first lifting frame 3 near the baffle 2 is perpendicular to the lifting frame 3. The first rotating gear 21 and the sliding tooth plate 15 on the first lifting frame 3 are in a meshing connection state. The first rotating gear 21 and the sliding tooth plate 15 on the subsequent lifting frames 3 are not in a meshing connection state.

[0052] By using the design of the semi-circular first rotating gear 21 and the staggered first toothed column 10, multiple lifting frames 3 are triggered sequentially to complete the lifting action, avoiding positional interference caused by the simultaneous lifting of multiple aluminum alloys, ensuring that the aluminum alloys are stacked in an orderly manner on the conveyor line and lifted one by one, which is compatible with the rhythm of the robot arm's batch grasping.

[0053] When the last lifting frame 3 completes its lifting, the sliding plate 30 and the second toothed column 29 inside the fixed frame 5 are linked by the connecting rope 26, which drives the second rotating gear 28 to rotate the limit rod 6 above the aluminum alloy. The "reverse Z-shaped" structure of the limit rod ensures that all the lifted aluminum alloys maintain the same height, solving the problem of difficulty in gripping and low efficiency of the robot arm due to inconsistent stacking height of aluminum alloys in traditional production lines. This allows the robot arm to quickly and accurately clamp and unload materials in batches, shortening the unloading cycle.

[0054] After the aluminum alloy is lifted, its side forms a large gap with the transmission chain 8. Compared with the traditional state of being attached to the transmission chain, the contact space between the robot and the aluminum alloy is more sufficient and the contact area is larger. This allows for a more secure clamping of the aluminum alloy, reducing the risk of castings falling off during the gripping process and meeting the stable operation requirements of automated production lines.

[0055] The working principle of this embodiment is as follows: When the aluminum alloy is dropped from the molding device onto the transmission chain 8 for transportation, the first aluminum alloy stops moving under the action of the baffle 2 and waits for the subsequent aluminum alloys to accumulate, so that it can be picked up and unloaded by the unloading robot.

[0056] When the first aluminum alloy moves towards the baffle 2 under the action of the transmission chain 8, it will contact the force-saving plate 4 on the first lifting frame 3 and cause the force-saving plate 3 to tilt towards the baffle 2. At the same time, when the force-saving plate 3 tilts, it will cause the rotating column 18 to rotate around the first fixed shaft 17. Moreover, when the rotating column 18 rotates, it will also drive the first rotating gear 21 to rotate. The first rotating gear 21 will drive the sliding tooth plate 15 to move towards the second lifting frame 3 through the first tooth column 10, and move towards the third lifting frame 3 together with the sliding tooth plate 15 on the second lifting frame 3. This causes the force-saving plate 3 on the second lifting frame 3 to rotate from a state parallel to the lifting frame 3 to a state perpendicular to the second lifting frame 3. The actuating plate 22 in the second lifting frame 3 rotates into the interior of the second lifting frame 3 through the connecting groove 19. Moreover, when the rotating column 18 rotates in the first lifting frame 3, it will also drive its corresponding actuating plate 22 to rotate. When the actuating plate 22 rotates, it will contact the fixed column 17. When the top of the first aluminum alloy is in contact with the top of the first aluminum alloy, the first lifting frame 3 will move upward until it contacts the bottom of the first aluminum alloy. At this time, the lifting block 23 on the transmission belt 7 contacts the lifting plate 11 on the first lifting frame 3. As the transmission belt 7 rotates, the lifting block 23 will drive the lifting plate 11 to move upward through the second inclined surface 25 and the first inclined surface 24. The lifting plate 11 is fixedly installed on the lifting frame 3. In this way, the lifting frame 3 will continue to move upward and drive the first aluminum alloy to move upward and separate from the transmission chain 8. This prevents the first aluminum alloy from being damaged by the continuous movement of the transmission chain 8 when waiting for the subsequent aluminum alloy to accumulate, thus preventing wear. At the same time, when the first aluminum alloy has completed the lifting work, the second aluminum alloy will contact the force-saving plate 4 on the second lifting frame 3 and start lifting the first aluminum alloy again. The subsequent ones are like this until the aluminum alloy on the last lifting frame 3 has completed the lifting work.

[0057] At the same time, when the last side lifting frame 3 is lifted, it will drive the connecting rope 26 to move upward, and cause the sliding plate 30 in the fixed frame 5 to move downward, squeezing the elastic element 31. Moreover, the sliding plate 30 will also drive the second toothed column 29 to move downward together. When the second toothed column 29 moves downward, it will drive the limiting rod 6 to rotate through the second rotating gear 28. The limiting rod 6 will rotate around the second fixed axis 27. After the limiting rod 6 rotates, it will rotate with the aluminum alloy above it until it is perpendicular to the support frame 1. This makes it easier for the subsequent unloading robot to grab and unload the aluminum alloy of the lifting component.

[0058] After the last lifting frame 3 completes its upward movement, its corresponding sliding toothed plate 15 will contact the push plate 13. When the aluminum alloy on the lifting assembly is gripped, the push cylinder 20 will drive the push plate 13 to move. The push plate 13 will drive the sliding toothed plate 15 to move towards the baffle 2. When the sliding toothed plate 15 moves, it will drive the rotating column 18 to reverse on the first fixed shaft 17 through the first rotating gear 21. After the rotating column 18 reverses, it will drive the actuating plate 22 to rotate in the opposite direction. When the actuating plate 22 rotates, it will cause the lifting frame 3 to move downward with the cooperation of the fixed column 14 until the lifting frame 3 is in complete contact with the support frame 9, that is, the lifting assembly has completed its downward movement, so that the aluminum alloy can be re-cut.

[0059] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
