Description

Technical Field

[0001] This utility model relates to the field of wheel hub blank stacking technology, specifically a wheel hub blank stacking device. Background Technology

[0002] In the wheel manufacturing process, as the scale of wheel production continues to expand, a large number of wheel blanks, if not stacked, will occupy a huge amount of production space, causing workshop chaos, hindering the orderly progress of the production process, and affecting production efficiency. In the subsequent processing and transportation stages, if the blanks are not neatly stacked, it will greatly reduce the efficiency of finding and retrieving them, which is not conducive to the accurate execution of the production plan. Therefore, stacking wheel blanks can ensure high production efficiency and stable product quality.

[0003] Traditional manual production lines require relatively small initial investments, but as market demand expands, their inefficiencies and inconsistent product quality increasingly hinder business development. Automated production lines can solve these problems, offering higher production efficiency, stable product quality, and lower unit production costs under large-scale production conditions. The advantages of automated stamping production lines are particularly pronounced for the production of large automotive wheel hub blanks. Therefore, large wheel hub manufacturers now typically consider automation when planning large stamping production lines, and a wheel hub blank stacking device is proposed to address the aforementioned issues.

[0015] Compared with the prior art, this utility model provides a wheel hub blank stacking device, which has the following features:

[0016] Beneficial effects:

[0017] 1. This wheel hub blank stacking device, through the cooperation of a non-standard chain conveying mechanism, a spacing adjustment mechanism, a tensioning mechanism and a drive assembly, drives a motor to rotate gear one, which in turn causes gear two to rotate in tandem via a chain, thus achieving stable conveying of wheel hub blanks by the non-standard chain conveying mechanism. At the same time, the rotation of the bidirectional threaded rod of the spacing adjustment mechanism drives the moving frame to move, thereby adjusting the spacing of the non-standard chain conveying mechanism to adapt to the transmission of wheel hub blanks of different specifications. The spring and sliding block structure of the tensioning mechanism ensures that the chain always maintains appropriate tension, preventing the chain from loosening or falling off, effectively improving the stability and compatibility of blank transmission, and ensuring the efficient operation of the stacking process;

[0018] 2. This wheel hub blank stacking device, through the cooperation of a material dropping mechanism, a buffer mechanism, and a blank collection mechanism, when the blanks on the receiving conveyor support reach a certain quantity, the material dropping cylinder pushes the material dropping rod, causing the blanks to fall to the buffer mechanism. The buffer plate, supported by the buffer cylinder, receives the blanks, effectively buffering the impact force of the falling blanks and preventing damage. Then, the buffer cylinder is driven to pull the buffer plate away, allowing the blanks to fall smoothly onto the blank rack, avoiding the risk of damage caused by a single drop. The collection cylinder of the blank collection mechanism drives the fixed rod to move the blank rack in a timely manner, facilitating the removal of the rack filled with blanks by a forklift or overhead crane. The entire process is automated, greatly saving manpower, eliminating the safety hazards caused by manual stacking, improving production efficiency and product quality stability, and meeting the needs of large-scale production in enterprises.

Detailed Implementation

[0026] 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.

[0027] Please see Figures 1-4 In this embodiment: a wheel hub blank stacking device includes a material carrying bracket 1, a plurality of support rods 2 are fixedly connected to the top of the material carrying bracket 1, a receiving conveying bracket 3 is fixedly connected to the top of the plurality of support rods 2, and two slide rails 4 are fixedly connected to the bottom of the receiving conveying bracket 3, and two sliders 5 are slidably connected to the bottom of each of the two slide rails 4.

[0028] Specifically, the material support bracket 1 is used to support the entire equipment, the support rod 2 connects the material support bracket 1 and the receiving conveyor bracket 3, and plays the role of supporting the receiving conveyor bracket 3. The cooperation of the slide rail 4 and the slider 5 allows the non-standard chain conveyor mechanism 6 to adjust its position below the receiving conveyor bracket 3.

[0029] Multiple sliders 5 are equipped with non-standard chain conveying mechanisms 6 at their bottoms. The non-standard chain conveying mechanisms 6 include two support plates 601, which are fixedly connected to the bottoms of the two sliders 5. A gear 602 is rotatably connected to the bottom left side of the support plate 601, and a gear 603 is slidably connected to the bottom right side of the support plate 601. A chain 604 is sleeved around the outer periphery of the gear 602 and the gear 603. A drive assembly 7 is provided on the top left side of the support plate 601. The drive assembly 7 includes a motor frame 701, which is fixedly connected to the top left side of the support plate 601. A drive motor 702 is fixedly connected to the top of the motor frame 701, and the output end of the drive motor 702 is fixedly connected to the top of the gear 602.

[0030] Specifically, the support plate 601 provides support for other parts of the non-standard chain conveyor mechanism 6. Gear 1 602 and Gear 2 603 cooperate with the chain 604 to achieve stable transmission of the wheel hub blank under the power drive of the drive motor 702. The motor frame 701 is used to fix the drive motor 702 to ensure the stability of the drive motor 702 during operation. The drive motor 702 is mounted on the motor frame 701 to drive Gear 1 602 to rotate, which in turn drives Gear 2 603 to rotate through the chain 604, so that the blank moves on the chain 604.

[0031] Please see Figure 2 In this embodiment, a spacing adjustment mechanism 8 is provided at the bottom of the receiving and conveying bracket 3. The spacing adjustment mechanism 8 includes a bidirectional threaded rod 801, which is rotatably connected to the bottom of the receiving and conveying bracket 3. Two movable frames 802 are threadedly connected to the outer circumference of the bidirectional threaded rod 801. The two movable frames 802 are respectively fixedly connected to the middle of the top of the two support plates 601. A handle 803 is fixedly connected to both ends of the bidirectional threaded rod 801.

[0032] Specifically, the bidirectional threaded rod 801 is located at the bottom of the receiving and conveying bracket 3. By rotating it, the relative position of the two moving frames 802 can be changed. The handles 803 are located at both ends of the bidirectional threaded rod 801, which allows the operator to manually rotate the bidirectional threaded rod 801. By rotating the handles 803, the bidirectional threaded rod 801 rotates, which in turn drives the moving frames 802 to move, thereby adjusting the distance between the two support plates 601 and ensuring that the billet can be stably transmitted at a suitable distance.

[0033] Please see Figure 3 and Figure 4 In this embodiment, a tensioning mechanism 9 is provided on the top right side of the support plate 601. The tensioning mechanism 9 includes a fixed frame 901, which is fixedly connected to the top right side of the support plate 601. A sliding block 902 is slidably connected inside the fixed frame 901. Two springs 903 are fixedly connected inside the fixed frame 901. The other ends of the two springs 903 are fixedly connected to the left side of the sliding block 902. A gear 603 is rotatably connected to the bottom of the sliding block 902.

[0034] Specifically, the fixed frame 901 provides support for other components of the tensioning mechanism 9. The combination of the spring 903 and the sliding block 902 can automatically adjust the position of the gear 603 according to the working state of the chain 604, ensuring that the chain 604 always maintains appropriate tension. When the chain 604 becomes loose due to long-term use or other reasons, the elastic force of the spring 903 will push the sliding block 902 to move, thereby adjusting the position of the gear 603, tightening the chain 604, preventing the chain 604 from loosening or falling off, and ensuring the normal operation of the non-standard chain conveying mechanism 6.

[0035] Please see Figure 2 and Figure 3 In this embodiment, a material dropping mechanism 10 is provided on the top of the support plate 601. The material dropping mechanism 10 includes a material dropping cylinder 1001, which is fixedly connected to the top of the support plate 601. A material dropping rod 1002 is fixedly connected to the output end of the material dropping cylinder 1001.

[0036] Specifically, the material discharge cylinder 1001 is set on the top of the support plate 601. After a certain amount of blanks are collected on the receiving and conveying bracket 3, the material discharge rod 1002 is pushed by the material discharge cylinder 1001 to push the blanks from the non-standard chain conveying mechanism 6 to the buffer mechanism 13 below, so as to realize the orderly discharge of blanks and prepare for the subsequent stacking process.

[0037] Please see Figure 1 and Figure 5 In this embodiment, a plurality of limiting frames 11 are fixedly connected to the top of the material carrying support 1, and a limiting rod 12 is fixedly connected to one end of each of the plurality of limiting frames 11. A buffer mechanism 13 is provided on the top of the material carrying support 1. The buffer mechanism 13 includes a plurality of support frames 1301 and a plurality of mounting frames 1303. The plurality of support frames 1301 and the plurality of mounting frames 1303 are fixedly connected to the top of the material carrying support 1. A buffer plate 1302 is slidably connected inside the plurality of support frames 1301. A buffer cylinder 1304 is fixedly connected inside the plurality of mounting frames 1303. The plurality of buffer cylinders 1304 are respectively fixedly connected to one end of the plurality of buffer plates 1302.

[0038] Specifically, the limiting frame 11 and the limiting rod 12 are used to limit the position of the billet on the material carrying support 1 to prevent the billet from shifting or falling during the transmission and temporary storage process. The support frame 1301 provides support for the buffer plate 1302, which is used to receive the billet falling from the unloading mechanism 10. The buffer cylinder 1304 can adjust the position of the buffer plate 1302 in a timely manner according to the falling situation of the billet, effectively buffering the impact force of the falling billet and protecting the billet from damage.

[0039] Please see Figure 1 , Figure 5 and Figure 6 In this embodiment, a billet collection mechanism 14 is provided at the bottom of the material support bracket 1. The billet collection mechanism 14 includes a collection cylinder 1401. The collection cylinder 1401 is located at the bottom of the material support bracket 1. Multiple fixing rods 1402 are fixedly connected to the output end of the collection cylinder 1401. A billet rack 1403 is fixedly connected to the outer periphery of the bottom of the multiple fixing rods 1402. A collection plate 1404 is fixedly connected to the top of the multiple fixing rods 1402. The collection plate 1404 is located on the opposite side of the multiple buffer plates 1302.

[0040] Specifically, the collecting cylinder 1401 is located at the bottom of the material carrying bracket 1. It is activated after the billets are stacked and reach a certain quantity. By driving the fixed rod 1402 to move, it drives the billet rack 1403 and the collecting plate 1404 to move, transporting the stacked billet rack 1403 to a suitable position, so that the rack full of billets can be moved away by a forklift or overhead crane. This realizes the automatic collection and transfer of billets and improves production efficiency.

[0041] The working principle and usage process of this utility model are as follows: When conveying and stacking wheel hub blanks, the drive motor 702 is started first. The drive motor 702 drives gear 602 to rotate, and gear 603 rotates in coordination through the transmission of chain 604, thereby realizing the stable conveying of wheel hub blanks by the non-standard chain conveying mechanism 6. When it is necessary to convey wheel hub blanks of different specifications, the operator turns the handle 803, which drives the bidirectional threaded rod 801 to rotate, thereby driving the moving frame 802 to move, and then adjusting the spacing of the non-standard chain conveying mechanism 6 to adapt to the blank size. During the conveying process, the spring 903 and sliding block 902 of the tensioning mechanism 9 will automatically adjust the position of gear 603 according to the working state of chain 604, ensuring that chain 604 always maintains appropriate tension, preventing chain 604 from loosening or falling off, and ensuring that the blanks can be continuously and stably conveyed on the non-standard chain conveying mechanism 6, efficiently completing the early conveying stage of the stacking process.

[0042] When the billet on the receiving conveyor bracket 3 reaches a certain quantity, the dropping cylinder 1001 is activated, pushing the dropping rod 1002 to push the billet from the non-standard chain conveyor mechanism 6 to the buffer mechanism 13. The buffer plate 1302, supported by the buffer cylinder 1304, receives the billet, effectively buffering the impact of the falling billet and preventing damage. The buffer cylinder 1304 drives the buffer plate 1302 to be pulled away, and the billet falls smoothly onto the billet rack 1403. When the billet is stacked and reaches the specified quantity, the collecting cylinder 1401 is activated, driving the fixed rod 1402 to move, which in turn moves the billet rack 1403 and the collecting plate 1404, transporting the billet rack 1403 full of billets to a suitable position for easy removal by a forklift or overhead crane. This achieves automated operation of the entire wheel hub billet stacking process, greatly improving production efficiency while ensuring product quality stability.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
